GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 744,290, dated November 17, 1903.

(No model.)

To all whom, it may concern.-

Be it known that I, WILLIAM B. OARBICK, a citizen of the United States, residing at Chicago, in the county of Cook and State of'Illinois, have invented certain new and useful Improvements in Gas-Burners and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relatesparticularly to means for simultaneously lighting a cluster of gasburners, and includes a supplementary or lighting burner, which projects flames laterally in various directions over the main burners, and also a pilot-light for lighting such supplementary burner at all times.

The invention is an improvement on the invention patented by me March 3, 1903, No. 721,997.

In the accompanying drawings, Figure 1 is an elevation of the burner. Fig. 2is an elevation at right angles to Fig. 1 and partly in section.

Referring specifically to the drawings, 6 indicates the main depending supply pipe, which extends downwardly through a tube 8. This tube is preferably enameled or coated with some reflecting material, such as porcelain, and is supported on the pipe by a gallery 9. At 10 areindicated the main burners, forming a cluster around the said reflectingtube 8 and supplied through the main cock 11. Above said cook a branch pipe 12 is united .to the main supply-pipe, and this branch pipe supplies gas to a secondary or lighting tube 13 and a pilot tube or burner for the latter, (indicated at 14.) These tubes pass within the reflecting-tube 8 through a hole in the gallery. The pilot-light at 14: at the end of the tube 14 is within the tube 8, so that the latter acts as a protector for the pilot-light. The tube 13, however, projects above the top of the tube 8 and is provided with holes or nipples 13*, which project laterally in direction and number, according to the number of main burners in the cluster.

The branch pipe supplyinggas to the supplemental burner and the pilot-light is controlled by a cock 15, which has the usual by-pass supplying the pilot-light at all times. When the cock is open, it allows gas to pass into the tube 13, and thusto the supplemental burner 13 but the cock is normally closed by a spring 16. Pull-chains to open and close the main cock are indicated at 17 and 18, respectively. The former has a branch chain 17 to the cook 15 of the by-pass and between the junction of the chains and the main cock has a spring 19.

The operation of the device is as follows:

' Gas is constantly supplied through the main and branch pipes to the pilot-light, and when it is desired to light the cluster the chain 17 is pulled. This first turns on the gas to the burners of the cluster. Further pull causes the spring 19 to yield and the branch chain pulls open the cock of the branch pipe, as indicated in dotted lines in Fig. 2. This turns on the gas to the supplemental burners 13*, which project flames laterally over the tops of the main burners 10, thereby igniting the same. When the pull-chain 17 is released, the spring 16 closes the cook 15 in the branch pipe and puts out the flames at 13?, allowing, however, the pilot-light to remain burning through the by-pass.

It will be seen that by this device it is unnecessary to have a pilot or lighter for each burner; but the whole cluster may be lighted simultaneously by means of one pilot-light. A saving of fittings is thus efiected, as well as a saving of gas.

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination with a cluster of burners, of an independent burner between the same, a pilot-light for the independent burner, a valve-controlling gas-supply to all of said cluster, and a valve-controlling gas-supply to the independent burner and pilot-light.

2. The combination with a main supplypipe and a cluster of burners, and a valve in the pipe controlling the gas-supply to the burners, of a branch pipe, an independent burner and its pilot-light supplied thereby, said independent burner having laterally-directed nipples the flames from which are in the pipes, and a chain connected to said 10 l valves to operate the same.

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

WILLIAM B. CA RRICK.
