Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
161 words
An appliance for use in sling-towing a vehicle formed to provide a pair of laterally-spaced, downwardly-facing frame members adjacent an end of the vehicle with relatively fragile depending parts in proximity with said frame members, by means of a sling comprising a lifter bar, an anchor bar connected to said lifter bar by flexible strap means and hook means connected to said anchor bar by flexible strand means, said hook means being engaged with the vehicle chassis, said appliance comprising cross beam means spanning said frame members, two upstanding posts longitudinally spaced from each other on the upper surface of said beam means and engageable respectively with the downwardlyfacing surfaces of said frame members to support said vehicle end and space said beam means below said relatively fragile parts, said beam means being interposed between said strand means and said relatively fragile parts, and cooperating means mounting at least one of said posts for independent adjustment longitudinally on said beam means.
Claim 2
Dependent Claim
161 words
An appliance for use in sling-towing a vehicle formed to provide a pair of laterally-spaced, downwardly-facing frame members adjacent an end of the vehicle with relatively fragile depending parts in proximity with said frame members, by means of a sling comprising a lifter bar, an anchor bar connected to said lifter bar by flexible strap means and hook means connected to said anchor bar by flexible strand means, said hook means being engaged with the vehicle chassis, said appliance comprising cross beam means spanning said frame members, two upstanding posts longitudinally spaced from each other on the upper surface of said beam means and engageable respectively with the downwardlyfacing surfaces of said frame members to support said vehicle end and space said beam means below said relatively fragile parts, said beam means being interposed between said strand means and said relatively fragile parts, and cooperating means mounting at least one of said posts for independent adjustment longitudinally on said beam means.
Claim 3
Dependent Claim
34 words
The appliance of claim 1 in which said beam means provides longitudinal trackway means along its upper surface and said posts are guided by said trackway means for independent movement along said trackway means.
Claim 4
Dependent Claim
25 words
The appliance of claim 1 including longitudinally-spaced, transversely-extending guide means on the lower surface of said beam means for cooperative reception of said strand means.
Claim 5
Dependent Claim
14 words
The appliance of claim 2 in which each post carries an upwardly-facing rubberoid pad.
Claim 6
Dependent Claim
143 words
A towing device for a vehicle having laterally spaced apart downwardly facing frame members adjacent an end of the vehicle, said device comprising, in combination, an anchor bar having a center portion and opposite end portions, means for lifting said anchor bar, a pair of hooks for engaging laterally spaced apart portions of the underside of such a vehicle, strand means for connecting said hooks respectively to said opposite enD portions, and cross beam means interposed between said strand means and the vehicle to rest on said strand means, said cross beam means providing two upstanding posts longitudinally spaced from each other for engaging respectively such frame members and two longitudinally spaced guideways engaging respectively said strand means, the distance between said posts being adjustable along the cross beam means, and cooperating means on the cross beam means and posts providing said adjustment.
Claim 7
Dependent Claim
143 words
A towing device for a vehicle having laterally spaced apart downwardly facing frame members adjacent an end of the vehicle, said device comprising, in combination, an anchor bar having a center portion and opposite end portions, means for lifting said anchor bar, a pair of hooks for engaging laterally spaced apart portions of the underside of such a vehicle, strand means for connecting said hooks respectively to said opposite enD portions, and cross beam means interposed between said strand means and the vehicle to rest on said strand means, said cross beam means providing two upstanding posts longitudinally spaced from each other for engaging respectively such frame members and two longitudinally spaced guideways engaging respectively said strand means, the distance between said posts being adjustable along the cross beam means, and cooperating means on the cross beam means and posts providing said adjustment.
