ABSTRACT:
A cable hanger for use in a cable-guided fishing operation is disclosed. The disclosed invention provides a cable hanger in which a specially-shaped hanger body is connected to a handle having a cable groove running through it. The cable groove allows for the centerline of a cable to run through the centerline of the handle, thereby allowing for a straight-line pull to be exerted on the cable through the cable hanger. The specially-shaped hanger body is operatively connected to a specially-shaped body cover by a plurality of links. In this way, the hanger body and cover form a “clamshell” arrangement in which the cover can rotate from an open position to a closed position around the cable. When in the closed position, the cover and body are bolted together along the side of the cover and body opposite the links. The hanger body and cover are designed such that the cable rests closer to the links rather than in the center of the hanger body such that the moment arm between the bolts and the cable is increased, thereby increasing the amount of clamping force that can be provided by the bolts.
