Abstract

1,100,140. Advancing milte-roof supports. GEWERKiSCHAFT EISENHUTTE WESTFALIA. 20, April, 1965 [21, April, 1964], No. 16525/65. Heading E1E. An advancing mine roof support assembly has two support frames of extendible props 10, 10 and 11, 11, resiliently connected together so that the props 10, 10 and also 11, 11 keep substantially parallel, the frames being connected through a hydraulic or pneumatic shifting arrangement comprising two double-acting rams with connected cylinders 17 linked to one frame and connected piston rods 18 linked to the other frame. The bars 15 are pivotably connected to the props at their ends by horizontal bolts 16 and the rams are parallel and one above the other. To do the linking U-shaped shackles 21 are connected to the cylinders by lugs 24 thereon and on a rail 20 secured to the piston rods 18 at their closed ends and to the bars 15 at their free ends by bolts 26 and spacing members 27.
