ABSTRACT:
A load carrying unit for use along a predetermined conveying track including an endless moving conveyor chain. The load carrying unit is provided with a depending vertically movable conveyor chain engagement pin which is selectively movable between a conveyor chain engaged position coupling the load carrying unit to the conveyor chain so that the load carrying unit moves with the conveyor chain, and a conveyor chain disengaged position uncoupling the load carrying unit from the conveyor chain. The device for disengaging the movable pin from the conveyor chain includes an elongated pivotally attached horizontal bar extending transversely along the front end of the load carrying unit and spaced forwardly therefrom and engagable with a rear end of a downstream load carrying unit which pivots the elongated bar inwardly toward the load carrying unit. The elongated bar engages a pin actuator which lifts the pin out of engagement with the chain conveyor and also engages a pin stabilizer which comprises a compression spring actuated on one end in response to movement of the elongated bar and a second end of the spring contacts a horizontal movable rod which in turns contacts the chain engagement pin in the disengaged position. Through friction contact the rod holds the chain engagement pin in a disengaged position being so long as the elongated bar is engaged with the rear end of the downstream load carrying unit.
