Abstract: A lateral trailer tongue jack has a base plate for resting on a ground surface beneath a trailer tongue. The base includes a lateral channel iron track having a framework disposed over the track. A vertically oriented tubular socket has a wheel mounted at a lower end thereof which rides in the track. A lead screw disposed laterally across the framework is engaged with a threaded floating carriage within the socket. The socket accepts the lower end of a vertical tongue jack of the trailer. A crank attached to the lead screw is used to move the socket laterally along the track to align the trailer tongue hitch socket with the hitch ball of a towing vehicle.
