Title: Pneumatic hammer with tubular slide valve control
IPC: B25D9/16
Filed: 1929-05-06
Abstract: 311,734. Heinz, A. May 15, 1928, [Convention date]. Percussive drills.- A percussive hammer is provided with a tubular slide, valve coaxial with the cylinder bore which during its movement allows fluid-pressure from the rear of the cylinder to pass to the forward end to reverse the piston. The valve may have a flat or annular end to increase its speed, and may be in two parts. The valve r has radial holes 4 and the valve chest has ports 1, 3, 2, leading to the two ends of the cylinder and the exhaust respectively. The cylinder is provided with a passage v to effect the valve reversal by supplying fluid to an annular valve area r<2> when the piston during its downward stroke uncovers a port v<1>. With the valve in the forward position, fluid is supplied to the rear end of the cylinder by ports 1 and the forward cylinder end exhausts through port 5, chamber h, the annular space between the valves and the casing above the ports 4, and ports 2. During the upstroke of the valve, fluid passes from the rear of the cylinder through ports 4, 3 to the forward cylinder end to reverse the piston. During the piston upstroke, the upper end of cylinder exhausts through ports 4, 2. When the ports 4 are closed by the piston, the compression reverses the valve. In a modification, the valve is cup-shaped, or the end comprises an annulus working over a projection at the end of the valve chamber. In these constructions the port v extends to the end face of the cup or annulus. In a modification of the arrangement shown in Fig. 1, a throttle device is arranged to control the exhaust from the rear cylinder space, a separate exhaust being provided for the forward cylinder end. In a modification wherein the valve is composed, of two parts, the parts are thrown rearwardly in succession on the piston passing ports leading to forward faces on the two parts respectively.

The wheels 5 are mounted on arms 3 on the axle 1, and are provided with ratchet.-wheels 8 with which engage lifting-pawls 7 on arms 6 on the axle. The pawls 7 are normally held out of engagement by arms 9 on a rock-shaft 10 actuated by a curved arm 30, a two-part rod 15, and a cam 14. Locking- pawl 12 engaging with ratchet sectors 11 are fixed on a rockshaft 13 operated by arms 36, rods 17, and a cam 16. The cams 14, 16 are fixed on a ratchetwheel 20 operated, step by step, by two pawls 21, 22 on levers 23, 24. The actuating-cord 34 is fastened to the lever 23, and the lever 24 is connected bv a rod 25 with an arm 26 on the axle. A pull on the cord 34 moves the cams 14, 16 through an angle of sixty degrees, and allows the rods 15, 17 to be moved backwards by the weight of the arms 30 and the action of a spring 31 respectively, to bring the pawls 7. 12 into engagement with their ratchets. The frame 2 then rises, and the rod 25 and ratchet lever 24 automatically turn the cams 14, 16 through another sixty degrees. This movement has no effect on the rod 17, but extends the two-part rod 15 against the action of a spring 27. Set-screws 35 on the pawls 7 then strike against stops 32 and release the lifting-pawls 7, which are then again held away from the ratchets 8 by the arms 9 under the action of the spring 27. The frame 2 is held up by the pawls 12, and the lever 23 is drawn back by a spring 38 and cord 39. Another pull on the cord 34 completes the cycle of operations and disengages the locking-pawls 12, thus allowing the frame 2 to fall again. The descent is limited by a chain 37 connected to an arm 26<1> on the axle. According to the Provisional Specification, the cycle may be completed in two successive rotative steps of the cam shaft, each effected by the driver's cord.
