Abstract

165,708. Nyborg, T. G., and Higgins, M. F. Nov. 19, 1920. Percussive drills.-The removable axial tube 5 which conveys fluid for cleaning the drill point is supported by its rear flanged end in a screw plug 6 so as to be readily withdrawn. The plug 6 and a stud 8 which secures the tube therein are suitably pierced with registering holes for the passage of fluid.
