Abstract
Abstract An automobile dolly for supporting the front end of a front wheel drive vehicle during transmission repair having a wheel supported frame sufficiently narrow to pass between the tracks of a vehicle hoist. In one embodiment front and rear tubular transverse supports are attached to the frame and spaced inward from and above the tracks, each support having a pair of opposed transversely adjustable sleeves telescopically engaging the tubular transverse supports and adapted for projecting over the tracks when positioned between the same. A vertically adjustable support member is attached to each opposed front sleeve and configured to abut and support the vehicle. In a second embodiment the frame pivotally mounts a single transverse support which includes adjustable sleeves adapted to telescopically project over the tracks. The sleeves have vertical support members for receiving and supporting the frame of the vehicle to permit the vehicle to be moved by means of the dolly.

Claim 1
Independent Claim
180 words
An automobile dolly for supporting the front end of a vehicle comprising: a frame member; a front wheel; a pair of spaced rear wheels both spaced from the front wheel; means for pivotally mounting the front and rear wheels to said frame member to permit movement of said frame member; handle means secured to said frame member to control the movement of said frame member; a first cross member secured to said frame member between said front and rear wheels but in close proximity to said rear wheels; a second cross member pivotally carried by said first cross member for rotational movement about a vertical axis; and A pair of vertical support members telescopically received in the opposite ends of said second cross member to permit alignment of said vertical support members with a predetermined location on the frame of the vehicle to be supported by said dolly, alignment being had by the telescopic engagement of said vertical support members with said second cross member and the pivotable movement of said second cross member with respect to said frame member.
Claim 2
Dependent Claim
180 words
An automobile dolly for supporting the front end of a vehicle comprising: a frame member; a front wheel; a pair of spaced rear wheels both spaced from the front wheel; means for pivotally mounting the front and rear wheels to said frame member to permit movement of said frame member; handle means secured to said frame member to control the movement of said frame member; a first cross member secured to said frame member between said front and rear wheels but in close proximity to said rear wheels; a second cross member pivotally carried by said first cross member for rotational movement about a vertical axis; and A pair of vertical support members telescopically received in the opposite ends of said second cross member to permit alignment of said vertical support members with a predetermined location on the frame of the vehicle to be supported by said dolly, alignment being had by the telescopic engagement of said vertical support members with said second cross member and the pivotable movement of said second cross member with respect to said frame member.
Claim 3
Dependent Claim
103 words
The automobile dolly defined in claim 1 further comprising: a mounting block adjustably locatable on the upper surfaces of said vertical support members, said mounting block having a vertically movable support pin biased to an upward extended position where the upper surface of said support pin is adapted to engage a predetermined location on said frame of said automobile when properly positioned with respect thereto, the lower end of said support pin engaging said predetermined locations on said vertical support members to retain said mounting block at said predetermined location; and spring means disposed in said mounting block for biasing said pin upwardly.
Claim 4
Dependent Claim
