IMPRDVEMENT IN LAMPS.

Specification forming Apart of Letters Patent No. 37,867, dated March 10, 1863; Reissue No. 3,068, dated August 4, 1868.

To all whom 'it may concern:

Be it known that I, CARL A. KLEEMANN, of Erfurt, in the Kingdom ot' Prussia, have invented, made, and applied to use a certain new and useful Improvement in Lamps; and I do hereby declare that the following is a full, clear, and exact description of my said invention, reference being vhad to the annexed drawing, making part of this specification, wherein- Figure l is a vertical section of my said lamp; and Fig. 2 is' a sectional plan of the burner at the line :r Fig. 1.

Similar marks of reference indicate the same parts in both figures.-

My invention relates to a lamp adapted to burning coal-oil, kerosene, or other` oils, either pure or mixed with benzine or other material; and consists in an improved means for delivering the oil from the reservoir, and an improved burner adapted to burn the coal-oil withoutheating the lamp and without any risk of the oil overflowing.

In the drawing, a is a standard supported by any suitable pedestal; or said lamp may be sustained by. any desired means. bis the sleeve on said standard a, clamped thereto by a screw, as usual; c is the reservoir, and d is the fountain, provided with the valve e, by which the fountain is closed while being inverted and entered into the reservoir, as usual.

as the oil burns down, a large sized bubble of air enters at the lower end of said cylinder, and the quantity of oil delivered causes the In the present instance the air passes in at this notch i in small bubbles, and much oftener, and thereby the light is not affected by the running down of the oil from the fountain.

g is a pipe leading from the reservoir c to lthe burner. h is the outer cylinder, and k the inner cylinder of the burner, united at their inner cylinder k is made of sheet metal, and the screw therein is made by bending or com? pressing 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 andv light as possible, in order that it may keep cooler, and not conduct heat down to the coal or similar oil.

Around the tube k is the wick-holder m, carrying the wick n, and this holder m takes the screw-thread in k so as to raise or lower the wick by the rotation thereof. o is a cylinder outside the wick, with a slot taking the projection 1 from m, whereby said wick-holder m is rotated. p is a cylinder outside of h, and connected with the cylinder o.

I have shown the -cylinder p as extending, at the top end, slightly down inside the cylinder h, and notched to take the projections 2 2 for rotating the cylinder o. At the top of this tube p is a1iaring or cup-shaped recep. tacle, 3, that catches any oil that Vmay run down outside. of the wick-tube o, and returns the saine to the lamp and prevents any overiiow.

The cylinder p is connected by arms 5 to the chimney-holder 1', that carries the-chimney s, and a cone, q, between the chi1nney and tube p, directs the air to the base of the flame. Around the base of the cone q are openings at 4, that allow a current of air to pass in between the cone q and chimney s, to aid in keeping these parts cool, and to supply air to the upper part of the flame.

This burner does not become heated to any considerable extent, because the thin sheet metal of which it is composed isv largely exposed to the action of the air, and the cylin- 1. An Argand burner and chimney-holder,`

in combination with the cone q, rprovided with openings 4 to admit air to pass in beinder p and Wick-tube o, as and for the pur? tween the cone and'the glass chimney., subposes set forth.
