Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 328 words
An adjustable hitch ball mount for use in conjunction with a coupler connected to a trailer, said hitch ball mount comprising a support part, said support part including opposite side faces terminating in an end edge, means for attaching said support part to a towing vehicle with said support part side faces being generally vertically oriented and in general alignment with the direction of travel of the towing vehicle, said support part having a plurality of spaced parallel generally vertically aligned openings extending therethrough from one said side face to the other, a bracket including a hitch ball and a U-shaped channel part defined by spaced flanges, a first pair of aligned openings in said flanges, a second pair of aligned openings in said flanges, each second pair opening being elongated with opposite ends and located spacedly from a said first pair opening, said bracket fitted over said support part end edge and having each flange thereof overlying a side face of the support part, said first and second pairs of openings being aligned with a pair of said openings in the support part, a first bolt member extending through one of said support part pair of openings and said first pair of bracket openings, a second bolt member extending through the other of said support part pair of openings and said second pair of bracket openings, said bolt members fitting complementally within said support part pair of openings, said first bolt member constituting pivot means about which said bracket may shift relative to the support part, said second bolt member being shiftable laterally between the ends of said second pair of bracket openings to pivot said bracket about said first bolt member and to vary the angular relationship of said bracket relative to said support part whereby said hitch ball is shiftable between multiple positions, and means carried by said second bolt member and compressed against said bracket for securing said bracket in a selected angular position.
Claim 2
Dependent Claim 328 words
An adjustable hitch ball mount for use in conjunction with a coupler connected to a trailer, said hitch ball mount comprising a support part, said support part including opposite side faces terminating in an end edge, means for attaching said support part to a towing vehicle with said support part side faces being generally vertically oriented and in general alignment with the direction of travel of the towing vehicle, said support part having a plurality of spaced parallel generally vertically aligned openings extending therethrough from one said side face to the other, a bracket including a hitch ball and a U-shaped channel part defined by spaced flanges, a first pair of aligned openings in said flanges, a second pair of aligned openings in said flanges, each second pair opening being elongated with opposite ends and located spacedly from a said first pair opening, said bracket fitted over said support part end edge and having each flange thereof overlying a side face of the support part, said first and second pairs of openings being aligned with a pair of said openings in the support part, a first bolt member extending through one of said support part pair of openings and said first pair of bracket openings, a second bolt member extending through the other of said support part pair of openings and said second pair of bracket openings, said bolt members fitting complementally within said support part pair of openings, said first bolt member constituting pivot means about which said bracket may shift relative to the support part, said second bolt member being shiftable laterally between the ends of said second pair of bracket openings to pivot said bracket about said first bolt member and to vary the angular relationship of said bracket relative to said support part whereby said hitch ball is shiftable between multiple positions, and means carried by said second bolt member and compressed against said bracket for securing said bracket in a selected angular position.
Claim 3
Dependent Claim 72 words
The hitch ball mount of claim 1 wherein said second bolt member carried means includes a washer encircling said second bolt member and positioned against a said flange of the bracket, one of said washer and last mentioned flange having a serrated face, a nut means threaded onto said second bolt member for urging said washer compressively against said last mentioned flange with said washer and flange interlocking at said serrated face.
