Abstract
Abstract A refractory setter device for supporting glazed ceramic ware incident its firing within a kiln comprises an open spider having an upwardly facing surface above which the ware article is to be supported with such surface having a plurality of conical pockets arranged in at least three radial locations relative to the center of the spider and a spherical ball engaged within the conical pocket at such three radial locations, such that the ceramic ware article when supported on the setter device has three point contact engagement with the spherical balls.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
130 words
A refractory setter device for supporting glazed ceramic ware within a firing kiln comprising: an open spider providing an upwardly facing surface above which a ceramic ware article is to be supported within the firing kiln; a plurality of conical pockets opening outwardly of and disposed within said upwardly facing surface, at least one said conical pocket being disposed in each of three radial locations relative to the center of said spider; and a spherical ball engaged within one said conical pocket at each of said three radial locations whereby a ceramic ware article when supported on said setter device has three point contact engagement with said spherical balls, each said ball having the exterior thereof in limited line contact with the conical pocket within which the ball is engaged.
Claim 2
Dependent Claim
130 words
A refractory setter device for supporting glazed ceramic ware within a firing kiln comprising: an open spider providing an upwardly facing surface above which a ceramic ware article is to be supported within the firing kiln; a plurality of conical pockets opening outwardly of and disposed within said upwardly facing surface, at least one said conical pocket being disposed in each of three radial locations relative to the center of said spider; and a spherical ball engaged within one said conical pocket at each of said three radial locations whereby a ceramic ware article when supported on said setter device has three point contact engagement with said spherical balls, each said ball having the exterior thereof in limited line contact with the conical pocket within which the ball is engaged.
Claim 3
Dependent Claim
65 words
A refractory setter device as recited in claim 1 wherein said spider has at least three arms extending radially from a central portion of said spider, and each of said arms has means adjacent the radially outer end thereof to accommodate stacking a plurality of said spiders on top of each other while maintaining adjacent spiders spaced sufficiently to support a ceramic ware article therebetween.
Claim 4
Dependent Claim
50 words
A refractory setter device as recited in either of claims 1 or 2 wherein each said conical pocket has the cone base thereof disposed in the plane of said upwardly facing surface, and said base has a diameter less than the diameter of said spherical ball that is engaged therewith.
Claim 5
Dependent Claim
47 words
A refractory setter device as recited in claim 3 wherein said cone base is of a diameter sufficiently less than the diameter of said spherical ball such that the ball exterior engages with the perimeter of the base of the conical pocket within which it is received.
Claim 6
Dependent Claim
42 words
A refractory setter device as recited in either of claims 1 or 2 wherein said upwardly facing surface has a series of said conical pockets spaced along each of at least three radial lines that intersect at the center of said spider.
