ABSTRACT:
A suspension type static balancing device for rotatable bodies such as automobile wheel and tire assemblies, the device comprising a suspended element which can be seated upon a horizontal surface and will have an annular flat face upon which a wheel to be balanced is placed with its hub orifice substantially concentric with the central orifice in the plate. A vertical tube protrudes upwardly through the orifice in the plate centrally of the orifice from the base of an inverted cone member having the annular plate connected to its rim. A flexible suspension cable has its lower end anchored within the lower portion of the tube and extends upwardly through the tube for attachment to an overhead support. The supported wheel is centered with the vertical tube for balancing by means of a centering member of inverted frustro-conical form slidably carried upon the tube and manually movable to closely fit within the hub orifice. Provision is made for the anchoring attachment of the lower end of the cable to be vertically adjusted, so as to adjust the sensitivity of the device to a satisfactory value.
