1,686,743	Oct. 09, 1928	Carriage Stop Mechanism for Lathes	Fred C. Dull	Sidney, Shelby County, OH
1,750,555	Mar. 11, 1930	Geared Headstock for Lathes	Wendell E. Whipp	Sidney, OH	Howard D. Smith - patent attorney This invention relates to new and useful improvements in geared headstocks for lathes. It is the principal object of my invention 6 to provide for the headstock of a lathe, a non-clashing change-speed mechanism by which a large number of speeds, for example, sixteen are obtained with a less number of gears, in the present instance, fourteen. All of the spindle speeds are selective and the changes are made while the lathe is in operation, the gears being constantly in mesh and preferably of the helical type so that they may run noiselessly and smoothly. Noise, friction and shock, and gear tooth marks on the work, are thus eliminated, while a constant transmission of power is achieved. All changes of spindle speeds are made by a small number of levers, in this instance four, which move double-sided heavy jaw-clutches along multiple integral portions of the spindle and intermediate shafts into locking engagement with the gears in the oil tight headstock, no gears being carried in the cover plate. The advantage of sixteen speeds for the spindle over a less number of speeds is that the operator will have available a more nearly correct spindle speed at which to operate the lathe. Furthermore, with sixteen speeds a more perfect progression of speeds results with a smaller gap between each speed. These results are also accomplished without interlocking devices in the head, thus avoiding complications and unnecessary expense.
1,929,269	Oct. 03, 1933	Apparatus for Automatic Form Turning Lathe	Clifford A. Bickel	Sidney, OH	Toulmin & Toulmin - patent attorneys Our invention relates to an apparatus and method of operation for automatic form turning lathes. It is the object of our invention to provide an automatic relieving machine and method of operation thereof and method of forming work pieces of various sizes and forms, and particularly forming relieved milling cutters. It is the object of our invention to provide such a machine in which the movement of the tool in imparting the configuration to the work piece by the longitudinal and transverse movements of the tool will be automatically, electrically controlled by the engagement and relative movement of a former pin with respect to a template so that the movement of the former pin will make and break electrical contacts which will, in turn, control the longitudinal and transverse movements of the tool with respect to the work. It is a further object to provide for the continuous spiral cut of the tool with respect to the work without the removal of the tool from the work except as it may be necessary, in the case of forming milling cutters with hooked teeth, to readjust the position of the tool and to compensate its position due to the change in angularity of the gash in the work piece and change in diameter thereof. It is a further object to provide means of continuously and uniformly operating the work piece on the spindle at a uniform speed while automatically in synchronism therewith adjusting the point of application of the tool as the tool progresses longitudinally of the work piece so that the tool will always, Upon its return to the work piece, be applied to the leading edge of the tooth being cut, while, at the same time, the path of cutting from beginning to end of the work piece will be substantially spiral and otherwise continuous, as it is possible by the very delicate and minute adjustment of the electrical controls to maintain the tool in substantially continuous contact with a movement of not over a thousandth of an inch with the work piece so that a spiral cut can be attained, while, heretofore, the best that could be accomplished in the art was a series of substantially parallel, continuous, circular cuts. It is a further object to provide a mechanism and method by which, when the pin once engages with the former, it will remain in engagement with the former continuously until the work is completed. It is a further object to provide means by which, when a hooked tooth work piece is being relieved, to either use a corrected template or a tilted template. In the event the corrected template is used, which we prefer and which is one of the forms of our invention, the template is not of the precise form of the work piece, but. is so corrected that the pin following such a template will control the application of the tool to compensate in an overhanging hooked cutter for the angular loss of position due to the angularity of the gash in the work piece as the tool progresses along the work piece longitudinally so that the tool, when guided by the corrected template, will always apply itself to the leading edge of each tooth no matter what position in the length of the work piece, so that the tool will be immediately applied in cutting position to the leading edge of such tooth irrespective of the change of angularity of the gash which forms one wall of the tooth of the work piece and compensate for the change in diameter. It is our object to eliminate relative movements between the former and former pin at intervals, which has heretofore been the custom in the art, and to thereby secure a cleaner, more uniform cut and one of very much greater accuracy than has heretofore been possible in form turning and relieving machines. It is our object to avoid all use of forming tools and to form the work by rough cutting on my machine and then finish cutting but all cutting to be done in accordance with the method and apparatus we set forth in this document. It is a further object to provide a tracer or former pin slightly larger, usually from ten to eleven thousandths of an inch, than the tool diameter to compensate for the air gap in the electrical contact points in the electrical control switch which controls the magnetic clutches and motors for imparting longitudinal and transverse movement to the tool to cause it to be applied to the work to give the work the desired configuration. It is our object to eliminate the use of a template of the same form as the work when working on a hooked tooth milling cutter, as the use of such a template leads to inaccuracies and complication in the mechanism, which we can avoid by our mechanism and method of cutting. It is our object to provide constant spindle speed and synchronous relieving of the tool, the movements of which, while constant in length, are timed as the carriage progresses according to the spiral of the teeth on the cutter.

