` Specification of Letters Patent.
Patented Aug. 5, 1919.
Application led December 10, 1917.l Serial No. 206,446".4 j
To all whom 'it may concern.' y 4 i Be it known that I, ABRAHAM MILEY IAMs, a citizen of the United States 1of America, and a resident of Gary, county of Lake, and State of Indiana, have invented certain new and useful Improvements in Furnaces, ofwhichthe followingfisa speciiication.
A number of different types of furnaces now in general use are placed upon the market wit out provision for a secondary air supply to the gases rising from the fuel. Accordingly, in order to render such furnaces smokeless and more efficient, appliances have been provided for supplying preheated air in the fireboX above the fuel. The present invention relates to a simplified construction for the purpose of heating a secondary air supply and uniformly distributing it above the fuel.
Objects of the invention are to provide such means so designed as to be easily attached to ordinary furnaces and to make parts of said attachment removable so that the burned-out parts may be easily replaced at small expense.
An illustrative embodiment of the invention is shown in the accompanying drawings, in which- Figure 1 is a front elevation of a furnace provided with the present improvements.
Fig. 2 is a longitudinal vertical section partly broken away, taken on the line 2-2 of Fig. 1.
The drawings show a furnace in general of well known construction, having the usual masonry 1 surrounding a fire-box 2.
The present improvements comprise a plurality of conduits 3 which are closed at their rear ends 4 and are provided with hinged doors 5 at their forward ends. A solid support 6 which may rest in one of the flues 7 is rigidly secured to the rear end of each of the conduits 3. Each of the conduits 3 has a plurality of depending nipples 9 to which are secured vertical branch pipes 10 by means of pins 11 fastened through the upper ends of the branch pipes and the nipples 9. In assembling the improved structure in the furnace, the conduits 3 are passed through the firing doors, the supports 6 being caused to enter the flues which are in line with the respective circular apertures 12 cut in the front wall 13 of the furnace. The conduits 3 are then moved forward so that their forward ends project .through the Aapertures 12 and are accordingly supported at such points and atk the lues by the supports 6. The branch pipes 10 areth'en'pinnsfl to the nipples 9. lTwo yof the conduits ,3each having two depending outlet pipes positioned as shown, give satisfactor-y` resultsyby providing a fairly uniform -vdlstribution of the air over the body of the fuel. Since the fuel has a tendency to burn away more rapidly at regions adjacent the outlets of the air heating device, the pipes 10 are preferably located approximately half-way between the center of the furnace and the surrounding walls. This results in fairly uniform combustion taking place throughout the entire grate area.
The intensity of combustion is automatically regulated by pressure controlled means having connections for opening and closing the hinged doors 5. For this purpose, the motor 14. which communicates with the interior of the boiler through the pipe 15 is arranged to oscillate the lever 16 according to changes in pressure occurring in the boiler. The lever 16 is pivotally supported at 17 and has a pivotal connection 18 with the piston or diaphragm of the motor. Its outer end is connected with the doors 5 by chains 19 and 20 passing over the pulleys 21. On a certain predetermmed increase in pressure, the lever is swung upwardly on its pivot 17, thus roviding slack in the chains 19 and 20 and) permitting the doors 5 to move toward their closed position by gravity. A fall in pressure causes the doors to open.
In the operation of the device, the draft of the furnace causes air to be drawn inwardly through the conduits 3. It becomes heated through contact with the walls of these conduits and the walls of the vertical pipes 10. Due to the fact that the pipes 10 are properly spaced with respect t0 each other and the side walls and the center of the furnace, fairly uniform distribution of the secondary air supply is obtained. This results in increased efliciency of combustion and fuel economy and involves but slight addition to the furnace, requiring little labor to install and no material change in the construction of the furnace itself. The pipes 10 are to a large extent prevented from burning out by the air passing through them, and this air is in turn heated by contact with the walls of the pipes. If the lower ends of the pipes become considerably burned after long service, they may be easily replaced simply by removing the pins 11.Av
