A system for splicing a conveyor belt with belt fasteners is disclosed. A base assembly aligns the belt, belt fasteners and rivet holes thereof with swage structures for securing the rivets. A guide assembly has a rigid guide block with cylindrical pilot holes, and a guide membrane of resilient material. Guide pins are receivable by guide bores for aligning the base and guide assemblies with the pilot holes, rivet holes, and swage structures in registry. The guide membrane including openings aligned with the pilot holes. The openings have a pair of slits defining flaps deflectable to permit the rivet to pass therethrough, and a central hole or cut-out. The flaps and the cut-out assist in centering the rivet with the belt fastener rivet holes. The system uses a single-rivet driver, a multi-rivet driver, a pneumatic driver, or an electric hammer.

Apparatus and system for installing rivets in belt fasteners

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.

Belt fastener assembly

An anvil for use in riveting one element to another element such as belting and a clasp for the belting. The anvil defines at least one aperture, and preferably a plurality thereof, for receiving detachable, rivet-carrying nails, whereby a rivet carried on the nail has an end that faces the anvil. The anvil defines an outer face surrounding the aperture for engaging and shaping the rivet end. The outer face is free of adjacent, upstanding walls beyond the normal diameter of the rivet and outside of and facing the aperture. Accordingly, the rivet end may spread freely outwardly from the aperture as the anvil shapes the rivet end, contrary to the prior art.

Riveting anvil

An apparatus for orienting a fastener in a clasping arrangement with a workpiece, the fastener presenting a first leg and a second leg joined by a bight intermediate the first leg and the second leg, comprises a deflector for engaging the first leg and the second leg. The deflector comprises a generally planar surface and a single cavity intersecting the surface in a substantially elliptical opening having a major axis and a minor axis. The cavity has at least a first interior wall and a second interior wall. The first wall slopes from the opening in a first direction toward a depth limit; the second wall slopes from the opening in a second direction toward the depth limit. The depth limit is substantially coincident with one of the first axis and the second axis. The deflector structure and the fastener interact when meeting in response to a driving force by the first leg being deflected along the first wall in the first direction and by the second leg being deflected along the second wall in the second direction.

A belt fastener assembly attachment apparatus attaches belt fastener assemblies to the end of a belt with rivets and with a non-manually powered rivet assembly driving tool. A guide template having a plurality of guide apertures is alignable with the anvil die apertures of an anvil die plate. Each guide aperture receives and aligns the rivet assembly dispensing barrel of the non-manually powered rivet assembly drive tool to the anvil die apertures of an anvil die plate and rivet receiving apertures of the belt fastener. Guide pins carried by the guide template and received within guide apertures of the anvil die plate maintain the guide template apertures in registration with the anvil die apertures of the anvil die plate and the rivet receiving apertures of the belt fastener. A rivet assembly supply strip presents each rivet assembly one at a time in accurate registration with the rivet assembly dispensing barrel of the non-manually powered rivet assembly drive tool to assure accurate driving of each rivet assembly.

A system for affixing a device to a workpiece comprises a dynamic fastener applicator for imparting motion to a fastener with respect to the workpiece by urging the fastener along a path so that the fastener piercingly encounters the workpiece and fixedly engages the device with the workpiece. The system includes a static fastener applicator for effecting clasping engagement of the workpiece and the device by the fastener by a deflecting structure located in the path traveled by the driven fastener which orients the fastener to a clasping configuration for establishing the desired clasping engagement. The system further comprises a positioning apparatus for precisely establishing desired relative positions of the workpiece, the dynamic fastener applicator, the static fastener applicator, and the device for the desired clasping engagement. The positioning apparatus includes a plurality of pins and a plurality of pin-positioning structures which cooperate to laterally situate the dynamic fastener applicator, the device, and the deflecting structure for appropriately effecting the desired clasping engagement.
