SPECIFICATION forming part of Letters Patent No. 527,255, dated October 9, 1894.

Application iiled April 14, 1894:. Serial No. 5075601 (N model-3 To all whom it may concern:

Be it known that I, WILLIAM A. WILEORD, brick-maker, of Todmorden, in the county of York and Province of Ontario, Canada, have invented certa-in new and useful Improvements in Brick-Kilns; and I hereby declare that the following is a full, clear, and exact description of the same.`

The object of this invention is to build a brick kiln of a series of independent adjacent chambers with intervening walls having horizontal passages formed therethrough from chamber to chamber to permit of the passage of the heated gasesand flames from one chamber into the next adjoining chamber, in order that a continuous fire can be kept up thereby, and also provideeach of the chambers with a series of openings formed through the end walls to admit of a current of air to assist combustion within the chamber, and also to provide each chamber witha series of openings through the top to admit of the entry of the fuel to feed the fire within the chamber, and also to provide each chamber with a separate outlet to permit of the escape of the gas from the chamber to a main flue, and to provide an outlet from the main iiue to the atmosphere, the whole devicebeing arranged as hereinafter more fully set forth and more particularly pointed out in the claims.

In the drawings: Figure l is a perspective View showing a series of fourteen independent adjacent chambers, with the outer structure removed. Fig.` 2 is a sectional plan view of Fig. 1 showing the arrangement of the chambers, and the relation of each chamber to the chambers next adjoining. Fig. 3 isavertical sectional View of two of the chambers on the lines a-a Fig. 1. Fig. I is an end elevation. Fig..5 is a perspective view of the complete structure partially in section, Fig. 6 isatranverse section al view ofthe brick kiln.

Like letters and numerals of reference refer to like parts throughoutthe specification and drawings. j,

The kiln consists of a series of independent adjacent chambers numbered 1 to 14 respectively. Each of these chambers is provided at its front end with an opening A to admit of the entry and removal of the brick to be burned.- This opening Ais closed when the chamber is filled by metallic plate B.

Formed through the front end wall C of the chamber 1 are a series of passages l) to permit ofthe entry into the chamber 1 of `a sufflcent current of air to support combustion Within the chamber. Formed through the top of the chamber l are aseries of openings E through which the fuel is introduced into the chamber. Separating the chamber l from the chamber 2 is a partition'or dividing wall F, and formed through this partition or di viding wall F are a series of horizontal openings Gr to permit of the passage of the name and heated gases from the chamber l to the chamber 2, when it is necessary or required to draw the re from the chamber l into the s chamber 2.

To close the horizontal openings G I provide a series of dampers 2a connected together and operatedby a damper rod 2b. As each of the chambers is provided with horizontal openings similar to the openings G, it will not be necessary to describe these openings in connection with the remaining chambers, as each of these openings is closed by a similar damper plate operated in a similar manner.

To provide for the escape of the gases from the chamber 1, while the tire is contained in the said chamber, I provide the chamber 1 with a supplemental tine H extending beneath the base of the chamber and dischargf ing into a main flue I located and extending along the back of the chambers. It will be noticed that the opening J into the supplemental ue I-I is located at the front end of the chamber 1 and adjacent to the partition or dividing wall F, and that the gases are drawn to and taken from the front end of the chamber 1 by means of the opening .I and `supplemental line H, and are conducted from the chamber 1 into the main flue I, from whence they are conducted to a stack K,and

then discharged into the atmosphere at a suitable elevation. Formed through the side IOO might here be stated that each of the openings B extends to the top of the structure, and

the iiue C, and its spur or branch F into its respective chamber, or while the heated air is discharging from the heated chamber into the ue, that is, for instance: If the brick in the chamberl has been burned, the plate G would be removed to permit of the heated air discharging into the spur or branch F and flue C, in order that the heated air could be conducted to some other chamber; but in the event of the fire being in, say chamber 12, the heated air from chamber No. l2 would be conducted by means of the flue C to the chamber 1, in order that the chamber l could be dried in advance of the fire reaching it. The flue C discharges into the openings B", in the same manner as above described, and the flue E discharges into the rear end of the chambers in the same manner. As each of the chambers is provided with a damper plate G', it is possible to take the heated air from any one chamber' by means of the aforesaid fines, and convey it to any other chamber.

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

1.,In a brick kiln, a series of independent adjacent chambers with intervening walls between them having horizontal passages opening from one chamber into the next adjoining chamber, two main iiues, one of said chambers discharging into one of the main iiues, and the next adjoining chamber discharging into the other main flue, and means for conveying the gases from the main iiues and discharging them -into the atmosphere,

each of said chambers provided with a series of draft openings to supply a current of atmospheric air to the fire Within the chamber, and means for supplying fuel to the fire within the chamber,substantiallyas specified.

2.In a brick kiln, a series of independent adjacent chambers, with intervening walls, horizontalpassages connecting the chambers, means for closing the said passages, two main iiues, a supplemental flue for each of said chambers, discharging into either the one or the other of the main iiues, and means for conveying the gases from the main iiues, substantially as specified. p 3. In a continuous brick kiln the combi- 55 nation of a series of independent adjacent chambers, two central longitudinal main iiues between the rows of chambers, a supplemental iue for each chamber, the supplemental iiues of the alternate chambers discharging into one of the main dues, and the supplemental fines from the intervening chambers discharging into the other main iiue, an outlet' from the main dues, aseries of passages formed through the walls of each of the chambers to admit of a current of atmospheric air to the chamber, a series of vertical passages formed through the top of each of the chambers to admit of the entry of the fuel to the chamber, a series of horizontal passages formed through the dividing wall or partition between the adjacent chambers to permit of the fire being drawn from one chamber into the other, substantially as specified.
