45,294	Nov. 29, 1864	Milling Machine	Joseph R. Brown	Providence, Providence County, RI	From Studies in the History of Machine Tools by Robert S. Woodbury. "At the time the involute method of determining gear-tooth shapes had been shown (by mathematicians) to be superior to the epicycloidal method, but practice lagged far behind as practical men stuck to the traditional epicycloidal approach. The first version of that Brown & Sharpe gear-cutting machine, introduced in 1864 or 1865, had available sets of 24 cutters for epicycloidal gears, sufficient to cut all gears of a given pitch, from a 12-tooth pinion gear to a rack. In 1867 they introduced cutter sets for involute gear teeth, each set requiring significantly fewer cutters than the equivalent epicycloidal set, and was therefore less expensive. As the only maker, at the time, of gear-cutting machines, Brown & Sharpe's introduction of involute cutters was vital to the move away from epicycloidal gear designs."
46,521	Feb. 21, 1865	Screw Threading Machine	Joseph R. Brown	Providence, Providence County, RI
51,257	Nov. 28, 1865	Screw Cutting Machine	Joseph R. Brown	Providence, Providence County, RI	Abstract: My said improvement relates, first, to the means by which the rod or piece of metal from which the screw is to be formed is griped and held at the end of a revolving spindle; and it consists in combining with suitable griping jaws a set of wedges at the end of a rod or tube within the spindle, and a rotating screw for imparting a sliding movement longitudinally to the said rod or tube and the wedges thereon, so that the wedges are made to force the griping-jaws together to gripe the rod or piece of metal, and afterward to liberate the same while the spindle is revolving. My improvement relates, secondly, to the means employed to4 hold and control the operation of the threading-tool; and it consists in combining a tool-holder capable of holding a tap or die or other suitable threading-tool with a reversible clutch in such a manner that the holder and tool may slide and cut the screw-thread up to a given point, and then be liberated by the clutch and revolve with the threaded-screw until the revolution of the spindle is reversed, when the tool-holder is arrested and held from turning while the tool is being withdrawn from the threaded screw. Claims: The combination of a set of griping-jaws, l, and a set of wedges on a sliding rod or tube, m, or its equivalent, with a hollow screw, F, the same being constructed and arranged to operate within a revolving spindle, substantially as described, for the purpose specified. 2. The combination of the threading-tool holder and the reversible clutch, constructed and arranged to co-operate with a revolving spindle.

187,770	Feb. 27, 1877	Grinding Machine	Joseph R. Brown (deceased), estate of	Providence, RI	Joseph A. Miller - patent attorney Figure I is a top view of the improved grinding-machine. (The two broken lines indicate the position of the center-line of the table to which the head and foot stocks are secured when the table is swung on either the central or the end pin.) Pig. 2 is a front elevation of the machine. Pig. 3 is an enlarged sectional view through the center of the grinding-machine, the base being shown as broken off. Fig. 4 is a plan view of the laterally-swinging base-plate, on which the wheel-arbor is supported, in different positions. The object of this invention is to so construct a grinding-machine that the same shall be adapted to do a great variety of work a machine on which straight, tapering, curved, and irregular work, either inside or outside, can be ground with great accuracy. The nature of the invention consists in the arrangement of the parts, by which the relative positions of the table, the head and foot stocks, and the wheel-arbor, can be adjusted to adapt the same to a great variety of work and under all the changes control the adjustment with the greatest nicety.

202,866	Apr. 23, 1878	Micrometer Gage	George M. Pratt	Middletown, Middlesex County, CT	This invention relates to that class of micrometer gages having horseshoe shaped frames, in which the object to be measured is clamped between a suitable abutment and the tip of a micrometer-screw. In order that the measurement by such an instrument shall be absolutely correct, it is necessary that the surfaces of said abutment and screw shall be perfectly smooth, and they should, therefore, be made as hard as possible, to resist abrasion and wear. In hardening these surfaces, the ordinary methods of tempering have been employed, the screw being completely formed and adjusted while the metal of which it was composed was soft, and afterward tempered. In thus tempering the screw after its complete formation, it has been found that its adjustment is always more or less impaired, as the heat necessary in the process of tempering expands the metal, a portion of the expansion being permanent, and the contraction, on cooling, unequal so that, though a micrometer-screw should be perfectly accurate before being tempered, it would often, after tempering, be found so altered as to materially affect its accuracy in the minute measurements for which such instruments are employed, and is then worthless for its intended purpose. Besides, when the screw is first perfectly accurate, if its tip becomes much worn, a new adjustment or the substitution of a new screw is necessary in either event involving more or less expense. The bar forming the horseshoe or U shaped frame of such an instrument has heretofore been formed of uniform width and thickness throughout its length; and, in order to give it sufficient rigidity to prevent springing, this frame has been of inconvenient weight and bulk. To obviate the necessity for heating the screws for tempering, to provide for their easy repair, thus reducing the expense, while preserving the accuracy of micrometer-gages, and also to render the frame of such an instrument strong, light, and of elegant shape, is the object of my invention; and it consists, first, in a micrometer-gage screw, having a socket formed in its end, and provided with a separate tip of tempered steel or similar hard material, whereby the necessity for heating the screw, in order to temper the tip, is obviated, and said screw is rendered easy to repair by the simple replacement of a worn tip by a new one, properly hardened and adjusted; second, in forming a micrometer-gage frame of an approximately crescent shape, or semicircular and tapering from its middle portion to its ends, in which the screw-bearings are located.
