ABSTRACT:
A conveyor belt assembly is provided with a pair of spaced parallel endless conveyor belts which are spanned by a plurality of equally spaced, parallel rods. Each of the conveyor belts are joined together at their opposite belt ends by a pair of belt fasteners secured to the belts and having hinge loops intermeshed and connected by a hinge pin. The preferred pin has a constant diameter and retainers at opposite ends of the hinge pin to abut the belt fasteners to prevent lateral sliding of the hinge pin. The preferred retainers are enlarged heads on opposite ends of the hinge pin. Other retainers are tru-arc rings positioned in grooves formed in the hinge pin. The preferred belt fasteners are all identical in shape and have first and second notches in their respective side edges to receive the enlarged heads. When the belt fastener is forwardly facing, the enlarged head will be nested in a first notch; and where the belt fastener is rearwardly facing the enlarged head will be in the second notch. In another embodiment, the belt fasteners are made substantially narrower than the belt width to leave room for retainers at the outer edges of the belt fasteners without interference with side edge guides for the conveyor belt.
