IMPROVEMENT IN HOT-AIR FURNACES.
Specification forming part of Letters Patent N 0. 134,879, dated January 14, 1873.
To all whom. it may concern:
Be it known that I, WILLIAM B. GEDDEs, of Rochester, in the county of Monroe and in the State of New York, have invented certain new and useful Improvements in Heaters of Furnaces; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon making a part of this'specification.
The nature of my invention consists in the construction and arrangement of a heater or furnace, as will be hereinafter more fully set forth. 7
In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in which- Figure 1 is a longitudinal vertical section of my furnace or heater; Fig. 2 is a horizontal section of the same through line w an, Fig. 1; Fig. 3 is an enlarged perspective view of a part of the interior of the heater; and Fig.
4 is a perspective view of one of the water tanks or reservoirs used in the same.
A represents the bottom plate, and B the outside shell of my furnace. G is the fire-box, with the ash-pit D underneath. Ontop of the fire-box O is a conical cap or cover, E, with apertures afor the passage of the smoke, 850., upward. This cone extends up into a cylinder, G, which rests upon a bottom-plate, I), attached to the cone. Surrounding the cylinder G is another cylinder, H, which rests upon the inner edge of an annular plate, d,
attached to the inside of the shell B and on a line with the plate I), leaving an opening, 6, between said plates for the passage of the products of combustion between the two cylinders. The interior of the inner cylinder G is connected with the exterior of the outer cylinder Hby means of radiating flues-I I, which are inclined upward and outward, as shown in Fig. 1. From the base of the cone E to the interior circumference of the plate at extends an inverted cone, E, which conducts the heat and smoke from the apertures a in the cone E to the opening 6 leading to the space between the two cylinders G'and H. Through the space thus inclosed between the two cones E and E are inclosed passages f leading from the outside of the outer cone E to and through the plate I), so as to communicate with the interior of the inside cylinder G. J represents a water tank or reservoir, from which the steam is allowed to pass into a pipe,
K, leading from the outside of the furnace to a ring,- L, surrounding the fire-box at the base of the cone and communicating with the interior of the fire-box by means of hollow arms or short pipes 'i t. J represents another water tank or reservoir, from which the steam is allowed to pass into the ash-pit D, and thence through the grate into the fire-box C. The upper end of the interior cylinder G is closed by an inverted cone, E", and from the upper end of the same outward is an annular plate, It, extending to the outer shell B. This plate h is, between the outer shell and the cylinder H, perforated with any suitable number and size of apertures i to allow the air heated in the furnace to pass upward into the cap M which covers the whole furnace, and from thence through apertures To escape into the room, or by pipes be conducted to the place where needed. From the space between the two cylinders G and H, small pipes 70 7t conduct the smoke into a circular pipe, N, within the cap M, and from thence it passes through a pipe, 0, into the chimney. Opposite this pipe, in the circular pipe N, is another pipe, P, with damper or register on the end to regulate the draft. R is the passage for the introduction of the fuel into the fire-box (J. S is a partition extending from the plate d upward between the cylinder H and shell B to near the plate h.
The cold air, entering the base of the heater or furnace becomes rarefied and passes up into the interior cylinder G, and passes out through the radiating-fines I I, which are inclin' ed upward, as shown, thereby increasing the rapidity of the passage of the heated air from the inside to the outside chamber, from whence it passes upward into the cap or dome M and discharges into the rooms.
By this improvement I am enabled to pass about one-half more cold air over the heatingsurface in the same space of time than can be done with the usual form of heater and fines, and consequently producing a more healthy atmosphere from the fact that there is much her serves a double purpose less oxygen consumed in passing over the heatingsurface so rapidly than there is in a slow passage over the same. The radial flues being elevated or inclined sc cures this s peedy current, as when the air becomes heated it expands and forces itself more rapidly through the same than it would'in concentrating it in the center and discharging it in a solid body.
The ring L, with arms or apertures t' "5 surrounding the top of the fire-pot 0, admits cold air combined with steam from the tank J, or steam alone, if desired, for the purpose of consuming the gases and the products of combustion. The gases which escape ignition in risingrpass' up into'the cone E above the fire,
and then'deflect downward and again come in contact with the steam and air passing inward through the ring L, and are then ignited and consumed before passing into the combustion-chamber or fiuespace, thus producing a greater amount of heat than could otherwise be obtained from a given amount of fuel without the use of steam over the fire.
The steam from the water-tank J passes up through the grate to aid the combustion.
The cone E in the top of the center chamas a water-pan for heating water to make steam to moisten the hot air, and also to divide the hot air in the chamber and press the said air out through the flues equally all around. The water may be admitted to this pan through a pipe which opens at the outside casing and extends inward, discharging into the pan, as shown in Fig. 1 by dotted lines.
Having thus fully described my invention,
forming a communication between the interior and exterior chambers of a heater or furnace, substantially as and for the purposes herein set forth.
' 3. The" interior heating chamber'G having inlets at the bottom, closed at the top, and radiating elevated flues I I to conduct the heated, air from the same, substantially as and for the purposes herein set forth.
4. The combination of the interior heatingchamber Gr, inclined flues I I, and the top cone E substantially as and for the purposes herein set forth.
5. The heater or furnace composed'of the shell B, fire-pot O, cones E, E and E cylinders G H, inclined flues I I, tanks J J ,'ring L, dome M, and chamber N with pipes O I, all constructed and arranged substantially as and for the purposes herein set forth.
In testimony that I claim the foregoing I have hereunto set my hand this 3d day of September, 1872.
