HARRY H. LINDEMUTH, OF MOUNT JOY, PENNSYLVANIA.
COMBINED STEAM, HOT-WATER, AND HOT-AIR HEATER.
SPECIFICATION forming parl: of Letters Patent No. 373,835, dated November 29, 1887.
Application filed April 4, 1887. Serial No. 233,663.
To aZZ whom it may concern.'
Be it known that I, HARRY H. LINDEMUTH, a citizen of the United Statesresiding at Mount Joy, in the county of Lancaster and State of Pennsylvania, have invented a new and useful Improvement in a Combined Steam, HotWa ter, and Hot-Air Heater, of which the following is a specification.
Myinvention relates to an improvement in a combined steam, hot-water, and hotair heater; and it consists in the peculiar construction and combination of devices, that will be more fully set forth hereinafter, and particularly pointed out in the claims.
In the drawings, Figure l is a vertical sectional view ofaheater embodying my improvements. Fig. 2 is a horizontal sectional view of the same, taken on the line x x of Fig. 1.
A represents an outer vertical cylindrical casing, which is made of boiler-iron or other suitable material. The lower end of this casing is seated upon a ,supporting-case, B, the sides of which converge upwardly. The said supporting-case B forms the ash-pit for the furnace, and is provided with transverse bars C, on which are supported grate-bars D. The bottom of the outer casing, A, isprovided with a central circular opening of suitable size, and
from the said opening rises a vertical cylindrical inner casing, E, which forms thecombustion-chamber of the furnace. The upper side of the combustion-chamber is provided with a central circular opening, F, from which projects a vertical cylindrical neck, G. To the upper end of this neck, and communicating. with the same, is secured a chamber, H, the lower side of which is larger than its upper side. The top of the chamber His formed by a concave or depressed plate, I, having a central opening provided with an upwardly-open ing door, K,
Lrepresents a magazine-drum, which depends from the plate I, extends through the neck G, and enters the upper side of the combustion-chamber. The upper portion of the magazine-drum tapers downwardly, and the lower portion thereof is smaller in diameter.
than the neck G, and thereby an annular space, M, is formed in the said neck, surrounding the lower portion of the magazinedrum.
(No model.)
N represents an annular series of vertical tubes, which connect the upper end of the combustion-chamber with the lower end of the chamber H. By thus providing the furnace with the reduced neck G the draft is sensibly increased, thereby causing more active combustion of the fuel, the area of heating-surface is increased, the iiues N are arranged entirely within the radius of the furnace, and the capacity of the boiler is increased.
O represents a vertical cylindrical case, which is arranged within the outer case, A, at a suitable distance from the sides thereof. The upper end of the interior case, O,.is reduced in size, and has a central opening through which the extreme upper end of the case or chamber Hextends. Thelower end ofthe said case O is also reduced in size, and is connected to an annular vertical collar, P, which is sup` ported upon the cross-bars C, and is arranged in the central opening in the bottom of the outer case, A. A horizontal offset, R, is
formed in the lower portion of the interior.
case, O.
S represents a series of tubes, whlch connect the offset R in the bottom of the interior case, O, with the lower side of the case or chamber H.
By reference to Fig. l it will be noted that an annular chamber, T, is formed between the outer case, A, and the interior case, O, and that the said annular chamber entirely surrounds the said interior case. f
U represents a waterfsupply pipe, which communicates with the annular space or chainber Y, formed between the combustion-chamber and the lower portion of the interior case, O.
W represents an outlet water-pipe, which communicates with said chamber V, as shown in Fig. l. The space between the upper portion of the interior case, O, and the case or chamber H forms a chamber, X.
Yrepresents a steam-circulating pipe,which is connected to and communicates with the upper portion of the interior-case, O, and extends through the upper end of the outer case, A,
Z represents an annular case, which is arranged in the lower end of the outer case, A,
and at a slight distance from the same, thereby forming an inlet air-chamber, a, between the said outer case, A, and the annular case Z.
