ABSTRACT:
The apparatus has a flat, flexible concave/convex tape retractably coiled into a spool having a housing which is mounted on a suitable gimble. The gimble is fixedly mounted on the towing vehicle so that the spool axis is horizontal. A suitable eyelet is provided on the end of the tape so that the eyelet is substantially above the ball hitch when the tape is fully retracted. On the towed vehicle, a vertical rod is disposed aligned above the ball socket and the rod is adapted to receive the eyelet. The gimble allows the spool to rotate about a vertical axis and also allows the spool housing to pivot about another horizontal axis spaced above the spool's axis. A micro-switch is provided which responds to tape tension when tape is withdrawn from housing, and a potentiometer is provided which relays responses to horizontal rotation of the housing. A display, in the form of a meter, is provided in sight of the operator of the towing vehicle, which meter measures the potentiometer setting and a display in the form of an indicator light is provided which responds to the micro-switch to indicate when the tape is fully retracted or withdrawn, i.e., off when retracted, on when withdrawn.
