Abstract: 18,879. Hamilton, W. E. Sept. 8. Conveyers; elevators; loading; shoots.-Relates to improvements in machines for loading and storing coal and other loose material and comprises a gathering-conveyer which feeds a delivery conveyer by means of a shoot, each conveyer being capable of independent rotation about a vertical axis on the truck on which they are both carried. Fig. 1 is a side elevation of the whole machine ; Fig. 8 shows a cross-section of the gathering- conveyer ; Fig. 10 is a plan of the lower end of the gathering-conveyer, and Fig. 13 shows means whereby the gathering-conveyer can always deliver to the other conveyer. The conveyers are mounted on a truck 1 which can be moved along a line of rails by chain gearing driven from a motor. The truck carries a turntable 2 which is rotated by the motor and to which one end of a belt conveyer 13 is attached by a horizontal pivot. This conveyer is further supported by an upright 17 fixed to the turntable, and its inclination can be adjusted by a rope 30 through pulley tackle 18 and an equalizing- lever 26. This lever has two unequal arms in order that the strain on the supporting-cables 28 may be equal.. The end drum of the conveyer is adjustable lengthways of the conveyer frame. The gathering-conveyer 7, which is of the pushplate or scraper type, is attached by an horizontal pivot to a collar 6 loose on an upright 4 carried by the turntable. Inside the upright is a vertical shaft 11 which drives the conveyer chain. The scrapers 118 are attached to the links of the chain and are formed with tail pieces 119 which run in angle-iron guides 110 and maintain the scrapers in operative position. The floor and sides of the conveyer are lined with plates 133, fitted on both sides of the conveyer the chain of which can be driven in either direction. The tension of the conveyer chain is adjusted by a screw device at the upper end of the conveyer. The lower end 91 of the conveyer is pivoted to the main portion so as to adapt itself to the surface of the material. The axis on which this part pivots intersects the chain run so that the adjustment of the chain is not interfered with. The part 91 is cut away as at 143 so that the scrapers may dig into the material. The conveyer is moved from side to side about the upright 4 as centre by two chains 99 which are actuated by a motor 9 through worm gearing 96, and pass around pulleys at the lower end of the conveyer to posts anchored in the ground at each side. The material is conveyed to a circular space above the upright 4, the floor of which is formed by a loose circular plate 138 which is provided with a shoot 141 extending into a shoot 142 hinged at 142a to the delivery conveyer 13. By this means the gathering-conveyer can always deliver into the delivery conveyer no matter at what angle they may be positioned. In another construction of the conveyer chain the base-piece of each scraper forms a part of the chain and is connected to the next base-piece by chain links. It is stated that this construction enables the scrapers to set themselves radially in passing around the pulley at the lower end of the conveyer.
