Abstract

152,497. Stevens, C. H. Sept. 17, 1919. Percussive hand tools.-In a percussive hand tool, the tubular throttle valve E, with lateral ports F, has a head G with a transverse hole engaged by the bent end II<1>of a push-rod H arranged in a separate passage and contracting with the trigger K. In a modification, the valve head G has an annular groove engaged by a forked end on the push-rod.
