Abstract
1,134,552. Advancing mine roof supports. GEWERKSCHAFT EISENHUTTE WESTFALIA. 30 Sept., 1966 [2 Oct., 1965], No. 43807/66. Heading E1E. In an advacing mine roof support assembly consisting of three frames arranged in parallel each frame is interconnected by separate shifting devices 7, 9 to a transverse floor beam 6 and a transverse roof beam 8, respectively, pivotal connector 6', 8' allowing a degree of misalignment. Alignment jacks 10, 11 are also disposed between adjacent frames. The roof bar may be of articulated construction and have its end section presented towards the conveyor supported by an inclosed prop, see Figs. 3 and 4 (not shown); guide means being provided for the transverse roof beam. In a final modification, Figs. 5 and 6 (not shown), the transverse roof beam consists of hinged sections each of which is supported by an inclined prop, guided in the roof beam of its associated frame and advanced by an underslung jack.
