ABSTRACT:
A tire bead breaking tool has a primary frame with a stem segment and a perpendicular retaining segment. A sliding member slides parallel to this stem segment. A threaded engagement bolt is used to adjust and secure the relative position of the sliding member with respect to the primary frame. A parallel arm is connected through a slot in the stem segment to the sliding member, and translates parallel to the stem segment as the position of the sliding member is adjusted by the engagement bolt. A second, hinged arm is pivotally attached to the end of the parallel arm distal from the cross segment. An actuating bolt is employed to pivot this hinged arm with respect to the parallel arm.
