Abstract

329,237. Gamble, S. L. Aug. 21, 1929. Percussive tools. - A silencing chamber for a pneumatic road-repairing drill or other fluidoperated percussive tool is shaped to fit the expansion chamber and is attached by metal bands 12, or by fitting between the side belts, one or more inlets 4 being provided to register with the exhaust ports of the drill. The silencer is fitted with baffles 7 and is tapered downwardly, ending in a curved plate 11 which directs the outflow towards the drill for cooling purposes. -
