Claim 5

For use with a ball carrying hitch arm secured to the rear of a towing vehicle centrally thereof and a trailer having a socket carrying arm to arrange a hookup coupling between said ball and said socket; a trailer hitch visual alignment device comprising (a) a pair of magnetic bases one of which is attachable to the body of the towing vehicle and the other of which is attachable to the socket carrying arm of the trailer, (b) alignment wands carried by each of said magnetic bases and being adjustably secured to its respective base through a minimum arc of 90°, (c) an elastic gromet on each alignment wand and being slidable along the length thereof, (d) a pair of alignment flags, one for each wand and having a foot extending off its base and being adapted to be retained between said elastic gromet and said wands, (e) and a pair of plumb lines each having a plumb bob at one end, said plumb lines being adapted to be passed through the elastic gromet between the wand and gromet until the plumb bobs are positioned one above the towing ball and the other above the towing socket when the plumb lines pass between the elastic gromet and alignment wand opposite said alignment flags.

Claim 6

For use with a ball carrying hitch arm secured to the rear of a towing vehicle centrally thereof and a trailer having a socket carrying arm to arrange a hookup coupling between said ball and said socket; a trailer hitch visual alignment device comprising (a) a pair of magnetic bases one of which is attachable to the body of the towing vehicle and the other of which is attachable to the socket carrying arm of the trailer, (b) alignment wands carried by each of said magnetic bases and being adjustably secured to its respective base through a minimum arc of 90°, (c) an elastic gromet on each alignment wand and being slidable along the length thereof, (d) a pair of alignment flags, one for each wand and having a foot extending off its base and being adapted to be retained between said elastic gromet and said wands, (e) and a pair of plumb lines each having a plumb bob at one end, said plumb lines being adapted to be passed through the elastic gromet between the wand and gromet until the plumb bobs are positioned one above the towing ball and the other above the towing socket when the plumb lines pass between the elastic gromet and alignment wand opposite said alignment flags.
