ARGAND LAMP.

SPECIFICATION forming part of Letters Patent No. 266,45*?, dated October 24, 1882,

Application tiled September 6, 1582.

To all whom it muy concern: l

Beitknown that I, JOSEPH FUNCILOF Tompkinsville, in the county of Richmond and State ot'New York, haveinvented an Improvement in Lamps, ot' which the following is a specification.

In my Patent No. 198,600 I make use of an air-tube with a ferrule sliding thereon, that receives the lower end ot' the cylindrical wick, and there is a pin proiectingt'rom the thimble into a helical groovein the tube that surrounds the wick, and the slotted tube that is revolved to raise and lower the wick is outside the wick and inside the grooved tube.

In my present improvement I make the wicktube ot' thin sheet metal, and bend upon it a hollow helical rib, forming on the inside the wick-raising groove; and I combine with this an air-well passing down into the lamp-reservoir, so that the air to the central air-tube first descends outside the wick-tube; and I provide an air-distributer that is connected with the slotted wick-raising tube, and a pinion to revolve the same. This air-distributer is below and separate from a movable spring chimneyholder, and rests upon the upper perforated portion or gallery' ofthe air-well. By thisimprovemcut I am enabled to raise and lower the wick-tube with ease and accuracy, and to remove the chimney-holder and chimney without disturbing the other parts, thereby7 giving increased facility for cleaning the burner in this class ot'lamps, because by removing the spring chimney-holder the air-distributer becomes accessible and can be wiped oft' and kept clean.

In the drawings, Figure l is a vertical section of the lamp complete. Fig. 2 is an elevation of the wick-raiser and air-distributcr detached. Fig. 3 is a. detached section ofthe chimney-holder, and Fig. 4 is a plan of the lamp with part ot' the chimney-holder removed.

The air-Wella is provided with ascrew atl, by which it is screwed into the collar of the lampreservoir. At the top of the air-well is an enlargement or gallery, b, that is perforated at 2 for air to pass into the lamp.

rlhe air-tube c and wick-tube d are united together at their bottom ends to form an oilholder for the wick, and one or more tubes, 0,

passing through the oil-well, allow the oil from (No model.)

the reservoir to run into this oil-holder. The wick-tube d is ot' thin sheet metal, with a rib, i, pressed up in it tov form the wick-raising screw or helix. The. lamp does not become as much heated with a thin sheet-metal screw as it does when the metal is thick enough for the screw to be cut in it.

rIhe thimble It receives around it the lower end ofthe cylindrical wick It', and there is a projecting pin, 5, that passes into the helical or screw groove in the wick-tube d.

The wick-raiser tube l is slotted to pass at each side ofthe pin 5, and its upper end surrounds the wick., and is at the same level, or nearly so, as the top ot' the air-tube o. This tube Z is provided with a perforated ange or skirt, m, forming an air-distributer, the edge ot' which is within the gallery b, and this airdistributer and wick-raiser tube l can be rotated by the thumb wheel n, shaft 0, and pinion p, that is supported upon the galleryb, and the pointed teeth otthe pinion p enterthc outer circular row ot' holes in the air-distributer to revolve the same in either one direction or the other and raise or lower the wick.

rIhe chimney-holding spriugsrstand up from the chimney-rest s, and there is a circular downward ange, 7, that surrounds the upper part of the gallery 1)so that the chimney and chimney-holder can be lifted olf when desired. The ilange or rim 8 serves as aholder for a globe, it' the same is used.

The central stem, t, and button a are applied inside the Argand flame, and the neckcl1imney o outside the llame, so that the air is t'orced into contact with both sides of' the Argand flame. The button may be either above orbelow the neck ot' the chimney.

I claim as my invention- 1. Thecombination, in a lamp-burner, of the air-well, the air-tube c, and the wick-tube7 united at their lower ends, the oil-supply tubes, the t'errule and its` pin, the wick-raiser slotted longitudinally, the gallery at the top end ot' the air-well, the air-,distributer connected with the wick-raiser and passing inside ot' the gallery, and the thumb-wheel, shaft, and pinion, operating upon the air-distributer to revolve the same and raise and lower the wick, substantially as set forth.
