Abstract

647,023. Percussive drills. ATLAS DIESEL CO., Ltd., and EMMS, J. D. May 27, 1948, No. 14351. [Class 124] A pneumatic pick comprises an automatic water pressure controlled air valve, which interrupts the air supply if the water pressure falls below a predetermined value, connected to the pick by tubing, and air and water control valves in the pick operated by a single trigger. As shown, air and water enter an automatic valve by connections 8 and 7 respectively, the water passing into a chamber 9 and acting, if under sufficient pressure, on a diaphragm 10 to open a spring-closed ball valve 12 thus allowing air to pass to an outer hose 15 while the water passes through an inner hose 16. An air valve 25 controlled by a trigger 26 in the tool handle 18 admits compressed air to operate the tool and also to open a ball valve 20, fitted in a housing between the handle and the body of the tool, and admit water to sprayers in the nose of the tool. The automatic valve may be situated some distance, say 6-10 feet, from the pick.
