Abstract

391,099. Spring hammers. SCHIELE & BRUCHSALER-INDUSTRIEWERKE AKT.-GES., Baden-Baden, Germany. July 15, 1931, No. 20345. Convention date, July 15, 1930. Void [Published under Sect. 91 of the Acts]. [Class 124.] In a spring hammer wherein a striker d is actuated by a crank f through springs b<1>, b<2>, the springs are so designed as to eliminate recoil. The Specification, which does not admit of satisfactory abridgment, contains an explanation of the mathematical relationship between the " constants of the spring mechanism and the blow elasticity " requisite to effect this purpose. The length of the part m of the tool is made such that the striker at rest is in contact with the end of the tool shank when the crank is in its mid position, as shown.
