Abstract
Abstract An apparatus for renovating tire inner liners comprises a wire brush attached at the end of a rotatable shaft and swivelably mounted within a turret mounted on a sleeve surrounding said shaft. This shaft and its surrounding sleeve are pivotally mounted on a fixed base for movement both horizontally and vertically to facilitate the egress of the brush to the inside of a tire casing. In operation, the wire brush is rotated by an electric motor and swiveled with the turret to abrade the inner surface of the tire casing and prepare it for application of a liquid air barrier coating.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
187 words
A tubeless tire renovating apparatus comprising: a. a fixed base member; b. a first U-shaped support yoke pivotably attached at its middle to said base member to rotate in a horizontal plane about said base; c. a second U-shaped support yoke pivotably attached at its ends to the ends of said first yoke whereby said second yoke may be moved relative to said first yoke in a vertical plane; d. a pair of cylindrical sleeves rigidly attached to the ends of said second yoke; e. a pair of rods passing through said sleeves and attached therein at their midpoints; f. a support carriage plate having guides for said rods attached thereto, thereby permitting sliding movement of said carriage parallel to said rods; g. motor mounted on said carriage plate for driving a rotatable shaft supported by bearings mounted on said carriage plate, said shaft extending beyond said plate; h. a wire brush driven by said rotatable shaft through a double set of bevel gears disposed therebetween, said wire brush swivelably mounted in a housing in fixed relation to said shaft and containing means for swiveling said brush.
