ABSTRACT:
A belt fastener assembly for fastening belt ends together comprises: first and second retention plates receiving and retaining substantially abutting belt ends between the plates, and defining a plurality of bolt holes. A plurality of threaded bolts each extend through a bolt hole of each of the first and second plates and also extend through portions of the belt positioned between the plates, to retain the first and second plates and the belt ends together, with nuts carried on the bolts. Washers are also carried on the bolts, each having an aperture and having, in an original condition prior to use, a frustoconical inner area surrounding the aperture to enlarge the aperture to a size of at least the outer diameter of the bolt threads. This facilitates placement of the washers on the bolts. Then, the washers may be flattened to decrease the size of the apertures, to retain the bolts in position extending through a retention plate prior to full assembly.
