Patent Number	Date	Title	Name	City	Description
70,830	Nov. 12, 1867	Improved tool-rest	William Gleason	Rochester, NY	An 1870 ad for Connell, Gleason & Graham mentions "Gleason's Patent Lathe Rest".

175,859	Apr. 11, 1876	Machine for Cutting the Teeth of Metal Gears	William Gleason	Rochester, NY	William S. Loughborough - patent attorney It is well understood by persons versed in gearing that while the teeth of spur-gears may be correctly formed by the revolving cutters as used in the ordinary gear-cutter, those of bevel-gears can be only indifferently-well formed by the same means. The error in the teeth of bevel-gears cut in this manner is serious, in causing them to "rattle" when run at a moderately-high speed, to "crowd' and run hard and in subjecting them to an uneven wear. It is also well understood that in a correctly-cut tooth of a bevel-gear every line truly drawn along the surface of either face, or the point of the same, or bottom of the space between the teeth, should tend toward a common central point lying in the plane of the axis of the gear. To produce a machine that will thus correctly cut the teeth of bevel-gears is the object of my invention; but it is equally well calculated to cut the teeth from blanks by first grooving the blank around to the proper depth for the spaces, and then giving to the faces of the teeth the desired curvature.
RE9,468	Nov. 16, 1880	Machine for Cutting the Teeth of Metal Gears	William Gleason	Rochester, NY	Frank H. Clement - patent attorney It is well understood by persons versed in gearing that while the teeth of spur-gears may be correctly formed by the revolving cutters as used in the ordinary gear-cutter, those of bevel-gears can be only indifferently-well formed by the same means. The error in the teeth of bevel-gears cut in this manner is serious, in causing them to "rattle" when run at a moderately-high speed, to "crowd' and run hard and in subjecting them to an uneven wear. It is also well understood that in a correctly-cut tooth of a bevel-gear every line truly drawn along the surface of either face, or the point of the same, or bottom of the space between the teeth, should tend toward a common central point lying in the plane of the axis of the gear. To produce a machine that will thus correctly cut the teeth of bevel-gears is the object of my invention; but it is equally well calculated to cut the teeth from blanks by first grooving the blank around to the proper depth for the spaces, and then giving to the faces of the teeth the desired curvature.

3,521,524	Jul. 21, 1970	Control Apparatus for Checking and Controlling Sequential Machine Operations	Ernst J. Hunkeler	Fairport, Monroe County, NY	Cushman, Darby & Cushman - patent attorneys ABSTRACT OF THE DISCLOSURE A work loader and transfer device for handling and moving gear blanks and gear pieces from one station to lg another in a gear cutting apparatus is disclosed. The work loader and transfer device is constructed to operate between at least two cutting or working positions of a machine and includes means for being lifted and lowered as well as rotated back and forth about a vertical axis of rotation. Work holding devices are positioned on the ends of arms associated with the work loader and transfer device, and more than one type of work holding device may be associated with a single work loader and transfer means. Each work holding device includes a centering cup means for contacting a gear piece and for centering the same relative to the work loader and transfer device, and jaw members are provided for affecting a tight grip of the workpiece. Means may be provided for rotating or indexing the workpiece relative to the loader and transfer device so that the workpiece is properly oriented for a cutting operation. A control system is provided for checking and controlling a sequence of operations of a machine, and the control system may be combined with the work loader and transfer device to effect its sequential operations. The control system includes means for taking air read-outs of various functions of a machine to detect a failure of any given function in a sequence, and the control system includes means for shutting down automatic operation of a machine if such a failure occurs. In addition, a checking device is provided on a bevel gear cutting machine to determine proper stock division and seating of a workpiece after it has been transferred to a work station. The checking device may be included in the control system so that improper positioning of a workpiece will result in a shutdown of handling operations for a gear-cutting machine. Also, a method for handling work blanks and workpieces between two or more stations of gear cutting apparatus is described.

7,651,383	Jan. 26, 2010	Method of Lapping Gears	Hermann J. Stadfeld	Webster, NY	Robert L. McDowell - patent attorney SUMMARY OF THE INVENTION The present invention provides a controllable gear lapping process whereby the lapping process may be modified at discrete locations on the tooth surface in order to selectively modify the tooth flank surface. The inventive method of lapping a gear set having first and second gear members comprises defining a plurality of grid points on the tooth flank surfaces of each of the first and second gear members. A lapping correction is determined for more than one, preferably all, of the plurality of grid points with the lapping correction defining an amount of lapping at each of the more than one of the plurality of grid points whereby an amount of stock material is removed at each of the more than one of the plurality of grid points and wherein the amount of stock material removed at each of the more than one of the plurality of grid points is dependent upon the magnitude of the lapping correction at the respective each of 5 the more than one of the plurality of grid points. The gear set is lapped by rotating the first gear member in mesh with the second gear member in a manner such that contact between the members is shifted from at least a first grid point to a second grid point whereby lapping contact is maintained at 10 each contacted grid point for a time sufficient for removal of the predetermined amount of stock material at each respective contacted grid point. amount (e.g. 10 microns) of material) followed by a reduced time 3 point sweep lapping cycle.
