LANTERN-BURNER.
Specification of Letters Patent.
Patented Apr. 20, 1920.
Application filed February 1, 1919. Serial No. 274,517.
To all "whom it may concern:
Be it known that I, Gnonen H. RoLrns, a citizen of the United States of America, a resident of the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Lantern- Burners, of which the following is a full,
clear, and exact description, reference being had to the accompanyingdrawings, forming a part of this specification.
My invention relates to a burner for use in railway lanterns, in the handling of which lanterns the flame from the burner is liable to become extinguished and burn unevenly, due to suddenness and variety of motions given to the lantern, more particu larly in signaling actions. The present invention is in the nature of an improvement upon the lantern burner shown and described in U. S. Letters Patent No. 1,276,417, issued to the Handlan-Buck hflanufacturing Company August 20, 1918. The burner shown in said patent is so constructed as to avoid extinction of a flame due to currents of air entering a lantern in which the burner is used, and the object of the present invention is the same as that shown in the patent, with the additional object in view of so constructing the burner as to battle the air currents and to avoid rapid movement of the air toward and around the flame produced in the burner, in order that the flame will burn evenly and uniformly under all conditions.
Figure I is a top view of my burner on a lantern font.
Fig. II is a side elevation of the font and lower portion of the burner, the upper portion of the burner being in vertical section.
Fig. III is an elevation of the upper portion of the font, the burner being partly in elevation and partly in vertical cross section.
In the drawings A designates a lantern font surmounted by a burner E, the body of which may be of any ordinary construction. The burner includes a wick tube 6 through with the wick C extends.
D designates a cup-shaped flame spreader secured to the upper end of the wick tube Z). This flame spreader is provided with parallel side walls 1, in each of which is an aperture 2 through which air may enter the flame spreader to supply oxygen to a flame burning from the wick C. Each of the side walls of the flame spreader has fixed to it a downwardly and outwardly flaring baffle wing 3, preferably perforated. The parts thus far described are shown in the patent herein mentioned and no invention for such parts, per 86, is herein'claimed.
It has been found in the use of a burner having only the correlated parts just described, that when severe motion is imparted to a lantern in which the burner is used, rapidly moving currents of air induced by the motion of the lantern enter beneath the baflie wings 3, moving both laterally and vertically, and pass into the flame spreader D to the detriment of an even burning flame within the flame spreader. To avoid rapid flow of air currents into the flame spreader which interfere with the flame, I have in my present invention incorporated in the burner certain baffle members which restrict and retard the flow of air currents, with the result of overcoming the interference with the burning of an even flame.
At each end of the burner is a transverse baflle web (1 which preferably spans the space between the flaring baflie wings 3, said baffle webs being usually of the same height as each baffle wing, so that they prevent lateral or horizontal movement of air between said baflie wings and the opposing walls of the flame spreader. 5 designates a horizontal baffle plate located beneath the flame spreader D and preferably formed with vertical extensions 6 which are suitably secured to the baffle webs 1. This baffle plate 5 surrounds the wick tube C beneath the flame spreader and extends from the latter toward the lower edges of the baffle wings 3, from which it is separated sufiiciently to permit of the upward movement of air between the sides of the baflle plate 5 and the inner faces of the baflie wings 3;
Provision is therefore made for the limitation of the amount of air permitted to ascend from beneath the burner to the flame spreader D, and such air as does ascend from beneath the burner must necessarily pass through the restricted passageways between the baflie wings 3 and the baffle plate 5, to be deflected by said baffle wings into the flame spreader. Therefore rapid and ununiform ascending air currents enter the flame spreader in an approximately horizontal direction, and upon entering the flame spreader do not materially interfere with the burning of the flame therein as they would it they were permitted to enter the flame spreader in a vertical direction and pass rapidly upwardly therein.
At each end of the flame spreader D is an outwardly flaring tip 7, these tips providing for elongation of the flame above the burner.
I claim:
1. A burner comprising a flame spreader having apertured walls, balfle wings extending downwardly from the upper portion of said flame spreader and overhanging the apertures in said walls, and baflie webs between said baflle wings extending downwardly from said flame spreader.
' 2. A burner comprising a flame spreader having apertured walls, baflle wings extending downwardly from the upper portion of said flame spreader and overhanging the apertures in said walls, and baflie webs spanning the spaces between said baflle wings and extending downwardly therebetween from said flame spreader.
3. A burner comprising a flame spreader having apertured walls, baflie wings extending downwardly from the upper portion of said flame spreader and separated from the apertured walls of the flame spreader, said baflie wings overhanging the apertures in said walls, and baflle webs extending downwardly from said flame spreader between said baflle wings.
4. A burner comprising a flame spreader having apertured walls, baflle wings flaring downwardly from the upper portion of said flame spreader and overhanging the apertures in said walls, and baflle webs extending downwardly from said flame spreader between the end portions of said baflie wings.
5. A burner comprising a flame spreader having apertured walls, baflle wings extending downwardly from the upper portion of said flame spreader and overhanging the apertures in said walls, baflle webs extending downwardly from said flame spreader between the end portions of said baffle wings, and a horizontal baflle plate beneath said flame spreader.
6. A burner comprising a flame spreader having apertured walls, baffle wings extending downwardly from the upper portion of said flame spreader and overhanging the apertures. in said walls, baffle webs extending downwardly from said flame spreader between the end portions of said baflle wings, and a horizontal balfle plate beneath said flame spreader, said baflile plate being separated from said baflle wings.
7. A burner comprising a wick tube, a flame spreader having apertured walls, said flame spreader being secured to said wick tube, baifle wings extending downwardly from the upper portion o1 said flame spreader and overhanging the apertures in said walls, baflle webs extending downwardly from said flame spreader between the end portions of said baflle wings, and a baifle plate surrounding said wick tube and extending therefrom toward said bafie WIDOS.
8. A flame spreader secured to said wick tube, said flame spreader having apertured walls, baflle wings flaring downwardly from the upper portion of said flame spreader and overhanging the apertures in said walls, baflle webs extending downwardly from said flame spreader between the end portions of said ballle wings, and a baflle plate surrounding said Wick tube and extending horizontally therefrom toward said flaring baflie wings.
9. A burner comprising a flame spreader having apertured walls, baflle wings extending downwardly from the upper portion of said flame spreader and overhanging the apertures in said walls, and a horizontal baflle plate beneath said flame spreader.
In testimony that I claim the foregoing I hereunto affix my signature.
