JOHN L. BOGERT, OF FLUSHING, NEW YORK.
STEAM-BOILER.
SPECIFICATION forming part of Letters Patent No. 255,484, dated March 28, 1882.
Application filed December 16, 1881.
To all whom it may concern:
Be it known that I, JOHN L. BOGERT, of
Flushing, in the county of Queens and State of New York, have invented an Improvement in Steam-Boilers, of which the following is a specification.
Steam-boilers have been made with two intersecting ranges of inclined tubes placed above the fire and passing into the angles of the fire -chamber, and water has circulated through these.
My invention is made for obtaining a very strong and compact boiler with a large extent of heating-surface, and for promoting a rapid circulation of water through the pipes without the risk of foaming.
I employ two vertical tube-sheets, corrugated horizontally and facing each other, with ranges of inclined pipes passing each other at opposite inclinations, the corrugations being at the same angle to a vertical plane as the tubes are to a horizontal plane, in order that the tube-sheets may be at right angles to the tubes at the places where such tubes pass through the sheets, to allow ot' the ends being swelled and turned in the manner usual in inserting boiler-fines; and I provide a water chamber or boiler at each corrugated tubesheet in the form of half-cylinders, in order that the boiler may resist pressure without requiring as many stay-bolts as usual in tubular boilers, thus simplifying and rendering less expensive thisimproved boiler.
In the drawings, Figure 1 is a vertical section of the improved boiler, and Fig. 2 is a horizontal section of the same at the line a: :v.
The tube-sheets a aareintended to occupy a "ertieal, or nearly vertical, position. They are corrugated or bent in alternately-opposite directions, each bend being wider than the diameter of the tubes employed. The tubesheets are perforated for the passage of the tubes 1) I), such perforations being in the flat portions of the bends, and such bends or corrugations being at right angles to the axes of the tubes. Thetubes I) extend upwardly from the flat portions 1 ot'the sheet a to the fiat portions 2 of the sheet a, and the tubes I) extend upwardly from the fiat portions Q of the tube-sheet a to the flat portions 4 of the (No model.)
tube-sheet a, the holes being so disposed that the ranges of tubes b are intermediate bev tween the ranges of tubes b. The tubes are secured at their ends by swelling and turning, as usual. v
The boiler-shells e e are semicircular, and they are riveted to the flanges of the tubesheets a a, and these shells are preferably extended across, or are connected from one to the other, as at f, so that any pressure that might tend to separate the semi-cylindrical boilers is taken on the connecting-plates f, i11- stead of upon the tubes.
The top h and bottom 7c of each semi-cylindrical portion of the'boiler are made inany suitable manner. They will usually be flat and braced with suitable tie-bolts, and the steam is taken away by pipes, as usual.
The fire-chamber is below the circulatingtubes. It may be made of fire-brick, with ordinary grate-bars. There will usually be a blow-oft and feed-pipe at Z, below the boiler.
I prefer to line the connecting-platesf with fire-brick, as at m. The connectionsfmight be hollow water-spaces; but these willadd to the expense of the boiler and require-to be heavily braced with tie-bolts.
Suitable man-holes are provided in the semicylindrical boilers, also doors in the platesf to give access to the tube-space.
The water will circulate in the tubes in the directions indicated by the arrows, and will form eddies as it passes out of the upper ends of onerange of pipes and descends and enters the lower ends of another range, as indicated by the arrows.
There is ample space in the semi-cylindrical boilers for the steam to rise, although the circulation is short and rapid. If the water-level is as high as the upper end of the highest tubes, the water will circulate through all the tubes; otherwise steam will issue from the highest tubes into the boilers. Steam-drums may be provided, as at an, and the products of combustion be taken off by the contracted funnel, as at 0.
I claim as my invention- 1. In a boiler, two water-chambers having their inner plates corrugated, in combination with ranges of tubes inclined in opposite directions, the ends of such tubes passing through the plates at right angles to the surfaces, substantially as set forth.
2. In a boiler, the combination, with two semicircular shells, of the corrugated tubesheets and the ranges of tubes inclined in 0pposite directions, with their ends passing through the tube-sheets, and being at right angles to the surfaces where such tubes pass through, so as to connect the water-chambers, substantially as set forth.
3. In a boiler, the semi-cylindrical shells and corrugated plates, in combination with the ranges of tubesinclined in opposite directions, and the connecting-plates f, substantially as I5 specified.
Signed by me this 10th day of December,
JOHN L. BOGERT. Witnesses:
