IMPROVED Bares-Kan.-

TO ALL WHOM IT -MAY CONCERN:

Be it known that I, WILLIAM A; SHEPARD, of the city of New York, in the county of New York, and State of New York, have invented a new and useful improvement in Kilns for .Heating and Hardening Bricks, Tiles, or other substances; and I do hereby-declare that the following is a full, clear, and exact description thercof,'rofcrence being bad to'thc accompanying drawings, and to the letters of reference marked thereon. Inv

the accompanying drawings- Figure 1 is a side elevation of a kiln constructed according to my invention; and

FigurcQ is alike view with the side wall removed to show the interior structure of the kiln.

I build an oblong room of brick, or other suitable material, of any convenient size, say eight feet wide, forty feet long, and ten feet high, and lay a railway track through the same, terminating at each end conveniently for loading and unloading the cars hereinafter described. I divide the long room into as many compartments as may be desirable by vmeans of movable sheet-metal partitions, which slide up and down, but which co1npartments communicatealternately through open spaces at the top and bottom of said partitions, and thus a current of hot'ai'r passes under one partition and over another. through the entire length of the room. I constructa car for each compartment, which ear'ha's a fire-brick platform upon which I build a brick-kiln, or place other materials for burning or drying. g

In the accompanying drawings A A is-the outer brick wall of the long room, above described, anda adoors to close the openings in said wall, through which fuel is introduced into the arches of the kilns. C C are the cars, upon the fire-brick platforms 0 of which the brick-kilns B are built. 'Thcse cars main and out upon railway tracks t. pp are the sliding partitions between the different compartments, with spaces alternately under and over them for the hot air to pass through, as above described. R is a roof covering the long roomand enclosing it, with openings for the partition-plates to slide up and down in.

The fire-brick platforms of. the cars are on' a level with the lower part of the openings in the outer wall through which the fuel is introduced. The cars, having each a brick-kiln built thereon, are drawn into the loiig.

room, one in each compartment, and the several partitions lowered down. Thecnd doors of the long room are then closed, and all the side doors 11, except the one most distant from. the chimney, through which opening a fire is built in the first compartment or kiln. When the fire begins to burn a draughtwill be created, which will convey the flame and hot air through-all the compartments and out at the chimney, passing alternately under one partition and over another, as above described, drying and seasoning the bricks in the kilns, which as yet have had no fire under them. When the first kiln is nearly burned or hardened, I place fire in the second kiln and increase it at pleasure, and when the first kiln is finished the car supporting it is drawn out and its place taken by the second kiln, and the last compartment is supplied with a fresh kiln.

When brick are made of wet clay the room should beimade longer, or a second story should be constructed for the purpose of drying the-brick on the principle of a return-flue, with the'ehimney at the front end of the room. 1

What I claim as my invention, and desire to secure by Letters Patent, is-- p 1. An oblong building with a railroad track running through its whole length, and divided into separate compartments by means of removable partitions, in combination with a series of cars having fire-brick, or other equivalent platforms, and adapted to building kilns thereon, and burning the same on the cars,-substantially as;

described.

2. I also claim building and burning kilns of brick, pottery, or other similar substances, on movable railroad cars, with platforms of fire-brick, or equivalent material, substantially as described.
