APPARATUS FOR HEATING BUILDINGS.

Specification of Letters Patent No. 24,590, dated June 28, 1859.

To all whom it may concern:

Be it known that I, GEORGE S. G. SPENCE, of Boston, in the county of Suffolk and State of Massachusetts, have invented an Improved Apparatus for Heating Buildings by Hot \Vater and Steam as Auxiliary Thereto; and I do hereby declare that the same is fully described and represented in the following specification and the accompanying drawings, of which Figure 1, is a top view; Fig. 2, a front elevation; Fig. 8, a side elevation; Fig. 4, a horizontal section, Fig. 5, a vertical and transverse section and, Fig. 6, a vertical and longitudinal section of it.

The nature of the invention consists in the peculiar form of the boiler; first, having a large horizontal surface below to receive heat from the fuel chamber, and on its upper surface to discharge into the discharge hot air pipe; second, having in its vertical part an internal and external radiating surface for heating the cold air passing over the same.

In such drawings, A, denotes the outer case, which may be constructed of metal or brickwork and so as to form a chamber, B, for the reception of the air and heat radiating apparatus to be hereinafter described.

A boiler, C, with its fire place, D, and ash pit, E, are arranged within the chamber, B, as shown in the drawings, particularly in Figs. 5 and 6, thereof, the external surface of the fire-place and the smoke chamber, E, as well as that of the smoke discharge pipe F, being so arranged as to radiate heat into the chamber, B, while the boiler is heated by the fire on the fire place and also radiates heat into such chamber.

The boiler, C, is an upright vessel, constructed with its opposite sides parallel and with an air chamber, G, recessed in it or extending down vertically into it, as shown in Figs. 4, 5, and 6, such air chamber being openat top to receive a hot air concentrator and deflector, H, which is a metallic box projecting downward from the top of the case, A, and made open at bottom and so arranged in the air chamber, G, and connected with one or more air discharge flues, I, I, as to cause air from the chamber, B, while the apparatus is in use to pass down between such deflector and the sides of the chamber, G, and from thence into the deflector where it will be concentrated and delivered into the escape pipes to be distributed by them to the difierent apartments to be warmed.

Arranged on each side of the boiler, C, and so that there may be an air space, L, or, L, between it and the boiler is a thin vertical auxiliary heater, K, or, K, which extends somewhat above the boiler and is connected with it by a series of horizontal bent pipes at, a, a, which not only open communication with the boiler and heater but serve to support the latter in place. F urthermore, a horizontal pipe, 6, connects the auxiliary heaters, K, K, at their tops and is connected with the boiler by a vertical pipe, 0.

Steam and water trial cocks as, y, may lead from the steam and water spaces of one of the auxiliary heaters so as to enable a person to ascertain at any time whether or not there is sufficient water in the boiler.

Besides being able to heat apartments by hot air distributed through pipes leading from the concentrator, my apparatus is also calculated to heat by means of steam carried through pipes and radiators. The drawings show at w, the carrying steam pipe. They also show at o, the return pipe or that which takes back to the boiler the steam which may be condensed in the leading pipes and radiators. The pipe to, extends to a radiator a, from which, the pipe, '0, leads to the boiler or one of the lower pipes thereof.

From the above, it will be seen that my said apparatus combines the advantages of a common hot air furnace, a hot water heat ing apparatus, and a steam heater. By means of it, I can not only heat pure air taken from the outside of a building, but introduce such air into a room from the hot air chamber of the apparatus, and should not such air be sufficiently warm, I can add to its heat when in the room by supplying it with more heat by the steam heating pipes or apparatus which may be in such room and be connected with the boiler. I also can heat the lower or nearer part or parts of a house by the hot air pipes and supply heat to more distant parts by means of the steam distribution pipes.

In the operation of the said heating apparatus, cold air is to be led into the lower part of the chamber, B. By circulating within such chamber it becomes heated, by the caloric radiated from the external surfaces of the boiler, the fire-place and smoke flue. It will rise in the said chamber and the boiler, in combination with the pipe H or its equivalent, depressed Within the same for heating and distributing the air in the manner and for the purpose set forth. 15

In testimony whereof I have hereunto set my signature.
