JIRO MIYABARA, OF TOKIO, JAPAN.
WATER-TUBE'BOILER.
SPECIFICATION forming part of Letters Patent No. 747,080, dated December 15, 1903.
Application filed October 12, 1903. Serial No. 176,626. (No model.)
T0 at whom it may concern:
Beit known that'l, JIRO MIYABARA, asubject of the Emperor of Japan, and a resident of Tokio, Japan, have invented a new and useful Improvement in Water-Tube Boilers, of which the following is a specification.
This invention is an improvement on the water-tube boiler described in my Letters Patent of the United States No. 633,699, dated September 26,1899; and its objectis to provide a simple and efficient water-tube boiler in which there shall be aneffective circulation of Water and steam.
It has more particularly forits object to provide a structure in which the steam which is produced is passed from the top chamber or chambers of the boiler through a series of tubes into a steam drum or chamber, so as to become superheated to a material degree by the gases of the combustion-chamber.
In the accompanying drawings, Figure l is a vertical section of one form of a boiler containing my present invention. Fig. 2 is a vertical section of another form thereof. Fig. 3 is a vertical section of a third form thereof. Figs. 4 to 10, inclusive, are details.
1, 2, 3, 4, 5, and 6 are horizontal waterdrums arranged in two Vertical series to form the front and back walls of the combustionchamber 7. The drums in each vertical series are connected together by the interposed junction-boxes or vertical tubes 8. The two combustion-chamber waterwalls thus constructed are connected together by the series of water-tubes 9, which extend diagonally across the combustion-chamber above the fire-grate 10. In each of the water-drums, excepting the top and bottom ones, is preferably provided a diaphragm or deflector 11, so arranged as to separate the streams of water and steam circulating upwardly through the water-tubes 9 from the stream of water circulating downwardly through the junction-boxes 8. The water-level in the boiler is at 12, so that the uppermost of the drums already referred to constitute combined water and steam drums.
13 is a steam drum or chamber located above the water-level in the position shown in either of the drawings.
14 and 15 in Figs. 1, 2, 4, 5, and 7 are two series of steamtubes which connect the steam-drum 13 with the combined steam and WEttGI' drums 1 and 2, respectively. In Figs.
3 and 6 there is only one series of tubes 14, which connects the steam-drum 13 with the combined steam and water drum 1 or 2. When arranged as shown in Fig. 6, the tops of drums l and 2 should be connected by a pipe 16 for conveying steam from one to the other.
22, 23, 24, and 25 are deflecting-plates Within the combustion-chamber compelling the gases to pursue a circuitous course among the water-tubes.
26 is the flue.
For detaining the steam after leaving the steam and water drums of the boiler within the superheating-gases of the combustionchamber I provide a circuitous passage from the steam and Water drums to the steamdrum 13. The mechanical construction by which such passage is made circuitous may begreatly varied; but the following are examples': As shown in Figs. 4 and 5, it consists of the casings 17, 18, 19, and 20, inclosing the ends of the tubes 14 and 15, so as to compel the steam to take the circuitous route indicated by the arrows, and thus pass repeatedly through each series of pipes. These casings may be made of cast or wrought iron or steel or other suitable metal and so constructed that they may be removed in order to clean, examine, or replace the superheating-tubes. As shown in Figs. 9 and 10, said mechanical construction consists of a spiral deflector-plate 2l,inserted in each of the tubes of the series 14 and 15, whereby the steam is given a circuitous course as it passes: through each of said tubes. As shown in Fig. 7, said mechanical construction consists in giving each of the pipes in the series 14 and 15 a loop form, so that each pipe substantially crosses the combustion-chamber and returns to the drum 13. I. do not wish to limit myself to either of said forms of construction.
Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a water-tube boiler, in combination two series of horizontal water-drums constituting opposite walls of the combustionchamber and extending above the Water-level, oppositely-inclined water-tubes connecting said two series across the combustion-chamber, a steam-drum and a series of steam-pipes in the combustion-chamber connecting one or more of said water-drums above the waterlevel with said steam-drum.
'2. In a water-tube boiler, in combination, two series of connected horizontal waterdrums constituting opposite walls of the combustion-chamber, a superheated steam-receiver drum, pipes connecting said steam-receiver drum with said water-dru ms provided with means whereby the steam is given a circuitous course after leaving said water-drums.
3. In a water-tube boiler, in combination, front and back water-drums, a superheated steam-receiver drum, a series of steam-pipes connecting said water-drums with said steamdrum, casings located within said drums whereby the steam is compelled to pass repeatedly through said series of pipes and spiral guide-strips inserted in said steampipes.
4. In a water-tube boiler, in combination, two series of connected horizontal Waterdrums constituting opposite walls of the combustion-chamber and extending above the water-level, oppositely-inclined water-tubes connecting said two series across the combustion-chamber, a steam-drum exposed to the upper portion of said combustion-chamber above the water-level and a series of pipes also exposed to the upper portion of said combustion-chamber and connecting said waterdrums above the water-level with said steamdrum.
5. In a water-tube boiler, in combination, two series of connected horizontal waterd'IulIlS constituting opposite walls of the combustion-chamber and extending above the water-level, oppositely-inclined water-tubes connecting said two series across the combustion-chamber, a steam-drum located above the space between said two series of water-dru ms, two series of steampi pes exposed to the prodnets of combustion and connecting both of said series of water-drums with said steamdrum above the water-level.
In testimony whereof I have hereunto signed my name in the presence of two subscribing witnesses.
JIRO MIYABARA.
