Abstract
355,587. Percussive tools. INGERSOLL-RAND CO., 15, Exchange Place, Jersey City, New Jersey, U.S.A. Oct. 31, 1930, No. 32835. Convention date, Jan. 30. [Class 124.] Feed motions.-The tool A is fed forward by the blow caused by the piston striking the drill, but recoil is prevented by the screw S. A ratchet acting on the head W of the screw enables the screw to rotate when the tool feeds forward but prevents opposite rotation. Two ratchets are provided so that a withdrawing motion can be made similarly a handcontrolled brake acts on shoulder w to prevent too rapid action when the tool is used in a vertical position.
