The invention relates to racks for supporting plates, dishes and similar porcelain or china ware and the like in a Saggan'for burning or baking in a kiln. The saggar is a box or case of hard clay or the like, usually made so the bottom of one forms the cover ofthe next, thus protecting the articles within from smoke, and the irregularities of heat and the like. I 10 It isusual practicein burning plates and similar articles to place the same on theedge within the saggar, the lower edges of the I plates resting upon spaced triangular-bars loosely positioned uponythe bottom of the 5 saggar. a I 5 The weight of the plates resting on these separate bars often causes the bars to move laterally, permitting a portion of the edge. of the plate to contact with the bottom of the saggar, and'sineeit is customary to placea layer of sand on the bottom of the saggar, the

edges of the green platesfrequently contact with this sand causing the same to be burned into the plate and ruining the same.

I The object of the present invention is to I provide a'rack arranged tobe placed upon the sand in the bottom of the saggar to support the plates in theordinary position, this rack being 'so' arr'angedand constructed that it is i with the sand.

impossible for the edge of the plate to contact The above and other objects may be. at-.

.tained by providing a rack of such size and shape that the edge portion of each plate will have only one or two point contacts with the rack; the lowerside of the rack being pro vided with one or more ribs arranged tobe imbedded in the sand upon the bottom of the.

saggar to prevent lateral movement of the rack within the saggar. I I

An embodim-entof the invention thus set.

forth is illustrated "in; the accompanying drawing, in which i I Figure 1 is a fragmentary longitudinal sectional' view through a portion of a saggar, showing the i'mprovedburning rack inposition to support a row of plates; T :Fig. 2, a transverse'sectionalview through the same; I I I Fig.3, a fragmentaryperspective view of a portion of the improved burning rack,.and. I Fig. 4, a similar View of a different form of the rack. I I I I :Sirpilar numerals of'reference indicate cor I responding parts throughout the :drawing.

Thesaggar 1 maybe of any usual and well lz'nowniiconstruction, being in the-for-m-ofa I box arrangedto befclosed at its top by placing anothersag'gar thereon as illustrated infFigs. I v

l and 2. m p 1 A layer-of sand, as indicated at 2, is placed upon the bottom of each saggar,and theimproved burningracks areplaced uponvsaid I layer of sand at properlyspaced intervals within-the saggar from one end tothe other.

I These burning racksmay be formed of clay, .or other suitable material, and as r shownin fFigs. 2. and 3,"may .be' of substantially channel @concaveas shown .at 5,-thus providing two spaeed ribs-fi, adapted to be imbedded in the grates 01 the like, as indicated a 7, are so then placed- ,in r.oyvs upon each burning rack,

:the loweriedges-oftheplates restingat spaced points on the edges ofthe triangular ribse'a,

,.;and i the upper portions of the plates resting up'on thetriangular-pins 8,.ithe-plates being entirelyns'upportedabovethebottom of the I sa gar and out of contact with the sand.

ince the triangular ribs 4 are formed invtegrally upon the rack it, will be seen that I there can be no relative movement or" these a {IlbS to permit the platesto be displaced; and

by providing the lower ribs 6. upon the rack the same may be imbedded in the sand and --will prevent any lateral displacement of the rack due to the weight of the platesresting thereon. I

j' I As shown in Fi 4,-the rack 3, may have thesingle triangular rib Pupon its upper isurface, providing for a one point contact H withrthe plate or other article to-be burned,

F T f" I the rack being otherwise the same as above described.

I claim:

1. In combination, a saggar, a layer of sand upon the bottom of the saggar, and a burning rack for said saggar upon the sand, means extending upward from and integral with the rack spacing the edge of a plate supported thereon entirely above the bottom a of the saggar and out of contact with the sand, and means extending downward from the rack imbedded in the sand preventing lateral displacement of the rack in the sand.

2. In combination, a saggar, a layer-of sand upon the bottom of the saggar, and a burning rack for said saggar upon the sand, the burning'rack including a body portion, an upright rib integral with the body portion spacing the edge of a plate supported 7 thereon entirely above the bottom ofthe saggar and out of contact with the sand, and means extendingdownward' from the body portion imbedded in the sand preventing lateral displacement of the rack in the sand.

3. In combination, a saggar, a layer of sand upon the bottom of the saggar, and a burning rack for said saggar upon the sand, the burning rack including a body portion, an upright rib integral with the body portion at each longitudinal edge of the body portion spacing the edge of'a plate supported thereon entirely above the bottomof the saggar and out of contact with the sand, and means extending downward from the rack imbedded in the sand preventing lateral displacement of the rack in the sand.

4:. In combination, a saggar, a layer of sand upon the bottom of the saggar, and a burning rack for said saggar upon the sand, the burning rack including a body portion, a triangular rib extending upward from and integral with the body portion spacing the edge of a plate supported thereon entirely above the bottom of the saggar and out of contact with the sand, and means extending downward from the body portion imbedded in the sand preventing lateral displacement of the rack in the sand. Y

, In testimony that I claim the above,"I have hereunto subscribed my name.
