IMPROVEMENT IN' -PERPETUAL BRICK-BURNER.

The Schedul'erefen'ed to in these Letters Patent and making part of the lame.

To 'whom it may concern Y A Be it know'n that I, ZACHARIAH SHAW, of Ypsilanti, in the county of Washtenaw, and State of' Michigan, have invented a new and useful Improvementin Perpetual Brick-Burning Apparatus; and I do declare that the fbllowing is a true and accurate description thereof', reference being had tothe accompanying drawings, and to the lettersof reference marked thereon, and being a part of this specification. I

Figure 1 isa perspective view `of my aj'lparatus'l Figure 2 is a section showing :the endless belt.

Like letters indicate like parts in each figure.

The nature of this invention relates tothe. construc- .tiou of an apparatus for burningr bricks, whereby the bricks, as fast as burned, may be cooled down and removed, while at "the same time a ii'esh supply ol' nnburned bricks may be brought into connection with the lire.

'lhe invention consists in a new combination and arrangement of all its parts, as more fully hereinafter described. y

In the drawings-- A represents a curved chamber, whose mouth B is parallel with the surface of the ground, and thence curving upward, describing in said curve about onequ'arter ofthe arc, cfa circle, and terminatingin avertical position at any required height. v

C and C are fire-chambers, so constructed upon each side of the curved chamber, that the smoke and heat pass into the interior ot' said chamber, through l propel' openings 'u' in the walls thereof.

Any suitable boiler, in which trrgenerate steam to drive the necessary machinery employed-in the brickyard, maybe properly set above the tire-chambers, so that the same lire will make the steam and burn the brick.

D is a ventilating-pipe. j

E is an endless belt or carriage, composed of drums or wheels, chains or links, and slats or planks, and rotated in the usual manner. Its upper face should be upon a line, or a little below the line of the bottom of said chamber. 'lhc unbnrned brick are charged into the top, and

they slide down thc chamber of flue A, until they' arrive and stop near its mouth.

Athe chamber.

After a f'ew hours the brick adjoining, and just above the fire-cham bel', willbe found to be well burned. Then, by giving a forward motion 'to the carrier E, the brick in the lower part of the chamber will be thrown out of the mouth thereof. This allows the entire mass of 'f brick to slide down the chamber, bringing fresh brick into connection with the fire, and allowing-those which have just been burned, and which are now below the lire, to cool ofi' by the admission of a draught'of air into the mouth ot' the chamber, carrying off the heat through the Ventilating-pipe I).

This draught may be regulated by a door of suitiv able construction, fitting the mouth ofthe chamber..

A fresh supply of unburned brick should be added to the column in the chamber, as fast 'as burned and thrown out at the mout-h.

By a bnrning-apparatus of this construction, a con,- stant supply of unburned brick may be added to the top of the column, and as steady a supply of burned brick discharged at the mouth.

Any .appropriate material may be used in the construction of the chamber or ue A and fire-chambers.

l am aware that perpetual kilns have been built for burning and delivering lime.

I hereby disclaim anything in those kilns, and wish to confine myself strictly to the employment of this apparatus in burning brick and tile. i

What I claim as my invention, and desireito secure by Letters .Pat-ent, is-

The combination and arrangement of the curved chamber A, the carrier E, and the tire-chamber Gand G', burning brick upon both sides at once, when constructed and operating as and for the purpose set forth.
