Abstract

A wire belt fastener is formed from a piece of wire to have a wire body having a pair of arms joined by a U-shaped hinge pin section. The ends of the wire are flattened to form wide areas having grooves to receive the head and the bent ends of a staple. The fasteners are aligned in a juxtaposed array by a connector wire or rod extending normal to the arms and spanning across a series of belt fasteners to space them evenly to receive interdigitated hinge loops of another array of belt fasteners. A belt stop comprising a projecting piece of wire is secured to an inner surface of one arm of the wire belt fastener to be abutted by the cut belt end to limits its insertion into the gap between the arms of the wire belt fastener. To reduce the lateral width of the belt fasteners and to place more metal in the splice, the wire cross-section at the hinge loop is substantially oblong with flat faces of adjacent, intermeshed fasteners being side by side. The wire body is oblong in shape except for the flattened ends without having to cut away metal from the wire body and scraping the severed metal. When bending the wire into a U-shape, the interior hemispherical surface becomes wider than the outer hemispherical surface at the hinge loop.
