ABSTRACT:
Stow roller train for the storage and conveyance of cargo with rotatable cargo supporting rollers which can be coupled, by means of respectively one intermediate roller for each supporting roller which is movable into the driving or idling position, with a constantly moving traction means. Each intermediate roller is disposed in an axially fixed manner with respect to its axis of rotation and is radially adjustably movable with respect to this axis. A control force mechanism is effective on the intermediate rollers in the direction of the driving position. In a first embodiment, the intermediate rollers are continuously in contact with a drive belt serving as the traction means. Springs or lever and weight arrangements for the control force mechanism apply a predetermined force on the intermediate rollers toward the driving position. The intermediate rollers are radially movable away from the driving position in response to excess reaction forces at the cargo supporting rollers. The belt may be reversible to give different driving forces in opposite directions. In another embodiment, the intermediate rollers are mounted on pairs of toggle levers which include abutments removing the intermediate rollers from driving engagement with one or both of the drive belt and cargo supporting rollers.
