Abstract

24,390. Riley, W. K. Nov. 2. Percussive drills.-In a percussive drill having means operated by fluid pressure tending to advance the drill upon a frame, friction means operated by pressure fluid from the same source prevent such advance until the piston imparts a jar to the cylinder owing to the drill striking with insufficient force. The cylinder 7 slides on a frame 5 and is connected to a piston 61, which works in a cylindrical part of the frame, and behind which pressure fluid acts to press the drill forwards. Movement is normally prevented by a pinion 70 engaging rack teeth on the piston 61, the spindle of the pinion 70 carrying a band brake 76 actuated by a piston 80 pressed by fluid admitted through a port 83. The friction may be adjusted through a screw 82<a>. When the drill does not strike with sufficient force, the piston 17 strikes a buffer 33, and the cylinder 7 moves forward. A manually - releasable spring catch prevents rearward movement. A push-valve 103 admits fluid into the piston 61 through a stationary piston-rod 100 to move the cylinder 7 rearwards. The cylinder may be moved by hand through the pinion 70 and rack. A rifled pump-rod on the piston 17 forces water through the piston to the tool, and is also employed to rotate the tool.
