BURNER.

SPECIFICATION forming part of Letters Patent No. 743,148, dated November 3,1903.

Application filed May 2, 1903. Serial No. 155,295. (No model.)

ing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Burners, of which the following is a specification,

reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in lamp-burners, and relates more particularly to that class of burners in which a wick is used and wherein a burner is suitably connected to the top of the lamp in which the oil is contained.

The object of the invention is to provide a burner whereby a light may be quickly and readily'oxtinguished when desired.

A further object of this invention is to provide a burner which is absolutely non-explosive, thereby overcoming the dangers which have been coincident with the use of a lamp of this type.

In describing the invention in detail reference is had to the accompanying drawings, forminga part of this specificatiomand wherein like numerals of reference indicate like parts throughout both views, in which- Figure 1 is a side elevation of a lamp equipped with my burner, the same being partly in section. Fig. 2 is an elevation looking toward the right of Fig. 1, the same being in section.

The reference-numeral 1 indicates a screwthreaded portion of the burner, which is connected to the metal part 2, fused onto the lamp-bowl 3. Secured to the upper edge of the part 1 is a shell 4, on the upper end of which the brackets 5 5 are secured, these brackets extending outwardly and support ing at a point intermediate of their length the lamp-strainer 6, upon which the cap 7 is pivoted. Extending through part 1 in either direction is a wick-casing 8, the lower end of which extends nearly to the bottom of the lamp-bowl and is provided with apertures 9 for the purpose of admitting the oil to the wick contained therein, and the upper portion of this wick-casing extends nearly to the top of the cap 7 and has provided and secured to its outer edges the slotted members 9 9. Pivotally mounted on the wick-casing inside the casing 4 is a lever 10 for actuating the extinguisher of the lamp, said lever preferablyextending outwardly and slightly below the wheel 11, by which the vertical position of the wick is controlled. The said lever 10 has a short arm 12, the end of which is provided with a slightly-enlarged portion 14, which engages in the member 15, which is suitably formed to have the enlarged portion 14 operate therein. Attached to the upper side of this member 15 is a vertical rod 16, which passes through the bracket 17, formed on the side of the wick-casing S, and a coilspring 18 encircles said rod 16 between member 15 and bracket 17 for the purpose of keeping the rod 16 in its lowered position. The upper end of this rod 16 has a loop formed thereon which engages the lower edge of the extinguishing-cap 19, said cap having projections 20 20 on either side which extend through the slots in the members 9 9.

The operation of this part of the burner is as follows: When it is desired to extinguish the. light, the lever 10 is depressed, thereby elevating the extension 12 thereof, the enlarged portion 14 of which will elevate member 15, carrying with it the rod 16, thereby compressing spring 18, and the extinguishingcap may be moved upward until such time as extensions 20 reach the ends of the slots in the members 9, when the cap 19 will be forced over the top of the wick-casing 8,thereby snuffing the wick and efiectually extinguishing the light. The screw-threaded part 1 is provided with a plurality of apertures 21, which permit the gas which may be formed within the bowl of the lamp to pass upwardly and into the casing 4, and a plurality of apertures 22, provided in the lower portion of said casing, to permit the same to escape to the outside air, thereby preventing the accumulation of gas within the bowl of the lamp.

Another feature of this invention consists in having wick-casing 8 of such length between its connection with the bowl of the lamp and the igniting-point of the wick that at its point of entrance into the lamp-bowl the same will be cool, thereby also doing away with the danger which now results from the parts which are in contact with the oil becoming heated.

It will be noted that various changes may be made in the details of construction without departing from the general spirit of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, 18-

1. In a lamp-burner, the combination of a wick-casing, to the central portion of which a member adapted to connect the burner with the bowl of the lamp is secured, and a portion of said casing extending within said lamp, the lower end of the same being provided with oil-inlet apertures, the upper end of which wickcasing being provided on its edges with slotted guides in which projections formed on the snuffer plate extend, said plate having a rod pivotally connected to its lower end, the lower end of said rod being pivotally connected with an actuating-lever whereby said plate may be thrown into operative position, and a spring normally holding said plate in its inoperative position, substantially as described.

- 2. In a lamp-burner, the combination of a wick-casing, a member for connecting the same with the body of the lamp having apertures therein for the escape of gas from the bowl of the lamp, the lower end of said casing extending Within the oil and being provided with a plurality of apertures, a snufier-plate located adjacent to the upper end of said casing and having a limited sliding connection therewith, a rod pivotally connected to said plate, means for elevating said rod whereby said plate may be brought into operative position, a spring normally holding said plate in its inoperative position, whereby the gas may escape from the bowl of said lamp, substantially as described.

3. In combination with a lamp of the character described, a wick-casing having a lower portion adapted to extend within the oil and provided with a plurality of apertures, slotted members carried by the upper portion of said wick-casing, a snuffer-plate slidably engaging with said slotted members and means for actuating said snu l ter-plate, substantially as described.

4. In a lamp of the character described the combination with the bod y of the wick-casing, means for connecting said casing with the body, said casing being provided with a lower extended portion projecting through said connecting means within the oil of the body and being provided with oil-inlet apertures, slotted members secured to the upper portion of said wick-casing, a snuifer-plate slidably secured to said members, means for actuating said snufEer-plate, and means for normally holding the plate in inoperative position.

5. In a lamp of the character described a wick-casing, means for connecting the same with said lamp having apertures therein for the escape of gas from the lamp-bowl, said casing having an outwardly-extended portion provided with a plurality of apertures adapted to admit oil to the wick, slotted members secured to the upper portion of said wick-casing, a snuifer-plate having slidable connections with the slots of said members and means for actuating said snufier-plate, substantially as described.

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

ANDREW J. COGI-IE.
