Abstract: A multi-section conveyor is assembled from at least one power driven section and a plurality of non-powered sections that derive operating power from the powered section through a coupler linking the sections in tandem. The conveyor sections each have opposite end rollers with a central roller core carrying a diametric cross-pin. The coupler between each pair of sections consists of a pair of shafts linked to transmit the rotation of one shaft to the other, and each shaft is receivable within one of the roller cores. The shaft end so receivable is slotted to engage the cross-pin and thus becomes locked into rotation with the roller. One of the shafts may extend relatively further than the other for initial engagement of the coupler with one roller at a time, and the shaft diameter of one or both shafts may be reduced adjacent to the axial position of the slot where the cross-pin will be located after the coupler is fully engaged with both rollers to provide dynamic locking of the coupler to the joined conveyor sections during conveyor operation.

Abstract: In a multi-section conveyor, a conveyor section provides a belt tension adjusting mechanism employing extension arms on an expanding tensioner. The extension arms carry the end belt roller and apply increased tension to the belt as the arms extend. The opposed end rollers of adjacent sections are joined to coaxial end gears, and an intermediate idler gear interconnects the end gears when the sections are joined. When sections are assembled, the extension arms mate into the neighboring section and are contoured to permit angular variation in the mating. A latching mechanism on one section locks the end roller of the next section in engagement slots and boxes the gears for safety.
