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
62,998	Apr. 27, 1899	Wrench	Adin Phillips Joy	New Market, NH	Canadian patent for the Joy Wagon Wrench; corresponding U.S. patent 598,319 was granted February 1, 1898.
632,724	Sep. 12, 1899	Bottle-filling machine	Emil R. Klemm	Chicago, IL
D33,374	Oct. 16, 1900	Design for a lifting-jack casing	Emil R. Klemm	Chicago, IL
806,815	Dec. 12, 1905	Wrench	Emil R. Klemm	Chicago, IL	The wrench is of the type with a screw adjusting jaw, and an eccentric clamp within the movable jaw to clamp the wrench to the wagon axle nut. Improved by Klemm's Dec. 17, 1907 patent (no. 873,868). The wagon axle nut wrenches marked INTERNATIONAL MFG. CO. and W. E. PRATT of Chicago and marked "PATENT PENDING" or with this patent date also show the features of patent no. 873,868.
873,868	Dec. 17, 1907	Wrench	Emil R. Klemm	Chicago, IL	The adjusting screw sets the size; the eccentric clamp tightens the jaws. This patent together with Klemm's Dec. 12, 1905 patent (no. 806,815) was used for the International Wagon Nut Wrench. William E. PRATT of Chicago also produced the wrench, marked with the Dec. 12, '05 patent date. See photo accompanying entry for patent no. 806,815.

917,312	Apr. 06, 1909	Friction clutch mechanism	Emil R. Klemm	Chicago, IL
118,623	Jun. 01, 1909	Grinding machine	William G. Klemm	Chicago, IL	This is the Canadian equivalent of US patent 915,298.
122,094	Nov. 23, 1909	Friction clutch mechanism	Emil R. Klemm	Chicago, IL	This is the Canadian equivalent of US patent 917,312.
1,217,188	Feb. 27, 1917	Braking device	Emil R. Klemm	Chicago, IL	These brakes are "particularly adapted for use on motor trucks and other large vehicles." The inventor began manufacturing such trucks in 1917. They had rear-only brakes that were notoriously ineffective. Production of Klemm trucks stopped in 1918, probably because of wartime shortages; production never resumed.
1,298,068	Mar. 25, 1919	Gas-engine governor and auxiliary air-inlet	Emil R. Klemm	Chicago, IL	This patent governor was seen in a 1921 ad from manufacturer E. R. Klemm. See also patent 1,502,476.
		Gas-engine governor and auxiliary air-inlet	Benjamin T. McCanna	Chicago, IL
1,338,087	Apr. 27, 1920	Anti-skid chain	Emil R. Klemm	Chicago, IL
207,033	Dec. 28, 1920	Wrench	Harry G. Norwood	Chicago, IL	This patent is similar to US patent 1,363,343, granted to the same inventor but not assigned to Klemm. Emil R. Klemm was a Chicago manufacturer of jacks, windlasses, and metalworking machinery, and he is known to have manufactured wrenches as well, though we cannot confirm for certain that he manufactured this alligator wrench.
1,410,193	Mar. 21, 1922	Vehicle	Emil R. Klemm	Chicago, IL	Inventor E. R. Klemm manufactured light trucks between 1917 and 1918. It appears likely that the war caused him to stop production of trucks, and it never resumed.

1,758,080	May. 13, 1930	Governor	Emil R. Klemm Jr.	Chicago, IL	It is not known if the E. R. Klemm Co. manufactured this governor. Their post-WWI years are poorly documented.
