ABSTRACT:
A manually operated four bar linkage on a conveying device permits manual removal of preforms or other workpieces when they have not been ejected from the device at the desired unloading station. The linkage device has a cam track located adjacent to the return path of an endless type conveyor. The cam track is manually brought into conjunction with the couplings or collets which have accidentally retained a preform to force the coupling mechanism to move to a release position thus enabling manual removal of the preform. Preferably a bar or similar knock-out device is located downstream of the point where the cam track engages the coupling to ensure that all such preforms or other workpieces are removed.
