IMPROVEMENT 'IN LAMP-BURNERS.

The Schedule referred to in these Letters Patent and making part of the same.

To all tuhom it ma/y conce/rn AFigure 1 is a vertical section of said lamp-burner,

transversely ot' the shafts of the wick-raisers.

Figure 2 is a similar section of the burner, at right angles to the section, jig. l.

Figure 3 is a sectional plan, .at the line a: x.

Figure 4 represents the wick, in the shape it assutiles in the burner. l

Similar marks of reference denbte the same parts.

My invention relates `to a burner, in which a flat wick is introduced up through the lower end of the wick-tube, in a dat, folded condition.

The wick is opened, to passa lateral openn g, through which air is admitted to a central tube, and then the wick is brought into a circular form, so that the flat, folded wick is employed in an argand-burner.

The wick-raiser acts upon the wick, when in the folded condition, and thc air is directed upon the outside of the flame, by the glass chimney, the interior draught being taken from within a conical chamber, having air-inlet openings at or near the base.

In the drawinga is the base of the burner, which is to connect with the reservoir, by a screw, or otherwise.

Through the base, a, the lower part b of the wicktube passes.

The wick-tube, at this point, is of a size and shape to pass the wick c in the double, 'or folded condition, illu'strated in g. 4.

A; his part of the wick-tube, I apply the wick-raisers These wick-raisers are made of pairs of pointed whee1s,.set on the shafts e e', so thatthe points lock into each other; and the wheels, and shafts turn together, although the power torotate is only applied by the button f, to the shaft e. y,

l'.)lhese wick-raisers act through` slots in the wicktu e. i

This wick-tube is extended near the top of the burner, at which point it is cirpular.

Between the circular top and the lower part of the wick-tube, said wick-tube is spread, to conform to the external shape of the wick, as it is opened out from its folded form, and brought into a circular shape outside of, or around the central air-tube g.

This central air-tube g is, at its upper end, circular, and extends downward, and curves out sidewise, in an elongated, or attened form, as shown at h, the area of the elongated opening corresponding, or nearly so, to thatof the roundfupper end of the airtube; and at the point where theielongated portion of the air-tube g passes out through the side of the tube b, the parts are to be united rmly, to prevent the escape of liquid hydrocarbon, or the vapors thereof.

Around the wick-tube b, there is a conicalI case, lc, v that is either perforated at its lower end, or connected otherwise by arms, or braces, with the wick-rubs b or hase, a, so that air can pass freely into the space, and go up through the central air-tube g.

Around this casale the chimney-bolder Z isplaced.

This is made so as to sustain the glass chimney fm., and allow a current of air to pass up between the chimney m and the conical caseta, to produce a perfect combustion on the outside of the dame.

The glass chimney should have ya contraction, or neck, to deflect the air upon the outside of the flame.

I do not claim a flatfwi'ck in a lamp-burner, that bends said wick into a circular form, for an argandflame, as that has before been employed in the lamp of T. Adams, patented September 16, 1'868; nor do 1 claim two or more wicks brought together into an argand-form, (see Letters Patent granted to me, February 25, 1868, and Youngs Vcstaflamp, described in Webster and Parks Encyclopedia of Domestic Economy, page 190, figure 1391*.)

In my present lamp, the wick is of one piece of materialfolded together where the wick-raisers act upon it, and then spread, to pass the'air-tube of thel argandburner, which is not the case with either of the beforenamed lamps, and hence the wick can be raised with uniformity all around.

What I claim, and desire to secure by Letters Patent, is-

rIhe lamp-burner, constructed with the wirk-tube b, air-tube g, and wick-raisers, in the manner specified, so that the dat wick passes in a folded 'ondition, through the wck-tube and wick-raisers, and is then pread into a round form at the argand-ame, as speci- Dated this 22d day of March, A. D. 1869.
