UNITED STATES PATENT OFFICE.

FREDERICK HEIDRIGK, OF PHILADELPHIA, PENNSYLVANIA.

LAMP.

Specification of Letters Patent No. 32,248, dated May 7, 1861.

To all whom it may concern:

Be it known that I, FREDERICK HEIDRIGK, of Philadelphia, in the State of Pennsylvania, have invented certain new and useful Improvements in Coal-Oil Lamps; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, in which Figure (1) represents the body of the wick tube divested of the sheaths and cap. Fig. (2) represents one sheath upon the wick tube. Fig. (3) represents the second sheath over the first coming as will be observed full up to the mouth of the wick tube. Fig. (4;) is a plan View of the top, showing the wick tube, and also the corrugations in the sheaths. .Fig. (5) represents the mode of constructing the sheaths. Fig. (6) represents the whole arrangement put together and ready for use.

The nature of my invention consists in the employment and arrangement of such devices as will be hereinafter fully set forth.

To enable others skilled in the art to make and use my invention I will now proceed to describe its construction.

In Fig. (1) (A) represents the wick tube or burner the lower part of which is provided with perforations, as fully shown, and also as usual the wick pinion (a). The object of the perforations will be more fully appreciated hereafter. It would be well to observe that the collar which surrounds the lower part ofthe wick tube should be provided on its inner side with steps, as it were, for the sheaths to rest upon.

(B) represents the sheath, which should be annular at its lower end, and gradually tapering to an ellipse at its upper end, as shown in Fig. (5), said sheath should be corrugated, which corrugation must extend up around the mouth of the ellipse. I employ two sheaths, though a greater or less number may be used, without very materially changing the effect. My object in thus constructing these sheaths is to feed the flame at the point of combustion with the greatest. quantity of oxygen, as it is well known that just in proportion as the flame is supplied with oxygen, just in that proportion is produced an economical and brilliant light.

Now by constructing my sheaths as already described, and slipping one over the wick tube so that its smaller end will come pretty near the top of the tube, and then putting the other over the first so that its end will come up full, to the end of which tube I supply the flame, with currents of oxygen around its entire body. The sheaths act as chimneys for creating drafts, for as the heated air around" the flame ascends, these sheaths admitting fresh air at their bottom convey it up in small currents, thus constantly supplying the'flame at the pointof combustion with the requisite quantity of oxygen.

Over the mouth of the wick tube I use the cap (F) but do not confine myself to any particular construction of said cap, as I use several of different forms and shapes.

I do not claim broadly the corrugated sheaths,' as they have been known before; but

What I do claim and desire to secure by Letters Patent is-- So arranging said sheaths, that the outside one will come up even with the top of the wick tube, and the top of the 2nd a little below that of the 1st in the manner and
