Abstract
674,464. Percussive drills. ATELIERS DECONSTRUCTIONS MECANIQUES ARMAND COLINET. May 19, 1950, No. 12639/50. Class 124. A pneumatic hammer having a jet of atomised water to lay dust during working has a nozzle removably fixed to the tool holder by a clip, and a key engaging the holder and the flattened end of the nozzle, axial movement of the clip and the escape of the key being prevented. As shown, water is supplied from a hose 32 to a chamber 34 in a valve housing containing two valves 5, 5' joined by a stem 35 and urged on to their seats by a spring 33. Compressed air entering the tool handle 1 through a passage 2 acts on a diaphragm 4 to open the valve 5' and allow water to enter a tube 9; at the same time a supply of compressed air enters the tube 9 through a passage 8. The forward end 10 (Fig. 16) of the tube 9 is flattened and is held in a clip 11 surrounding the nose 13 of the tool by a cotter pin 15 which is prevented from falling out by a pin 18. The tube may be released by driving the pin 18 into a depression in the clip. A groove 17 in the nose of the tool co-operates with the cotter-pin to prevent axial movement of the clip. The amount of air admitted with the water may be controlled or entirely shut off by a plug entering the passage 8, Fig. 2 (not shown). Disconnection of the hose 32 allows the tool to work dry.
