HOT-WATER H E'ATER.

SPECIFICATION forming part of Letters Patent No. 532,836, dated January 22, 1895. i

Application filed September 28, 1894. Serial No. 524,379- (No model.) i

To @ZZ whom it, may concern:

Be it known that LAHORACE K. TALLMAGE,

a citizen of the United States, residing in Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Hot-Tater Heaters, of which the following is a specification.

My invention relates to a new and improved hot water heatin g apparatus by which a large amount of heating surface is obtained at a minimum cost Vof construction, all of which will be fully and clearly hereinafter described and claimed, reference being had to the accompanying drawings, in which- Figure 1, represents a front elevation of my improved steam boiler complete. Fig.` 2, represents a Vertical section through one side of the boiler, on or about line a a, Fig. 1. Fig. 3, is a detached side elevation of onefsection or side of the body of the boiler, showing one Vside of its series of water tubes in their proper position projecting out therefrom. Fig. 4, represents a vertical section through a portion of one of' the sides cutting through the ribbed portion in which the fire box is located. Fig. 5, is a horizontal section on or about line a a, Fig. 2, showing a top View of the removable perforated air tubing surrounding the inner side of the fire box. Fig. 6, is also a horizontal section on or about line c c, Fig. 2, illustrating the preferred system of water tubes. Fig. 7, represents ahorizontal under side view of one of the horizontal air tubes that are located in the upper portion of the combustion chamber as will appearfarther on.

The body of the boiler, containing the water tubes and fire box consists of the parts l and 1, 2 and,2.A These fourk parts are all provided with a water chamber 3, and two of said parts are provided with a longitudinal tongue 4, projecting out from each narrow side, also with a tongue 5, at the bottom and a tongue groove 6, at the top. See Fig. 3. The other two parts, 2 and 2a', are each provided on one of their broad faces near each side or corner with a longitudinal groove 7, one on each side, adapted to receive the tongues 4 see Fig. 5, where these parts are shown put together thereby forming a substantially square fire box. In one of the side parts is an opening communicating with the water chamber, adapted to receive the inlet pipe 8, and

`through another is an opening leading into the combustion chamber and provided with the usual door- 9. See Fig. 1. On the lower portion of each inner side is a ribbed portion 10, consisting of aseries of parallel ribs and cross ribs leaving the air spaces 11, between them. bee Fig. 4. -Ihaveshown thesespaces as square, but they may be made in any suitable shape, the object being to interpose a non-conducting body of air 'between the fire and water space and thereby keep the coal fromlying close to the side where it is liable to be cooled or deadened by being too close tothe water in the water space. The object of these ribs is therefore to provide a series of dead air spaces in which the air cannot circulate but is held in said recesses or depressions between the fuel and the Waterside and thereby avoid the objectionabove mentioned.

Projecting from the upper inner side of each part l-1-2-2, is a Vseries of water tubes l2, rigidly secured thereto and communicating with the water chamber. The outer or free ends 13, of all these pipes l2, are closed watertight. Two opposite sides l and 1', for instance, are put together so that the pipes 12, pass between each other, see Fig. 2, also Fig. 3, where the alternate pipes are shown by dotted lines, the pipes in one section being placed sufficiently .below the pipes in the other so as to be substantially central between and below them as shown, one pipe being below the other in a vertical line. The pipes 12a, on the opposite Isections pass at right angles or crosswise between the pipes 12, in substantially the same manner, only the pipes of one section pass between the pipes in the other section in a horizontal plane instead of vertical as withformerpair of sections, see Fig. 6,"in this connection, where the preferred construction, or arrangement of pipes is shown, in which the pipes 12, in the two opposite sections 2 `and. 2a, pass in between each other in a horizontal plane, and the pipes 12, in the two opposite sections l and 1a (which pass at right angles or cross the pipes 12), also 'pass from each section in between each other in a horizontal plane. rlhis is the preferred construction because more pipes can begot in a given space than in the construction shown in Figs. 2 or 3.

IOO

Below the four main sections is the ash box 15, made in the usual way and provided with a door 1G. two ribs which hold it above the iioor. top is a hollow section 17, having a water chamber 17, and a vertical central opening 18. See Fig. 2. It is provided with a downwardly extending tongue 19, which extends entirely around it and tits in the groove 6,when put in place. On the top of this section 17, is another section 20, having a surrounding water chamber 20% This section is provided withachamber 21, a smoke pipe hole 22, and with a tongue 23, extending around near the bottom edge and is adapted to lit in the groove 24, in the top of the section 17. Y This top section being square, can be turned so as to bring the smoke pipe hole 22, either to the front or back or to any side.

The top portions, and the top of the four main sections, are all held together and provided with a water communication between all of the water chambers by means of connecting water tubes, 24e. See Figs. 1 and 2. The horizontal pipes 25, are each provided with a short branch pipe 26, connecting with the narrow sides of the sections i and la, and with a short pipe 26a connecting with the sections 2 and 2. The vertical pipes connected with the pipes 25, extend upward and connect by pipes 27, with the upper section and by pipe 28, with the top section 20. i

It will be seen that the above pipes not only provide a water communication between the several water chambers but also hold the several parts together. b

A series of screw threaded holes, are cut in the reversible top portion, each hole being lled with a plug 34, which is removed when it becomes necessary to reverse the upper portion having the hole for the smoke pipe. These plugs are used to stop the holes left by the connecting pipes when they are re-I moved from said top portion.

Four air pipes 29, extend up to the top of They are located in or about` the fire box. each corner of the `fire box, (see Fig. 2,) and extend down through the bottom of the ash box, and are open so that the air passes in,` in the direction of the arrows V, shown in` said Fig. 2. The top ends of these pipes 29,

to iit over the top of the pipes 29, so that the horizontal pipes 30, can be set thereon, and

thus be easily removable so that when worn or burned out they can be instantly replaced by new pipes. `They are put in `place sub-l stantially as shown in Fig. 5. Their free ends At the bottom of the ash box aref At the are chamfered oit so that they lit together as shownand the inner sides 32, are` provided with a series of perforations 33. See Fig. 2. The object of this construction is to carry highly heated air to the point where it is most required 'to mingle with the gases of combustion, andthe object in using metal for this is that it becomes more highly heated than brick.` Furthermore the tubes being small confine the air more closely so that it receives more heat in passing through.

Thecirculation in this boiler takes the usual course, the cold water passing in at the lowest point and the hot Water passing out above it as will be readily understood. The air passes vinto the pipes 29, in the direction of the arrows V, shown in Fig. 2, and it becomes sufficiently heated on its way up to combine with the gases of combustion 'as it passes out through the perfo'rations in the horizontal pipes 30. 35, in Fig. 5, represents the `Iire grate.

I claimas my invention-'- 1.
