Title: Staple fastening tool

Abstract: An applicator apparatus for securing belt fasteners to belt ends by staples comprises a staple guide block means having resiliently biased pin means for exerting a clamping force to hold the belt end against shifting during the driving of the staples through the belt and the clinching of the ends of the staples against the belt fasteners. The preferred applicator is formed to accommodate various widths of belts by releasably securing a series of separate applicator units each having a staple guide block and secured to a base plate in predetermined and aligned portions thereon. An adjustable cam lever allows shifting of the staple guide block means to accommodate different thicknesses of belts. A gauge pin is eliminated by having shoulder surfaces on the staple guide block means hold the belt fasteners with their hinge pin receiving ends in alignment with one another.
