Abstract
1,065,283. Shaft and pipe couplings. SCHMIDT, KRANZ & CO. G.m.b.H. June 12, 1964 [June 18, 1963], No. 24555/64. Headings F2G and F2U. [Also in Division E1] In rods for mineral drilling operations, individual interconnected tubular sections 1 each have an integral polygonal, e.g. quadrangular, sectioned female coupling part 2 at one end and an axially bored corresponding polygonal sectioned male coupling part 3 protruding from and welded in the other end, respectively, for engagement with the male and female parts of adjacent sections, a spring-loaded snap-pin 8 in each part 3 is engageable with a hole 9 in a mating part 2, and to stabilize and seal each coupling the end 5 of each part 3 is made cylindrical over a length greater than its diameter to accurately fit a corresponding cylindrical bore 6 adjacent a mating part 2 and a sealing ring 10 is provided in a groove in the bore 6 or, as shown, the end 5. The snap-pin 8 is retained by a ring 11 and provided with a sealing washer 12. As shown, a helical smoothing rib 7 is wound round the section and welded thereto at both ends. The drillings produced at the bottom of the borehole may be moistened during drilling to produce a non-flowing slurry which is fed to the borehole mouth by the rib 7. As shown, a small transverse bore 13 may be provided in the polygonal part 3 to permit a controlled small quantity of liquid to be added to the drillings drying out during transportation. Drilling may be initially without flushing medium so that the drillings are moved only by the smoothing rib, a flushing medium such as water or air being used later. The sections of Fig. 4 (not shown) dispensing with the smoothing rib are used where a smooth borehole wall is not needed.
