US Classification:
1988442, 474253, 411339
Abstract:
A fastener for splicing ends of conveyor belts together is provided having a rivet that is pre-inserted thereto to provide speed and ease in installation. The rivet is held in an aperture of the upper plate by an interference fit at the lower end thereof. Preferably, the interference fit is achieved by knurling of the lower end portion of the rivet shaft to create raised interference portions or ridges integral therewith that are sized to be in an interference fit in the upper plate aperture. The remainder of the shaft can be sized to provide clearance between it and the aperture. An applicator machine tool is also provided for automatically securing a strip of the pre-inserted rivet fasteners to a belt end in a fast and efficient manner. The tool uses operating members to first drive pilot nails through the belt lower surface into registry with the rivets, and thereafter the rivets are driven coordinated with the pilot nails that are withdrawn back through the belt. The pilot nails stop at a predetermined position and the rivets continue to be driven for forming the upset heads at the bottom of the rivet.

Abstract:
A hinged fastener for splicing transverse ends of conveyor belts together with the belt fastener having teeth that are bent from one of the fastener plates for piercing and sinking into the belt to increase the holding power of the fastener. In the preferred form, the fastener is attached to the belt end with two rivets with the teeth being adjacent the rivets to provide a small, low cost, high performance fastener. The teeth are formed by bending them down from the outer edge of the plate and about a bend line parallel to the inner edge of the plate so that the teeth face the belt end to keep the teeth from being pulled through the belt material. The location of the teeth adjacent the rivets maximizes the depth of penetration of the teeth into the belt for improved fastener holding power and minimizes the likelihood that the teeth will be bent upward and lose holding power when the belt is highly tensioned.

Abstract:
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.

Abstract:
A belt fastener having an upper plate and a lower plate with holes which align with holes in a pair of belt ends, and bolts are inserted through the aligned holes of the plates and the belt ends, and nuts screwed onto the bolts, to connect the belt ends. A preassembled lower plate and bolt combination is provided in which bolts are retained in their respective lower plate apertures by washers disposed on the bolt shanks. The washers are disposed on the bolt shanks sufficiently close to the lower plate to maintain anti-rotational engagement of the bolts with the lower plate, and spaced sufficiently far from the lower plate to allow outward swinging of the bolts to an insertion position for insertion of the bolts through the belt holes in an outwardly swung position for subsequent drawing together of the bolt and belt ends. The washers are displaceable along their shanks into abutment with the lower plate and deformable under the pressure associated with clamping together of the plates about the belt ends, whereby the washers deform and fill in the spaces between the bolts and the lower plate. The washers are preferably formed with flexible resilient tabs about a central aperture, with the tabs being deflected by the bolt shanks when slid onto their shanks to prevent washer material from being scraped off the washer and into the threads of the bolt when the washer is initially applied to the bolt.
