BURNER FOR PETROLEUM GLOW-LAMPS.

SPECIFICATION forming part of Letters Patent N 0. 615,067, dated November 29, 1898. Application filed November 5, 1897- Serial No. 657,503. (No model.)

To aZZ whom it may concern.-

Be it known that I, GEORG KRON, civil engineer, of Hejbergsgade 16, Copenhagen, Denmark, have invented certain new and useful Improvements in Burners for Petroleum Incandescent Lamps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention has relation to burners adapted for use with petroleum-lamps producing a Bunsen flame, for the purpose of rendering incandescent the usual and wellknown mantle; and among the objects in view is to provide a burner whereby a steadilyburning Bunsen flame without smoke is produced, thus providing against the smoking or blackening of the mantle.

The invention consists in the novel construction, arrangement, and combination of parts, as hereinafter fully described, illustrated in the drawings, and pointed out in the appended claims.

In the drawings, Figures 1 and 2 are vertical sectional views illustrating different constructions of the invention.

The wick a is in a well-known manner inclosed in a wick-case formed by two concentric tubes. Above this is placed a cap d of such a shape that a narrow ring-shaped interval f is formed between the upper edge of this cap and a central burner-disk e, the said interval being just above the upper end of the wick.

The purport of the invention is to cover the upper edge of the wick wit-h the uppermost bent edge 9 of a cap or casing h pushed over the wick-case. This arrangement has a double object. In the first place the upper edge of the wick is kept smooth and the fluid soaked up evaporates from the inside of the wick only. Asmoking flame which would blacken the mantle is avoided, as projecting points of the wick are prevented. In the second place the gases developed on the inside of the wick have a winding and consequently longer way to travel before they reach through the aperture f, and a more thorough mixing takes place with the air passing the wick-case on the outside as well as on the inside.

In the arrangement shown in Fig. l the cap or casing it rests upon the wick and is screwed up and down with it, while in Fig. 2 the cap or casing it rests upon a flange t' in the cap 61, and in this case the wick must be screwed up against the bent edge g of the cap or casing. I

The lamp is lighted after the part with the glass, glow-net, cap, and cap or casing It has been lifted so high that access is gained to the wick. When the said parts are again lowered and the wick screwed up, the flame is transformed into a Bunsen flame, which brings the net to incandescence.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is l. A burner for lamps of the character described, consisting in the combination with a wick-case, of a cap d, having an inwardlybent edge, a disk 6, arranged to form a circular space or interval f, between its edge and the said edge of the cap in line with and above the upper end of a wick contained in the wick-case, and a cap or casing h, arranged over the wick-case between the latter and the cap d, and having an inwardly-bent upper edge 9, lying directly over the upper end of a wick, said edge 9, inclosing an annular space which is of less diameter than that of the disk 6, whereby to cause the flame to take a circuitous passage from the wick through the space f, and the said cap h, being adapted to leave a space between edge g, and the upper end of the wick-case.

2. A burner for lamps of the character described, consisting in the combination with a wick-case, of a cap d, having an inwardlybent upper edge, a disk 6, arranged to form a circular space or intervalf, between its edge and the said edge of the cap in line with and above the upper end of a wick contained in the wick-case, the cap or casing h arranged over the Wick-case between the latter and the cap d, and having an inwardly-bent upper edge g, lying directly over the upper end of a wick, said edge g, inclosing an annular In testimony that I claim the foregoing as space which is of less diameter than that of my invention I have signed my name in presthe disk 6, whereby to cause the flame to take a circuitous passage from the wick through ence of two subscribing witnesses. the space f, and said cap h being adjustable GEORG KRON. 5 vertically by the wick to leave a space be- \Vitnesses:
