Abstract

1,079,202. Mine roof support frames. A. G. WILD & CO. Ltd. Nov. 8, 1965 [Oct. 2, 1964], No. 40164/64. Heading E1E. A mine roof support frame for inclined seams is provided on one side with inclined and wedge-shaped runners 30, 40 respectively and on the other side with supports 36, 46 carrying rollers 32. The runners may be selectively attached to the frame by bolts engaging one of a series of rows of holes therein or the runners and rollers may be provided with adjustments to accommodate different horizontal or vertical alignments, the adjustment consisting of a double-acting hydraulic jack or a mechanical screw or wedge adjustment. The prop is connected to both the roof and floor bars by angled, interchangable or detachable pedestals.
