Abstract
1,056,690. Endless conveyers. GULLICK Ltd. Nov. 3, 1965 [Nov. 26, 1964], No. 48046/64. Heading B8A. The combination of a mine roof support and a face conveyer comprises a rear support unit with a base 10, hydraulically extensible telescopic legs 11 with a roof-bar or canopy 12, a forward support unit with a single hydraulically extensible leg 13 mounted in a base 14 and a roof-bar 15 pivotally connected at 16 to the canopy 12 and to an endless conveyer 20. The rear unit 10, 11, 12 and the forward unit 13,14, 15 are connected by a base-plate 21 hinged to the base 10 at 22 and welded to the base 14, the conveyer 20 being accommodated between the rear unit 10, 11, 12 and the forward unit 13, 14, 15 and being slidably mounted on the baseplate 21. The cylinder 17 of a double-acting hydraulic ram is secured by lateral trunnions (not shown) in the base 10 and the piston-rod 18 of the ram is attached, by means of a clevis 19, to the conveyer 20. As shown, the apparatus is in the position occupied immediately prior to a cut being made on the coal face F. The conveyer 20 is provided with a floor-engaging ramp 23 extending longitudinally of the conveyer and interrupted at intervals by triangular recesses to accommodate the bases 14 of the forward support units. At its forward part the ramp 23 has guide means 28 which align with guide means 26 on the bases 14 to form a guide along the coal face F for a cutting machine (not shown). During the cutting operation the cutting machine also loads coal on to the conveyer 20. The cutting machine then ploughs back to the stable (not shown) and loads coal which has fallen on to the floor into the conveyer 20. Using the conveyer 20 as an anchorage the support 10 to 15 is advanced by retracting the piston-rod 18. The piston-rod 18 is then advanced to push the conveyer 20 forwardly during which advance the ramp 23 and auxiliary ramps 25 by the bases 14 scrape the floor and serve to guide material into the conveyer 20.
