Abstract
830,342. Mine gallery supports. BECORIT GRUBENAUSBAU G.m.b.H. June 19, 1956 [June 20, 1955], No. 18971/56. Class 20(2) Mine gallery supporting frames 1 arranged perpendicularly to the working face are connected by parallel spring links 2 oblique to the frames when the ends of the frames are in line in order that they can be advanced one at a time. The frames may be advanced by a wedge moving transversely to the frames and engaging stops at the lower parts of the frames. The frames are shown connected by two sets of links for movement by a wedge moving in two opposite directions Figs. 7-9 (not shown).
