ABSTRACT:
Apparatus usable with a tire changing machine includes a protective arm that may be pivoted about a shaft having an axis that is generally parallel to the radial axis of the wheel and tire assembly when positioned in the tire changing machine. A first section of the arm has one end mounted to the shaft so that the first section may be pivoted substantially in a plane perpendicular to the shaft. At the second end of the first section the arm extends in a section direction generally perpendicular to the first section. Pivoting of the arm permits the second section of the arm to be adjacent, and substantially parallel, to the circumferential surface of the tire and the first section to be adjacent, and substantially parallel, to the side wall surface of the tire. The arm thereby forms a safety barrier against the release of components of the wheel and tire assembly. The arm includes an additional portion that interacts with a safety latch that may be positioned on the tire changing apparatus to lock the arm in an engaged position and to activate pressurize air flow.
