IMPROVEMENT IN STEAM-BOILERS.
Specification tbrming part of Letters Patent No. 136,2 l4, dated February 25, 1873.
[0 all whom it may concern:
Be it known that I, EDWARD It. Cons, of Pawtucket, in the county of Providence and State of Rhode Island, have invented a certain new and useful Improvement in Steam-Boilers.
My improvement consists in the novel location, construction, and arrangement of an inclosed water-jacket or protector surrounding the main flue within the steam-space, and is particularly applicable to the upright boilers of steam fire-engines; and I do hereby declare that the following specification, taken in connection with the drawing furnished and forming part of the same, is a true, clear, and exact description of a boiler involving my invention.
Referring to the drawing, Figure 1 represents, in cross vertical section, a boiler containing my im 'irovement. Fig. 2 represents the same in horizontal section at the line .r ain Fig. 1.
A represents the tire-box; B, the smoke tubes; and G, the main smoke-flue. l) represents the water-space, which extends upward from the base of the boiler to the water-line E. F is the steam-space, extending upward from the water-line E, and surrounding partially the smoke-tubes B and the main fine U, to the point where it leaves the boiler. G represents the water-jacket. It is an annular chamber surrounding the main smoke-flue above the slnoketubes, and is located entirely within the steam-space of the boiler.
As the water-jacket may be incidentally employed with more or less advantage as a feedwater heater, I have described it as also capable of performing that function.
The induction thereto in this instance is effected by the pipe H, which may be made to in the chamber it is impossible to overheat the line, and it thereby obviates the possibility of the backing down of the walls of the smoke-flue, as is sometimes the case with b0ilers as ordinarily constructed. By having the water-chamber not only subjected to the action of direct heat escaping upward from the furnace and within the main smoke-flue, but also to the direct action of the steam under pressure in the steam-space, the water therein is more promptly heated without either deadening the tire or lessening the regular produc tion of steam, than can be accomplished with any other boiler with which I am acquainted.
Although I have thus described the waterjacket as adapted to the purposes of a feedwater heater, I desire distinctly to disclaim the same as a part of my invention. The an raugeme-nt of a feed-water heater surrounding the uptake of a boiler and located within the steam-space is, broadly, the invention of Eugen Neumann, and is covered by Letters Patent granted on his application, dated October 22, 1872, No. 132,484.
I will now, therefore, proceed to explain how the desirable features of my invention may be attained without the employment of the waterjacket as a feed-water heater.
It will be observed that the pipe I extends from the water-jacket to a point inside the boiler, near its base, far below the water-line; also, that the pipe H extends downward from the water-jacket outside of the boiler. To the lower end of this pipe H an ordinary stopcock is to be applied. When steam has been more or less generated within the boiler the stop-cock is to be opened, and the pressure of the steam upon the water inside of the boiler will force it up into the water-jacket and keep it full to a greater or lesser extent, as may be desired. Preferably, however, in such case the pipe H will be turned in to the boiler at its lower end, and the pipe I extended outside of the boiler; or the pipes may remain as they are shown, with the addition to pipe H within the water-jacket of a tubular neck, extending to a point within the jacket adjacent to its upper end.
I am aware that before my invention locomotives have been provided with annular water-heaters located on top of the boiler and surrounding the base of the smoke-flue, and which were in turn surrounded by the cinder- 7 box, in which the unconsumed solid products of combustion were deposited.
I am also aware that it has been proposed to place within steam-boilers, adjacent to the walls of a furnace and the uptake, parallel surrounding partitions with intervening spaces open at top and bottom, whereby a circulation of water might be kept up as a protection against undue heating of the adjacent parts of the boiler; but I am not aware that, prior to my invention, an inclosed protecting waterjacket was ever combined with the main flue within the steam-space of the boiler.
Having thus described my invention, I claim as new and desire to secure by Letters Pat ent- The combination, with the main flue or uptake in a steam-boiler, of a strengthening and protecting inclosed chamber or water-jacket surrounding the flue, located within the steamspace, and provided with communicatingpipes, arranged substantially as described, whereby a-full supply of water may be kept therein, and discharged therefrom outside of the boiler, as and for the purposes specified.
EDWARD R. COLE.
