Abstract
An anti-rattle hitch device is described. A rotating barrel pin is positioned proximate to the normal accessory port of receiving hitch housing. The pin cooperates with resilient bushings that are engineered to compress in overload situations, while urging the accessory drawbar flush against the upper, inner facing of the housing when the device is engaged under normal conditions. The resulting apparatus prevents unwanted rattling and play of the hitch and accessory without the need for loose or removable parts.
