Abstract

21,670. Kimber, W. E. Sept. 24. Sharpening rock drills; power hammers.-In a pump-piston hammer for planishing or finishing the points of rock drills after sharpening, and for other purposes, the hammer cylinder 6 is mounted on the pump cylinder 1, and the ends of the latter cylinder can be opened to the atmosphere to stop the hammer 7. This is effected by a valve 13, Fig. 3, operated by a treadle or hand-lever, or the die 8, Fig. 1, is so arranged that, when not pressed in by the work, it is forced out by a spring 15 to uncover ports 4<Î>, 5<Î> leading to either end of the compressor. A port 16 leading to the atmosphere, which cannot be closed by the die 8, serves to connect the uncovered ports 4x, 5<Î> to the atmosphere or allows the escape of air between the hammer 7 and die 8.
