Abstract
Abstract A curing press for tires having relatively movable upper and lower mold sections, a center mechanism, a housing in the center mechanism, a hub attached to the housing, a bead ring carried by the hub for engaging the lower bead of a tire, a lift mechanism operatively engaging the housing for moving the hub relative to the lower mold section, and mold blow out apparatus on the hub for directing pressurized fluid into contact with the lower mold section during the movement of the hub relative to the lower mold section to remove residual foreign matter therefrom.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
97 words
In a tire curing press having upper and lower mold sections and a center mechanism having a bladder and including a vertically movable hub carrying a ring for engaging the lower bead of a tire, mold blow out apparatus comprising, tubular means mounted exteriorly of the bladder on the movable hub of the center mechanism, conduit means communicating with and supplying pressurized fluid to said tubular means, and a plurality of nozzle means on said tubular means for directing the pressurized fluid into contact with the lower mold section to effect removal of residual foreign matter therein.
Claim 2
Dependent Claim
97 words
In a tire curing press having upper and lower mold sections and a center mechanism having a bladder and including a vertically movable hub carrying a ring for engaging the lower bead of a tire, mold blow out apparatus comprising, tubular means mounted exteriorly of the bladder on the movable hub of the center mechanism, conduit means communicating with and supplying pressurized fluid to said tubular means, and a plurality of nozzle means on said tubular means for directing the pressurized fluid into contact with the lower mold section to effect removal of residual foreign matter therein.
Claim 3
Dependent Claim
34 words
Apparatus according to claim 1, wherein said nozzle means are oriented downwardly to direct the pressurized fluid into contact with the lower mold section during vertical movement of the hub of the center mechanism.
Claim 4
Dependent Claim
34 words
Apparatus according to claim 2, wherein the impingement of the pressurized fluid on the lower mold section varies radially thereof as a function of the vertical movement of the hub of the center mechanism.
Claim 5
Dependent Claim
22 words
Apparatus according to claim 2, wherein said nozzle means are directed downwardly from a horizontal plane at an angle of approximately 45°.
Claim 6
Dependent Claim
24 words
Apparatus according to claim 1, wherein said tubular means is substantially circular and disposed about the periphery of the hub of the center mechanism.
Claim 7
Dependent Claim
23 words
Apparatus according to claim 5 wherein said nozzle means is a plurality of cylindrical members generally equally circumferentially spaced about said tubular means.
Claim 8
Dependent Claim
40 words
Apparatus according to claim 5, wherein said nozzle means are angularly offset from a direction radially of said tubular means and the hub such as to produce a circumferential swirling action of the pressurized fluid about the lower mold section.
Claim 9
Dependent Claim
38 words
Apparatus according to claim 7, wherein the axis of each of said nozzle means is displaced outwardly of a tangent to said tubular means at its intersection with each said nozzle means at an angle of approximately 30°.
Claim 10
Dependent Claim
33 words
Apparatus according to claim 1, including means for providing cyclic supply of pressurized fluid through said conduit means to said tubular means over a portion of the travel of the vertically movable hub.
Claim 11
Dependent Claim
104 words
A curing press for tires having relatively movable upper and lower mold sections comprising, a center mechanism, housing means in said center mechanism, hub means attached to said housing means, bead ring means for engaging the lower bead of a tire carried by said hub means, lift mechanism means operatively engaging said housing means for moving said hub means relative to the lower mold section, and mold blow out means on said hub means for directing pressurized fluid into contact with the lower mold section during the movement of said hub means relative to the lower mold section to remove residual foreign matter therefrom.
Claim 12
Dependent Claim
104 words
A curing press for tires having relatively movable upper and lower mold sections comprising, a center mechanism, housing means in said center mechanism, hub means attached to said housing means, bead ring means for engaging the lower bead of a tire carried by said hub means, lift mechanism means operatively engaging said housing means for moving said hub means relative to the lower mold section, and mold blow out means on said hub means for directing pressurized fluid into contact with the lower mold section during the movement of said hub means relative to the lower mold section to remove residual foreign matter therefrom.
Claim 13
Dependent Claim
36 words
Apparatus according to claim 10, including control means providing a supply of pressurized fluid to said mold blow out means during a portion of the movement of said hub means relative to the lower mold section.
Claim 14
Dependent Claim
20 words
Apparatus according to claim 11 wherein said control means includes cam means operating in conjunction with said lift mechanism means.
Claim 15
Dependent Claim
40 words
Apparatus according to claim 10 wherein said bead ring means engages the lower bead of a tire so that the movement of said bead ring means effected by said lift mechanism means separates a tire from the lower mold section.
Claim 16
Dependent Claim
32 words
Apparatus according to claim 10 wherein said mold blow out means includes tubular means circumposed about said hub means and a plurality of nozzles directing the pressurized fluid from said tubular means.
