IMPROVEMENT 'IN BRICK-KILNS.

Specification forming part of Letters Patent No- 220,213, dated October 7, 1879; application filed September 1, 1879.

To all whom it may concern:

Be it known that I, DANIEL ASBURY, of Charlotte, in the county of Mecklenburg and State of North Carolina, have invented a new and useful Improvement in Brick-Kilns, which improvement is fully set forth in the following specification and accompanying drawings, in which- Figure l is a view in perspective of my kiln. Fig, 2 is a horizontal section of the same on the line 00 a of Fig. 1. I

The object'of my invention is to build a brick-kiln which shall be simple in its construction, effective in its operations of burning, and insure a greater saving of time and fuel than has heretofore been done.

My invention consists in arranging the bricks in the side walls or pillars of the firearches so as to leaye small air spaces or flues leading from the fire-arches into a continuous flue, which extends the entire width of the kiln through the walls or pillars of the arches, so that theproducts of combustion will receive airdrafts from both sides and throughout the entire length of the fire-arches or furnaces.

111 the construction of kilns heretofore the walls, pillars, or benches of the fire-arches or furnaces have been built up solid, and the ends of the arches or furnaces left open, so as to admit the air from the door or end of the furnace over or under or through the fuel. Benches of a permanent character have also been made in brick-kilns of iron, brick, fireclay, 8250., with air spaces or channels entering the furnaces above or below the grates. They have also been made with hollow walls or pillars of the fire-arches, with'flues admitting air on a level with the furnace; but said lines have only extended part way through the kiln, and as a consequence thebricks in the center of the kilns are not uniformly or sufficiently burned.

To cheapen and simplify the construction of kilns of this character, and to obviate the defects above named, I build my walls or pillars the entire length of said walls or pillars, as shown at A.

.In building the sides of the walls or pillars I leave out a brick here and there from the bottom course. I may leave out every other brick, or have two, three, or more bricks laid close together in groups, and then an open space, which connects the furnaces or fire-arches with the lines A, thus forming a series of small flues for the admission of air on a level with the bottom of the furnaces or fire-arches.

The small flues are shown at B, and may be arranged so as toenter or open into the fire arches or furnaces directly opposite to each other, or they may alternate. I prefer, however, the former arrangement, for the reason that the air-currents meeting in the bottom and center of the firearches tends to increase the draft, making the combustion more complete, and distributing the calorific currents directly to and around the mass of bricks above.

O are the fire-arches or furnaces, which extend the entire width of the kiln and are closed at both ends by a door, D.

In this kind or construction of a kiln wood is preferred as a fuel, and it is fed in at both ends of the furnace or fire-arch, and pushed toward the center, so that theentire arch is a furnace; and by this means the bricks in the center and sides of the kiln are burned uniformly, the combustion is more complete, and thus a saving of time insured, and, necessarily, a saving of fuel.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

The combination of the continuous fire-arches or furnaces with the sm all lateral fines or open .ings and the continuous fines or air-passages
