Abstract
Abstract Detachably secured to the towing sling of a tow truck is a substantially horizontal frame including on opposite lateral sides a pair of adjustable wheel cradles arranged to support either the front or the back wheels of a vehicle to be towed. The wheel cradles can be installed under the wheels to be supported while the wheels are on the ground and when the towing sling elevates the frame the superposed wheels and adjacent end of the vehicle are raised for towing.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
161 words
A wheel supporting attachment for a tow truck sling comprising: a. a substantially horizontal frame includng an after transverse cross bar, a forward transverse cross bar, and a pair of longitudinal rails extending between a forward end and an after end, the after ends of said longitudinal rails being detachably secured to said after cross bar with intermediate portions of said longitudinal rails underlying said forward cross bar; b. a pair of fore and aft wheel cradles supported on said forward cross bar and said after cross bar, said wheel cradles being located on the opposite lateral sides of said frame and transversely spaced apart a distance such as to support a pair of wheels of a motor vehicle to be towed; and, c. means for attaching said frame to said sling with either the front wheels or the rear wheels of the vehicle to be towed lodged in said wheel cradles for elevation by said sling to vehicle towing position.
Claim 2
Dependent Claim
161 words
A wheel supporting attachment for a tow truck sling comprising: a. a substantially horizontal frame includng an after transverse cross bar, a forward transverse cross bar, and a pair of longitudinal rails extending between a forward end and an after end, the after ends of said longitudinal rails being detachably secured to said after cross bar with intermediate portions of said longitudinal rails underlying said forward cross bar; b. a pair of fore and aft wheel cradles supported on said forward cross bar and said after cross bar, said wheel cradles being located on the opposite lateral sides of said frame and transversely spaced apart a distance such as to support a pair of wheels of a motor vehicle to be towed; and, c. means for attaching said frame to said sling with either the front wheels or the rear wheels of the vehicle to be towed lodged in said wheel cradles for elevation by said sling to vehicle towing position.
Claim 3
Dependent Claim
74 words
A wheel supporting attachment as in claim 1 in which the ends of said after cross bar project laterally beyond the sides of the vehicle to be towed, said attaching means includes a tranverse beam detachably mounted on said sling, the ends of said transverse beam being coextensive with said after cross bar, and a pair of chains connecting the ends of said tranverse beam with the respective ends of said after cross bar.
Claim 4
Dependent Claim
27 words
A wheel supporting attachment as in claim 2 further including mounting means on the forward ends of said longitudinal rails for connecting said rails to said sling.
Claim 5
Dependent Claim
64 words
A wheel supporting attachment as in claim 1 in which each of said cradles includes a forward framework having a rearwardly and downwardly inclined plate and an after framework having a forwardly and downwardly inclined plate, a superposed wheel of the towed vehicle being supported on said forward and said after plates at approximately 5 o'clock and 7 o'clock when viewed in side elevation.
Claim 6
Dependent Claim
45 words
A wheel supporting attachment as in claim 4 in which said forward framework and said after framework each includes a transverse sleeve capable of slidably receiving said forward cross bar and said after cross bar, respectively, for laterally adjusting the distance between said wheel cradles.
Claim 7
Dependent Claim
40 words
A wheel supporting attachment as in claim 5 in which each of said cradles includes fore and aft telescoping means connecting said forward framework and said after framework and said after framework for longitudinally adjusting the distance between said plates.
Claim 8
Dependent Claim
66 words
A wheel supporting attachment as in claim 6 in which said telescoping means includes a channel provided with a plurality of spaced apertures and a slide bar translatably disposed in said channel, said slide bar including a plurality of openings spaced for registry with said apertures in said channel, and means insertable through registering apertures and openings for securing said frameworks in selected transversely spaced relation.
Claim 9
Dependent Claim
50 words
A wheel supporting attachment as in claim 4 in which said forward framework is separated from said after framework by a laterally inwardly opening wheel well to enable said wheel cradles to be installed in wheel supporting position by transverse inward movement toward a wheel in engagement with the ground.
