Abstract
751,596. Percussive drills. BAYLISS, JONES & BAYLISS, Ltd. Oct. 20, 1954 No. 28882/53. Class 124 A support for a drilling machine comprises a cylinder and a ram arranged so that the ram may be moved endwise to increase or decrease the length of the support, one end of the support carrying a drill and the other end a ground engaging spike, and a reservoir chamber communicating with the cylinder to form a closed self-contained hydraulic system, the chamber containing a piston movable by manual means in one direction to expel hydraulic fluid into the cylinder to extend the support and in the other to contract the support. As shown, a cylinder 11 has a spike 13 on one end and a guide 10 on the other through which passes a hollow ram 12 supporting a rock drill 18 on its outermost end. The inner end of the ram 12 has a cap which is an easy fit in the cylinder 11. A reservoir chamber 22 is secured to one side of the cylinder and is provided with a piston 28 which is movable by means of a handwheel 31 and screw 29, movement of the piston increasing the length of the support by hydraulic pressure or allowing the support to contract by the reduction of that pressure. The piston 28 may have a larger area than that of the ram and the velocity ratio between the piston and the ram may be 45: 1 to 20: 1. The reservoir chamber is secured to that part of the support which is normally stationary or it may be situated at a point remote from the support and connected thereto by a flexible pipe-line.
