FLAT-WICK LAM P-BURNER.

SPECIFICATION forming part of Letters Patent No. 736,545, dated August 18, 1903.

Application filed May 11,1903.

$0 aZZ whom it may concern:

Be it known that 1, WILLIAM C. QUIGLEY, a citizen of the United States, residing at Marion, in the county of Marion and State of Ohio, have invented certain new and useful Improvements in Flat-Wick Lamp-Burners, of which the following is a specification.

My invention relates to lam p-burners,having special reference to burners employing a flat wick, and has for its object to produce a burner in which the currents of air are given a. reflex action as opposed to the strong upward draft now coincident with the burners in use, thus retarding the rise of the vapors and gases and providing for their thorough combustion. My burner therefore by preventing the escape of unconsumed gases and vapors cheapens the cost of the light, because less oil is required to secure a predetermined candle-power, and at the same time the oftensive and noxious odors arising from the burning of petroleum are avoided, thus permitting the use of the inferior and cheaper grades of oil, if desired.

The advantages of myinvention will appear hereinafter and by reference to'the accompanying drawings, in which- Figure 1 is a central vertical section of my improved burner; Fig. 2, a top plan view of the wick-tube, and Fig. 3 a top plan view of the flame-cone.

Referring to the drawings, in which similar reference characters indicate corresponding parts throughout the several views, 1 represents'the base of my burner having the screwthreaded neck 2, which is formed to fit into the neck of a suitable oil-receptacle. The base 1 is bent vertically upward, as shown at 4, and formed with a crimped flange 5, in which are secured the base-plate 6 of the wicktube 7, a flange 8 of an inverted cup 9, and a flange 10 of the outer perforated casing 11. The cup 9 has a slot 9, through which the wick-tube 7 extends.

12 represents the ordinary construction of shaft for adjusting the wick, having the spurred wheels 13 secured thereto to pierce the wick.

The casing 11 is formed with an outwardlycurved portion 14: and a narrower inwardlycurved portion 15, both of which parts are perforated to admit air to the body of the $erial No. 156,655. (No model.)

burner, While above the-curved portion 15 is a vertical annular imperforate wall 16.

' 17 represents the top plate of the burner, formed with a dish-shaped center 18 to fit in the space formed by the annular wall 16. The bottom of said center 18 has a slot 18 therein to receive the wick-tube 7 and perforations 19 to permit the upward passage of air-from the space contained in casing 11. The top plate 17 is extended outside the wall 16 on a horizontal plane to form a rest for the bottom of the chimney 20, said plate having projections21 around its edge that are designed tobe crimped over a lug 22 on chimney-clips' 22, the lower end of said clips being inserted through slots 23 in plate 17 and bent, as shown at 24:, to hold them in place. The plate 17 is provided with a row of perforations 25 just inside the chimney 20 to permit ingress of air.

26 represents the cone, which is seated in the dish-shaped center 18 and has a suitable slit 27 for the passage of the flame. The cone 26 has an outwardly-extendin g bead 28, which is perforated, as shown at 29, while 30 represents a row of perforations extending around the cone 26, approximately on the line of the ends of the slit 27, and 31 a row of perforations on each side of said slit, slightly removed from the edge thereof and parallel therewith.

The top of wick-tube 7 is curved slightly, as shown at 32, so as to make a fan-shaped flame, and has a plate 33 secured on its edge and following the curve thereof. Plate 33 has its ends 34 straight, while its sides 35 are curved outward, the ends 34 being a little narrower than the width of the flame-slit 27, while the center of said plate is considerably wider than said slit. The advantage-of this shape of plate is that the air-currents rising from below are retarded from sweeping into the center of the flame area because of the greater heat and are distributed evenly along the width of theflame, the ease of egress from the slit 7 compensating for the draft in the center, so that the edges of the flame are fed as much oxygen as the center, and a larger flame is the result.

Having thus described my invention, what I claim is- 1. In a lamp-burner, a plate secured to the end of the wick-tube having straight narrow ends and the sides curved outwardly, as and for the purposes described.

2. In a lamp-burner, a flat wick-tube having its top curved, and a' plate secured to the end of the wick-tube having straight narrow ends and the sides curved outwardly, as and for the purposes described.

3. In a lamp-burner, a perforated casing, a top plate having a dish-shaped center to seat in said casing, said dish-shaped center having perforations therein and a slot, a wick-tube passing through said slot,and a cone seated in said dish-shaped center, substantially as shown and described.

4. In a lamp-burner, a perforated casing, a top plate having a dish-shaped center to seat in said casing, said center having a slot therein and perforations, a wick tube passing through said slot having a curved upper edge, a plate on the end of said wick-tube having straight narrow ends and the sides curved outwardly, and a cone having a flame-slit therein, and perforations in said cone, substraight narrow ends and the sides curved outwardly, and a cone having a flame-slit, perforations around the cone and near its base, a row of perforations on each side of said slit and on a line with the ends thereof, and a row of perforations on each side of said slit and parallel therewith, substantially as shown and described.

In testimony whereof I hereto affix my signature in the presence of two witnesses.

WILLIAM G. QUIGLEY. Witnesses:

RAY W. SIMPSON, GEO. A. MCGRATH.
