Abstract
A conveyor system comprising a conveyor track, a conveyor movable along said track, a free track and a plurality of carriers movable along the free track. The conveyor has longitudinally spaced pusher and holdback dogs mounted thereon. Each carrier comprises spaced trolleys, and tie bar means interconnecting the trolleys. A trailing trolley has a pusher movably mounted thereon for movement into and out of the path of the pusher and holdback dogs. A bumper is mounted on the carrier at the front end thereof and is adapted to engage a preceding carrier or an obstacle. Means interconnect the bumper and the retractable pusher such that upon engagement of the bumper with the preceding carrier or obstacle the pusher is retracted out of the path of the pusher dog. The arrangement is such that the trolleys can pivot horizontally and vertically with respect to the means interconnecting the trolleys so that the system will function with horizontally and vertically curved tracks.
