wARE SUPPOR Filed Feb.l 21, 1930 A A A A A A A A A A AA varied in accordance with the size of the pieces to be fired and the operating conditions present. I have for example, for firing 41/2" square tile constructed a tile setter with approximately a depth of lflf, an uppr and lower flange Width of 91/2" and a length. of 13, the web containing twelve horizontal rows of pin openings Vertically spaced 1%" between centers. The pin openings and pins may be of various cross-sectional forms,a triangular or square form, however, being particularly advantageous due to the knife edge contact obtainable between the pins and ware pieces. The pins may be easily removed and renewed or replaced with another knife edge in the contacting position.

It will be noted that the main supporting member A is a unitary self-supporting member in stable equilibrium both When the support is loaded and unloaded and requires no auxiliary members'to maintain it in position. The upper flange present in the I-beam type is advantageous in providing means for protecting the ware surfaces from sand or other dbris dropping from above and in providing a supporting base for superposed supports and means by which the Ware supports can be easily handled during the car loading and unloading operations.

The Weight of the supports is relatively small, permitting the supports to be loaded by female labor at Work benches. The construction permits rapid loading and unloading operations, particularly with tile pieces, which can be quickly removed from the support by shaking.

The ware supports of my invention are especially adapted for various arrangements longitudinally or transversely of the kiln car.V A preferred arrangement is illustrated in Fig. 1 by Which the tiles normally in the portion of the car receiving underheating receive the proper amount of heat, while the tiles in another portion normally exposed to excessive temperatures are partly potected. As shown in Fig. 1, a kiln car Which is of a type well understood in the art, is loaded with a plurality of rows of ware supports LA with their webs extending transversely of the lower portion of the car with the adjacent supports in each row in substantially end to end contact and the adjacent supports in adjacent rows having thelr upper and lower flange edges substantlally ln contact. A second tiel' of supports LA may be 'positioned on the vupper flanges of the lowerrow, as shown.` This transverse arrarlgement vof the supports vin the lower portion of the car forms transverse channels for the circulating kiln atmosphere, therebyincreasing the heat transfer to the tiles.

`Mounted on the uppermost transverse tier are one or more tiers of supports HA,

the supports HA in each tier being arranged longitudinally of the car with the adjacent supports in each row in end to end contact, thus diminishing the transverse circulation of the kiln atmosphere in that portion of the car and thereby reducing the usually excessive heating of the tiles therein.

In Fig. ll I have illustrated a modified .form of sup Dort having the described arrangement o upper and lower flange members A' and A3, respectively, and a central Web A2. In lieu of the Web openings and supporting pins, I have provided a series of Vertically spaced horizontally projecting shelves F, Which extend longitudinally of and are integrally connected to the Web A3.

The Ware support of Fig. 4 is preferably manufactured by an' eXtrusion process in which a supply of plastic refactory material is forced through a die of the proper shape by an eXtrusion machine toV produce a one-piece rectangular tube having Vertical side Walls A5 as indicated by broken lines in Fig. 4, and a plurality of internal shelves and a Vertical Web extending between and integrally connected to the tube Walls. After a dcsired amount of lnaterial has been eXtruded, the Vertical side Walls A5 of the extruded article are cut away from the shelves and flanges, leaving a Ware support of the form indicated in full lines in Fig. 4. The eXtruded article is subjected to the necessary iring operations and the support is then ready for use.

While in accordance With the provisions of the statutes, I have illustrated and described the best forms of embodiment of my invention now known to me, it will be apparent to those skilled in the art that changes may be made inv the form of the de- Vice-and of the methocl of manufacture disclosed Without departing from the Spirit of my invention as set forth in the appended claims and that in some cases certain fea;

tures of my invention may be used to ad- Vantage Without a corresponding use of other features.

Having now described my invention what I claim as new and desire to secure by Let-1. ters Patent, is:

1. A support for ceramic Ware conlprising an elongated main supporting` member having a base flange and a Vertical web, and a plurality of horizontally extending warel supporting members extendng laterally from said web.

2. A support for ceramic ware comprising an elongated main su porting member of a substantially'standar. structural shape including a horizontal base flange and a Vertical web, and laterally projecting mem- 'bers carred by said web for supporting Ware ieces.

3. support for ceramlc ware comprising an elongated main Supporting member having' a substantially standard I-beam t cross-section, and a plurality of ware su ,porting pins mounted in the web of sald main supporting member and projecting horizontally at each Side thereof.

4. A tile setter comprising an elongated main supporting member having horizontally extending top and bottom anges and a central Web extending vertically between and integrally formed with said flanges, a plurality Of horizontal rows of openings formed in said web, and a pin mounted in each of said openings arranged to project a predetermined distance from each side of said web, wherebyl a plurality of tile pieces are adapted to be supported on said pins at each side of said web.

5. In a kiln car, a plurality of rows off Ware supports, each having a Vertical web arl ranged transversely of the lower portion of` the car to form a series of transverse channels, and a plurality of rows of similar ware supportsmounted on said first mentioned rowsl and each having. its Vertical web ex-V tendng longitudinally of the car, whereby the transverse Vcirculation' of the kiln atmosphere is increased in theV lower portion and decreased in the uppver portion of the 6. A support for ceramic ware comprising an elongated main supporting member having a substantially standard I-beam crosssection, and a plurality of ware supporting shelf members integrally connected to the web of said main supportin member and projecting horzontally at eac side thereof.

Signed at New Castle, in the county of Lawrence and State of Pennsylvania, this 13 day of February, A. D. 1930.
