Patent Number Date Title Name City Description
D59,678 Nov. 15, 1921 Design for an electric drill Arno H. Petersen Milwaukee, WI This is the innovative Petersen "Hole Shooter" drill, introduced in 1922 in response to Henry Ford's request for a compact, light-weight and portable ¼" electric drill. The Hole Shooter, the first electric drill that could be held in one hand, weighed about 5 pounds and used a Westinghouse series-wound motor. A fire destroyed the A. H. Peterson Manufacturing Co. plant and Petersen sold the rights to this drill to his business partner, A. F. Siebert, who then founded the Milwaukee Electric Tool Corp. in 1924 and then produced Milwaukee branded Hole Shooters. Nearly a century on, Milwaukee remains a major force in handheld power tools.
The US Patent Office Trademark serial number 136,911, filed 1920-09-07, was granted to A. H. Petersen Mfg. Co., Milwaukee, for the "HOLE SHOOTER" logo where the letters are made up of lots of little black circles.
In 1919, Herb Tautz (future founder of Delta Manufacturing Co.) was a designer for A. H. Petersen Mfg. Co., so he likely had a hand in designing the Hole Shooter, although his name does not appear on the patent. By 1920 Tautz was working for Briggs & Stratton.
