Abstract

221,451. Rice, J. V. June 5, 1923. Percussive drills.- In a percussive tool actuated by internal combustion, particularly of the kind described in Specification 221,270, the ignition of the charge causing the return stroke of the piston is effected by a spring-mounted rod 41, which moves forward by its own momentum at the moment of impact and completes the ignition circuit through a contact 39.
