Key to Links for Patent Information

USPTO = U.S. Patent Office . Images of the actual patent can be viewed on the U.S. Patent Office web site but a special TIFF viewer must be installed with your browser in order properly work. More information on how to configure your computer to view these patents can be found at TIFF image Viewers for Patent Images.
DATAMP = Directory of American Tool And Machinery Patents . A sister site to VintageMachinery.org with information on patents related to machinery and tools. A much easier user interface than the USPTO's for finding information on machinery patents.

Patent Number	Date	Title	Name	City	Description
1,998,113	Apr. 16, 1935	Reamer	Ernest E. Anderson	Detroit, MI	Invention is an adjustable reamer that can also be used for heavier cuts.
		Reamer	William H. Fritz	Detroit, MI
2,085,095	Jun. 29, 1937	Rotary cutter	Stanley H. Grattan	Detroit, MI	This is an insert-tooth milling machine cutter-head where the cutters can be sharpened and their position in the head adjusted to maintain the same cutting diameter.
2,135,893	Nov. 08, 1938	Gear cutter	Ernest C. Head	Detroit, MI	This cutter is for making spiral-tooth gears and is not a traditional worm-style hob cutter, but rather is a crown-gear style of cutter. The innovation is a cutter-tooth shape that provides a constant pressure angle from front to back which maintains the correct tooth geometry as the cutters are sharpened. A special machine is required to grind the precise tooth shape: see patent 2,135,894.
2,135,894	Nov. 08, 1938	Machine for forming spiral bevel gear cutters	Ernest C. Head	Detroit, MI	This machine grinds gear cutters with the special geometry covered in patent 2,135,893.
2,207,909	Jul. 16, 1940	Milling cutter	Clarence R. Besaw	Detroit, MI	This helical-blade milling cutter has multiple abutting inserted cutters forming each blade.
2,212,012	Aug. 20, 1940	Cutter	Clarence W. Davidson	Orchard Lake, MI	This patent covers an inserted-blade design for milling, reaming, boring, etc., where each insert has cutting edges on opposing sides.
396,013	Apr. 22, 1941	Milling cutter	Clarence W. Davidson	Orchard Lake, MI
2,270,003	Jan. 13, 1942	Gear cutter	Ernest C. Head	Detroit, MI
RE22,891	Jun. 24, 1947	Gear cutter	Ernest C. Head	Detroit, MI	The inventor was deceased at the time of reissue; the reissue was applied for by the Gleason Works, though the original patent was assigned to Goddard & Goddard Co. of Detroit. Gleason Works made gear-cutting machines; Goddard & Goddard Co. made cutters for such machines.
460,908	Nov. 08, 1949	Cutting tool assembly	William J. Solderbeck	Southfield Township, Oakland County, MI
466,180	Jun. 27, 1950	Cutter and method of forming the same	Emmons A. Goddard	Birmingham, MI
2,583,309	Jan. 22, 1952	Cutting tool	William J. Solderbeck	Southfield Township, Oakland County, MI	Construction of an inserted-tooth cutter in two parts that are joined together by welding. This two-piece construction simplifies the machining of the separate parts and reduces cost.
		Cutting tool	William H. Fritz Sr.	Southfield Township, Oakland County, MI
484,904	Jul. 15, 1952	Cutting tool	Fritz William H. Sr.	Detroit, MI
		Cutting tool	William J. Solderbeck	Southfield Township, Oakland County, MI
2,614,441	Oct. 21, 1952	Cutter and method of forming the same	Emmons A. Goddard	Birmingham, MI	The invention is a slitting saw blade and hub that are designed so that the hub and blade cool at the same rate during heat treating so as to minimize distortion and improve the quality of the cutting edge. These goals are achieved by piercing the thicker hub with regularly spaced grooves or holes.
2,778,924	Jan. 22, 1957	Apparatus and method for producing flat surfaces	John P. Hill	Detroit, MI	The invention is a cutter insert made by electric discharge machining, which produces a cutting edge that is smooth and flat and devoid of cracks or scratches that can be the starting point of a fracture in the edge. In addition, the exact method of production is intended to provide precisely parallel surfaces to minimize the risk of fractures when the insert is clamped into a holder.
2,797,299	Jun. 25, 1957	Method of forming serrations at the back of the blade of cutting elements	John P. Hill	Detroit, MI	This patent was divided from the application that became patent 2,778,924.
3,078,565	Feb. 26, 1963	Magnetic chuck adapter plate	Joseph A. Sanders	Detroit, MI	The invention is a plate suitable for clamping to a magnetic chuck, so that the plate can be machined to accept a ferromagnetic part that is not shaped in a way that can be directly held by a standard magnetic chuck. The innovations primarily relate to a construction that is less expensive to manufacture than previous designs.
3,371,394	Mar. 05, 1968	Cartridge type holder	Dupuis Hubert	Detroit, MI	"A cartridge for cutting inserts adapted to be inserted in a tool holder pocket without lateral extension beyond the side walls of the pocket, and to have all adjusting and clamping devices thereof operable at the exposed outer surface thereof."
3,378,901	Apr. 23, 1968	Milling cutter	Hubert Dupuis	Detroit, MI
