WATER-LEG FIRE- BOX.
SPECIFICATION forming part of Letters Patent No. 425,943, dated April 15, 1890.
Application iiled December 7, 1889. Serial No. 332,994. (No model.)
To aZ whom it may concern:
Be it known that I, JOHN J. HOGAN, a citizen ofthe United States, residing at Brooklyn, Kings county, New York, have invented certain new and uset'ul Improvements in Vater-Leg Fire-Boxes, fully described and represented in the following specification and the accompanying drawings, forming a part ot the same.
My present improvements relate especially to the lire-box of a water-heating boiler for use in connection with hot-water radiators, and the construction shown in the drawings is adapted to be used with additional watersections superposed thereon, as shown in my patent applications, Serial Nos. 292,642 and amico.
The invention will be understood by reference to the annexed drawings, in which- Figure lis an elevation of the construction, viewed from the tire-door side. Fig. 2 is a vertical section on line .e in Fig. 3. Fig. 3 is Ia plan of the under side of section O of the boiler. Fig. a is a vertical section on line z c in Fig. 3 and oc fr in Fig. 5 with a breeching applied to the top. Fig. 5 is a scctional plan on line @c in Fig. 4r. Fig. 6 is a sectional plan on line y y in Fig. 4; and Figs. 7 and S are aplan and vertical section through the center of the water column and a portion of the pocket g beneath the same, upon a large scale, to show the thimble-connections.
The nre-box consists in three cast-iron sections A, B, and C and ash-pit D, provided with grate E. The section A encircles the iire-pot and is lined with nre-brick. rl`he section B surrounds the combustion-chamber above the tire-pot, and the section C forms a dome or cover to the lire-box. The sections A and B consist in annular water-jackets, the lower section around the lire-pot being divided by an internal vertical partition into two Water-channels, one contiguous to the ire and the other to the exterior of the section. In section A, s is the partit-ion; c, the wateiechannel next the tire-box; c7., the exterior channel.
The water-channels are closed at the top and bottom and the interior channel is provided with several pockets g, projected toward the iire in the repot and provided upon their upper sides with thimble openings h to connect with the section B. An inlet-nozzle t' for the return-iiuid from the radiator system is provided at the rear of the section A and admits the fluid to the channel (l, as indicated by the arrows a in Fig. 5.
An aperture 7c is formed in the partition s at the opposite side of the section to admit the water from the channel d to the channel c and thimble-openings 7L, as shown by the arrow o in Fig. A deflector 7c is provided at the middle of the opening 7c to defiect the water in two currents in opposite directions into the channel c toward the thimble-openings h.
The section B contains but one water-channel d and is provided internally with three water columns g', arranged vertically over the pockets g and connected thereto by thimbles Z, inserted in the openings 7L. These water columns are open laterally into the channel d', so that the water passes freely from the channel into all the columns. The section is provided externally with several pockets m, communicating freely with the same channel, and the upper sides ofthe pockets are formed with thimbleopenings n, by which they are connected by the thimbles o with similar pockets p upon the upper section O. This section is a flat hollow plate forming the crown or top of the fire-box and is provided with thimblc openings h2 for connecting it with the pockets g by thimbles Z. The upper surface of the plate is dome-shaped or highest in the middle, the center being provided with the outlet-nozzle Q, from which the heating-Huid would be conducted to the heatingradiators or into the upper sections ot the boiler, if such were used. The pockets g upon the inner side of the section B project prominently into the combustion-chamber and operate as vertical water columns to receive the strongest effect of the re and to produce a Astrong upward circulation from the lower section A into the upper section C. The circulation in the water columns g and the thimbles o is shown by arrows o in Fig. 2.
Such an upward movement of the fluid would tend to the generation of steam where the water was displaced and to the overheating of the metal in the water columns and in the lower section. Such tendency is, however,
IOO
wholly corrected by the provision of the external thimbles o, which connect the outer part of the upper section with the outer part of the section B, and thus provide an ample passage for the downward movement of the colder fluid to supply the pla'ce ot that which is heated in the water columns. -My previous applications referred to herein also show provision for such downward circulation in the exterior water-channels that are colder than the water-space of the boiler, and my present application diers from such constructions partly in the use of an annular partition in one or more of the boiler-sections to divide the same into internal and external Water-- channels, partly in the combination Vof the water columns g with the section around the tire-box, and partly in the entire construction shown herein, in which the Alower section alone is divided into inner and outer waterchannels and receives the return-fluid in the outer channel. Such retu rn-iluid is prevented by the partition s from contact with the heated metal close to the tire, and is materially warmed by its contact with the partition s, through which heat is conducted from the hotter contents of the channel @,fbet'ore it enters said channel.
In Figs. 3 and 4 smoke-passages r are shown, perforating the top section, the Walls of which passages intersect the Water-space wit-hin the section, and in Fig. 4 a breeching H is shown applied over the top of such section, with a smoke-pipeI to carry oit the products of combustion.
In case it were desirable to increase the capacity of the boiler, other sections similar to the sections C would be superposed thereon and connected at the pockets p and central nozzle Q, the water columns extending only upward to the lower side of the section C, and such construction for the superposed sections is shown in mybefore-mentioned applications, but forms no part of my present invention.
It will be understood that the water columns g present a comparatively small body ot' water (somewhat isolated from the adjacent water-ring) to the intensest heat of the lire, and thus secure the absorption of such heat in the most eiteetive manner in a portion of the water which is most favorably 1ocated for a direct upward movement.
As shown in Fig. 4, the Water columns g form a direct vertical passage from the inner channel e in the iire-pot ring to the interior ofthe crown-plate C, so that the upward movement of the water in the Water columns tends most forcibly to draw a continuous current of fluid from the vicinity of the fire-pot and force it in a highly-heated condition into the upper water-section of the boiler. As the water-rings form a hollow Water-leg like that in an upright wrought-iron boiler', I have termed my invention a water-leg lire-box.
Having thus set forth the nature of my invention, what I claim herein isl. In a boiler having a number of hollow sections superposed one upon another, an annular hollow section around the lire-pot provided with an external Water-inlet, an annular vertical partition opposed to such inlet and forming inner and outer water-channels within the ring, an aperture in the partition for the passage of t-he water to the inner channel, and one vor more apertures conducting the water upward from such inner channel to the Watensections above, as and for the purpose set forth.
2. In a boiler, t-he combinatioinwith the al1- nular section A, provided with the annular partition s, forming outer channel d, having inlet t', and inner channel c, provided with thimble-openings 7L, of the annular section B, having a single Waterchannel provided internally with the water columns g and with the pockets m, having thimble-openings n, and the section C, provided with thimble-openings, and thimbles connecting the section C with the pockets m and water-'columns g, as and for the purpose set forth.
3. In a boiler, the combination, with the an.- nular section A, provided with the annular partition s, forming outer channel d, having inlet t', and inner channel e, provided with thimble-openings h, of the annular section B, having a single water-channel provided internally with the water columns g and with the pockets m, having thilnble-openings n, and the section @provided with thimble-openings, and thimbles connecting the sectionv C with the pockets fm. and water columns g, the section B having an opening in one side for the lire-door, and the several sections being separated by smoke-spaces u and provided with marginal flan ges t to confine the smoke. to such spaces, substantially as herein set forth.
In testimony whereof I havehereunto set my hand in the presence ot' two subscribing witnesses. i
