HOT-WATER FURNACE.

SPECIFICATION forming part of Letters Patent No.749,740, dated January 19,1904.

Application filed July 29, 1903. Sacrial No- ,167,433. (No model.)

T0 aZZ whom it may concern.-

Be it known that I, FRED LUMYER, a citizen of the United States, residing at North Monroeville, county of Erie, and State of Ohio, have invented new and useful Improvements in Hot-Water Furnaces, of which the following is a specification.

My invention. relates to improvements in hot-water furnaces, and is composed of two separate heads having water-spaces provided therein and connected by means of a series of pipes.

The object of my improvement is to provide a means of bringing the surfaces of the inner series of pipes in close contact with the fuel, whereby a larger number of square inches of heating-surface is brought within the radius of the heat-waves generated from the fuel or other combustible material.

A further object is to provide a means of thoroughly circulating the water from the time it is admitted to the inner head through the medium of suitable inlet-pipes until it is finally forced out through suitable apertures provided in the outer'head.

I attain these and other objects by the construction of the hot-water furnace which is illustrated and described in the accompanying drawings, in which Figure 1 isan end elevation of the inner and outer heads of the furnace, showing an end view of the return-bends which connect a series of pipes. Fig. 2 is a front view in crosssection, taken on the line Y Y of Fig. 3, showing apertures provided in the. inner and outer heads, into which the series of pipes are fitted, also apertures through which the water is admitted into the inner head and the apertures through which the water is forced out in the outer head. Fig. 3 is a side view in crosssection, taken on line X X of Fig. 1, showing the series of pipes connected to the inner and outer heads through the medium of suitable return-bends, also a side view in cross-section of the furnace frame and door.

In constructing my hot-water furnace I provide an inner head a and an outer head 6, preferably of the shape shown in the drawings, Figs. 1 and 2. The outer head is adapted to fit around the outer edge of the inner head, as shown by reference-letter c. A series of suitable pipes cl arescrew-threaded and adapted to fit suitable apertures e, providedin the innerand outer heads. It will be noted that the apertures are provided in the heads so as to leave the apertures provided in the outer head at a higher plane than the apertures provided in the inner head, the purpose of whichis to leave the pipes wider apart at the point of their connection to the inner and outer heads than they are at the point of their connection to the return-bends f. It will be noted that the pipes are all connected on an incline with relation to. the inner and outer heads, providing a means of raising the water as it passes through the pipes. In the upper portion of the inner head a suitable flue g is provided,through which the smoke and gases pass out. Suitable grate-bars it are provided and attached to the furnace by any ordinary fastening means. An ordinary furnace-front '1, and door 3' are provided and adapted to contact with the return-bends f.

In the operation of my furnace water is admitted through the apertures is. It then circulates or flows through the apertures e into the pipes n, which are connected to the inner head of the furnace. It is then carried through these pipes and through the return-bends f and delivered into the pipes 12, which are connected to the outer head. The water is then forced out through the apertures 0, provided in the top of the outer head. It will be noted that this provides for a thorough circulation of the water from the time it enters the inner head through the inlet-pipe and is delivered to the apertures 7c until it is forced through the series of pipes connecting the inner and outer heads until it is finally forced out through the apertures 0,-as practically all of the pipes are brought in close contact, utilizing a large proportion of the heat generated.

Slight changes in the construction of the pipes or heads can be made without deviating from the principle involved in my invention.

Having fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. A combination of an inner and outer head having suitable apertures provided,therein and adapted to connect a series of pipes communicating with said heads, substantially as and for the purpose described.

2. A combination of an inner and outer head with suitable apertures provided therein, a series of pipes adapted to fit said apertures, return-bends connecting said pipes whereby the inner and outer heads are connected together.

3. A hot-water furnace composed of an inner head, having a series of apertures provided through which water is delivered, a series of apertures provided in said head, a series of pipes fitted in the said apertures, an outer head adapted to fit the exterior of the inner head, having a series of apertures provided therein into which a series of pipes are fitted, areturnbend connecting the pipes so as to leave the pipes on an incline with relation to said heads, a series of'apertures provided through which water is forced out.

4. In a hot-waterfurnace, a combination of vided therein, a series of pipes fitted to the outer head-,a second series of pipes fitted to the inner head, return-bends connecting said pipes, whereby the inner and outer heads are brought in communication with each other, providing a means of circulating the water after its admission, substantially as and for the purpose described.
