The object of-my presentv invention is` to provide improved apparatus for supporting tableware in kilns'of the type in which the products of combustion from the kiln heating system do not Contact withthe ware being' fired; further object of my inventionis to provide improved table ware supporting meanswhich Vare so constructed thatthe ware "to be fired can be placed in the ware supports and the supports placed Yon the car at aloading station and 'unloaded from `the car at a second station with a'lninimurnloss of ware and ware supports due to breakage. v

The "various features ofnovelty "which characterize my invention are pointed out with `particularityin theclaims annexed to and formingv 'aV part 4of' this/specification. For a better understanding of the invention, however, andthe advantages possessed' by it reference should behad to the accompanying drawings and descriptivematter in which I have'illustrated and described preferred Of thel drawings:

Fig. 3 is an elevation partly in section of a modification; f t Fig. 4 is a section on the line l-llof Fig. 3; Fig. 5 is an elevation partly in section of la second modification; V a

L Fig. 7 is a' plan view In the drawings andparticularly in Figs. 1 and 2 I have illustrated aVpreferred form of warersupport'in which the supporting frame orrack comprises a top frame A and a bottom vfranle B;V each of which is in the form of an open triangular frame having an enlarged boss CA at eachv corner thereof. Each boss is formed with a recess C for receiving one end of a pillar or post-D.

Inrthe preferred construction each post Y is formed with'afn'umbe'r of horizontally intlonli/` triangular ln cross-sectlon extending clined recesses vertically'spaced from one another. 1 Each recess has an enlarged porfcostly coring i ing the recesses in thepost. of a fourth modificaas ShOWnf inFis 1-u e formedat 'each' end ofuea'ch post and `corninwardly and apwaraly and ajamall passage E2 connecting the outerendof theportio'nEf to the outer face ofthe. post.kf As shown 'in' 'tion and madefof' refractorymaterial-,is
