1,105,602. Endless conveyers. SHAW, TREW & SMITH Ltd., and D. G. SHAW. 18 June, 1965 [19 March, 1964], No. 11585/64. Heading B8A. An endless conveyer has a conveying surface 1 provided by a pair of series of plates 2, 2 each of which is pivoted at 5 to a roller chain 4. The plates 2, 2 of each series have a lap joint 3, to provide continuity of the conveying surface in the operative run. As shown in full lines the plates 2, 2 are mutually inclined in a trough-like manner, so as to be able to convey material such as coal, the gap between the plates 2, 2 being closed by a spine 11. The roller chain 4 runs on a platform 15 which may be raised by hydraulic means (not shown). When the platform 15 is raised the two series of plates 2, 2 are mutually inclined in an outwardly downward direction so that side discharge of the conveyed material can take place as shown in dotted lines. Discharge may be obtained from one side only by having only one series of pivoted plates 2, the other series being fixed. Alternatively or additionally tracks 14 may be vertically operable either together or independently. All the plates 2 may be pivoted about a common central longitudinal axis, e.g. in a hinge-like manner, in which case a spine 11 is not required. In a further arrangement a single series of pivoted plates 2 may co-operate in the operative run with and travel relative to a fixed plate or like surface mutually inclined to the single series of plates 2 in the conveying condition (not shown).
