Abstract
Abstract A tire curing chamber including a tank adapted to receive a multiplicity of tires in stacked relation in substantial axial alignment, opposed plates engageable with opposite ends of the stack, means mounting the plates in adjustable spaced relation to compress the tires in substantially airtight relation therebetween and to release the tires, one of said plates being ported to the atmosphere internally of the tires and the other being substantially fluid tight and with the tank defining a compartment externally of the tires, and a source of steam under pressure connected to said external compartment whereby when the external compartment is pressurized the plates are urged relatively toward each other, the adjustable mounting means having facility for limiting movement of the plates relatively toward each other incident to steam pressure in said external compartment.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
68 words
A tire curing chamber comprising a tank adapted to receive a plurality of tires therein in stacked relation: means for axially compressing the tires into substantially airtight engagement so as to form substantially isolated compartments in the tank, one thereof interiorly of the stacked tires and another exteriorly thereof; means for supplying steam under pressure to the exterior compartment; and means opening the interior compartment to the atmosphere.
Claim 2
Dependent Claim
68 words
A tire curing chamber comprising a tank adapted to receive a plurality of tires therein in stacked relation: means for axially compressing the tires into substantially airtight engagement so as to form substantially isolated compartments in the tank, one thereof interiorly of the stacked tires and another exteriorly thereof; means for supplying steam under pressure to the exterior compartment; and means opening the interior compartment to the atmosphere.
Claim 3
Dependent Claim
32 words
The chamber of claim 1 in which the compression means includes an impervious plate engaged with the stacked tires; and means for adjustably moving the plate axially toward and from the stack.
Claim 4
Dependent Claim
50 words
The chamber of claim 2 in which the exterior compartment extends across the plate externally thereof whereby the steam under pressure exerts an inward thrust on the plate axially of the stack; and the adjustable moving means limits movement of the plate toward the stack to resist excessive compression thereof.
Claim 5
Dependent Claim
58 words
The apparatus of claim 2 in which the adjustable moving means comprises a screw-threaded shaft mounted on the plate and axially extended away from the stack; a nut screw-threaded on the shaft; and means mounting the nut in spaced relation to the tank whereby rotation of the nut adjusts the shaft and plate toward and from the stack.
Claim 6
Dependent Claim
128 words
The apparatus of claim 2 in which the adjustable moving means comprises a tube mounted on the tank and extended therefrom axially of the stack having an outer end circumscribed by a flange; a screw-threaded shaft mounted on the plate and extended through the tube, a nut screw-threadedly mounted on the shaft for engagement with one side of the flange having fingers integral therewith extended about the peripheral edge of the flange for engagement with the opposite side thereof positively to limit movement of the nut toward and from the flange; and means for rotating the nut whereby the plate is movable, from and toward the stack to compress the tires but limits such movement of the plate towards the stack incident to steam pressure on the plate.
Claim 7
Dependent Claim
22 words
The apparatus of claim 1 including gaskets individually circumscribing the tires and extended between the tires to minimize leakage of steam therebetween.
Claim 8
Dependent Claim
119 words
A tire curing chamber comprising A. a substantially cylindrical tank having an opening to the atmosphere at one end and an opposite end having a releasably removable closure, said tank being adapted to receive tires in stacked relation therein in circumscribing relation to the opening; B. an airtight compression plate adapted to engage the stack of tires adjacent to the removable closure; C. means mounted on the closure connected to the plate operable to urge the plate toward the stack of tires to compress the same in the chamber into airtight engagement; and D. means for admitting steam to the chamber externally of the tires while the interior of the tires are open to the atmosphere through said opening.
Claim 9
Dependent Claim
119 words
A tire curing chamber comprising A. a substantially cylindrical tank having an opening to the atmosphere at one end and an opposite end having a releasably removable closure, said tank being adapted to receive tires in stacked relation therein in circumscribing relation to the opening; B. an airtight compression plate adapted to engage the stack of tires adjacent to the removable closure; C. means mounted on the closure connected to the plate operable to urge the plate toward the stack of tires to compress the same in the chamber into airtight engagement; and D. means for admitting steam to the chamber externally of the tires while the interior of the tires are open to the atmosphere through said opening.
