@uitrit taies @anni @frn DEVICE FOR VENTILA'IING AND HEATING ROOMS.

TO ALL WHOM IT MAY CONCERN:

`Be it known that I, JAMES H. Looms, of Attica, in the county of Wyoming, .and State of New York, have' invented a new and improved Method of Warming and Ventilating Rooms and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, in which Figure 1 is a view of the apparatus which I employ, applied to use in warming an apartment separate from that iu which the heater is situated, the heater being shown in central vertical section.

Figure 2 is a transverse section on the linex rc of fig. 1.

Like letters indicate corresponding parts in both figures.

My invention consists in the combination and arrangement, with a drum-heater of a stove pipo, of conducting pipes, which take the cold air from an adjoining space or apartment, and after heating it by contact with the radiating surface of the heater, returning the warm air to the room from which it was taken; and thus, by a continuous circulation of the air from another room, utilizing the heat which would be wasted by escaping' throughthe smokerpipe with the products of combustion;` and also, in so constructing the heater, that the' cold air introduced is diffused and compelled to circulate in immediate contact with the heated surface of the smokeilues. As represented in the drawings, A is an ordinary stove for heating an apartment, with the smoke pipe' of which is connected a drum-heater, B. This heater is preferably constructed with a series of tubular tlues, d d, connected at their upper and lower ends with diaphragms c c', which exclude the products of combustion from entering the space around the tlues, and compel them to pass through them, they being open at the bottom, and only partially closed at the top by the perforated conical caps e e, for arresting sparks and cinders. This arrangementksecures a large amount of heating surface for thc air within the drum B, which circulates in contact with the heated fines and I secure a more eifectual circulation and better result by means of another diaphragm,. f, placed immediately above the point where cold air is admitted by the air pipe G. This diaphragm is provided with an annular series of perfor-ations, z' z', close around the lues d, (as shown most clearly in g. 2.) Cold air' admitted through pipe G, lls the space below f, and, as it becomes warmed, rises through the porforations t' t', its only mode of egress. `These perforations being arranged close around the ilucs, cause all the air to pass inv small jets or currents over these heated surfaces, from which they rapidly absorb caloric. The pipe G leads from a register, g, which may be placed in or near the loor of the room to be warmed, at any convenient place, so that the air 'which it supplies comes from the coldest portion. As this is rarced by the heat it acquires in passing through the drum, it is conducted out by the pipe H, which re-enters the apartment at any convenient point, discharging the warm air through a register. The'warm air rises and circulates through the upper portion of the room, until suiciently cooled to descend to the floor, when it is again drawn through the lloor register into the pipe G. In this mannera continuous circulation of the air within another room through the partition or wall into the heater, andl back again to the room from whence it came, is maintained, utilizing the heat escaping by the pipe of the stove, muchof which would otherwise be lost. When rooms are closed in cold weather, the only fresh air supplied is that which filters through the window and door crevices, which; being colder, accumulates at the lower part ofthe room, displacing the warmer and lighter air. This is attended with discomfort and productive of disease, from .the constant coldness to which thefcct of the occupants are subjected. By my method of warming, the fresh and cold air which enters is, by the circulation which is-constantly taking place through pipes G and H, at once drawn through the lloor register` t, passed through the heater, and discharged again through I-l,y thus warming the freshly introduced air, and distributing it throughout the room. In this manner. my system acts as effectively-in Ventilating as in `warming, keeping the air much `more pure and wholesome than that of a closed room warmed by the direct radiation of the heat of a stove, as in the latterv case there is no system of circulation established, and the air nearest the stove andy highest in the room growsl hotter and more vitiated continually, and the cold air remains comparatively undisturbed in the lowest-and remote parts of the room. The air which is supplied by my method is better adapted for breathing than that of ordinary hotair furnaces, when it is warmed in contact with parts so highly heated as to deprive it of its vital properties to a great extent. The air is made tol pass so rapidly, and is so perfectly diffused overall of the conducting surfaces of my heater, that no part becomes heated to excess, and thc air which it causes to circulate in other apartments is tempered to a mild and genial degree of warmth. The pipes and registers may be multiplied on this principle to any extent desired. The obvious advantages resulting from it are economy of fuel where stoves are used, and purer and more wholesome air in rooms so warmed. I also introduce in the upper partition c, a damper, o, which when opened by drawing out the handle 1t, allows the air introduced by pipe Gr to pass into the smoke pipe, and thereby ventilate the room warmed by the circuit through pipes G H, by carrying off vitiated air, and especially the carbonio acid gas, when, by cooling, the latter descends to the floor. Opening this damper also diminishes the draught of the stove A, thus serving the double purpose of a. ventilator and hre-regulator.

lVhat I claim as my invention, is-

The pipes G H, in combination with the stove-pipe heater B, constructed as' described, for conveying cold air from and returning Warm air to another apartment, arranged and operating substantially as set forth.

I also claim constructing the heater B, with the diaphragmf, provided with the annular vperforations z' z', around the ilues d, substantially in the manner and for the purpose described.

I also claim the damper n 0, in combination with the drum-heater B, air-induction pipe G, and stove A, arranged and operating substantially as and for the purposes set forth.

.In Witness )thereof I have hereunto signed my naine in the presence of two subscribing witnesses.
