Be it known that I, EUGENE M. FANCHER, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of thoroughly utilize the heated products of combustion thereof, both by exposing as much heating-surface as possible to the same and by the novel direction given the course of said heated products throughthe furnace; second, to prevent the accumulations of dust on the surfaces exposed to the .heat; .third,

to so construct the waterways as to promote 7 chamber to the exit of the furnace, so that in process of cooling or condensation the heat will be maintained at a higher degree near the fire-chamber andat less and less degree the farther said products get from the same. This I accomplish by the means hereinafter fully described, and as particularly pointed out in the claims. f

In the drawings, Figure l is a perspective view of my improved furnace, showing a portion of one side thereof broken away. Fig. 2 is a similar view with the front section of the furnace removed. 3 is a rear view of the front section. tion of the furnace. Fig. 5 is a side elevation of the rear section of the same. Fig. 6 is a horizontal section through the furnace, taken on dotted line 6 6, Fig. 1. Fig. 7 is a detail view showing a section through the lower portion of two abutting sections ofthe furnace, taken on a horizontal plane just above the grates and the broken-away end portion of the grate j ournaled in the open bearings between the same. the same, showing a section taken on dotted line 8 8, Fig. 7, looking in the direction indicated by arrows.

Fig. l is a rear eleva.

Fig. 8 is a detail view of My improved furnace consists of a number of transverse sections,the exterior dimensions of all of which correspond to such an extent that when properly assembled they make a rectangular structure, the sides and top of which it is customary to protect by a veneering of asbestos cement and the front and rear of which are left exposed. The front and rear sections A and B, respectively, are in so far as they are designed to close the ends of the furnace and afford a means of access into and exit from the same different in construction from the central or mediate sections 0 C, which latter embody the salient features of my invention and can be used in greater or less numbers, according as it is desired to build a large or small furnace. Each of these central sections 0 comprise two legs a a, the outer faces of which when the furnace is properly assembled form part of the side walls of the same. These legs are hollow from the top, where they are connected by the horizontally-. disposed steam-chamber D, to a point just below the gratesE and are connected by a slanting waterbar I) about midway their height, which spans over the grate-surface and assists in forming the roof of the fire-chamber X. Below the water-bar b the width of the hollow portion of the legs is less than the width of the section until a point just below the grates is reached, whereupon thewidth of the hollow portion is increased to correspond to that of the section of which it forms apart. When several of said central sections are properly connected, this lessened width of the legs forms open bearings a for the journals of the rocking grate-section E, from which they can be very easily removed or into which theycan be dropped into place, as

desired. These grate-sections E are each-provided with a depending arm E near one j ournal, and this arm near its lower end is provided With a lateral studs, that enters an opening in the horizontal shaking-bar e, and this shaking-bar extends out through a suitable opening in the front section and is provided with a suitable lever f to vibrate it and rock the grates, substantially as shown in the drawings. 1

The under side of the water-leg a is corrugated, and the inner vertically-disposed surfaces of the water-bars that are exposed to and form the top wall of the fire-chamber are corr ugated, so as to present as much heating-surface as possible without affording a lodgment for the dust from the fire. The water-bars I) are connected at a point about their centers of length with the transverse steam-chamber D at the top of the section by an inclined tubular upright F, which in turn is connected at about its center of height with the right-hand water-leg a by a short tubular waterway. g, and this short waterway g is connected about its centerof length by an inclined verticallydisposed tubular wall 7b, which thus makes two arched longitudinal lines with the steamchamber D. The width of the water-bar Z), bridging over the fire-chamber and all of that part of each central section comprising the steam-chamber, tubular walls, waterway, &c.

- located between the tubular upright and the the chamber formed above the same and be tween said tubular uprights on one side, the legs of the sections toward which the uprights leg of the section away from which said upright inclines, is of the same width as the said section; but the width of the water-bar 1) between the upright F and the leg of the furnace-section toward which said upright inclines is slightly narrower than the width of the section. Thus when several of these central sections are brought together the wator-bars 1) form a grated passage, up through which the products of combustion pass into incline on the other side, and the steam-chamber overhead. The fines or passages above the water-bars 1), formed on the other side of the upright F, have their joints in such close contact that they are practically closed to the direct action of the products of combustion from the fire-chamber and are open only at the front and the rear of the furnace.

