Abstract
200,761. K÷hlen, J. Nov. 22, 1922. Percussive tools.-In a per. cussive pneumatic tool containing ball or other oscillatory distributing valves, the air is admitted to the cylinder by way of two (or more) passages 12, 13 each with a separate valve 9. Branches of each passage lie in a plug control cock 17, which, when turned into the position shown in Fig. 4, cuts off the passages 12, 13 and admits air to a port 21 near the front end of the cylinder, so that the piston is raised enough to permit the air to escape down the grooves in the piston rod and clear out the bore-hole.
