COMBINED HOT AIR AND WATER HEATER.
SPECIFICATION forming part of Letters Patent N 0. 780,587, dated January 24, 1905. Application filed April 14, 1904. Serial No. 203,130.
Ohio, have invented certain new and useful Improvements in a Combined Hot-Air and Hot-Water Heater; and I do hereby declare the following to be a full, clear, and 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 accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.
My invention relates to heating apparatus of the class adapted for combined hot-air-radiating and water-heating purposes, and has for its object to provide a heating apparatus of this class that is so constructed as to enable the heat units generated by the fire to be equally utilized for heating both air and water or to have their course so directed as to increase the air-heating efliciency of said apparatus without a proportional increase in the heating of the water circulating therethrough.
My invention is fully described in the following specification and shown in the accompanying drawings, in which Figure 1 is a central vertical section of a furnace comprising my invention, taken on the dotted lines D D in Fig. 4. Fig. 2 is a similar View taken on the dotted lines A A and E E in Figs. 1 and 3, respectively. Fig. 3 is a cross-section thereof, taken on the dotted line B B in Fig. 2; and Fig. 4 is a similar view taken on the dotted line C C in Fig. 2 and eliminating the base.
Referring to the drawings, 1 represents the base; 2, the ash-pit, which has the draft-door 2 provided therein; 3, the fire-pot or combustion-chamber; 4, the radiator, which encircles a greater portion of the combustionchamber, and 5 the outer casing of a furnace of the hot-air type.
Suspended within the combustion-chamber 3 by any suitable means is a tapered fuelmagazine 6, which, with the exception of the under side thereof, is entirely surrounded by a water-chamber 7, the said chamber forming a water-leg around the vertical surface of the magazine. A fuel-feed opening 8, having its outer end closed by a door 8, leads from the exterior of the casing 5 to the upper portion of said magazine. Water is fed to the chamber 7 through the inlet-pipe 9, which communicates at the rear with the lower portion of said chamber and is expelled therefrom through the outlet-pipe 10, which communicates therewith at a point above the feed-door 8, as shown in Fig. 1.
A casting 11 is mounted above the magazine 6 and forms the smoke-chamber 12, which is entirely separated from the combustion-chamber 3 by the expanded upper end of said magazine, except as herein described. Leading transversely from the chamber 12 are the two horizontal fiues 13, which communicate with the radiator 4, at either side thereof, through the openings 14:, provided in its upper casing 15. Removable caps 16 are pro vided in the outer ends of the flues 13 to enable said fines and the chambers 12 to be a other products of combustion through the flues 16 and 17 to the horizontal fhi'es 13 is controlled by a pair of dampers 18, which are hinged adjacent to and adapted when in a horizontal position to close the upper ends of the flues 17 thereby causing all of such products to find an exit from the combustion-chamber through the fines 16. A double seat is provided within the chamber 12 for each of said dampers 18, one seat being at the upper end .of the fines 17, as above described, and the other disposed diagonally of the mouths of the horizontal fines 13,leading from said chamber,
thus enabling said dampers when opened to their fullest extent to close off the portion of the chamber 12 into which the fines 16 enter, as shown by dotted lines in Fig. 2, and to cause all of the products of combustion to be expelled to the radiator from the combustionchamber through the direct fines 17.
The dampers 18 are regulated from without the furnace by means of the rod 19, the turning of which oscillates the member 20, fulcrumed within the chamber 12, and causes a desired movement of said dampers,which latter are connected with said oscillatory member by means of the links 21.
Partitions 22 are provided in the radiator 4 at the rear of the inlet-openings 14 for the purpose of causing the products of combustion to twice traverse the length of the radiator before finding an exit through the smokepipe 23.
As gases frequently accumulate in the upper portion of the magazine-chamber, especially when soft coal is burned, I have provided a gas-exit pipe 24; within the casing of the magazine, the said pipe having one end communicating with the upper part of the magazine-chamber and its other end opening into the combustion-chamber. In order to cause a free circulation in the upper portion of the magazine-chamber and prevent stagnation of the gases therein, an air-circulation pipe 25 is'provided, which opens communication between the ash-pit 2 and the feed-opening 8.
In the operation of my heating apparatus water is caused to freely circulate around the fuel-magazine within the chamber 7 and to become highly heated by reason of the flame and products of combustion passing through the fines 16 and 17 and also coming in contact with the exposed outer surface of said magazine. Should the water become too hot or it be desired to increase the heat-radiating efficiency of the stove or furnace without nnnec essarily boiling or heating the water within the chamber 7 to a high temperature, the dampers 18 are thrown up to the position shown by dotted lines in Fig. 2, thereby closing the outlets from the chamber 12 to the fines 13 and causing all of the products of combustion to be directed through the side fines 17 directly to the radiator 4.
While my invention is shown in the drawings as being embodied in a furnace, it is obvions that the same may be employed in any form of magazine-stoves and that such changes in the form, proportion, and minor details of construction of the parts as fairly fall within the scope of my invention may be made without departing from the spirit or sacrificing any of the advantages thereof.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent. is-
1. In a heating apparatus, a combustionchamber, an exit-fine, afnel-magazine, a water-chamber associated with said magazine, two series of fines passing through said waterchamber and communicating at one end with the combustion-chamber and at the other end with the exit-fine, one of said sets of lines having more water-heating surface than the other, and means for controlling the passage of products of combustion through said fines.
2. In a heating apparatus, a combustionchamber, an exit-fine, a fuel-magazine, a water-leg surrounding said magazine, two series of fines passing through said water-leg and communicating at one end with the combustion-chamber and at the other end with the exit-fine, one of said sets of lines having less water-heating surface than the other, and dampers controlling the mouths of said fines adapted to be moved to cause the smoke to be directed through one or the other of said sets of fines or both.
3. In a heating apparatus, the combination of a combustion-chamber, a magazine, an ashpit, a conduit for directing the gases confined in the upper part of the magazine to the combustion-chamber, and a second conduit leading from the ash-pit to the upper part of the magazine for the purpose described.
4. In a heating apparatus, a combustionchamber, a fuel-magazine having a surrounding Water-jacket, a smoke-chamber above said magazine, a radiator, fines connecting said chamber and radiator, two series of fines extending through said water-jacket and communicating with said chamber from the combustion-chamber, and dampers adapted when closed to directthe products of combustion to said radiator from one set of said fines and when fully opened to direct said products through the other set of said fines.
5. In a heating apparatus, a fuel-magazine having a surrounding water-jacket, a smokechamber above said magazine, a smoke-exit, a combustion-chamber, fines leading from the smoke chamber and having communication with the smoke-exit, direct and indirect fines passing through the water-jacket for conducting the products of combustion from the combustion-chamber to the months of the smelteexit fines in said smoke-chamber, and means within the smoke-chamber for directing the products of combustion through one or the other of said direct or indirect fines or both.
In testimony whereof I have hereunto signed my name to this specification in the presence of two subscribing witnesses.
