Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
114 words
An insulation support system for a furnace wall which comprises a plurality of panels arranged in side by side relation on the furnace wall, each panel including a metallic base member and metallic members having a flange attached in transversely spaced attached relation to and extending outwardly of the base member, and means including rods attached to the outwardly extending flanges and extending parallel to and spaced from the base of the panel for impaling and compressing a plurality of strips of heat insulating fibrous materials between flanges within each of the panels to provide a thickness of insulating fibrous materials between the interior of the furance and the metallic parts of the panels.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
17 words
An insulation support system according to claim 1 wherein the furnace wall consists of the furnace roof.
Claim 4
Dependent Claim
19 words
An insulation support system according to claim 2 wherein the furnace is a soaking pit with a removable roof.
Claim 5
Dependent Claim
45 words
