Claim:
The accompanying drawings show the improvement as an individual drive; but the prime object is to incorporate it into a machine-tool organization either as a variable-speed counter-shaft or it may be built directly into the machine-frame as, for instance, into the headstock of a lathe. The most acceptable method, however, for some classes of tools is to drive from a counter-shaft to the. upper shaft on the variator and couple the driven shaft or lower one to the first work-shaft of the machine. |

Frederick W. A. Herrmann |
Cincinnati, Hamilton County, OH |
Claim:
In the ordinary use of a shaping machine the carriage is fed, during an idle or non-cutting stroke of the ram. carrying the cutting tools, and this in either direction of carriage traverse. The feeding action, therefore, must be coordinately controlled with the movements of the ram, and the mechanism herein offers a quick and convenient change of the direction of carriage traverse without stopping the machine. The length of carriage traverse in either direction is micrometrically determined and regulated while the parts are in motion, so that the intermitting feed length can be varied with precision to set the cutting feed to that at which it is most suitable to the work machined. |

In machinery of this character, it is usual to mount the work upon a saddle which is feedable crosswise of the vertical plane in which the tool reciprocates, the saddle being slidable upon a rail, which is adjustable up and down with relation to the path of the tool. It is usual also to initiate the feeding movements from a fixed point of the machine, for instance, from the axis of rotation of the bull-wheel. The point for application of the feeding movements is therefore stationarily positioned, and the point for reception of the feeding movements at the feeding device is adjustable vertically in a right line, resulting in different distances between said points at different elevations of the rail. It is one of the objects of the invention to compensate for the variant distances between these two points. It is the object of the. present invention, further, to provide novel means whereby to automatically maintain the means for applying the feeding movements, the means for receiving the feeding movements, and,, the connecting means there between, at substantial distance and angular relations to each other. A further object is to provide novel means in the train of mechanism for accomplishing the feeding movements, whereby, to permit yield due to the variant distances between points in the power applying mechanism and the power receiving mechanism during adjustments to elevation of the power receiving mechanism; and,, further, to provide novel means, whereby to automatically return the yielding member of said mechanism to normal relation. A further object of the invention is to provide novel safety means whereby yield is permitted in the feeding train to compensate for obstruction to feeding movement of the element being fed, for instance, when the saddle reaches the end of its feeding path; and, further, to provide novel gauging means for the adjustments of lengths of feeding movements

Claim:
Our invention relates to means for driving the drill-spindle of a drilling machine at a plurality of selective speeds, and is an elaboration upon thefinechanism disclosed in Letters Patent of the United States No.1,297,256, granted 11 March, 1919, on the application of H. W. Schatz and A. M. Sosa, for improvements in drilling machines.
In the device of said patent a relatively small gear is associated with the drill-spindle for rotating the drill-spindle at high speeds, and a relatively large gear, exemplified as an internal gear, is associated with the drill-spindle for rotating the drill-spindle at relatively-slow speeds, these relatively high speeds and relatively slow speeds being multiplied by speed changing mechanism. |

Clutch Actuating Means for Machine Tools
|
William L. Schellenbach |
Wyoming, Hamilton County, OH |
Claim:
The present invention relates to clutch actuating means for machine tools, and is shown employed for actuating clutches in a lathe apron concerned in the feeding movements of the tool-holder. In machines of this character it has been usual to clutch and unclutch the clutch by means of a hand-wheel, usually of star form, and serving as a nut or bolt to draw the clutch elements together or to separate the same. It has been found in practice that sufficient clamping force cannot be exerted conveniently by mechanism of this character, especially when the feeding movement of the tool is resisted by great forces required in modern machine tool practice for taking heavy cuts, and under the modern practice of high cutting speeds, and it has also been found that release of the clutches by such means has also been difficult and inaccurate for definite limits of cutting movements, due, in part, to the fact that such hand-wheels turn during the feeding movements of the tool, making it difficult to properly grasp and to turn the same in clamping and in unclamping directions. It is the object of the present invention to provide simple means capable of exerting great power for operating a clutch, further, to provide such means with a control part which is relatively stationarily positioned, further, to provide improved clutching means wherein the clutch is normally in clutching relation, and a hand-lever normally stationary on its support and pivoted in such manner that the operator may conveniently exert great power for changing the clutch relations, and, further, to provide novel means whereby a cam-operating lever may be independently mounted in coactive relation with the clutch actuating part. |

Feeding Means for Drilling Machines
|
Albert E. Robinson |

Claim:
In mechanism of this character as heretotom usually employed it has been the practice to leave the manually operated handwheel for manually feeding the drill-spindle in operative relation when feeding the drill-spindle by power, with the result that when the drill-spindle was being fed by power the, hand-wheel was also rotating. This has been found to be an objectionable feature in mechanism of this character. |

Elevating Mechanism for Drilling Machines
|
Augustus M. Sosa |
Cincinnati, Hamilton County, OH |
Claim:
In metal drilling machinery there is usually a drive-shaft for imparting the desired rotative and feed movements to the drill-spindle, which drive-shaft rotates substantially continuously during the operation of the machine. There is also usually a train of gearing connected with the drive-shaft and continuously rotatable during the operation of the machine, for selectively rotating an elevating screw or an elevating nut in reverse directions for raising or lowering the drill-arm. In drilling machines as heretofore constructed this latter train of gearing has been directly connected with the driving means for operating the drill spindle, and, consequently, rotating throughout the time of operation of the machine. |

