Wire Strands Reinforce Belts Patents (Class 24/31W)
  • Patent number: 5341545
    Abstract: A fastening arrangement is provided to interconnect the opposite ends of a elt or the like, and includes a plurality of individual belt fasteners arranged side-by-side across the width of the belt ends. The belt fasteners include mounting portions which are impressed into the opposing faces of the belt end, such that the overall width of the belt tends to thereby expand and distort. A longitudinally inelastic tensioning element is positioned along a major portion of at least one of the belt ends, and is attached thereto, so as to generally maintain the overall width of the associated belt end and resist distortion thereof.

  • Patent number: 4489828
    Abstract: A steel connector for joining the steel cable ends of a conveyor belt is provided. The connector comprises a pair of tubular sleeves--one of which is slipped onto each cable end. Each sleeve has a bore having an inner section of reduced diameter relative to the outer section. The cable end is expanded radially, by driving a cone into its end, and then the expanded end is wedged tightly into the inner section of the sleeve to fix them together. Bridging members are threaded into the outer sections of the two sleeves to hold them together in lineal alignment. The bridging members are operative to permit the sleeves to flex relative to each other.

  • Patent number: 4437849
    Abstract: A belt is described for use as an emergency replacement for a regular drive or timing belt. The belt comprises an elongated flexible member which has an integral ratchet type connecting means provided on its opposite ends. The flexible member is cut to form a loop of the desired size and the opposite ends are then connected using the ratchet connecting means without requiring any special additional connecting members or tools. The belt is useful, for example, in automobiles as an emergency replacement for the conventional fan belt or other engine belts where a belt fails in use and where the replacement belt permits the motorist to drive a sufficient distance to reach a garage for a regular belt replacement.

  • Patent number: 4279606
    Abstract: A pulley belt for emergency replacement of a ruptured auto fan or water pump pulley belt in which the pulley belt ends are firmly interconnected to form a closed loop thereof by using wedge blocks to engage an external length of cable molded integral during fabrication of the pulley belt. This manner of connecting the pulley belt ends is not only readily achieved without tools, but is improved strengthwise during power transmission service of the pulley belt by the pulling force exerted on the cable.
