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 Mfg. 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 Mfg. 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. |

Milwaukee, Milwaukee County, WI |
Morsell, Lieber & Morsell - patent attorneys
Patent 2,260,624 was the subject of litigation: the inventor, Johann, sued the assignee, Milwaukee Electric Tool:
Action commenced by the plaintiff, Albert Johann, against the defendant, Milwaukee Electric Tool Corporation, to recover $10,000 on an alleged oral contract which plaintiff claims he made with the defendant in 1940. He claims that under the terms of the contract, he was to be paid $2 by defendant for every pneumatic-hammer unit manufactured and sold by defendant, which embodied the patented invention of plaintiff, pursuant to an assignment of the patent rights by plaintiff to defendant, but in no event was the amount to be paid by defendant to plaintiff to exceed $10,000. Upon the trial of the action, the court directed a verdict in favor of the defendant, and dismissed plaintiff's complaint upon its merits. Plaintiff appealed from the judgment. (03 Jul., 1953.)
I claim:
1. In combination, a portable C-shaped frame having upper and lower ends, an anvil universally tiltable upon said lower frame end, a hammer cylinder adjustable with respect to said upper frame end toward said anvil, an impact pin protruding from the lower end of said cylinder, a piston reciprocable within said cylinder to deliver blows to said pin, and a dolly block interposed between said pin and said anvil, said block being universally tiltable relative to said cylinder and pin and having an annular groove facing said anvil and providing a peripheral work engaging lip spaced from and surrounding the axis of said pin for effecting simultaneous tilting of the anvil and dolly block.
2, In combination, a portable C-shaped frame having upper and lower ends, an anvil universally tiltable upon said lower frame end, a hammer cylinder adjustable with respect to said upper frame end toward said anvil, an impact pin protruding from the lower end of said cylinder, a piston reciprocable within said cylinder to deliver blows to said pin, and a dolly block interposed between said pin and said anvil, said block being universally tiltable relative to said cylinder and pin and having an annular groove facing said anvil and providing a peripheral work engaging lip spaced from and surrounding the axis of said pin for effecting simultaneous tilting of the anvil and dolly block, and said pin being movable along its axis and relative to said dolly block and anvil.

Abstract:
A method for conducting an operation including a power tool battery pack. The battery pack can include a housing, a first cell supported by the housing and having a voltage, and a second cell supported by the housing and having a voltage. The battery pack also can be connectable to a power tool and be operable to supply power to operate the power tool. The method can include discharging one of the first cell and the second cell until the voltage of the one of the first cell and the second cell is substantially equal to the voltage of the other of the first cell and the second cell. |
