Abstract

632,935. Percussive tools. MATTESON, S. E. A. Sept. 27, 1946, No. 28922. Convention date, Nov. 14, 1945. [Class 124] In a percussive tool, the drill steel 4 extends the whole length of the tool and an annular piston 2 strikes against a displaceable ring 7 surrounding and co-operating with a clamping device 3 on the steel. The device 3 has a conical or wedge-shaped outer surface, may be secured to any point on the steel, and may be released by striking the underside of the ring 7 or by admitting compressed air below the piston 2.
