Abstract

409,319. Percussive drills. CLARK, J., 17, Victoria Road, Netherfield, Nottinghamshire. Oct. 25, 1932, No, 29842. [Class 124.] Means for boring below roads &c. comprises a frame with guides in which move a boring tool and a separate fluid operated hammer, and haulage tackle on the frame for moving the hammer. The device 5 is supported by a cradle 10 with upstanding portions 11<a> on each side of the device 5, the cradle 10 sliding, preferably on rollers 9, in a fixed base 8 with guides 11. The forward end of the device 5 is suspended by a pin 13 from a bracket 14 bolted to the cradle 10. At the front of the base is a guide sleeve 15 for the rods &c. 3. The device 5 is advanced by means of a rope or chain 18 connected to the device or passing over a pulley on cradle 10 to the base, the rope being wound on a drum 17 driven by worm gearing 21 or by ratchet means. The drum 17 and rope &c. 18 may afterwards be used to withdraw the borer from the hole or for drawing pipes &c. through the hole. The hole may also be enlarged by the provision of a larger member similar to the member 2 which is similarly driven through the hole.
