LAMP-BURNER.

SPECIFICATTON forming part of Letters Patent No. 346,889, dated August 10, 1886.

Serial No. 187.708. (No model.)

To all whom it may concern:

Be it known that I, EBENEZER BLACKMAN, of Brooklyn, in Kings county, in the State of New York, have invented a certain new and useful Improvement in Lamp Burners, of which the following is a specification.

I will describe a lamp-burner embodying my improvement, and then point out the various features in the claims.

In the accompanying drawings, Figure l is embodying my improvement. Fig. 2 is a vertical section of the same, taken in a plane at right angles to the plane of the section in Fig. l. Fig. 3 is an inverted plan or bottom view of the burner, and Fig. 4 is a perspective view of the wick and wick-holder detached.

Similar letters of reference designate corresponding parts in all the figures.

A A designate a wick-tube, which is of annular form, and consists of two cylindrical shells, of sheet metal or tubing, arranged one concentrically within the other. The shell A is flattened at two opposite portions, a, and these two portions converge toward each other downwardly. This tube is mounted upon the bottom of a cupshaped airdistributer, B, and secured thereto. The outer shell, A', of the wick-tube does not extend down to the bottom of the air-distributer B. vAt the lower edge it has an outwardly extending flange, A', at whose outer circumference is a downwardlyextending rim. The flange c' rests upon the forated cylindrical shell, C, which is erected upon the bottom of the air-distributer B. lt will preferably be made of a metal which is a poor conductor of heat. It is concentric with the wick-tube shells A A', but is considerably larger than either.

D designates the wick. It consists of a cylindric upper portion, d, and two strips, d' d2, extending therefrom. Itis secured in a holder, E, consist-ing of a cylindric upper portion, e, and strips e e", extending downwardly therefrom. Thisv holder is perforated longitudinally with rowsof holes. It may be made of any suitablesheet metal, preferably one which is a poor conductor of heat. The wick is secured to it by sewing or otherwise, so that the two areintimatel y connected together. The cylindric portions ofthe wick and wiclcholder fit between the shells A A' of the wick-tube, and the strips of the Wick and wick-holder extend down through the space between the shell A of the wick-tube and shell C, that supports the shell A' of the wick-tube.

There is considerable space out ide of the lower portion of the wick and wick-holder,

,owing to the shell C being of greater size than By rea- C the outer shell, A', of the wick-tube. son of the convergence ofthe portions a of the inner shell of the wick-tube a considerable space is afforded inward of the lower portion of the wick and wick-holder. This results in keeping the burner cool.

Gross-passages A2 are made of sheet metal between the inner shell, A, of the wick-tube and the shell C. Y

Air entering the air-distributer B passes upwardly to the outside of a dame emanating from the wick, and air also passes through the passages A2 to the space encircled by the inner shell, A, of the wick-tube, and thence to the inner surface of the flame.

A plate or diaphragm, A, extends upwardly into the shell A of the wick-tube opposite the cross-passages A2. It prevents air from blowing across from one of these passages A2 to the other.

The outer shell, A', of the wick-tube has an air-distributer, F, affixed to-it. This air-distributer consists of a perforated plate of sheet metal, whose outer circumference is bent downwardly to iit over the upper edge of the airdistributer B.

The outer shell, A', of the wick-tubeis merely supported by the bearing which it has at the lower edge upon the shell C, and by the bearing which the air-distributer F has upon the air-distributer B. It may therefore be lifted off at any time to facilitate theinsertion of the wick and wick-holder, or for any other reason.

A c onoidal deflector, G, is supported upon the air-distributer F. It isV made of sheet metal, and is so formed at the lower portion as to constitute a gallery upon which a chimney may rest, armsg being provided to retain the chimney in position.

A ratchet or star wheel, H, mounted upon a shaft, H', journaled in an extension from the outer shell, A, of the wick-tube, engages with perforations of the wick-holder E. When rotated by a hand-piece, with which the shaft is provided, this wheel will adjust the wickliolder, and consequently the wick, upwardly or downwardly.

I designates a perforated sheet-metal tube extending above the wick-tube and closed yat the top, preferably by a defleetor or button, J, extending not only over but beyond it. It is supported by the inner wall, A,of the wicktube. l

The air-distributer B has at the bottom an externally-screw -threaded boss or neck, b, whereby the burner may be secured to the collar of an oil reservoir'or fount.

It will be observed that the ratchet-wheel H and its shaft H' are arranged in quite an ele vated position, much nearer the top of the wick-tube than usual. This is advantageous, because it provides for adjusting the wick and wick-holder the required distance without ever adjusting'the wick-holder into such position that any part of it will extend below the bottom of the air-distributer B. This is advantageous, because when the wick-holder has not to be adjusted into such position that any part of it will extend below the burner the boss or neck b of the burner may be made of smaller diameter than the wick-holder, so as to ada-pt it to t in a reservoir `or fount collar of small size. The wick will not interfere with the making of the boss or neck I) smaller in diameterthan the holder, because it is so ilexible that it can be bent to pass through asmall passage-way.

The Wick-holder E may have only one of the strips e' or e2. Then it will in effect be a cylindric piece and a rack extending therefrom.

The shell C is in effect part of the wicktube.

By perforating the bottom of the air-distributer B below the inner shell of the wick-tube and securing the tube I in a detachable man ner within the inner shell of the Wick-tube, I provide for removing the said tube I and fil1- ing the lamp reservoir or fount by pouring oil down through the inner shell of the wicktube. Air may also descend through the perforated bottom, and ascend through the same into the inner shell of the wick-tube.

`What I claim as my invention, and desireto secure by Letters Patent, is-

1. In an Argand burner, the combination, with an air-distributer, as B, of an annular wick-tube composed of a cylindric shell, as A, secured to the said air-distributer, and an outer cylindric shell, as A', of a perforated shell, C, within the air-distributer B, larger in diameter than the outer shell, A', of the wick-tube, and forming the lower part of the outer wall of the wick-tube, substantially as specified.

2. In an Argand burner, the combination, with an air-distributer, as B, of an annular wick-tube composed of acylindric shell, as A, secured to the said distributer, and anrouter cylindric shell, as A', of a stationary perforated shell, C, within the air-distributer B, forming the lower part of the outer shell of the wick-tube, and being larger in diameter than the outer shell, A', of the wick-tube,said outer wick-tube sh ell. A', being detachablysupported upon the shell C, substantially as specified.

3. The combiuation,with an air-distributer, as B, of an annular wick-tube composed of a shell, as A, lnounted upon said air-distributer, and a shell, A', aperforated shell, C, within the distributer B, -mounted upon said airdistributer and supporting the said shell A', and an air-distributer, F, secured to the shell A' ofthe wick-tube and resting upon the airdistributer B, and the detlector G, substantially as specified.

4. In a lamp-burner, the combination, with an annular wicktube comprising an inner and an outer shell, and provided near its lower end with a passage whereby air may enter the space encircled by the inner shell, of an air-distributer surrounding the lower portion of the wick-tube and supporting the same, the bottom of said air-distributor being provided with an opening extending through the base of the burner within the inner shell of the wick-tube, and a perforated diaphragm between said opening and the tip of the wicktube, substantially as specified.

5. In an Argand burner, the combination, with an annular wick-tube comprising an inner and an outer shell, of an air-distributer surrounding the lower portion of the wicktube and supporting the same, the bottom of said distributer being provided with an opening within the inner shell of the wick-tube, and a perforated diaphragm between said open.- ing and the tip of the wicktube, substantially as specified.
