Abstract
200,303. Thurston, F. W. May 23, 1922. Percussive drills. - A percussive drill has a shock absorbing part, such as a sleeve 12 of chrome nickel steel, between the bit and the shank, which are constructed respectively of wear-resisting material such as chrome vanadium steel and anti-fatigue material such as vanadium steel. The sleeve is made with ribs 66, the grooves between the ribs acting as conduits for debris. The screw threads of the different parts aro made truncated for ease of disconnecting. The sleeve 12 may be welded or otherwise joined to either of the other parts or may be made as shown in Fig. 5. The bit has one or more cutting edges.
