  "abstract": "An improved tire changing tool for use in the repair or changing of pneumatic tires on vehicles having split rims. The tool includes a spider-like assemblage having a plurality of radially extending arms each of which is fitted with an adjustable pusher unit for engagement with the periphery of a split rim. The number of arms and the dimensions of the pusher unit transverse to the length of each arm is such that parts of a split rim having a diameter on the order of the diameter of the split rim are positively confined within the space defined by the arms, the pusher units and other portions of the split rim. Thus, such parts cannot fly off of split rims to strike the user of the tool to cause possible injury.",
  "claims": [
    "1. A tire repair tool for use in the repair or changing of pneumatic tires of vehicles employing split rims; said tire repair tool including a spider assemblage having means for positively confining the parts of a split rim to prevent injury to the user of the tool comprising: four equally spaced radially extending arms, each arm having a pusher unit mounted thereon, each pusher unit including an aperature for slidable receipt of the associated arm, means for locking the pusher unit at a desired location on the associated arm, and a notch-like split rim engaging surface extending generalLy transverse to the axis of said aperature; brace means extending from the center of said assemblage along a portion of the length of each arm, and means for securing said assemblage to a boom, at least some of the arms including means defining tool receiving aperatures extending generally transverse to the length of the associated arm so that a bar-like tool may be inserted in one of said tool receiving aperatures to assist in manipulating said tire repair tool when mounted on a boom.",
    "2. Apparatus according to claim 1 wherein each of said pusher units comprises a unitary construction having said aperture at one end and said split rim engaging surface at the other end and interconnecting diverging legs, said split rim engaging surface being located on the diverging ends of said legs and remote from said one end, and rigidifying means interconnecting said legs adjacent said split rim engaging surfaces."
