IMPROVEMENT IN LAMP-BURNERS.

Specification forming part of Letters Patent No. 76,979, dated April 21, 1868.

T0 all whom t may concern.'

Be it known that I, G. A. BELDLER, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Lamp-Burners; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon.

The nature of my invention consists in providing a lamp-burner, adapted to screw on any ordinary kerosenellainp, that will burn without a chimney, producing a clear, white light, (though, if desired, it is so arranged and provided that a chimney may also be used in connection.) It consists of a conical deflector, and within it a rarefying-conductor, in such a way made and attached as that the air which passes up within the conical detlector is not divided or separated, the outer portion from the inner, as is the case where there are two complete and unslitted cones, but is left free to mingle throughout its passage up within the conical detlector till near the top of the same, thus securing the equality of the current of air to the flame inside as well as out-A side ofthe rareiying-conductor.

' Figure l is a vertical section of the conical deilector A, inside of which is shown the rarefying-conductor B, and at the bottom of both of which is seen, at C, the perforated plate or wire-gauze diaphragm. Fig. 2 is a bottom view of the base of the conical deiiector A, and within it the rarefying-conductor B, also the arms c a a, holding all to- A gether. Fig. 3 is the chimney-holder D, with double springs H and chimney E.

To enable others skilled in the art to make and use my invention, I will proceed to describe it as follows, viz:

I construct the conical deflector A similar to, though somewhat larger than, the usual way. I then make the rarefying-conductor B at its apex of a conical form, while from about threefourths of an inch below its apex to its circumference or base it is slit all around into narrow strips. These strips are then twisted at their .upper end one -fourth of a revolution around, so that they win stand with their n1 ner edges toward the center, and their outer edges toward the circumference, and about one-fourth of an inch apart, as is shown in Fig. 2. I select three of said strips, e e e, equally distant from each other, which I do not twist, the lower ends of which are soldered or fastened to the inner surface or bottom of the conical deflector A in such a way as'to hold the rarefying-conductor B in its place within the conical deiiector A, and leaving an annular space between them of about onefourth of an'inch. I thenv connect the conical detlector A to the screw ol' the wick-tube F by means of the arms a a a or perforated plate C, and thus the conical detlector A and rarefying-conductor B are attached to the wick-tube,

the latter being attached in the usual way to v the screw F. The chimney-holder D, Fig. 3, is made to fit neatly on the conical dellector A at c c, Fig'. l. Attached to this holder are three double springs, H, as seen in Fig. 3.

This holder D is perforated, and, with the three double springs H, is for the purpose of holding the glass chimney, as shown in Fig. 3. lhe whole may or may not be used on the burner, as desired.

Having thus fully described my invention,
