Abstract

26,177. McKay, P. Nov. 19. Rock drills.-A chuck for a percussive rock drill or other boring-tool consists of a head 2 having a longitudinal bore and an intermediate enlarged chamber. The bore contains bushings 5, 6, made angular to receive the drill 7 and separately driven out by a tool entering one of two inclined holes in the head. The bushing 5 is tapered outward at its inner side to permit of slight lateral movement of the drill, and the end of the head is covered by a removable cap 8 held by pins. The drill has part of its stem inclined, to engage a similar bearing- surface 11 on the clamping-yoke in the enlarged chamber. The yoke has two screw-threaded extensions 12, 17 ; the extension 12 passes through a hole 13 and has a nut 15 and a split spring-washer 16 ; the extension 17 passes through a washer 18 and has a stronger spring 20 between the washer and adjusting-nut 19.
