To all whom t meg/concern:

Be it known that l, GEORGE H. li"E\RaIs,of1V

Brooklyn, KingsV county, and State of New York, have invented certain new and useful Improvements in Lamp-Stoves, ofwhichthe following is a specification.; i

These improvements areV embodied in a lamp-stove, wherein isa cast-metal base-piece connected by a hinge or articulation with the lamp-reservoir, and provided with legs for resting thereon, flues erected on the base-piece and supporting a combustion-chamber, which is closed save where it affords ingress and egress f'or the products of combustion,a and a bolt securing the base-piece, fines, and combustion -chamben together, whereby a very strong, economical, and otherwise superior article is produced.

The accompanying drawing .illustrates an oil-lamp stove embodying my improvements. Figure l is a central vertical section of such stove, and Fig. 2 is a plan thereof.

Similar letters of' reference designate correspending parts in both figures.

-A designates an oil-reservoir, shown as of cylindrical form, and may be erected on legs or feet a. It is provided with lamps consisting of wick-tubes B, wick-adjusting mechanism, and inclosing-shell b. It is also provided with a mouth or orifice, G, and is shown as being so constructed that its upper part may serve as a water-chamber, D. E designates a base-piece,which may,with advantage, be made of' cast metal, and is provided with the part c of a hinge, c c', connecting it to the oil-res; ervoir A, and with legs d, adapted tov-rest upon the top edge of the said oil-reservoir, or of that part which forms the water-chamber D. Between the oil-reservoir and its appurtenances and the base-piece E ample provision f'or the passage of' air to the lamps is afforded. Air-distributers G, consisting ofl a plate of foraminated or reticulated material supported upon the lamp wick-tubes immediately under the base-piece E,and bracingand strengthening them laterally, or in lieu thereof, or in addition thereto, air-distributers H, consisting of cylinders or shells of foraminated or reticulated material surrounding the lamp wick-tubes, may be employed.-`v I designates the deiectors,

which, as represented, are embodied in thev extinguishing the flame.

base-piece E, and may, with advantage, be so constructed, because then provision will be a'orded, whenl the base-piece is 'swung back, for trimming and lighting the wick as well as J designates fines, (here shown as two in number,) supported on the base-piece E over the deflectors, and extending upward therefrom, so as to induce proper drafts of air to insure a perfect combustion of' oil in the lamps. K designates a combustion-chamber, which is represented as made of' cast metal,l and is entirely closed save where it aifords ingress and egress for the products of combustion ascending from the lamps; in other words, it is destitute of' any openings whatsoever except those through which it communicates with the lamps, and that at which it receives the articles to be heated. As here represented, it is supported solely by the iiues J, and communicates directly therewith, wherefore it is isolated from the lamps. I have indicated by dotted lines K that it may be of any desirable depth. It is preferably provided at the top edge with a series of' projections, e, for supporting articles which are larger than it in diameter, so that provision will be afforded for theescape of the products of combustion below them, and it is also preferably provided with other projeetions, f, for supporting smaller articles, so that they will not interfere with the escape of the products of combustion.

I have shown the iiues J as fitting tightly outside portions or lianges g g of' the basepiece E and combustion-chamber K, so that lap-joints are formed, and all these parts are braced laterally1 together, so as to be rendered very strong and stable. A bolt, L, passing through the base-piece and the combustionchamber, fastens them together with the flues between them, and form one rigid structure, which may be swung back at pleasure to afford facility for lighting, trimming, extinguishing, and replenishing the lamps.

The isolated closed combustion -chamber supported by the closed iiues possesses great advantages. The lines, by confining the products of' combustion, induce strong drafts of air to the lamps and invigorate the combustion, while the combustion-chamber allows them to expand in volume and circulate slowly therein about the bottom of the article to be heated, so as to be most available, and then to pass upward around the sides of the article to be heated, wherefore they are most thoroughly utilized.

As I dispense with a drum in this stove I produce a very cheap and extremely strong and durable article, wherein great economy of oil is attained, and with so perfect a combustion that the emission of noxious vapors is obviated.

To render the stove more convenient it may be constructed so that it can be lighted without altering its position, and may be provided with devices capable of being moved wholly over the lamps to extinguish them, or partly over them, so as to reduce the size of the llames and the heat arising therefrom, without turning down the Wick, impairing combustion, and entailing the emission of vapors.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination, in a lamp-stove, of a base-piece, E, with legs d and hinge c, supported on a lamp, and a combustion-chamber adapted to support articles to be heated, with iues interposed between the base-piece and the combustion-chamber, substantially as described.

2. In a lamp-stove, a cast-metal bottom piece, E, provided with part of a hinge or articulation, and legs d, adapted to be supported on the lamp-reservoir, and to support the flues of the stove, substantially as set forth.

3. The combination of the base-piece E, provided with legs d and hinge c, iiange g thereof, iues J, combustionchamber K, flanges g thereof, and bolt L, substantially as and for the purpose set forth.
