Abstract

129,175. St. Stephens, R. de H., and Climax Rock - Drill & Engineering Works, Ltd. Sept. 24, 1918. Percussive hand. tools.-In a tool having a disk valve reversed by the compression, the valve box is made in three parts e, f, g having the valve h housed centrally in the part g. The parts e, f are reressed at i, k to provide pressure areas of different areas in communication with the supply. The ports e, f are ported to communicate with the inner and outer ends of the cylinders respectively. The parts e, f, g are held in position by dowel pins.
