ABSTRACT:
A reel assembly is especially adapted for winding an electrical service cord in either recreational or industrial vehicles. The reel has flanges rotatively mounted to an arbor, and only one end of the arbor is fastened to a rigid supporting member. The reel assembly therefore has one flange clear of any obstruction so that the electrical cord can be wound readily over the end of the reel to adjust tension, and the mounting provides easy assembly and disassembly. In a preferred embodiment, the reel is held on the arbor by a single fastener associated with a slip-ring assembly. A notched ratchet disk has protrusions adjacent its notches to cause a pawl to jump across the notches except at slow speeds. For safety, a grounding circuit is completed through a special conductive, retractive spring to eliminate open circuits sometimes encountered with usual sets of electrical contacts.
