Abstract
1,082,543. Advancing mine-roof supports. GEWERKSCHAFT EISENHUTTE WESTFALIA. Aug. 31, 1964 [Sept. 2, 1963], No. 35514/64. Heading E1E. In an advancing mine roof support assembly comprising two support units (Fig. 1) each having a floor bar 1, props 2 and roof girders 3, one unit has fixed thereto a piston 5 of a shifting device 5, 6, the cylinder 6 thereof engaging a guide rail 7 fixed to the other unit or to an auxiliary unit associated with both units, for guidance and being clampable to any position therealong. One of the units may have one prop and to it may be fixed the piston or the cylinder. There are various ways of clamping. The auxiliary unit may comprise a shifting device 13 for a conveyor 10 (Fig. 5) with an independent setting prop at 2<SP>1</SP> and two guide rails 14, each one engaged by a respective component, and one assembly may be connected to an adjacent one by a gobbing wall 12. The auxiliary unit may comprise a single guide rail engaged by a component of both devices - one with each support unit.