Z) represents openings which are made in the lower portion of the case A. On one side of the latter is arranged a water-gage, c, having a pipe, d,whieh communicates with thelower end of the chamber V, and a pipe. e, which communicates with the upper end of the chamber X. In the said pipe e is arranged a steampressure gage,f, and communicating with the said pipe is a safety-valve. g.
The upper end of the outer case, A, has a central opening, l1., communicating with an escape pipe or iue, i.
The operation of my invention is as follows: Tater is admitted to the chamber V between the interior case,O,and the combustion-chamber, and surrounding the tubesNand S. Fire is startedin the combustion-el1amber, and the magazine-drum L is filled with coal to replenish the tire automatically from time to time. Air which enters the annular chamber b through the openings c rises into the annular chamber T, surrounding the case O, and becomes heated by contact therewith and by the radiation therefrom. The space X in the upper portion of the interior case, O, forms a steam-chamber, and the steam escapes from thence through the pipe Y into the steam coils or radiators (not shown) in different parts of the building. The water-pipe \V may be connected with suitable water-circulation pipes, (not shown,) in which a constant circulation of hot water from the chamber V can be maintained by a pump or other suitable device, if desired. rIhe smoke and products of combustion pass upwardly from the combustion-chamber through the tubes N into the chamber H, thereby heating the latter and causing the same to superheat the steam in the steam-chamber X, and from the hot-air chamber H the smoke and products of combustion pass downward through the inclined tubes and through the bottom ofthe inner case, O, into the lower portion of the outer case, A. As the smoke and products of combustion pass upward through the annular space or chamber 'Il between the outer case, A, and the iuterior case, O, they become mingled with the air in the said space or chamber and assist in heating the same. The apartment in which the heater is located is heated by the radiation of heat from the outer case, A.
rlhe lower portion of the outer case, A, is provided with openings or man-holes 7c, which are covered by the movable plates Z. These man-holes enable access to be obtained to the interior ofthe space or chamber T, so that the soot may be removed therefrom from time to time.
OZ represents a curved shield, which is secured to the inner side of the boiler, covers the inner end of theinlet-pipe U, and extends downward into the boiler a suitable distance below the water-line, the function of this shield being to prevent the inner end of the pipe Ufrom becoming uncovered when the waterin the boiler is low.
Havlng thus described my invention, I claim- 1. The furnace comprising the combustionchamber E, the reduced vertical neck G, the enlarged case or chamber H at the upper end of the neck and communicating therewith, the tubes N, surrounding the neck and communicating with the combustion-chamber and the case H, and the fines S, in combination with the magazine-drum L, depending from the upper side of the case H and extending through the neck G and out of contact therewith, and the steam-boiler surrounding the furnace, the case H ofthe latter being wholly within the steam-space of the boiler, substantially as described.
2. The combination of theinterior furnace, the boiler surrounding the same, the escapeiiues extending from the furnace downwardly through the bottom of the boiler, the hot-air ease A, enveloping the boiler and arranged at a distance therefrom, thereby forming a space through which the products of combustion pass, the said case A having the openings a, and the case Z, arranged on the inner side of the case A at a distance therefrom, thereby forming an inlet annular chamber, I), to supply cold air to the case A, substantially as described.
3. The lcombination of the interior furnace, the boiler surrounding the same, the escapeiiues extending from the furnace through the boiler, the water-circulating pipes communieating with the water-chamber of the boiler, the steam-pipe communicating with the npper portion of the boiler, and the surrounding outer ease, A, enveloping the boiler and thereby forming a space around the same, the escape-fines ofthe furnace communicating with the said space, substantially as described.
4. The combination of the furnace, comprising.,r the combustion -chamber E, the reduced vertical neck G, the enlarged case or chamber H at the upper end of the neck and communicating therewith, and the vertical flues N, connecting the combustion-chamber and case H, said iues surrounding the necks G, the boiler entirely enveloping the furnace, the tlues S, extending from the bottom of the case H through the bottom of the boiler, the water inlet and outlet pipes communicating with the boiler, the depending shield O2, covering the inner end of the inlet-pipe and eX- tending down in the boiler, and the case A, enveloping the boiler, substantially as described.
