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.
