Abstract
Arrangements are for use with interconnected conveyor sections, such as push beams, commonly found in mining applications. In one embodiment a mechanism includes an elongated dog-bone shaped coupler having a first and second end for insertion between the conveyor sections. A first end of the coupler is secured to a first conveyor section, while a second end of the coupler is received in a recess formed in a second conveyor section. A pivotally mounted cam includes a recess for mating with the upwardly projecting, flared portion of the second end of the coupler. The cam pivots automatically upon being engaged by a free end of the coupler to allow it to pass and then pivots to capture it in place, thereby simply establishing a secure manner of connection. In another, the ends of the conveyor sections are specially adapted to form an articulating joint.
