ABSTRACT
Apparatus for use in measuring the camber and castor of a motor vehicle wheel comprising a main frame from which extends two projections each with an extremity to engage a part of a wheel assembly so that in use one extremity is located above the other, and calibration means adapted so that in use it indicates the amount of misalignment of said extremities from a position of vertical alignment.

Description
The present invention relates to apparatus for wheel aligning motor vehicles and more particularly, but not exclusively to apparatus for measuring the camber and/or castor of motor vehicle wheels.
Apparatus usually employed to measure and/or adjust the camber and castor of motor vehicle wheels is usually complex and accordingly is expensive and time-consuming to operate.
It is the object of the present invention to provide an apparatus to be used for the adjusting of the camber and/or castor of motor vehicle wheels, which apparatus is simple to manufacture and easy to use.
In accordance with an aspect of the invention there is provided apparatus for use in measuring the camber and castor of a motor vehicle wheel comprising: a main frame; two parallel generally co-extensive rods extend1ng from and at spaced locations on the main frame so as to be located within a single generally vertical plane; clamp means selectively slidably attaching the rods to the main frame so that said rods are movable along their longitudinal axes and in a direction normal to the , longitudinal axes of the rods so that the rods are movable relative to each other to adjust the,spacing between the ~ ' rods; abutment means on each rod at adjacent ends of the ~ -rods, said abutment means each havlng a planar end surface ~ , normal to the axes of the rods to enyage a suspension member of the vehicle; and calibrated means mounted on the main frame to determine the inclination of the rods to the horizontal when the rods are abutting a portion of the ~'.

Pivotally attached to portion 11 by means of nut 17 is indicator 20 to which is attached a spirit level 21, while marked on the portion 12 is a scale 22.
In operation the camber and castor of a motor vehicle wheel may be measured by adjusting the members 15 and 16 so that their points 24 are equally spaced from their respective clamp 13 or 14. Thereafter the points 24 are placed against portions of the wheel assembly at generally vertically aligned location, for instance, at upper and lowèr ball pivot points which support the wheel assembly when measuring castor and at disc or drum flange when measuring camber. Since the members 15 and 16 are parallel to the member 12 the adjustment of the indicator 20, by means of spirit level 21, so as to extend in a horizontal direction, indicates the camber or castor of the wheel on the scale 2. . ;
