Abstract
Abstract A self-sealing valve for an inflatable object such as a vehicle tire or tube in which the valve is comprised of an aperture through the wall of the casing of the tire or tube and includes a thin flexible and deformable piece of material sealed to the inner wall of the casing or tube and having an aperture therein offset from the aperture in the casing or tube which will be displaced upon entrance of a hollow tube through the apertures in the casing and thin piece of material to allow entrance of air into the casing. The pressure of the inflating air or medium introduced through the hollow tubular member will cause the thin flexible and deformable piece of material to conform to the inner wall of the casing to seal the aperture therethrough.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
229 words
The combination of a self-sealing valve and an inflatable object comprising, a hollow inflatable object having a predetermined wall thickness with at least a portion of said wall being made of a deformable and expandable material, an aperture positioned through the wall of the object, a thin flexible piece of elastic and deformable material sealed to the wall of the object about the aperture therein and having a thickness dimension substantially less than the wall thickness of the object surrounding the aperture, said thin flexible piece of elastic material having an aperture in the wall of the object, said apertures in the walls of the object and in the thin elastic deformable material having substantially the same diametrical dimensions and being offset such that the axes of the apertures are spaced apart a distance slightly greater than the diametrical dimension of said apertures, but less than twice the diametrical dimension of the apertures, and a hollow tubular member adapted to be inserted through the aperture in the wall of the object and the aperture in the think elastic material sealed to the inner wall of the object by deforming the thin elastic material, the pressure of the inflating medium introduced through the hollow tubular member into the inflatable object causing the thin flexible elastic material to conform to the inner wall of the object to seal the aperture therethrough.
Claim 2
Dependent Claim
229 words
The combination of a self-sealing valve and an inflatable object comprising, a hollow inflatable object having a predetermined wall thickness with at least a portion of said wall being made of a deformable and expandable material, an aperture positioned through the wall of the object, a thin flexible piece of elastic and deformable material sealed to the wall of the object about the aperture therein and having a thickness dimension substantially less than the wall thickness of the object surrounding the aperture, said thin flexible piece of elastic material having an aperture in the wall of the object, said apertures in the walls of the object and in the thin elastic deformable material having substantially the same diametrical dimensions and being offset such that the axes of the apertures are spaced apart a distance slightly greater than the diametrical dimension of said apertures, but less than twice the diametrical dimension of the apertures, and a hollow tubular member adapted to be inserted through the aperture in the wall of the object and the aperture in the think elastic material sealed to the inner wall of the object by deforming the thin elastic material, the pressure of the inflating medium introduced through the hollow tubular member into the inflatable object causing the thin flexible elastic material to conform to the inner wall of the object to seal the aperture therethrough.
Claim 3
Dependent Claim
21 words
The combination of the self-sealing valve and inflatable object of claim 1 in which the inflatable object is a tire casing.
Claim 4
Dependent Claim
34 words
The combination of the self-sealing valve and inflatable object of claim 2 in which the aperture positioned in the wall of the object is positioned in the sidewall of the casing of the tire.
Claim 5
Dependent Claim
32 words
The combination of the self-sealing valve and inflatable object of claim 2 in which the aperture in the wall of the tire casing is positioned in the crown portion of the casing.
Claim 6
Dependent Claim
56 words
The combination of the self-sealing valve and inflatable object of claim 1 in which the thin flexible piece of elastic and deformable material includes a plurality of layers of materials sealed at their peripheral edges with offset apertures in each layer and with the layer contacting the inner wall of the inflatable object being sealed thereto.
Claim 7
Dependent Claim
71 words
The combination of the self-sealing valve and inflatable object of claim 5 in which the plurality of layers of elastic and deformable material include at least three layers and in which said layers of said plurality of layers in nonadjacent relationship have apertures therein which are aligned and with at least one of the apertures in the plurality of layers being aligned with the aperture in the wall of the object.
Claim 8
Dependent Claim
157 words
A self-sealing valve for a tire casing comprising, a tire casing including a mounting for the same, an aperture positioned in the tire casing and eXtending from the exterior surface to the interior surface of the same and positioned remote from the support for the casing, and at least one disc of a thin flexible elastic deformable material positioned on the interior surface of the casing and sealed thereto over the aperture in the wall of the casing, said thin flexible elastic disc having an aperture therein positioned in adjacent and nonoverlapping relationship with the aperture in the wall of the casing, said apertures in the wall through the casing and in the thin elastic deformable disc have substantially the same diametrical dimension and are offset such that the axes of said apertures are spaced at a distance slightly greater than the diametrical dimension of said apertures but less than twice the diametrical dimension of the apertures.
Claim 9
Dependent Claim
157 words
A self-sealing valve for a tire casing comprising, a tire casing including a mounting for the same, an aperture positioned in the tire casing and eXtending from the exterior surface to the interior surface of the same and positioned remote from the support for the casing, and at least one disc of a thin flexible elastic deformable material positioned on the interior surface of the casing and sealed thereto over the aperture in the wall of the casing, said thin flexible elastic disc having an aperture therein positioned in adjacent and nonoverlapping relationship with the aperture in the wall of the casing, said apertures in the wall through the casing and in the thin elastic deformable disc have substantially the same diametrical dimension and are offset such that the axes of said apertures are spaced at a distance slightly greater than the diametrical dimension of said apertures but less than twice the diametrical dimension of the apertures.
Claim 10
Dependent Claim
55 words
The self-sealing valve of claim 7 in which the thin flexible disc of an elastic and deformable material includes a plurality of layers of material each with a separate aperture therethrough and with the apertures in said layers being offset a distance no greater than a spacing of twice the diametrical dimension of the apertures.
Claim 11
Dependent Claim
79 words
A self-sealing valve for an inflatable object comprising, a disc formed of a plurality of layers of a thin flexible elastic and deformable material in which the layers are sealed at the circumferential edge of the same and in which each layer has an aperture therethrough substantially the same diametrical dimension with the apertures in adjacent layers being offset from one another to be in nonoverlapping relationship and with apertures in noncontacting layers being disposed along the same axis.
Claim 12
Dependent Claim
79 words
A self-sealing valve for an inflatable object comprising, a disc formed of a plurality of layers of a thin flexible elastic and deformable material in which the layers are sealed at the circumferential edge of the same and in which each layer has an aperture therethrough substantially the same diametrical dimension with the apertures in adjacent layers being offset from one another to be in nonoverlapping relationship and with apertures in noncontacting layers being disposed along the same axis.
