CHINA-KILN ATTACHMENT.

ToaZZ whomiz't may concern:

fBe it known thatI, DOMENIG M. CAIVF' PANA, a citizen of the United States, residing at..Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in China-Kiln Attachments, of which the following is a specification. w

My invention relates to china kiln attachments, and has'for-one of its objects the provision of a simple and efiicient attachment for inserting in china kilns, and the like, to provide even temperatures in the part of the interior of the kiln, or the like, inside of the attachment. 1

A further object is the provision'of an attachment, such as mentioned, which can be easily and quickly fitted in and taken out of a china kiln, or thelike, and one which can be easily and quickly taken apart and puttogether. Y 1 I Other objects will appear hereinafter.

Anembodiment of my invention is shown in the accompanying drawing, forming a part of this specification, and in which 7 Figure 1' is a front view of a conventional china kiln with its door open and fitted with an attachment embodying my invention.

' Fig; 2 is a side view of an embodiment of my attachment with a portion broken away to show parts of the interior; and

Fig. 3 is an enlargedsection taken on line 3-3of Fig. 2. w r

In chinai'kilns of conventional construction there are higher temperatures at the lower'portion of the-kiln than the upper due to the source-of heat being situated-in the bottom of the kiln. Also the interior. of the kiln sometimes'has drafts and other unevenly heated portions therein. These uneven temperatures in the kiln make}it difficult to fire substances, such as glassware, which have tendencies to become soft, lose their shape and collapse when heated too strongly at their base or at one special side. My attachment is to provide an even temperature, top, bottom and at the sides, making the firing of glassware or the like more perfect and correct. 7

Referring more particularly to the drawing, I have indicated a china kiln 5, which may be of any conventional or preferred form, having a door 6, which is usual with such kilns. My attachment comprises a housing or walls which have comparatively high heat conducting qualities and which Specification of Letters I 'atent.

are adapted to entirely inclose a portion of the interior of the kiln. As an example of such a housing, I have shown .a sheet,

metal housing comprising an upper portion 7 and 'a'lower portion 8. The portion 7 includes the top and upper halves of'the side walls of my attachment, and the lower half 8- includes the lower portions of the side walls and the. bottom of my attachment.- The part 7 is provided with the up per portion 9 of a rear wall, and the portion 8 is provided with the lower portion 10 of the rear end wall, When these parts are together, as indicated in Fig. 1, the sides of the housing are all closed, except the front side. This front side is adapted,

when the attachment is in a kiln, to be very.

close to and substantially closed by the door 6 of the kiln, so that there is very little or no circulation of the air in the kilnfrom the outside of the attachment to the inside thereof. This arrangement'provides means whereby the interior of the attachment is heated by the heatpassing through the walls of the housing thereof. With this arrangementvthe temperature oftheinterior of the houslngi is substantially uniform through out. Therefore, glassware, or other similar objects, can be placed in the upper and lower portions of this attachment without danger of injuring any of them. In placing glassware, and the like, in the ordinary kilns, owing to the strong heat at the bottom and at the farther part of the kiln back from the door,-a quantity of glass pieces will collapse,.while other glasses placed on shelves nearer the door or toward the upper part of thelkiln, will be fired correctly or even not fired enough to properly carry out the c olor decorations.

" The housing shown is provided with

flanges

11 and 12 on the portions 7 and 8,

respectively, with registering perforations 13 in said flanges. Inthe perforations 13 are provided pins 14. It will be seen from this construction that the upper part of the housing can be lifted directly off the lower portion when not in a kiln to separate the parts, or the pins 14 may be removed from the perforations, and the parts separated. This illustrates an easy means for connecting the upper and lower parts of the housing. At the rear of the housing on the portions 9 and 10, I provide flanges 15, or an other suitable extensions to engage the bac wall 16 of the kiln in order to hold the open side of the'housing in close proximity to the door 6 of the kiln when the latter is closed. The

flanges

11 and 12 also have the function of holding the attachment in substantially the center of the kiln and preventing the sides of the attachment from engaging the sides of the kiln, thereby insuring an air space between the sides of the kiln and my attachment at all times.

In the attachment I preferably provide a plurality of shelves so that a number of articles, such as indicated at 17 in Fig. 1, may be accommodated at one time. These shelves are preferably supported by ledges 18 on the inner walls of the housing.

The lateral edges of at least the shelf nearest the middle of the housing are preferably in close proximity to the inner walls of the housing. Hook members 19 are formed on certain of the ledges 18, adjacent the open side of the housin which engage hook members 20 on one o the shelves 21. This arrangement provides means where by the sides of the housing, adjacent the opening in the latter, are held against'lateral movements both toward and away from each other.

The top and bottom of the housing are preferably semi-cylindrical or curved upwardly and downwardly, respectively, in order to prevent forming sharp corners on the interior of the attachment, and to provide means so that the heat in the interior of the kiln outside of the housing can easily pass up around the attachment. In order to hold the bottom of the attachment above the bottom of the kiln, I have provided legs 22, which may be secured to the lower portion 8 of the housing in any desirable manner, such as by rivets'23.

While I have illustrated and described the preferred form of my invention, I do notdesire to be limitedto the precise details set forth, but desire to avail myself of such variations and changes as come within the scope of the appended claims.

I claim:

1. In combination, a china kiln having-a door atone :sidethereof; a housing in the kiln having an opening in its side adjacent the door; and an extension on the housing intermediategthe top and bottom of the latter adapted to engage the inner wall of the kiln'oppositethe door and hold the housing in a position with its open side substantially ing in said kiln and holding the open side of said housing close to the door of the kiln.v c

3. An attachment forchina kilns comprising: a housing made up of a top, a bottom, side walls and one end wall with the other end of the housing-open and said end and side walls being divided on a substantially horizontal plane; means loosely connecting the portions of saidv end and side walls together; ledges on theside walls along the division of the latter; hook members on the ledges adjacent the open end of said housing; and a shelf on said ledges having hooked portions thereonv engaging said hook members and holding the side walls against spreading.

4. An attachment for china kilnscomprising a sheet metal housing having one side open and made up of upperand lowerpore tions; means-holding the engaging edges of the upper and lower portions against rela. tive lateral displacement; ledges on the in-, ner walls of one of said portions extending alongtheadjacent edges of said portions and terminating close to the open side of the housing; hook members on the ledges at the open side of the housing; and a shelf: restingon the ledges and having partsengaging said hook members. 1

In testimony whereof I have signed mynameto this specification on, this 24th day of October A; ,D. 1917 DOMENIC M; CAMPANA.
