  • Patent number: 4798569
    Abstract: An emergency belt assembly is provided for temporary replacement of broken fan belts and the like. The assembly comprises a tubular belt made of an elastomeric material, and a connector having a shank with a plurality of barbs on each end portion thereof. The maximum outer transverse dimensions of the barbs on each end portion of the connector decrease from the axially outermost barb to the axially innermost barb, thereby permitting the connector to be easily inserted manually into the tubular ends of the belt. In an alternate embodiment, the connector articulates at a point intermediate its end portions to permit the connector to easily accommodate small radii turns. In yet another embodiment of the present invention, the connector has a plurality of barbs on one end thereof for frictionally engaging the inner surface of a tubular end of a line or belt, and has on its opposite end portion an attachment member, such as an eye, for attaching to a support object, such as a pole, wall, or the like.
