Abstract

748,090. Earth-boringapparatus. SJOSTROM, A. June 18. 1953 [Dec. 23, 1952], No. 16923/53. Class 85 In a percussion rock-drilling machine the bit-supporting cable 2 is connected to a wirich drum 30 driven intermittently from a continuously rotating shaft 24 through a clutch 23 26 that is disconnected by a pin 29 on a constantly rotating disc 28 acting on a disc 27 secured to the spring-biased part of the clutch 26.
