Abstract

Abstract An automobile dolly for supporting the front end of a front wheel drive vehicle during transmission repair. The dolly of the present invention comprises a wheel supported frame sufficiently narrow to pass between the tracks of a vehicle hoist. A rear tubular transverse support is attached to the frame and inward from and spaced above the tracks, with a pair of opposed transversely adjustable rear sleeves telescopically engaging the rear tubular transverse support and adjustably projecting over the tracks. A vertically adjustable support member is attached to each opposed rear sleeve and configured to abut and support the vehicle. A front tubular transverse support is spaced from the rear tubular transverse support and attached to the frame and is spaced inward from and above the tracks. A pair of opposed transversely adjustable front sleeves telescopingly engage the front tubular transverse support to adjustably project over the tracks. A vertically adjustable support member is attached to each opposed front sleeve and configured to abut and support the vehicle so that support of the vehicle's front end may be transferred from the hoist to the dolly and the vehicle moved using the dolly wheels during transmission repair.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 264 words
An automobile dolly for supporting the front end of a front wheel drive vehicle during transmission repair comprising: a base frame including a pair of spaced side members, a front cross member and a rear cross member extending between and joined to said side members to form a frame with an open center; wheel means attached to said base frame; a rear tubular transverse support resting upon and affixed to said spaced side members; a pair of opposed transversely adjustable rear sleeves telescopically engageably with said rear transverse tubular support; a rear vertical tube attached to an outer end of each rear sleeve; a rear support telescopingly engaged with each rear vertical tube; a pair of longitudinal tubes, each tube overlaying a side member and disposed in parallel abutment therewith, said longitudinal tubes extending from said rear transverse support to a point short of said front cross member; a pair of longitudinal sleeves telescopingly engageable with said longitudinal tubes; a front transverse tube extending between said longitudinal sleeves to joint them into a U-shaped piece telescopingly engageable with said longitudinal tubes; a pair of opposed transversely adjustable front sleeves telescopingly engageable with the ends of said front transverse tube; a front vertical tube attached to an outer end of each front sleeve; a front support telescopingly engaged with each front vertical tube; means for selectively adjusting the transverse spacing of said front and rear support members; means for selectively adjusting the height of said front and rear support members; and means for selectively adjusting the longitudinal spacing between said front and rear support members.
Claim 2
Dependent Claim 264 words
An automobile dolly for supporting the front end of a front wheel drive vehicle during transmission repair comprising: a base frame including a pair of spaced side members, a front cross member and a rear cross member extending between and joined to said side members to form a frame with an open center; wheel means attached to said base frame; a rear tubular transverse support resting upon and affixed to said spaced side members; a pair of opposed transversely adjustable rear sleeves telescopically engageably with said rear transverse tubular support; a rear vertical tube attached to an outer end of each rear sleeve; a rear support telescopingly engaged with each rear vertical tube; a pair of longitudinal tubes, each tube overlaying a side member and disposed in parallel abutment therewith, said longitudinal tubes extending from said rear transverse support to a point short of said front cross member; a pair of longitudinal sleeves telescopingly engageable with said longitudinal tubes; a front transverse tube extending between said longitudinal sleeves to joint them into a U-shaped piece telescopingly engageable with said longitudinal tubes; a pair of opposed transversely adjustable front sleeves telescopingly engageable with the ends of said front transverse tube; a front vertical tube attached to an outer end of each front sleeve; a front support telescopingly engaged with each front vertical tube; means for selectively adjusting the transverse spacing of said front and rear support members; means for selectively adjusting the height of said front and rear support members; and means for selectively adjusting the longitudinal spacing between said front and rear support members.
Claim 3
Dependent Claim 41 words
The automobile dolly as defined in claim 1 wherein the wheel means comprises: a pair of longitudinally aligned, spaced wheels attached to the ends of the rear cross member; and a pivotable castor wheel centrally attached to the front cross member.
Claim 4
Dependent Claim 77 words
The automobile dolly as defined in claim 2 further comprising: a pair of spaced apart forward extending rails attached to the castor of the pivotable castor wheel; a towing tongue inserted between said rails, an aperture formed in the towing tongue aligned with a pair of apertures in said rails and a pin engaging the aligned apertures to hingedly join the towing tongue to the castor; and whereby the pivotable castor wheel is made steerable and towable.
Claim 5
Dependent Claim 101 words
The automobile dolly as defined in claim 1 wherein the means for selectively adjusting the transverse spacing of said front and rear support members comprises; a plurality of transversely spaced apertures formed in an outer end of the front tubular transverse support and the rear tubular transverse support. an aperture formed in each front and rear transverse sleeve configured to selectively align with one of the corresponding plurality of transversely spaced apertures; and a first pin engageable with each of the aligned apertures to secure the front and rear transverse sleeves in place within the front and rear tubular transverse supports.
Claim 6
Dependent Claim 108 words
The automobile dolly as defined in claim 1 wherein the means for selectively adjusting the height of said front and rear support members comprises: a plurality of vertically spaced apertures formed in each front vertical sleeve and each rear vertical sleeve; a half round recess formed along an upper edge of each front vertical tube and rear vertical tube configured to selectively align with one of the plurality of vertically spaced apertures; and a second pin for each sleeve slidingly engaging the corresponding vertically spaced apertures and resting upon the recess to secure the front and rear vertical sleeves in position in the front and rear vertical tubes.
Claim 7
Dependent Claim 82 words
The automobile dolly as defined in claim 1 wherein the means for selectively adjusting the longitudinal spacing between the front support members and the rear support members comprises: a plurality of longitudinally spaced apertures formed in each of the longitudinal tubes; an aperture formed in each of the longitudinal sleeves configured to selectively align with one of the corresponding plurality of longitudinally spaced apertures; and a pin slidingly engaging the aligned apertures to secure the corresponding longitudinal sleeve to the longitudinal tube.
Claim 8
Dependent Claim 66 words
The automobile dolly as defined in claim 1 further comprising: a cap covering an upper end of each front and rear support; an opening formed in said cap; a flange complementary to the cap carried by each front and rear support member; and a dowel projecting from the flange slidingly engaging the opening in the cap whereby the front and rear support members are easily interchanged.
