0. CROSBY. STEAM BOILER (No Model.)
No. 482,787. Patented Sept. .20, 1892.
: Noam Wrens C04, Him-LUNG \wsnmcrrou n c UNITED STATES PATIENT OFF CE.
OLIVER CROSBY, OF ST. PAUL, MINNESOTA.
STEAM-BOILER.
SPECIFICATION forming part of Letters Eatent No. 482,787, dated September 20, 1892.
Application filed December 29, 1891- Serial No. 416,407- (No model.)
To all whom it may concern:
Be it known that I, OLIVER ORosBY, of St. Paul, Ramsey county, Minnesota, have invented certain Improvements in Steam-Boilers, of which the following is a specification.
My invention relates to improvements in that class of upright boilers which are provided with a water-chamber surrounding and protecting the upper ends of the flues, its 0b- 16013 being to provide means whereby said water-chamber is kept supplied with an amplequantity of water to compensate for evaporation without the use of a continuously-runnmg pump.
To this end my invention consist-s in extending the outer shell of the boiler a considerable distance above the top of the boiler proper or upper flue-sheet and in arranging in connection with the upper flue-sheet an innor shell above the same, connected to the top of the shell extension, thus forming an annular chamber or reservoir connecting with the water-chamber beneath the flue-sheet.
This reservoir or extension of the water-chamber should be of such capacity that it will compensate for the evaporation in the waterchamber and require filling no oftener than the boiler itself is supplied.
I am aware of the patent-to Waterou's, No. 400,529, issued April 2, 1889, which shows a water-chamber inclosin g the upper ends of the flues, and I do not claim this as any part of my invention.
My invention further consists in the construction and combination hereinafter described, and particularly pointed out in the claims.
In the accompanying drawings, forming part of this specification, Figure 1 represents a central vertical section of my improved boiler, and Fig. 2 is a similar section of a modified construction.
In the drawings, 2 represents the shell of the boiler, provided in the usual manner with the grate 4, the water-leg 0, the tines S, and steam-pipe 10, the shell 2 being provided with an extension 12 above the upper flue-sheet 14. The upper ends of the flues 8 are protected by means of a water-chamber 16, surrounding and inclosing the same, formed by the fluesheet, and a diaphragm 18, arranged a short distance below it. The flue-sheet is preferably of smaller diameter than the shell 2, and its edge is connected to an inner shell 22, which is carried upward and outward to connect with the top of the extension 12, thus forming an annular reservoir or extension 24 of the chamber 16. Preferably at the top of this reservoir connects the pipe 26, leading to the pump, and also communicating with the reservoir 24 near its top is an overflow-pipe 28, carried, preferably, downward outside the shell 22 and communicating with the waterleg beneath the crown-sheet 30.
In the modified construction shown in Fig. 2 the shell of the boiler is not carried above the flue-sheet; but a reservoir 32 is constructed above the chamber 36, formed by the flue-sheet 37 and diaphragm 18, communicating therewith by means of a pipe 34, the overflow-pipe 38 being arranged within the pipe 34, extending to the top of the reservoir and downward within the boiler nearly to the crown-sheet 30.
In use, the water-chamber and reservoir being filled with water, the heat from the flues gradually evaporates the water in the chamher, the steam passing off through the overflow or outlet pipe, which also carries off any surplus water when the chamber and reservoir are being filled. The water in the reservoir thus supplies the place of that evaporated from the chamber, so that the water in the chamber is always kept in contact with the flue-sheet 14: and the connections of the fines therewith without necessitating the continuous working of the pump.
I c'laim 1. In a steam-boiler, the combination, with the flues thereof and a water-chamber surrounding andinclosingthe upper ends of the flues, of a reservoir located above and communicating with said chamber, having suitable outlet at or near its top and adapted to replenish-said chamber automatically, substantially as described.
2. In a boiler, the combination, with a waterchamber surrounding the ends of the flues, of a reservoir connected with said chamber, the outer walls of which are formed by an extension of the boiler-shell, adapted to keep said chamber at all times filled, substantially as described.
3. In an upright boiler, the combination,
with the water-chamber surrounding and inclosing the upper ends of its flnes, of an annular reservoir or extension to said chamber above the same, adapted to keep said chamber supplied with water, and an outlet-pipe communicating with said reservoir at or near its top, substantially as described.
4. The combination, with the shell of an upright boiler, of an upper extension thereof, the flue-sheet, the inner shellconnected'at its lower end to the fine-sheet and at its upper end with the top of said extension, the diaphragm arranged beneath said flue-sheet, constituting a water-chamber surrounding the upper ends of the fines, and a storage-reservoir therefor, and an outlet-pipe communicating with the space between the inner shell and the extension at or near their junction, snbstantiall y as described.
5. In an upright steam-boiler, the combinafines and forming a water-chamber, an upper extension of the boiler-shell, a concentric inner shell connected at its lower end to the edge of the fine-sheet and at its upper end to the shell extension, forming a reservoir for said chamber, an inlet-pipe for said chamber, and an outlet-pipe for said reservoir communicating with it near its top, substantially as described.
OLIVER CROSBY. In presence of- T. D. MERWIN, A. M. WALCH.
