To all whom it may concern Be it known that I, CARL A. KLEEMANN, of Erfurt, in the Kingdom of Prussia, have invented, made, and applied to use a certain new and useful Improvement in Lamps; and I' do hereby declare the following to be a full, clear, and exact description of my said invention, reference being had to the annexed drawing, making part of this specification, wherein.,-

Figure 1 is a vertical section of my said lamp, and

a is. a standanhsupportcd by any suitable pedestal ;f

or said lmnp may be sustained by any desired ntena; b is the sleeve on said standard a, clamped thereto by a screw, as usual; y

c is the reservoir; and d is ythe fountain, provided with the valve e, by which vthe fountain is closed while being inverted and entered into the reservoir, as usual.

The cylinder f extends below the orifice for the* valve e, and has a notch, i, at one side of said cylinder, through which. the air enters in small bubbles frequently, and the light is not aieeted by the oil running down.

'g is a pipe, leading from the reservoir c to the burner.

h is the outer cylinder, and k, the inner cylinder of the burner, united at their lower ends, and receiving the drip-cup l.

The inner cylinder k is made of sheet metal, and the screw therein is made by bending or compressing said sheet metal, instead of cutting said screw-thread in the metal. The object of this is to get 'the metal of the `burner as thin and light as possible, in order that it may keep cooler, and not conduct heat down to the coal or similar oil. l Around the tube k is the wickholder m, carrying. the wick n, andthis holder rmtakes the screw-thread in k, so as to raise or lower thewick by the rotation thereof.

o is a cylinder outside the wick, with a slot taking thek projection 1 from m, whereby said wick-holder m is rotated.

p is a cylinder outside of h, and connected with the cylinder o. l

I have shown the cylinder pas extending at the top end slightly down inside the cylinderV h, and notched, to take the projections 2 for rotating the cylinder' o.

Aroundl the wick is a flaring or cup-shaped receptacle, 3, that catches any oil thatmay run down outside of the wick-tube o, and returns the same to the lamp, and prevents any overflow. The chimney-holder lris made as a range of springs,

(see fig. 2,) receiving the chimney s; aud this chimney s is contracted, forming a neck a short distance above the top `of the wick, to concentrate the air 'upon the dame, and aid in perfecting the combustion.

Within the chimney-holder r is the cone q, passing up to near the base of the lflame, and openings are provided, so that air passes between the chimney s -The chimney-holder,l cone, and tube, passing down into the cylinder h, are so connected that they turn together, andv forthis purpose 1 have shown the arms 5, and there are arinlets, 4, in the cone q, to allow the air to pass between the chimney s and\eone q..

This burner does not become heated to any considerahle eictent, because the thin sheet metal of which it is composed is largely exposed to the action of the air, and the air is not obstructed as it ascends to the 'flame through the cone q, and the ameis much more l uniform than in the lainps where the chimney-holder is suspended by rods.

I claim as my invention* 1. An argand wick-tube and springchimney-holder, in 4combination with the cone q, and openings to admit air to pass between4 the cone and the glass chimney, substantiall as set forth.

, 9.v The argan wick-raising mechanismfto regulate` theheight of dame', in combination with the cone,

spring chimneyh'older, and air-inlets between the ehirnfney and cone, to direct vair upon thelame,` substantially asset forth'. l

3. '.lhel-spring chimney-holder, cone q, and openings"l
