EAR-L B. STONER, OF ASTORIA, OREGON.

SPECIFICATION forming part of Letters Patent No. 741,736, dated October 20, 1903.

Application filed September 9, 1902. Serial No. 122,738. (No model.)

To all whom it may concern:

Be it known that I, EARL B. STONER, a citizen of the United States, and a resident of Astoria, Glatsop county, State of Oregon,have invented a new and useful Improvement in Gas-Jet-Holder Attachments for Lamps of L- comotive-Headlights, of which the following I is a specification, reference being had to the accompanying drawings as a part thereof.

.The object of my invention is to provide an, attachment for the ordinary oil-burning lamp of so-called locomotive-headlights'for the purpose of converting the same into an acetylene-burner, at the same time leaving the oil-lamp in such condition that in case of an emergency my attachment may be readily removed, the oil-burner put back in place, and the lamp used as before.

I attain my object by the device illustrated in the accompanying drawings, in which Figure 1 is an elevation of the headlight on a locomotive, parts being broken away to show my attachment in place. Fig. 2 is an elevation of the usual oil-lamp body of a headlight, partly in section and my attachment being operatively applied. Fig. 3 is an elevation of a like lamp provided with my attachment and illustrates the use of a clamp as an additional means for securingm'y attachment in place. Fig. 4 is a partial elevation like Fig. 2, showing a modification in been removed.

My attachment consists of a jet or burner e, which is vertically adjustable in the apertured cover or plate t', so as to bring the flame within the focal center of the reflector. From the base of the burner e projects downward a stem Z, inserted in the socket m in which ordinarily is inserted thestem or pin of the deflector-plate. The upper part of the burner e has a cavity, and it is adaptedto receive the gas-tip f and the discharge end of functionates to vertically adjust the burner e, as mentioned. To this end such burner is provided with an exterior thread, and the aperture of the plate 41 is correspondingly threaded. Thus by turning the plate din eitherdirection the burner is raised or lowered. A clamp j may be used for steadying the burner and holding the same against being turned laterally by vibratory motion. A plan of such clamp is shown in Fig. 5. The part j is inserted on the gas-pipe g, and by the thumb-screw k the clamp is secured in place. The described means for adjusting the burner e are deemed preferable over others. Thethread of the adjusting parts may, however, be omitted, as illustrated by e and 71' in Fig. 4. The burner e merely slides up and down in the aperture of the plate i, and it is secured in place as adjusted by means of a clamp j. The receiving end of the gas-pipe is connected with the gas-gencrating apparatus by a rubber tube It.

Having fully described my invention, what I claim, and desire to secure by Letters Patout, is-- 1. The combination with the lamp-body and the wick-case therein of a plate constituting a closure for the wick-case, and having a cen- 2. Thecombination'with thelamp-bodyand the wick-case therein of a plate constituting aclosure for the wick-case, and having a central aperture, a burner vertically adjustable in the aperture of said plate, a gas-pipe entering the burner, and a clamp j for holding the burner in adjusted position, substantially as described.

3. The combination with thelamp-body,the wick-case and the socket, m, therein of a plate 1', constituting a closure for the wickcase and having a central, threaded aperture, a burner 6, provided with an exterior thread and vertically adjustable in said aperture of the plate 2', a dependent stem or pin, Z, on and means for securing the burner in ad- 10 the base of the burner, which stem is inserted justed position, substantially as described. in the socket m, and a gas-pipe entering the In testimony whereof I have hereunto afburner, substantially as described. fixed my signature, in the presence of two 5 4.
