A scraper chain conveyor with an assembly composed of two centrally disposed chains interconnected at intervals with scraper elements and locking brackets. Each scraper element is tapered in cross-section and has a recess through which the chains extend and the underside of the central portion of the element overlying the recess has shaped compartments receiving horizontal links of the chains and depending lugs extending through these links. The lateral ends of the recess are bounded by apertured webs which mate with apertured end portions of the associated bracket which is disposed beneath the chains. The end portions of the bracket are offset in relation to the remainder of the bracket and have recessed parts which accommodate the heads of the connecting bolts extending through the apertures so as to prevent rotation of the bolts.
