Abstract
An elevator for a conveyor system and adapted to move articles between two different vertical levels. The elevator comprises a pair of endless chains mounted to travel in parallel offset vertical paths. The opposite corners of a plurality of platforms or carriers are connected to the respective chains and as the chains move in their paths of travel, the platforms move in a generally rectangular path consisting of an upward vertical run, an upper horizontal run, a downward vertical run, and a lower horizontal run. Horizontal conveyors located at different vertical levels intersect the vertical runs of the platforms, and the platforms are provided with recesses so that the platforms can move vertically around the conveyors. Articles to be conveyed are delivered to the elevator by one of said conveyors, and are individually lifted from the conveyor by a platform moving in the upward vertical run. The platform carrying the articles is then transferred horizontally and the article is subsequently deposited on the second conveyor as the platform moves in its downward vertical run.
