CHARLES H. HUTCI'IINSON, OF MANCHESTER, NEIV HAMPSHIRE.
FEED-WATER HEATER.
SPECIFICATION forming part of Letters Patent No. 623,216, dated April 18, 1899.
Application filed February 9, 1898. Serial No. 669,631. (No modell To aZZ whom it may concern:
Be it known that I, CHARLES H. I-IUTOHIN- SON, a citizen of the United States, residing at Manchester, in the county of Hillsborough and State of New Hampshire, have invented certain new and useful Improvements in FeedlVater Heaters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention is shown applied to a furnace-mouth feed-water heater; and its object is to cause the water to enter the heater at a higher temperature than when it is passing through the injector. This I accomplish by the novel means set forth in the following specification and claim and clearly illustrated in the drawings accompanying and forming a part of the same, of which 7 Figure 1 is a broken elevation representing one end of a boiler and its furnace, which has two doors,and myimproved connections properly applied thereto. Fig. 2 is an enlarged detached vertical section of my improved attachment. Fig. 3 is an enlarged plan View of a detail of my invention, and Fig. 4 represents the opposite side of the same part.
Similar letters designate like parts in all the views.
A is the boiler-l1ead,and B its furnace front, which is provided with two doors I).
A furnacemouth feed -water heater is shown by dotted lines, the bottom receiving water from the injector through the pipe 0, while the top is connected with the boiler just below the water-line by the pipe D.
My improved attachment consists of a cylinder E, which is out into the feed-pipe at the proper point to connect at e by a pipe D to the lower portion of the boiler A, as shown. The bottom of said cylinder E is connected to the inlet-orifice of the feed-water heater by the pipe 0, and near its top a pipe 0 is coupled, which leads to an injector.
A system comprising only a furnace-mouth feed-water heater connected to an injector by the pipe 0 and to the boiler by the pipe I) would operate and be to a certain extent effective; but my improvements render such a heater more effective by drawing a limited amount of heated water from the boiler and causing it to unite with that from an injector before entering the feed-water heater, which produces a circulation of the contents of the boiler and heater, greatly facilitating the heating capacity of the latter. This is accomplished by means of the pipe D, connecting the lower portion of the boiler with a cylinder E at e, the upper portion of said .cylinder being connected with an injector by a pipe 0'. In order to effect my purpose, the water entering said cylinder from an injector should be discharged into the same at a point below the inlet 6, so as to produce a suction and to draw a certain quantity of hot water from the boiler, the mechanism for accomplishing this purpose being illustrated in Fig. 2 of the draw-' ings. The water from the injector is thrown uponall sides-of the cylinder E by means of an attachment F, secured to the lower end of the pipe 0 and consisting of a shell adapted to fit over said pipe at f and provided interiorly with a cross-barf,centrally perforated, as shown in Figs. 8 and 4, and having its lower end flaring, as at f Fitting the interior conical portion of the part f is an adjustable conical valve G, attached to a stem 9, which is threaded to the perforation in said cross bar f and extends upward through the pipe C and through a stuffing-box e at the top of cylinder E, where it is supplied with any convenient means for being rotated, as the disk 9.
The object of this construction is to force the circulation when the steam-pressure is low, and thus effect a saving of fuel.
Having described my improvements, what I claim is In a feed-water heater, the combination with a boiler and a feed-Water heater located in effective proximity to the fire-chamber of the boiler, of a shell provided with an interior 'Ico tube, an' inverted conical valve within the just below the water-1ine,substantiall y as set IO valve-seat, means upon the exterior of the forth. casing for adjusting the valve, whereby the In testimony whereof I affiX my signature water injected into the shell creates a circuin presence of two Witnesses.
lation and draws into the shell a sufficient quantity of hot water from the boiler to ini- CHARLES HUTOHINSON' tially heat the feed-water before it enters the Witnesses: feed-water heater, and a return-pipe leading J. B. THURSTON,
from the upper part of the heater to the boiler GEORGE A. WAGNER.
