Patent number: 6488144Abstract: 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surface into registry with the rivets, and thereafter the rivets are driven coordinated with the pilot nails that are withdrawn back through the belt.Type: GrantFiled: December 6, 2001Date of Patent: December 3, 2002Assignee: Flexible Steel Lacing CompanyInventors: John H. Winkelman, Joseph C. Vogrig, Gary E. Mitas

Patent number: 6053308Abstract: 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.Type: GrantFiled: September 23, 1997Date of Patent: April 25, 2000Assignee: Flexible Steel Lacing CompanyInventors: Joseph C. Vogrig, John H. Winkelman, Edward C. Musil

Patent number: 5852877Abstract: A belt skiving apparatus and method in which a free-standing blade-carrying carriage is employed which does not require a guiding base. The carriage has a pair of rollers defining a nip into which a belt end to be skived is passed. The rollers press together about the belt end to securely grip the belt. One of the rollers is toothed to provide a non-slip engagement with the surface of the belt and at least one of the rollers is driven, preferably manually, through a crank arm. Rotation of the rollers advances the carriage relative to the belt to advance the carriage across the width of the belt. As the carriage is advanced, the belt is passed through the rollers and through a cutting blade disposed adjacent the rollers. As the carriage is advanced along the width of the belt, the blade slices a thin strip of the upper portion of the belt adjacent its upper face from the remainder of the belt. The thin strip that is removed is the portion of the belt that was punctured by the teeth of the driving roller.Type: GrantFiled: July 23, 1996Date of Patent: December 29, 1998Assignee: Flexible Steel Lacing CompanyInventors: David A. Lotarski, Joseph C. Vogrig

As the carriage is advanced, the belt is passed through the rollers and through a cutting blade disposed adjacent the rollers, with the blade slicing a thin strip of the upper portion of the belt adjacent its upper face from the remainder of the belt. The rollers may be driven by a ratchet arm to move the carriage along the belt end. Preferably, two pairs of rollers are employed on the carriage, one forward and one rearward of the blade to cut the uncut portion remaining at the trailing side of the belt after the belt passes through the forward roller pair.Type: GrantFiled: June 6, 1995Date of Patent: June 30, 1998Assignee: Flexible Steel Lacing CompanyInventors: David A.

Patent number: 5524808Abstract: Illustrated and described is a nailing gun conversion for use in driving and setting rivets to attach belt fasteners to conveyor belts and the like. The conversion involves a special nose piece and drive rod for the gun for cooperation with the modified head of a multiple pronged rivet driver used for the simultaneous driving and setting of a cluster of nail-pointed self-setting rivets maintained in position for assembly with the belt fasteners and belt by a fixture of known construction.Type: GrantFiled: April 26, 1994Date of Patent: June 11, 1996Assignee: Flexible Steel Lacing CompanyInventor: Joseph C.
