Application filed May 8, 1905. Serial No. 259.475.
To all whom it neay concern:
Be it known that I, ALVIN M. OUsHINe, a citizen of the United States of America, residing at Springfield, in the county of Ha1np den and State of Massachusetts, have invented certain new and useful Improvements in Steam or Hot-Water Boilers of that Class known as CoiLB oilers, of which the following is a specification.
This invention relates to the class of boilers, and more particularly to that class of boilers used for heating by means of steam or hot water or for power purposes.
Broadly considered, the invention consists in employing a central standard or feed-pipe which is located centrally over the fire-box and is closed at its upper end, while the lower end is contracted and bent into a U-shaped form and connected with a vertical standpipe. The central standard or feed-pipe has connected therewith a number or series of spirally arranged coils, the inner ends of which are connected to the standard or feedpipe and the outer ends of the same are connected to another vertical stand-pipe parallel with the central standard. The coils are arranged in horizontal planes and parallel to each other. Located above the standard or teed-pipe is a drum or steam-chest which is in communication with the two standpipes, and passing centrally through this drum is a smoke-flue for the escape of the products of tends upward and leads into a stand-pipe, at
which point the U-shaped pipe is increased in diameter, as shown at the point (i.
e designates a stand-pipe at the left of the central standard or feed-pi e and extends parallel therewith and slight y above the top of the standard a, where it is connected with a drum or head f by means of the opening g.
At the right of the standard or feed-pipe a is a stand-pipe h, which is made or composed of sections, as shown. This stand-pipe is closed at its lower end by a cap '11, and the upper end of the same communicates with the interior of the drum or steam-chest f by the opening The drum f has the smoke-pipe or flue 76 passing centrally through the same and immediately over the upper closed end m of the standard or feed-pipe.
A series n of spirally-coiled pipes are connected to the standard or feed-pipe a at their inner ends, as shown at 0 in Fig. 2, while their outer ends are connected with the standpipe h in any suitable manner, as by the screw-threads p.
q designates a portion of the brickwork of the fire-box, and r designates a portion of the firegrate, which is located in the brickwork in the ordinary manner.
The reference-letters s, t, u, and o designate, respectively, the feed-pipe, blow-oil pipe, the steam-pipe, and the ordinary steamgage, the location and arrangement of which, however, forms no part of my invention, they being merely shown in a conventional way.
The operation of my improved boiler is as follows: As the water in the standard or teedpipe a becomes heated, even only a few degrees, circulation of the same immediately takes place, causing the heated water in the pipe at to rise and flow from the same into the spiral coils 71-, through the opening 0, and around the coils to the outlet w and into the stand-pipe h, where the heated water will rise and flow from the pipe h into the drum or steam-chestf through the opening 3', as in dicated by the arrow 00. The heated water after circulating through the drumf descends through the stand-pipe e, as indicated by the arrow 1 passing from thence to the contracted point (1 in the pipe 6, and from this point it circulates through the portion 0 of the U- shaped bend which connects the pipes at and e. As the water flows from the pipe 6 through the U-shaped parts 0 and into the standard or feed-pipe a it is again reheated and rises in the pipe a, where it flows out into the spiral coils at through the openings 0 at the inner ends of the coil, thus repeating the operation 7 of circulation.
2 designates the level of the water in the drum or steam-chest f.
It is thus seen that by my improved boiler I provide a large heating or radiating surface for the heated gases from the furnace to come in contact with. This large heating surface is accomplished by means of the series of coils n, which are attached to the standard or feedpipe (1, and it is to be understood that a large or small number of these can be attached to the standard a, as required, thus materially increasing the efl'iciency of the boiler either when the same is used for heating. or for power purposes. It is also to be understood that my boiler may be used as a feed or return supply without changing any of the essential features thereof.
The dimensions shown in the drawings'being only for the purposes of illustration, I may vary them in any way that I see fit without departing from the spirit and scope of my invention.
Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is
1. In a boiler of the class described, a central standard or feed-pipe having a closed top, the lower end of which has a contracted portion and bent into a substantially U- shaped form and extending upward and conver ing into the lower end of a stand-pipe, saic stand-pipe being in parallel arrangement with the standard or feed-pipe, a second stand-pipe located on the opposite side of the standard or feed-pipe from the stand-pipe previously mentioned, said second stand-pipe being also arranged in parallel alinement with the standard, a drum or steam-chest located above the upper closed end of the standard and communicating with the two stand-pipes, a series of spiral coils arranged horizontally, the inner ends of which are connected to the standard or feed-pipe and their outer ends to the said second stand-pipe. I
2. In a boiler of the class described, a cental standard or feed-pipe, a stand-pipe parallel therewith, a second stand-pipe also parallel with the standard, and communicating means between the standard and the two stand-pipes consisting of a series of spiral coils forming communication between the standard and one of said stand-pipes, and a drum for connecting the two stand-pipes at -their upper ends, and forming communication between them, a curved or U-shaped element connecting the lower end of the standard and one of said stand-pipes at its lower end, the upper end of the standard or feed-pipe, and the lower end of the other stand-pipe being closed.
In testimony whereof I have affiXed my signature in presence of two witnesses.
ALVIN M. CUSHING.
