Specification of Letters Patent.

Patented Dec. 19, 1905.

Application filed November 29, 1904. Serial No. 234,688.

To all zul/1,0m, it may concern:

Be it known that we, ELLswoRTH Ross and JOEL ARTHUR BoYLEs, citizens of the United States, and residents of Lynch, in the county of Boyd and State of Nebraska, have invented a new and Improved Lamp-Burner, of which the following is a full, clear, and exact description.

The purpose of the invention is to provide a lamp-burner with a combined air and gas relief tube having such relation to the outlet end of the wick-tube that all of the gas and air will be extracted from the container as fast as generated therein and be fed to the iiame and consumed without smothering the ame, thereby eliminating every possibility of the lamp exploding, though either gasolene or a poor quality of kerosene be used.

A further purpose of the invention is to provide a combined air and extracting and relief tube capable of convenient application to any air-tight burner, the said tube being open for communication with the bowl or container to which the burner is appliedV and having its upper or outer end closed and its upper portion looped or coiled around the wick-tube at its upper end, the said loop-section of the extracting or relief tube being provided with perforations, so that when the wick is lighted a suction is created at the loop-section of the relief or extracting tube, which causes the air and gas to be continuously drawn up from the container while the wick remains lighted and to mingle with the flame at its base, producing a steady regular illumination even in the absence of a chimney.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claim.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of the burner, the cap being open. Fig. 2 is a plan view of the burner with the cap in open position. Fig. 3 is a bottom plan view of the burner, and Fig. 4 is a vertical central section taken practically on the line 4 4 of Fig. 3.

The burner is of that type which is attached to a container in an air-tight manner and comprises the usual body A, having a closed bottom 1() and a wick-tube A', which extends through the said closed bottom and in which the wick 11 is operated by means of the usual raising and lowering mechanism A2, and A3 represents the cap for the burner.

The extracting or relief tube B consists of a body-section 12, which extends from a point near the upper end of the wick-tube A atA one side and down and out through the closed bottom 10 of the body A of the burner, as is best shown in Fig. 4. The outer end 13 of the said extracting or relief tube B is closed in any approved manner; but the lower or inner end of the said tube is open, so as to be in direct communication with the interior of the bowl or container to which the burner is applied. The upper portion of the said tube B is bent upon itself to form a loop 14, Which loop is fitted to and extends around the exterior of the wick-tube A as near the top as practicable, and in the upper face of the said loop 14 a series of apertures 15 is produced.

This attachment for burners is exceedingly simple and may be readily applied to any burner`having an air-tight connection with an oil-container, and in operation when the wick is lightedthe heat creates a suction at the apertured portion of the loop 14 and causes the gases and air in the container to be constantly drawn upward or extracted from the container and delivered to the flame at its base, and the gases and air thus extracted and thus mingled with the iame cause the flame to burn steadily and give an even illumination, it being unnecessary under some conditions to have a Vchimney on the burner, as even in the absence of a chimney the light will remain practically as stead and as pure as when a chimney is employe This constant extraction of gases and'air from the container and their delivery to the flame are an absolute safeguard against explosion, even though gasolene be burned or a very inferior quality of kerosene.

Having thus described our invention, We claim as new, and desire to secure by Letters Patent- A lamp-burner provided with a relief-tube, comprising4 a body-section open at its lower end and having its upper end closed and formed into a loop fitting snugly around the IOO Wek-tube near the top thereof7 the loop havnames to this speeeaton in the presence of ing its upper face apertured, the body-see two subscribing Witnesses.
