FURNACE.
SPEGIFICATION forming part of Letters Patenta No. 561317, datecl June 9, 1896. Application filed January 9, 1895. Serial Ne. 534,&05. (Ne model.)
To all whom it may concern:
Be it known that I, WILLIAM L. Ross, residing at Omaha, in the county of Douglas and State of Nebraska, have invented certain useful Improvements in Furnaces; and I do hereby declare that the following is a full, clear, an d 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 accoinpanying drawings, which form a part of this specification.
This invention has relation to a new and novel improvement in furnaces.
The object of myinvention is to provide a fuel-economizing furnace.
In the accompanying drawings, Figure 1 shows an end sectional view showing the arrangenent of the fines and tubes, while Fig. 2 shows a sectional side elevation with parts removed.
A represents a suitable casing, of any suitable size and material, through which I extend a wall B', as is shown more clearly in Fig. l. This wall divides the lower part of the furnace into two compartments O and P, the compartnient O working in the Capacity of a cold-storage chamber, while upon the opposite side the conpartment P forms the ashpit. The upper portion of the chamher O is provided with a deck 2, so as to divide this chanber, while the upper portion of the ashpit is provided with the grate-bars 3.
Extending from the deck 2 is a divdingwall I, preferably extending the full length of the furnace, as does also the dividing-wall B. Above I provide the furnace with 'a hotair chanber C, which may extend the full length and may extend clean across, but preferably covers but one-half of the upper portion of the furnace. Entering the cold-air chanber O is an ordinary supply-pipe F, led to without the furnace and building. Ex
tending from this cold-air chamber are a series of pipes D, which are broken off in Fig. 2, which extend upwardly until they escape the wall B, and then laterally across the firepot and above the grate-bars until they strike the wall of the fnrnace, and from thence they are again directed upward, and, again recurving, enter the hot-air chamher C, as is clearly shown in Fig. 1.
The fire-pot proper is provided upon each side with additional hot-air flues, which (30111- municate with the fresh-air-supply pipe F, as is shown in Fig. 2. These tubesE are provided with a Valve B and extend from the supply-pipe F upward and enter the furnace on the grate-line, then pass forward upon one of the grate-bars until the forward portion of the furnace is reached, when they extend Upward and then rearward approxinately the height of the wall B, this upper rearward extension of the pipe being perforated, as shown in Fig. 2. This pipe E is then extended upward and again passes forward in the shape of a. reversed letter S, the upper portion also being perforated and adapted to lie approximately in the center of the furnace and rest upon the pipes D, which can be Secured by any suitable means. Upon the opposite side a pipe H extends from the supply-pipe F and passes forward upon one of the grate-bars until the forward portion of the furnace is reached, then Upward, having a perforated extension rearward the height of the wall B, as is shown in Fig. 1, and then extending upward and forward again and resting uponand being supported by means of the dividing-wall I, as shown in Fig. l. These pipes also would form a reversed let- -ter S.
The smoke-stack I have provided between the walls I and the outer walls, and it comprises a large pipe K, which begins approximately on the grate-line of the furnace and centrally within the furnace, as is shown in Fig. 2. It then passes Upward a suitable distance and then outward, where it enters the stach M. The smoke and products of combustion from the fire-pot of course will mingle within the whole furnace, and, passing between the pipes D, E, and H, finally have to settle at the bottom of the furnace in order to be carried out. Upon the side I have, further, a communicating fine N, which extends from the ash-pit 'P into the fire-pot proper above the pipes E, and being provided with a regulating-valve 10. The hot-air chanber C is supported by means of two supporting- IOO bars 5. In front I provide the ash-pit P with the door 7, which can be regulated from without. The smoke-stack M is also provided with a danper, which enters the stack below the pipe K, as is shown. r
Then properly arranged, the operation of my furnace would be as foilows: The fire of course would be built upon the grate-bars 3 and the heat would rarefy and heat the air within the pipes E, part of which air would escape to feed the flames within the fire-pot and the remainder passing upward and escaping at the upper end of the tube E, where it Would mingle with the smoke and thus provide oxygen for the same. The pipe II Would in the same inanner furnish pure air for the flames at the iire-pot, and the rest eX- tending upward and passing along' the wall I immediately above the lower lcg of the pipe K, where this fresh air would further aid in reducing the smoke. The pipe II is led upon the outside for convenience sake into the' supply-pipe F, so thatit gets its supply of fresh air direct from this pipe. Of course it could be led into the cold-air chamber O, but for convenience sake, as stated, this pipe I-I is led directly in the pipe F. In Fig. 2 the forward pipe E, which is also directed into the pipe F, hides the pipe H, as they both lie in the same plane, and in understanding the device the position of the pipe II may be determined in following lines of the pipe E as they enter the pipe F. The air within the tubes D would of course be heated and, passing upward, enter the chamber C, from which it would be conducted through the pipes 12 to the building. A draft through the ash-pit P can be regulated through the door'. Part T he device in its use acts as a smoke-consuming furnace and, as such, a fuel-saving device. To prevent any gas within the furnace from escaping into the building, I do not check its means of escape, but take the draft from it, in that the door 7 can be closed, preventing all access of fresh air to the fire-pot, while at the same time the air is permitted to enter at the valve 9, forming part of the smoke-steel; M, so that the gases will still be permitted to escape out of the pipes K.
Now, having thus described my said invention, what I claim as new, and desire to secure by United States Letters Patent, is-
In a furnace the combination of the following instrumentalities, to wit: a vertical dividing-wall within the furnace dividing the furnace into two eommunicating chambers, one of said chambers being' provided with a horizontal partition, providing -a cold-air chamber, the remaining chamber being provided with a horizontal grate dividing said chamber into an ash-pit and fire-pot, a second Vertical wall extending above said cold- 'air chamber situated between said fire-pot and Vertical diViding-wail the outlet for the products of combustion beingat the bottom of said chamber 'a hot-air chanber within the upper end of said furnace and a system of pipes extending from said upper hot-air chamber and recrossing within the furnace and entering said cold-air chalnber, all substantially as and for the purpose set forth.
In testimony whereof I affiX my signature in presence of two witnesses.
