IMPROVEMENT IN LAMP-BURNERS.

TO ALL WHOM IT MAY CONOERN Be it'known that I, E. B. REQUA, of South Bergen, in the county of Hudson, and State of New Jersey, haveinvented a new and improved liamp-Burner;A andI do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings forming part ofthis specification. Y I

T his invention relates to a new and improved lamp-burner for burning coal-oil or petroleum, and of that class in which a cylindrical draught-chimneyis used, and a great portion of the ivick-tube exposed.

The present invention consists in a peculiar construction of the cone or deector with a perforated plate, as hereinafter fully shown and described, whereby three very important results are obtained, to wit: rst, the supplying the base of the llame within the cone with a requisite amount of oxygenf; second, the supplying the upper part of the ame above `thecone with a requisite amount of oxygen; and third, the keeping of the wicktube in a proper cool state, so as to prevent a too rapid evaporation of the oil. These three conditions being attained, a brilliant illuminating flame is the result, and explosionseieetually guarded against. In the accompanying sheet of dr'awings- Figure 1 is a side sectionalpview of Imy invention, taken in the line a: x, fig. 2.

Figure 2, a horizontal section of the same, ltaken in the line y y,pig. 1.

- Figure 3, a detached plan or top'view of the perforated plate.

Similar letters of reference indicate corresponding parts;

A represents a. rim, which is connected by radi-al plates, a, with a central hub, b, in which the wick-tube c is fitted, and through which it passes, the wick-tube extending a considerable distance above the hub, as shown in tig. 1. The radial plates a are perforated so as not to impede the passage of air upward within the chimney, and the rim A is provided with short upright projections to prevent the lateral displacement of the glass draughtchimney, which rests on the rim A, as shown in red in g. 1.

B represents a perforated cup-shaped plate, the diameter of which is equal to the internal diameter ofthe chimney, the edge of B being notched, so as to admit of the passage of-air upward between B and the chimney, as indicated by the arms 1, (see g. 1.) The cup-shaped plate B is attached to the radial plates a by uprights 01X, which are of such a height as to leave a large portion of the wick-tube c exposed, as shown in iig. 1. The central portin of B at its under side is concave, a's shown at d, and this concave 'surface detlects air against the wick-tube c, as indicated by arrows 2,' keeping the latter cool, and preventing a too rapid evaporation of the oil in the lamp. The wick-tube c passes loosely through B, a space being allowed all `round it for the air to pass through. i

C represents a cone or deilector, which is fitted upon the perforated cup-shaped plate B, and is perforated all around at its edge to admit of the escape of air therefrom, as indicated by arrows 3, the cone or deilector being a'triiie less in diameter than B, in order that a space may be allowed for the escape of air.

The air that supplies the llame above the cone or defleetor C is indicated by the arrows 1 and 3, and the air that supplies the base of the dame within the con'e or detiector is indicated by thearrows 4, and passes through the perforations in B, and around the wick-tube c, and is deected upon the lower part of the llame by the deiiector, as will be fully understood by referring to fig.. 1. Y

By the construction and arrangement of parts above described, a brilliant illuminating dame is obtained, the air being directed upon the dame at such points and in such quantities as to insure perfect combustion. In

other burners ofthis class, the means employed for deflecting the air upon the flame are quite suicient; in fact,

so far as'I am aware, none have been devised in which the principle of a cone or detlector and a perforated under cup-shaped plate'have been adapted for this special class of burners. So far as supplying the flame properly with air is concerned, I have combined all the advantages possessed by the common burner, and` at the same time retain all the advantages of the more modernlclass burner, to wit, the keeping of the lower part of the chimney cool, so that it can be readily handled and removed at any time, and the prevention of too rapid an evaporation of the oil.V I

Having described my invention, what I claim as new, and desire to secure by LettersPatent, is-

l. The perforeterl-cup-sliaped plate B, provided with an under concave surface d, through which the wicktube c passes loosely, substantially as and for the purpose specified. v

2. The lower rim A, with'tlxe Wick-tube c attached, in Connection with the perforated cup-shaped plate B and 4cone or deeotor C, all arranged substantially in the manner as and for the purpose specified.