2,154,947	Apr. 18, 1939	Hardening Metal Surfaces	Arthur H. Lloyd	, England	Application in Great Britain, 20 Jun 1936. This patent number was seen on Cincinnati Milling Machine Co. and Thompson Grinder Co. patent plates.
		Hardening Metal Surfaces	Herbert H. Beeny	, England
2,157,948	May. 09, 1939	Hardening of Metal Surfaces	Herbert H. Beeny	, England	Dyke, Calver & Gray - patent attorneys This patent number was seen on Cincinnati Milling Machine Co. and Thompson Grinder Co. patent plates. This invention relates to the treatment of ferrous surfaces such as are capable of being hardened by being locally heated by means of a burner to a high temperature and then immediately cooled. The flame is progressively applied to the surface at a predetermined rate, the arrangement being such that there is not sufficient time for the heat to be conducted away to the interior of the article before the surface of the latter is quenched. The specification accompanying the co-pending patent application of myself and Arthur H. Lloyd, Serial No. 148,752 describes a particularly satisfactory burner and cooler for treating a ferrous (for example, a cast-iron) surface in this way, and also an unproved form of burner. It is now found that in treating the surface of a cast-iron V-rail in this way there is a tendency for cracks to form along the apex of the rail. This is probably due to the fact of the flames, acting on the flanks of the rail, heating the apex of the rail to too great an extent, this resulting in the apex of the rail being hardened to a greater depth than the flanks of the rail. When a V-rail is to be used as an inverted-V-rail for supporting a machine-tool slide, it is unnecessary for its apex to be hardened as the load is taken by the flanks of the rail. The present invention is concerned with the surface-hardening of the operative face of a V-rail, to be used for supporting a machine-tool slide or some other slide, by flame-heating the flanks of the rail and immediately thereafter cooling them, as specified above; and it involves means acting to prevent the apex of the rail from being hardened in this manner so that the hardened flanks of the rail will be separated from one another by a relatively soft surface along the apex of the rail. Preferably the said means includes a jet of water or other cooling medium arranged to impinge on the apex of the rail in the vicinity of where the flanks are being flame heated, the said jet preferably being directed backwardly. Conveniently the cooling medium from this jet is delivered at a higher pressure than that from the main jets.

