Abstract
Abstract A towing apparatus having a wheel lift assembly, a bumper assembly, a boom assembly and a sheave assembly, all of which may be utilized independently. The wheel lift assembly includes a pair of wheel cradles for receiving the wheels of a disabled vehicle. The wheel lift assembly has a horizontal towing position but the assembly is selectively pivoted into a folded highway position. The bumper assembly has a pair of bumper members, each attached to a support arm that is fixed to a vertically movable upright member at a separate pivot. The bumper assembly may be used to bumper tow a disabled vehicle. The bumper members are selectively detachable for folding the bumper assembly in a highway position. The boom assembly includes a pair of boom arms that are caused to be moved vertically in conjunction with the upright member. Each boom arm is attached at a separate pivot and, like the wheel lift assembly and the bumper assembly, the boom assembly includes members which are selectively elongatable. The sheave assembly is fixed atop the upright member and includes a pulley for receipt of a winch cable. The present invention further includes a pair of hydraulically extendable stabilizer wheels for the elimination of light front ends normally associated with the towing of heavy loads.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
168 words
A vehicle towing apparatus for attachment to a towing vehicle comprising, an upright member having a first end coupled to a towing vehicle, power means for providing vertical movement to said upright member, a bumper assembly having a pair of bumper members and having a pair of bumper support arms in communication with said upright member for vertical movement therewith, each bumper member having a first end and a second end, each bumper support arm being connected to a first end of a bumper member and having a separate pivot connection for communication with said upright member, said bumper assembly having a means for selectively connecting said second ends of said bumper members and having a bumper towing means, a wheel lift having a lift arm pivotally attached to said upright member, said lift arm having a towing means for supporting the wheels of a vehicle to be towed, and means for selectively pivoting said lift arm from a road proximity position to a road clearing towing position.
Claim 2
Dependent Claim
168 words
A vehicle towing apparatus for attachment to a towing vehicle comprising, an upright member having a first end coupled to a towing vehicle, power means for providing vertical movement to said upright member, a bumper assembly having a pair of bumper members and having a pair of bumper support arms in communication with said upright member for vertical movement therewith, each bumper member having a first end and a second end, each bumper support arm being connected to a first end of a bumper member and having a separate pivot connection for communication with said upright member, said bumper assembly having a means for selectively connecting said second ends of said bumper members and having a bumper towing means, a wheel lift having a lift arm pivotally attached to said upright member, said lift arm having a towing means for supporting the wheels of a vehicle to be towed, and means for selectively pivoting said lift arm from a road proximity position to a road clearing towing position.
Claim 3
Dependent Claim
75 words
The towing apparatus of claim 1 wherein said means for selectively pivoting said lift arm includes an elongated mounting member and a sleeve slidably fit about said mounting member, said mounting member being fixed to said upright member for vertical movement therewith, said sleeve having a crossbar diagonally extending to said lift arm and a means for locking said sleeve in position relative to a random horizontal plane, thereby causing said lift arm to pivot.
Claim 4
Dependent Claim
23 words
The towing apparatus of claim 2 wherein said sleeve has a locking pin means for positionally locking said sleeve to said mounting member.
Claim 5
Dependent Claim
37 words

Claim 7
Dependent Claim
41 words
The towing apparatus of claim 1 further comprising a boom assembly having a pair of boom arms, each boom arm being in communication with said upright member at a separate pivot near said free end for rotation about a vertical axis.
Claim 8
Dependent Claim
16 words
The towing apparatus of claim 1 further comprising a sheave assembly mounted atop said upright member.
Claim 9
Dependent Claim
23 words
The towing assembly of claim 1 further comprising a pair of pneumatic stabilizer tires and power means for vertically extending said stabilizer tires.
Claim 10
Dependent Claim
164 words
A vehicle towing apparatus to be fitted onto a towing vehicle comprising, an upright member having a first end coupled to a towing vehicle, power means for vertical reciprocation of said upright member, a wheel lift assembly having a lift arm pivotally attached to said upright member at a first pivot point, said lift arm having a first towing means for securing a vehicle to be towed and having a substantially road clearing towing position and a road proximity position, and a lift arm pivot means having an elongated mounting member affixed parallel said upright member for vertical movement therewith and having a sleeve slidably fit about said mounting member, said wheel lift assembly having a crossbar extending from said lift arm for attachment to said sleeve, said sleeve having a means for releasably locking said sleeve in place relative to a horizontal plane, thereby causing said crossbar to pivot said lift arm at said first pivot point upon movement of said upright member.
Claim 11
Dependent Claim
164 words
A vehicle towing apparatus to be fitted onto a towing vehicle comprising, an upright member having a first end coupled to a towing vehicle, power means for vertical reciprocation of said upright member, a wheel lift assembly having a lift arm pivotally attached to said upright member at a first pivot point, said lift arm having a first towing means for securing a vehicle to be towed and having a substantially road clearing towing position and a road proximity position, and a lift arm pivot means having an elongated mounting member affixed parallel said upright member for vertical movement therewith and having a sleeve slidably fit about said mounting member, said wheel lift assembly having a crossbar extending from said lift arm for attachment to said sleeve, said sleeve having a means for releasably locking said sleeve in place relative to a horizontal plane, thereby causing said crossbar to pivot said lift arm at said first pivot point upon movement of said upright member.
Claim 12
Dependent Claim
34 words
