Tire changer with combination wheel clamps and bead looseners

A device for clamping a wheel about the rim and loosening the bead of a tire attached thereto comprising:

• a table to support the wheel and tire;
• a plurality of wheel clamping shoes located on said table which are movable so as to radially converge and clamp upon the rim of the wheel;
• a support within and movable relative to each of said shoes, the relative motion being radial with respect to the wheel;
• a tongue pivotally located on at least one support;
• a biasing means interconnecting said support with said shoe to restrain relative motion until the movement of said shoes is impeded;
• and
• a means connected to said support to converge said shoes toward said rim whereby said shoes move toward said rim until impeded thereafter said biasing means is overcome causing said shoes to clamp said wheel and said tongue to pivot and be inserted between said bead and said rim to loosen the bead from the wheel.

A device for clamping a wheel about its rim and loosening the bead of a tire attached thereto comprising:

• a table having a support thereon to hold the tire and wheel above said table;
• a plurality of tracks on said table extending radially toward said wheel;
• a drive member movable along said tracks;
• a shoe slidable along said tracks having a projection thereon to hook the rim;
• a support member connected to said drive member;
• a biasing means interconnecting said support to said shoe;
• tongues mounted to at least some of said supports so as to pivotably extend from the projection;
• and
• means to move said drive members, supports and shoes convergingly along said tracks until the projections encounter sufficient resistance to result in the relative movement of the support against the biasing means causing said projections to firmly clasp the rim therebetween and said tongues to pivot and extend between the rim and the tire to loosen the bead of the tire.
