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
294,673	Mar. 04, 1884	Grinding-mill	Ezra Rhodes	Cleveland, OH	Co-assignee was partner in W. R. Eynon & Co., which manufactured this mill and which eventually became Ingersoll Milling Machine Co.
338,221	Mar. 16, 1886	Grinding-mill	William R. Eynon	Cleveland, OH	This feed grinder was manufactured by W. R. Eynon & Co., which became Ingersoll Milling Machine Co.
23,785	Apr. 08, 1886	Grinding mill	William R. Eynon	Cleveland, OH	This feed grinder was manufactured by W. R. Eynon & Co., which began making milling machines and became Eynon & Ingersoll and then Ingersoll Milling Machine Co.

		Milling-Machine	George W. Smith	Rockford, Winnebago County, IL
804,778	Nov. 14, 1905	Yieldable Gear	George W. Smith	Rockford, Winnebago County, IL	Improvement in "yielding gears...capable of transmitting motion which is positive under normal conditions and yet is capable of a release in the event of obstruction, a matter which is very essential in the operation of certain machinesâ€”such as, for instance, as milling-machines." A gear is driven by a hub that transmits the rotation through a beveled sleeve; a stiff spring pushes the beveled surfaces together but allows them to slip when excessive force is applied. The compression of the spring is determined by the relative position of a second sleeve inside the first sleeve, the two sleeves being coupled by screw threads. Threading the second sleeve further into the first sleeve increases the spring compression. This mechanism allows for momentary slippage as sometimes needed when shifting gears.
856,662	Jun. 11, 1907	Face-mill grinder	George W. Smith	Rockford, IL	"The object of this invention is to construct a machine for grinding the knives of a milling-machine, and in which the knives are ground from their cutting edge toward the heel..."
991,100	May. 02, 1911	Milling-machine	George W. Smith	Rockford, IL	This patent date was seen in an Ingersoll Milling Machine Co. catalog for their No. 2 Heavy Duty Ingersoll Miller, available in both vertical and combined versions. The same patent date is seen in that catalog for their Numbers 3 and 5 milling machines, which are both combined models, i.e., knee-type milling machines equipped with both horizontal and vertical spindles.
1,039,075	Sep. 17, 1912	Face-Mill Grinder	George W. Smith	Rockford, Winnebago County, IL	Witness A. O. Behel was a patent attorney, with his office at 116 S. Main Street in Rockford; in 1880 Jacob Behel was a patent attorney and mechanical engineer at that address and A. O. Behel was a mechanical draughtsman, no work address given.
1,066,764	Jul. 08, 1913	Variable-Speed Gearing	George W. Smith	Rockford, Winnebago County, IL

1,094,940	Apr. 28, 1914	Milling-Machine	George W. Smith	Rockford, Winnebago County, IL	This horizontal milling machine drives both ends of the cutter holding bar.
1,128,274	Feb. 09, 1915	Slideway Construction	John B. Sinderson	Rockford, Winnebago County, IL	Sliding carriage for milling machine or boring machine that is designed to minimize side forces on the slideways of the bed.
1,139,422	May. 11, 1915	Milling-Machine	John R. Johnson	Rockford, Winnebago County, IL	Further improvements to horizontal milling machines that drive both ends of the spindle, as in patent 1,081,932. The improvements are aimed at avoiding problems when a pair of cutters are mounted, one close to each end of the cutter bar, and there is an interrupted cut where one of the cutters has no work to do for a portion of its horizontal travel. In addition, a mechanism is provided to distributed power equally to either end of the bar regardless of any small misalignment of the drive mechanisms on either end.

1,188,339	Jun. 20, 1916	Milling-machine	John B. Sinderson	Rockford, Winnebago County, IL	"This invention relates in general to milling machines and has more particular reference to those of the knee-type in which the frame is shaped to provide an overhanging or projecting head for supporting a vertical cutter-holding spindle in addition to the customary horizontal spindle journaled in the upright portion or frame proper of a milling machine. The primary object of my invention is to provide a milling machine in which an angular face or a sharp corner may be milled in one operation by a pair of face milling cutters each of which shall mill a surface of a width substantially equal to its face diameter."
1,208,852	Dec. 19, 1916	Adjusting Cutter	William C. Sproul	Rockford, Winnebago County, IL	"...The liability of error in the adjustment of one cutter head is, of course, multiplied when the machine comprises a number of cutter heads arranged to operate upon a single surface, as, for instance, when the mahine is used to mill the top of an automobile crank case, the cutters being set to produce by their conjoint action and absolutely flat surface. My present invention aimed to provide a method of adjustment by which the cutters may be adjusted with absolute accuracy and precision to produce perfect results on the articles operated upon."
