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.

A 1919 advertisement for handheld electric drills and grinders from Independent Pneumatic Tool Co. carries the phrase, "Licensed Under Burke Universal Motor Patent". A condensed catalog for Duntley (a brand for Chicago Pneumatic Tool Co.) shows their "Universal Electric Drills". "This type of tool is fully covered by letters patent granted February 18, 1913."
