ABSTRACT:
A trailer tongue twister apparatus having an elongated channel-like bedplate including a threaded drive screw disposed longitudinally in the bedplate and supported thereform at the opposite ends of the screw by a pair of journal supports, the method of construction including a hex head nut at one end of the drive screw for rotating the screw through a threaded hole formed within a cylindrically shaped block trunnion affixed to a load-bearing sled that travels along a pair of flanges when the drive screw is rotated, the sled carrying a cylindrical receiver ring fashioned for receiving a support leg of a travel trailer tongue jack, while rotation of the drive screw applied an alignment force to the tongue jack resulting in fine adjustments to the trailer coupler, which simplifies the alignment process and improves the coupler efficiency by permitting alignment between the trailer coupler and a staionary tow vehicle ball hitch in either a horizontal or angular pattern.
