ABSTRACT:
A machine frame includes a pair of upstanding frame members interconnected by a pair of telescopic members which include a power cylinder for moving the upstanding members towards and away from each other. A bead breaker arm includes a pair of hooks on one end, the bottom of which pivotally engages a pin on one of the upstanding members while the other hook movably engages another pin spaced above the first pin to allow the arm to move vertically within limits defined by the hook and the opposite end of a curved surface along which the second pin engages as the arm is raised and lowered. The outer free end of the arm includes a pivotal wedge member having an upwardly curved tapered end for engaging the rim and moving between the tire bead and the rim. The other upstanding frame member includes a rim holder for limiting the rim against vertical movement. A tire support cradle is formed from a plurality of arcuately arranged roller rods connected to one of the upstanding frame members and telescopically and rotatably engaging the other frame member to allow for rotation of the tire and inward and outward movement of the outer upstanding frame member relative to the inner upstanding frame member.
