摘要：The live roller conveyor includes multiple power transmission devices eachmounted for movement between a retracted non-driving position and a position ofdriving relation between a friction drive wheel therein and at least one of the rollers. Eachof the power transmission devices includes an assembly wherein the drive wheel and thedriving sprocket therefor are rotationally mounted, and the main drive is a flexible drivechain, 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 deviceassemblies holds the chain in driving engagement with the associated sprocket in allmoved positions of the assembly, but has a separable connection with part of theassociated assembly wherein the driving sprocket is supported in order to effect releaseof the sprocket from the chain.
