Abstract

631,099. Percussive tools. COLLINS, H. Oct. 22, 1945, No. 27674. [Class 124] [Also in Groups XXI and XXII] Rotary cutters 1 adapted to bore overlapping holes are supported in a mounting 6 of such width that it can enter the resulting slot; the cutter spindles are splined to bevel gears 9 driven by bevel gears 8 on a cross shaft 7, adjacent cutters rotating oppositely. Cams 11 are provided on the shaft 7 to give a percussive action to the cutters against the action of springs 13.