216,998	Jul. 01, 1879	Improvement in hair-clippers	Cyrus Carleton	Providence, RI
222,744	Dec. 16, 1879	Improvement in Measuring Scales and Rules	Lucian Sharpe	Providence, Providence County, RI	Three sided "draftsmen rule" made of sheet brass formed into a seamless tube and then formed into a triangular shape instead of using boxwood. Sold by DBS as the No 72.
226,162	Apr. 06, 1880	Compensating Errors in Screw Dividing Engines	Samuel Darling	Providence, Providence County, RI
241,879	May. 24, 1881	Gear Wheel Cutter	Edwin L. Parsons	Providence, Providence County, RI	Abstract: The object of my invention is to set the cutter in the gear-cutting machine central with the spindle upon which the blank is held; and it consists in making a small line about two one-thousandths of an inch in width, (0.002,) more or less, in the center of the peripherical contour of one or more teeth of the cutter, transverse with its axis; or a conical or some other form of groove or mark may be used instead of a small line. Heretofore the eye has been the principal guide in seating gear-wheel cutters. The points of the cutter-teeth being rounding, the center cannot be found with a graduated rule or dividers, and it would be too difficult and expensive, if practicable, to make an instrument to fit and accompany each size cutter to be used as a guide in setting it. It is well known that there is a great difference in the natural faculty of mechanics for doing such work by the eye. Some can work quite accurately, while others cannot depend upon their eye for anything accurate. Claim: A gear-wheel cutter having a line in the center of the peripherical contour of one or more of its teeth as a guide in setting the cutter central in the gear-cutting machine.
253,266	Feb. 07, 1882	Screw Nut	Samuel Darling	Providence, RI	Abstract: The object of my invention is to so construct r the nut that by its proper adjustment and use the thread of the nut and the thread of the screw upon which it runs may both be made and kept of the same anti uniform pitch, and all longitudinal play of the nut on the screw prevented, and that it may he adjusted with facility and with the great accuracy which its use requires; and my invention consists in making the nut in two parts, one part being permanently fixed to the machine and the other a part made adjustable; in making the fixed part of the nut and a holder for the adjustable part in one piece, the adjustable part being held in the holder in exact line with the fixed part; in attaching the adjustable part of the nut to the holder by means of a screw cut upon its outer contour corresponding to and accurately fitting a female screw in the holder; in providing the adjustable part with a radial index-arm by which, in connection with a graduated scale, it can be turned and adjusted, and in arranging the fixed part of the nut and the holder for the adjustable part upon bearings to be automatically turned when the machine is in operation; in making the threads of the nut and the threads of the screw upon which it runs of the same and uniform pitch by attrition, the nut being alternately adjusted and run on the screw for that purpose and, also, in making both parts of the nut and holder of the same kind of metal of which the screw is made upon which the nut is to run. Claim: A nut made in two parts for the leading-screws of dividing and screw-cutting engines, micrometers, and all screws that require great accuracy, one part being fixed and the other adjustable independently of the fixed part, the fixed part and a holder for the adjustable part being made in one piece or separate pieces rigidly held together.
