Abstract
Abstract A sway control adaptor for mounting one end of a sway control assembly to a towing vehicle adjacent the trailer hitch is disclosed. The adaptor includes a upper elongate member having one part which overlies a portion of the trailer hitch and a second part extending transversely from the first part. A lower elongate member underlies that portion of the trailer hitch, and is bolted to the upper elongate member to mount the members to the hitch. A sway control hitch ball is mounted to the free end of the second part of the upper elongate member for attachment of the leading end of the sway control device to the towing vehicle on one side of the hitch.

Claim 1
Independent Claim
143 words
Apparatus for mounting one end of a sway control assembly to a towing vehicle adjacent the trailer hitch, said apparatus comprising: an upper elongate member having a first section adapted to overlie a portion of the trailer hitch and a second section extending transversely from the first section, said second section including a vertically disposed aperture for mounting a sway control hitch ball thereto; a lower elongate member adapted to underlie said portion of the trailer hitch, said lower elongate member including flange means adapted to at least partially circumscribe said portion of the trailer hitch to restrict movement of the upper and lower members with respect to said hitch; and means for interconnecting the first section of the upper elongate member with the lower elongate member to compress said portion of the trailer hitch therebetween to mount the members to said hitch.
Claim 2
Dependent Claim
143 words
Apparatus for mounting one end of a sway control assembly to a towing vehicle adjacent the trailer hitch, said apparatus comprising: an upper elongate member having a first section adapted to overlie a portion of the trailer hitch and a second section extending transversely from the first section, said second section including a vertically disposed aperture for mounting a sway control hitch ball thereto; a lower elongate member adapted to underlie said portion of the trailer hitch, said lower elongate member including flange means adapted to at least partially circumscribe said portion of the trailer hitch to restrict movement of the upper and lower members with respect to said hitch; and means for interconnecting the first section of the upper elongate member with the lower elongate member to compress said portion of the trailer hitch therebetween to mount the members to said hitch.
Claim 3
Dependent Claim
50 words
Apparatus as recited in claim 1 wherein the first section of the upper elongate member and the second elongate member include a plurality of corresponding apertures, and wherein the connecting means comprises a plurality of bolts adapted to pass through the corresponding apertures to interconnect the upper and lower members.
Claim 4
Dependent Claim
143 words
Apparatus for mounting one end of a sway control assembly to a towing vehicle adjacent the trailer hitch, said apparatus comprising: an upper elongate member having a first section adapted to overlie a portion of the trailer hitch and a second section extending transversely from the first section, said second section including a vertically disposed aperture for mounting a sway control hitch ball thereto; a plurality of set screws engageable with the first elongate member and adapted to intersect said portion of the trailer hitch to prevent sliding of said upper member with respect to the hitch; a lower elongate member adapted to underlie said portion of the trailer hitch; and means for interconnecting the first section of the upper elongate member with the lower elongate member to compress said portion of the trailer hitch therebetween to mount the members to said hitch.
Claim 5
Dependent Claim
143 words
