Abstract
Abstract A towing apparatus of the wheel lift variety is provided with wheel support members that move horizontally or vertically relative to a fixed-position support beam. The support members are mounted to the beam by pivotable, tapered collars and include a depending retainer that has both an extended height and depth to contact a substantial portion of the wheel circumference. The apparatus also provides means for rotating the support beam both above the below the horizontal. All of these features facilitate use of the towing apparatus.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
97 words
An apparatus for use in lifting and towing a vehicle, comprising: a support beam positionable below said vehicle; two wheel support members, each having an elongated arm and a wheel retainer; and means for mounting said wheel support members to opposing end portions of said support beam such that said arms in a generally horizontal orientation and for generally horizontally rotating said wheel support members from a laterally remote position spaced outwardly from the sides of the vehicle to a vehicle lifting position immediately adjacent to the outer sides of a pair of wheels on said vehicle.
Claim 2
Independent Claim
97 words
An apparatus for use in lifting and towing a vehicle, comprising: a support beam positionable below said vehicle; two wheel support members, each having an elongated arm and a wheel retainer; and means for mounting said wheel support members to opposing end portions of said support beam such that said arms in a generally horizontal orientation and for generally horizontally rotating said wheel support members from a laterally remote position spaced outwardly from the sides of the vehicle to a vehicle lifting position immediately adjacent to the outer sides of a pair of wheels on said vehicle.
Claim 3
Dependent Claim
18 words
The apparatus of claim 1 wherein said mounting means also permits vertical movement of said wheel support members.
Claim 4
Dependent Claim
31 words
The apparatus of claim 1 wherein said elongated arm of each said wheel support member includes an offset portion to provide clearance around the outer sides of said pair of wheels.
Claim 5
Dependent Claim
37 words
The apparatus of claim 1 wherein the arm of each said wheel support member is disposed above said support beam to thereby locate said arms in said vehicle lifting position spaced from the surface supporting said vehicle.
Claim 6
Dependent Claim
23 words
The apparatus of claim 4 wherein said wheel retainers comprise elongated curved plates that depend from said arms of said wheel support members.
Claim 7
Dependent Claim
18 words
The apparatus of claim 1 wherein each said wheel support member may be rotated independently of the other.
Claim 8
Dependent Claim
53 words
The apparatus of claim 1 wherein said mounting means includes two elongated collars pivotally connected to the opposing end portions of the support beam, each collar tapering from the forward end to the rear end and wherein said arms of said wheel support members are slidably engageable and vertically movable within said collars.
Claim 9
Independent Claim
117 words
An apparatus for use in lifting and towing a vehicle, comprising: a support beam; two wheel support members, each having an elongated arm and a wheel retainer; means for mounting said wheel support members to opposing end portions of said support beam such that said arms are in a generally horizontal orientation and for rotating said wheel support members generally horizontally from a laterally remote position spaced outwardly from the sides of the vehicle to a vehicle lifting position immediately adjacent to the outer sides of a pair of wheels on said vehicle; and means for permitting vertical movement of said wheel support members to facilitate location of said wheel support members in said vehicle lifting position.
Claim 10
Independent Claim
117 words
An apparatus for use in lifting and towing a vehicle, comprising: a support beam; two wheel support members, each having an elongated arm and a wheel retainer; means for mounting said wheel support members to opposing end portions of said support beam such that said arms are in a generally horizontal orientation and for rotating said wheel support members generally horizontally from a laterally remote position spaced outwardly from the sides of the vehicle to a vehicle lifting position immediately adjacent to the outer sides of a pair of wheels on said vehicle; and means for permitting vertical movement of said wheel support members to facilitate location of said wheel support members in said vehicle lifting position.
Claim 11
Independent Claim
76 words
An apparatus for use in lifting and towing a vehicle, comprising: a support beam; two wheel support members; and two generally horizontally disposed collars each connected to an opposing end portion of said beam, said collars having passages increasing in vertical dimension from a forward end to an enlarged rear end; said wheel support members being mounted within said collar passages in generally horizontal orientation and configured to slide and move vertically within said collar passages.
Claim 12
Independent Claim
76 words
An apparatus for use in lifting and towing a vehicle, comprising: a support beam; two wheel support members; and two generally horizontally disposed collars each connected to an opposing end portion of said beam, said collars having passages increasing in vertical dimension from a forward end to an enlarged rear end; said wheel support members being mounted within said collar passages in generally horizontal orientation and configured to slide and move vertically within said collar passages.
Claim 13
Dependent Claim
56 words
The apparatus of claim 9 wherein each of said wheel support members includes an elongated arm having a wheel retainer mounted at one end and the other end adapted for receipt within one of the collar passages, whereby said arms slidably engage said collars to adjust the position of said wheel retainers relative to said beam.
Claim 14
Dependent Claim
30 words
The apparatus of claim 10 further including means for locking said wheel support members within said collars to thereby maintain the position of the wheel retainers relative to said beam.
Claim 15
Dependent Claim
48 words
The apparatus of claim 11 wherein said locking means includes a pin associated with each said collar and a plurality of apertures in the arms of each wheel support member, said apertures adapted to receive said pins to thereby prevent longitudinal movement of the arms within said collars.
Claim 16
Dependent Claim
32 words
The apparatus of claim 12 wherein said pin is affixed to said collar and protrudes upwardly into said collar passage, and said apertures are located in the bottom walls of said arms.
Claim 17
Independent Claim
125 words
An apparatus for use in lifting and towing a vehicle, comprising: a support beam positionable below the vehicle and having end portions which extend outside an opposed pair of wheels on said vehicle; two wheel support members, each including an arm and a wheel retainer; two collars, each pivotally connected to one of the end portions of said beam and adapted to receive one of the arms of said wheel support members to thereby mount said wheel support members to said beam and permit rotation of said wheel support members; each of said collars including a passage increasing in vertical dimension from front to back to permit vertical movement of said wheel support members; and means for locking said wheel support members within said collars.
Claim 18
Independent Claim
125 words
An apparatus for use in lifting and towing a vehicle, comprising: a support beam positionable below the vehicle and having end portions which extend outside an opposed pair of wheels on said vehicle; two wheel support members, each including an arm and a wheel retainer; two collars, each pivotally connected to one of the end portions of said beam and adapted to receive one of the arms of said wheel support members to thereby mount said wheel support members to said beam and permit rotation of said wheel support members; each of said collars including a passage increasing in vertical dimension from front to back to permit vertical movement of said wheel support members; and means for locking said wheel support members within said collars.
