IMPROVEMENT IN WICK-RA ISERS FOR LAMPS.

Specification forming part of Letters Patent No. 170,428 dated November 23, 1875; application filed February 8, 1875. v

To all whom it may concern:

Be it known that I, ALBERT ALBERTSON, of Jersey City, county of Hudson, State of New Jersey, have invented certain Improvements in Wick-Raisers for Lamps, of which the following is a specification:

One object of this invention is to provide a simple, compact, and easily-manipulated deice for raising and lowering the wick of an Argand lamp; and to this end my invention comprises a novel combination, with the circular wick-tube of such a lamp, of an internally screw-threaded sleeve carried by a supportingannulus working in guides formed in the circular base of the burner, whereby an axial movement communicated to the annulus will give a corresponding movement to the collar, so that the screw-thread ot' the latter, cutting or compressing the wick, will raise or lower the same by its direct action thereon. Another object of my said invention is to enable the wick to be adjusted without removing from its normal position any portion of the lamp or burner and to this end my said invention further comprises the combination of internallyprojecting studs formed upon the removable cone of the burner, with one or more radial or ontwardly-projecting studs formed upon the annulus carrying the internally-threaded collar, whereby an axial movement given to the cone is communicated to the annulus, and, oi"

course, to the collar, thereby securing the result desired. Another object of my invention is to enable the wick to be raised or lowered without danger of burning to the fingers of the operator; and to this end my invention further com prises a rin g of non-conductin g material attached to and arranged around the cone of the burner, so that by grasping the said ring the cone, and consequently the parts operated thereby, may be moved at will without subjecting the fingers to more than normal temperature. 7

Figure 1 is a central vertical sectional view of a lamp-burner embracing the several features of my invention. Fig. 2 is a plan view of the same. Fig. 3 is a horizontal section, inverted, of the same, taken at the line 00 x of Fig. l. v

A is the cylindrical base of the burner, provided in any usual or suitable Way upon or in connection with the usual oil-reservoir or body of the lamp, the said base being provided internall y with two inwardly-projecting parallel flanges, a, which form circular guides for the outwardly-turned lower edge a, of an annulus, B, the upper edge of which is turned inward, as shown at b, and joined to the upper edge of aisleeve, O. v 7

As a modification of this part of the struc ture of my improved burner, and answering the same purpose, a single turned-up flange may be formed upon the outer wick-tube, s

thereby transferring the bearing of the annulus from the baseA to the aforesaid outer wick-tube, but in nowise changing the principle of the device.

The space between the sleeve 0 and the upper part of the annulus B is occupied by the upper part of the outer wick-tube D, while. the sleeve 0 is fitted within the latter, as show tat Fig. 1, there being a sufficient space, ,0, bct'i'veen the sleeve and the inner wick-tube E, to permit the passage of the wick therethrouglnas in the ordinary arrangementof the wick of an Argand burner. The sleeve 0 has formed in or upon its inner surface a clearly-defined screw-thread, so that, as the wick is compressed upon the inner or central a tube E by the said sleeve, the thread of the sleeve will cut or press into the wick to form, asit were, a counter-thread thereon, so that the axial or turning movement of the sleeve in one direction or the other will raise or lower the wick by the screw-like action exerted thereon by the thread of the sleeve. The air for the center of the flame, when the burner is in use. passes, of course, up through the inner wick-tube E, the disk F being supported at a suitable height above the top of said tube to cause the proper distribution of the air as it rises to the flame. G is a removable cone, slipped upon the upper edge of the base A, and clasping the same with sufficient force to insure its retention in place. Projecting inward from one or more sides of this cone is a pair of studs, one of which is indicated at f in Fig. 1. These studs interlock with one or more studs, 9, projecting radiallyfrom the an;

nulus B so that an'axial or turnin g movement given to the cone will communicate a like movement to the annulus, and thence to'the sleeve, the operation of the latter for adjusting the wick from the outside of the burnerbein g thus provided for, at the same time that due provision is made for the removal of the cone when occasion requires. 11 is a ring, of wood -or other bad conductor oflheat, arrangedconcentric with the cone 0, and connected therewith by radial spurs m, as shown in Fig. 2. Thisw noneconducting ring remains comparar tively cool, notwithstanding the contiguity of the cone and other parts of the burner permits the convenient turning of the cone in the adjustment of the wick without liability of burningl thefingers of theoperator.

What aIclaima-smy invention isi 1. The internally screwthreadediisleeve carried by the supporting-annulus B, working in the guide a of the baseA, in combination with the inner and outer wicbtubes D E, substantially as and iortthe purpose set forth, a

2; The internally projecting studsfojnthe removable cone G, in combination with the radial stud g on the annulus B, carrying the i threaded sleeve 0, substantially as and for a the purpose set forth.

3. The non-conducting ring H, concentric with and attached to the removable cone Gr,

substantially as and for the purpose set forth.
