HENRY RUPPEL, OF CLEVELAND, OHIO, ASSIGNOR TO THE DANGLER STOVE AND MANUFACTURING COMPANY.

TANK FOR GASOLINE4 OR VAPOR STOVES.

SPECIFICATION forming part of Letters Patent N0. 497,896, dated May 23, 1893.

Application filed July 7, 1892. Serial No.439,204. (No model.) l

To all whom it may concern/.-

Be it known that l, HENRY RUPPEL, a citizen of the United States, residing at Clevedisk and the bottom of the said inner tank being provided with a collar to which is attached a plug and a spring actuated valve.4

\ The object of my invention is to provide a tank so constructed and arranged as to reguf `late and govern the supply of oil to theburner safety in case of accident, as when a stove is and also to prevent explosion and insure upset, by cutting o at once the ow of oil and confining the same to the inner tank.

1 y y That my invention `may be seen and fully understood by others, reference will be had to the following specification and annexed `drawings forming a part thereof.

burner.

Figure lis a vertical section of the two U tanks connected; Fig. 2 a vertical section ot so the tanks disconnected; Fig. 3, a smaller horizontal section ot' the outside tank above the false bottom; Fig. 4, a full size view ot the plug and valve, showing the method by which the valve stem is held in place. Fig. 5, represents a small stove or heater, with my tank attached thereto, and connected with the Fig. 6, is a partial View of a gasoline cook stove with my tank attached thereto and connected with the burner.

Similar letters of reference designate like y parts in the drawings and specification.

The outer tank A is provided with the false bottom B Figs. l, 2, and 3 forming a tight joint With said tank. The opening B', is centrally located in the false bottom B and is closed in Fig. 2, by the concavo-convex disk C, which is attached to the upper part of the tube D. l In the disk C is the opening Ccorresponding in size to the inner diameter ot' the tube D. The tube D Figs. l, 2 and 3 tits closely over the tube E, which is secured to the bot- .,tom of the tank A, and has at its base the openings E. `The spiral spring FFigs. l and 2 encircling the tubes D and E and bearing at its base Aupon the bottom of the tank A, and at its top onthe under or concave surface of the disk C, forces said disk tightly against the false bottom B, when there is no preponderance of pressure from above, as shown in Fig. 2, thereby closing the opening B.

The pin Gr, Figs. l, 2 and 3 is held rigidly in the center of the tube E by the small pins G.

In the center of the bottom of the tank A, is an opening to receive the pipe H, which carries the gasoline to the burner.

The tank A is provided with the cover A', and the spring I Figs. l, 2, which prevents the cover A from being opened more than is sufficient to remove or replace the inner tank and as will be seen in Fig. 2. the cover must always drop into place overthe top of said tank by its own weight unless otherwise held up. The cover A has the handle A2, with which to raise said cover.

In the drawings the false bottom B has on its upper surface, an annular ridge a. Fig. 3 surrounding the opening B and the ribs b Figs. 1, 2, and 3 radiating from the ridge a. to the outer circumference of the false bottom.

In the side of the tank A and a little below the false bottom B is the small opening J. Figs. 1 and 2. through which air is admitted after passing in at the top of the tube J', said tube extending from below the opening J. onthe outside of the tank A to within a short distance of the top of said tank.

The heaviest part of a gasoline stove is the back, and a stove when upset generally falls backward. For this reason the tube J is placed preferably on the front of the tank so that no oil will escape through it in case of accident.

The inner tank K Figs. 1 and 2 has a closed top Which is provided with the handle K for raising the inner tank out of the outer one, or lowering it into the same.

Within a central opening in the bottom ot' the tank K is secured the collar L Figs. l and 2, the lower part of which is screw threaded on the inside, to receive the plug M which forms atight joint with the nozzle Lby means of the washer N. At intervals around the base of the plug M are the knobs M', for the purpose hereinafter described.

The plug M is provided with a valve open- ICO forces the valve upon the seat M2, as in Fig. 2

when there is no pressure from below. upon said valve; thereby completely closing the valve opening O, thus cutting off the flow of gasoline from th'e tank K.

In operation, the tank K, having been filled with oil is lowered into, the tank .A until the knobs M', come in con-tact with, the upper or convex surface of the disk C and the top of the pin G strikes against the base of the.

valve P, when the Weight of the tank K and its contents forces the disk C, and tube D, down until the tank K rests upon the false bottom.; at the same time the valve P is opened by the pin G, when the several parts will appearas shown in Fig. 1. of this condition of the parts is, that the iiuid in the tank K, iiows through the opening O in the plug M and out through the interstices yformed by the plugM, knobs M and thedisk C into the space .below the false bottom B, filling the same as high as thedotted lines fr Fig. 1. Since air is admitted below the false bottom through the tube .I' and the opening J, the liability of explosion of the fluid con tained inthe tank is reduced to a minimum by preventing the liquid from rising'above the lines at, H through the openings E', in the tube E and is thence conveyed to the burner. p More or less of the oil will flow directly into the pipe H through the tube E. When the tank K is empty and it is lifted out or in case the stove, to which it is attached is overturned accidentally, as often happens, and the two tanks become disconnected, the spring R will close the valve P, thus cutting olf the supply of oil from the tank A, and the spring F will raise the disk C` into place; thereby closing the opening B', in the false bottom B through which the plug and collar were obliged to pass.

The herein described tank may be used in connection with the burner S, Fig. 5 to heat a small stove or heater T, or it lmay be used in connection with the burner S'.Fig. 6 in the cook stove T' The ilow of oil from the tank to the burner S or S' through the pipe U or VU' is controlled by a valve V, said valve beingprovided with the safety latch W Figs. 5 and 6. A partition of asbestus Y Figs. 5 and 6 separates the tank from the stove to prevent the generation of gas, by reason of the contents of said tank becoming heated. Any

other non-conductor of heat may be used as a substitute for asbestus. The pin G Figs.

The result l, 2 and 3 may be omitted and the tube E lengthened sufficiently to perform the oice of said pin, in raising the Valve P. When the tank K is removed from the outer tank to be refilled, it is reversed and the plug with Athe several parts attached thereto, is unanv inner tank 'having a collar attached to the botto-m thereof, interiorly screw threaded at its lower part to receive a plug, said plug 4being provided with knobs M', and having an annular opening closed by a spring actuated valve, held in place by a valve-stem supported, by the guide Q, in combination with an outer tank vhaving a false bottom provided with a central opening closed by a spring actuated disk in vconnection with the tube D, outside of the tube E, said tube E having lateral openings in the base and a pin G, attached thereto in the manner substantially as and for the purpose set forth.

2. In a tank for gasoline or vapor stoves, an inner tank having a collar, plug and spring actuated valve attached to the bottom thereof in combination with an outer tank having a false bottom, with a central opening closedy by a spring actuated disk, a tube E, and pipe Il, thecover and spring I in the manner substantially kas and for the purpose set forth. The oil now runs into the pipe y closed by a spring actuated valve in the man! ner substantially as and for the purpose set forth.

4. In a tank for gasoline or vapor stoves, an outer tank incased in a non-heat-conducting substance and having a false bottom provided withacentral openingclosed bya springactuated disk, the tube D, perforated tube E, pin Gr and the pipe J', in combination with an inner tank having a collar and plug attached to the bottom thereof, said plug being provided with an annular opening closed by a spring-actuated. valve, in the manner substantially as and for the purpose set forth.

In testimony whereof I afx my signatu re in presence of two witnesses.
