Abstract

469,926. Percussive drills. SIEMENSSCHUCKERTWERKE AKT.-GES. Nov. 24, 1936, No. 32194. Convention date, Nov. 25, 1935. [Class 124] The housing of the electric motor 12 is mounted directly on the casing 11 of the percussive tool, the main body of which is in one piece with the handle 29. The control switch 20 mounted in the handle is manipulated by a short trigger 38 so that the main grip of the handle on the handle is unaffected during switching. The motor shaft has a spur wheel 17 on its end which engages the wheel 18 supported between bearings 20, 21 and rotating a crank 23. The motor is cooled by the fan 33.
