IIV'PROVEMENTIN FUflRNACES.
Specification forming part of Lettzrs Patent No. 148,361, dated March 10, 1874; application filed January 10, 1874.
To all whom it may conccr'n:
Be it known that I, JOHN GOULDING, .of Worcester, in the county of Worcester, State of Massachusetts, have invented a certain new and useful Improvement in Furnaces, of which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which my invention appertains to make and use the same, reference being had to the aceompanying drawing forming a part of this specification, in which- Figure 1 is a vertical section of my improved generator. Fig. 2 is a side elevation of the same with a Sectional view of the diaphragm. Fig. 3 is a Sectional view of the boiler.
Like letters refer to like parts in the different figures of the drawing.
My invention relates more particularly to that class of generators in which gas, generated from a hydrocarbon-oil, or-other volatile liquid, is used as the motive power; and consists in a mechanism for automatically controlling and regulating the heat used in generating such gas, as hereinafter more fully set forth, the' object being to render generators of this description less liable to explosion, and, consequently, safer than they have heretofore been.
In Fig. 1, A is the furnace, provided with the usual door M, register or draft V, grate B, and with the safety-funnel G. Within the furnaee A there is a eoncal diaphragm or petticoat, C, and a diaphragm,.E, extendin g laterally entirely across the interior or cavity of said furnace. 'These diaphragms are each provided with a central opening, and are connected by the vertical funnel or fiue D, from which the horizontal safety-funnel G opens outwardly, as shown. H is the tank or boiler for containing the oil or other liquid, and is provided with the flues I I. Within the vertical funnel or flue D, there is a deflector or damper, F, disposed on the crank-shaft T, Fig. 2. This'shaft is connected by the link S with the long arm of the damper-lever J, 'which lever is pivoted to the stud K projecting from the boiler A. rThere is a chamber or tube, L, connected by the pipe P with the boiler or tank H. Across the top of this chamber a rubber diaphragin or valve is secured, on which the lever J rests, as shown in Fig. 2, said lever J, diaphragni It, chamber L, and pipe P, constitut-ing what I denominate a valve mechanism.
From the foregoing description the nature and operation of my invention'will be readily understood by all conversant with suchV matters. i
The boiler H being properly supplied through the inlet-pipe N with the liquid to be used, and a fire started on the grate B in the furnace A, the products of combustion will pass upwardly through the funnel D and flues I I, imparting their heat to the contents of the boiler H, and thence out of the apparatus into any convenient chim'ney or funnel to be provided for that purpose. By this means gas or steam, as the case may be, will be generated in the boiler, and will pass through the pipe P and fill the chamber L, exerting the same pressure on the rubber diaphragm It, which is e exerted within the boiler H. The diaphragm will thus be extended or expanded, and, acting upwardly against the lever J, will, ,through the link S and crank-shaft T, operate the damper or deflector F, and thus close, or partially close, the funnel D.
It Will be seen that, as the valve F is thus operated, the heat will be wholly or partially shut ofi' from passing through the funnel D and flues I I, and will pass out of the safety-funnel G instead. For instance, in case the pressure in the boiler H is great enough to raise the lever .J sufficiently to entirely close the damper F, all of the heat will then pass out of the furnace through the funnel G. Heat being thus deflected or withdrawnfrom the boiler H, and, at the same time, gas or steam being taken from the engine for use in the Ordinary manner, the pressure within the boiler will be gradually reduced, allowing the lever J to fall and partially open the damper F, which will again permit the heat to ascend through the fluesI I and generate a furthersupply of steam or gas, thus operating automatically to supply the boiler with a uniform degree or quantity of heat. I sometimes connect the lever J with the door M and register V, in such a manne'r as to open said door, and at the same time close the register, thus lessening the draft through the fuel when necessary, and preventing a waste of the same. A piston properly packed may also be used in the chamber L, to
nact against the lever J in place of the rubber in a position to close the funnel G, as shownV in Fig. 1.
My invention is more especially applicable to gas generators, but is equally valuable in certain kinds of steamengines, and I do not therefore confine myself to its use in either connection.
I am aware that engines have been used in Which the steam or gas in the boiler has been applied to regulate the draft of the furnace by opening and closing the draft-registers to an extent varying in accordance With the press ure of such steam or gas, but the objection to such an arrangement is, that, after the draftz register is entirely closed, considerable time Will elapse before the heat supplied to the boiler Will be materially reduced, whereas, in my improved generator, by turning aside or defiecting the volume of heat,ias described, the generation of gas or steam in the boiler is at once lessened, and all danger of explosion obviated. I, therefore, do not herein claim a mechanism for operating the' draft-register of a generator, as described, When in and of itself considered; but
What I do claim is-- 1. In combination With the furnace of a generator, such as described, a mechanism operating automatically to deflect or turn away the heat and products of combustion from the boiler, substantially in the manner and for the purpose specified.
2. The furnace A, diaphragm E, damper F, flue D, diaphragm O, and safety-funnel G, in combination With a Valve mechanism connected With the boiler for operating said damper, substantially as and for the purpose specified.
JOHN GOULDING.
