  • Patent number: 4392676
    Abstract: A hose handling device has a fitting adapted to be secured to one end of a hose. The fitting has a peripheral groove in its exterior surface in which a ring is mounted for relative rotational movement with respect to the fitting. An eye adapted to be engaged by a hook is fixedly secured to said ring. Advantageously, the eye is formed by opposed legs which conform to the outer diameter of the ring and are secured thereto by welding or the like. Preferably, the inner diameter of the ring has a relatively flat central portion each side of which is connected to a slightly beveled portion which, in turn, may be connected to a more sharply beveled portion connected to an exterior face of the ring. To facilitate swivelling the inner diameter of the ring may have a peripheral groove communicating with a grease fitting mounted on the exterior of the ring. The fitting may be connected to one end of a hose and have its other end threaded for connection to a threaded fitting.
