OIL-STOVE BURNER.

Specification of Letters Patent.

Patented Feb. 22, 1916.

Application filed September 17, 1915. Serial No. 51,201.

rangement of parts hereinafter described and definitely pointed out in the appended claims.

The object of my invention is to provide a means for holding the lower flange of the 'flamespreader of a round-wick burner up off of the end of the wick, to prevent smoking, and to facilitate lighting of the wick, in that class of wick-burners illustrated by the Perfection heating and cook stoves, heretofore patented by the assignor of the Standard Oil Company, an Indiana corporation.

In the drawings, Figure l is an elevation of a burner, partly in section, having my invention applied thereto, Fig. 2 is a sectional plan view of same, the section being taken on line -22 of Fig. 1, and Fig.8 is an inverted plan of the lower end of the air-tube.

The numeral 1 indicates the usual reservoir, in which the kerosene or other oil is placed, to be absorbed by the wick 2, which latter is located vithin the usual wick tube 3.

Mounted as usual within the said wick holder (or wick tube) 3 is the common threearmed spider a, beneath the three arms of which the hooks 5 of the air-tube 6 engage, so that the said tube and the entire flame spreader carrying both the upper and lower spreader-flanges will be detachably held within said wick-tube 8, during operation of the burner.

Heretofore, in that class of oil-stoves known on the market as the New Perfec tion, much trouble and inconvenience has been occasioned by the fact that the weight of said air-tube 6 and all of the spreader parts above it, caused the lower flamespreader flange 7 to rest too near the upper end of said wick 2. and in some cases to rest directly upon said wick; thereby interfering with the combustion, and producing much disagreeable smoke, soot and odor, be sides wast the fuel in such useless production of so and soot. The soot was-deposited upon the said lower spreader-flange 7 to such an extent that it interfered with the flame, and had to be removed by wiping or scraping. I avoid all such disagreeable action by inserting within said spreader air-tube, or by attaching to some part of the spreader, an improved device for holding said lower spreader-flange up a distance from the upper end of said wick. In the present instance, I have shown a coil spring 8 for such purpose. The upper end of said spring 8 rests beneath the upper spreaderflange 9, in the present case, while its lower end rests upon the said arms of the said spider a.

The operation is as follows: The said spring 8 being compressed by the act of inserting the spreader air-tube 6, within said wick-tube presses upward against the said upper spreader-flange 9, and lifts and holds up the. entire spreader until the said hooks 5 are held in contact with the under sides of the spider-arms, and until the lower spreadersflange 7 is supported at a distance above the end of said wick 2, and is held thereat during the entire operation of the burner, thereby permitting ample space between said end ofthe wick and said lower flange to produce perfect combustion, and prevent smoke, soot and disagreeable odors. The increased space between said lower flange 7 and the wick, also provides more room for the inserticn of the match, in lighting the burner. The flame-spreader and its air-tube 6 are secured in position and detached in the usual manner, by partially rotating the same, to cause the said hooks 5 to engage or disengage the arms of the said spider 4L.

What I claim is:

1. In a wick-fed burner for oil-stoves, the combination of a wick-tube, a wick, a flamespreader provided with upper and lower spreading-flanges, an air-tube at the lower end of said spreader, a series of laterallyextending hooks at the lower end. of said air-tube, a part fixed within said wick-tube fixed within said wick-tube, and having its 7 lower end resting thereon and its upper end in engagement with some suitable portion of the said flaniespreader, whereby the said spring will normally support the weight of the said flame-spreader, and will retain the said lower spreading flange a suitable distance above the plane of the wick, to prevent smoking.

2. In an oil-stove burner having the usual wiclvtube, a flame-spreader provided with upper and lower flamespreading flanges, an air-tube having at its lower end laterally projecting hooks, a spider having arms and fixed within said wick-tube, and a coilspring located within said air-tube, with. its lower end resting upon said spider and its upper end extending upward and engaging Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents, 7

the inner surface of the said upper spreading-fiange, whereby the entire flame-spreader will be held yieldingly in position with said lower spreadingfiange elevated a distance above the upper end of said wick-tube and the wick carried thereby; the said hooks normally engaging the undersides of said spider-arms, to prevent said spring from lifting the parts toohigh.

In testimony whereof, I have signed my name to this specification, in presence of two subscribing witnesses.

JOSEPH T. MILLS.
