IMPROVEMENT IN STEAM-GENERATORS.
Specification forming part of Letters Patent No. 204,203, dated May 28, 1878; application filed March 20, 1678.
To all whom it may concern:
Be it known that I, MICHAEL OULLEN, of. Hartford, in the county of Hartford and State of Connecticut, have in vented certain new and useful Improvements pertaining to a Steam- Generator, of which the following is a specification, reference being had to the accompanying drawings, where j Figure 1 is a view of a generator embodying said improvements, in central vertical section, looking toward the front. Fig. 2 is a detail view of the boiler-cap detached from the boiler and turned bottom upward.
The letter a denotes the cylindrical part or -case of the boiler; b, the top plate of the boiler; and c, the bottom plate.
The letter 01 denotes the side or cylindrical part or case of the fire-box, rising from the bottom plate 0 of the boiler; and e, the crown sheet of the fire-pot.
The letter f denotes a cap sitting on the upper end of the boiler; g, a jacket outside the boiler. There is a smoke-pipe leading from this jacket (not seen in the drawings) to conduct smoke to chimney.
I will here give the function and operation of the parts just described, premising that ,there are smoke and hot-air tubes h running from the crown-sheet of the fire-box to and through the top plate of the boiler, and another set of smoke and hot-air tubes, 1', running from the top plate of the boiler to its bottom plate. I
The smoke, gases, and heat generated in the fire-box pass up through the pipes or tubes h, and, being prevented from escape otherwise by the cap f, pass down through the tubes 5, thence up inside the jacket g, and off through the smoke-pipe to the chimney. When a direct draft is needed to kindle or freshen the fire, or the like, the damper j is opened by means of the rod j.
I will now describe other parts of my generator. Within the cap f is a compartment or box, k, for superheating the steam, which I will herein term the superheater. Steam finds access to it from the boiler through the pipe land exit through the pipe m. This superheater is, or may be, vertically traversed by the pipes at, which give greater area of heating-surface.
They are capable of serving an additional purpose, to wit: They are so located that each one stands directly over one of the tubes which perpendicularly traverse the boiler. The top plate of the cap f is removable, and then,by a common straight swab or brush, the boiler-tubes can be reached and cleaned through the pipes 'n, thereby obviating the necessity for removing the whole cap and its contents.
Another feature: Within the cap f is a compartment or box, 0, for heating feed-water before it goes into the boiler. The water comes in through the pipe 10 and goes to the boiler through the pipe 1. This feed-water heater is traversed by vertical pipes 0 for giving'increased area of heating-surface, and each is located over one of the boiler-tubes, so that the boiler-tubes can be cleaned with a straight brush through them without removing the whole cap and its contents.
I wish it to be distinctly understood (see first clause of following claims) that I do not claim, broadly, an arrangement which takes the heat, &c., from the top of the fire-box and conducts it by a return-flue to the bottom plate of the boiler; and I limit myself, in this particular, to pipes which run from the firebox to the top of the boiler, where, by means of a cap, the heat, &c., is made to descend through boiler-tubes and out of the lower end of the boiler.
The pipe 1' conducts the feed-water to the bottom of the boiler.
It will be observed that the feed- Water heater and the superheater are substantially duplicates in construction and arrangement, except that one part of the feed-water heater is connected to the bottom of the boiler. I therefore, in the following claimsin the first clause thereofmake specific claim to the superheater, only meaning thereby to claim the combination specified, whether used as feed water heater or superheater.
I claim as my invention- 1. The boiler provided with hot-air tubes,
provided with tubes the pipes 12 r, and the the cap f, the pipes Mn," and the superheater' feed-water heater 0, provided with the tubes kyprovided with tubes n, allx'combinecl and arranged substantially as described, and. for the purposes set forth.
2. The boiler provided with hot-air tubes, the cap f, the pipes I m, the superheat'er k,
0; alleombined as described.
