Abstract
690,531. Percussive drills. SANDVIKENS JERNVERKS AKTIEBOLAG. June 21, 1951 [June.28, 1950], No. 14785/51. Class 124. The leakage of flushing liquid from a drill rod assembly is reduced by providing a resilient sealing means mounted on the ends of the drill rods and engaging with a sleeve surrounding the ends of the rods, the sleeve allowing slight longitudinal movement of the rods and transmitting rotary motion. As shown, two rods having hexagonal ends 3, 6 are inserted in a sleeve 5 of the same section held in position by flat metal springs 9. A resilient, e.g. rubber, plastic, or leather, washer 16 is fitted over the cylindrical terminal portions 18 and 19 of the rods and engages in a groove 17 in the sleeve. Two washers, one on each rod may be provided, Fig. 7 (not shown). In a further modification, Fig. 6 (not shown), the terminal portions of the rods may be frusto-conical and the sealing means may have inturned ends engaging with the peripheries of the end portions. The end portions of the rods may be of any desired crosssection.
