  • Patent number: 4157726
    Abstract: A segmental annular tire safety support for mounting on a wheel rim to support a pneumatic tire in the deflated condition. The safety support includes a segmental curved member having a generally cylindrical radially outer supporting surface of revolution with a substantially constant radius circumferentially of the tire safety support. The ends of the curved member have radially outer end surfaces which are relatively flat and are spaced from the axis of the support a distance less than the length of the radius of the outer supporting surface of the curved member to reduce the stresses generated at the end edges and to provide warning vibrations and noise during operation of the tire in the deflated condition.

  • Patent number: 4157107
    Abstract: The drawings disclose a pneumatic tubeless tire including either one or two load support running bands adapted to support the weight of a vehicle should the tire become deflated. The circumferential centers of the support bands are substantially coplanar with the planes of respective annular tire beads. In one embodiment the applicable bead is a third bead integrally formed adjacent one of the normal beads on the inner surface of the beaded edge of the tire. Double rows of circumferentially oriented, spaced apart tension spokes, with alternate pairs thereof oppositely angularly disposed so as to cross one another, rigidly connect each support band to the respective annular bead. An annular ridge is formed on the rim adjacent the inner edge of each beaded end to retain the beaded ends in position during deflated tire conditions.

  • Patent number: 4155392
    Abstract: A method of increasing the tread and sidewall life of a radial belted pneumatic tire with an open end belt in which the tire is cured in a mold with the central portion of the tread in a curved configuration having the same tread radius and the margins of the tread having an increased tread radius. The sidewalls are cured with the maximum sectional width of the tire spaced from the bead baseline a predetermined distance greater than 55 percent of the maximum section height of the tire so that upon inflation of the completely manufactured tire to design inflation pressure, the tread surface of the tire will have a substantially constant tread radius across the tread profile for even wear of the tread and the tension in the sidewalls will be reduced for increased life of the tire.

  • Patent number: 4155388
    Abstract: A plurality of traction devices are positioned transversely in spaced relation on a tire tread. Each traction device has a first end portion arranged to be guided into one of a plurality of troughs that are positioned on the periphery of a circular member mounted to the unexposed or inside rim of a vehicle wheel. The troughs are separated by crests to form a wave-like configuration on the periphery of the circular member. The first end portion is guided into a trough without the need to visually locate the point of attachment on the circular member. A portion of the first end portion is too large to pass through the trough and serves to secure the traction device to the inside circular member. A second end portion of the traction device is secured on the opposite side of the tire by connection to a second circular member or to the ends of the other traction devices to tightly position an antiskid body portion of the traction device on the tire tread.

  • Patent number: 4154279
    Abstract: Apparatus for remotely controlling the internal pressure in a pneumatic tire, in which the inside of a pneumatic chamber mounted on a wheel is divided into a first chamber communicating with a fluid-supply source and a second chamber communicating with an air space in the tire by a diaphragm made of a flexible material. In an operation controlled from a vehicle cab, a fluid is introduced into the first chamber, thus compressing the second chamber so as to change the volume thereof, and thereby control the pressure in the air space with the tire by controlling the pressure in said second chamber.

  • Patent number: 4151870
    Abstract: A wheel with a rim having a drop center well and a retainer member for a tubeless pneumatic tire. In use the bead of the inflated tire is prevented from moving inwardly off the bear seat and into the drop center well of the rim by the retainer member which is fixed to the rim axially inwardly of and adjacent a bead of the tire. If during mounting and inflation of the tire a bead thereof becomes caught on the retainer, a gas bleed passage through the retainer prevents the tire from being inflated while the bead is caught thereon, thereby preventing damage to the bead of the tire and minimizing the risk of personal injury.

  • Patent number: 4149579
    Abstract: A pneumatic tire, after manufacture, is provided with a propellant material and a foam forming sealant material in its interior pressurizable space. The propellant and sealant are isolated from each other during normal running conditions of the tire and have no significant effect on the normal running characteristics of the tire. When a tire fails due to a puncture or the like, a loss of tire pressure and/or collapse of the tire structure and/or heat build up in the bead area due to friction permit the propellant and the foam forming materials to interreact.In one embodiment of the invention the propellant and sealant are enclosed in separate chambers of a plurality of dual-chamber containers secured to the bead portion of the tire and/or a rim base. In other embodiments a plurality of mono-chamber containers house one of the materials, the other material being uncontained in the pressurizable space.

  • Patent number: 4146076
    Abstract: A tire-slip preventing device or "chain" for a vehicle tire comprise a ladder-like arrangement of cross belts attached to two parallel cords. The belts and cords are made from an easily deformable material so that the device may be wrapped around a tire. Rotatable discs are mounted at each end of each cross belt between the cross belts and the side walls of the tire to reduce wear on the side walls as the belts move relative thereto. The cross belts may be permanently attached to both parallel cords, or permanently attached at one end to one cord and detachably attached at the other end to the other cord.

  • Patent number: 4144920
    Abstract: A traction increasing chain for vehicular tires that may be installed thereon without moving the tire relative to the surface supporting it. The chain provides plural rigid side elements articulately interconnected and carrying cross-chains, all so configured that when installed on a tire the cross-chains will cover a portion, but not the supported portion, of the peripheral surface of the tire. A medial fastening linkage maintains the chain on the tire during usage.

  • Patent number: 4143600
    Abstract: A chain attachment structure interconnects the end of a chain to the takeup drum of a winch or hoist so that the chain load is applied directly to an integral part of the drum even if the chain is fully unwound. A recess extends inward from the periphery of the drum and includes a pair of spaced walls. A lug integral with one wall extends toward the opposite wall. The space between the lug and the opposite wall defines a path for inserting a chain link into the recess and over the lug. A keeper inserted into the path prevents removal of the link from the lug.

  • Patent number: 4140167
    Abstract: This disclosure relates to a sealant material to be primarily used in pneumatic tires to seal punctures made by external objects, such as nails. The sealant may be a single layer or a laminate of sealant layer and covered layers. The sealant layer contains a material that is at least partially degraded by irradiation or heat in the presence of a peroxide. The laminate may be in sheet or strip form with various cross-sectional shapes. The layers in the laminate comprise rubber compounds, some of which may contain agents which either assist or retard cure by irradiation so that the layers will have different physical characteristics during the manufacture of end products containing the laminate. The laminate may be cured by any known method, either irradiation or thermal, after its assembly into the final product.
