Abstract
601,555. Percussive tools. HOLMAN BROS., Ltd., and ARTHUR, J. Nov. 9, 1945, No. 29949. [Class 124] In a pneumatically-operated colliery pick, the throttle valve 15 controlling the supply of compressed air to the pick is coupled to a spring-loaded valve 19 controlling the supply of liquid to a spraying device 6, 7. When the valve 15 is opened by a control button 16, it moves a spring-loaded rod 17 attached to a diaphragm 18 separating the two valves, and liquid from an inlet fitting 14 passes through passages 12, 9, 8 provided with sealing devices 10, 11, to the annular nozzle 6 which surrounds the steel 4 and is provided with a number of differently inclined spraying holes 7.
