VAPOR-LAMP.

Specification of Letters Patent.

Patented Jan. 16, 1906.

Application filed September 22, 1904. Serial No, 225,517.

To all whom, it may concern:

Be it known that I, EDWARD SEITZ, a citizen of the United States, residing at Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Vapor-Lamps and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to gasolene-vapor lamps.

The object of the invention is the general improvement of such lamps.

A further and important object of the invention is the provision of automatic means, in connection with the needle-valve of a vapor-lamp, by which when the light is turned off a small vapor-jet may be directed against the generator of the lamp, which in burning keeps said generator hot and ready for instant use.

A further object of the present invention is the provision of a pilot-light for use in starting the light at any time and also for keeping the generator constantly heated, so said lamp may be turned up at any time to burn at its full capacity after having been turned oif-for instance, as during the day.

A further object of the invention is to provide simple and thoroughly-reliable means for instantly starting a vapor-lamp without the necessity of first generating the vapor.

In the accom anying drawings, forming a part of this app ication, Figure 1 is a side elevation of my improved lamp in part section. Fig. 2 is an elevation of a combustion-chamber, showing a valve in the top thereof. Fig.

3 is a horizontal section of a portion of the lamp, taken on line X X, Fig. 2. Fig. 4 is a top view of a flap-valve. Fig. 5 is a horizontal section of the generator and combustionchamber on line Y Y, Fig. 1.

Many lamps used for burning gasolene-vapor are not what may be termed self-lighting and must always be initially heatedby burning alcohol or gasolene beneath the generator, whereby vapor may be formed to start it, after which the heat from the mantle serves to constantly produce more vapor for the steady burning of the lamp. In view of the disadvantages found in such lamps I have devised the lamp shown in the drawings, in which A indicates the usual bracket or support for the glass globe B, the same bemg supported in suitable manner by means ward its top, where it receives a flap-valve F.

(Shown in Fig. 4.) The top of said chamber D is notched at diametrically opposite sides, as at G, within which the trunnions H of the said valve F rest. At one side of the chamber D and preferably cast therewith is the generator I, consisting of leg J with which at its lower end the gasolene-feed pipe K is connected, said pipe being either connected with an overhead tank or a tank under air-pressure, as desired. The upper end of J is closed and extends somewhat above the top of the chamber D and lies parallel with the mantle D common to all lamps of this character. Between chamber D and the portion J just described is a pipe L, opening at its top into the said member J, as shown, its lower end carrying a cup M and also a needle-valve casing N, whose orifice is beneath the chamber D and directed to enter vapor into the latter. The stem 0 of the said valve carries a disk P, with which engages a fork Q, carrying a rod R, the upper extremity having-pivotal connection with an arm S of the said flap-valve F, the lower end of the rod being guided in a lug N on the valve-body, as shown. The generator I is filled with asbestos or other good filtering matter not affected by heat, through which the gasolene passes from the pipe K to the valve N, as indicated by the arrows.

In starting the lamp when first installed alcohol or gasolene is poured into the cup M and ignited. The heat therefrom vaporizes the gasolene within the generator and the valve on being opened liberates the vapor under pressure, directing it upward into the chamber D, where it is burned at the mantle, as in all lamps. The heat from the mantle serves to heat the upper extension of the generator, thereby continually forming vapor. Now when it is desired to extinguish the light the needle-valve is turned, as usual, in a di rection to close it until it meets an arm T, pivoted on a lug U of a portion of the valve memberN described. This prevents the entire closing of the valve and permits a very small portion of the vapor to pass up into the chamber D. With this action the disk P by means of the fork Q, pushes the rod R upward, thereby pushing the arm S of the flap-valve upward also to throw the valve to a horizontal position, it having hitherto occupied an upright or vertical position, as shown by full lines in Fig. 2. It will be noted that the said arm S is set at an angle to the valve, so that a movement of the rod R in the direction of its length will accomplish the opening or closing movement freely, as shown by the broken and full lines in the figure last named. By

closing the top of the chamber D the vapor is confined, and-an outlet is provided in the wall of the chamber adjacent to the generator through an aperture V, slanted upward, the vapor escaping through said aperture, having been ignited from the mantle before the vapor was entirely shut off. This flame, which may be made of any size by changing the size of the aperture, serves to keep the generator heated continually, so that whenever the needle-valve is opened again the lamp is in condition to burn at its fullest capacity. When the valve is opened, the valve F is brought at once to the vertical position, the mantle receiving the full head of vapor ignited from the jet-flame just described. The stop member or arm T may be operated either by a spring or by gravity, it being normally in position to interrupt the movement of the needle-valve. When it is desired for any reason to. shut the lamp completely oif, the arm is thrown out of the way, so that the plate P can approach the valve closer and permit the point of the needle to seat.

As shown in Fig. 5, the chamber D and the pipe members J and L are connected integrally by the webs a and b, the heat from D being conducted through the metal webs to the entire generator members.

Other means than that shown may be employed for closing the top of the chamber D, and if the flap-valve is used other means for opening and closing it may be resorted to without departing from the spirit of my invention. Furthermore, changes may be made in the various other parts of the device as will suggest themselves to the experienced person.
