Abstract:
The invention herein teaches a crown system for kilns and furnaces for the high temperature firing of materials. One method used in the industry for a crown system consists of supporting layers of insulation with inverted T-rails attached to bones which are further attached to hanger devices hanging from pipes that rest upon an ultimate support system. To overcome the numerous problems associated with the prior art the following considerable modifications have been made: 1) slotting each inverted T-rail, along its narrow attaching flange and adding stops to each side of said slot such that the bone is evenly spaced along the T-rail when inserted and slid into position, 2) fitting rigid insulation cases fully between the bones and adjacent layers of insulation and 3) said insulation cases and said T-rail stops combine to lock said bones in position. Further improvements to this system include: 1) widening the T-rail's broad base width, 2) angling the ends of the T-rail, 3) increasing the bone's stem length, 4) placing stops on the ultimate support system to hold the pipes in place, 5) a thermal tent which envelopes the bone's upper attaching end and 6) shaping the attachment hole on the bone as a curved cylinder.

Abstract:
A suspended crown of an industrial furnace formed of anchored refractory bricks, additional refractory bricks, and refractory plates. The anchored bricks are formed at one end with means for engaging hooks which secure the bricks to support beams, and at their opposite ends with shoulders for carrying the refractory plates. The sides of the anchored and additional bricks are formed with teeth which mesh with teeth in adjacent bricks. The plates are generally rectangular and provided with parallel channels for reducing their weight.
