Abstract
The live roller conveyor includes multiple power transmission devices each mounted for movement between a retracted non-driving position and a position of driving relation between a friction drive wheel therein and at least one of the rollers. Each of the power transmission devices includes an assembly wherein the drive wheel and the driving sprocket therefor are rotationally mounted, and the main drive is a flexible drive chain, the driving run of which extends through the successive power transmission devices. A chain retaining member forming a part of each of the power transmission device assemblies holds the chain in driving engagement with the associated sprocket in all moved positions of the assembly, but has a separable connection with part of the associated assembly wherein the driving sprocket is supported in order to effect release of the sprocket from the chain.
