Abstract
728,489. Percussive drills. CANADIAN INGERSOLL-RAND CO., Ltd. Aug. 17, 1953 [Jan. 30, 1953], No. 22643/53. Class 124. A connection for a drill steel and bit comprises a tubular coupling member having tapered sockets for frictional connection with the tapered ends of the steel and the bit, and having an outside diameter only slightly less than the maximum diameter of the bit and acting as a bearing for the steel. The diameter of the coupling may be 85 to 95 per cent of that of the maximum bit diameter. As shown, a tubular coupling 13 has tapered sockets 14 and 19 which engage tapers 16 of a bit 12 and 20 of a steel 11 respectively. Shims 22, e.g. of copper, may be inserted in the sockets to assist in the easy disengagement of the parts. The taper of the sockets may be such that the included angle is between six and seven degrees.