The center of length of the narrower portion of the water-bars b is connected with thesteam-chamber D by a tapered-shape column G, which is narrowest at its lower end, and this column is connected by a series of laterally-projecting inclined tubular branches h h to the upright F and the adjacent water-leg a of the section, thus forming a tree through which the water is free to circulate, substantially as hereinafter fully described. These sections are connected by means of suitable nipples i at the center of the steam-chamber next the top of the section and by nipples jj, located at points j j near the bottom of each leg just above the plane of the fire-grates.

At the front of the furnace the forwardmost central section is connected to the front section A in substantially the same manner as it is connected to its fellows. This front section has a tubular formation substantially similar to the central sections 0, except that it is minus the short waterway g and tubular wall h, and instead of having a grate has its legs hollow almost to the floor and has a transverse tubular member 7*, connecting said legs. Just below the part 5', corresponding in. position to the water-bar b, the front section is provided with a fire-door H, of suitable construction, and below the transverse member r it is provided with a suitable door I, through which access can be had to the ashpit of the furnace below the grates. Just in front of the tubular formation of the central sections of the furnace above the plane of the water-bars b the front section is provided with a swell front J, of rectangular proportions, of such dimensions that it extends from one water-leg a to the other of the sections of the furnace and from just above the plane of the water-bar b to a plane below the steamchambers of the section D, so as to establish an end communication with. all the longitudinally-disposed passages or flues of the furnace above the plane of the water-bars I). In order to facilitate access to all of the passages above the water-bars b, (throughwhich the products of combustion must pass while in transit through the furnace,) I prefer to hinge the swell front J to the front section, as shown in the drawings. This, however, need not be done unless desired. The rear section B is likewise of a tubular formation. Its construction above the plane of the waterbars is substantially the same as that of the central sections; but below the plane of said water-bars it has a hollow water-wall M,which forms the rear wall of the fire pot or chamber, which extends as far down as the grate. Below the plane of the grate-bars this rear section isprovided with a door L, through which access can be had to the lower part of the furna'ce. Above the plane of the grate-bars the rear wall of said rear section is cut away and is covered and closed by aboX-shaped shell or drum N, with the lower part of which the pipe leading. to the chimney connects. This shell N has a horizontal partition 02 on about the plane of the waterways g and an oblique verti cal partition 0, which contacts with the tubular upright F of the rear central section 0 and, together with partition 11', forms a continuation of the lower flue T, formed by the legs a, water-bars b, waterways g, and uprights F to the exit or chimney-opening. The remainder ,of the interior space of shell N is open and establishes a communication between the chamber 0 above the grated water-bars and the arched fiues S S on the other side of uprights F and above waterways J.

In operation the products of combustion from the fire-chamber first enter chamber 0, then pass into shell N. From thence they pass forward through the arched flues S S into the small front J and then down into and back through the flue T below waterway g out of the furnace. If desired, a damper P may be made in the horizontal partition n of the shell N, by opening which a direct draft may be had through the-same from chamber 0 out of the furnace. If. desired, the rear of the shell or drum N may, back of flue T, be provided with a suitable checlovalve V. Any suitable arrangement may be provided for this purpose, however, Itwill thus be observed that byalways bringing' the more IIO - highly-heated products of combustion against the right side of the furnace and thendirecting them in a less-heated state through flues S and then in a still cooler state directing them back through flue T, I give the water in the tubular parts of the furnace an upward movement, then a movement from right to left, and then a downward movement on the left-hand side of the furnace, which continues easily and without undue friction all the time the furnace is in operation. The incline and slant given to the interior tubular constructions of the furnace assist in affording an easy and comparatively unobstructed chance for the steam to rise and escape into the steam-chamber and the water to descend unobstructed and prevents priming. These. and other advantages will be observed by the practical furnace-maker, all of which I desire to be understood as coming within the scope of my invention so long as substantially the same means are employed.
