ABSTRACT:
In a coupling apparatus for a circulating tow conveyor in which the carriages are held on a track with a portion running parallel to circulating tow chain and in which a coupling finger on the tow chain cooperates with coupling means on the conveyor, the coupling finger of the tow chain is pivotally mounted in a housing and is normally held in its vertical position by means of a locking lever which prevents the finger from pivoting out of contact with the cooperating coupling on the carriage but does not prevent pivotal movement of the finger in the opposite direction so that carriages pushed faster than the tow chain moves can be moved past one or more fingers on the tow chain. A releasing lever is provided to release the locking lever and, therefore, the carriage when the release lever is operated.
