  • Tightening mechanism for trailer drawbar hinge assembly and method of using same
    Patent number: 9108478
    Abstract: A tightening mechanism for a hinge assembly includes a first housing having a pair of outwardly extending spaced apart ears having aligned first bores extending through them. A second housing has a length which allows it to fit between the ears and has a pair of abutting second bores which are tapered inwardly toward one another. Tapered cylindrical bushings are configured to fit within the second bores. The tapered bushings have aligned third bores which are co-axial with one another and with the second bores. A coupling mechanism extends through the third bores and holds the second housing rotatably in the first housing. A clamping mechanism urges the bushings toward one another and inwardly into the second bores against the pin.
