Abstract
315,516. Marks, E. C. R., (Ingersoll- Rand Co.). May 18, 1928. Percussive tools. - For the purpose of using pressure air to clear the bore hole, a handoperated rotary plug valve d mounted in the valve chest is adapted when turned into the position shown to admit air from the main inlet port P by way of ports f, g, to one end of the valve ,chest, so that the valve is held at the opposite end and pressure air passes continuously to the front end of the cylinder and thence to the bore hole. The valve is turned by a lever r and held by a spring plunger w. In the normal operation .of the drill the distributing valve is reversed bv pressure, air from the cylinder acting alternately through passages X, Y, which air afterwards leaks away through ports Z, b, respectively. Plugs U in the ends of the valve chest limit 'the travel of the valve.
