Abstract

356,543. Percussive tools. INGERSOLL-RAND CO., 15, Exchange Place, Jersey City, New Jersey, U.S.A. Oct. 21, 1930, No. 31606. Convention date, Jan. 24. [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 hole in the arm W gripping the rod O fixed to the cradle. This arm is held in an inclined position by the springs h, j, one of which is kept in compression by the spring-pressed plunger engaging recesses on the bar w. Movement of this plunger to the opposite end of the recesses w causes arm W to be oppositely inclined and the tool then automatically withdraws. A stop secured to the cradle, engaging the extension y, automatically reverses the feed at a predetermined position.
