Abstract

250,340. Holman, J. L., and Holman, A. T. Jan. 13, 1925. Percussive tools.-The anvil block 3 of a rock drill or like tool is formed with an open passage such as a flat 4 whereby motive fluid may leak from one side of the block to the other. An exhaust port 5 is arranged to allow such fluid to escape, the port being formed between the chuck sleeve 6 and a cylinder bush 7. Water which may accumulate in front of the anvil block can also escape by the port 5, to which the main cylinder exhaust may also be led by a suitable conduit.
