Abstract
A conveying system is provided for moving a pallet along straight and curved paths. The conveying system includes a track on which the pallet is mounted for movement by means of a motor driven roller pivotally mounted on the pallet which engages a stationary shaft mounted on the track. Depending on the position of the drive roller in relation to the shaft, the pallet is driven forward, rearward, or remains stationary. The drive roller is resiliently urged into contact with the shaft and is pivotally mounted on the pallet so as to be movable between a forward drive position, a rearward drive position, and a stationary position. A resilient bias urges the drive roller to the forward drive position. A cam mechanism is provided to move the drive roller to the stationary position when desired.
