ABSTRACT:
A jack is mounted on a trailer tongue by a swivel connection to pivot between a vertically disposed active position and a horizontally disposed stowed position. The swivel connection includes a spacer sandwiched between a bracket on the tongue of the trailer and a bracket on the housing of the jack and rotatably received in a hole in the tongue bracket. The spacer serves to hold the two brackets out of contact with one another. A bolt extends through the housing bracket and the spacer with a non-rotatable fit and causes the housing bracket and the spacer to turn in unison relative to the tongue bracket. A nut and washer on the inner end of the bolt clamp the brackets together while allowing the housing bracket to pivot relative to the tongue bracket. The tongue bracket may either be clamped to the tongue by bolts or may be bolted to still another bracket which is welded to the tongue.
