ABSTRACT:
A carrier for inflatable pneumatic tires is supported for tilting travel about a substantially vertical axis upon an arcuately spherical universal pivot resting upon a seat having a corresponding sphericity. The seat surmounts a pedestal, and the pedestal and carrier are jointly formed with an air conducting means, the continuity of which is interruptible, to admit air to and from a tire mounted for balancing upon the carrier, to inflate and deflate such tire. The pedestal surmounts a fluid motor provided with two pistons in tandem: one piston carries an actuating rod to operate a valve to admit air to a tire prior to balancing, and to resist escape of air from an inflated tire on the carrier during balancing. The carrier is equipped with a lower rim element to engage a lower bead of a tire and an upper rim element to engage an upper bead of a tire. The upper rim element is removable. A carriage means is provided having travel to advance the upper rim element for deposit upon the carrier to retain a tire thereon, and alternatively, to remove and retract the upper rim element from the carrier to afford loading and unloading of a tire upon the carrier. The fluid motor rests on the upper surface of a housing, which housing also supports a frame or superstructure from which said carriage means is dependent.
