Abstract:
An annular ring-shaped run flat device is used in tires to permit continued use of the tire even when the tire is operating at low pressure or is completely deflated. This device is comprised of a rigid section and a non-rigid section. The tire, when it collapses, due to a reduction in pressure, comes to rest on the surface of the non-rigid, resilient, impact resistant section. This device is easy to assemble, can be used with conventional multi-piece rims, is light weight, durable and capable of absorbing impact under both inflated and deflated conditions. The device can also be used as a positive and non-positive bead spacer to prevent dismounting of the tire beads when tire pressure drops.
Abstract:
A pneumatic tire and wheel assembly of the drop center type is disclosed including an inflatable annular cord-reinforced tube for filling the well of the wheel. The uninflated diameter of the cord-reinforced annular tube is substantially equal to the diameter of the base of the wheel well but expands to a diameter greater than the diameter of the bead seats upon inflation.The foregoing abstract is not to be taken as limiting the invention of this application, and in order to understand the full nature and extent of the technical disclosure of this application, reference must be made to the accompanying drawings and the following detailed description.
Abstract:
A tire with conventional components having a pair of annular beads with different diameters, and contour lengths which are substantially equal. The contour lengths are referenced to the sidewalls of the tire and are measured along the neutral axis of the carcass plies between the beads and a plane containing the mid-circumferential centerline of the tread.
Abstract:
A bead retention system for mounting and retaining tires on a rim in which a band of resilient flexible material has a series of transverse bead separators mounted along its length at spaced-apart positions. The band has a length and configuration in the unstressed condition for positioning in a tire cavity prior to mounting of the tire on the rim. A cable connecting the ends of the band extends through a ratchet locking member and may be inserted through the valve hole of the rim whereby the band can be pulled down and locked in position around the rim after mounting of the tire on the rim.
Abstract:
A safety support for mounting on a split rim inside a tire chamber to resiliently support the tread portion of the tire in the deflated condition and maintain the bead portions of the tire in separated positions. The support is in the form of an annular ring of resilient material having a base with a relatively wide radially inner surface for seating on the rim and separating the bead portions. A flange extends radially inward from the radially inner surface of the base for gripping by the rim sections to seal the space within the tire and retain the ring on the rim. The radially outer portion of the support has a diameter less than the diameter of the tread portion of the tire in the deflated condition and greater than the diameter of the base portion. The base portion may be of greater width than the radially outer portion and be connected to the outer portion by an intermediate supporting portion of circumferentially spaced-apart radially extending ribs for cushioning the vehicle on which the tire, safety support and rim assembly are mounted.
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.
Abstract:
There is disclosed herein a method of manufacturing low aspect radial tires. The radial tires are mounted upon a bladder assembly during the time from the assembly of the tread reinforcing structure with the carcass until the vulcanization of the tire in a mold. Restrictor band material is wrapped around the tire to prevent circumferential growth of the tire beyond a predetermined diameter, so that the tire will not become too large to fit into the mold.
Abstract:
A segmental annular safety support having swivel hinged segments for mounting on a rim inside a tire chamber with at least one of said segments having resilient means at the inner periphery for compression between the rim and segment when the segments are latched together to provide preloaded clamping of the support on the rim.
Abstract:
A removable resilient shield is maintained proximate the sidewalls of a tire for off-the-road vehicles to protect this critical area of the tire from damage due to contact with external objects such as rocks. The shield is attached to the rim flange. The radially inner portion of the shield is discontinuous to prevent accumulation of debris between the shield and the sidewall of a tire mounted on the rim.
Abstract:
An implement providing an irrigator/evacuator primarily intended for use in connection with urological surgery, includes a reservoir connected to one side of the barrel of a pump having an outlet opening at one end. A compressible bulb attached to the end of the barrel opposite the outlet opening can be utilized to displace fluid within the implement outwardly through the outlet opening for irrigation purposes, and subsequently to draw fluid into the implement for evacuation purposes. A free piston is housed within the pump so as to freely movable along the length of the barrel. Fluid drawn into the implement causes movement of the piston to a retracted position, allowing substantially unrestricted passage of pieces of tissue or other material into the reservoir. The outward displacement of fluid from the implement, on the other hand, causes movement of the piston toward the outlet end of the barrel, in which position the piston effectively prevents the expulsion of tissue and the like from the implement, without significantly restricting fluid flow.
