A combination of a belt fastener having upper and lower plates joined by arcuate hinge loops and staples preassembled in apertures formed in the upper plates is provided with the staples cooperating with the plates to capture an end of a belt between the plates. The edges of the apertures provide the staples with vertically spaced areas of interference fit with the combination of the preassembled staples and fasteners being effective to reduce the time required to install these plate-type fasteners on bell ends while also holding the staples in an upright, pre-set position against forces that would otherwise cause the staple to slide against the aperture edges until a sufficient driving force is applied for driving the legs through belt material to attach the fastener on a belt end. Further, the preassembled staple and fastener herein can be designed such that upon applying the fastening driving force to the preassembled staples, the staples slide through and bear against the surrounding edges of the upper plate apertures against the interference fit and through the thickness of the belt end such that inner curved portions on the staple joining the staple legs to the head or bight section of the staple engages four inner, lower edges around the upper plate apertures in recessed pockets in which the apertures are formed to bend these edges into tangs and to embed the four tangs into the belt. |
