Abstract: A simple low cost building drum, free of axially movable parts for building tires and cylindrical articles having inextensible beads of given diameter therein but spaced axially any selected distance apart, has a single axially and circumferentially continuous radial expandable membrane overlying a thick-walled cylinder of deformable rubbery material the full axial length of which is expandable radially to wrap the membrane against beads placed about the drum and to divide the membrane into a non-inflatable center section and two inflatable end sections each axially outboard of a respective bead. The thick-walled cylinder is expanded radially by inflating an axially extending cylindrical sleeve within control members in the form of four semi-cylindrical strips which prevent bulging outward of the central portion of the thick-walled cylinder and which engage cylindrical flanges of a pair of end rings spaced along the drum's center shaft.

Abstract: Non-destructive examination of an article, particularly a tire for the presence, and particularly the depth below the surface, of an anomaly such as a discontinuity, void or foreign matter inclusion, employs ultrasonic energy. A transmitter of ultrasonic energy is disposed normal to the touching the surface of the article to be examined so as to feed ultrasonic energy thereinto. Ultrasonic energy receivers spaced apart from each other and from the trasmitter receive ultrasonic energy emergent or radiated from the surface of the article. With the tire, or other article, moving at a constant rate relative to the transmitter and receivers, a subsurface anomaly occludes or interrupts the energy beamed to the first receiver and then to the second. The time lapse and distance traveled between the two interruptions are proportional to the depth below the surface of the anomaly causing the interruptions. The energy received including the successive interruptions is displayed on an oscillograph.

Abstract: An energy absorber comprises an elastomeric member in a substantially trapezoidal configuration, a piston connected to the apex of the trapezoid, and piston retaining and mounting supports. The elastomer absorbs energy by virtue of its inclined buckling columns forming the sides of the trapezoid while the piston is forced to move in a substantially horizontal plane by the piston retaining and mounting supports. The energy absorber, when applied to vehicle applications, provides a bumper mount that accepts frontal and lateral force impact and lends itself to bumper jacking and towing forces.

Abstract: A closed torus tire in which the cord or wire reinforcement ply, or plies, surround the inflation chamber which can retain pressure without being mounted on a wheel. The reinforcement ply is continuous circumferentially of the tire and axially in the crown and sidewalls. The circumferential ply edges are lap-spliced in the inner wheel-engaging part, rather than being folded around bead cores. The tire is made without use of a building core of any kind, thus avoiding the cost and difficulty of removing such core from the completed tire. The tire is made by wrapping the reinforcement ply, or plies, about a cylindrical drum to form a sleeve. An inner liner is then wrapped about the sleeve, a reversal of normal tire building practice. One circumfferential edge of the sleeve is then moved outward and axially over the remaining sleeve, beyond the other, unmoved edge. The one edge is then moved inward and axially under the other edge to form the lapped splice.

Abstract: A removable tread installed as an annular belt about the circumference of a tire carcass. The inner surface of the removable tread belt and the outer surface of the tire carcass have an interengaging pattern to interlock the two. The removable tread belt has a plurality of axially oriented metal bars and an inextensible circumferential belt radially outwardly from the bars. The cross-section of the bars is substantially T-shaped, and the bars are provided with enlarged portions at each end. The ends of the bars extend outwardly to a point at least equal to the widest portion of the tire carcass sidewall. The bars and the inextensible belt are encapsulated in a matrix of rubber, which has a tread pattern on its outer circumferential surface.

Each has a fixed diameter cylindrical portion and a portion variable in diameter to provide an extension of the cylindrical surface expandable to conic form. An array of fingers are pivotally secured to swing in radial planes to provide the variable diameter portions and are actuated by inflatable sleeves. The fingers are notched to provide a locating groove for the wire ring at the end of the air spring. Ply endings are folded about the wire ring by a second inflatable sleeve or bladder.

The fluid may be released by an increase in temperature softening a plug in the wall or the adhesive in a seam between walls of the bag. The fluid may also be released by the rupture of a flexible tube extending from the bag to the radially outer surface of the stabilizer ring.

Abstract: A coordinated method and apparatus system for concurrently building an endless band and an endless inextensible belt, transferring the band coaxially of itself to a carcass forming and shaping drum, enfolding beads in inwardly turned ends of such band to form a carcass, then shaping the carcass while swinging the drum about a vertical axis to transfer the endless belt coaxially of itself and of the shaped carcass. The apparatus includes a band building drum with cooperating ply stock servicer for building the tire band and a belt building drum also with a cooperating servicer for supplying belt ply stock and, optionally, tread stock. Axes of the band drum and belt drum are disposed to intersect a vertical axis about which a turret mounted carcass forming drum swings into alternate coaxial alignment with the band building drum and the belt building drum.

Abstract: Stitchers for consolidating tire building components successively wrapped on a building drum comprise multiple thin or narrow annular discs in side-by-side array. Each is free independently and individually to rotate about an axis common to the discs in response to the rotation of the building drum, and to be displaced normal to such axis by differing radial elevation of the components relative to the surface of the drum. Uniformly distributed pressure of the discs on the components along the contact zone is obtained by an inflatable cushion extending through the discs and acting on them individually. Thin inner plates disposed respectively within each disc rotatably support the discs and transfer the stitching forces from the cushion to individual discs.
