Abstract
1367711 Rod couplings SANDCO Ltd 6 Jan 1972 [7 Jan 1971] 537/72 Heading F2G Drill rods, which are coupled by means of a sleeve 12, have spaced screw-threaded portions, each having a tapered contact surface, to abut a ridge 15 in the sleeve. Thus, when the terminal threads 20, 20a become worn, they may be cut off, so that the next portions 10, 11 can be screwed into the sleeve. Preferably, when the ends of the rods abut in the sleeve, only one of the contact surfaces engages the complementary ridge 15, so that percussive forces are transmitted directly through the rods and not through the sleeve. Multi-start screw threads may be employed.
