Abstract

370,745. Percussive drills. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.- (Ingersoll-Rand Co. ; 15, Exchange Place, Jersey City, New Jersey, U.S.A.) June 22, 1931, No. 18006. [Class 124.] For drilling deep holes the drill steel 24 is extended by the steel 54 connected by the screwed member 46. To ensure that the weight of these steels shall be transferred to the body 5 of the machine a member 28 rests on the front head 32 and supports the collar 48 through rings 56, the lug 34 preventing rotation of this member. Clearing water to the drill bore 64 enters by the pipe 76, glands 70, 78 preventing leaking into the drill mechanism.
