ABSTRACT:
A suspension type portable wheel-balancer for "do-it-yourself" automobile owners includes a vertical hollow shaft with a plate member threadedly adjustable at a given horizontal level on the shaft. A suspending wire is actually secured in the interior of the shaft and extends out the top where it may be suspended from any appropriate fixture. The plate member includes three cam members equally radially spaced from the axis of the shaft serving to engage the inner periphery of the hub opening of the automobile owner's wheel to position the wheel in exact coaxial alignment with the axis of the hollow shaft and suspending wire. Each cam member is eccentrically rotatably mounted so that the radial distance of the radially most distant points of the cam members can be adjusted and locked in place to correspond to the specific radius of the hub opening of the automobile owner's wheels.
