Abstract

399,773. Percussive drills. HILLS, F., 45, Airthrie Road, Goodmayes, Ilford, Essex. Sept. 12, 1932, No. 19466/33. Divided on 397,106. [Class 124.] The front end of a percussive drill is provided with a rubber buffer 14 to absorb the blows made by the piston when the steel 11 is withdrawn from the work. The buffer is completely enclosed and can be initially compressed by tightening the side bolts. In a modification the sleeve 10 is screwed on to the tool body 9, and the tool steel is formed with a collar inside the clutch 13 to prevent its withdrawal.
