T0 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.

lI`his invention relates to gasolene-vapor lighting-systems and pertains to a lamp and generator therefor.

It relates more particularly to a new form of generator for producing a combustible vapor and to an automatic relief valve in connection therewith.

The main object herein is to provide for the generator of a vapor lamp, or for. the vapor generator, an automatic relief device for the escape of an excess pressure of vapor in such generator and especially at such times as the vapor outlet valve and the fluid supply valve are closed such as to retain said pressure within the generator. The result of this high pressure if not relieved, is to break the generator thus rendering it unit for further use and such other objects will appear herein with reference to this automatic feature as will make its value understood.

Another object is to provide a vapor lighting system in which a lamp that is used for lighting purposes also produces vapor for other lamps, that is to say, instead of providing merely a vapor-generating machine as in some of the older methods, which gives no light, my system includes an actual light producing lamp, that may be placed where desired, which produces vapor for the other lamps of the system. y

Another object of my invention is to produce a new structure for a generator.

Figure l is a vertical sect-ion of a lamp showing my invention. Fig. 2 is a longitudinal section of an automatic relief valve shown in Fig. l. Fig. 3 is a transverse seotion of a part of the same on line :c a' Fig. 2. Fig. 4 is a horizontal section of the relief valve shown in the first two gures. Fig. 5 is a horizontal section of a generator.

Since a system of conveying vapor to a series of lamps from a central source of vapor is well known, I shall not draw particular attention to the same herein but merely refer to such parts as may be necessary to explain the invention now under consideration.

A is a conduit for receiving vapor and for conveying it to a pipe B which supplies the lamps of the system. Suitably suspended from the lower extremity of the said pipe A by means of pipe sections C and D is a needle valve E whichl discharges vapor into said pipe A through said pipes C, D there being an air intake pipe section at F connected into the section D the purpose of which is well known. Secured into one side of the body of the valve'body E is a hori- Zontal tubular extension Gr of a generator which consists of a retort or pot H of a hollow cylindrical form having a central vertical tubular portion J opening entirelyl through it; said retort or pot I-I having an extension K opening into it opposite the portion G already described. The generator is filled with a non-combustible straining material H such for instance as asbestos as used in many lamps of this class there being two threaded plugs L in the top thereof through which the said filling can be inserted and through which said generator may be cleaned, from time to time as occasion may demand. Opening into one sideof the pipe A is a pipe M whose lower end is threaded and screwed into the top of the generator H to communicate with the central tubular portion J of the latter. Screwed in the bottom of the retort and also communicating with the member J is a tube N carrying at its lower end a burner N and the usual mantle O. The extension K of the generator receives a threaded extension of a valve K to receive a supply of gasolene which enters the latter through a feed pipe P. The fiuid enters a passage Q controlled by the needle It. A

S indicates a passage in the valve which comunicates with the passage Q, through which the fluid passes to the generator which upon entering the latter is heated by the mantle O or, when the lamp is first started, by means of asuitable torch as is well understood. The fluid upon becoming vaporized passes into the needle valve E and thence up into the pipe A to the pipe system to supply the lamps, part of said vaporbeing divided and forced into and down through the pipe N through the portion .I of the generator to the mantle. While generators are common for this purpose the one which I illustrate herein I regard as new in form and very efficient because of its peculiar construction and large heating surface. It entirely surrounds the conduit J through which the vapor passes, so that its heat will raise the temperature of the vapor to a very high degree 'before passing to the mantle. The generator being of a large size provides for a large heating surface so that any reasonable amount of fluid that` is supplied thereto is readily7 and quickly vaporized and it is practically impossible for any Huid to pass into or through the needle valve This form of generator I believe to be novel since it can be readily cleaned by an inexperienced person after removing the plug L. In co-nnection with this feature also the valve K can be unscrewed and removed from the extension K and a threaded plug C screwed into the needle valve E may be removed so that the generator can be reached from each side through the extensions K and G thereof for cleaning purposes.

In the present invention I have provided an automatic relief valve for permitting escape of heavy pressure from the generator and this will now be described. Vhile the lamp is in operation if the needle valve is closed when it is desired to interrupt the flow of vapor to the lamp circuit to extinguish the lights the great heat resident in the generator will vaporize the fluid as long as any of the latter is present therein and necessarily if the valve R is closed the pressure of the vapor will run very high often `reaching a pressure of several hundred said body K.

W which Vsurroundsthe steam V.

pounds. The extreme pressure having no way of escape results in very often breaking the generator and in View of this it has been my purpose to provide the automatic relief mentioned. The passage S in the valve body K is extended beyond the stem or needle R and terminates in a cavity T of A passage U connects said recess with the inlet passage Q above the needle substantially as shown and constitutes a by-pass. The extremity of the said passage S when it enters the said cavity T is recessed to receive what I shall term a check valve V which is held by means of a spring This spring bears at one end against the head of the said valve and at the other against a cap X covering the valve-body K. The valvestem lies within a socket V2 of said cap and its opposite end lies in the passage S and as shown in Fig. 3 is given a form that while centralizing the said check valve will permit the passage of the vapor therealong into the cavity T. The passage Q is enlarged around A the valve stem R as shownjin horizontal sece5- tion in Fig. 4 so that the vapor can pass around said stem and reach said check valve V. Now, although the valves E and R are closed the pressure from the generator will be relieved when sul'licient to move the valve V against its spring. The vapor then passes ,I may use other forms that will provide for the desired result. In extinguishing the lights of the system it is necessary rather than merely to stop the fluid supply to the generator, and let the vapor gradually burn out at the mantle of the lamps, to stop the low of vapor at once and entirely by closing the valve E. If the vapor is permitted to gradually lessen and the light to gradually go out the mixture of air with the vapor entering the pipe through a defective mantle causes an explosion which ruptures all the mantles of the system. The valve R cannot be left open since the generator would be filled with fluid which would cause trouble at the time the lamps are again lighted. The necessity for some form of relief is therefore evident.

My device as distinguished from the objects of others of its class provides for relieving pressure of vapor in the generator when the valves are closed so that the imprisoned vapor which, as before stated, in reaching a high pressure often cracks said generator, is allowed to return to the reservoir of the pipe system leading therefrom. Since the valve controlling the vapor passing toward the lamp system is closed for the purpose stated and the valve in control. of the fluid must be closed when extinguishing the lights the vapor must of necessity be allowed to escape.

I have provided the usual shade for the lamp which is indicated at 2. This is sup ported from a ring 3 hung in any good manner from the generator extensions K-G and mounted upon this ring 3 is a casing el to inclose the lamp and give it a prescntable appearance.

My system besides the structures mentioned is novel in that, as pointed out in the objects, a lamp for producing light is used as a generator for the series of lamps of the system, as distinguished from a system wherein the machine commonly employed for generating vapor provides no light at all and occupies considerable space. My combined distributing generator and lamp may be suspended in any room for lighting purposes out of the way and serves a double purpose.

I-Iaving pointed out the important features of the invention, I claim Y l. In a gasolene-vapor lighting apparatus the combination with a vapor-generator, of a gasolene conduit leading into the same and having a branch entering at its side, a valve smaller' in diameter than the diameter' of the conduit and extending across and through it adapted to close the opening of the branch, the said conduit extending beyond the valve, there being a separate pas-v sage connected with the extended end of the conduit and connected also with the branch of the latter and in permanent communication with the generator pastthe valve, and a check valve in said extended end.
