Abstract

16,380. Treglown, W. M., and Noble, W. July 15. Percussive drills.-In a hammer drill or the like having means for the passage of live fluid from the rear of the working piston directly to a hollow drill for removing debris, one or more valves &c. are provided on the exhaust to control the operation of the tool and the flow of the fluid for removing debris. In the tool shown, during the forward stroke, a bar j and ratchet m hold the piston against rotation, and the drill k is thus turned by means of a sleeve nut l. Fluid from the rear may pass through the piston to the tool k to remove debris. By throttling the exhaust, this flow of fluid is regulated, and the operation of the piston is prevented or sc regulated as to rotate the tool only. In tools with several exhausts, a valve may be provided on each.
