Abstract
265,043. Holman, P. M., and Holman, A. T. April 28, 1926. Percussive drills.-The axial rotation of the drill steel 13 is effected by a rod 16 surrounding the water tube and rotated by a suitable motor (not shown). The rod 16 engages with the steel by a squared or polygonal part 17, or a screw thread 47, which may be interrupted. In the case of a screw-threaded connection the front end 117 of the rod may be shaped so as to form an air seal. In both cases a vent 20 is provided. Where a retaining key 112 is used in the chuck, it is shaped so as to be rotated by the wings 113 on the drill steel. An anvil block may be inserted.
