  • Patent number: 5896981
    Abstract: The apparatus of the present invention includes a tube having locking apparatus at one end that is inserted into a hinge joint in a first direction. A lead wire is inserted into the tube in the opposite direction and locked in place within the tube. Then the tube is withdrawn from the joint with the lead wire still attached. The apparatus also includes a web shaped bib member having at least one opening therein for gripping by a human hand to assist in positioning the belt. The method of the invention has application to a method of securing the first end of a conveyor belt with respect to the second end of the conveyor belt wherein the first end and second end each include part of a hinged joint that includes a plurality of cylindrical section shaped members.

  • Patent number: 5881863
    Abstract: A belt lacing is provided for conveyor belts of the type used in installans with a trough zone, where the conveyor belt is supported on both sides curved towards the top. The conveyor belt ends are joined together with a hinge joint or lacing, which is exclusively located outside of the curved sections of the trough zone of the conveyor belt. The hinge joint or lacing contains coupling eyes which are fastened to the conveyor belt and at least one connecting pin, which passes through the intermeshing coupling eyes. The conveyor belt excels because of the minor wear in laterally flexing transition areas of the conveyor belt during passage through the trough zone. Moreover, it is simply constructed and can be manufactured in an uncomplicated way.

  • Patent number: 5234101
    Abstract: The invention refers to a conveyor belt connecting element provided with a loop with leg-like extensions, the loop being intended to accommodate a coupling rod, as well as with openings in the leg-like extensions for inserting staples that serve to attach such connecting elements to the end of a conveyor belt. The essence of the invention is that the particular leg of the conveyor belt connecting element against which the free end of the staple legs rest, is provided with sloping contact surfaces for the free ends of the staple legs, and that the respective slope runs from the openings, provided for the staples, towards the loop as well as in the direction of the conveyor belt.

  • Patent number: 5095590
    Abstract: 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.

  • Patent number: 4942645
    Abstract: A fastener and fastener assembly for coupling the ends of a conveyor belt to form a continuous belt where the preferred embodiment is a belt fastener having an upper and lower arm connected by a loop, and having a belt stop positioned to limit insertion of a conveyor belt end. The assembly utilizes a first and second set of fasteners mounted on opposite belt ends which intermesh to define a hinge passage for a hinge pin to couple the belt ends together. The reach-back of the belt ends into the belt fasteners is maximized as the belt stops are aligned with their belt loops and positioned to abut the belt end at a location where the exterior surface of a belt loop of the opposite belt fasteners is engaging or nearly engaging the belt end.

  • Patent number: 4937921
    Abstract: An anti-sifting arrangement for plate and wire-type belt fasteners with hinge loops. A block of flexible material, such as an open-cell reticulated foam, is disposed in the hinge loop area and spans adjacent belt fasteners. A hinge pin inserted into the meshed hinge loops compresses the foam block which also expands to fill the voids between the belt ends, hinge loops and hinge pin to prevent sifting of particulate matter through the splice. The foam block is retained in position by the belt stops or the end of the belt and may be readily inserted or removed from the belt fastener assembly.

  • Patent number: 4935996
    Abstract: A hinge and clasp connection especially adapted for use in jewelry items where it is desirable to separably connect two components and at the same time enable relative pivotal movement between the connected components. The combination hinge and clasp includes interdigitated hinge barrels with a pin engaged with the hinge barrels in one position and disengaged from at least one of the interdigitated hinge barrels when in another position to enable the barrels to be retained in pivotal, aligned condition or separated for separating components of a jewelry item.

  • Patent number: 4653156
    Abstract: A fastener for conveyor belting has a plurality of fastener elements form a strip adapted to join the ends of the of conveyor belting with the aid of a coupling rod. Each strips forms one half of the fastener and its parallel connecting elements have legs and eye lugs for the purpose of forming eyes to receive and encompass a coupling rod after the legs of the two halves have been secured to the two belt ends and after the two belt halves have been brought into alternate interlocking engagement. The elements are secured to the ends of the belting by using pin-like fastening means such as staples. A non-leaking connection and a grease lubrication of the coupling rod are provided by a caulking filler in the form of a molded body of a rubber elastic material with eye lug grooves and fin elements which are aligned with the respective eye lugs of the connecting strip as an extension thereof and the molded body encompasses the coupling rod at least in part.

  • Patent number: 4641398
    Abstract: A device for coupling the hinge-knuckles of two complementary series of belt-fasteners fixed respectively on each edge of a conveyor belt is constituted by a series of independent rod segments. The maximum length of each segment corresponds to the length of the hinge-knuckles of two opposite belt-fasteners. The rod segments have relatively displaced portions each corresponding to the width of one hinge-knuckle and are thus stationarily fixed in the longitudinal direction after positioning. The different segments are initially joined together by means of at least one temporary coupling member which is readily shearable at the time of initial use and troughing of the conveyor belt.

  • Patent number: 4344209
    Abstract: A clipper seam for use with a pintle or lacing unit to join adjacent ends of a papermakers belt or the like. The clipper seam comprises two seam webbings, each of which is woven as a one-piece unit to form a pocket for receiving one of the ends of the papermakers belt. As woven, the pocket is defined by first and second flaps, each of the flaps having an inner surface and an outer surface, the inner surfaces being in a spaced relationship to define the pocket, which is adapted to receive one of the ends of the papermakers belt. Each of the outer surfaces define a stepped, tapered construction. A tongue portion also forms part of the seam webbing. Recessed margins are provided on both the top and bottom surfaces of the tongue, near the distal end or selvage of the tongue. A plurality of clipper hooks adapted to receive one or more pintles are secured to the tongue within the recessed margin.
