KILN can. 7

' Application filed October 26,1926. Serial No. 144,203. 7

The general object of my present invention is to provide an improved construction of the superstructure of tunnel kilncars.

More specifically, the object of my present I) invention is to provide an improved method of converting a deck car of the'type in general use v in mufiie kilns into a type of car which can be used in direct fire kilns by constructing, the car superstructure in anim- 1 proved manner.

p The various features of novelty which characterize my invention are pointed out with particularity in the claims annexed to and forming a part of this specification. For a better understanding of the invention, however, its advantages andspecific objects attained with its use, reference should be 'had to the accompanying drawings and descriptive matter in which I have illustrated and described preferred embodiments of'my invention. a Y i Of the drawings:

Fig. 1 is a side view of the car superstructure partly in section; i

Fig. 2 is a plan viewv of my invention partly in section;

Fig. 3 is a plan view of one of the central flue tiles;

Fig. 4 is a wall tiles;

Fig. 5 is a plan view of one of the end wall tiles;

Fig. 6 is a plan view of one of the side posts; i

Fig. 7 is a plan view posts; and v Fig. 8 is a plan view of one of the bottom slabs. 1

In the drawings, A represents the body of a car suitable for moving ware through a tunnel kiln. The car is arranged with a superstructure adapted to support ware in position for heat treatment in a direct fired tunnel kiln. As shown, this superstructure consists of a lower platform composed of a plurality of slabs supported on piers, an upper platform composed of a plurality of slabs supported on a plurality of corner and plan View of one of the side ofone of the corner side posts and side and end wall tiles having their side portions fitting in slots in the corner and side posts to close the spaces between the posts. Hollow central tiles are provided to form up-draft fiuesthrough which the hot gases in the kiln chamber may pass upwardly from transverse passages between the piers so that the ware may receive substa ntially the same heat treatment on all sides.

In the particular construction illustrated, the car is provided with a series of trans verselyv extending pierlike members A which are separated from one another by lipse. In the construction shown, the platform is formedby eight of said slabs, each extending to the center line of the car and all of which are arranged to form two spaced elliptical openings, the major axes of which extend along the-longitudinal center line of the car. Two large hollow tiles C aremounted on the platform slabs with the inner wall of each tile in alignment with the edges of the corresponding elliptical platform opening. The tiles C taper slightly upwardly to anenlargedupper flanged edge portion C. Each tile C isprovided with a central transverse wall C extending vertically and serving as a reinforcement for the tile walls. I

At each corner of the rectangular platform composed of the slabs B is provided a post D in the form of a hollow vertical member'of general square cross section with the inner projecting corner beveled off as shown in Fig.2. Each of the inner sides of the post D is provided with a vertical slot D inclined at an angle to the ad acent outer side shown herein as substantially at a 30 angle and arranged to receive a the outwardly facing side. At the upper end ol each post IQ is termed a supporting flange portion 1 and a vertically pro ecting top portion I) of smaller cross-section.

The spaces between the various adjacent posts I) and I are tilled by side and end wall tiles l and (it. Each side wall tile 1* consists of a vertical central portion F and side portiiins F outwardly inclined at an angle of 3 l to the central portion F. The side portions are enlarged at their upper ends so that the outer face of the enlarged portion is in substantially the same vertical plane as the outer face of the central portion F. Each side wall tile F is vertically slidable in the inclined slots of the posts both when the upper platform is in positlon or l'Gll'lOVGtl. Each end wall tile G consists of a. vertical central portion G and side portions G inclined at a 30 angle to the central portion. The parallel top and bottom of each end tile piece are slightly inclined so that when mounted in position each end tile will be slightly inclined towards the outer side of the car. The side portions and (i are arranged to lit into the inclined slots in the side and corner posts I) and I to entirely surround the ware to be heat treated.

In the particular :form of the invention illustrated an upper platli'i'n'm composed of tour corner slabs II and two intermediate slabs .l is su niorted on the posts I) and I l and the hollow tiles C. Each slab H is llat and has one edge portion l-l shaped to lit a side wall tile F, the projecting top portions of theposts I) and E and the opposite edge I-l conforming with the inner face of the hollowccntral tile C. Each slab H is supported on the posts 1) and E, an end tile G and the flanged portion G oil one of the central tiles C. Each slab J has its outer edge J cut away to conform to the inner face of the side tiles I and the projecting top portion of the side posts E. Each slab J is supported in position by side posts I and the central tile flanges C.

The superstrncture may consist ot any number of similar decks arranged in the manner of the double decked structure shown in Fig. l of the drawings. If de sirablo some of the decks can be enclosed as described and others left partially or entirely open by removing the side or end wall tiles ll and G. The wall tiles and posts are ordinarily made of cast lire clay, although other materials capable of withstanding high temperatures could be used.

ll'ith the method of construction described, an open deck car such as ordinarily used in a tunnel kiln of the mullle type can be converted quickly and easily to a type of ware carrying car capable of being used in a tunnel kiln oi the direct tired type. In a kiln plant using both types of kilns,

an arrangement by which cars can be used in either type of kiln is very advantageous in reducing both the total apparatus and operating costs.

\Vhile in accordance with the provisions of the statutes, l have illustrated and doscribcd the best form otembodiment of my invention now known to me, it will be apparent: to those skilled in the art that changes may be made in the Form oi the apparatus disclosed without departing from the spirit of my invention as set .lorth in the appended claims and that in some cases certain features of my invention may be used to advantage without a corresponding use of other features.

Having now described my invention what I claim as new and desire to secure by Letters Patentis 7 1. In a kiln car, the combination of a supporting base having a transverse il'lne passage therein, with a ware supporting supeis -uct'ure having a hollow til serving as a vertical line mssage, said vertical passage being connected with said trai'isvcrse passage. n

:2. In a kiln car, the combination of a supporting base with a ware eup n'irting su pcrstructure comprising a lower platlorni having a line opening therein, an upper platform having a flue opening therein and rel'ractory means conncctingsaid lluc openings.

3. In a kiln car the combination of a supporting base with a ware sup jmrting superstructure con'iprising a lower platform having a line opening therein, vertical post members, an upper platform supported by said post members and having a line opening therein, and a hollow tile inen'iber connecting said flue openings.
