WATER-H EATER.

erncrrrcnrron'rorming'prt of Letters intent No. 687,419, dated November 2e, 1901.

Application filed March 25, 1901. Serial No. 524,730. (No modell) To @ZZ whom t may concern.- Be it known that I, RICHARD BEAUMONT,

fof Kankakee, in the county of Kankakee and'` 'State of Illinois, have invented certain new series of water-drums s-upported within a shell 'over a combustion-chamber.

The device consists in the matters hereinafter set forth, and more particularly pointed Aout in the appended claims.

In general terms a `device which embodies the principal features of my invention comprises a combustion-chamber, an outer cylindrical shell rising therefrom, and a series of cylindrical water-drums supported in the shell over the combustion-chamber, the upper of said drums supporting a smoke-chamber and the remaining drums being suspended yfrom the upper drum in tandem within the shell.

In the drawings, Figure l is a view in vertical section of a water-heater embodying the salient features of my invention. Fig. 2 is aA View in cross-section through the heater on line 2 2 of Fig. l. Fig. 3 is a view in crosssection through one of the drums, taken on line 3 3 of Fig. l.

Referring to the drawings, A represents a combustionchamber of ordinary pattern. As shown herein, it is provided with the usual grate a and ash-pit a and side walls a2, which extend upwardly above the grate, so as to form a circular chamber with Haring sides. Extending upwardly from the upper margin of said combustionchamber and supported thereon is a cylindric metallic inclosure or` shell B. This may be inclosed, if preferred, in masonry setting C, as herein shown, or may be lagged out and jacketed. The upperend of said shell supports on its upper margin a water-drum D, formed of cast-iron, or built of sheet metal, if preferred. Said water-drum D is formed with flues and a deflector-plate, as hereinafter more fully described, and carries an upper smoke-chamber d', made, preferably, of sheet metal and adapted to lead the smoke and gases of combustion from the flues of the drum D to a suitable smoke-pipe E. Obviously-said`smoke-chamber may be of any desired form. As herein illustrated, it is formed by a cylindrical side wall d2 and an upper end wall d3, the latter having an aperture adapted for connection with the smoke-pipeEintheusualmanner. Thedrum D, which is of less diameter than the shell B and is dependent therein, is formed by a flat upper plate d4, which extends over the upper margins of the shell B and is secured thereon at its margin d5, so as to form a tight joint,

a cylindrical side wall d6, depending from thev plate d4 within the shell B and of considerably less diameter than the internal diameter of the shell B, and by a horizontal bottom plate d?, secured to thelower margin of the side wall d6. Passing through said drum are a plurality of vertical flues F, said iiues being arranged symmetrically in said shell or drum and being formed with converging side walls d8,so as to be in form truncated cones. The upper plate d4 of said drum is provided with an upwardly-projecting boss or nipple d9,which is centrally located andiis provided with an aperture suitably screw-threaded or otherwise fitted for connection with a water-outlet pipe G, which extends upwardly therefrom to the smoke-chamber d/ and into the smoke-pipe E, from which it is led in any direction desired. A depending boss d10 is centrally located on the lower surface of the bottom plate C17 of the drum and is likewise provided with an aperture screw-threaded for pipe connection,said aperture beingin approximate alinement with the aperture of the upper nipple d. Midway between the upper and lower end plates d4 and @Z7 of the drum D is a horizontal deector-plate H, which is supported by resting on or being connected with the side walls d3 of the flues F. By this arrangement of the parts the detlector-plate H is interposed in the line of flow between the upper and lower apertures of the bosses or nipples d and d10. Suspended from the drum D by means of a connecting-pipe I, secured by screw-threads in the aperture 0f the depending nipple d10, is a water-drum K, which is similar in the main to the drum D, being provided with upper and lower horizontal walls IOO ' drum.

7c 7c', cylindrical side wall k2, and preferably equal in external diameter to the side wall d6 of the drum D, and ilues F', similar in shape to the llues F and equal in number. The upper horizontal end wall k projects beyond the side walls 7a2 a sufficient distance to form an annular horizontal flange k3, whose external diameter is slight-ly less than the internal diameter of the shell B, so as to afford a narrow passage between the flange and the shell. The drum K is further provided with an interior deilector-plate II', similar to the deflector I-I, and outer bosses or nipples kf h5, centrally apertu red and in triorly screw-threaded for connection with the connecting-pipe I and a dependent connecting-pipe I. Said pipe I' serves as a connection and support for a series of two or more drums K K2 de pendent therefrom, the intermediate drums, as K', being similar in every respect to the drum K, and the lowest one, as K2, of the series having no deliector plate and having in place of the lower boss in the center of'its bottom plate a side boss or nipple 76"', centrally apertured and screw-threaded for the reception of a feed-water pipe L, which extends therefrom out through the wall of the shell D and the side of the furnace for convenient connection with any water-supply. In mounting the drums it will be observed that the connecting-pipes I, I', and I2 are so fitted that when the drums arescrewed home thereon the ilues of each drum are staggered with respect tothe flues of the adjacent drums.

The operation of the device is obvious. The products of combustion and the heat arising from the combustion-chamber A are conducted by the walls of the shell B to the lower drum K2, against which they impinge and are divided, a part passing upwardly through the converging walls of the lues F3 and a part passing up between the side walls of the drum and the side walls of the shell B around the upper horizontal flange ofthe The currents from the flues strike against the bottom wall of the drum above it owing to the staggered position of the fines and are diverted along the bottom of the drum to the ues, through which they pass up to and against the bottom of the succeeding drum K'. The part of the current passing around the side wall of the drum is partiallyarrested by the horizontal flange thereof, so as to thoroughly heat the side walls, and then escapes around the flange and passes up to the next drum, where it is again momentarily checked by the flange. Thus the heat-currents from., the combustion-chamber are caused to pass over nearly the entire surface of each drum until they finally reach the smoke-chamber d above the upper drum D,

from whence they escape through the smokepipe E. In this manner the greater portion of the dru m-surfaces are heated by direct contact with the hot gases. The funnel shape of the flues affords a comparatively large wallsurface, which, owing to its position with re'- gard to the currents of hot gases, is highly heated. Water is fed into the lowest drum K2 through the pipe L. There it comes in Contact with the heated bottom plate and the side of said drum and the flaring side walls of the ilues F3 and thence passes upward through the connecting and supporting pipe I2 into the next drum K. Here it impinges against the dellector-plate H2, which causes it to flow outwardly around the walls of the flues F2 and the side walls of the drum, so as to come in contact with the heated surfaces thereof before it passes up through the connecting-pipe I into the next drum, where it is again deflected by the plate H. By this means a thorough circulation of the water against the thoroughly-heated walls of the through the entire series of drums and reaches the discharge-pipe G.

An important advantage in this form of construction is in the method of supporting the drums inthe shell B. The drums hang entirely free from the shell B and are therefore independent therefrom and are not subjected to any strain of internal expansion. Furthermore, they are very easily mounted and dismounted for repairs or replacing the parts, it only being necessary to screw each drum home on its connecting central pipe. Any amount of heating-surface can be obtained by mere multiplication of the drums and proportionate increase in the size of the combustion chamber and shell B without the usual complication arising in many forms of construction of water-heaters due to increase of weight and the multiplication of supporting devices.

It will be understood that Ido not limit myself to the specific form of construction herein shown, except as set forth in the appended claims.