287,420	Oct. 30, 1883	Micrometer	Samuel Darling	Providence, RI	Abstract: The object of this invention is to make a micrometer having a screw and a nut in which there shall be no perceptible play between the threads of the screw and the nut, a micrometer in which the screw will revolve much farther relative to the motion of the cross-hairs than in the micrometers heretofore made, and a micrometer having a substitute for the common cross-hairs, (spider's web,) by which measurements can be made with greater accuracy and uniformity and it consists in making a micrometer having a V-thread screw and nut, the nut being split at one end, and using a screw for tightening the nut; in making the frame that carries the cross-hairs with a very small hard abutting-piece that shall come against the end of the screw, which is also to be made hard and preferably small; in making a micrometer having two screws on the same piece, each made of a different pitch, and a whole or split nut for each part of the screw, one nut and the corresponding screw being attached to the frame that carries the cross-hairs; in making a micrometer having small wires, which may be of glass or any suitable material, instead of spider webs, and in making a micrometer having short cross-wires parallel with and opposite to each other, leaving a space between them, and in various positions, so that the operator can have several points to guide him in adjusting the micrometer to the line on the article to be measured, and in making a micrometer having one or more movable pieces to hold the wires for the purpose of adjustment, all to be constructed and used as more fully described in the folio wing specification. It is well known to mechanics that a screw loose in the nut cannot be depended upon for great accuracy and uniformity in measurements, notwithstanding the slack may be taken up by a spring, as particles of matter are liable to get between the threads and cause errors. That difficulty is avoided in this improved micrometer. From experiment it is believed that the cross-hairs in a micrometer made according to this improvement can be adjusted to a line a number of times say five, more or less, within an error of .00005 of an inch. It greatly facilitates the adjusting of the cross-hairs to a line to have the screw move a considerable part of a revolution for each division of the index-wheel. It is difficult to move the screw made in the ordinary way little enough to adjust the cross-hairs in the most accurate manner, and the difficulty in moving it little enough often influences the operator to accept an adjustment as correct with which he is not fully satisfied. Claim: A micrometer having a nut in or attached to the case C, which encloses the cross- hair sliding frame ID, the nut being split or made in two parts.
289,513	Dec. 04, 1883	Micrometer Gage	Samuel Darling	Providence, RI	Abstract: The end in view in this invention is to so construct a micrometer gage that the index sleeve may be comparatively short say one inch long, more or less and be used to indicate correctly on a gage of any desired size and length of screw, and it consists in making the screw movable and adjustable in the sleeve. Claim: A micrometer-gage having, in combination, a frame, A, provided with a graduated fixed screw-nut, E, a revolving measuring-screw, B, and a graduated sleeve, D, said sleeve being shorter than the measuring capacity of the gage, and arranged to be changed and fastened to different parts of the screw and pass to and fro over the screw-nut E.

332,118	Dec. 08, 1885	Adjustable Anvil for Micrometer Gages	Frank Spaulding	Providence, Providence County, RI	My invention relates to the adjustable anvils of all kinds of micrometer-calipers; and the object of my invention is to avoid a certain defect in such anvils as heretofore constructed. The purpose of adjustable anvils for micrometer-calipers is to compensate for wear in the instrument so as to maintain the zero position of the sliding scale. This has heretofore been attempted by the use of an adjustable anvil which rotates throughout its entire length, so that the anvil-face is varied in position with every adjustment. It has been found very difficult to construct these adjustable anvils with absolutely true anvil-faces and such imperfection, together with the effect of wear upon the anvil-face, has rendered the accurate adjustment of the implement exceedingly difficult if not impossible. In order to overcome this defect, I construct the adjustable anvils in two parts, one of which, the face part, has only a simple sliding movement, while the other, the screw part, turns and works in the screw-thread. Thus the anvil-face preserves at all times its original position, and if there be any defect in its construction such defect may be readily and accurately compensated for.

487,410	Dec. 06, 1892	Automatic Stop for Micrometer Gages	George Sylvia	Waltham, Middlesex County, MA	My invention relates more particularly to hand-tools such as watchmakers' micrometer-gages, calipers, and screwdrivers in which delicate measurements and the most perfect accuracy and delicacy of adjustment are essential to the best workmanship. The tools now used in watchmaking and the manufacture of delicately constructed instruments are adjusted with the greatest accuracy and are made to record or to detect the slightest variations in the work to which they are applied; but in the use of such instruments the results are found to be unsatisfactory, because varying according to the different workmen who use them, on account of differences in their nicety of touch, and often in the work of the same workman, according to the care taken by him, and also because with careful workmen much time is consumed in securing the desired accuracy. In the use of the micrometer-gage a slight overpressure upon the measuring ends when in contact with the work will expand or spread the ends apart and produce inaccuracies in the measurement of the work done. The object of my invention is to overcome these difficulties and defects by providing for micrometer-gages, watchmakers' screwdrivers, and other instruments requiring great delicacy of adjustment a device by which the forward movement of the screw turned by the hand will be stopped automatically when the desired contact has been made with the work for the purpose of measuring the same or in setting the screw or for other similar purposes. Another object of my invention is to increase the rapidity of the forward movement of the micrometer-gage screw or other forward-moving shaft under the same motion of the hand or fingers as is now used in these instruments as at present constructed. My invention has also in view the production of means by which the rotating sleeve upon the spindle of the gage or other tool may upon being reversed immediately lock with, the spindle and rotate with the same.
