LEWIS C. ENGLAND, OF PHILADELPHIA, PENNSYLVANIA.
IMPRovMENT IN FuRNAcEs.
Specification forming part of Letters Patent No. 154,133, dated August 18, 1874; application filled July 14, 1874.
To all whom it may concern:
Be it known that I, LEWIS G. ENGLAND, of the city of Philadelphia, State of Pennsyl- Vania, have invented an Improved Furnace, of which the following is a specification:
My invention has for its object the saving of fuel and labor in attending a furnace, as well as the successful burning of the smoke and gases, being particularly well adapted to the burning of such fuel as wet spent tan-bark, bituminous coal, &c. It is more economical in the consumption of fuel than any furnace heretofore known to produce heat under steam-boilers and for other useful purposes, being self-feedin g and the grates self-cleanin g, requiring but little attention after once properly adjusted.
The annexed drawing shows the principle and manner of its construction and operation.
The grates A are an endless chain of castiron coned perforated plates, passing over properly-constructed pulleys B B at either end, driven by any suitable device for very slow or faster motion, as occasion may require, and linked together at the ends by small iron plates, arid being arranged crosswise of the lire-chamber O. They are cast with as many small holes as can conveniently be made in the pattern to cast from, and a length corresponding to the width of the fire-chamber, and ten to twelve inches wide, with journals at the ends, which pass throughthe ends of small iron plates, which link them together, thus forming an endless chain of cone-grates. Placed near the center of each shaft, on which the drivingpulleys are placed, is a grooved pulley, over which a common wroughtiron chain passes under the grates, to steady and keep them inA place. The hopper or funnel D Dis lled with fuel, and should be kept full. One side of the funnel D is formed'in part by the outside of the bonnet E and the hre-front F. The other side of the funnel and the hopper may be made of light boiler-iron. The lower portion of the fuel in the funnel will rest on the top andwfront end of the movable grates A, and, by havingrpassed through the funnel slowly, in contact with the heated bonnet and fire-front, will be heated by the time it is carried by the moving grates into the nre-chamber, so that it will burst into ame'immediately. Much if not all of the smoke and gases will be consumed by passing over the hot coals that will be distributed evenly over the surface of the grates, and
through the hot coals and the perforated plate G. No sparks will be developed, the feeding of the fuel is so gentleand regular. Fire-bricks are used for the inside lining of the furnace, and under steam-boilers a number of wallsof that material may be constructed and used to retain the heat at the rear end of the furnace. One, H, arched up to the boilers, is placed in front of the rest, directly over the grates, or more than one may be thus employed. There may be a number of divin g-ilues thus arranged of this material beyond the farther end of the grates, and continued to the farther end of the boilers. The perforated plate G, placed at the rear end of the movable grates, which receives the unconsnmed fuel, lcinders, &c., is placed on journals at the ends, on the side nearest the grates, 'and held in place by a crank, and, vwhen requiring cleaning, can be put into a vertical position by a movement of the crank by hand, thus allowing the cinders, 8vo., to fall into an ash-pit below left for that purpose.
The draft, after passing through the perforated plate Gr, will enter the line again at I, passing through the fines to the rear end of the boilers; then, through the return fluesor tubes, to the bonnet E, which communicates with the chimney.
The adjustable gate K is made to move up or down, so as to allow more or less of the fuel to enter the fire-chamber.
Near the bottoln of the funnel is placed a toothed shaft, L, which is to revolve slowly, and may be geared to move with the grates by the same driving-gear. This will mix and loosen the fuel on the grates.
I claim as my invention- 1. The combination of the smoke-box E, for heating the fuel, with the hopper and funnel D D, substantially as described.
2. The combination of the perforated dumping-plate G with the endless chain-grate, substantially as described.
3. The toothed shaft L, in combination with the funnel D and chain-grate, substantially as described.
4. The adjustable gate K, in combination with the toothed shaft L and funnel D, substantially as described.
