Abstract

1,159,495. Self-advancing mine roof supports. GULLICK Ltd. 23 Nov., 1967 [23 Dec., 1966], No. 58353/66. Heading E1P. In an advancing mine-roof support assembly comprising two frames, see Fig. 1 .(not shown) arranged in .parallel and interconnected by a parallel .arrangement of pivotal, links 24, 25 for alignment purposes, advancement is effected by a ram having interconnected pistons 30, 31 working in opposed cylinders. 28, 29 which are pivotally connected to one of the links 25 and .to a conveyor C respectively as shown. Control of the supply of pressurefluid to the props and ram of the assembly or a series of such assemblies is effected by striker valves positioned at. the ends of the cylinders and actuated by their pistons.
