Abstract
Abstract This invention relates to a mounting of the pivot shaft for wheel support whereby the alignment of adjustment of vehicle wheels, in particular as to the camber, can be positively accomplished and maintained. The pivot shaft on which the pivoted arm is supported is mounted transversely in a frame of generally U-shaped cross section slidable in a box open at both ends, which latter is fixedly mounted on a bolt through the channel frame of the vehicle; the U-shaped frame for the pivot shaft has a threaded shaft extending from its base axially of the box and through a transverse plate fixed in the box and is held in place by a rotatable nut so held on the fixed plate that when the nut is turned the threaded shaft will travel through the nut and accordingly slides the U-shaped frame and the pivot shaft in the box in the direction desired for the adjustment of the wheel alignment.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
108 words
In an adjustable wheel pivot mounting, a bracket frame having parallel spaced guidewalls, means to mount the bracket frame on a frame member of a vehicle, a hollow pivot support frame having opposite walls slidable and non-rotatable in said bracket frame between said guidewalls, a wheel pivot shaft extended across the pivot support frame and held on the walls thereof transversely to said guidewalls, and coacting adjusting means connected to said frames and being manipulatable for moving said pivot support frame between said guidewalls in a direction at right angles to the pivot shaft relatively to said bracket frame, thereby to adjust the location of said pivot shaft.
Claim 2
Dependent Claim
108 words
In an adjustable wheel pivot mounting, a bracket frame having parallel spaced guidewalls, means to mount the bracket frame on a frame member of a vehicle, a hollow pivot support frame having opposite walls slidable and non-rotatable in said bracket frame between said guidewalls, a wheel pivot shaft extended across the pivot support frame and held on the walls thereof transversely to said guidewalls, and coacting adjusting means connected to said frames and being manipulatable for moving said pivot support frame between said guidewalls in a direction at right angles to the pivot shaft relatively to said bracket frame, thereby to adjust the location of said pivot shaft.
Claim 3
Dependent Claim
61 words
The adjustable wheel pivot mounting specified in claim 1, and said adjusting means including, a threaded member extended from said pivot support frame between said guidewalls, a rotatable threaded element held against relative movement on said bracket frame and threadedly engaging said threaded member, whereby said threaded member and said pivot support frame is shiftable between and parallel with said guidewalls.
Claim 4
Dependent Claim
63 words
The adjustable wheel pivot mounting specified in claim 2, and said pivot support frame being of substantially U-shaped cross section, Opposite legs of said support frame being slidable along the respective guidewalls, said pivot shaft being supported on said opposite legs of said pivot support frame, and said threaded member extending from the base of said pivot support frame of U-shaped cross section.
Claim 5
Dependent Claim
42 words
The adjustable wheel pivot mounting specified in claim 3, and a back plate on said bracket frame between said guide walls being spaced from the base of said pivot support frame, and said rotatable threaded element being supported on said back plate.
Claim 6
Dependent Claim
61 words
The adjustable wheel pivot mounting specified in claim 1, and said bracket frame being tubular, opposite side walls on said pivot support frame, said wheel pivot shaft extending across said pivot support frame, and being supported on said side walls, said side walls being slidable in said bracket frame in directions at right angles to the axis of said pivot shaft.
Claim 7
Dependent Claim
155 words
The adjustable wheel pivot mounting specified in claim 1, and said bracket frame being of substantially rectangular cross-section, and being open at least at one end thereof, said pivot support frame being of substantially U-shaped cross section the legs thereof extending toward said open end and being slidable in said bracket frame, said wheel pivot shaft extending across said pivot support frame and being supported on the legs of said U-shaped support frame, said coacting adjusting means including a threaded member extending from the base of said U-shaped support oppositely to said legs, a fixed cross member across said bracket frame between said U-shaped frame and the other end of said bracket frame, a threaded adjustor element rotatably held in said cross member against axial movement and engageable by said threaded member whereby the rotating of adjustor element moves said threaded member and said U-shaped frame axially to adjust the position of said pivot shaft.
Claim 8
Dependent Claim
32 words
The adjustable wheel support mounting specified in claim 6, and a locking element releasably held on said cross member and engageable with said adjustor element to hold said adjustor element against rotation.
