FURNACE FOR GALVANIZIN G PUTS OR TANKS.

SPECIFICATION forming part of Letters Patent No. 515,594, dated February 27', 189%- Application filedMay 15,1393. Serial No. 74,267. (No model.)

'Moscow, in the district of Moscow and Empire of Russia, have invented certain new and useful Improvements in Furnaces for Galvanizing Pots or Tanks, of which the following is a specification.

This invention relates to certain new and useful improvements in furnaces for galvan- 12mg and other pots, and has for its object the production of a furnace, the fines of which are so arranged that the flames or products of combustion are directed first t0 the top of the pot instead of at the bottom, as has heretofore been the case, and in which the fines may be easily reached and cleaned.

To these ends therefore, my said invention consists in a furnace having a series of fines arranged outside of a galvanizing pot or tank, and in heating proximity thereto, the upper flue being in direct communication with the fire pit, and the lower flue communicating with the stack or chimney, as hereinafter more fully described and pointed out in the claims.

Referring to accompanying drawings illustrating my invention, and in the several figures of which like parts are similarly designated, Figure 1, is a top plan View. Fig. 2, is a section taken on the linewwl ig. 1. Fig. 3, is a transverse section. Fig. 4, is a transverse section taken on the line 1 ,Fig. 1. Fig. 5, is a top plan View, partly broken away,illusirating a modification of my invention, and Fig. 6, isa vertical longitudinal section thereof.

a, is the masonry work of the furnace provided with the stack or chimney b, and the fire pit c. The products of combustion generated in this pit, pass upwardly into the fine cl, which surrounds the galvanizing or other pot or tank 6, set in the furnace a. As shown in the drawings, this upper fine (1,

passes horizontally through the masonry a,

and around the top of the tank e, descending on an incline atf, to join the flue g, which also surrounds the tank e, through masonry a, and at h, descends on an incline to join the due '13, which, in the same manner surrounds the tank, communicating on the incline j, with the stack or chimney b. Manifestly the arrangement constitutes in reality but one fine passing from the fire pit, encircling the pot or tank at diiferent altitudes, and finally passing out at the stack or chimney. But I do not wish to limit myself to the exact construction herein shown and described as whenlong tanks are used,such for example as those employedin coating pipe, when more than one fire may be desirable or even necessary, the lines can pass from the fire pit or pits, extend a certain distance around the pot or tank, and then loop or double back on themselves, finally passing out at the stack or chimney, as hereinafter more fully described. The due series d,f, g, h, i, and j, is preferably constructed of fire brick, which may be fitted into one another and therefore access may be readily had to the interior of the fines to clean or repair them.

Running longitudinally through the mason ry a, and beneath the tank or pot e, is the passage way k, and from this passage, opening Z, and Z, normally closed by iron plates, or brick partitions, extend to the lowermost flue, as shown particularly in Figs. 2 and 3. Through said openings the lower loop of the flue series is readily accessible for cleaning or repairing. 1 also prefer to provide between the fiue'and the masonry the air space m, or this space may be filled with sand, or other non-conducting material, preventing the masonry from overheating, and confining the heat to the fines and the tank or pot.

It will be obvious from the foregoing that the tank or pot is protected from direct contact with the fire, and that the flames in no case touch said tank, by reason of which the tank is rendered more durable, and the liability of burning through reduced to the minimum. This end may be still further conduced by coating the tank previous to setting inside and out with a fire proofing compound, adhering to the iron, such as described and claimed in a concurrent application filed by me and designated as Serial No. 474,258 filed May 11, 1893, and when so coated, it will be found thattheinternal coating greatly reduces the formation of dress, while the heat being applied first to the upper part of the tank, and prevented from external radiation by reason of the air, or non-conducting space m, results in a great saving of fuel.

Obviously many changes maybe made in the construction described and illustrated herein without departing from the principle and scope of my invention, the gist of which lies in applying the heat of the furnace first to the upper part of a galvanizing or other tank.

In Figs. 5 and 6, of the drawings, I have shown a modification particularly adapted for long tanks, such as those used for coating pipes. In this modification, two fire places a, c, are used, preferably separated by the strip of masonry m. From each of these fireplaces the upper flue 61, passes along one side of the pot or tank, and around the end thereof opposite said fire-places, communicating through f, with the fine g, thence through h, to fiue z', thence through f, tofiue y, at or near the bottom of the pot or tank, and thence through 7, to the stack or chimney b. The fines are made into two independent series by the tongue of masonry m at the end of the tank opposite the fireplaces, and obviously as few or as many fiues may be used in the series as may be desirable but I have found in practice the construction and number herein set forth, productive of good results. It will be apparent also that the fines may communicate with each other either directly, abruptly, and at right angles, or by a gradual incline, as shown in Fig. 4, without departing from the principle and scope of my invention. Other modifications may also be made, such, for instance, as placing a fire at diagonally opposite ends, but I prefer the construction shown and described,

as it leaves the pot or tank readily accessible by the workmen. Again the fire places may be more widely separated, and extend a short distance along the opposite sides of the tank, at the same end thereof, without materially changing or altering the construction and arrangementof the fines, or other parts of the invention.

What I claim as new, and desire to secure by Letters Patent, is

1. In furnaces for galvanizing and other pots and tanks, a pot or tank, and a suitable number of vertical series of connected fines surrounding the same, the topmost of said fines communicating directly with the fire, and the lowermost of said fines with the stack 0r chimney, substantially as described.

2. A pot or tank, a plurality of fire-places at or near one end thereof, and a vertical series 3. In furnaces for galvanizing and other pots and tanks, a pot or tank, a vertical series of connected fines arranged outside thereof and in heating proximity thereto, the upper fine communicating with the fire, and the lower fiue with the stack or chimney, and a course of refractory material interposed between the fines aud the pot or tank, whereby said products of combustion are prevented from coming in direct contact with said pot or tank, substantially as described.

4. In furnaces for galvanizing and other pots and tanks a pot or tank, a suitable number of fines arranged above. and opening into, one another, and surrounding, but separated from immediate contact with the pot or tank; a suitable number of combustion chambers, and a suitable number of outlets for the products of combustion; connections from the former to the uppermost of said fines, and connections from the latter with the lowermost of said fines; the heat and products of combustion passing directly into the uppermost of said fines, thence around the pot or tank, and thence to the outlets, thereby applying the most intense heat to the most exposed portion of the metal bath in the pot or tank, and at the same time removing the heat from immediate contact therewith, substantially as described.

Signed at New York, in the county of New York and State of New York, this 9th day of May, A. D. 1893.
