Abstract: A bead breaking device (10) to break a bead (71) from a rim (81) of a wheel (80), comprising an assembly (20, 90) for mounting the device upon a wheel; a first arm (40) pivotally connected to the assembly; means for rotating (50) the first arm; and a breaking tool (60), carried at one end of the first arm and rotatable therewith relative to the assembly. A method for breaking a tire bead from a rim of a wheel, comprises the steps of mounting a wheel and a tire on a bead breaking machine; locating a bead breaking device on the machine, the device providing a bead breaking tool and at least a first arm carrying the tool at one end; forcing the bead breaking tool between the bead of the tire and the rim at one point on the circumference of the rim; and rotating the first arm and bead breaking tool sufficiently to cause the tool to separate the seal between the bead and the rim.

Abstract: A center post tire changing apparatus for mounting or demounting a tire from a wheel includes an elongated support post having a wheel support assembly disposed on one end of the support post and a center post connected to and extending upwardly from the wheel support assembly and in coaxial alignment with the support post. A wheel securing assembly is disposed upon the center post, wherein the wheel is securely mounted on the center post between the wheel support assembly and the wheel securing assembly. A bead beaker is preferably permanently secured to the support post and is noted to be continuously adjustable thereon.

Abstract: A tool for use in conjunction with a center-post tire changing machine for mounting and demounting pneumatic tires from wheel rims includes an elongated shaft member having first and second ends wherein a portion of the elongated shaft member defines a main plane of the tool. A tire mounting portion at the first end includes a rounded first face forming a bead contact area, a flat second face forming a rim contact area, and a retaining knob protruding from the flat second face, the tire mounting portion being angularly offset from the main plane vertically by a first bend and horizontally by a second bend. A tire demounting portion at the second end includes a rounded first face forming a bead contact area, a flat second face forming a rim contact area, and a retaining knob protruding from the flat second face. The tire demounting portion is angularly offset both horizontally and vertically from the main plane by a third bend.
