Abstract: 352,930. Scoop apparatus for transporting loose material. BROWN, S. WALTON-, Seghill Hall, Northumberland. Feb. 14, 1930, No. 5068. [Class 78 (iv).] Scoop apparatus for transporting material such as coal from the working face in mines or elsewhere is provided with troughing on the ground or on supports and either continuous or only on curves or at other selected places, the troughing guiding the scoops, bridging floor faults and facilitating loading into tubs, conveyers, &c. The scoop may have an open top and bottom and a pivoted door or flap at one or both ends and may be in sections. It may be of flexible construction to negotiate curves and may be fitted with antifriction devices. It may have a closed top to trap dust. Overhead guidance may also be provided for the scoop. A main and tail rope drum hauler may be used or a single hauling engine may be used both for scoop and tub haulage. Troughing.-The troughing sections may have bottom plates l, Figs. 3 and 4, with lateral channel irons m, the sections being connected by pins p on plates o at one end engaging holes r at the other end, securing cotters s being provided. The channel iron sides may be replaced by T or I members, wooden strips or other forms. The bottom plates may be arched, dished or of other form. The troughing may be tubular or of other form and may be made of pressed or cast steel. Various fastening devices for the sections may be used, such as slotted wings and bolts, hooks-andeyes, bolts and sockets or slip-on collars such as 3, Fig. 20, engaging turned back lips on the sections. The sections may be hinged either longitudinally or transversely. Various forms of hinge connections may be used such as a double hinge l, Fig. 36, or a hook connection l<1>, Fig. 43. The sections may be secured in position as by spikes fitted under the sections, or by cables passing through eyelets on the sections, or by chains 35, Fig. 60, engaging props 32, the troughing a in this case being one sided and hinged at a<1>. Lateral or overhead guide rollers may be fitted to the troughing or elsewhere for the haulage ropes and the sections may be fitted with extension sides at curves or other places. For use on double curves the troughing may be of I-section so as to be reversible or a reversible trough side may be used at the junction of the curves. Scoops.-A rectangular scoop comprises sides 52, Figs. 75 and 76, bridging pieces 53, a swing door or flap 55 on a hinge pin 54, and haulage rope connections such as 57. The scoop may have two hinged sides 62, Fig. 79, connected by a spreader 65. The scoops may have skids or wheels, ploughshaped or toothed ends and guiding flanges or the like engaging guides on the troughing, and may have rollers or other anti-friction devices. Holding down devices such as lateral ramps may be used. The scoops may have flaps at both ends or a flap readily fixable at either end as by a spring grip 85, Fig. 110, engaging a bolt 86. The scoop may have a closed bottom with downwardly opening doors. The scoop may be flexible as by using chains 92, Fig. 115, with hinged flaps 94 or by forming the scoop sides with pin and slot connections 105, Fig. 129, or making it of sections 108, Fig. 135, connected together as by linkage 110. Low constructions of scoop have narrow sides and the flap hinged either at the top or bottom. Methods of working.-Coal from the face c, Fig. 1, is put in the troughing a, lateral ramps being provided if required, and the coal is removed by the scoop d which is hauled by main and tail ropes f up inclined troughing a<1> to a bridge fitted with slopes 135 down which the coal is discharged into tubs k. The scoop has lateral cheeks d<1> adapted to run on carriers 134 on the bridge. The scoops may be used in tandem. The troughing may be suspended from the roof, or may be used only at curves or other selected places and may have flared ends, be single-sided and otherwise adapted for the conditions. The troughing and scoops may be arranged in various ways according to the conditions of working. For example, the troughing a<1>, Fig. 166, may lead to an endless belt or other conveyer 148, the scoop d<6> discharging on to the conveyer which discharges into tubs k. A single engine may be used to haul scoops and tubs by fitting the haulage ropes with terminal chains having readily disconnectable couplings, one link 184, Fig. 180, having a narrow hook-gap 185 through which a narrowed part 191 of the end link can be threaded to engage the parts.
