Abstract
Abstract A vehicle jack and dolly for quickly and easily raising the vehicle includes a support which is slipped around the bottom of the tire from the side of the vehicle, pivot bars and axles that are parallel to, spaced from and rotatable around the pivot bar. Short bars extending from the axles may be forced downward to rotate the axles and lift the vehicle to the point where a hook drops in place to lock it. The axles have small wheels so that two dollies may be used on two opposite wheels to move the vehicle.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
154 words
A jacking dolly comprised of firs and second identical frames coupled by a first tubular member on said first frame telescoping into a second tubular member on said second frame, each of said identical frames comprising: a pivot bar, the ends of said pivot bar connected between structural plates, one of said plated being attached to one of said tubular members; an axle parallel to said pivot bar and spaced therefrom by a journaled member coupled between said axle and said pivot bar, said axle coupled for rotation about said pivot bar, said axle supporting at least two wheels; lifting means associated with said journaled member for rotating said axle and said wheels for raising said jacking dolly; locking means associated with said journaled member for locking said rotated axle and said wheels; and at least one bar forming a vehicle tire support attached between said structural plates and parallel to said pivot bar.
Claim 2
Dependent Claim
154 words
A jacking dolly comprised of firs and second identical frames coupled by a first tubular member on said first frame telescoping into a second tubular member on said second frame, each of said identical frames comprising: a pivot bar, the ends of said pivot bar connected between structural plates, one of said plated being attached to one of said tubular members; an axle parallel to said pivot bar and spaced therefrom by a journaled member coupled between said axle and said pivot bar, said axle coupled for rotation about said pivot bar, said axle supporting at least two wheels; lifting means associated with said journaled member for rotating said axle and said wheels for raising said jacking dolly; locking means associated with said journaled member for locking said rotated axle and said wheels; and at least one bar forming a vehicle tire support attached between said structural plates and parallel to said pivot bar.
Claim 3
Dependent Claim
54 words
The jacking dolly claimed in claim 1 wherein said lifting means is a bar having one end attached to said journaled member at said axle and slanted outward in a direction away from said jacking dolly, said bar adapted to be extended by an extension pipe for rotating said axle about said pivot bar.
Claim 4
Dependent Claim
39 words
The jacking dolly claimed in claim 1 where said locking means includes a hook coupled to said vehicle tire support bar, said hook engaging a bar coupled to and spaced from said axle when said dolly has been raised.
Claim 5
Dependent Claim
29 words
The jacking dolly claimed in claim 1 wherein said structural plates are triangular and said tire support includes two parallel bars having their end attached between said structural plates.
Claim 6
Dependent Claim
50 words
The jacking dolly claimed in claim 1 further including means for preventing separation of said two identical frames from separating including a chain having one end connected to one of said tubular members, said chain having links engagable with a pin extending from the other one of said tubular members.
Claim 7
Dependent Claim
21 words
The jack dolly claim in claim 1 wherein said axle supports two wheels, each having a diameter of approximately six inches.
Claim 8
Dependent Claim
