VAPO R-STOVE.

SPECIFICATION forming part of Letters Patent No. 554,207, dated February 4, 1896.

Application filed March 14, 1895.

To all whom it may concern:

.Be it known that 1, WILLIAM H. Woonnnn, of Cleveland, in the county of Ouyahoga and State of Ohio, have invented a new and useful Improvement in Vapor-Stoves, of which the following is a specification.

My invention consists in an improvement in vapor-stoves, hereinafter fully described and claimed.

Figure 1 is an elevation partly in section. Fig. 2 is an elevation of the carburetingburner, showing a switch to control. the admission of air; and Fig. 3 illustrates a slight modification of the oarbureting apparatus.

In vapor-stoves as now constructed gasoline is contained in an elevated tank T, whence it flows down through a pipe A and the horizontal pipe V, up through a stand-pipe G into a retort D, upon which is placed a burner E, and from said retort the vapor goes down through a pipe P out through a needle-valve R, this passage being controlled by two valves I II or by the valve H alone, then through a, combining-tube or mixer, where the vapor is mixed with air, and finally burns at the burner E. The connection between pipes A and V is commonly made through a swivel-joint B, by which the tank T is turned down for filling, so as to prevent said tank from being filled while the stove is burning. All the parts described up to this point are old and in common use and not of my invention, except that the lay-down tank was invented and patented jointly by Charles F. Klein and myself.

The main objection to stoves of this class is that in order to light them the retort D must be heated in order to vaporize the gasoline therein contained, and this is usually done by drawing a little liquid gasoline into a cup surrounding the needle-valve R, then lighting said gasoline, and heating the retort by the flame thus produced, which operation causes considerable smoke and smell and is objectionable. My invention is designed to obviate this objection; and it consists broadly in the connection with a gasoline-stove of a carburetor by which a gas-flame may be obtained when the stove is cold in order to heat the retort.

Of course a carburetor may be made in a great many different ways, and I have illustrated one way which I deem is a good one,

Serial No. 5 ll,'72l. (No model.)

and perhaps the simplest and best one that can be devised.

J represents a hollow vessel whose bottom is connected with pipe V, and at the point of connection I prefer to place a valve K, by which communication from pipe V to vessel J may be controlled.

0 represents a removable plug in the upper part of vessel J.

L represents a pipe leading from the upper part of vessel J to a secondary or Bunsen burner G, placed under the retort D and provided with a valve S.

g represents a valve mounted to turn on the tube G and having openings adapted to register with openings 0, whereby air may be admitted through said openings or out off therefrom. The valve g is simply a piece of sheet metal bound around the tube G and capable of turning thereon. One end of the valve 9 may be left projecting or a single ring may be used.

The operation of my invention is as follows: If the tank T be swung down and valve S be opened, or plug 0 be removed, valve K being open, all gasoline in pipe Vand in vessel J is drawn out and vessel J becomes filled with air. If now valve S be closed and tank T thrown up to its illustrated position, gasoline flows down through pipes A and V and flows through valve K into the interior of vessel J, coming in contact with the air therein, and as gasoline is quite volatile at ordinary temperature the air in vessel J becomes carbureted, so that when valve S is opened and a light applied to the top of the burner-tube G a gas-flame is at once obtained under the retort D, which heats said retort to vaporize the gasoline therein contained, and the pressure of gasoline on the under side of the air in vessel J maintains this flame for a length of time, depending upon the size of the vessel J. As soon as retort D is sufficiently heated to vaporize the gasoline therein contained,valvestem II of needle-valve R can be operated to open the needle-valve, and the flame lighted at the burner E in the usual manner, and as soon as this is done valve K should be closed to prevent access of gasoline to vessel J.

It may be often desirable to increase the carbureting power of vessel J, and this may be readily accomplished by putting in said vessel some fabric to be moistened by and retain gasoline, so that when air enters said vessel there will be sufficient gasoline or gasoline-vapor to carburet it. One way to do this is to insert in said vessel J a wire frame N covered with cloth or loosely-woven asbestos, or other suitable material, or to partlyfill said vessel with cotton, the arrangement which I have shown-a cylindrical wire frame N covered with clothbein g perhaps as simple and as eflicient as any.

Of course if it is desired, gasoline may be allowed to flow through pipe L if it rises to the height of said pipe in vessel J, and it will become vaporized in that part of said pipe which is near burner G, so that a flame may be kept at said burner continuously, and if this is done valve K must not be entirely closed; but when it is desired to use the apparatus only as a carbureting apparatus a float-valve u may be placed in vessel J, as indicated in Fig. 8, to close the end of pipe L, which permits air to pass when the gasoline is low in vessel J and closes the end of pipe L when the gasoline rises to the proper height.

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

1. In combination with a gasoline-stove having an elevated tank connected by means of a pipe with a retort for vaporizing gasoline, a carbureting-vessel attached to said pipe and provided with a valve controlling the communication between said vessel and pipe, and a gas-pipe leading from the top of said carburetingwessel to a valve-controlled burner in proximity to said retort, substantially as and for the purposes set forth.

2. In combination with a gasoline-stove having an elevated tank, and a pipe connecting said tank with a vaporizing-retort inter mediate between the tank and the needlevalve, a carbureting-vessel having its bottom connected with said piping and having a valve controlling the communication between said pipe and carbureting-vcssel, material adapted to retain a small amount of gasoline in said carbureting-vessel when the liquid gasoline is drawn off therefrom, means for admitting air to said carbureting-vessel when gasoline is drawn oil therefrom, and a burner in proximity to said retort connected with said carburetingvessel, substantially as and for the purposes set forth.

3. The combination with a retort havinga burner, an d an elevated gasoline-tank having a pipe connection with the retort, of a carburetor connected to and communicating with the pipe connection between the elevated tank and the retort, a secondary burner arranged in juxtaposition to the retort and having a pipe connection with the carburetor, and a float-valve arranged in the carburetor and serving to control communication between the latter and the pipe connection with the secondary burner, substantially as described.

4. The combination with a retort having a burner, and an elevated gasoline-tank having a pipe connection with the retort, of a carburetor connected to and communicating with the pipe connection between the elevated tank and the retort, a Bunsen burner arranged in juxtaposition to the retort, having a pipe connection with the carburetor and provided with a valve for governing the admission of air to said Bunsen burner, and a float-valve arranged in the carburetor and serving to control communication between the latter and the pipe connection with the Bunsen burner, substantially as described.

5. In a gasoline-stove the combination with an elevated gasoline supply-tank and a supply-pipe extending vertically from said pipe and horizontally under the burner and having therein a swivel-joint for swinging said tank downward, of a carburetor connected with the horizontal part of the supply-pipe and having a burner in proximity to a retort on the stove, substantially as and for the purposes set forth.
