Insulating ceramic fiber batting module, anchoring system, ladle cover assembly and method of assembly
First Claim
1. A construction for heat insulating structure, comprising:
- frame means defining a volume to be filled with ceramic insulating batting material in an assembly to form the hot side of the structure and means defining the cold side of the structure;
ceramic insulating assemblies comprising a plurality of adjacent modules, each of which is formed from a unitary mat of ceramic batting, which mats are each of a predetermined width and length and a number of successive modules are formed by having such mat folded to have successive sections arranged as follows;
a first end section extending vertically at approximately a right angle to said cold side wall and surrounded by an adjacent vertical section of its mat on one side, by a third section at the end of said first section, and by a vertical fourth section, said second, third and fourth sections thus being folded into a generally U-shape cross section, with said first section sandwiched between said second and said fourth sections and received in the opening of the U, with a final section folded horizontally at an approximately right angle from said fourth section, said final section being adjacent said cold wall and extending a sufficient distance therealong so as to overlay the first, second and third sections of the next adjacent module in that direction; and
means for securing said modules to the means defining the cold side of said structure.

Abstract
A lightweight ladle cover employing ceramic fiber mats in modules. The modules are formed by having the generally rectilinear mat folded into five adjacent sections, the first of which depends vertically toward the "hot" side of the cover but is sandwiched between the second, third and fourth sections which form a vertical, horizontal ("hot" side) and vertical U-shape configuration about the first section. The last section is folded to extend horizontally to overlay part of the next module. The modules are anchored to an expanded metal wall at the "cold" side of the cover by an anchoring system which employs flat bars with spaced apart threaded studs welded to one flat side of the bar. In assembly, the studs are pierced through the mat at the junction of the first and second sections and then passed through openings in the expanded metal wall and secured by a washer and nut arrangement. The modules are then held by two bar-stud assemblies. The modules can be assembly by the process of laying down successive mats, securing them with anchoring asemblies, folding them in place and then repeating the process.

3. A cover for a ladle comprising:
a framework including a side assembly which encircles a volume at least partly filled with insulating material and which side assembly is sized and shaped to fit atop the ladle to be covered; an expanded metal wall spanning and secured to the top of said side assembly and covering said volume; a number of radial support members, each of which spans above said wall from the approximate center of the cover to at least generally opposite sides of the cover and each of which radial members extends beyond and beside said wall assembly and projects below the side assembly to form a leg, the legs of said number of radial members serve to straddle the ladle when the cover is placed on it;
each of said legs having a downward facing guide surface which projects below the side assembly and serves to align the cover on a ladle, each of said radial support member'"'"'s spanning and leg being formed of a unitary manner; andinsulating material in said volume which material includes a plurality of ceramic mats folded under and secured to said wall of said framework in modules, said plurality of mat modules covering the underside of said wall and filling the portion of the volume just below said wall. - View Dependent Claims (4, 5)
