UNITED STATES PATENT OFFICE.
JOHN HOIVELL SHANK, OF GALLIPOLIS, OHIO.
SMOKE-CONSUMER.
SPECIFICATION forming part of Letters Patent No. 323,217, date-d July 28, 1885.
Application filed October 18, 1884 (No model.)
To aZZ whom zit may concern Be it known that I, JOHN H. SHANK, a citizen of the United States, residing at Gallipolis, in the county of Gallia and State of Ohio, have invented certain new and useful Improvements in Smoke-Consumers; and I do declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon,which form a part of this specification.
My invention has relation to smoke-consumers; and it consists in certain novel eonstrnctions, combinations, and arrangements of parts, as will be hereinafter more fully described and claimed.
In the drawings, Figure l is a plan view of my furnace with the top removed. Figs. 2 and 3 are side views of the opposite sides of same with the casing broken away to show the internal arrangement. Fig. 4 is a front elevation of the furnace. Fig. 5showsa modification.
The furnace at is preferably brick-work of ordinary make-up, and is provided with the chimney C, in which is placed a damper, 0, usually of the butterfly valve variety, as shown.
The boiler B is of that form having longitudinal flues running from the rear end to the front end through the water-chamber thereof. The boiler is set in the brick-work of the furnace so that fully one-half of its diametric length is incased and subjected to the action of the fire.
A flue, A, extends from the fire box or chamber A back under the boiler and along the incased side thereof. The flue A is turned at its rear end so as to direct the heat and smoke into the rear ends of the longitudinal flue-pipes in the boiler.
At the front end of the boiler a connectingflue, D, is arranged to take the smoke as the latter leaves the boiler and convey it into the chimney O. The damper O is placed just above the discharging end of the flue D.
A fan-case, E, containinga suitable fan, E, driven by suitable connections with a steamengine or other motor, is located alongside of the furnace and adjacent to the chimney. The fan case is connected with the chimney by a pipe, F.- The pipe F has its receiving end in thesame horizontal plane with the discharging end of the connectingflue D, and its other or exit end enters the fan-case at the upper sidethereof, as shown atf. IVhenthe damper O is closed, the smoke passes without obstruction directly from the flue D into the pipe F.
The exit E of the fan-case is at the lower side thereof and on the same plane with the flue A, and is connected with the latter by one or more pipes, G. By the arrangementof these several fines and the fan-case as described a perfect circulation is secured from the furnace through the boiler-chimney and fan-case back into the main flue A just in rear of the fire-pot. The circulation varies but slightly from a horizontal plane, and requires very slight forced draft to cause the smoke to make the circuit.
A series of pipes, G, are used in order to avoid the use of one large pipe. A large pipe would take up too much room and would obstruct the draft in the flue A. If onelarge pipe were used, I would not carry it across the flue A, but would have its open end at the side thereof. By using a series of pipes and extending them across the flue A and close to the bottom thereof, and having them perforated wit-h a series of openings which discharge upward, I secure the needed capacity for discharge. The smoke is discharged in numerous small jets, which are caught in the first waves of heat from the fire-chamber- The pipes G are arranged, as shown, transversely to the flue A, and in close proximity to the fire-pot, so that the hot flames will pass over them and take up the smoke as it is discharged from small openings. It will be seen that the smoke is very little exposed, whereby its heat will be taken away from the time it leaves the fire-chamber till itis discharged from the pipes G into the flue A.
To further assist in the combustion of the smoke, I provide a hot-air pipe, I, which has its inlet end 2' arranged at the frontof the furnacewall and on the side of the boiler opposite the fan. The inlet end is arranged above the fire-pot near the roof of the furnace. Above the fire-pot, and at such distance there from as will remove it from direct contact with the flames and preserve it from injury, it is subject to'a degree of heat sufficient to heat it and heat the air as soon as the latter shall enter it. boiler, and is depressed below the rear end of the boiler into the rear end of the flue A and to a plane below the end of the boiler, as shown. It is bent so as to pass to the opposite side of the boiler, where it is inclined upward opposite the upper side of the fan-case. It is then bent outward and carried through the furnace -wall and into the fan case at z. The air will be heated to a very high degree before it will have passed half the length of the pipe I, and will be preserved at this high degree till it enters the fan case. The rear end of the pipe I is out of the way in case it be necessary for workmen to do anything at the rear end of the boiler. An opening can be made in the rear wall of the furnace, and repairs or other work done to the boiler without disturbing the pipe. The rear end of the pipe, being in the flue, is subjected to a high degree of heat, butis far enough removed from the fire-pot to be out of danger by burning. The outer end of the hot-air pipe may be partially or wholly closed when desired by a valve or cap, J, which is pivoted at j so that it can be turned to any desired position.
Instead of carrying the pipes G directly into and across the flue A, they could be arranged to discharge below the said flue.
In Fig. 5 the discharge from the fan enters at and passes up through a grating, H, in the bottom of the flue A, arranged in rear of the fire-pot gratings A.
The operation of the device will be fully understood from the foregoing description. The smoke, by my construction and arrangement of parts hereinbefore described, is kept It is carried back alongside the constantly hot, and when discharged into the flue A does not obstruct but increases the draft of the furnace.
I am aware that it is not new in smoke-consumers to have a fan fed by hot air drawn through a pipe arranged in or close by the furnace, and I do not claim, broadly, such construction.
In my device the novelty lies in the arrangement of the several parts, whereby greater economy is secured with less complication of parts.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s
The herein shown and described smoke-consuming furnace, consisting of the following elements in combination: the furnace a, chimney 0, located in front of and to one side of the furnace, the boiler B, set to project beyond the front wall of the furnace and form the flue A beneath and in the rear of the boiler, the flue D, connecting the front of the boiler with the chimney below a damper located therein, a fan-blower, E, connected with the chimney at a point below its valve, a hot-air pipe extending around and in the rear of the boiler and connecting with said fan-blower, perforated pipes G, extending transversely across the flue Ain the rear of the fire-chamher, and the pipe E, connecting the fan-blower with the discharge-pipes G, the parts being constructed, arranged, and operating in the manner substantially as shown and described.
In testimony whereof I affix my signature in presence of two witnesses.
JOHN HOW'ELL SHANK.
