GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 754,075, dated March 8, 1904..v

Application filed July 6, 1903. Serial No. 164,298. (No model.)

To all whom it may con/cern,.-

Beit known that I, WILLIAM KoHN, a subject of the Emperor of Austria-Hungary, residing at Brooklyn, in the county lof Kings and State of New York, have invented certain new and useful Improvements in Gas-Burners, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to gas-burners; and the object thereof is to provide an ordinary illuminating-gas-burner fixture with an electrical attachment which will automatically operate to reignite the gas if the latter be accidentally blown out or extinguished in any other way without being turned oif; and with this and other objects in view the invention consistsl in an electrical attachment for gasburners of the class and for the purpose specied constructed as hereinafter described and claimed. I

This invention is an improvement on that described` and claimed in another application for Letters Patent of the United States, led by me April 8, 1903, Serial No. 150,906, and is fully disclosed in the following specification, of which the accompanying drawings form a part, in which lthe separate parts of my improvement are designated by suitable reference characters in each of the views, and in which- Figure 1 is a sectional side elevation of an ordinary gas fixture and burner provided with my improvement; Fig. 2, a bottom plan view of the valve portion of the xture; Fig. 3, a section on the line 3 3 of Fig. 1, and Fig. 4 a view similar to Fig. 1 and showing part of the construction on an enlarged scale.

In the drawings forming part of this speciication I have shown an ordinary gas-fixture which may be connected, with a wall, wallbracket, chandelier, or other similar device, and said fixture comprises a pipe a, having the usual valve c2, and in the form of construction shown said pipe is provided with an elbow member co3, with which is'connected a burner-tube at, provided with the usual burner-tip Connected with the upper end of the burnertube at is a casing c, provided with aV short shaft c2, with which is connected one end of a helical thermostat-spring c3, the other end of which is secured to the casing c at c4. Within the casing c are also placed two electrical contact devices Z and e, both of which are preferably secured to the burner-tube c* and insulated therefrom,as shown at d2 and e2, and connected with the shaft c2 and insulated therefrom is a rotatable contact device f, which is adapted to connect with both of the contact devices d and e.

Connected with the pipe a near the casing g of the valve a2 is a band g2, and this band is provided at one side with a horizontally-arranged segmental. member g3, and the end g4 of the valve c2 is provided with a spring-arm g5, the free end of which is adapted to bear on the segmental member g3 of the band g2, and when the valve a2 is in position to cut oif the flow of gas through the pipe a the springarm g5 is insulated from the member g3, as shown at g, said member g3 being provided with insulating material at Q6 for this purpose.

I also provide a battery z, or other generator or source of electricity, and a wire h2 is connected with this battery and with the pipe a or valve-casing g, or this connection may be made with the valve or with the springarm g5, and another wire is connected with the battery it and passed into the casing @and connected with the contact device e. Another wire j' is connected with. the contact device d, and in the form of construction shown is passed into the burner-tube and through the burner-tip band connected with a platinum coil v, arranged transversely of the top Iof the burner-tip, and connected with the other end of said coil is another wire m, which extends downwardly through the burner tip and through the burner-tube and the pipe c and the elbow as and is passed outwardly through the pipe a adjacent to the band g2, as shown at m2, and is connected with said band g2 at m3.

A coil n, of copper or other suitable metal, is wound on the burner-tip 5, and one end thereof is formed into an arm n2, which is passed into the casing c and bears on the thermostat-coil c3. When the parts are in the position shown in Figs. 1 and 2, the circuit is not complete, said circuit being broken at g; but if the valve be turned so as to permit the gas to flow through the fixture the arm g5 will bear on the segmental member g3 and the circuit will be complete and the platinum coil L will be heated and will ignite the gas flowing through the burner-tip. At this time the thermostat-spring c3 is heated and throwsthe contact device f' into the position shown in dotted lines in Fig. 4 and the circuit is broken and remains broken as long as the burner is in operation, and during this time the battery z, is at rest. Ii' at any time while the parts are in this position the gas should be blown out or otherwise accidentally extinguished without cutting off-the flow, the thermostat c3 will immediately cool and the rotary contact device f will be turned thereby into the Yposition shown in full lines in Figs; l and 4, and the circuit will again be completed and the gas will be again ignited and the burning of the gas will again heat the thermostat and the contact device fwill again be turned into the position shown in dotted lines in Fig. t and the circuit will be again broken and the battery it will be at rest.

It will thus be seen that when the gas is not flowing through the `fixture the circuit is broken by the arm g5 and the battery is at rest, and when the gas is burning the circuit is broken by the rotary contactvdevicej1 and the battery is again at rest, and if at any time the gas is blown out or otherwise accidentally extinguished. without being turned orf Athe thermostat c3 will operate the contact device f to again close the circuit and relight the gas.

It will thus beseen that under usual conditions the `battery it is not in operation when the gas is burning and is also not in operation when the gas is turned off by the key, and by reason of this fact an ordinary dry battery may be used for a great length of time; but any suitable source of electrical supply may be provided.

rIhis device is simple in construction and operation and may be applied to illuminatinggas burners wherever desired, and changes in and modifications of the construction herein described may be made without departing from the spirit of my invention or sacriiicingits advantages.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a device of the class described, a gaslixture provided with a valve, a burner-tube, and a burneri-tip connected with said tube; a contact device connected with the fixture adjacent to the valve and provided with a segmental member, a spring-arm connected with the valve and operating in connection with said member, means for insulating said arm from said member when the gas is turned oif, a casing connected with the burner-tube, two insulated contact devices secured in said casing, a platinum coil supported across the burner-tip and one end of which is in electrical connection with one of said contact devices, and the other end of which is in electrical connection with the contact device secured to the fixture, a battery in electrical connection with the iiXture and with the other contact device within said casing, arotary contact device in said casing and adapted to complete the circuit betweenisaid stationary contact devices, a thermostat for operating the rotary contact device and` means connected with the burner-tip for heating the thermostat, substantially as shown and described.

2. In a device of the class described provided with a burner-tube and burner-tip, a platinum coil supported over the burner-tip, a casing secured to the burner-tube and provided with two stationary insulated contact devices, a rotary contact device mounted between the stationary contact devices, a thermostat for operating the rotary contact device, means whereby the heat of the burner will operate the thermostat, a 4wire connected with one end of the platinum coil and with one of said stationary contact devices, another wire connected with the other end of said platinum coil, a battery in an open circuit formed by said wires .and means whereby the turning on of the gas will complete said circuit, substantially as shown and described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of the subscribing witnesses, this 3d day of July, 1903.

WILLIAM KoHN.
