BOILER- SPEGIFICATION forming part of Letters Patent No. 538,105, dated April 23, 1 895.
Application filed February 20, 1895. Serial No. 539,097. (No model.)
To all whom it may concern.-
Be it known that 1, WILLIAM H. FETTER, a citizen of the United States, residing at Mansfield, in the county of Richland and State of Ohio, have invented certain new and useful Improvements in Boilers, of which the following is a full, clear, and exact description, ref erence being had to the accompanying drawmgs, forming part of this specification.
My invention relates to vertical water tube steam generating boilers, and has for its obect the improved construction of the same whereby their steam producing capacity is increased with great economy in the fuel re quired to operate the same.
The novelty of my invention will be hereinafter set forth and specifically pointed out in the claims.
In the accompanying drawings:--Figure 1, Sheet 1, is a side elevation of a boiler embodying my invention and with the casing in section. Fig. 2, Sheet 2, is a sectional elevation oFf thle same through the dotted line .r-nc of The same letters of reference are used to indicate identical parts in both figures.
A, is the outside shell or casing, tubular in form and preferably constructed of fire brick, and having at its top a metal hood B, communicating with the smoke flue. Within the lower part of the shell, which is somewhat eularged, is the grate, C, for holding the fuel which is supplied from any suitable door, D. Beneath the grate O, is the ash pit, E. Located horizontally under the casing is a mud drum, F, having a central hollow leg, G, whose upper end is riveted to the dished bottom plate of a lower drum, H, just above the fire pit in the shell, as seen in Fig. 2. The top plate of this drum is connected by braces a, with the interior of the leg, G. The shell of the drum, H, fits within and is riveted to an upturned exterior flange of the dished bottom plate for giving greater strength and durability to the drum. Connecting the interior of and extending up from the drum, H, are a series of water tubes, I, whose upper ends enter and are secured by rolling and beading to the bottom of a steam drum, J, which is supported thereby within the top of the shell but without contact with its sides, thus leaving a space around its exterior for the passage of the products of combustion.
Extending centrally through the drum, J, is
an equalizing flue, K, for the passage of a part of the products of combustion. Opening from the opposite sides of the drum, J, and extending through the shell are pipes, L, whose centers entering the drum are at the normal water line of the boiler. These pipes extend down outside of the shell and have their lower ends communicating in any suitable manner to the mud drum, F.
In Fig. 1, M, is the outlet pipe for the steam, and in Fig. 2, N, is the water gage. The leg, G, is preferably surrounded with fire brick,
as shown, to protect it. 0, represents the blowoff outlet for the mud drum.
By the above construction I have produced a high potential generator with many advantages, for, by the use of the circulating pipes, L, of which there may be any number desired, opening from the upper drum at the water line and communicating with the mud drum below the grate, which mud drum is also connected with the lower drum, a perfect and equal circulation is also maintained, and an equal weight of water is always sustained both above and below the fire. The same construction also prevents foaming or priming as all impurities will at once flow out through the pipes, L, and descend through the same into the mud drum. Again, by opening the blow-off cock from the mud drum, the circulation is instantly increased and all foul matter is thrown 6E both from the drum, H, the drum, J, and
the mud drum.
Instead of elbows connecting the lower end of the pipes, L, with the mud drum, as shown,
Ts may be employed to connect two or more boilers in batteries. Again by means of the central flue, K, in the drum, J, and the annular space between the said drum and the shell, the heating of the tubes is equalized without deflectors and steam is generated very rapidly.
Having thus fully described my invention, I claim 1. In a boiler, the combination of an exterior shell, a steam drum in the upper part thereof, a second drum above the grate, water tubes connecting the two drums, a mud drum beneath the grate, having a leg communicating with the lower drum, and circulating pipes, exterior of the shell and connecting the mud drum with the steam drum at the normal water line, substantially as described.
2. In a boiler, the combination of an exteterior shell, a steam drum in the upper part thereof, but out of contact therewith, and having a central line, a second drum above the grate having a dished lower plate, with exteriorly riveted flange, a mud drum beneath the grate, having a leg communicating with the lower drum, water tubes connecting the two drums, and circulating pipes exterior of the shell and connecting the mud drum with the steam drum at the normal water line, substantially as described.
3. In a boiler of the class described, the combination with the drum H, above the grate, and mud drurn F, below the grate, of the water leg G connecting the two and protected by a brick covering, substantially as described.
M. H. FETTER.
