UNITED STATES PATENT EETOE.

lMPROVVEMENT IN STEAM-BOILER FURNACES.
Specilication forming part of Letters Patent No. 134,243, dated December 24, 1872.
To all whom 'it may concern:
Be it known that we, A. JOHN BELL and JOHN P. FRIEND, both of Ashland, Boyd county, Kentucky, have invented an Improved Steam-Generator, of which the following is a specitiation Nature and Objects of the Intention.
Our invention has for its object aform of furnace and boilerl which shall produce the greatest possible mechanical eii'ect with a given expenditure of fuel; and this object we connect it with the boiler or boilers, in order to conserve the heat of the furnace by arrestin gthat which would otherwise escape through its walls, and causing it: to warm the water which enters the boiler; the room in which the boiler may be placed being also thereby rendered more cool and fsalubrious in consequence of the non-escape of the heat; and with this provision We combine an arrangement ot double fire-spaces, having agzcommunicating# passage andi, dampers, whereby the smoke generated inix one fire-space is consumed by being caused` to pass over the incandescent fuel in the other fire-space, so as to economize fuel, and, by burning the liberated particles of carbon, to abolish the` wasteful andi annoying smoke nuisance. In other words, our inventiony consists of a compound furnace, having twin tire-spaces communicating by means of an opening through the dividing-plate,and provided with a continuous water-space around its sides and bottom, combined and connected 'with the boiler by suitable pipes, whereby a thorough circulation of the water is insured, the generation of steam quickened and augmented, and an economy of fuel secured.
y steam-boiler furnace and steam-generator embodying ourimprovements, one of the dampers being shown open, and the other one closed. Fig. 2 is a horizontal section through the fire spaces or chambers and their iiues at the line ww, the dampers being shownin the same position asin the preceding illustration. Figs. 3 and 4 are transverse sections taken at the lines y y and z z, respectively. A
The sides or water-legs A, front B, -bottom or water-passage C, and bridge-piece D, of the furnace are composed of two distinct thicknesses of boiler-iron, having sufficient space between them to form a waterjacket.
This jacket communicates freely with the.
boiler or boilers by means of ducts or tubes E, which enter the bottoms of the boilers, and by pipes F, which lead from said boilers at a point somewhat above the bottom, to near the bottom ofthe said jacket, or to a part of itlower than the duct E. These pipes, when leading from the boiler top, as shown, may have their receiving ends submerged, as at F. These' pipes and ducts insure a perfectly free circulation between the boilers and the jacket. The opposing sides of the jacket are secured by customary stay-bolts M. The furnace proper is composed of two or more fire chambers or spaces, G G', whose dividing-wall or partition L, stopping short of the fire-front, leaves between each two adjacent chambers a passage, l. H H are ilues which lead from the respective firefchambers. I I are dampers by which therear end of either nre-chamber may be closed, so as to compel its smoke to traverse the adjacent chamber and nd vent through the flue thereof. J represents theepipe from the feedpump. K are man-holes, of which there are several at each end ofthe jacket, near its bottom, to afford access to its interior for' a swab or other cleaning instrument or appliance, as, for example, a steam-j et. T may represent customary blow-off cocks for the discharge of mud and scales or sediment.
Operation.
The action of the water -jacket has been explained 5 that of the furnace is as follows: As soon as the res of the contiguous chambers have reached the condition of incandescence, and itis desired tof1re up, the chamber which is to receive the fuel is closed by shutting its damper; the smoke from this charge, being unable to reach the due directly,
' 13eme escapes through the adjacent chamber and is Jthere entirely consumed, so as to completely utilize the fuel and convert all the combustible elements into gases, which escape unseen and unaccompanied by smoke. The next charge is, of course, put into the adjacent chamber, which, having been in turn closed and its neighbor opened, discharges its smoke through the contiguous and now incandescent chamber or chambers, with the results already stated, and so the process is repeated. by the alternate use of the respective fire-chambers.
We are aware that twin furnaces, substantially such as herein described, are old, and also that boilers and furnaces jacketed to hold water, and having circulating pipes not essentially different from those employed by us, have been in use, and We therefore make no claim separately to either of these features. W e are also aware that a boiler having waterlegs substantially such as employed by us has been arranged in conjunction with a twin furnace, but such arrangement and construction did not possess our water communication below the ash-pit-a provision which we deem of vital importance in such generators; such arrangement, apart from such Water-hearth or ash-pit floor, therefore, we do not claim; but 'Ve claim as new and of our invention- In combination with a steam-boiler, the twin-furnaces G G', having the division-plate L and communicating passage l, and provided with the water-legs A and Water-passage C, all constructed and arranged substantially as described, and for the purpose set forth.
In testimony of which invention we hereunto set our hands A. JOHN BELL. JOHN P. FRIEND.
