Abstract
Abstract A prefabricated insulating structure is formed from a ceramic fiber blanket, folded into plural folds, for insulating a corner formed by two walls within a furnace. The folded blanket is mounted in a curved configuration to a single attachment mounting such that each of the two ends of the curved folded blanket is adjacent one of the walls at the corner. The folded blanket is mounted to the attachment mounting by two support members, each of the support members being mounted in a fold adjacent one of the ends of the folded blanket.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
131 words
An insulating structure for insulating a corner between two walls in a furnace, comprising: a. a folded insulating blanket of fiber insulating material, said folded blanket including: 1. a curved inner surface portion exposed to the interior of the furnace; 2. a first side surface portion extending from said curved inner surface portion to a fold formed in said blanket for placement adjacent a first one of the two furnace walls at the corner; 3. a second side surface portion extending from an opposite end of said curved inner surface portion from said first side surface portion to a fold formed in said blanket for placement adjacent the second of two furnace walls at the corner; and b. means for attaching said insulating blanket to the furnace walls at the corner.
Claim 2
Dependent Claim
131 words
An insulating structure for insulating a corner between two walls in a furnace, comprising: a. a folded insulating blanket of fiber insulating material, said folded blanket including: 1. a curved inner surface portion exposed to the interior of the furnace; 2. a first side surface portion extending from said curved inner surface portion to a fold formed in said blanket for placement adjacent a first one of the two furnace walls at the corner; 3. a second side surface portion extending from an opposite end of said curved inner surface portion from said first side surface portion to a fold formed in said blanket for placement adjacent the second of two furnace walls at the corner; and b. means for attaching said insulating blanket to the furnace walls at the corner.
Claim 3
Dependent Claim
45 words
The insulating structure of claim 1, wherein: a portion of said fibers in said layers of said blanket adjacent said folds being transversely disposed to the remainder of said fibers and extending into other adjacent layers to bind the layers together into an insulating structure.
Claim 4
Dependent Claim
81 words
The structure of claim 1, wherein said means for attaching comprises: a. a support member mounted in said fold formed adjacent the first one of the two furnace walls; b. a suspension arm having said support member mounted therewith, said suspension arm having mounting means therewith extending through said insulating blanket; and c. a mounting member receiving said mounting means of said suspension arm, said mounting member further being adapted for attachment to the first one of the two furnace walls.
Claim 5
Dependent Claim
62 words
The structure of claim 3, wherein said means for attaching further comprises: a. a second support member mounted in said fold formed adjacent the second of the two furnace walls; and b. a second suspension arm having said second support member mounted therewith, said second suspension arm having mounting means therewith extending through said insulating blanket and mounted with said mounting member.
Claim 6
Dependent Claim
75 words
The structure of claim 4, wherein said mounting member comprises: a mounting member having a first side member thereof formed at an angle to a second side member conforming to the angle of intersection of the furnace walls at the corner being insulated, said mounting member receiving said mounting means of said first suspension arm in said first side member and receiving said mounting means of said second attachment arm in said second side member.
Claim 7
Dependent Claim
56 words
The structure of claim 5, wherein: the two furnace walls form an outwardly exposed corner and said first side member is attached to the first wall and said second side member is attached to the second wall whereby said insulating structure is mounted about the corner for insulating the corner from the interior of the furnace.
Claim 8
Dependent Claim
34 words
The insulating structure of claim 1, wherein said folded blanket further comprises: inner side surface portions mounted inside said side surface portions extending inwardly from each of said folds formed in said surface portions.
Claim 9
Dependent Claim
31 words
The insulating structure of claim 1, wherein said folded blanket further comprises: an inner insulating fold extending along the interior surface of said curved inner surface portion opposite said thermal surface.
Claim 10
Dependent Claim
32 words
The insulating structure of claim 1, wherein an enclosure is formed adjacent said thermal surface of said inner wall member portion and further including: an insulating core member mounted within said enclosure.
Claim 11
Dependent Claim
21 words
The insulating structure of claim 9, wherein: said insulating core member substantially fills the enclosure formed by said folded insulating blanket.
Claim 12
Dependent Claim
50 words
The insulating structure of claim 9, wherein said insulating core member comprises: a core member of insulating fibers having a portion of said fibers transversely disposed to the remainder of said fibers and extending into said inner wall portions of said blanket to mount said core member with said blanket.
Claim 13
Dependent Claim
18 words
The insulating structure of claim 11, wherein said insulating core material comprises: a core of solid insulating material.
