Abstract

298,886. Neville, C. July 3, 1928. Percussive drills.-A spraying device for rock drills comprises a compressed air conduit C, Figs. 1 and 3, outside the drill trunk having a branch 7 to direct a portion of the compressed air and carrying an air jet 8, Fig. 3, surrounded by a chamber 10 having a water inlet 11 and a nozzle 9 to direct the spray towards the drill and outside the drill hole. The jet 8 and nozzle 9 have a common axle extending at an angle to the axis of the drill so that the spray surrounds the drill outside the drill hole. The ends of the conduit C are provided with screw threads for attachment between the compressed air supply and the drill trunk.
