Application filed April 15, 1912. Serial No. 690,730.

To all 1072 0111 it may concern:

Be it known that I, CHARLES E. YVin'rH, a citizen of the United States, residing at \Vaterbury, in the county of New Haven and State of Connecticut, have invented a certain new and useful linprovenieiu; in Lamp-Burners, of which the following is a specification.

My invention relates to burners for kerosene oil lamps, and particularly to such lamps as employ a mantle to be made incandescent by a blue liame of the lamp.

In lamps of this character, the construethe manner of holding the outer air tube in place, and the number of soldered joints, particularly at the lower air inlets, have preventedsuch lamps being wholly satisfactory, either mechanically or commercially, and the object of my invention is to ove come these difficulties.

In carrying out my invention, 1 construct the inner wick tube in one piece and oll sct thelower part from the upper part by a shoulder. which when perforated, becomes a guide for the rack of the wick raiser. I form the arches for the air inlets at opposite sides of the lower portion of the inner wick tube in one, or integrally with said wick tube, consequently the places of union of the arches with the outer wick tube are the only soldered joints, namely, two in stead of four, as heretofore. This construction also provides a most suitable and secure foundation for connection of the pinion and shaft thereof for raising and lowering the wick raiser and wick. The line of these parts is parallel to r. radial line instead of on a radial line, and the teeth of the rack are cut to accommodate the change, consequently the inlet for the air through one arch is less obstructed and less choked than in similar burners heretofore employed.

The upper part or" the outer wick tube is removable. It is provided "with a base and a flanged periphery to the base setting snugly Within a shouldered portion formed between the lower and upper air distributers, which are in one piece, and the parts are provided ith engaging means, all of which is hereinafter more particularly set forth.

In the drawing, Figure 1 is a vertical 50C- tion showing, complete, lamp-burner of my invention with a mantle and part of a chimney in position. 2 is a sectional l l l l l (1 the upper air u .formed in one. and the bottom plate 3 plan at about the broken line as a; of Fig. 1, and .ldig. 3 is an inverted sectional plan. about the broken line 3 g of Fig. 1, and F at a detail hereinafter described.

Similar letters and numerals of reference indicate the same parts in all the figures.

T he inner wick tube comprises the upper portion u and the lower portion (4 between which is formed u shoulder These parts are integral and at the lower end the inner wick tube is closed off by a bottom plate 3, which is preferably an integral part of the air distributers. The outer \v ick tube comprises the lower tube part Z) and the removable upper part c. his upper part is formed integrally with the flanged base 0 and an up-turned flanged periphery c (Z represents the lo er :iir distributor, and ributer. These are formed therewith cue; through for the lower ends of the ii :l outer wick tubes to provide spaces for the wicks. Their union is iinperforaie with a substantially vertical shouldered wall within which is received the flanged periphery 0 of the outer wick tube. the lower part of which comes to :1 seat at the shoulder prepared between the air distributer pow-lions d and (I e is the conical lector having a tlanged base 0 and skirt and ;t represents the chimney holder secured to the upper part of this skirt, so that to all intents and purposes, this conical deflector, its llanged base and skirt, and the chimney holder are in the finished lamp burner substantially integral, as the chimney holder is secured to the other parts. as usual in these burners.

l provide a. bayonet slot 4; in the upper portion of the air distributor (Z and a projection or pin 5 on the skirt of the chimney holder, whereby when the deflector and chimney holder, with the skirt thereof, are placed down over the upper air distributer, the parts may be firmly connected by the projection 5 entering and being held in the slot 4t. 1 further provides projection 6 formed in the union between the upper sir distributor and the lower air distributor, and notch the flanged periphery 0" of the base of the outer Wicktube, cutting away at the same. time, a portion of'the flan ed base 0' to pass me project-ion 6, hence w on the outer wick tube passed' down' its seat at the union of the paris 'of the air earner gaged thereby, and a bracket for the end of'the pinion shaft within the lower .portion of the inner air tube and secured thereto and the shoulder between the parts of the inner air tube perforated for said rack.

5. In a lamp burner, aninner air tube comprising an upper portion and a lower port on of different dimensions, a shoulder integrally connecting and. extending between the lower end of the'upper part and the upper end of the lower part and said shoulder perforated, awick raiser surrounding the upper part of the inner wick tube and a rack bar connected therewith and passing down through the aperture in the shoulder, a pinion and pinion shaft, the

latter located parallel to a radial line, bearings for the shaft and pinion, and the teeth of the rack bar cut in a plane at an obtuse angle to the plane of the rack bar, whereby the rack is readily engaged by the pinion and operated. I

' 6. In a lamp burner, the combination with an outer wick tube provided with opposite openings, of an inner wick tube and ;projecting.walls and arches forming air inlets disposed oppositely and formed integrally with the inner wick tube, and *adapted to pass through the openings in the outer wick tube and to be soldered there to, an upper and a lower air distributor formed in one, and a bottom plate also formed in one therewith and perforated for the intersection of the outer and inner wick tubes, but imperforate so as to form bases or bottom plates to the air inlet arches.

7. In a lamp burner, the combination with an inner wick tube, of an outer wick tube formed of a lower and an upper por tion, and the upper portion provided with a base extending out therefrom, and a flanged periphery, upper and lower air distributers formed in one with an imperf rate part between the upper and lower portions provided with a shoulder, forming a seat for-the flanged periphery of. the upper portion of the wick tube. Q

8. In a lamp burner, 21 wick r aiser sha ft and pinion, with the shaft placed parallel to a radial line from the center of the burner, and a rack bar occupying aplane tangential to the circumference of the inner wick tube and with the teeth thereof formed in one edge at an inclination to the plane of the bar, which brings theends and bases of the teeth intoparallelism with shaft and pinion teeth;
