ABSTRACT:
A drivable load-carrying roller assembly comprises a conveyor roller, roller-driving structure at an end of the roller and a clutch disposed at that end for coupling the roller to the driving structure and operable by linear displacement of structure formed on or displaceable with a guard member shielding the said driving structure. The guard member advantageously comprises a plate displaceable in a direction at right angles to the roller and provided with cam structure engageable with one part of the clutch for shifting that part, in the axial direction of the roller, in relation to another clutch part, whereby the coupling of the roller to the driving structure by the clutch is controlled. The said one clutch part may be spring-loaded towards its clutch-engaging position and movable to its clutch-disengaging position by the cam structure or movable towards both its engaging position and its disengaging position by the cam structure.