2,309,299	Jan. 26, 1943	Method of and Apparatus for Correcting the Lead Error of Screw Threads	Clifford A. Bickel	Sidney, OH	Taulmin & Taulmin - patent attorneys It is common knowledge that most lead screws in lathes, grinding machines and other machine tools vary more or less in lead throughout their length, and that although these variations may be relatively small, they will be translated to and appear increased in lead screws generated on such machines. Various devices have been designed to cope with this difficulty but the results have not been fully satisfactory since lead errors in thread chasing not only result from inaccuracies in the master lead screw but are due to many variable factors such as temperature variations changes in the material to be chased and deflections caused by work stresses and strains between the work and the cutting tool and between the various moving and guiding parts. It is an object of the invention to provide a lead error correcting device which is simple in operation and construction and easily attachable to a machine tool without impeding the work to be done on said machine tool. Still another object consists in the provision of a lead error-correcting device, which will allow This invention relates to thread chasing, and in particular to means for correcting lead errors in thread chasing of every lead error being corrected while or before the finishing cut is made on the thread to be chased. It is a still further object of the invention to provide a lead error correcting device which will be operable to move the lead screw of the machine tool on which the thread is chased in accordance with the lead errors appearing in said thread, for correcting said errors. It is another object of the invention to provide a lead error correcting device as set forth in the preceding paragraph, in which the movement of the lead screw of the machine tool is translated to indicating means to enable control of the lead screw movement.

3,999,665	Dec. 28, 1976	Method and Apparatus for Handling a Coil	John W. Rogers	Shaker Heights, Cuyahoga County, OH	Abstract The handling of metal coils, such as coils of sheet steel, aluminum or other materials is facilitated through the use of a transfer bar which is inserted in the coils before they are removed from a rewind mandrel. In a typical operation the transfer bar is inserted between the inside diameter of the coil and the outside diameter of the rewind mandrel adjacent the coil tail after the mandrel has been collapsed. The transfer bar is then raised into engagement with the coils, contacting them adjacent their tails, and the coils are thereafter carried by the transfer bar as they are moved from the rewind mandrel to a turnstile horn and from the turnstile horn to a downlayer. As a result, removal of the coil tails from the mandrel gripper slot is facilitated, eliminating telescoping of the coils upon removal from the mandrel, and damage to the inside diameters of the coils is obviated because there is no sliding of the coils along the mandrel or turnstile horn after they are carried by the transfer bar. Additionally, damage that often occurs to the coil edges is eliminated because separation between the coils is maintained as long as they are carried by the transfer bar and because separation is maintained, there is no interleaving of the edges of adjacent coils, thereby avoiding the problem of prying adjacent coils apart once they have become interleaved.

4,856,153	Aug. 15, 1989	Spindle Mechanism	Nagle V. Gusching	Sidney, Shelby County, OH	Abstract A spindle mechanism is capable of rotating for a rotative tool and is capable of being locked for mounting a nonrotative tool. First and second curvic couplings may be forced into engagement by a large hydraulic force which concurrently unloads a combined thrust and radial bearing at the outboard end of the support. This permits the spindle, when mounting a nonrotative tool, to be rigidly supported in a nonrotative condition. A smaller hydraulic force may be utilized to move the spindle axially inwardly which disengages the first and second curvic couplings and preloads the combined thrust and radial bearing providing a properly preloaded rotational mode of support when the spindle is mounting a rotative tool. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.

5,421,535	Jun. 06, 1995	Method and Apparatus for Automatically Winding Scrap Metallic Strip Material	Dave P. Hemmert	Wapakoneta, Auglaize County, OH	Abstract: A method and apparatus for automatically winding ribbons of edge trim metallic scrap into a compact ball generated by a side trimming machine including a scrap collection pit located behind the side trimming machine, a conveyor system for transporting the metallic scrap from the collection pit to a winding machine having a tapered mandrel around which the metallic scrap is wound. The scrap winding machine further includes an ironing roll which compacts the metallic scrap as it is wound and a ball ejection means which removes the compacted ball from the winding machine. The conveyor system includes a first sheave and cable system located in the collection pit and a second sheave and cable system extending at an incline from the pit to the winding machine. The sheave and cable systems include a plurality of spring loaded drag hooks for engaging the metallic scrap. The winding machine further includes a parting shear located on an edge of a trailing door which severs the ribbon as the trailing door is closed. The system further includes a hood attached to the side trimming machine for deflecting the trimmed metallic scrap into the collection pit. The entire system is fully automated and can be operated without human intervention.
