Abstract

1,034,537. Fluid-operated mine roof supports. UNIS-FOND S.A. Aug. 12, 1964 [Aug. 13, 1963; May 27, 1964], No. 32810/64. Heading E1E. A mine roof support comprises a bladder 2 inflated by liquid fed from a container 1 under compressed air supplied from a source 6, the pipe connection 3 between the members 1, 2 having a combined calibrated relief/ release valve 4, 5 therein. The bladder is made of india rubber and provided with roof engagement ribs 2a and a shield 8 consisting of wheels or rollers linked together. The bladder may consist of two parts interconnected by a bolted frame construction for details of which Figs. 2, 3a-3d (not shown) should be referred to. The container may support two bladders or be arranged in superimposed relationship therewith for details of which and other minor modifications Figs. 4-10 (not shown) should be referred to.
