SAFETY OIL-CAN ATTACHMENT FOR VAPOR-STOVES.-

SPECIFICATION forming part of Letters Patent No. 404,439, dated June 4, 1889.

Application filedDecember 24,1888. Serial No. 294,466. (No model.)

To all whom it may concern.-

Be it known that I, HENRY RUPPEL, a resident of Cleveland, in the county of Cuyahoga and State of Ohio, a citizen of the United States, have invented a certain new and useful Improvement in Safety Oil-Can Attachments for Vapor-Stoves; and I do hereby declare the following to be a full, clear, and complete description thereof.

The nature of my invention relates to certain means for the purpose of shutting off oil or gasoline from the generator and needlevalve when the oil can or tank is lowered for filling, and raised to its former position to supply the burner when filled, whereby explosion and danger from the overflow of oil is prevented.

In the use of this improvement the oil is not cutoff from the stand-pipe, but is arrested therein and prevented from passing therefrom to the generator heating-tubes or needlevalves when the oil-tank is returned from its lowered position to an upright one. A secondary movement or action is also required to open the valve in the stand-pipe to allow the oil to flow therefrom to the generator. In supplying the stove with oil the tank is lowered, and by this movement a valve closes the passage from the stand-pipe to the generators, thereby extinguishing the burner, but not discharging-the oil from the stand-pipe; hence on raisingthe oil-tank the oil will not flow into the generators or through the needle-valve if open, thus preventing an overflow of the burner and protecting the person lighting the stove from the danger of the explosion or burning of the overflowed oil or gasoline. This overflow of oil will occur in the ordinary drop-tank mechanism if the needle valve or valves are not securely closed. In lighting a stove of this kind there is a delay directly after the tank has been filled and raised, as the stand-pipe must be first filled from the tank before the generator can be put in operation. In contradistinction to this, with my improvement the oil in the stand-pipe is not discharged therefrom, but is cut off by means of a valve from flowing into the generator and needle-valves when the tank is lowered for filling. On raising the tank the said valve (which is between the stand-pipe and generator) remains closed until opened by a secondary movement, as may be required in lighting the stove, whether it is or not to be lighted immediately, which then will permit the passage of oil from the standpipe to the generator. The operation of the valve for the admission of oil to the generator is resultant of a secondary independent agency, which may be more or less delayed after the tank is in its normal position.

Figure 1 is a sectional elevation of a vaporstove, Plate 1. Fig. 2 is a vertical section of the stand-pipe, heater-plate, and attachments. Fig. 3 is a detached section in linesoccof Fig. 2. Fig.4: is a sectionalview of certain mechanism employed in connection with parts involving the safety oil-feeding attachments, Plate 2.

Like letters of reference refer to like parts in the several views.

In Fig. 1 A represents the heater-plate; B, the vapor-pipe; C, the needle-valve chamber; D, the oil tank or can; E, a part of the stoveframe, and G a corrugated burner-cap having slit-openings through the corrugations to the interior. In the stand-pipe F is a valve H, having its seat in the valve-rod guide H, Fig. 2. The upper part of the valve-stem J is supported in position and moves in the guide H. The stand-pipe is screwed into the short tube of the heateuplate, as seen at I, Fig. 2. To the'lower end of the rodJ is adjustably attached the lever K. The lower part of the rod is provided with a stuffingbox L, to prevent leakage of oil from the stand pipe. The said rod is preferably threaded at M in the upper part of the stuffing-box, which is an extension from the lower end attachment of the T-shapedpipe N N, screwed to the terminal of the stand-pipeF, as seen in the drawings, Figs. 2 and 3 The valve-rod guide H is fitted in the interior of the short tube 0, projecting. from the heater-plate A, between the annular shoulder S and the upper end of the stand-pipe, as seen in Fig. 2. In the said guide I are one or more ports or openings P, through which the oil passes from the standpipe and valve H when open into the generator Q on the under side of the heater-plate A. The vapor from the generator extends through the pipe or conduit B to the needle-valve C, then through the air-tube R to the burner-cap G, Figs. 1 and 2. The tank-pipe D, which is in open relation or connection with the oil-conduit 0, Figs. 2 and 4-, extends down and turns in an angular direction to connect with the section N of the T-shaped fitting or pipe N N by being threaded into it, as seen at V, Fig. 4. The gland v of the stuffing-box V is screwed on the section N, Figs. 3 and 4, the pipe D passing through the said stuiiing-box, by means of which the connection of the jointed articulation of the pipe I) with the section N of the T-pipe is made oil-tigl'it, at the same time admitting the moving of the tank from D to D, and vice versa, as hereinafter more fully described.

