ED\VIN REYNOLDS, OF MILVAUKEE, VISCONSIN.
WATER-TUBE BOILER.
SPECIFICATION forming part of Letters' Patent No. 580,196, dated April e, 1897.
Application filed NOVembel 23, 1896. Serial No. 613,075. (No model.)
To all whom, t may concern.'
Beit known that LEDWI REYNOLDS, a citizen of the United States, residing at Milwaukee, IVisconsin, have inventedanew and useful Improvement in Tater-Tube Boilers, of which the following is a specification.
The object of my invention is to improve the Stirling type of boiler; and the invention consists in the features and combinations hereinafter described and claimed.
ln the accompanying drawings, Figure l is a transverse section of my improved boiler, taken on line l of Fig. 3; Fig. 2, a longitudinal sectional elevation taken on line 2 of Fig. l, and Fig. 3 a longitudinal sectional elevation taken on line 3 of Fig. l.
In constructing my improved boiler I elnploy two mud-drums A and I5, two elevated steam and water drums C and D, having their water spaces placed in communication by pipes c, two inner banks of tubes E and F, and two outer rows of tubes G and H, connecting the upper and lower drums, respectively. The outer rows of tubes extend in a substantially vertical direction and are connected to the upper and lower drums at the same sides of the boiler, respectively, while the inner banks of tubes extend diagonally and are connected to the upper and lower drums at opposite sides of the boiler, respectively. Each of the outer rows and inner banks may consist of a single row of tubes or several rows, as desired.
As shown in the drawings, the furnace M is arranged between the two mud-drums and extends back from the front wall or setting to a bridge-wall M', which is provided with two openings m underneath the grate-bars. These openings communicate with a vertical slot m in the bridge-wall and thus provide for any draft that may be necessary to complete cornbustion. It will be understood, however, that these special features may be used or not, as desired.
The heated gases going out from the furnace enter into and among the tubes of each of the inner banks. Fire-brick partitions or walls e f on the outer sides of these banksthat is, the sides farthest from the furnacearrest the gases in their upward passage and hold them in contact with the lower portion of the tubes until they pass back to a point or opening I near the rear wall or setting of theboiler. The vgases then escape into the vspaces .I between the side walls or settings and fire-brick partitions adjacent to theinnerbanks of tubes, in which spaces they are brought into contact with the tubes of both the outer rows, the upper portion of the tubes of both the inner banks, and the lower portion of both the elevated steam and water drums. They then pass forward in such spaces to a point or opening K near the front wall-or setting, after which they escapeinto the space L above the fire-brick walls or partitions e f and pass back therein and in contact with the pipes c to the i'lue or chimney.
Feed-water may be introduced into either or both of the upperor lowerl drums; but I prefer to introduce it into both the upper drums. After passing into the boiler the feed-water iills all the drums and tubes up to the waterlevel in the upper steam and water drums', after which the water circulates through the various parts as required by differences in temperature and conditions in different parts of the boiler.
The steam-spaces of the upper drums may be connected by suitable pipes or not, as desired, and of course suitable means for drawing off steam should be employed.
The principal advantage of my invention is that it provides for making practically a double boiler in a single space; but other advan tages, especially in construction and as to directing and controlling the course of the gases and water circulations, also exist.
I claim Y l. In a water-tube boiler, the combination of two upper steam and water drums having their water-spaces placed in communication, two lower mud-drums, two outer rows of tubes connecting the upper and lower drums at the same sides of the boiler, respectively, two inner banks of tubes connecting the upper and lower drums at opposite sides of the boiler, respectively, and tire-brick walls or partitions covering the outer sides of the inner banks of tubes from their point of crossing to a point near the lower mud-drums, whereby a cone is formed in the lower part of the boiler, substantially as described.
2. In a water-tube boiler, the combination of two upper steam and water drums having IOO their Water-spaces placed in communication, tWo lower mud-drums, two outer rows of tubes connecting the upper and lower drums at the same sides of the boiler, respectively, two inner banks of tubes connecting the upper and lower drums at opposite sides of the boiler, respectively, nre-brick walls or partitions at the outer sides of the inner banks of tubes forming a cone in the lower part of the boiler and an inverted cone in the upper part of the boiler, an outlet or opening near the rear wall or setting for the escape of gases from the lower cone into the side spaces, and an outlet or opening near the front wall or setting for the escape of gases from the side spaces into the upper inverted cone, substantially as described. y
3. In a steam-boiler furnace, the combination of the inclo'sing walls; steam drums c i 5 mounted upon the upper portion thereof; z" mud-drums connected to `and supported by said steam-drums by a series of vertical andl diagonal cross-tubes; tiling laid upon said cross-tubes to form lues or chambers within the furnace; walls extending the length of the 25 furnace beneath the mud-drums; a hollow' bridge-wall located about midway of the fur nace between said walls, and extending upf-1l ward toward the cross-tubes; a grate or grated. mounted between the mud-drums at their for# 3o ward ends; and openings from the ash-pit bolow the grate into the hollow bridge-wall.
