Abstract
An apparatus for removing the rubber tire casing from the steel rim of an automobile wheel which comprises a set of hydraulic cylinders and wedge shaped members which simultaneously converge on the tire casing and wheel to deform the tire rim into the figure of a three-leaf clover so that the tire rim can easily be removed from the inside of the casing. The wedge shaped member includes means for gripping a tire.
Claims7
An apparatus for removing a tire casing from a tire rim comprising:
- a frame for supporting a tire casing and a tire rim;
- a first power actuated member mounted on said frame, said power actuated member having a wedge-shaped elongated means for deforming said tire rim through said tire casing;
- a second power actuated member mounted on said frame, said power actuated member having a wedge-shaped elongated means for deforming said tire rim through said tire casing;
- a third power actuated member mounted on said frame, said third power actuated member having a wedge-shaped elongated means for deforming said tire rim through said tire casing;
- said first power actuated member, said second power actuated member and said third power actuated member coacting so that said wedge-shaped elongated means for deforming said tire rim on each of said power actuated members converge toward a central point to deform said tire rim located in a central position between said first power actuated member, said second power actuated member and said third power actuated member and thereby allow said tire casing to be removed from said rim.
The process of recycling a circular-shaped wheel having a circular-shaped tire casing thereon comprising the steps of:
- placing the wheel with a tire casing thereon on a support surface;
- directing deforming members radially inward over the support surface and against the tire casing until the circular-shaped wheel located in the tire casing has been deformed to a non-circular shape;
- retracting the deforming members to allow the tire casing to return to its normal circular shape;
- and
- separating the tire casing from the deformed wheel.
