v The Schedule referred to in these'Lettexs Patent and making part of the sama.

To all whom itmay conce/m:

Be it know'n that I, J Aeon K. GOOD, of -Pequa township, in the county of Lancaster, and State of Pennsylvania, have invented a new and improved Mode of Charging and Discharging Kilns for Burning Bricks; and Ido hereby declare that the following is a full description ot'my kiln, and operation of the same, reference being had/to the accompanying drawings, making a part of this specification, in which'- Figure 1 -is a perspective view of my kiln, showing the open base and central square stack.

Figure 2, a verticallsectilon, showing a series of 'six charges, and other appliances in profile. l

Figure 3 illustrates a modification of the device for elevating the platform and car.

Figure 4, the arrangement of united grate-bars, with side-racks and pinions.

The nature of my invention consists in building up a series of charges, (say, of four hundred or more blicks liu-each one on top of the other, in a vertical stack,

having a removable grate, or separate bars, so as to open the throatof the stack its full width into an open arch-way, and furnished with side-furnaces, for keeping a continuous tire, and so that when the charge next the re is suiiiciently burned, it can be'withdrawn, and the next charge above brought in its place.

To enable others skilled in the art to make and use my invention, I need simply refer them to my drawings.

Fig. 1 shows aY rounded base, B, with a road-way,

vB R, and rails, leading through atunnel in the rounded .superstructure A, in two sides of which are furnaces,

ash-box, grates, &c., constructed in the ordinary, or most approved style in use for side-furnaces.

Centrally, is shown a square stack, H, of any desired lheight and dimensions, whether of cast plates or masonrly, This stack -is open below into the road-way.

In this road-way is a sunken platform, G, with segments of rails to match those on the road-way, (if rails for the car are used.) Y

This platform is connected, at its four corners, with,

say, screw-rods, S, passing through a heavy cross-piece,

D, on top ofthe superstructure A.

Across the road-way, burrs, to he lworked with a wrench, are shown, for raising the platform. Amore speedy mode for doing the saine is shown by iig. 3, by means of four chains, M', connected with the platform (Jh-passing over pulleys, K., and connected to alever, L.

The ends of the levers are united on each side, and a chain, M,`attached, passing around a ground-pulley, O, and connected with a drum, or windlass, Q, provided with a pawl and ratchet, said chains M, from the projecting ends of the two pairs of levers, being reversely attached, so that the wiudlass will draw upon both in unison, and thus draw up the platform, with the car upon it, against the under side of the stack. The bars are then drawn out, when the burned charge of brick will rest upon the car adapted to the pile, and lowered down until the next charge above has settled down, the base of each charge being adapted to receive the bars of the supporting-grate, which are now replaced, and the car lowered down to the road-way with the charge No 1 on it, (see iig. 2,) and charge No. 2 in its place, subjected to the direct action of the fire im the side-furnaces F. The other charges, 3, 4, 5, receiving the spent heat, are being rapidly' dried, or partially burned, while a new charge, 6, is built on top, adapted to the movable grate-bars in the bottom of the stack, by building the charge on or over like bars, so as to fit with ease, when finally lodged, as the lower charges are withdrawn, andthe upper charges successively-brought down, burned, and removed, in the manner specified. i

I am aware that an inclined kiln is used, and trucks employed, like in patent No. 60,029, where chargesof brick are burned and removed, claiming certain cars,

with their running-gear, as also supplemental cars, the groove-way in the tunnel, as also the trucks passing through the furnace. Such I do not use or claim.

' Iam `aware, also, that cupolas, curved below, charges on rods andchutes, and an endless apron, are used, as also a top platform, and various devices; but I am not aware of any mode ever beingr used in which the series of charges are vertical, one on top of the' other, in a straight stack, from which the burned brick are taken out below, and the fresh-made or pressed brick stacked or set in above, as fast as they areburned and withdrawn below, by any known mechanical means to effect the same, or substantially in the manner specified; therefore, Y i

What I claim as my invention, and desire to secure by Letters Patent,l is- The arrangement herein described,`viz, of setting the charges of brick, one on top of the other, within the cupola H, having side-furnaces, F, on an elevated base, A and B, in combination with the removable base, and hoisting-apparatus for elevating the platform G, with car C, substantially as set forth.
