LAIVI P-BURN ER.

SPECIFICATION forming part of Letters Patent No. 640,981, dated January 9, 1900.

Application filed .Tuly 19,1899. Serial No. 724,358. (No inodeLl T0 alt whom t may concern:

Be it known vthat I, FRANK THEODORE WIL- l LIAMS, a citizen of theUnited States, residing at Meriden, county of New Haven, State of Connecticut, have invented certain new and useful Improvements in Lamp-Burners', of which the following is a full, clear, and exact description.

My invention relates to lam p-burners; and it consists in the novel construction and arrangement of parts thereof hereinafter fully described.

Among the chief objects of my invention are to prevent the Iiickering of the flame, to pro# mote combustion, and to also'aid in lighting.

In the drawings, Figure l is a Side e1eva-` tion of a lamp-burner, showing the spreader in dotted outline.` Fig. 2 is a longitudinal section of the burner, the parts being in position for burning. Fig. 3 is a sideelevation of the parts in substantially the position shown in Fig. 2, with the side broken away to show the construction and arrangement of the internal parts. i 4

It will be observed that the drawings illustrate that type of lamp commonly known as a central-draft7 lamp, in which a draft of air is supplied in the well-known manner through an inner wick-tube to be hereinafter referred to, the air supplied in this manner being divided in small currents by a suitable spreader,as G. (Illustrated in dotted outline.)

A is the top of a lamp-fount.

B is the outer wick-tube.

C is the inner wick-tube.

X is the wick.

D is the perforated air-supply skirt.

E is the chimney-gallery. E are legs connecting said chimney-gallery with a sliding tube F, which loosely surrounds the outer wick-tube B so, that it may be raised and lowered. Since the chimney-gallery E is supported by the tube F, the raising or lowering of thelatter moves the former in a corresponding manner. The upper edge of the tube F is preferably iiared outwardly, as at f. The normal position of the outer tube F is such that when the various parts of the burner are in position for burning the said Iiared end f stands substantially on a level with the upper end of the wick-tube B. Hence the air entering through the perforated skirt D and rising to supply oxygen to the flame is prevented fromstriking directly against the root of the ame when the lamp is first lighted,

serted underneath the gallery and throughf openings F in the tube F,fa`djaceut the side edge ot the wick Were it not for these openings F it is obviousthat the only method of lighting the lamp wouldbe to remove the l. chimney (not shown) and light in theordi` nary way.4 By this arrangement, however, I

am permitted, without removing the shim-1` ney, to gain ready'access to the wickfor the purpose of lighting the lamp. `As shown in f Fig. l, a slot F2 may be formed inthe tubeF `and a stud B' may becarried by thetube B in such manner as to project intosaid slot. By providing notches in the side of the slot F2 or, for example, making the slot L-shaped, as shown in Fig. l, the tube F when in its raised position may be turned slightly, so that the stud B will engage in the offset portion of the slot, thus holding thechimney and the chimney-gallery in the lifted position, for the purpose previously referred to. When the wickhas been lighted, the chimney-gallery E should be restored to its normal position, as indicated in Figs. 2 and 3.

Obviously the number and shape of the openings F is immaterial, as is also the provision of the means for holding the chimney-gallery in its elevated position. These and other minor changes I contemplate, and it should be understood that it is my intention that variations frorn the specific construction shown and described may be made without departing from the spirit or scope of the invention.

While I have shown and described what is commonly known as a central-draft lamp, it is obvious that my invention might be modilied and adapted to lamps that are not of' the central-draft type, in which event an inner wick-tube might not be employed.

What I claim is- IOO In a lamp-burner in combination, an outer Wick-tube, another tube loosely surrounding the saine, the upper edge of the lastnained tube being located on approximately the level of the outer Wick-tube When the parts are in their normal operative position, the upper edge of said surrounding tube being flared outwardly adjacent the base of the llame, an

opening in the side of the outermost tube, and mea-ns to permit said outermost tube to be 1o raised and held in an elevated position.
