Abstract
A conveyor trough particularly for scraper chain conveyors comprises a plurality of transversely extending interconnected plates with adjacent plates having abutting edges with alternately arranged projecting tongues and recesses which define a hinge connection between the longitudinally adjacent plates. The plates are advantageously substantially flat and include tongue formations formed by recesses made either on the top or the bottom of the plate for selectively defining underlying or overlying tongues.
