Abstract
A vehicle adapted to be conveyed along a track has an upper platform for supporting an article thereon. The platform is adapted to be inclined selectively to one side or the other of the track allowing the article being carried to slide off the vehicle into a chute but is maintained in the horizontal position by a locking device. As the vehicle approaches an unloading chute, the locking device is automatically unlocked and the platform is pivoted to one of its two inclined positions.
