Abstract
Abstract A hydraulic vehicle lift and tow bar mounted at the rear of a tow truck which has a beam supporting two frames that are placed under a pair of wheels of the vehicle to be towed. A hydraulic cylinder raises the beam to lift the towed vehicle. The frames are pivotedly mounted to allow turning during towing and to permit them to be folded back against the beam during storage. The beam telescopes to reduce the distance it protrudes behind the truck when not in use.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
212 words
A vehicle lift and tow bar comprising in combination: (a) a telescoping beam having an outer casing and an inner arm reciprocating therein; (b) first mounting means for pivotedly attaching for up and down motion of said telescoping beam one end of said outer casing under and to the frame of a truck with said inner arm directed towards the rear of said truck beyond the end thereof; (c) a hydraulic cylinder attached to said outer casing and in use to said frame for effecting said up and down motion; (d) second mounting means pivotedly connected to the outer end of said inner arm for rotation in a generally horizontal plane; and (e) a wheel carrier pivotedly mounted by said second mounting means, said wheel carrier having two spaced apart frames adapted to engage from the underside a pair of wheels of a vehicle and lift the same, said pair of frames being pivotedly mounted to said second mounting means for rotation about a first axis generally horizontal and perpendicular to the longitudinal axis of said inner arm when in the use position, said pivotal mounting permitting rotation of said pair of frames from a position extending beyond the outer end of said inner arm to a position alongside said outer end.
Claim 2
Dependent Claim
212 words
A vehicle lift and tow bar comprising in combination: (a) a telescoping beam having an outer casing and an inner arm reciprocating therein; (b) first mounting means for pivotedly attaching for up and down motion of said telescoping beam one end of said outer casing under and to the frame of a truck with said inner arm directed towards the rear of said truck beyond the end thereof; (c) a hydraulic cylinder attached to said outer casing and in use to said frame for effecting said up and down motion; (d) second mounting means pivotedly connected to the outer end of said inner arm for rotation in a generally horizontal plane; and (e) a wheel carrier pivotedly mounted by said second mounting means, said wheel carrier having two spaced apart frames adapted to engage from the underside a pair of wheels of a vehicle and lift the same, said pair of frames being pivotedly mounted to said second mounting means for rotation about a first axis generally horizontal and perpendicular to the longitudinal axis of said inner arm when in the use position, said pivotal mounting permitting rotation of said pair of frames from a position extending beyond the outer end of said inner arm to a position alongside said outer end.
Claim 3
Dependent Claim
47 words
The lift and tow bar of claim 1 wherein means are provided for locking said pair of frames in a locked extended position generally horizontal to the ground, said locking means, when released permitting rotation of said pair of frames to a retracted position approximately 180° therefrom.
Claim 4
Dependent Claim
63 words
The lift and tow bar of claim 1 wherein said second mounting means extends beyond the outer end of the inner arm by a sufficient amount to permit at least 90° rotation of said wheel carrier such that said wheel carrier can be rotated from the use position to a folded position with said first axis and said longitudinal axis being generally parallel.
Claim 5
Dependent Claim
38 words
The lift and tow bar of claim 1 including means for locking said telescoping beam to said frame when said telescoping beam is in its elevated and tow position whereby hydraulic perssure need not be maintained during towing.
