  • Patent number: 10099524
    Abstract: Method and apparatus for an adjustable trailer hitch which allows each of three differently sized user selected balls to be adjusted laterally and longitudinally so that the tongue of the trailer can be more easily attached to the towing vehicle. The trailer hitch has a body portion mounted on a slide-tube for insertion in a receiver-tube wherein the body portion has an interior space which allows the draw bar to move laterally from side to side inside the space along with a plurality of apertures so that the draw bar can be laterally adjusted using the apertures and a locking pin. When the draw bar is moved all the way to the left or right the user selected ball is automatically aligned with the receiver tube due to the effective sizing of the draw bar which is assured by the right and left stops of the body portion contacting the right and left outer edges of the draw bar.