491,521	Feb. 14, 1893	Tail Stock for Milling Machines	John W. Boynton	Providence, Providence County, RI	My invention has for its object to provide means for readily and accurately effecting all the necessary or desired adjustments of the back center of a milling machine, including not only lateral and vertical but angular adjustments thereof.

495,915	Apr. 18, 1893	Micrometer Gage	Frank Spalding	Providence, Providence County, RI	This invention has reference to improvements in gages, which are particularly adapted to those of the caliper order. The object of this invention is to increase the measuring capacity of gages for making delicate measurements without increasing the traverse of the measuring mechanism. Another object of the invention is to produce a gage in which an adjustable measuring-post is carried by a traversing-indicator. Still another object of the invention is to increase the measuring capacity of a caliper gage without obstructing the anvil end of the frame. The invention consists in the combination with the traverse-screw of an adjustable measuring-post. The invention further consists in the peculiar construction of the traverse-screw having means for securing a measuring-post thereto, together with such other peculiar features of construction and combination of parts as will hereinafter be more fully described and pointed out in the claims

842,989	Feb. 05, 1907	Spiral Cutting Machine	Richard T. Wingo	Providence, RI	WilMarth H. Thurston - patent attorney The invention relates more especially to machines for cutting spirals in which the work is carried by a rotary blank support and is acted upon by a rotary cutter, the axis of which is at an angle to the axis of the blank-support and in which either the cutter or the blank is reciprocated parallel to the axis of the blank. In such machines the cutter should be out of cutting relation during the return movement of the reciprocating support, and this may be provided for by moving either the cutter or the work. It has heretofore been customary to throw the blank and cutter out of cutting relation by a swinging movement of either the cutter or blank support. The clearing movement with such construction is in the arc of a circle with a constant liability that the cutter may contact with the wall of the cut as the blank and cutter are thrown out of cutting relation, and the danger of such action increases as the angle between the axes of the blank and cutter increases. This objectionable feature in the prior constructions is eliminated by certain features of the present invention winch provide for a relative movement between the cutter and blank at right angles to the axes of the blank and cutter in clearing the cutter from the blank, that is to say, if the axes of the blank and cutter are arranged horizontally, as is customary, the blank and cutter are thrown out of cutting relation by a direct vertical movement either of the blank or cutter, and thus all danger of injury to the work by the cutter in clearing the work is eliminated. It is preferred to move the cutter at right angles to the axes of the blank and cutter in throwing the blank and cutter out of cutting relation rather than to move the blank, and certain further features of invention relate to the construction and arrangement which provides for such movements of the cutter. In this class of machines the blank and cutter should be in cutting relation whenever the movement of the reciprocating support is forward or in the direction of the cutting movement and should be out of cutting relation whenever the movement of such support is, in the direction of the return or non-cutting movement. To insure this, the mechanism for throwing the blank and cutter into and out of cutting relation is so controlled by the device for alternately connecting the reciprocating support with the feed mechanism and the return mechanism that the operation of such device in connecting either mechanism with the -support to reverse its previous movement results in the operation of the mechanism for throwing the blank and cutter into and out of cutting relation. Another feature of invention relates to the means for operating the mechanism for throwing the blank and cutter but of cutting relation which insures the proper timing of such mechanism under all conditions. This mechanism is driven by a clutch which is intermittently thrown into and out of operation by the cooperation of rotary and non-rotary members, the rotary member or members, as the case may be, being carried by the clutch and the non-rotary member or members being movable into and out of the path of the rotary member or members and the members being so arranged and operated that in disengaging a non-rotary member from a rotary member to throw the clutch into operation a non rotary member is moved into the path of a rotary member. Thus the operation of the devices for throwing the clutch into operation sets devices for throwing it out, so that there is no-danger of failure to throw out at the proper time or of operating improperly. Further features of invention relate to the construction of the mechanism for throwing the blank and cutter out of cutting relation and locking it in position between operations

Anthony	Providence, RI	"The invention relates to an attachment for screw-machines, and has for its object to provide an attachment whereby screw-threads of any form, depth or pitch may be rapidly produced. Ordinarily in these machines the screws are cut by means of dies, but there is a limit to the depth and pitch of a screw-thread which can be properly and advantageously cut by a die. Heretofore when it has been desired to produce screws having threads of a greater depth or pitch than could be conveniently cut by a die, it has been customary to cut such screws in a lathe by means of an ordinary lathe-tool. But this involves repeated passes of the tool along the screw-blank, a greater or less number of passes being required according to the depth of the thread to be cut. The object of the present invention is to provide an attachment whereby threads of a depth or pitch which could not be properly cut by means of a die may be rapidly produced and with only a single passage of the cutting tool past the work..."

