Abstract
Abstract Cell-shaped assemblies of firing setters for individually and spacably supporting a plurality of tiles and other ceramic ware during the firing of the glaze in a firing kiln comprise upright wall components made of refractory material with laterally extending projections for supporting the tiles. Further, transverse or horizontal components, also formed of ceramic material, with complementary configurations for interengaging transverse components in a co-planar manner, are provided and interlink the top and bottom ends of the upright components with the edge portions of the transverse components affording an essentially loose interfitting engagement of the components to provide an assembly made of a plurality of superimposed and sideby-side located cells.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
312 words
A firing setter assembly forming a three-dimensional structure for supporting tiles and other ceramic articles while they are being fired, comprising a plurality of similarly shaped first refractory ceramic components and a plurality of similarly shaped second refractory ceramic components, said first components arranged in at least two substantially vertically extending parallel planes, said second components arranged in at least two substantially horizontally extending parallel planes intersecting the upper and lower ends of said first components, said first components having first projections extending therefrom and said second components having bores for receiving said first projections in interlinking engagement, said second components having sides extending between said first components which are spaced apart in a horizontal direction and ends extending transversely of the sides with the ends of said second components shaped to interfit in interlinking engagement with one another, said first components forming wall members having vertically extending side surfaces with vertically spaced laterally extending second projections formed thereon for supporting the ceramic articles to be fired, the upper and lower ends of said first components forming bearing surfaces in contact with said second components extending between said first components, said first projections extending upwardly from the upper ends of said first components and downwardly from the lower ends of said first components, the bores in said second components arranged for receiving and acting as sockets for said first projections, said first projections extending upwardly from the upper ends of said first components are spaced laterally from the first projections extending downwardly from the lower ends of said first components and said first projections from said upper and lower ends are in an alternating arrangement, and the bores in said second components corresponding in number and shape with said first projections for receiving all said first projections on the upper and lower ends of said first components in a loosely interfitting manner.

Claim 3
Dependent Claim
59 words
A firing setter assembly, as set forth in claim 1, wherein said first projections having a dimension extending outwardly from said first components approximately equal to the thickness dimension of said second components and the bores in said second components extending completely therethrough so that said first projections extend through said second components for approximately the full thickness thereof.
Claim 4
Dependent Claim
156 words
A firing setter assembly, as set forth in claim 2, wherein each said second component is symmetrically formed about a center line extending between its ends, one end of said second component is wider than the other end and the sides of said second component converge from the wider end toward the narrower end, a cut-out formed in the wider end of said second component having a width slightly greater than the width of said narrower end and an end portion extending laterally from each side of said cut-out, the end portions of said wider end of said second component and the narrower end of said second component having bores formed therethrough so that when two second components are fitted together with the narrower end of one fitted into the cut-out in the wider end of the other, a line of bores extends across the connected ends with bores located in each of the interfitted ends.
