ABSTRACT:
A suspension-type static wheel balancer for do-it-yourself mechanics including an upwardly-sloping conically-shaped body both centering and supporting the wheel through its center hub aperture in a generally horizontal position under the lifting point. The entire wheel and balancer assembly is supported by a flexible cable attached through a disk centrally attached inside the cone body and passing upwardly through the aperture in the upper end of the cone body for attachment to a suitable lifting means. After manual centering any imbalance condition is indicated when the wheel is lifted by a lack of centrality of the cable relative to the upper opening of the cone body. A ramification incorporates a means of adjusting the sensitivity of the balancer by vertically adjusting the universal pivot point relative to the center of gravity of the wheel.
