Abstract

920,195. Percussive tools; centre punches. MUSTAD MASCHINEN-UND EISENWARENFABRIK G.m.b.H. Dec. 15, 1960, No. 43226/60. Classes 61 and 124. In a spring-actuated tool comprising a spring 5 compressed by downward movement of an outer shell 2, and a striker 4 impelled by the spring on to an anvil 1<11> on the tool holder 1, the striker is held inoperative during downward movement of the shell by balls 8 running along inclined channels 10 in the striker and engaging the end 1<1> of the holder. Towards the end of the downward movement a surface 2<1> on the shell forces the balls into the channels to release the striker. The tool 3 is exchangeable, and the compression of the spring 5 may be adjusted by a cap 6 having a lock-nut 7.
