UNITED STATES PATENT v JOHN OBRIEN, OF ST. LOUIS, MISSOURI.
STEAM-BOILER.
SPFCIFIOATION forming part of Letters Patent No. 262,976, dated August 2.2, 1882. Application filed February 14, 1882. (No model.)
To all whom it may concern Be it known that 1, JOHN OBRIEN, of St. Louis, Missouri, have made a new and useful Improvement in Steam-Boilers, of which the following is a full, clear, and exact description, reference being had to the annexed drawings, making part of this specification, in which Figure 1 is a front elevation, half in section, of a boiler having the improvement; Fig. 2, a rear elevation; Fig. 3, a plan, halfin horizon tal section; and Fig. 4, a side sectional elevation.
" The same letters denote the same parts.
The present invention is adapted more especially to boilers of the horizontal cylindrical type, and it relates especially to the boilerwalls.
A represents a stea m-boiler of the description under consideration. B represents the furnace; U, the grate; D, the ash-pit; E, the flue leading from the furnace, and F the uptake at the rear end of the boiler.
G G represent the boiler-walls. They mainly occupy the usual position of such a boiler-wall. In place, however, ofthe walls being solid, and serving merely as a means for inclosingthefurnace and flue,they are hollow and of suitable material and construction for holding water, and for the purpose of heating the water passing into the boiler A. To this end each well G is composed of ashell, 9, i nclosin g a water-space, g, the shell being extended preferably, as shown, from about the level of the grate 0 upward to about the level of the water-line a of the boiler A, at which level the wall is curved or turned inward to or toward the boiler A, and in a longitudinal direction the walls extend from the front end, a, of the boiler rearward to the end a, and thence around in rear of the boiler,
but preferably not so as to meet in rear of the l boiler, but leaving the space that may be utilizedas a doorway, H, to provide access to the uptake F. Ihe walls rest upon supports I I, and at the top are held to the boiler by means of ties J J.
The wateris supplied to the spaces 9 through a suitable supply-pipe, K, the pipe leading from a pump or device suitable for supplying water a to boilers. The pump or device is not shown,
its construction being well understood. From the spaces 9 the water passes into the boiler A through pipes, such as at M, and which are preferably arranged at or near the top of the space 9. The pipe Mis furnished with a check-valve, N, to prevent the return of the water from the boiler A.
0 represents a blow-off valve in a pipe, 0, leading from the spaces a.
The walls'G G, therefore, in addition to confining and directingthe heat currents beneath the boilerA, serve as heaters,wherein the water is heated in passing to the boiler, for the walls in practice absorb sufficient heat from the passing heat-currents to heat the water flowing to the boiler through the spaces 9'', and even when the walls are well heated to generate steam within the walls, and when the valves N are opened or omitted the walls GG-and boiler A constitute in effect a continuous steam-generator.
The heat of the furnace B is thus utilized to better advantage than heretofore in connection with boilers such as shown. The spaces hitherto needed for feed-water heaters are not now required, and without requiring more room than is now taken up with the ordinary furnacewalls a greatly-extended heating-surface is ob tained, and the generatorin effect isin sections, (the walls G G and boiler A being detachable from each other,) enabling it to be readil y transported. The pipe M is used to conduct into the boiler A any steam that may generatein the extreme upper part of the wall G.
A pipe, Q, (indicated in dotted lines in Figs. 3 and 4,) connects the boiler A with the lower part of the water-spaces 9, providing for a circulation between the spaces 9 and the boiler at that point.
I claim The combination of the boiler A, hollow walls G G, pipes K, M, M, and Q, and blowoffO, substantially in the manner and for the purposes set forth.
JOHN OBRIEN.
