Abstract
Abstract A towing apparatus for a rail bound vehicle is described. The towing apparatus includes both a lifting device for lifting the wheel load off of a defective wheel, tire or axle and a mobile support which supports the load, normally supported by the defective wheel, during a towing operation. The lifting device occupies a minimum of space and is supported by the road surface rather than by the rail. The mobile support may be conveniently and positively engaged with a defective wheel hub under conditions wherein a minimum of maneuvering space is available.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
232 words
A towing apparatus for a vehicle having wheels guided between a pair of parallel rails comprising: mobile support means for supporting hub means of said vehicle during a towing operation; said mobile support means comprising narrow elongate bridge means extending parallel to a towing direction during said towing operation, seat mounting means attached to said bridge means for positively abutting said hub means, and first roller means rotatably mounted at a forward end of said bridge means and second roller means rotatably mounted at a rearward end of said bridge means for enabling said mobile support means to move along a surface with said vehicle during said towing operation, said seat mounting means interposed between said first and second roller means, stationary lifting means for temporarily lifting said vehicle to allow said mobile support means to be positioned under said vehicle hub means, said stationary lift means being removable after positioning said mobile support means and prior to said towing operation; said stationary lifting means comprising horizontal cross bar means, vertically disposed angular support means attached to each end of said cross bar for supporting said cross bar adjacent one of said wheels and above one rail of said pair of rails in a non-contact relationship with said one rail, jacking means disposed on said cross bar for lifting said vehicle, and attachment means for attaching said jacking means to said vehicle.
