UNITED STATES PATENT OFFICE.
CHARLES M. RYDER, OF NEW YORK, N. Y;
REG EN ERATIVE QGAS-FU RNACE.
SPECIFICATION forming part of Letters Patent No. 416,753, dated December 10, 1889.
Application filed August 18, 1888. Serial No. 282,548. (No model.) i
To aZZ whom, it may concern:
Be it known that I, CHARLES M. RYDER, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Regenerative Gas-Furnaces; and I do declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, which form a part of this specification.
My invention relates to an improvementin reversing regenerating-furnaces, the object being to secure an economy of fuel and of space, labor, and material in establishing a plant.
Withthese ends in view my invention consists in locating the regenerating-chambers and the reversing valve directly over the combustion-chamber of the furnace, in providing gas-heating fines for utilizing the heat radiated from the bottom of such chamber in heating the gas before it is burned, and in making provision for facilitating the disposal of any cinder which may accidentally enter the gas-heating fines.
In the accompanying drawings, Figure l is I a View in vertical longitudinal section of a furnace embodying my invention, one of the regenerating-chambers being shown empty of checker-brick. Fig. 2 is a horizontal sectional view thereof, taken on the line a: a: of Fig. 1, and showing the fines under the combustion-chamber by broken lines. Fig. 3 is a transverse sectional view "of the furnace on the liney y of Fig. 1. Fig. 4 is a broken plan View showing the central part of the furnace; and Fig. 5 is a View of the furnace in vertical transverse section on the line z z of Fig. 1, and looking toward the combustionchamber.
An ordinary reversing Valve A of the flap type is mounted in a valve-shell B, located centrally over the combustion-chamber C, and having side openings respectively leading into regenerating-chambers D and E, of which the latter is shown to be filled with checker-brick S, while the former is empty of them. The said shell rests upon the floors F F of such chambers, which are in turn supported upon transverse beams G G, the opposite ends whereof bear upon angle-plates H H, secured to the inner faces of plates I I, which close the front and rear ends of an airhorizontal supply-pipe N located back of the furnace. The upper end of the said valve- ;shell opens into the draft-fine O, as shown.
The valve A is mounted upon a horizontal shaft P, extending rearward, and provided at its outer end with a short arm Q, having con- I tached at its lower end to the manual S,secured to the projecting end of the rock-shaft nected with its outer end a long lever B, at-
T of the rock-arm U, which is located within the reversing gas-valve chamber'V and flexibly connected with a sliding gas-valve W, as
shown. A gas-supply conduit X leads into the said chamber V, the lower or bottom wallwhereof is furnished with two port's Y and Z,
respectively leading into forwardly inelined gas-fines A and B, located .nndenthe combustion-chamber of the furnace and extending back to the front of the furnace.
A series of inclined parallel gas-flnes Ci lead upward from the fine A and underft'h'e' combnstioirchamberto one end of the'fur-' nace, where they intersect and open into a' transverse gas-receiving flue D, from theopposite ends whereof passages E E, formed in the corners of the furnace structure, lead upward and open into the lower end of an airflue F, formed between the adjacent end wall G of the furnace structure and the wall L next to the same, and opening at its upper end into the regenerating-chamber D and at its lower end into the combustion-chamber. A series of gas-fines I-I', corresponding to the fines 0', lead from the flue B to the opposite end of the furnace, where they all open into a fine 1, corresponding to the flue D, and provided with corner passages J J, opening at their upper ends into the lower end of the air-flue K, formed between the opposite end wall G of the furnace-structure and the wall Ladjacent thereto, and opening at its upper end into the regenerating-chamber E and at its lower end into the opposite end of the combnstion-chamber. The said fines A, B, C, and H are roofed with tile brick L, above which the sand bottom M of the combustionchamber islaid. The said bottom of the chamber slopes away from its front end and is provided with two cinder-collecting depressions N N, each having a tap-hole through which, under ordinary circumstances, the cinder is discharged for collecting in pits or cars. Tap-holes P P lead from the forward ends of the main fines A and B into a cinder-pit R, as shown.
Having described my improved furnace in detail, I will now set forth the mode of its operation.
Air being forced into the air-conduit passes the flap-valve, according to the position of the same. When the valve is in the position in which it is represented by Fig. 1 of the drawings, this hot air passes into the chamber D, and is still further heated, and now intensely, by the absorption of heat from the checker-brick with which it is filled, although they are not shown herein. Passing through this chamber, the air will enter the fine F, in the lower end whereof it will be mingled with gas delivered thereto by the fines E, D, G, and A, which are intensely heated-by heat radiated from the bottom of the furnace. The heated air and heated gas, commingling, will now enter the combustion-chamber and burn there. The Waste products of combustion pass to the opposite end of the said chamber, out into the fine K, and thence into the regenerating-chamber E, where the heat in them will be taken up, and then through the shell B and into the draft-fine. The flap valve is now reversed, and the same operation will be repeated in reverse direction. As occasion demands, the upper tap-holes will be opened to 'permit'the cinder to escape and flow into ordinary cinder pits or cars for removal. The fines under the combustionchamber are inclined, so that in case the cinder escapes accidentally through the bottom of the combustion-chamber it will gravitate into the cinder-pit R, whence it may be removed without delaying the operation of the furnace.
It will be apparent that by suspending the regenerating-chambers and reversing fiapvalve over the combustion-chamber, instead of locating them at one side of the same, as now practiced, an economy of space is 110t- "only effected, but also an economy of material and labor in building the plant. It will be apparent, also, that an economy of fuel will resultflO-ul employing the heat radiated from the bottom of the combustion-chamber and now lost to heat the gas. The provision for handling the cinder and slag is labor-saving and facilitates the operation and care of the furnace.
I would have it understood that I do not broadly claim as my invention the formation of an air-heating chamber over the combustion chamber, that being the invention of another. I would also have it understood that I do not limit myself to the exact construction and arrangement of parts herein shown and described, but hold myself at liberty to make such changes and alterations as fairly fall withih the spirit and scope of my invention.
Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. In a reversing regenerating gas-furnace, the combination, with a combustion-chamber, of regenerating-chambers located over the combnstion-chamber, fines leading from the opposite ends of the combustion-chamber to the upper ends of the regenerating-chambers, a reversing valve located between the regenerating-chambers and near the fioors thereof, a casing for such valve opening directly into each of such chambers, a hot-air conduit leading to the lower end of such casing, and a draft or chimney fine connected with the upper end of the casing and extending out between the regenerating-chambers, substantially as set forth.
2. In a reversing regenerating gas-furnace, the combination, with the combustion-chain ber thereof, of a series of gas-heating fines located under such chamber and heated by the radiation of heat therefrom and inclined so as to free themselves of any cinder which may accidentally enter them through the bottom of the combnstion-chamber, a gassupply connected with these fines, and fines for taking the superheated gas from the gasheating fines and conducting it to the combnstion-chamber, where it is combined with heated air, substantially as set forth.
3. In a reversing regenerating-furnace, the combination, with a combustion-chamber, of two regencrating-chambers and a reversing valve suspended over the same, a series of gas-heating fines located under the com bnstion-chamber and heated therefrom, two gas-receiving fines, respectively located at the ends of the furnace and intersected by such gas-heating fines, and two 'air-finesleading from the regenerating-chambers to the opposite ends of the combustion-chamber and intersected at their lower ends by passages leading from the gas -receiving fines, substantially as set forth.
In testimony whereof I have signed this specification in the presence of two subscribing witnesses. I
CHARLES M. RYDER.
