Abstract
A target structure for use with an alignment apparatus, such as a line of sight alignment apparatus for detecting the alignment of wheels of vehicles such as automobiles, truck tractors and trailers comprises an adjustable, wheel engaging and target supporting structure mountable upon a vehicle wheel rim. The target structure has an inner wheel mounting member with upper and lower arm members extending therefrom and engageable with the vehicle wheel rim. An outer target mounting member is pivotally connected to the inner wheel mounting member through coaxial center portions thereof for relative rotation of the outer target mounting member relative to the inner wheel mounting member. The outer target mounting member has spaced shaft members extended outwardly of the wheel and holding a plurality of targets at cardinal points around the wheel, the targets providing scales for determining the angular position of the vehicle wheels for conventional measurements such as caster, camber, toe and kingpin inclination. A sighting instrument establishes a line of sight parallel to and longitudinally spaced from the vehicle and which is directed toward a target and impinges upon a discrete mark on the scale thereof. Comparison of the points of impingement upon targets located at opposite cardinal points of the wheel establishes angular relations therebetween which correspond to alignment measurements.
