Abstract
279,573. Grant, J. J. Aug. 6, 1926. Percussive drills.-In an underwater or other type of drill the leakage of clearing fluid at the supply end of the central tube 24 is prevented by a packing gland 27 and at the forward end by packing 22. The tube is jacketed by an asbestos sleeve 28, to prevent condensation when the drill is actuated by steam pressure. The twist bar 8 extends backwards through the rear cover 3 into the water chamber 11, part of it being turned cylindrical to fit the packed point 27. The chuck 17 has a recess to accommodate a stem 31 on the drill head, which is bolted to the chuck by means of a flange 29.
