Letters Patent No. 92,771, dated July 20, 1869.

IMPROVEMENT IN 'LAMP-BURNERS.

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

vTo all vwhom 'it may concern: l

Be it known that I, THOMAS ADAMS, of Hudson City, in the county of Hudson, and State of New Jersey, have invented and made a new and useful Improvement in Lamp-Burners; and I do hereby declare 1868, No. 74,'4'93, in which twowicks are used, the

same passing up around a central. air-tube, having lateral openings so as to form an argaud burner. A

burner ofthis'general character is shown in figs. 1 and 2, in whichy a is the base, to screw to the reservoir;

b is the wick-tube, of a size to pass two wicks laid flatwise tgether;

c care the wick-raisers;

e, the exterior wick-tube, near the flame;

d, the central air-tube, with lateral openings (Pfand f is the cone, directingr the draught and carrying the chimney-holder g.

1n lamps of -this character there is great diculty in inserting the wicks, because the wicks frequently both pass on one side of the central air-tube, instead of parting and going one on each side, and sometimes the corners ofthe wick tum back, and cannot be forced through. i

In order to avoid these difficulties, I apply my invention, which consists in a dividing-plate, extending down from the air-tube into the wick-tube, so as to guide the wicks and open them, so that they will pass,

one on. each side ofthe central air-tube and its lateral openings.

I have shown this plate at h, figs. 1 and 2, asciitending across the wick-tube, from one edge to the other, in order that the wicks may be separately'guided up on opposite sides of the air-tube d.

The eenmal portion of this dividing-plate might be dispensed with, but I find the same preferable in the form shown. A

My invention is also capable of use with the lampe burner set forth in the application of A. NV. Browne, allowed May 4, 1869, in which a fiat wick is employed, the same being folded, and the air Ato the central tube being admitted at one side only; a burner of this general. character being shown in figs. 3 and 4, in which the base and screw a, are shown as fitted with the wicktube b, rising to the circular tube e, around the base of the flame.

c c are the wick-raisers, and d is the central air-tube,

curved downward and sidewise, to form the inlet at (l2.

My improved dividing-plate h is only required at one side of the wick-tube, extending from and below the lateral inlet di, in order to guide the edges alii end of the wick, and cause itto pass correctly on each side ofthe tube fll In this burner, I make the conical enclosure I; to extend down and, unite with the base a, and around the lower end ofi'said cone the air-inlet holes 5 5 are introduced, that allow the passage of air to the tube d.

The chimney-holder g `is lmade removable, and is fitted with a conical sleeve, y', to set upon the outside' of the cone k, and sustain the chimney and holder, but allow these to be removed with great ease to give access lto the fiame for trimming or lighting.

These improvement-s remove objections heretofore found to exist with this class of burners, and give to the argand lamp every facility heretofore possessed by the-at-wick lamps. 'y

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

1. 'Ihe dividing-plate h, introduced within the wick\ tube, and acting to' separate and guide the wick or wicks, substantially as set forth.

.2. The chimney-holder g and tapering sleeve g', in combination with the cone L', to allow the chimneyand holder to be removed from the argand burner, sub-v stantially as set forth.

In witness whereof, I have hereunto set my signature, this 21st day of June, A. D. 1869. l i THOS. ADAMS.

Witnesses CEAS. H. SMITH, GEO. T. PINCKNEY.
