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
425,230 Apr. 08, 1890 Grinding-machine Abraham B. Landis Waynesboro, PA
427,091 May. 06, 1890 Grinding-machine Abraham B. Landis Waynesboro, PA This patent was the genesis of Landis Tool Co.; Abraham B. Landis had been working at Geisler Manufacturing Co. when he developed this grinder, and he left Geisler, apparently with their blessing, to begin manufacture of this grinder. Landis subsequently patented several improvements to his original design, and his line of grinders was very successful.

644,929 Mar. 06, 1900 Foot-stock for grinding-machines Abraham B. Landis Waynesboro, PA "In grinding small cylindrical objects, such as shafts, spindles, etc., in ordinary grinding-machines the heat generated by the grinding sometimes will expand such work until it will 'buckle' or curve slightly, and thus interfere with the operation and prevent satisfactory results. The object of my said invention is to provide a foot-stock for holding one end of such work in which there may be slight elasticity to allow for such expansion without the article buckling..."

883,649 Mar. 31, 1908 Grinding-machine Abraham B. Landis Waynesboro, PA "In the use of glass stoppers in bottles designed for containing liquids charged with gas, it is essential that the seat for the stoppers in the neck of the bottle shall be perfectly true and smooth and also that the stopper shall have a correspondingly smooth surface, perfectly true to fit therein, in order to prevent any leakage of the gas and consequent impairment of the liquid. The object of my said invention is, therefore, to provide machinery for the purpose of grinding the seat for the stopper in the neck of the bottle and also to grind the stopper so that it will fit perfectly in said seat."
883,650 Mar. 31, 1908 Grinding-wheel truer for grinding-machines Abraham B. Landis Waynesboro, PA "In the use of grinding machines for grinding parts having rounded corners, such as journals and crank-shafts with shoulders at one or both ends, it is necessary to have the corners of the grinding wheel rounded to conform to the shape of the corner to be ground and to keep the face and corners of said wheels properly dressed..."

1,681,793 Aug. 21, 1928 Flexible coupling Amos P. Steiner Waynesboro, PA This flexible coupling consists of a pair of plates, each with a circle of pins, so that the circle of one set of pins fits completely within the circle of pins on the other plate. Then a rubber or leather band is snaked sinusoidally around the pins, providing the flexible coupling between the plates. This invention has been seen on various woodworking machines, and has also been seen in a catalog from the S. A. Woods Machine Co., labeled as the Woods Flexible Coupling.
