UNITED STATES PATENT JOHN \V. CLARK, OF UTIOA, NEW YORK.
H EATlNG-FURNACE.
SPECIFICATION forming part of Letters Patent No. 379,364, dated March 13, 1888.
Application filed July 2, 1887. Serial l\"o. 243,226. (No model.)
To aZZ whom it may concern:
Be it known that I, JOHN WV. CLARK, of the city of Utica, in the county of Oneida and State of New York, have invented certain new and useful" Improvements in Heating-Furnaces; and I do hereby declare that the following is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawing, and to the figures of reference marked thereon, which forms part of this specification.
My invention relates to an improvement in heating or hot-air furnaces; and it consists, principally, in surrounding the fire-pot and combustion dome of the furnace with an encircling radiator of peculiar construction, as will be hereinafter described and set forth.
Referring to the drawing, the figure represents in perspective a vertical section of my improved furnace, in which 1 represents the walls of the ordinary ashpit, firebox, and combustiondome.
2 represents the encircling and surrounding radiator.
3 represents an encircling and surrounding smoke-flue, which is of approximately thesame (liamator as radiator 2. This is located above the radiator and is connected therewith by pipes 4. Located at any convenient point on flue 3 is a smoke exit pipe or collar, 5. The upper portion of combustiondome 1 is provided with an aperture, 6, to which is connected the vertical pipe 7. This pipe connects with a horizontal crosspipe, 8, which connects at each end with fine 3. Vertical pipe 7 is provided with an ordinary damper, 9, which is actuated by handle 10. The dotted lines 11 represent the ordinary metallic casing of a furnace, although brick or stone may be used in place of it if desired.
12 represents the ordinary hot-air pipesv connected with and leading from casing 11.
13 represents the ordinary feed-opening into the furnace, which can be closed by door or .other means.
14 and 15 represent air-passages leading be neath the grate 16, the functions of which will be described later on.
Reference to the drawing will show that the radiator 2 is provided with a series of vertical diaphragms, 17. These diaphragins are continuous with the walls of the radiator, except at the bottom, where they are shortened sufficiently to leave a passage between their lower ends and the bottom wall of the radiator, as shown at 18. Air-passages 14 and 15 are closed at their outer ends by doors, dampers, or any other known method and are designed to operate as follows: In the normal operative condition of the furnace passage 11 is closed and the supply of air for supporting combustion is admitted through passage 15. At certain times the heat radiated by the furnace may be in excess of the requirements. In such case passage 15 is closed and passage 14 opened. By this means the current of inflowing air absorbs heat from the air in the interior of the furnace-casing, resulting in lowering its temperature and at the same time raising the temperature of the inflowing aircurrent. This has, in a measure, the effect-0f a hot blast and results in economy in the use of fuel.
The operation of my furnace is as follows: Fire is kindled in' the fire-pot and the damper 9 opened, so that the products of combustion pass directly up pipe 7, thence horizontally through pipe 8 and into flue3, and from thence to the smoke-exit 5. This arrangementforms what I call a direct-draft furnace. After the fuel is well ignited, I close damper 9,when the products of combustion are forced to pass through pipes 20, thence into radiator 2 and down on one side of diaphragm 17, and under the lower end of the same and up on the other side, thence to pipes 4 and through them to due 3, and thenceto smoke-exit 5. This I term the indirect-draft furnace.
19 represents holes in the base-plate of the furnace for the admission of the air that is subsequently heated and conveyed off through the air-pipe 12.
21 represents a standard that supports the radiator 2. I provide as many of these standards as the weight and size of the radiator may require. Proper cleaning-apertures are provided in the furnace wherever required, and any ordinary grate can be used in connection therewith.
It will be readily perceived that a furnace chimney.
of the construction described affords a large tor substantially encircling the fire-pot and amount of radiating-surface and causes the products of combustion to travel a comparatively long distance in contact with the radiating-surface before they are discharged into the Changes in construction would readily suggest themselves to one skilled in the art to which myinvention pertains,which changes could be made without departure from the central feature or spirit of my invention; hence I do not limit or confine myselfto the precise specific construction hereinbefore described and set forth.
\Vhat I claim as new, and desire to secure by Letters Patent, is-
The combination,with a furnace, of a radiacombustioudome of the furnace, having diaphragm plates dividing the radiator into spaces connected at the bottom, a superposed drum, a series of dues connecting the furnacedome with the alternate spaces of the radiator, and a series of dues connecting the remaining spaces of the radiator with the superposed drum, substantially as set forth.
In witness whereof I have affixed my signature in presence of two witnesses.
JOHN T. CLARK.