"The tool attachment herein disclosed is applied particularly for the formation of grooves in the surface of a cylindrical surface such as the periphery of a forging roll. In this type of work the grooves to be cut vary considerably as to longitudinal relief or depth and transverse relief. Each groove, formed in the roll, is a special cutting operation including shoulders and depressions throughout its length creating a problem in which movement of the tool must be definitely controlled and the repeating cuts uniform as the tool is moved into the work. For this purpose a relieving attachment is mounted on the cross slide of the lathe, in which a tool is mounted, on a pivoted tool holder rocked toward the work by means of templet cams..." |

Speed Indicator Means
|
William G. Hoelscher |
Cincinnati, Hamilton County, OH |
Claim:
In certain types of transmissions, such as those in the headstock of a lathe, a great many speed changes are necessary. It is also essential that the operator be able to read the indicator quickly. In the past, a great many indicator means have been provided, but they have not been compact and have not lent themselves to glance reading. Problems of compact indication arise particularly where the shifting is done mechanically. The present invention has particular application to a mechanical type shift, but is not limited to such use. In many instances, it is necessary to use a plurality of shifting levers; that is, one lever which shifts the mechanism into ranges, and another lever which shifts the mechanism into speeds within the respective ranges. The problem of keeping the indicator plate down to small dimensions and localizing the area in which the reading takes place where a great many speeds are employed has been a difficult one. |

Device for Resisting Movement of the Arm of a Drill
|
William G. Hoelscher |
Cincinnati, Hamilton County, OH |
Claim:
In certain types of work, such as for example, where a number of holes are to be drilled in a piece of work, considerable time is lost in clamping and unclamping the arm. In all radial drill structures heretofore known, the arm is arranged to swing freely; that is, it may either swing on the' column or it may swing as a unit with the column on a stump. A clamping device is provided for fixing the arm in a selected position so that the spindle is in registry with the hole to be drilled, whereby the arm cannot swing during the drilling operation. Where smaller holes are to be drilled and the drilling thrust is not great, it has been the practice to perform the drilling operations without clamping the arm, but this is not efficient, for dis-aligned or otherwise inaccurate drilling is apt to result. |

Mounting for Work Centers and the Like
|
William G. Hoelscher |
Cincinnati, Hamilton County, OH |
Claim:
This invention relates to an improved mounting for lathe centers and the like. These lathe center mountings are incorporated in the conventional tailstock as currently employed in lathe construction. More specifically, the invention relates to a mounting which will permit the work centering element to move relative to the tailstock when undue axial pressure is put upon the center as occurs when the work expands in the course oi the cutting operation.
In the development of this art there have been a number of devices disclosed and claimed in patents which have had the purpose of permitting expansion of the work. One of the earlier examples of this type of device is found in the patent to Müller, No. 1,318,223, issued 07 October, 1919, wherein a spring was employed to permit yielding of the work center in accordance with the expansion of the work. However, as the art of turning has developed, that is, with the advent of high speed tools and the procedure of dry cutting, the amount of heat generated in the work has increased. It will be seen that the tailstock structure and the work center mounting must be of rugged construction to properly support the work under these conditions and yet at the same time, the device, permitting axial expansion of the work, must do so readily and in the proper amount. |

Lathe Spindle Speed Control Mechanism
|
William G. Hoelscher |
Cincinnati, Hamilton County, OH |
Claim:
It is customary practice to provide a wide range of lathe spindle speeds in order to rotate the Work at a cutting speed recommended for the work diameter, material, type of cutting tool, and other determinant factors. To achieve maximum efficiency it is important that the head stock be capable of speedy and convenient spindle speed selection in setting up the lathe for the various jobs. For this purpose the head stock transmission is provided with shiftable range selection gears in combination with speed selection gears to provide several ranges and individual speeds within the ranges. An example of this arrangement is disclosed in the patent to William G. Hoelscher, No. 2,332,381, issued 19 October, 1943. This transmission may be assembled to provide either twenty-seven, eighteen or nine speeds by making a relatively simple change in the gear train. The manufacturer thus is able to standardize the head stock and may alter it to provide the required number of speeds to suit customer requirements. The present structure follows generally the principles disclosed in this prior patent and is designed to provide speedier and more convenient selectivity and improved performance. |

Pawl and Ratchet Mechanism for Lathe Tailstocks
|
William G. Hoelscher |
Cincinnati, Hamilton County, OH |
Claim:
In setting up a lathe for operation, it is necessary to adjust the tailstock center longitudinally so that the work may be engaged between the head and tailstock centers. Where the variation in work length is slight; the tailstock center may be adjusted longitudinally relative to the tail stock to engage the work. When the variation is greater than the adjustment range of the center however, it is necessary to shift the tail stock bodily to a position approximating the end of the work and the center then is adjusted to establish the bearing engagement. To permit tailstock adjustment, the tailstock is mounted slidably upon the bed and clamping means are provided to clamp it in selected position. In conjunction with these clamping devices, it is customary to provide a series of ratchet teeth in the bed and to equip the tailstock with, a pawl or similar latching device. to establish a positive lock between the tailstock and bed. This arrangement resists positively the thrust of the work against the tailstock center to, prevent the tailstock from shifting under vibration and impacts. |
