Abstract

1,273,921. Couplings. MATTHIAS SPENCER & SONS Ltd. 19 April, 1971 [7 Jan., 1970], No. 767/70. Heading F2U. A quick acting coupling, shown applied to a drill bit 17 and rod 19, consists of a threaded stud 18 on the bit and a threaded socket 15 on the rod, the latter having an inclined bore 16 of a diameter slightly greater than stud 18 and passing through the socket threads to enable the stud to be inserted at an angle into the bore 16 to clear the threads and the members to be brought into alignment to engage the threads and then to be rotated through a small angle to lock the bit and rod. The arrangement may be employed to connect the ends of drill rods, Figs. 1-3 (not shown), the stud 18 being a separate element and each abutting rod end having an inclined bore in the threaded socket. Alternatively, the rod ends may have plain threaded sockets and the stud shaped to provide for quick coupling, Figs. 5 and 6 (not shown).
