UNITED STATES PATENT OFFICE.,
CHARLES Il. FARVELL, OF ATCHISON, KANSAS.
STEAM-GENERATOR.'
SPECIFICATION forming part of Letters Patent No. 422,754, dated March 4, 1890.
Application filed July 22, 1889. Serial No. 318,255. (No model.)
To all whom t may con/cern:
Be it known that I, CHARLES I-I. FARWELL, a citizen of the United States, residing at Atchison, in the county of Atchison and State of Kansas, have invented new and useful Improvements in Steam-Generators, of which the following is a specification.
This invention has for its objects to provide an improved steam-generator, whereby the boiler is eihciently and perfectly heated by an economical consumption of fuel; to provide novel means for utilizing the heat in the escaping products of combustion; to provide a novel construction for the perfect circulation of the water to provide a lnovel arrangement of water-back and diving smoke-nue, whereby the escaping smoke and other prod ucts of combustion are utilized to heat the side of the water-back, which is opposite or remote from the lire-box, and also the waterleg of the boiler, and to provide novelmeans whereby the smoke in its passage to the chimney is caused to traverse the entire top and side walls of the boiler; These objects I accomplish bythe features of construction and combination of devices hereinafter described and claimed, reference being made to the acl companying drawings, in which* Figure lisa perspective view broken away in front and at one side to more clearly exhibit the construction; Fig. 2, a vertical sectional view, and Fig. 3 a sectional view on the line x Fig. 2.
In order to enable those skilled in the art to make and use my invention, I will now describe the same in detail, referring to the drawings, where--l The numeral 1 indicates a brick-work or other base having-in one side wall a longitudinal soot pit or flue 2, in the opposite sidewall a similar longitudinal soot pit or iiue 3, and
between said walls an ash-pit 4, over which is a iiregrate 5, of any construction suitable for the conditions required, said grate being here shown as composed of two sections capable of being rocked or rotated by a handllever and connecting-rod as usual.
The waterchamber 6 of the boiler comprises inner and outer vertical shells 7 and'S, arched.
base 1 at one side of the grate and extends i longitudinally from the front to the rear wan ter-head. The fire chamber or box 16 is coextensive in length with the space between the water-heads, and the upper end ofthe watenback terminates at a short dist-ance beneath the arched part 9 of the inner shell 7.
The inside sheets of the water-heads are connected by a series of horizontal watertubes 17, the external surfaces ot' which throughout their length are exposed to the direct action of the smoke and other products of combustion from the fire. The water-back 15 is located parallel to and at a short distance from the Water-leg 12, to provide an intervening diving-flue 18, which receives the smoke at its top, conducts it *'down toward the longitudinal flue 3 in the base 1 to the ascending flue 19. This ascending flue connects at its top with a flue 20, arched over the boiler and communicating with a descending side flue 21, that connects at its lower i portion with an escape-opening 22, whichin practice is connected with any suit able chimney.
The soot-pit 2 underlies the smoke-line 21 and serves to receive and retain soot and other matter, which can be removed as occasion demands by means of the opening and closing door 23, the iiue 3 being also adapted to be cleansed through a similar door 23. The iiues 19, 20, and 21 are formed by an ex ternal shell or jacks 2l, resting on the base 1, surrounding the boiler and separated a sufficient distance therefrom, such external shell or jacket extending from the front to the rear waterhead and causing the smoke and other products of combustion to traverse the entire area of the side and top walls of the boilera The inner sheet of the front Water` head is provided at its bottom with a tube or orifice 25, that places the lower portion of the said water-head in communication with the lower portion of the water-back, while the upper portion of the inner sheet of the front water-head is furnished with an overliow-orice 26, that places the upper part of the front water-head in communication with the interior of the boiler. The rear end of the waterback at or near its top communicates by an overliow-tube 27 with the upper portion of the rear water-head. The rear ends of the water-legs communicate at their base with the rear water-head by the orifices 28, and the two water-heads are placed in communication by the series of horizontal water-tubes 17, connected to the inner sheets of the said l heads. The front of the base is provided with a draft-regulating' door 30, and the front water-head has a lire-door 31, these doors being of any desired construction.
The feed-water is introduced by any suitable pipe-connection with a water-supply, and, as shown, the water in the front waterhead enters the lower part of the water-back by the supply-tube 25, and thence overflows by tube 27 into the rear water-head. The water entering the boiler through the overflow-opening 26, passes to the water-legs 11 and 12 through the orilices 28 tothe rear water-head, and thencevby the water-tubes 17 back to the front water-head and through the orifice 26 int-o the boiler, as before, thus causing a circulation of water through the lower part of the water-legs, the rear water-head, the water-tubes, and the front water-head, and also a circulation through the water-back and both water-heads.
I do not confine myself to a single waterback between the water-legs, nor to the exact arrangement shown of the smoke-escape openin-g 22. A water-gage 32 and a steamgage 33 of suitable construction are provided, as usual.
Having thus described my invention, what I claim is-- Q 1. The combination of a boilerl having a pendent waterdeg at each side, a nre-chamber between such legs, the front and rear water-heads in communication, respectively, with the front of the boiler and the rear lower portion of the water-legs by a top overflowopening and base-orilices, a vertical divingflue beside one of the water-legs, the watertubes connecting the water-heads, and a shell or jacket surrounding the boiler and constituting a continuous flue in communication with the nre-chamber through the medium of the vertical diving-f1 ue for causing the smoke and heat to traverse the entire outer surface of the water-legs and the top of the boiler, substantially as described.
