IMPROVEMENT IN I AMP-BURNERS.V

Specitication forming part of Letters Patent No. 176,920, dated May 2, 1876; application iiled January 14, 1876.

To all 'whom it mag/concern: y f 7 Be it known that I, ALBERT ANGELL, of East Orange, county of Essex and State of New Jersey, 'have invented a new and Improved Lamp-Burner, which improvement is fully set forth in the following specilication, reference being had to the accompanying drawing, in which- Figure l represents a side View. Fig. 2 is a vertical central section. Fig. 3 is a horizontal section in the plane :r w, Fig. 2. Fig. 4 is vertical section of a modification.

Similar letters indicate corresponding parts.

This invention relates to a lam p-burner with a center draft,vwhich communicates with the externall air by a transverse channel openingl into the outside air-space which surrounds the wick-tube. The inner wall of the outside airspace forms a slide, which can be adjusted up and down by an oblique slot and a pin, so as to increase or diminish the center draft, and

to regulate the flame. In the top of the wicktube is fitted an absorbent non-combustible or refractory ring, which rests upon a filling of cotton or other fibrous material that extends down in the oil-cistern, so that the non-co m bustible ring is supplied with oil by the fibrous material, while, by its action, said brous material is protected from being burned or charred.

ln the drawing, the letter Adesignates the wicktube ot' my burner, the upper portion ot' which is of a'larger diameter than its lower lportion, and which is provided with a screwnipple, a, -to fit a corresponding socket in the lamp. The upper part of the wick-tube is provided with a cross-channel, b, which communicates, by an opening, o, with thecenter v draft d. 0n the outside of the wick-tube is fitted a sleeve, B, which is provided with a cup, O, for the support of the chimney, and

'with a conical jacket, l), between which and the sleeve B is formed the outside air-space d',`

to which air is admitted from below through holes e. In the sleeve B are holes f,'which open in the air-space di', and, if said sleeve is moved down to the position shown in Fig. 2, said holes coincide with4 the openings of the cross-channel b, and the center draft is in free communication with the air-space d.

In the lower part of the sleeve B is cut an oblique slot, g, Fig. l, which catches over a pin, It, projecting from the wick-tube. If the sleeve is turned round, therefore, it is also raised or lowered by the action of the oblique slot on the pin h, and by turning the sleeve in the direction of the arrow marked on it in Fig. lit is raised and turned so that the openings of the cross-channel are gradually closed, and the center draft is diminished or entirely shut oft'. At the same time, the mouth of the outside air-space is raised above the top edge of the wick-tube, and the ame is reduced or finally put out entirely.

ln the top of the wick-tube is` fitted a ring, E, which is made of an absorbent and noncombustible or refractory material, such as asbestus, or a mixture ot' asbestus and pumice-stone. This ring bears 011 a packing, F, of cotton or other fibrous material, which eX- tends down through the wick-tube into the oilcistern.

If desired, a spring, G, may be introduced, as shown in Fig. 4, to keep the fibrous material in close contact with the absorbent noncombustible ring E.

By the fibrous material the ring E is kept supplied with oil, and, it' the lamp is lighted,

-said ring protects the fibrous material from being burned or charred.

Iithe ring E should ever become choked up or burned out it can easily be removed and replaced by another. 4

What I claim as new, and desire to secure by Letters Patent, is

1. The combination, with the wick-tube A, cross-channel b, center draft d, and pin l1., of a sleeve, B, with air-space d', openings e f, and oblique slot ig, all constructed and operating substantially as shown and described.

.2. The combination, with the Wick-tube A and center draft d, of an absorbent non-combustible ring, E, and a packing, F, of fibrous material, substantially as set forth.

In testimony that I claim the foregoing I ALBERT ANGELI.. [1.. s]
