Abstract

112,028. Rudberg, S. Nov. 18, 1916, [Convention date] Void [Published under Sect. 91 of the Act]. Percussive drills.-In a pneumatic rock drill with two or more pistons acting alternately on the bit, or on an anvil block bearing against the bit, the pistons arc co-axial. In the form shown, the anvil block 3 is struck alternately by an annular piston 5 and a solid piston 6 moving through the annular piston. The piston heads work in separate chambers 7, 8.
