Abstract
19,535. Hamor, J. M. Sept. 27,1904, [date applied for under Patents Act, 1901]. Rock drills.-A rock drill or other impact tool, specially designed so as not to require skilled labour in the assemblage of its parts, has a cylindrical valve n with exhaust and symmetricallyarranged inlet ports 19, 14, 15, and a recess 16 for a fixed piston or abutment r which also limits the oscillatory movement of the valve. Motive fluid enters the main cylinder d by the pipe q, passages 10, 11 in the valve-chest covers m, and ports 12, 13 and 20, 21, and exhausts through the ports 20, 21, 19, 22, 23, and pipe w. Live fluid is constantly supplied through small passages 17,18 from the parts 14, 15 to the space 16 at each side of the abutment r, the space at either side being connected with the atmosphere by passages 24, 27 or 25, 28 and the groove 26 in the piston c to move the valve n and thus reverse the motion of the piston c. The passages 24, 27 and 25, 28 open into the cylinder d in circumferential alinement at points on opposite sides of the longitudinal centre of the cylinder.
