Abstract: Wheel balancers and methods of their use are disclosed. One wheel balancer includes a cable and a base. The cable has a support end for being fastened to a support. The base is configured for receipt inside a wheel, and the base has proximal and distal ends and a hollow interior area for passing the cable therethrough. The cable passes through the base interior area and is operatively coupled to the base such that a distance between the cable support end and the base distal end is generally constant when the cable is extended. A pivot point for the cable is movable relative to the base between the base distal end and the cable support end.

Abstract: A balancing device for a wheel and tire assembly has an elongate cylinder with an upper end, a lower end, an exterior surface and male threads formed on the exterior surface. A longitudinal cylinder bore extends axially through the cylinder and receives therethrough a suspension cord. The cord has a stop element at a support end extending beyond the lower end of the cylinder for supporting the cylinder. A support member has a wheel support flange and at least a first wheel hub centering section extending from the support flange. The centering section has a fixed diameter adapted to accommodate a particular diameter wheel hub opening of the wheel and tire assembly. An axial bore is formed through the support member and has female threads formed internally in the bore which correspond to the male threads of the cylinder.

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.

Abstract: The device described is designed to balance wheels and comprises a tripod, an element sliding vertically and mounted upon the tripod, a supporting element serving to support the wheel to be balanced and supported, in turn, in one instance, by the vertically-sliding element, a suspension element mounted upon the tripod and comprising a lever extending above the supporting element, a connecting element uniting the supporting element to the lever and allowing it, in a second instance, to be supported in free suspension upon being released from the vertically-sliding element. A first reference mark is associated with the connecting element, and a second reference mark is associated with the supporting element. Wheel balancing is carried out by adding weights to the wheel until the two reference marks coincide.

Abstract: This disclosure relates to an improved balancing apparatus and method which is especially useful for balancing tires for cars, trucks, etc. The improved balancing apparatus of this disclosure comprises a lifting mechanism including object holding elements for lifting and holding the object or tire that is to be balanced, balance indicating elements for indicating the extent that the object or tire to be balanced is out of balance, and X-Y adjusting elements which are connected to the lifting elements and provides a free-floating arrangement for the balancing of the object or tire. In the disclosed embodiment of balancing a tire, the improved balancing apparatus is coupled or connected to the hub of a tire by means of bolts which releasably connect a plate located at the bottom of the lifting elements and the hub of the tire to be balanced.

Abstract: A wheel balancing tool having a support cable that partially extends into a hollow shaft to a suspension point coincident with the tube axis, two wheel adapters threaded onto the tube, and an annular magnifying indicator attached to the cable juxtaposed an indicator plate attached to the tube, the suspension point adjustable within the tube by means of a rod having an end portion extending into the tube to define the suspension point and a stop means attached to the rod for adjusting entry of the rod into the tube.

Abstract: A pendently suspended instrument for indicating the balance condition of a generally horizontal centrally apertured wheel includes a wheel support member having an upwardly facing surface for engaging the bottom side of the wheel. An elongated tube extends upward from the surface and a line is trained through the tube and secured to a member threaded in the center of the tire support member and tube for enabling vertical adjustment of the effective point of attachment of the line to the wheel support member. The upper end of the line is configured for attachment to an elevated support. A spring loaded wheel centering element, of upwardly converging shape, is carried slideably at the center of the wheel support member. The upwardly converging shape is produced by a plurality of angularly spaced apart triangular blades projecting upward from the wheel centering element and passing slideably through radially elongated slots in the wheel support member.

Abstract: A rotor is suspended from a body member which is mounted by two sets of bearings for substantially free pivotable movement about two orthogonally disposed intersecting axes, the axis of rotation of the rotor intersects the point of intersection of the two bearing axes, and a level indicating device is mounted to the body member.

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.

Abstract: An apparatus for balancing automotive wheels consisting of a horizontal support plate adapted to be disposed beneath the central wheel disc, a flexible cable affixed to the support plate to extend upwardly through the central hub aperture of the wheel disc, apparatus for centering the wheel accurately concentrically with the cable, and a gauge member fixed to the support plate and having an aperture spaced above and concentric with the attachment of the cable to the plate, the cable extending through the aperture and being suspended from a higher point to support the wheel, a balanced condition being indicated when the cable is centered in the aperture.

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.
