Abstract
A gripper conveyor assembly includes a plurality of grippers. A conveyor chain moves the grippers along a track from a pick up station to a receiving station. The conveyor chain has identical links. Any one link can be removed from the chain while all of the other links remain interconnected and enclosed by the track. Each of the links includes a body section with rollers which engage the track to guide movement of the body section along the track. Plug and socket type universal joints interconnect the body sections of the links. An opening having a length corresponding to the length of the body section of a link is provided in the track. When a link is rotated, through approximately 90.degree. at the opening, the plug and socket joints can be disconnected and the rotated link removed from the conveyor chain.