1,906,062	Apr. 25, 1933	Index Center	John Harley	, Scotland	Joseph A. Miller - patent attorney This invention relates to index centers, and more particularly relates to the indexing discs, the primary object of the invention being to enable the work to be turned throughout a greater range without changing the disc. Index discs of common usage are nominally used for dividing a circle into a definite number of equal parts (not degrees 10 and minutes) in the milling of teeth and gear wheels, and hexagonal and square milling of shafts. The method usually adopted for angular indexing is as follows: Divide 540 by the total number of minutes to be indexed. If the quotient is approximately equal to the number of holes in any index circle available the angular movement is obtained by moving the crank one hole in 20 this index circle; but if the quotient is not approximately equal, multiply it by any trial number which will give a product equal to the number of holes in an available index circle and move the index crank as many holes as are indicated by the trial number. If the quotient of 540 divided by the total number of minutes is greater than the number of holes in any of the index circles, it is not possible to obtain the required movement for the angle by simple indexing. This shows that, only some of the angles in degrees and minutes, can be obtained accurately by simple indexing, and compound indexing, which would be more accurate, involves greater calculations on the part of the workman, and leads to errors. The above method also shows that for different angles, different discs are often required, and it is only possible to turn the work through this angle and back to zero; therefore, it is not possible to turn the work accurately through a succession of angles in degrees and minutes in many cases. If a change of disc is necessary it would be impossible to place the second disc in the same position as the first one, due to the index crank not being opposite a hole. The present invention therefore aims to provide a disk which overcomes the objection supra/and in which when milling at an off angle is required the templets which are made to a protractor and which do not give the same degree of accuracy and are more costly, are dispensed with.

1,952,432	Mar. 27, 1934	Grinding Machine	Frederick S. Haas	Cincinnati, OH	Abstract: An object of the invention is the provision of 6 improved mechanism for actuating a movable slide of a machine tool organization. Another object of the invention is the provision of improved means associated with the tool slide of a machine tool organization to insure 0 the retraction of the slide to carry the tool a sufficient distance away from the work while same is being replaced so that no inadvertent engagement between the work and tool may occur. Another object of the invention is the provision of automatic mechanism for retracting and advancing a tool slide relative to the work which supplements the normal feeding mechanism of the slide. A further and specific object of the invention is the provision of a grinding machine having a grinding wheel slide movable toward and from the work including improved means supplementing the normal feeding means so that at the completion of the grinding operation and upon reversal of the feeding means a certain definite retraction of the slide takes place before the automatic retraction of the slide to permit replacement of a work piece in the machine. Claim: In a machine tool organization the combination of a bed, a slide carried thereby and movable relative thereto, means for actuating the slide at a slow rate including a shaft, means f or actuating the slide at a rapid rate including a piston, an hydraulic medium for actuating this piston, a shiftable reversing valve controlling the direction of flow of the medium and direction of movement of the piston, and means operatively connecting the valve with the shaft whereby actuation of the shaft in one direction effects instantaneous shifting of the valve and actuation of the shaft in the other direction effects a delayed shifting of the valve.

