E. P. RUSSELL non HIMSELF) AND PORTER TREMADT, (ASSIGNEE on E. P. RUSSELL,) OF MANLIUS, NEW YORK.

Letters Patent No. 7 0,27 2, dated October 29, 1867; reissue No. 3,195, Nobentber 17, 1868.

MODE 0! G- STREET-G-AS BURNERS.

Zl'hnSchQd-uh referred to in these Letters Patent and making pn t ofthe lame do hereby declare that the following is a full, clear,

and exact description thereof, reference being had to the accompanying drawings, forming a part of this specification.

Figure 1 is a vertical section through the main gasbumer and the supplemental or lighting-burner.

Figure 2 is a section through the gas-cock.

My invention consists in providing the inain gas burner with a small supplemental gas-burner, 'on a small pipe branching from the main pipe at short distance below the main burner, so that a small and constant jet of flame from the small burnerwill serve to light the large burner when its cock is turned.

This device is to be used principally in connection with an automatic device for lighting street-lamps. There are various devices and modifications of my invention, but I prefer that shown in the drawing.

The gas flows continually up through the lighting: burner A, which is made cup-form, with a very small orifice, and is there lighted and kept constantly burning in a small jet.

The cock C, of the main burner B, is operated by suitable machinery, or by hand, so as to be turned off or on at any desired time. As soon-as the cock is turned on, the gas escapes at the main burner, and is instantly lighted by the small jet issuing from the lighting-burner.

The value of the very small quantity of gas needed to maintain a sufiioiently constant lighting-j et is almost inappreciable, scarcely more (if as much) than that of the matches ordinarily used.

. The supplemental pipe may, however, be attached either above or at the cock 0, so as to be controlled by it, or it may have a separate cock of its own.

1 I do not claim an iuterrnitting gas-jet for lighting the main burner, as claimed by Locke and U-lriok, patented the 16th da'yofApril, 1867.; but

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

A small supplemental burner, A, to be kept burning constantly, and the pipe leading thereto, when operating in connection with a main burner, substantially as and for the purposes set forth.

E. P. RUSSELL.
