Abstract

119,131. Aktiebolaget Atlas Diesel, and Andersson, G. Oct. 25, 1917. Percussive drills. - In a scavenging device for rock drills, the water supply nozzle 9, held in the bit-holder 5 by a screw gland 10, has a socket 11 containing a packing 12 which bears on a flat on the anvil block 3 to prevent rotation of the latter and on which the water pressure acts to give a tight joint in the socket 11 and against the anvil block.
