Abstract
244,224. Marks, E. C. R., (Ingersoll-Rand Co.). Oct. 21, 1924. Percussive tools. - The drill shank D of a rock drill, particularly a stoping drill, the socket J in which it is fitted, and the anvil block C are arranged to move together under the blows of the piston. The inner end Y of the socket fits tightly over the reduced end of the anvil block C, which construction also reduces the leakage of water from the clearing passage U. Water which does so leak into the space Z is removed by means of a passage d, which may act as a drain or as a conduit supplied with pressure air by means of which the water is blown out past the flutes H on the socket. In the latter case the air pressure in the space Z assists in holding the socket J against the anvil block. Where the bore is drilled dry, oil may be conveyed by the air to lubricate the flutes. A cap f is provided to prevent water from running back into the drill head. Rotation of the drill is afforded by an outside handle (not shown).
