FREDERIC E. BALDWIN, OF NEW YORK, N. Y.

BURNER FOR OIL-LAMPS.

1 ,oeeaec.

Application filed November 17, 1911.

To all whom it may concern Be it known that I, Fnnnnnro E. BALDWIN, a citizen of the United States, and a resident of New York, county and State of New York, have invented a certain new and useful Improvement in Burners for Oil- Lamps, of which the following is a full, clear, and exact specification.

This invention relates to a class of burners adapted to be used in conjunction with lamps which burn oil especially for lighting purposes.

My invention has for its object primarily to provide a form of burner or device designed to be employed upon oil lamps whereby a proper combustion of the fuel products will be maintained when the wick of the lamp is ignited and which is adapted to prevent sutficientheat from being generated to volatilize the oil in the lamp-body, which ordinarily produces an excess of smoke and frequently a distribution of offensive odors from the liberation of free gas unless the wick of the lamp is lowered suiiiciently to greatly dim the light. This is accompllshed mainly by providing a deflector adapted to supply air to the lower part of the flame where the fuel products transmitted by the wick first undergo combustion and to provide a second deflector for supplying air to the flame above the first feed of air whereby all excess of gaseous products w1ll be consumed by the combustion for producing a light of unusual brilliaucy.

Another object of the invention is to provide a form of burner adapted to carry a chimney of large diameter; and to further provide means which will permit the lamp to remain lighted when in the currents of strong winds.

lVith these and other objects in View, the invention will be hereinafter more particu larly described with reference to the accompanying drawing, which forms a part of this specification, and will then be pointed out in the appended claims.

In the drawing, Figure l is an elevation, partly in section, of one form of lamp with my improved oil burner applied thereto. Fig. 2 is an elevation of a form of lamp suitable for out-door use, and showing the burner as used in conjunction therewith. Fig. 3 is a top plan of the burner taken on the line IIII of Fig. 1, and Fig. 4 is a top plan of the third air injector used in one form of my burner.

Specification of Letters Patent.

Serial No. 660,894.

The oil burner or device 10 may be used in con unction with the usual or any preferred formof lamp, as 11, having a tube 12 for carrying a wick 13 whereby light may be produced within a building or other structure, as shown in Fig. 1, or said burner may be employed upon a lantern, as indicated in Fig. 2, which is especially suitable for use in the open air.

Around the upper port-ion of the wick tube 12 is a deflector 14 for supplying air to the lower part of the wick when ignited. The deflector lat has an annular wall 15 which is tapered whereby its lower edge is spaced for some distance from the wick tube, and its upper edge is spaced only a slight distance from the free end of said tube. The lower edge of the annular Wall 15 is rigidly held to the wick tube by a number of spaced short strips 15 so as to provide a passage 16 for air to be admitted therethrough and supplied to the lower part of the flame where the fuel products transmitted by the wick first undergo combustion. For the purpose of supplying additional air to the flame of the wick above the first fuel feed so that all excess of gaseous products may be consumed by the combustion and for producing a light of unusual brilliancy, a second deflect-or 17 is provided. The second air deflector 17 has a curved annular member or oriflced plate 18. The curved orificed plate 18 encircles the annular member 15 of the first deflector, and its inner edge is spaced from said annular member 15 for providing an air passage 19. The deflector 17 has a vertical wall 18 through which are a number of spaced openings 18. A chamber is provided between the wall and the plate 18. This plate may be placed at any desired height with respect to the top of the annular member 15 of the first deflector, but is preferably positioned on a different relative plane thereto, in order to efliciently supply through the passage 19 air to the flame above the feed of air produced by the first deflector. By varying the position of the plate 18 and enlarging or lessening the size of the air passage 19 thereof various shapes of the flame of the lamp may be provided as occasion requires.

In conjunction with my oil burner, a chimney, as 20, may be employed so that its lower end will rest upon the annular member or orificed plate 18, and by using a plate of large size a chimney of unusual diameter may be used, though it is evident that chimneys of any suitable diameter may be em ployed by varying the size of said. plate.

When the lamp is used in the open air I prefer to employ a draft inducing hood, as 21, which may be of any well known or preferred form, and as a means to prevent the occurrence of back drafts which extinguish the light and to prevent the flame from smoking, I provide a third air deflector 22 which is positioned below the level of the sum when the wick is ignited. The third air deflector 22 has an annular member or ring 23 surrmnnling the chimney 20, and said ring is supported so that currents of air will be forced under any condition to enter the air chamber of the wall 18 of the second air injector 17.

In practice I prefer to employ a large chimney upon a lamp having my improved form of burner, as above described. The volume of heated air therein when the wick is ignited will induce an exceedingly strong draft at the burner through the medium of the first deflector l t, and the second deflector 1'7. Part of the air is fed to the lower part of the flame of the wick where combustion first takes place, and part of the air is supplied to the flame at a higher point than the first feed of the air, thus all parts of the flame will receive an ample supply of oxygen. Moreover, the great volume of air which will pass through the chimney will serve to keep it cool, prevent it from cracking, and permit it to be readily handled with safety when desired.

In the foregoing description I have embodied the preferred form of my invention, but I donot wish to be understood as limiting myself thereto, as I am aware that modifications may be made therein without departing from the principle or sacrificing any of the advantages of this invention, there fore I reserve to myself the right to make such changes as fairly fall within the scope thereof.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination, with a lamp-body, and a wick-tube carried thereby, of an annulus provided with air inlet-s and surrounding the wick-tube, an annular deflector carried by the said annulus, and a tapered deflector surrounding the Wicktube and having its narrower portion above the wick tube and projecting above the annular deflector through the central opening therein, said central opening being large enough to allow the passage of air around the tapered deflector.

2. The combination, with a lampbody, and a wick-tube carried thereby, of an annular perforated chimney-support carried by the lamp-body and surrounding the wicktube. an annular incurved deflector carried by the chii'nney-support and having a cen tral opening, a tapered deflector mounted on the wick-tube and having its narrower portion above the wick-tube and projecting above the central opening in the annular incurred deflector, and a chimney carried by said chimney-support and surrounding both deflectors.

The combination, with a lamp-body, and a wick-tube carried thereby, of an annular perforated chimney-support carried by the lamp-body and surrounding the wicktube, an annular incurved deflector carried by the chimney-support and having a cen tral opening, a tapered deflector mounted on the wick-tube and having its narrower portion above the wick-tube and projecting above the central opening in the annular iucurved deflector, a chimney carried by said chimney-support and surrounding both deflectors, and an exterior deflector surrounding the chimney-support and the lower end of the chimney and arranged to deflect the outer air to the openings in the chimneysupport.

i. The combination, with a lamp-body, and a wick-tube carried thereby, of an annular perforated chimney-support carried by the lamp-body and surrounding the wick tube, an annular incurved deflector carried by the chimney-support and having a central opening, a tapered deflector mounted on the wick-tube and having its narrower portion above the wick-tube and projecting above the central opening in the annular incurved deflector, a chimney carried by said chimney-support and surrounding both deflectors, and an exterior deflector arranged to deflect the outer air to the openings in the chimney-support.

This specification signed and witnessed this sixteenth day of November A. D. 1911.
