Abstract

113,267. Rudberg, S. Feb. 5, 1917, [Convention date]. Void [Published under Sect. 91 of the Act]. Percussive drills. - In a rock drill with two or more pistons moving each in a cylinder chamber to impact alternately on the bit or anvil block, the fluid passages are so arranged that the fluid acts on the pistons according to the compound principle. In the tool shown, having co-axial pistons 5, 6 with heads working in chambers 8, 7, fluid supplied through ports 9, 10 reciprocates the piston 6. As this piston passes ports 12, 11 on its working and return strokes respectively. the fluid passes from the chamber 7 through these ports to reciprocate the piston 5, afterwards exhausting through a port 13.
