Specifica'tion of Letters Patent.

Application filed April 20, 1912. Serial No. 692,174.

Patented Jan. 21, rare.

To all whom-"it may concern:

Be it known that I, Gnouon KEARNEY BRADFIELD, a citizen of the United States, and resident of Hackensack, in the county of Bergen and State of New Jersey, have invented certain new and useful Improve ments in Lamps, of which the following is a specification.

This invention relates to lamps in-which wax or wax-like solid illuminants may. be

burned. I

In a wax-burning lamp, since the illuminant, when the lam is not in use, is in solid condition, the wic -tube and Wick cannot be withdrawn from the body of the lamp at this time,'and accordingly the wick-tube is commonly attached permanently to the hottom of the lamp, particularly as this construction permits the heat of'the flame to be transmitted eflectively to the bottom of the,

wax-receptacle, so as to melt the wax therein when the lamp is burning. In a lamp of the construction just described it is necessary for the wick to issue from the side of the wick-tube near the lower end thereof, and,

since the wick 'must bend sharply at this point, more or less difiiculty is encountered in inserting a wick. v

The object of the present invention is to provide a wax-burning lamp with a fixed wick-tube having a lateral outlet near its lower end, this wick-tube being so constructed as to facilitate the introduction of the wick, and to this end I provide the wicktube with one or more deflecting-members bodiment of the invention is not novel. The

lamp comprises the usual cylindrical waxreceptacle 5 with a flat bottom 6 and a top 7. The wax isintroduced through a central opening in the top, which is normally closed nv a cover 8.

I The wick-tube is formed of two channel-.

shap ed sheet-metal members, one of these members comprising a flat web 9 with lateral flangm 10, and the other comprising a similar web 11 with lateral flanges 12. These channel-members are placed together, with the back of the first closing the front of the second, the two members being soldered or otherwise fixed together so as to form between them a passage for the wick, while the flanges 10 act to stiffen and reinforce the tube. :The channel-members are pro- I vided, respectively, at their lower ends with members 13 and 14 bent into horizontal position and soldered upon the bottom 6 of the wax-receptacle, so as to fasten the wick-tube permanently in place.

To permit melted wax to be absorbedby the wick, the parts 9 and 11 of the wicktube are provided with perforations 15' through which the wax may flow. The-heat of the flame is conducted down.- wardly through thewick-tube so as to melt the wax in the usual manner, and to facilitate this action a metal heat-conductor 16 is arranged to partly surround the flame, this heat-conductor having downwardly-extending portions 12 which are inserted within the wick-tube adjacent the edges of the wick 18, as shown in Fig. 2. A wick-raiser 19 of ordinary? form is provided, as shown in Fig. l.

To provide the lateral outlet for the wick, near the lower end of the wick-tube, the part 11 is cut or slitted horizontally and the sheet-metal above and below this cut is bent,

respectively, outwardly andzinwardly so as to form guide members or deflectors 20 and 21, respectively. The deflector 21 extends across the passage in the wick-tube between the flanges 12, so that when the wick is introduced in the tube the lower end ofthe wick, upon engaging this deflector, is direct ed downwardly and outwardly so as to emerge freely from the tube into the posi tion of Fig. 1, and for this reason it is necessary, in introducing the wick, merely to push the end of the wick into the upper end of the wick tubc, and then rotate the wickraiser 19 to lower the wick. When the Wickraiser is turned to raise the wick, on the other hand, the, deflector 20 causes the wick to return freely into the tube, a sharp angle above the wick-outlet being eliminated by the presence of this deflector.

I claim r 1/ A wax-burning lamp having, in combination, a wax-receptacle, and a wick-tube fixed, at itslower end, to the bottom of the receptacle and extending"upwardly through the top 05: the receptacle, the material of ore side of the wick-tube, near the lower end thereof, heing'cut horizontally and inclined outwardly and inwardly above and below the'cut,respectively, so as to provide inelined deflectors to gilide the Wick through the lateral outlet so formed.

fixed, at its lower end, to the bottom hf the receptacle and extending upwardly to the top of the receptacle, the Wick-tube compris ing two chenneLshaped members fixed to gether with the back of one chasing the front of the other, the hack of the letter member being out across, and the metal belew the out lnclniedxnwardly to form a deflector inclosed between the flanges of said member and adapted t0 guide the wick outwardly