2,068,529	Jan. 19, 1937	Grinding Machine	William G. Baldenhofer	Springfield, Clark County, OH	This patent was listed on a Thompson Grinder Co. patent plate, and also on a Brown & Sharpe patent plate. Abstract: This invention relates to improvements in grinding machines of the class known as surface grinding machines, and more particularly to that class in which the work-holder and tool-holder are reciprocally operated by fluid motors, the fluid preferably being a mineral oil under pressure. In machines of this class the work-holder is reciprocated by means of a fluid motor consisting of a cylinder, piston and piston rod. The toolhead is usually advanced or retracted in successive intermittent movements of varying extent by a similar motor, the intermittent movements being timed to occur at the ends of the working strokes of the work-holder. The grinding operation is performed on the work supported on the work-holder by peripheral contact of a rotatable grinding wheel, which is mounted on the outer end of a wheel spindle supported in a horizontally disposed toolhead in such manner that the longitudinal axis of the spindle is located at right-angles to the direction of travel of the work- holder, whereby a flat surface is produced on the work by feeding the wheel across the work in successively intermittent movements. The machine described in the present specification follows a customary practice in providing reversing mechanism which is operated by stop- dogs adjustably secured to the work-holder, this mechanism governing the reversals of the work- holder, and also by the provision whereby the fluid under pressure is supplied to the separate fluid motors from a common source. In the present machine the intermittent feed imparted to the toolholder is obtained by supplying successive predetermined quantities of fluid to the same end of the cylinder of the toolholder motor, and both the toolholder motor and the work-holder motor are supplied from the same source of fluid under pressure. One of the disadvantages of such an arrangement has been that due to varying fluid pressures when the speed of the work-holder is changed, successive charges of fluid of a different quantity will be 1admitted to the toolholder motor resulting in a change in the extent of the intermittent feeds of the toolholder. If the speed of the work-holder motor is decreased, the successive intermittent movements of the toolholder become greater, and 5if the speed of the work-holder motor is increased the extent of the successive feeds of the toolholder is reduced. As a consequence of this, unless provision is made otherwise for preventing it, the quantity of the successive fluid charges admitted to the toolholder motor will obviously vary at different speeds of the work-holder resulting in a variation in the feed of the toolholder. One of the objects of this invention is to overcome this objection by providing that uniform successive charges of fluid will be admitted to the toolholder motor regardless of the speed of the work-holder. Another object of the invention is the provision of means incorporated in a unitary hydraulic valve control mechanism, whereby a smoothly operating machine is afforded. One of the advantages of fluid motor drive is that infinite gradation of work-holder speeds is readily obtainable. Ordinarily, however, the operation is hampered by vibration due to shock at work-holder reversals. The present invention provides a cushioning effect whereby all shock is eliminated. Another object is the provision of improved means for controlling the extent of each intermittent movement of the tool-head, which means may also be employed to alter the direction of movement of the toolholder. Another object is to provide means acting in combination with the devices just mentioned which control the toolhead movements whereby a continuous movement may be given the toolhead in either direction, the direction being under the control of the intermittent control means. Another object is to provide that the toolhead is maintained in position during the intervals between times of movement; that is, the toolhead is substantially in a "locked" position. Claim: In a machine of the character described, a plurality of fluid motors operating from the same source of fluid supply, manual means for regulating the fluid supplied to one of said motors, and fluid admission means operated directly by fluid for admitting successive predetermined charges of the fluid to another of said motors also operable from the same source of fluid supply.
2,068,840	Jan. 26, 1937	Milling Machine	Arthur F. Bennett	West Barrington, Bristol County, RI	Gary and Jenney - patent attorneys We have seen this patent number, one of about 50 listed, on a No. 2B Plain Mill from Brown & Sharpe. Abstract: The present invention relates to improvements in milling machines, and is herein disclosed as embodied in a manufacturing type of milling machine including a work supporting table, electrically driven and mounted on ways on a fixed base, together with a cutter spindle which is also electrically driven and is mounted on a carriage for vertical adjustment toward and away from the table. It is a principal object of the present invention to provide novel and improved means for controlling the operation of the work supporting table and cutter spindle to permit a more efficient and safe manipulation of the machine by the operator, and also to insure a high degree of efficiency and accuracy in operation. It is a further object of the invention to provide certain novel and improved features of construction and operation of the several cooperating mechanisms of the machine to produce a better and more efficient machine. With these and other objects in view, as may hereinafter appear, certain features of the invention are concerned with the provision of a novel and improved electrical control mechanism for the machine, and more specifically with the provision of an improved switch mechanism for controlling the starting and stopping of the table and spindle motors. In order to secure a more accurate control in the stopping of the relatively high speed motors utilized, one feature of the invention consists in the provision of a novel and improved viscosity switch which may be mounted directly on the armature shaft of the motor, and is well adapted for consistent and efficient operation at the high speed of rotation developed by the motor shaft. Another feature of the invention consists in the provision of electrical control mechanism for controlling the operation of a viscosity plugging switch to prevent over-travel of the switch mechanism in plugging the motor to a stop, with a consequent tendency for the motor to kick in a reverse direction. Another feature of the present invention consists in the provision of a control mechanism for braking the cutter spindle to a stop which utilizes the braking force of the motor, and causes a mechanical brake to be applied only after the motor and spindle driven thereby have been appreciably slowed down to reduce so far as possible the wear on the brake linings. Certain other features of the invention consist In the provision of a novel safety stop switch for the table motor and a jog switch for the spindle motor which serve to permit a more versatile and complete control of the operation of the machine by the operator. Another feature of the present invention consists in the provision of a novel and improved g pick-off gear case which is well adapted to facilitate the changing of gears, and is so arranged as to prevent movement of the table driving connections including the gears under power with possible injury to the operator while the gear case is open.

