EDWIN C. DIGKINSON, OF TALCOTT, WEST VIRGINIA.

GAS-BURNER.

Specicaton of Letters Patent.

Application led May 3, 1911.

Patented Apr. 30, 1912.

Serial No. 624,687.

To all whom t may concern Be it known that I, EDWIN C. DICKINSON, a citizen of the United States, residing at Talcott, in the county of Summers and State of West Virginia, have invented new and useful Improvements in Gras-Burners, of which the following is a specification.

This invention relates to certain novel and useful improvements in gas burners.

In carrying out my invention, it is my purpose to provide an improved gas burner which may be used in conjunction with gas fixtures for either artificial or natural gas.

A further object of the invention is to provide a valve, suitably located in the gas supply pipe leading to the burner, said valve having connections with a thermostatic rod arranged within the burner, whereby said valve will open and close responsive to the expansion and contraction of the rod.

A further object of my invention is to providea simple, reliable and eiiicient form of device for thermostatically controlling the opening and closing of the valve within the supply pipe, whereby said valve will be automatically closed when the light has been extinguished, thereby obviating the liability of gas accidentally escaping from theburner.

With the above-recited objects and others of a similar nature in view, the invention consists in the construction, combination and arrangement of parts set forth in and falling within the scope of the appended claims.

In the accompanying drawings :-'-Figure 1 is a view in side elevation of a gas burner embodying my invention, the gas mantle and support therefor being shown in dotted lines. Fig. 2 is a top plan view of the burner. Fig. 3 is a vertical sectional view. Fig. 4 is a cross sectional view, taken on the line 4-4 of Fig. 3. Fig. 5 is a similar view, taken on the line 5-5 of Fig. 3. Fig. 6 is a cross sectional view taken on the line 6-6 of Fig. 1. j

Referring now to the accompanying drawings in detail, the numeral l indicates a `supply pipe adapted to be threaded at its end 2 into a gas fixture of any suitable character, the opposite end of said -pipe being connected to the elbow 8, said elbow also having threaded therein the vertical tube 4, forming part of the gasV burner proper. This vertical tube is provided intermediate its length with a horizontal partition 5 having a perforation or opening 6 for the passage of gas, said opening being controlled by a pivoted plate or slide 7 having graduated perforations 8 arranged therein and designed to be brought into alinement with the opening in the partition to regulate the amount of gas admitted to the mixing chamber. This tube is also formed above the partition with air inlet slots 9, designed to register with similar slots 10 formed in the upper tubing 11, which is sleeved or telescoped over the end of the tube 4.

The numeral 12 indicates a rotary collar having the under side 13, open for the admission of air to the mixing chamber, which chamber is formed by the tubes above the partitions 5 and is indicated by the letter m. This rotary collar is formed with vertical stops 14 between which the end of the pivoted plate or slide projects, whereby said collar when rotated will move said slide to bring the desired opening thereof into alinement with the opening in the diaphragm. As this method of regulating the amount of vair and gas admitted to the mixing chamber is old and well-known in the art, I lay no claim to the same. The upper or telescoping tube 11 is formed at-its lower end with a circumferential flange 15, which is spaced apart from a similar flange 16 carried by the tube 4, the screws 17 connecting the tubes at the flanges, each of screws being surrounded by a coiled spring 18, designed to tension the upper tube, the latter having a certain amount of movement relative to the tube 4, the upward movement of the telescoping tube being limited by the head of the screws 17.

The thermostatic control regulating device for the burner is best shown in Fig. 3, wherein the numeral 19 designates a block located within the supply pipe and having a gas port or passage therein, which is inj dicated at 20, said port being controlled by the beveled valve 21, carried by the rod 22 which latter is fulcrumed or pivoted at 23 to the block 24, the end of said rod extending into vthe elbow 3 and is pivotally `connected at 25 to the thermostat rod 26, which latter extends vertically upward through the mixing chamber of the burner, the rod being threaded at 27 in the ring spider 28 at the top of the telescoping tube 11, the upper end of said thermostat projecting into the mantle attachment as shown at 29 in Fig. 1. The mantle attachment is designated by the letter X, but as this mantle and its support isV of a well-known type, and forms no part of the present invention it need not be described in detail.

From the above description taken in connection with the drawings the construction and operation of my improved burner will be readily apparent. The usual gas cock is turned to permit the llow of gas through the channeled or bored block, and into the supply pipe, the telescoping sleeve being pressed downward momentarily to permit this. The gas is then lighted, and as the thermostatic rod becomes heated so that it expands, and in such expansion presses down against the lever rod 22 at the end 25 thereby elevating the valve 2l from the month of the passage 20, thus permitting the gas to flow through the burner to the mixing chamber and point of ignition. So long as the gas is lighted, the rod will be heated and the valve elevated from its seat in the block. 2l/Then the gas is turned off the rod cools and contracts, and the valve drops back into closing position.

It will be noted that I have provided a safe, eliicient and simple means for insuring that no gas will escape from the burner when the light is extinguished, and furthermore my invention is applicable to any type of burner, either for natural or artificial gas.

While I have herein shown and described one particular embodiment of my invention, by way of illustration, I wish it to be understood that I do not confine myself to all the precise details of construction herein set forth, as modification and variation may be made without departing from the spirit of the invention or exceeding the scope of the appended claims.

lVhat I claim is l. The combination with a gas supply pipe, of a burner connected thereto and including a tube, and a sleeve telescoping over said tube, a mixing chamber for air and gas formed by the sleeve and tube, a resilient connection between the sleeve and tube, a rod pivoted in the supply pipe, a valve carried at the end of said rod and controlling the gas channel to the supply pipe, a thermostatic rod extending through the burner and pivoted at its lower end to the first-men tioned rod, the construction and arrangement being such that the valve is elevated to permit gas to enter the supply pipe when the rod is expanded by the heat from the burner, said valve being closed upon the contraction of the rod.

2. The combination with a supply pipe, a channeled block located in the supply pipe, a rod pivoted in the supply pipe, a valve formed integral with the rod at one end thereof and closing the channel in the block, a gas burner connected to said supply pipe and comprising a stationary tube, a sleeve sliding on said tube, a resilient connection between the sleeve and tube, a diaphragm in the tube having an opening for the flow of gas therethrough, said tube and sleeve having alining openings for the admission of air, and resilient connections between the sleeve and tube, a metallic rod extending through the tubes and connected intermedi ate its length to the sliding sleeve near the top of the latter and connected at its lower end to the valve carrying rod, the construction and arrangement being such that said valve is open when the rod is expanded by the heat of the burner, and closed when said rod contracts.

In testimony whereof I affix my signature in presence of two witnesses.

EDIVIN C. DICKINSON.
