Application filed May 17, 1906. Serial No. 260,833.

To aZZ whom it may concern.-

Be it known that I, JULIUS C. HINZ, a citizen of the United States, residing at Detroit, in the county of Wayne, State of Michigan, have invented certain new and useful Improvements in China-Kilns and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to china-kilns for firing decorated china; and it consists in the construction and arrangement of parts hereinafter fully set forth, and pointed out particul arly in the claims.

The object of the invention is to provide a portable china-kiln of simple, durable, and inexpensive construction wherein the arrangement is such as to protect the oven from the products of combustion and at the same time provide for a circulation of the caloric current around the oven in a manner to thoroughly and evenly heat it, whereby the firing of china and other materials may be evenly and perfectly accomplished. A further arran ement provides for the forming of the walls of the oven of hollow tiles having transverse partitions which afford fines for the passage of the caloric current and for the forming of hollow sills upon which the blocks of tiling rest and through which the heat from the burner is directed, it being desi ned to use hydrocarbon fuel in heating the Iiiln. The above object is attained by the construction and association of parts illustrated in the accompanying drawings, in which Figure 1 is an elevation of the kiln embodying my invention. Fig. 2 is a central vertical section therethrough, as on line 2 2 of Fig. 1. Fig. 3 is a plan view of the kiln, showing by dotted lines the location of the flues in the wall of the oven and their communication with the fluepipe. Fig. 4 is a horizontal section as on line 4 4 of Fig. 1. Fig. 5 is a vertical transverse section through the kiln at right angles to the section shown in Fig. 2. Fig. 6 is a plan view of a section or block of the two-p art tiling employed at the rear wall of the oven. Fig. 7 is a like view of one of the corner-sections. Fig. 8 is a similar view of one of the side sections. Fig. 9 is a plan view of one of the front corner-sections. Fig. 10 is a perspective view of one of the hollow base-sections or sills. Fig. 11 is a fragmentary view, in horizontal section, showing the connection of one of the upper sections of tiling with a sill or base-section. Fig. 12 is a perspective view of one of the corner basesections.

Referring to the characters of reference, 1

designates a sheet-iron casing forming the exterior of the kiln and mounted upon supporting-legs 2. Within the sheet-iron casing is a heavy lining of asbestos 3, and within the asbestos and surrounded thereby is the hollow wall 4 of tiling. The burner 5 is of any suitable hydrocarbon type and is supported below the bottom 6 of the kiln, the fuel being supplied thereto throu h the pipe 7. Within the base of the kiln am? supported by the bottom thereof are the hollow sills formed of blocks or sections of tiling comprising the quadrangular end and side sections 8 and the L-shape corner-sections 9. These sill-sections surround the combustion-chamber 10, located centrally within the base of the kiln and with which the burner 5 communicates. The top of the combustion-chamber is formed by the fire-clay bottom 11 of the oven, which is supported upon the ledge 12, afforded by the sill-pieces. As before stated, the sillpieces of tiling are hollow and are provided with openings 13 in their inner faces, which communicate with the combustion-chamber, and with openings 14 in their upper faces, which communicate with the openings through the hollow divided tiles, forming the walls of the oven. Upon one end of each of the sill-sections of tiling is a projection 15, and formed in the opposite end of each of said sections is a recess 16, adapted to receive the projection on the succeeding sill-section. By this arrangement the sills are made to interlock and are firmly held in position when placed together. Surrounding the central openings 14 through the tops of the sill-sections is a raised flange 17.

The tile-sections which form the walls of the oven are made in two parts, the sections forming the ends and sides of the oven con sisting of an inner part 18, having the transverse partitions 19 and the ends 20 and of an outer or backpart comprising a straight slab 21, adapted when placed a ainst the inner part 18 to form a complete hollow tile with transverse partitions, producing the vertical flues 22, extending therethrough. The corner sections or blocks of tiling comprise the L-shaped inner part 23, carrying the trans- IIO versely-extending partitions 24, and the outer L-shape part 25, adapted to lie against the projecting ends of said partitions to form the complete tile-section, having the vertical 5 fiues 26. The lower ends of the blocks or sections of tiling formed by the inner and outer pieces, as described, are recessed around the inner margins thereof to receive the raised flange 17 on the sill-sections, whereby I said parts are locked together and the escape of the products of combustion into the oven is obviated. It will be noted that the end pieces 20 of the straight sections of tiling proj ect slightly and that the back pieces thereof I have projecting tenons 27. It will also be noted that the ends of the corner-section are recessed, as at 28, to receive the projecting ends and 27 of the interposed sections, an arrangement which securely ties the sections 20 of tilin together and affords a solid and substantia wall for the oven, through which the gases from the combustion of the fuel cannot pass.

Fitted upon and supported by the upper ends of the hollow sections of tiling forming the wall of the oven are the hollow tiling-sections 29, which serve as the top of the oven and are provided with the horizontal flueopenings 30, which communicate with the 30 vertical flue-openings 22. Formed through the upper walls of the tile-sections 29 are apertures 31, through which the caloric current passes into the upper chamber 32 above the oven, with which the branches 33 of the 5 flue-pipe 34 communicate. By this arrangement the heat from the burner is presented on the bottom, sides, and top of the oven in a manner to uniformly and intensely heat the interior thereof, the passages for the caloric 0 current being within the sections of tiling of which the oven is constructed, forming a simple and inexpensive yet durable kiln.

The door 35 of the oven is formed in the usual way and is made taperin to tightly it the opening, so as to prevent the escape of eat.

Having thus fully set forth my invention, what-I claim as new, and desire to secure by Letters Patent, is

1. In a portable china-kiln, the combination of an exterior casing, having a combustion-chamber in the base thereof, hollow sillsections surrounding said chamber and communicating therewith, each of said sill-sections having a horizontal supporting-surface, the supporting-surfaces of said sill-sections, when said sections are placed together, forming a continuous ledge at the base of the oven, the oven-bottom supported upon said ledge and forming the top of the combustion-cham- 6o municating with the interior of the hollow tile-sections, forming the top of the oven.

2. In a china-kiln, the combination with the exterior casing, a plurality of hollow sills located in the base of the casing surrounding a central space forming a combustion-chamber, the sides of the oven of the kiln being formed of separable tile-sections, comprising an inner part having transverse partitions, and an outer part closin against said partitions to complete the ti e-section and form vertical fiues therethrough, said tile-sections having interlocking members which unite them in the wall and secure the complementary parts thereof in place and a discharge flue-pipe communicating with the vertical flues of the tile-sections.

3. In a china-kiln, the combination with an exterior metallic casing, of an'oven formed of sections of tiling, having flue-passages therethrough, a combustion-chamber with which the lower ends of said flues communio cate, said sections of tiling consisting of unitable parts having interlocking members, which unite the tile-sections in the wall and hold the parts thereof against lateral dis placement, tile-sections forming the top of the oven, having passages communicating with the vertical flues and supported on the vertical tile-sections, said tile-sections forming the top of the oven communicating with the discharge-flue.

4. In a china-kiln, the combination with the exterior casing, of a plurality of hollow sills located in the base of the casing surrounding a central space, forming a combustion-chamber, the corner-sections of the sills 1o 5 being L shape and each of the sill-sections having an opening through its inner vertical wall, and a communicating opening through the top, the sides of the oven of the kiln being formed of tile-sections, having engaging members to hold said sections in position in the wall.

In testimony whereof I sign this specification in the presence of two witnesses.