Movably attached to the*pipe D is an arm \V, arranged to operate the lever K at the terminal of the valve-rod J, Figs. 2 and at. 011 moving the tank from D to D, or a given intermediate point, the arm W on the pipe D will so operate the lever K as to raise the valve-rod J by means of the screw M and close the valve II, which will prevent the inflow of oil from the stand-pipe and oil-tank to the generator Q, thereby extinguishing the burner. The position D of the tank does not admit of the withdrawal of the oil from the stand-pipe, as would be the case were the tank D lowered to the position D, as is required in ordinary drop-tank mechanism. On raising the tank from D to D the oil will flow from the tank through the pipe D up into the stand-pipe E and overflow the stove if a needle-valve is forgotten or from any cause left open; hence, on lighting a stove in such condition an explosion or a dangerous fire will ensue, involving the person attending it.

In the drop-tank arrangment as ordinarily used the tank is to be lowered to about the position D with the needlve-valves closed, this position causing the oil to flow down out of the stand-pipe F on a level with the oil in the tank at D. Now, the raising the tank from D to D causes the oil to pass up through the stand-pipe and out through the needle-valves if not perfectly closed, thus producing the overflow and the dangerous results before mentioned, which results are avoided by the use of myimprovement, as the tank is only moved from D to D, in which position the stand-pipe F is full of oil and on a level with the oil in the tank at D, which movement of the tank D to D closes the valve H and cuts oif the oil from the generator Q and needle-valve. The valve II remains closed after the tank is raised, which prevents the lighting of the stove until the operator so moves the lever K by t-hehandle K as to open the valve II, allowing the oil to flow from the stand-pipe into the generator Q, Figs. 2 and 4.

On lowering the tank D the valve II is closed to shut off the inflow of oil from the stand-pipe to the generator after the tank is moved back to its normal position. Then by a reverse motion of the valve-stem J, by means of the handle K, the valve II is opened for the inflow of oil to the generator from the stand-pipe in the manner described. However, this opening of the valve lI may be more or less delayed after the tank is raised. This secondary movement of the valve-rod for opening the valve is arrested by the contact of the lever K with the, arm IV until the tank D is up in position, as shown in Fig. 1.

As shown in Figs. 2 and 3, it is supposed that the valve II has been opened by the sec ondary movement of the handle K, which again sets the lever K in contact with the arm IV, whereas the dotted lines (I in Fig. 3 indicate the position of the lever K, into which it is turned when the tank is lowered for filling.

By means of the mechanism described the inflow of oil to the generator and needle-valve is effectually shut off and the burners extinguished on lowering the tank for refilling, or for other purposes, remaining cut. oil? until supplied, as described, by swii'iging the tank to its original position.

To relight the stove, the valve II must be first opened before any oil can be admitted to the generator, whether the needle-valve is opened or not, as the valve H controls the supply of liquid fuel to the burner as maybe required, with or without the use of the vapor or plug valve at c.

The improvement herein described is shown in connection with one burner. The same arrangement of mechanism is, however, applicable to two or more burners without departing from the essential features of my invention. The pipe 1), Figs. 3 and 4, represent an attachment by which the said mechanism may be extended to other burners of the same stove. The lever K and arm WV are respectively so adjustable on the Valve-rod J and tank-pipe D as to be moved, set, and secured by the set-screws in the required position for opening and closing the valve II on moving the tank D, as and for the purpose described.

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