UNITED STATES EBENEZER BLAOKMAN, OF BROOKLYN, NEW YORK.

STOVE.

SPECIFICATION forming part of Letters Patent No. 236,665, dated January 18,1881.

Application filed April 6,1880.

To all whom it may concern:

Be it known that I, EBENEZER BLACKMAN, of Brooklyn, in Kings county, and State of New York, have invented certain new and useful Improvements in Stoves, of which the following is a specification.

My improvements relate to small stoves of the kind which are used for utilizing oil or gas as fuel.

The object of the improvements is to provide astove which may readily be altered so as to burn either oil or ordinaryilluminating-gas, such as is supplied to houses in large towns and in cities.

To this end one of my improvements consists in the combination, in a stove, of a wicktube of annular or hollow form, a cap therefor, a burner suitable for the combustion of gas, and a pipe or conduit for the gas to said burner.

Another improvement consists in the combination, in a stove, of a wick-tube of annular or hollow form, a cap fitting over and closing the tip of the same, a tube extending through the same into the inner shell of the wick-tube, a burner suitable for the combustion of gas communicating with said tube, and a pipe or conduit for conducting gas to said tube.

Another of myimprovements consists in the combination, in a stove, of a wick-tube of annular or hollow form, having its inner wall open at the bottom, a cap for said wick-tube, a burner suitable for the combustion of gas, a tube communicating with said burner extending down inside the inner shell of said wicktube and open at the bottom, and a pipe or conduit for conveying gas to said tube.

In the accompanying drawings I have illustrated my improvements in connection witha stove for which were granted to me Letters Patent of the United States numbered 197,318, dated November 20, 1877, and 203,994, dated May 21, 1878. Though I prefer using my present improvements in connectionwith this stove,

I do not restrict saidimprovements to use therewith.

In the drawings, Figure 1 is a central vertical section of a stove and appurtenances embodying my present improvements. Fig.

2 is a horizontal section thereof, and Fig. 3 is a horizontal section of the heating-drum of such stove.

(No model.)

Similar letters of reference designate corresponding parts in all the figures.

A designates an oil-reservoir supported on legs a, so as to have an air-space belowit; and B designates a wick-tube of annular form, composed of two shells arranged one concentrically within the other, and receiving and holding an annular wick, 0, between them. The outer shell of this wick-tube extends only to the top of the reservoir, but the inner shell extends to the bottom of the reservoir, and there provision is afforded by it for the free passage of air through it from below the reservoir to the point of combustion.

The Wick C may be adjusted by means of spring-jaws D, which embrace the wick inside the reservoir, and may be raised or lowered by means of a screw, E, which engages with a stock, from which they extend, and is accessible at the top of the reservoir. A spreader, F, consisting of a flattened bar accessible from the top of the reservoir and fitting between the free ends of the jaws D, provides for opening them and holding them open to allow of the raising or lowering of thejaws independently of the wick, to take a new hold thereof in a different position. A deflector, G, contracted upward towards the tip of the wick-tube and open at the bottom, directs air to the outside of the tip of the wick, and a deflector, H, arranged within the wick-tube and flaring outwardly toward the tip thereof, directs air to the inside of the tip of the wick.

I designates a combustion-chamber arranged just above the tip of the wick, wherein the flame from the wick .is maintained. Preferably the sides of this chamber are provided with transparent panels or windows, I), through which the flame may be seen to ascertain its condition. Above this chamber is a supporting-flange, J, provided with an upturned rim, K, for supporting a superimposed article such, for instance, as a heating-drum, L, hereinafter to be described.

M designates a cap, which may be of sheet metal or other suitable material, which fits snugly over the tip of the Wick-tube, but preferably so that it may be easily placed upon or removed from the same.

N designates a tube, shown nearly as large as the inside of the wick-tube B, and having a perforated diaphragm at the top, but open at the bottom. It passes through the cap M, and may be aflixed to the same or loosely fitted in an opening therein.

0 designates a pipe leading from outside the reservoir A to near the bottom of the wicktube 13, and having an outlet-aperture, c, opposite and near to the bottom of said wicktube. This pipe may be connected, by a flexible rubber tube or 0th erwise,with a gas-fixture, so as to conduct gas therefrom to the tube N. The tube N is surmounted by aflange, N, (shown as flaring outward,) and fitted to the diaphragm is a cap or deflector, which flares outward and upward into close proximity with the top of said flange, and leaving a constricted annular space between it and said flange, whence a film of gas may issue and burn. These devices in effect constitute a gas-burner.

I desire it to be distinctly understood that the cap M and tube N may be readily removed from the wick-tube when the latter is to be used, and may be as readily replaced when gas is to be used.

P designates an extension from the flange J, containing a passage or flue, Q, extending from said flange outward, a return passage or flue, Q, extending below the former to near the chamber I, and a passage or flue, Q extending from the said passage or flue Q outward again .to an outlet, Q. A removable cover is placed over the top of the rim Kin lieu of the drum L, and the products of combustion, leaving the combustion-chamber I, pass outward through the flue Q, thence inward through the flue Q close to the flame, whereby they are reheated, thence outward again through the flue Q and out of the outlet Q Vessels or articles to be heated may be arranged on the extension P or in apot-hole, l fitted with a removable cover therein, as well as over the rim K, and the products 0t @0111,

bustion, pursuing a devious course through the flues Q, Q, and Q are not only made to act Very efl'ect-ively in heating, but, by being reheated while passing in close proximity to the flame, have their combustible ingredients consumed, and before their escape are rid of noxious odors. The outer end of this extension may be supported on a stand or leg, R, to afford it stability.

When the stove is to be used for heating an apartment the drum is mounted on the flange J, and the products of combustion ascend through the interior of the drum, pass thence downward through an external passage or flue,

L, ascend thence through an external passage or flue, L and pass thence down through an external passage or flue, L escaping from the lower end thereof into the atmosphere. In passing from the flue L into the flue L the products of combustion are brought into close proximity to the flame, and being reheated are rid of noxious odors, so that when they escape from the drum they do not cause unpleasantness.

The flues L L L are formed by cylindrical casings S S S which surround the drum L, one outside the other, and it will be seen that the casing S, which separates the flue L from the flue L extends nearly to the bottom of the space between the drum L and the casing S, and that, therefore, the heated air is carried down under the lower edge of the casing Sand in contact with the heated bottom of the drum, whereby a higher degree of heat of the air is attained.

The drum L may be made of sheet metal, and will, owing to its large heating-surface, effectively utilize the heat evolved in the stove. It may be readily removed from the stove at will.

It will be seen that by my invention I produce a stove which may he used for oil or gas at pleasure.-

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

1. The combination, in a stove, of a wicktube of annular or hollow form, a cap therefor, a burner suitable for the combustion of gas, and a pipe or conduit for gas to the burner, substantially as specified.

2. The combination, in a stove, of a wicktube of annular or hollow form, a cap fitting over and inclosing the tip of the same, a tube extending through the same into the inner shell of the wick-tube, a burner suitable for the combustion of gas communicating with said tube, and a pipe or conduit for conducting gas to said tube, substantially as specified.

3. The combination, in a stove, of a wicktube of annular or hollow form, having its inner wall open at the bottom, a cap for said wick-tube, a burner suitable for the combustion of gas, and a tube communicating with the said burner extending down inside the inner shell of the wick-tube and open at the bottom, and a pipe or conduit for conveying gas to said tube, substantially as specified.
