Abstract

363,793. Percussive tools. INGERSOLL-RAND CO., 15, Exchange Place, Jersey City, New Jersey, U.S.A. Nov. 20, 1930, No. 35025. Convention date, Feb. 11. [Class 124.] Feed motions.- The tool A is fed forwardly by the blow caused bv piston striking the drill, but recoil is prevented by the arm 0, the edges Q, R of which grip the rod G fixed to the cradle. The arm is held in an. inclined position by the plungers X, W, which are selectively pressed forward by motive fluid supplied to the cylinders S, T, and controlled by a valve. Reversal of the pistons from the position shown causes the arm O to be oppositely inclined and the tool is then automatically withdrawn.
