GAS-BURNER ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 778,252, dated December 2'7, 1904. I

Application filed January 19, 1904. Serial No. 189,689.

To all whom it may concern:

Be it known that I, WILLIAM KoHN. a subject of the Emperor of Austria-Hungary, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Gas-Burner Attachments, 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. I

V This invention relates to gas-burners; and the object thereof is to provide an ordinary gas-burner fixture with electrical attachments whichare automatically operated to reignite the gas if the latter be accidentally blown out or extinguished in any other way without being fully turned ofl and with this and other objects in View the invention consists in an attachment for gas-burners for the purpose specified'constructed as hereinafter described The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which the separate parts of my invention are designated by suitable reference characters in each of the views, and in which' Figure 1 is a side view of a gas-burner fixture provided withmy improvement; Fig. 2, a diagrammatic view showing the electric circuits and showing a circuit-closer at right angles to the position shown in Fig. 1 and also showing other parts of the construction; Fig. 3, a

' side view of a'detail of the construction on an enlarged scale. Y 1

In the drawings forming part of this'specification, 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 theusualvalve-casing and valve a and in the form of construction shown said pipe is provided with an elbow member (0 with which is connected anordinary burner-tube a, provided with the usual tip 6.

Connected with the pipe (0, near the casing of the valve 06 is a band 0, provided at one side with a horizontally-arranged segmental member 0 and the handle part a of the valve a? is provided with a spring-arm 0 the free end of which is adapted to bear on the segmental memberc of the band 0, and when the valve of is in position to cut oil the flow of gas through the pipe (0 the spring-arm 0 is insulated from the member 0 as shown at 0 said member being provided with insulating material at 0*.

Mounted on or connected with the upper end of the burner-tube a in any desired manner is a disk or support d, with one side of which is secured an upwardly-directed finger d with'which is connected a vertically-arranged thermostat d", which projects a predetermined distance above the burner-tip Z) and which is bent to form lateral convolutions, as clearly shown in Fig. 1, and which is adapted to expand and contract under the influence of heat and cold and for which purpose the said member cl is preferably made of differentmetals, such as are usually employed for such purposes. On the side of the support d with which the arm (Z is connected said support is provided with downwardly and outwardly directed arms a, with which is connected an insulated block 6 to which is secured a contact-piece c and pivoted to the base portion of the arms a is an upwardlydirected arm f, having adownwardly-directed finger f adapted to make contact with the contact device 0 and said arm f or the part f thereof, is provided with a supplemental arm f which projects transversely of the burner-tube in a direction opposite to that of the arms 0 and which is weighted at its end, as shown at f The upwardly-directed arm f is composed of two parts, f and f, which are insulated from each other by an intermediate part f and the finger f is formed on one of the parts, f, and the other part, f, is insulated therefrom. The part f of the arm f is provided at its upper end with an outwardly-curved and transversely-directed member g and the part f is provided with an outwardly-curved member,-having a curved finger-piece 9 which projects transversely of the upper end of said arm and over the member W, and the parts 9 and g are connected by a transversely-arranged coil of platinum. I

The band 0 is insulated from the pipe at and is also provided with a battery it, which may be placed at any desired point and which is connected with the band 0 by a wire 7& and with the contact device a by a wire a It will be understood that the upper end of the thermostat (Z operates, in connection with the finger g at the upper end of the arm f, to move said arm f, as hereinafter described, and the operation of this form of construction will be readily understood from the foregoing description when taken in connection with the accompanying drawings. Suppose the parts to be in the position shown in Fig. 1, in which position the spring-arm c rests on the insulator at 0*, with which the segmental member 0 is provided. If now the gas be turned on, the arm 0 will rest on the segmental member 0 and the circuit will be completed from the battery through the wire it, through the contact device 0 through the part f of the arm f, through the platinum coil and down through the other part f of said arm and through the parts (Z, a", a and the valve a the spring-arm (t the segmental member 0 the band 0, and the wire b to the battery. This current will heat the coil g and ignite the gas, and itat any time the gas be blown out or accidentally extinguished the thermostat (Z will contract and the arm f will assume the position shown in Fig. 1, and the circuit will again be completed and the gas reignited by the coil 9, and as the gas continues to burn the thermostat 6Z3 will expand and'the finger f will be separated by the arm f from the contact-piece e and the circuit will again be broken, and it will thus be seen that the battery is only in position when it is necessary to light or relight the gas.

In the construction shown in Fig. 2 the parts are exactly the same as hereinbefore described, except that the battery it is connected with the pipe to by a wire v and with the supplemental arm f by another wire, 2' and the band 0 is connected with the contact-piece 0 by a wire With this form of construction the current when the gas is turned on, as shown in Fig. 2, passes through the battery, through the wire 3, the part f 5 of the arm f, through the platinum coil 9, the part f of the arm f, and through the finger f the contact device 6, the wire t the band 0, the segmental member 0 the spring-arm 0 and the valve a to the pipe (4, and through said pipe to the battery through the wire 2'. In this operation the current heats the coil and the gas is ignited thereby, and when the thermostat d becomes heated the arm f operates, as hereinbefore described, to break the circuit, and if at any time the gas is accidentally blown out or accidentally extinguished without turning ofi the fiow thereof the thermostat (X will contract, and the arm f will operate to complete the circuit, and the coil will be again heated and the gas reignited.

This device is simple in construction and operation and perfectly adapted to accomplish the results for which it is intended, and changes in and modifications of the construction herein described may be made without departing from the spirit of my invention or sacrificing its advantages.

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