Abstract
182,846. Maschinenfabrik G. Hausherr, E. Hinselmann, & Co., and Jasper, K. T. Feb. 11, 1921. Percussive tools. - In a compressed-air percussive tool, such as a coal cutting appliance, a separate starting valve is opened by pressing the tool on the work, being closed by the air pressure when the tool is drawn away. In the form shown in Fig. 6, the chamber 31 containing the distributing ball valve 36 is arranged alongside the cylinder 13. The inlet and exhaust conduits, 11 and 12 respectively, are arranged inside a wooden handle 10, and the separate starting valve 21 is opened by the tail 15<1> of the tool by pressing the latter on the coal. Fig. 7 shows a different form of starting valve 65, the cross-sections of the passages on the two sides of the seating being respectively triangular and hexagonal, as shown by Fig. 8. Rods 19, Fig. 3, may be arranged to lift a collar 51. In this form a second ball valve 41 controls the exhaust conduit, and the rods 19 may be replaced by a single member arranged to rise a spring-pressed ball valve situated in the part 23' of the air passage.