The attachment housing sleeve is supported in a split bracket, Fig. 12, carried at the side of the standard wherein the sleeve is rotatably and axially adjustable ; the forward end of the sleeve carries a rotatable head, Fig. 9, which houses the vertically adjustable attachment spindle. This spindle is driven by bevel gearing from a central spindle, which runs the length of the attachment sleeve and is rotatably mounted therein. A long gear 60 integral with the spindle is driven in all positions of axial adjustment of the spindle by gearing connecting the gear 60 with the main spindle of the machine. The gearing for this purpose is housed in a casing, Fig. 12, rotatable about the axis of the main spindle and held, with the last wheel of the driving train in alignment with either one of the openings for the over-arms, or with the attachment bracket, by a stud. This enables the attachment housing to be positioned in the place of either of the over-rms with the drive to the main spindle in engagement. One of the wheels of the train may be slid out of engagement to disconnect the drive to the attachment. A hinged bracket, Fig. 4, is clamped around the over-arms and a part of the attachment to obtain rigidity, and graduations indicate the inclination of the attachment spindle to the horizontal. The end of the attachment driving spindle, Fig. 8, is supported in a bearing 105 at the rear end in the sleeve 41, a telescopic guard encloses the end of the sleeve, the parts of the guard being forced into the collapsed position by a tension spring and the outer end of the sleeve drawing these apart when the attachment is moved axially rearwardly such as when positioning the attachment in the inoperative position, Fig. 1. A lubricator, Fig. 8, is connected to a pipe 108 which passes into the hollow end of the spindle 60 for distribution. Claim: A milling or like machine tool provided with over-arms comprising a standard, a main spindle mounted for rotation on the standard, an attachment having a housing carrying a drive spindle, means on the side of the standard for supporting the attachment housing whereby the latter can be adjusted longitudinally and driving means between the main spindle and the attachment spindle for maintaining continual driving engagement with the latter in any of its positions of adjustment while leaving the main spindle free to function in its normal manner.

491,152	Aug. 26, 1938	Improvements in or Relating to Milling Machine-Tools	none listed	Providence, Providence County, RI	Abstract: A milling-machine has a work-supporting table, a longitudinally movable support therefor, and driving connections for controlling the rate and direction of movement of the table and support comprising a prime mover, a transmission train for moving the table relatively to the support, another transmission train for moving the support, and separate control devices for each train to give starting, stopping and reverse, and a single control element which enables the table transmission train to be driven either directly from the prime mover or through the support transmission train. The machine comprises a main column, Fig. 1, on which a cutter spindle is rotatably mounted. The machine is also provided with a work-supporting table mounted to slide on ways formed on a swivel mounting which forms part of a saddle, which is mounted for transverse movement on ways 32 carried on the knee. The knee unit is built up of three relatively movable supports comprising a vertically movable knee member arranged to slide in vertical ways formed on the front side of the column, and adjustably supported by the usual telescoping screw, and a swivel knee member, which carries the saddle ways 32 and is arranged to swing about a transverse axis. The swivel knee member is in turn carried on a knee rail, which is mounted on longitudinally extending ways formed on the vertically adjustable knee member to provide for longitudinal reciprocating movement of the entire assembly. The work table derives its movements from a feed screw, Fig. 2, driven through a reversing clutch, which may be operated by hand or by adjustable stops carried by the table. A further hand-controlled clutch enables the screw to be connected for table operation or to be disconnected when the table feed is not required. The reversing bevels are driven from a vertical shaft, which is driven in turn from a cross-shaft 66 through bevel gearing connected to a bracket, Fig. 6, which permits all the possible movements of the table described above without affecting the drive; the shaft 66 is driven from a longitudinal drive shaft. The knee support, Fig. 2, is moved by a feed screw, which is driven together with the shaft by gearing arranged in a gear-box and driven from a shaft, termed the prime mover, which may be driven from a source of power through further conventional rate-charging mechanism. In the gear-box, Fig. 7, the clutch sleeve, which drives the feed screw is adapted to be driven in forward or reverse directions by gearing from the prime mover, and the clutch sleeve may be moved to obtain these results or to stop the drive to the screw by a hand-control, Fig. 2, or from the movements of the knee support through a slidable control rod 154 carrying adjustable dogs. A gear wheel, Fig. 7, slidable on the end of the shaft by means of a hand-control knob enables the shaft to be driven directly from the prime mover 122 through the gears, or in series with the knee support drive by connection with the gear on the shaft. For an extremely rapid or extremely slow operation of the table the table transmission train is connected in series with the knee support clutch and the table feed screw is connected to drive the table, the speed of the table is then the resultant of the combined driving rates of the table and the knee support. The machine is also adapted for spiral or spiral taper milling work, Fig. 1, by using a spiral head 102 bolted to the table and disconnecting, by means of the clutch, the table from the feed screw 46, all the necessary movement being obtained from the knee support feed gear and from the gear driven by the feed screw. Claim: A milling machine having a work supporting assembly including a work table, and a longitudinally movable supporting member therefor, said table being so longitudinally movable relatively to said supporting member, in which driving connections are provided for controlling the rate and direction of travel of the work table comprising a prime mover, a transmission train from said prime mover for moving the table relatively to the support, a transmission train from said prime mover for moving the support, means including separate control elements associated with each of said trains for controlling independently starting, stopping and reversal of each of the table and the support, and a driving connection including a single control element which enables the table transmission train to be selectively driven, 75 either directly from the prime mover, or through the support transmission train whereby the table and support may be simultaneously controlled.

