Abstract
170,009. D³sterloh, G. Oct. 11, 1920, [Convention date]. Percussive drills.-The grooved twist-bar g attached to the piston e of a pneumatically-operated drill or the like engages a nut h' formed with a coned face adapted to be pressed into engagement with a part i of the casing during the return stroke of the piston by the passage of driving fluid through a duct p. The piston is thus made to turn, and with it the sleeve l carrying the tool. On the working stroke the nut h<1> is pressed away from the part i by fluid transmitted through a duct o; the nut h<1> then turns freely. The nut h<1> may be operated by a spring instead of by fluid pressure.
