Abstract:
A semi-pneumatic tire body for assembly to the rim of a wheel comprises spaced tread and root portions interconnected with spaced sidewalls to define an annular cavity. An annular load-bearing rib is connected to the root portion and extends radially toward the tread portion to be normally spaced apart from the tread portion in the unloaded state in order to establish communication between the internal chambers of the tire for free gaseous interchange and for free response of the tire to load forces.
Abstract:
A method of manufacturing tubular tires for bicycles and motorcycles, includes the steps of:laying bead steel wires longitudinally on a first or inner sheet of a tire casing and adjacent the edges thereof;folding the longitudinal marginal portions of the first or inner sheet of the casing around the bead wires in order to cover the wires completely;laying a second or intermediate sheet on top of the first or inner sheet, the longitudinal edges of the second sheet projecting well beyond the in-turned longitudinal edges of the first sheet;laying a casing tread on the thus superposed sheets;shaping the tire assembly thus obtained by imparting a horseshoe configuration thereto, as seen in cross-section;introducing an uncured inner air tube into the casing;closing the tire by assembling by welding the side edges of the second or intermediate sheet projecting from the casing; andvulcanizing the assembly.
Abstract:
A method for mounting a closed torous tire on a rim by withdrawing a volume of air from the tire, thereafter positioning the tire on the rim, and passing a volume of fluid into the tire.
Abstract:
A vehicular wheel and pneumatic tire assembly including a wheel portion, a tire-carcass portion and a separate tread band portion installed over the uninflated carcass-periphery, and in which the carcass portion is molded into a convoluted shape, when uninflated, that provides its easy stretching over the outside diameter of the wheel and, on application of an inflation pressure, simultaneously ensures both the outward expansion of the carcass-periphery and the inward contraction of the carcassinside diameter for respective tight-fitting engagement with, and assembly to, the tread band and wheel portions.
Abstract:
A vehicular tire having integral tread and carcass portions molded into a closed, toroidal configuration and further formed into a convoluted shape, when uninflated, both for providing and facilitating its stretching over the outside diameter of a mounted wheel, and for positively controlling and urging movement of the carcass-inside diameter in an inward contracting direction only to a gripping position with either the specially contoured wheel rim or adapter ring element mounted thereto.
Abstract:
A filament wound aircraft tire of the toroidal type which includes annular fabric strips positioned between the circular piles of the carcass in the heel or rim area, reinforcing the heel and adjacent rim edge increasing the strength and modulus of the tire carcass in this flexure area, and preventing flexure and compression fatigue failures of the carcass piles in these highly stressed areas. This invention constitutes an important improvement on my invention disclosed in my (T. J. Reinhart, Jr.) U.S. Pat. No. 3,171,462 for Toroidal Pneumatic Tire, dated Mar. 2, 1965, and having for an object the provision of means to increase the strength and modulus of the toroidal tire carcass in the area of the reinforcing ring or heel bead, adjacent the outer edges of the split rim or wheel.
