Abstract

17,477. Drinnan, J. July 27. Percussive drills.-In a chuck of the type in which the percussive action tends to tighten the grip on the drill, a ring - shaped piece adapted to slide at an angle to the axis of the drill engages, through a set screw, with an intermediate piece in contact with the drill, the construction enabling the drill to be released without any hammering. The axes of the exterior a<2> and interior a<1> of the socket a are inclined to each other and recede from each other towards the open end of the socket. The ring-shaped piece b slides on the exterior of the socket and engages the intermediate piece c through a set-screw e. The intermediate piece is arranged so that it cannot move longitudinally relatively to the ring-shaped piece b. A liner d may be provided.