2,615,372	Oct. 28, 1952	Milling Machine Spindle Axial Shift Control	Edward E. Coffin	Providence, RI	Maxwell Fish - patent attorney The present invention relates to improvements in machine tools, and more particularly to a control device adapted for controlling the position axially of a milling cutter spindle and its axially shiftable supporting sleeve. The invention is herein disclosed in a preferred form as embodied in a horizontal-type milling machine which may be similar to that illustrated in U. S. Letters Patent to Bennett and Krause No. 2,068,840, dated January 26, 1937, for; Improvements in Milling Machines. The machine referred to, is provided with a longitudinally moving work table, a spindle support, and a milling cutter spindle disposed to rotate on a horizontal axis transverse to the direction of table movement within a spindle sleeve which is mounted on the spindle support to permit a limited axial adjustment of the sleeve and spindle relative to the table. For effecting such axial adjustment, there is provided a manually operable racking control and a manually operable clamping device which serves to rigidly clamp the spindle sleeve in its adjusted position. In the machine referred to, adjustment of the spindle axially and the clamping of the spindle in adjusted position are effected by separate rotatable control knobs located at one side of the spindle head. An axial adjustment of the spindle when made by manipulation of the manual controls referred to, would normally be maintained during the entire operation upon one or more work pieces as, for example, during the continuance of an automatic operation in which the table and work supported thereon are fed at a feed rate past the milling cutter for the performance of a milling cut thereon, and are then returned at a rapid traverse rate in the reverse direction to the starting position for the removal of the work and the substitution of a new work piece in operating position on the table. In the performance of face milling operations in which a face milling cutter is moved at a predetermined depth across the face of the work piece and is then returned at a rapid traverse rate in the reverse direction to the starting position in brushing contact with the previously milled surface of the work piece, it has been found, particularly where high speed cutters having hardened edges of cemented carbide are employed, that there is a tendency for the cutting surface to be chipped or otherwise marred by the light frictional contact with the work which takes place during the return movement.

6,243,965	Jun. 12, 2001	Electronic Micrometer	Adriano Zanier	, Switzerland	Jacobson, Price, Holman & Stern, PLLC - patent attorneys Abstract The electronic micrometer includes a casing defining at least an internal volume, in which are disposed a sleeve having an at least partially threaded inner surface. A screw is engaged in this sleeve and is able to be put in rotation with respect to the sleeve in such a way as to displace itself along the longitudinal measuring axis (x) of the device. There is a capacitive system of measurement for measuring the relative rotation of the screw with respect to the sleeve and for determining, starting with that measurement, the longitudinal position of the screw. The casing comprises two half-shells. At least one filiform joint allows the internal volume inside the casing to be sealed. Other sealing means are provided to prevent any infiltration of water or of dust into this internal volume. Accordingly, micrometer are protected. Claim: An electronic micrometer comprising: a casing including two half-shells, a pair of joints extending between said two half-shells for forming said casing, and said joints including at least one filiform joint disposed in such a way as to prevent infiltration of water through an interstice between the two half-shells, and defining at least one internal volume, in which are positioned members forming said electronic micrometer, said members including a sleeve, at least partially threaded, a screw engaged in said sleeve and able to be put in rotation with respect to said sleeve in such a way as to displace itself along the longitudinal measuring axis of the device, an electronic measuring system able to measure the relative rotation of the screw with respect to the sleeve and to determine, starting from that measurement, the longitudinal position of the screw, and wherein said joints are disposed in such a way as to make the said internal volume fluid-tight.
