Mobile bead breaker

A mobile tire bead breaking apparatus, comprising:

• a frame affixed to a mobile base, said frame including a first housing and a second housing, said first and second housings being separated by a sliding wall with an opening therein;
• a spider assembly comprising a plurality of legs extending outward from a central hub, each of said legs further includes an engagement member;
• means for adjusting said engagement member's position along the length of each of said engagement member's respective one of said plurality of legs;
• hydraulic means for driving said spider assembly toward and forcing engagement with a tire requiring repair to effectuate breaking of said tire's bead at at least one position about the rim of said tire and wherein said hydraulic means includes a piston, said piston extending from said first housing through said opening and into said second housing;
• and
• wherein said spider assembly is affixed to an end of said piston in said second housing.

A method for breaking a tire bead, comprising the steps of:

• positioning a tire within a bead breaking apparatus, said apparatus comprising:
• a frame having a first and second housing, said first and second housing being separated by a sliding wall with an opening therein and said fame being affixed to a mobile base,
• a spider assembly comprising a plurality of legs extending outward from a central hub, wherein each of said legs further includes an engagement member,
• means for adjusting the position of each respective one of said engagement members along the length of its respective one of said plurality of legs, and
• hydraulic means;
• adjusting said spider assembly and said hydraulic means vertically within said frame, said vertical adjustment being achieved through movement of said spider assembly and said hydraulic means along a threaded rod;
• adjusting each of said engagement members for interaction with the bead of said tire;
• and
• initiating said hydraulic means from said first housing so as to effectuate the movement of said spider assembly in said second housing towards said tire and causing the breaking of said tire bead at at least one location about the rim of said tire.
