Abstract
Abstract The dolly has a longitudinal main frame member which defines the front-to-back axis of the dolly. Axles are secured at right angles to the main frame member and carry rotatable wheels on the ends thereof. Each of the axles also rotatably carries a tire support pad which is latchable in a raised position. With the pads in a lowered position, the dolly is slid in a transverse direction under a wheel of the vehicle to be supported thereby. The tire support pads are then raised and locked to support that tire of the vehicle.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
126 words
A dolly, said dolly comprising: a frame, first and second axle shafts transversely secured to said frame adjacent the ends thereof, wheels mounted upon said shafts so that said wheels are rotatably mounted with respect to said frame so that said frame can be moved across a surface supported by said wheels; vehicle-supporting means comprising a pair of tire-engaging members, each pivotally mounted to one end thereof upon respective one of said shafts, said tire engaging members being movable from a lower, nonsupporting position to a raised, supporting position, said vehicle-supporting means being of such size as to be able to support a single vehicle tire; lock means interengaging between said vehicle-supporting means and said frame to maintain said vehicle-supporting means in the raised, vehicle-supporting position.
Claim 2
Dependent Claim
126 words
A dolly, said dolly comprising: a frame, first and second axle shafts transversely secured to said frame adjacent the ends thereof, wheels mounted upon said shafts so that said wheels are rotatably mounted with respect to said frame so that said frame can be moved across a surface supported by said wheels; vehicle-supporting means comprising a pair of tire-engaging members, each pivotally mounted to one end thereof upon respective one of said shafts, said tire engaging members being movable from a lower, nonsupporting position to a raised, supporting position, said vehicle-supporting means being of such size as to be able to support a single vehicle tire; lock means interengaging between said vehicle-supporting means and said frame to maintain said vehicle-supporting means in the raised, vehicle-supporting position.
Claim 3
Dependent Claim
122 words
The dolly of claim 1 wherein said frame includes a main frame member and said shafts are secured to said main frame member, said shafts being secured to said main frame member in such a manner that said shafts extend a greater distance in one direction from said main frame member than in the other direction, said shaft extending a greater distance in the inboard direction than the outboard direction from said main frame member, so that the wheel mounted on said inboard end of said shaft is spaced farther from said main frame member than said wheel mounted on the outboard end of said shaft, said vehicle support means being movably mounted upon said frame inboard of said main frame member.
Claim 4
Dependent Claim
60 words
The dolly of claim 2 wherein said shafts are fixed with respect to said main frame member, and a tube is rotatably mounted upon each said shaft, a pair of arms secured to each said tube and a vehicle support pad pivotably mounted upon each said pair of arMs so that said vehicle-supporting pad can be pivoted around said shaft.
Claim 5
Dependent Claim
53 words
The dolly of claim 3 wherein a latch is movably secured to said arms, said latch being engageable with said main frame member so that when said vehicle support pad is in a raised position, said latch engages with said main frame member to retain said vehicle support pad in its raised position.
Claim 6
Dependent Claim
72 words
The dolly of claim 4 wherein said pad is pivotably supported upon said arms by means of a tubular pivot shaft, a pivot pin movably mounted in said tubular pivot shaft, a latch plate on said main frame member, said pivot pin being movable into an opening in said latch plate so that the pivot pin acts as said latch holding said vehicle support pad with respect to said main frame member.
Claim 7
Dependent Claim
72 words
The dolly of claim 2 wherein said frame includes cross members secured to said main frame member, said cross members engaging said shafts away from said main frame member so as to strengthen said shafts with respect to said main frame member, and to form a U-shaped frame, said U-shaped frame having an opening on the inboard side thereof of such size as to permit the dolly to embrace a vehicle wheel.
Claim 8
Dependent Claim
45 words
The dolly of claim 6 wherein said wheels are mounted upon said shafts inboard of said crosspiece and outboard of said main frame member, said vehicle-supporting means being pivotably mounted upon said shafts so that the vehicle-supporting means are movable with respect to said frame.
Claim 9
Dependent Claim
48 words
The dolly of claim 7 wherein said tire-engaging member comprise a tube rotatably mounted upon each of said shafts, an arm secured to each said tube, and a vehicle support pad secured to each said arm so that said vehicle support pads can be rotated about said shafts.
