ABSTRACT OF THE DISCLOSURE: The present invention discloses an apparatus for removing a multi-section core from a vehicle tire and the apparatus includes a frame which pivotally mounts a support table so the support table can be moved between a first position, in which it is generally horizontal, to a second position, in which it is at an acute angle to the horizontal. The support table carries roller means which are adapted to engage a sidewall of and rotatably support a tire in a position with the axis of the tire generally at a right angle to the support table. A core clamp is positioned within the circumferential confines of the tire when it is supported by the rollers in the horizontal position of the support table and the core clamp is adapted to move between first and second longitudinal positions. The core clamp has jaws thereon, which are adapted to move between open and closed positions to grasp a selected section of a multi-section core and longitudinal movement of the core clamp causes the selected section of the core to be pulled from the tire in a direction generally parallel to the support table and in a diametral direction in relation to the tire. A backup support is provided for engaging a portion of the tread area of the tire to prevent movement of the tire when the core clamp is removing a core section from the tire. A rotatable spindle, which is movable between first and second positions, is pro- vided to engage a portion of the tread area of the tire at a position generally diametrically opposed from the backup sup- port. The spindle rotates the tire to desired rotational positions to properly position the various core section- so they can be engaged by the jaws of the core clamp. Motive power means are provided in the apparatus to cause all of the aforemen- tioned movements and to cause rotation of the spindle.
