KILN FOR DECORATING PORCELAIN OR GLASS.

SPECIFICATION forming part of Letters Patent No. 569,232, dated October 13, 1896.

Application filed April 18, 1893. Renewed October 30, 1895. Serial No. 567,4:53. (N0 model.)

To all whom, it may concern:

Be it known that I, JOHN PHILLIP]? RIEF- FEL, a citizen of the United States, and a resident of New York city, county and State of New York, have invented certain new and useful Improvements in Kilns forDecorating Porcelain or Glass, of which the following is a specification.

This invention has reference to an improved portable kiln for burning decorated articles of glass and porcelain, said kiln being so constructed that the same can be put up and used at any suitable point without the least danger of fire and that the articles can be readily observed during the burning process and finally removed from the same after the burning is completed, upon which the ashes are readily removed from the kiln afterco0l ing, the same being then ready for receiving the next charge and going through the next burning process.

In the accompanying drawings, Figure 1 represents a front elevation; Fig. 2, a vertical transverse section on the line 2 2, Fig. 3; Fig. 3, a vertical longitudinal section on the line 3 3, Fig. 2. Fig. 4 is a plan view of the movable grate and muffle-support; and Fig. 5 is a horizontal sectional view on the line 5 5, Fig. 2.

Similar letters of reference indicate corresponding parts.

The walls A of the kiln are constructed of two layers of sheet metal, between which bricks of fire-clay or any other suitable noncombustible and non-conducting material are arranged. The top B of the kiln is constructed in the same manner and is provided with openings B for introducing fuel, which openings can be closed by covers B also made of sheet metal with a filling of nonconducting and non-combustible material. Each cover has a handle or rod 13'" for lifting the same on and off. Said covers are locked in closed position by bars 0, passing under angle-clips O on the top of the kiln, through which bars screws 0 are passed, which serve to press the covers B down in place. In the top of the kiln two flues D D, each having a damper D D, are arranged, the upper ends of said fines terminating in the lower end of a larger flue E, having a damper E. In the bottom of the kiln a series of cross-bars F are arranged, between which plates F, of fireclay, are fixed, so as to form a support for the muffies, said layers of fire-brick F extending to within a short distance from each side and end of the kiln.

Along each side of the kiln and the ends of the same two U-shaped cross-bars G are arranged, which are provided with lugs G G for guiding them in the slots in the hollow metal base H of the kiln, said grate-bars G each being provided with a handle G by means of which they can be moved in the direction of the length of the kiln. This grate can therefore be used for shaking down the fuel and stirring the fire in the chamber surrounding the muffle. As shown in Fig. 2, said grate-bars G are arranged a short distance below the bars F and plates F.

Below the kiln a fire-box J is formed, the sides of which are inclined inward and downward, said fire-box having a lining J, of fireclay. A grate K is held in the bottom opening of the fire-box and in the top of an ashbox K, on the top edge of which ash-box the fire-box rests. The grate K is supported by a series of L-shaped irons M,having shanks of different length, each shank being provided on its end with an arm M. hen said L-irons M are held in the position shown in full lines in Fig. 2, the grate is in the raised position and is in the bottom part of the fire-box. When said L-irons are placed in the position shown in dotted lines in Fig. 2, with the shorter shank projecting upward and the longer shank horizontally, the grate is lowered to about half the height of the ash-box. This change is effected by withdrawing the screw M and shifting the iron from one of said positions to the other. This permits of using a greater amount of fuel, as may be necessary for some articles that require a longer time for baking.

The front of the ash-box is closed by a removable cover N, which is locked in place by a bar N, the ends of which rest under angleclips N on the end of the ash-box, said bar N being provided with screws N for drawing it up tight. The fire-box is provided with a hinged end gate 0, that is locked in place by means of a bar 0, the ends of which rest under angle-clips O on the end of the firebox, said bar 0 having screws O for pressing the door 0 firmlyagainst its seat. By means of the screws 0 and N the doors of the firebox and ash-box can be looked very easily, so as to absolutely prevent any ingress of air during the cooling operations.

The kiln A is closed by a removable end gate 1?, having handles P, and is locked in place by a bar Q, the ends of which rest under angle-clips Q on the end of the kiln, said bar Q being provided with screws Q for pressing the end gate P firmly against the seat. This gate P has an opening for receiving the end of a conical extension R of the muflie R, resting on the floor formed of the bars F and the plates F, the end of which conical extension R forms a peep-hole that can be closed by a swinging gate R pivoted on the outer surface of the end gate P of the kiln. The muffle R has a series of shelves S and may contain an additional muffle T, provided with shelves T. From the top of the muffle a flue U extends into a fine II on the top of the kiln, the upper end of saidflue U extending into the bottom of the main flue E. A damper V is provided in said flue U. By this arrangement of the fines and dampers the heat can be controlled, regulated, and equalized throughout the kiln.

The kiln rests on the stand XV, made of iron bars.

The articles to be burned are placed in the mufiles and the space between the muffles and the sides of the kiln is filled with charcoal, which rests on the grate-bars G. The space between the bottom of said grate-bars G and the bottom grate K is also filled with charcoal and the fire, is started. After the muffles have been heated to the desired degree all openings are carefully closed, so as to prevent any air from entering the kiln while the same and the articles therein are cooling. The draft in any part of the kiln can easily be regulated by means of the dampers described, and the fuel can easily be placed in the furnace and the ashes removed through the several openings above described.

As all the parts of my improved kiln are made of materials that can resist the fire in a high degree and by which the radiation of heat is prevented, nearly the full heat is utilized in the burning process, so thata perfect and effective burning of the article is obtained. The kiln is portable and can be put up at any floor of a building, without requiring to be walled up and made a permanent structure. It is of special advantage for all those trades which decorate small articles of glass and porcelain with colored enamels that are fixed onto the goods by burning.

' Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a portable kiln, the combination of a fire-box, a casing above the fire-box, amuflie supported in said casing, a fuel chamber around said mniile within said casin g, and an oscillatory grate between said fire-box and fuel-chamber.

2. In a portable kiln, the combination of a fire-box, a casing above the fire-box, bars extending across the bottom of said casing, heat absorbing and radiating plates disposed between said bars and forming a central floor, a muffle supported on said floor, and a fuelchamber around said muffle within said casing.

3. A kiln for burning articles of glass or porcelain composed of a base-frame, transverse bars, plates between said bars, amuflie supported on said bars and plates, a casing on the base-frame and surrounding the muffle, and U -shaped sliding grate-bars below the muffle and its support for supporting the fuel between the walls of the muffle and the easing, substantially as set forth.

4:. In a portable kiln, the combination of a fire-box, a casing above the fire-box, anouter muflle in the casing, an interior muffle in the lower part of the outer muffle, the upper part of said outer muffle being fitted with removable shelves, and a fuel-chamber around said outer mufile within said casing, substantially as set forth.

5. In a portable kiln, the combination of a fire-box, a casing above the fire-box, two damper-equipped flues extending from the top of the casing and merging into an enlarged main flue, a muffle in said casing, a conical flue extending from said muffie through the top of the casing, a damper-equipped conical fine of larger diameter than the top of said muffleflue, mounted on said casing, and surrounding said muffle-flue, said casing-flue extendlng into the enlarged main flue at a point between the converging flues, and a damper in the enlarged main flue, substantially as set' forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
