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: 5244088Abstract: Disclosed is a device for supporting a plurality of rivets in a desired orientation and spacing for insertion of the rivets as a group into the plurality of apertures of a belt fastener. The rivet holder comprises two portions which are releasably interconnected such that the two portions are separable upon application of manual force thereto to release the rivets from the rivet holder as a group upon application of manual force. In one embodiment, the rivet holder comprises two portions which are pivotally interconnected in such a manner that the two portions are not separable until sufficiently pivoted with respect to one another. This prevents the two portions from separating prior to the time of intended use, as may otherwise occur during transport or the like in which there may be forces acting on the rivets tending to force the two rivet holder portions apart which would result in the premature release of the rivets.Type: GrantFiled: April 16, 1992Date of Patent: September 14, 1993Assignee: Flexible Steel Lacing CompanyInventor: Edward C.

Patent number: 5095590Abstract: Each belt connector or each clip is substantially so U-shaped as to be engaged with both sides of the corresponding edge of a conveyor belt (T) in order there to be secured by means of a U-shaped fixing staple or cramp of metal wire, whose arms are pressed through apertures in the bowed parts of each clip and through the strip between them. In the bowed part of each clip, to receive the staple ends, each aperture disposed opposite a tine of such a staple is connected, by way of a groove or channel or the like contrived in the outside surface of this same zone, to another aperture through which the corresponding tine can be led. The same can therefore be returned to inside the clip in order there to be pressed again into the conveyor belt or to engage between the same and the corresponding bowed part of the clip, something which occurs automatically when the staple ends are bent around and pressed against an anvil on which the clips are supported while the staples are driven in and secured in situ.Type: GrantFiled: June 25, 1991Date of Patent: March 17, 1992Assignee: Goro S.A.Inventor: Jean-Francois Schick

Patent number: 5079807Abstract: This disclosure shows a novel shaped pintle wire for papermachine clothing. The intended use of the pintle wire is to close a pin seam by joining the loops formed by the machine-direction yarns at each end of an open-ended papermachine fabric. The present pintle has a non-circular cross section with a major dimension and a minor dimension. The major dimension stretches the loops and reduces seam gap. The minor dimension is approximately equal to the thickness of the fabric under load. Both serve to reduce the marking of the paper sheet by the seam region.Type: GrantFiled: June 22, 1989Date of Patent: January 14, 1992Assignee: Albany International Corp.Inventor: Paul F. Hood

Patent number: 4996750Abstract: A wire belt fastener is formed from a piece of wire to have a wire body having a pair of arms joined by a U-shaped hinge pin section. The ends of the wire are flattened to form wide areas having grooves to receive the head and the bent ends of a staple. The fasteners are aligned in a juxtaposed array by a connector wire or rod extending normal to the arms and spanning across a series of belt fasteners to space them evenly to receive interdigitated hinge loops of another array of belt fasteners. A belt stop comprising a projecting piece of wire is secured to an inner surface of one arm of the wire belt fastener to be abutted by the cut belt end to limits its insertion into the gap between the arms of the wire belt fastener. To reduce the lateral width of the belt fasteners and to place more metal in the splice, the wire cross-section at the hinge loop is substantially oblong with flat faces of adjacent, intermeshed fasteners being side by side.Type: GrantFiled: June 26, 1989Date of Patent: March 5, 1991Assignee: Flexible Steel Lacing CompanyInventor: Edward C.
