Abstract
Abstract A linear tire and wheel assembly comprising a hub having spaced flanges on which are mounted an inner tube surrounded by a jacket over which a tire casing is mounted so that inflation of the inner tube results in the formation of a tire mounted on said hub. The jacket is made of flexible material which takes a predetermined shape when enlarged by the inflation of the inner tube. Air under pressure is supplied through one of the flanges.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
242 words
A wheel and tire assembly for a vehicle comprising: a. means forming a cylindrical hub; b. a pair of spaced flanges mounted on said hub, each of said flanges including a cylindrical collar; c. an inner liner comprising a continuous sheet of inflatable material surrounding and extending between the collars of said flanges; d. jacket means surrounding said inner liner capable of taking a predetermined shape upon being expanded by the inflation of said continuous sheet; e. an outer tire casing means enclosing said jacket means for being expanded into the shape of said jacket means upon the latter being expanded by the inflation of said inner liner and thereafter functioning as a tire; f. sealing means mounted on each said collar to prevent air from escaping from within said inner liner; g. opening means in one of said flanges for permitting gas under pressure to be injected into said inner liner for inflation thereof; h. said sealing means comprising external bead means for retaining said inner liner, jacket means, and casing means on said flanges and preventing loss of air under pressure from said inner liner; i. said external bead means comprising straps for clamping the ends of said inner liner, jacket means and casing means on each said collar and; j. said opening means comprising a passageway to permit gas under pressure to be injected, said passageway being sealed closed by tightening the strap on the flange containing said passageway.
Claim 2
Dependent Claim
242 words
A wheel and tire assembly for a vehicle comprising: a. means forming a cylindrical hub; b. a pair of spaced flanges mounted on said hub, each of said flanges including a cylindrical collar; c. an inner liner comprising a continuous sheet of inflatable material surrounding and extending between the collars of said flanges; d. jacket means surrounding said inner liner capable of taking a predetermined shape upon being expanded by the inflation of said continuous sheet; e. an outer tire casing means enclosing said jacket means for being expanded into the shape of said jacket means upon the latter being expanded by the inflation of said inner liner and thereafter functioning as a tire; f. sealing means mounted on each said collar to prevent air from escaping from within said inner liner; g. opening means in one of said flanges for permitting gas under pressure to be injected into said inner liner for inflation thereof; h. said sealing means comprising external bead means for retaining said inner liner, jacket means, and casing means on said flanges and preventing loss of air under pressure from said inner liner; i. said external bead means comprising straps for clamping the ends of said inner liner, jacket means and casing means on each said collar and; j. said opening means comprising a passageway to permit gas under pressure to be injected, said passageway being sealed closed by tightening the strap on the flange containing said passageway.
Claim 3
Dependent Claim
180 words
A wheel and tire assembly for a vehicle comprising: a. means forming a cylindrical hub; b. a pair of spaced flanges mounted on said hub, each of said flanges including a cylindrical collar having a first diameter and a sleeve of a smaller second diameter, the sleeve of each of said flanges facing each other; c. jacket means comprising a continuous sheet of inflatable material having a predetermined shape upon being inflated surrounding said hub and extending over the sleeves facing each other; d. an outer tire casing means enclosing said jacket means, forming a space therebetween, and extending over the cylindrical collar of each of the flanges for being expanded into the shape of said jacket means upon the jacket means being inflated; e. sealing means mounted on each said sleeve to prevent air from escaping from within said jacket means; f. means for clamping the ends of said tire casing means on each said collar; and g. means in one of said flanges for permitting gas under pressure to be injected into said jacket means for inflation thereof.
Claim 4
Dependent Claim
180 words
A wheel and tire assembly for a vehicle comprising: a. means forming a cylindrical hub; b. a pair of spaced flanges mounted on said hub, each of said flanges including a cylindrical collar having a first diameter and a sleeve of a smaller second diameter, the sleeve of each of said flanges facing each other; c. jacket means comprising a continuous sheet of inflatable material having a predetermined shape upon being inflated surrounding said hub and extending over the sleeves facing each other; d. an outer tire casing means enclosing said jacket means, forming a space therebetween, and extending over the cylindrical collar of each of the flanges for being expanded into the shape of said jacket means upon the jacket means being inflated; e. sealing means mounted on each said sleeve to prevent air from escaping from within said jacket means; f. means for clamping the ends of said tire casing means on each said collar; and g. means in one of said flanges for permitting gas under pressure to be injected into said jacket means for inflation thereof.
Claim 5
Dependent Claim
35 words
The wheel and tire assembly of claim 2 in which the width of said tire casing means to make contact with a riding surface is more than twice the diameter of said tire casing means.
Claim 6
Dependent Claim
23 words
The wheel and tire casing assembly of claim 3 having means to depressurize the space between said casing means and said jacket means.
