Abstract

123,460. Spencer, A. L. Hitchcock-, and Sharman, P. A., (trading as Spencer & Co., W. H.). May 13, 1918. Percussive drills; percussive channelling-drills. -In a column for supporting rock drills, coalcutting machines, &c. and for other purposes in which ratchet gear actuates a nut to operate the adjustment screw, a loching-pawl l, held in or out of action by a spring m, engages teeth b<1> on a fixed part b of the column a to prevent the screw c from moving inwards due to vibration. The nut d is operated by a reversible pawl h which, with the pawl l, is mounted on a pin j in a case g porvided with a socket g<1> for a handle. A removable cover f gives access to the pawls &c. A feather e<1> prevents rotation of the screw. The base o is detachable from, and wider than, the column a and is connected to a fixed plug p by a tongue and groove joint and a bolt q.
