LAMP-BURNER.

SPECIFICATION forming part of Letters Patent No. 316,422, dated April 21, 1885.

Application filed February 23, 1884. (No model.)

To aZZ whom it may concern.-

Be it known that I. GEORGE H. WrLsoN, a citizen of the United States of America, residing in the city of St. Louis, and State of Missouri, have invented certain new and useful Improvements in Lamps, of which the fol lowing is a specification, reference being had therein to the accompanying drawings.

My invention has reference to lamp-burners of the Argandtype; and its object is to secure in a cheap and compact device capable of being attached to any lamp all the excellences which are now found only in the best and most expensive lamps. To this end it provides means for feeding air to both sides of the wick to aid combustion, for raising and lowering the wick evenly and without catching, for promoting the circulation of the oil,

and for spreading the flame and producing a white light. I

In the drawings which accompany and form a part of this specification, Figure l is a sectional elevation of my improved burner. Fig. 2 is a View, partly in section, of the wick-carrier and the adj listing-wheel, illustrating also the manner in which the wick is carried past the air-in1et tubes. Fig. 3 is a plan of the carrier, and Fig. 4 is a similar view of. the bracket or support for the flame-spreader.

The outer case, A, of my burner has two rows of air-inlets, A A as shown, separated by the partition a. Each row of air-inlets consists of a series of perforations extending horizontally around the burner. Secured within the case by friction or other means is the burner-tube A, which has an outer screwthread where it extends below the case for attaching the burner to a lamp. A central airtube, H, connecting with air-inlet tubes or passages G G, is secured within the tube A by soldering or otherwise securing the said inlet-tubes G G into aperturesin the said tube A. The wick, which, in practice, is made of two ordinary fiat wicks of the proper width, is supported between the tubes A and H. A wick-adjusting tube or carrier, I, having at each end inwardly-projecting teeth I) b, which enter the wick, holds the wick in position, and an ordinary thumb-pinion provided with a shaft, K, and a thumb-wheel, g, and properly supported in the burner, acts on the perforations I of the carrier I to raise and lower the carrier and the wick. The perforations of the carrier I are arranged in vertical rows, as shown. The perforations also serve the purpose of giving free circulation to the oil, and so prevent the charring of the wick, which sometimes takes place when the carrier is solid.

I have shown a carrier provided with slots or recesses I P, the top of the slots being arranged to rest in the lowest position of the carrier on the air-inlet tubes G G; but I may make the tube I shorter, and dispense with those portions which extend below the top of said inlet-tubes. \Vhile I prefer the form shown and find it of great advantage in connection with the two rows of teeth 0 for carrying the wick past the inlet-passages with out obstruction, yet that part of my invention which consists in providing teeth at the top and bottom of the carrier would be of equal.

advantage in constructions where the slots or recesses would serve no function.

The air passes to the outer side of the wick through inlet A and passage m, and to the inner side of the same through inlets A and G G and air-tube H. To prevent the air from passing across from one inlet, G, to the other, and so causing a downward draft through the tube H, I place a diaphragm, J, as shown,between the two inlets to deflect the air upward.

A frame consisting of tube E, arms E, and ring H supports a deflector, F, and is itself supported on the top of the tube H by a flange on the upper end of the ring, H. A shoulder, F, on the stem F of the deflector, forms the means for supporting the same on the end of the tube E.

The chimney-holder e,forming a part ofthe outer casing of the burner, is provided with perforations f for admitting air to the passage m.

I am aware that wick raiscrs or carriers have been used or proposed having inwardly-prm jectingteeth at two points between the extremities; but in such cases the introduction and adjustment of the wick are difficult, and it is impossible to have the teeth as close together as they may be when the material at the edges of. the extremities is bent inward, and formed into teeth, which, moreover, may

be conveniently and economically done, and the greatest efficiency obtained in that the draft upon the wick either upward or down-' ward takes place opposite the extreme ends of 5 the carrier. Having now described my invention, what 7 I claim is- 1. In a 1amp-burner, a wick-adjusting tube or carrier providedwith teeth projecting ill- 10 wardly from the top and bottom edges thereof, substantially as described.

2. In a lamp-burner, a wick-adjustingtu'be or carrier, I, having one or more slots, 1", and

provided with inwardlyprojectingteeth at its top and bottom, in combination with an airtube provided with one or more air-inlets, G, whereby the wick is drawn upward with the carrier in the usual way and downward positively past the air inlet or inlets, substantially as set forth.

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