SPECIFICATION forming part of Letters Patent No. 396,105, dated January 15, 1889. Application filed August 15, 1887. Serial No. 247,007. (No model.)
To all whom it may concern:
Be it known that I, CLARENCE O. MULFORD, of Streator, in La Salle county and State of Illinois, have invented certain new and useful Improvements in Steam-Generators, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, in which Figure 1 is a central vertical sectional view through the front and back of my invention. Fig. 2 is a horizontal sectional view on the line 2 2 in Fig. 1. Figs. 3, 4, 5, and 6 are views of boiler-sections in the different forms used in constructing my device in its preferable form.
Myinvention relates to steam-boilers of the class known as tubular or sectional boilers.
The object is to simplify and cheapen steamgenerators in which this form of boiler is used, to increase their effectiveness, and to adapt them to be used advantageously with bituminous coal as fuel.
To these ends the invention consists in the construction and combination of parts herein described, and pointed out particularly in the claims.
In the drawings, A represents the base upon which the boiler rests and in which the grate B is hung.
0 represents hollow ring-shaped boiler-sections, preferably made of cast-iron. They are arranged horizontally one above the other in such a manner that free circulation from one ring to another is permitted through the orifices 0. Some of the sections are not complete rings, the front part being omitted, as shown in Fig. 4, to permit access to the inclosed space through the doors E E. The sections are secured together by the vertical bolts F, which extend from the top to the bottom of the boiler through the orifices 0. Two or three of the upper sections are provided at their proximate points with the vertical flanges c, which extend about two-thirds of the distance around said sections, being absent at the rear side thereof, as shown in Figs. 1 and 3. By this means slots 0 are formed between adjacent rings at the top rear side of the boiler.
D represents a dome, which is placed upon the upper section 0, and thus the space J within the rings is completely inclosed except boiler sections or rings themselves, thus rendering a distinct and separate fire-pot unnec-' essary. It will be further noticed that the space, .I, inclosed by the boiler-sections and the dome forms a combustion-chamber as well as the upward or-direct draft flue, and that by this arrangement the heat from the fire is led upward in contact with the boiler-walls until it escapes through the slots 0 Outside of and surrounding the boiler is a jacket, I, preferably of brick-work, and built so as to inclose a space, N,'between it and the boiler, as shown. This space acts as a divingflue, and it is divided into an upper and lower line, at and a, respectir ely, by the horizontal partition G, which extends about two-thirds around the boiler and rests upon the brickwork, as shown. The communication between the upper and lower flues, n and a, is at the front of the boiler, as shown most plainly in Fig. 2.
L represents the smoke-pipe, which leads from the fine a at the rear side of the boiler.
The section or ring 0, which lies near the grate B, i provided with a supplemental ring, K, connected with it through the pipes k. This ring K is so placed that it lies substantially in contact with the fire, and is of great service in generating steam, inasmuch as it offers considerable heating-surface at a point where the heat is most intense. The upper section or ring 0 is also provided with arms 0, which meet near the center of said ring, and additional heating-surface is afforded by these arms at a point where the heat, deflected by the dome D, will come in contact with said arms on all sides.
The operation of the device is as follows: The heat from the fire on the grate passes upward within the space J to the top thereof. It is deflected by the dome, and, after having come in contact with all the boiler-surface eX- posed on the inside of the rin s 0, passes out through the slots 0 into the diving-flue a.
llere the heat is drawn downward and around the boiler on both sides thereof to the front, where it passes the partition G into the lower due, 21. It then passes downward and around to the smoke-pipe. In its course theheat has thus come in contact with the entire exposed surface of the boiler both on the outside and inside of the ring-sections, and its full eit'ect to produce steam has been utilized. It has not been obliged to pass through any small inclosed flues which could become choked by the products of combustion, and the device is therefore especially adapted to burn soft coal.
,3. The coin] )llltlTiOl] ot' a series of connected liorizontally-arranged watiiw-rin with a suiiable dome, an d flanges with openings between two or more of said rings, substantially as and for the purpose s1;)ecified.
In a SbQELlll-gGllGl'ittOl, a boiler composed of horizontal water-rings, the upper two or three of which rings have vertical flanges at their meeting-points, which flanges are cut away at the rear of said boiler, substantially as and for the purpose specified.
4:. The combination of a boiler com posed of horizontal water-rings secured together sub stantially as specified,whereby a direct-draft flue is formed within said rings, and a dome placed upon said rin gs, with a jacket surrounding said boiler and inclosing, a space which serves as a diving-flue, a horizontal partition dividing said diving-iilue into an upper and lower ti ue, connections between said direct flue and diving-flue at the back of the boiler, connections between the upper and lower diving fiues at the front oi the boiler, and the smokepipe at the back of the boiler, substantially as specified.
CLARENCE MU'LFORD.
