Abstract
Hand operated mechanism for breaking loose the beads of a tire mounted on a wheel having an interior annulus and rim flange adjacent a bead seat for receiving the tire bead includes a platform for supporting the wheel and tire, a linkage-supporting column extending upwardly from the platform, a pair of operators and supporting linkage therebetween supported by the column and being operatively interconnected for the selective manual movement of each operator, a bead breaking shoe supported by one of the operators, and a wedging shoe supported by the other of the operators. The linkage provides guided movement for leading each shoe to working positions at diametrically opposite sides of the peripheral line of joinder between wheel and tire and for causing the bead breaking shoe to move into engagement with the wheel and tire for the displacement of the bead from the associated rim bead seat toward the interior annulus of the rim as the opposite side of the rim is held in wedged tight position in situ.
