PATENT OFFICE,

OF NEW'YORK, N. 'Y.

Specification forming part of Letters Patent No. 37,983, dated March 24, 1863.

To all whom it may concern:

Be it known that I, JOHN WILLIAM ScHREr- BER, of the city, county and State of New York, have invented a new and Improved Burner for Burning Coal-Oil Without a Chimney and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part ot'this speciiication, in which- Figure l is a side view of my invention applied to a lamp; Fig. 2, an edge view of the same; Fig. 3, a detached plan or top view of th same.

Similar letters of reference indicate corresronding parts in the several figures.

This invention consists in having the upper end of the wick-tube, which is of the ordinary flat form, rounded at its upper end and havin g the wick-tube inclosed within a perforated jacket, the upper end of which is provided with a slot or opening, contracted at its center and enlarged at its ends, as hereinafter fully shown and described, whereby a good illuminating-flame is obtained without the aid ofa chimney.

To enable those skilled in the art to fully understand and construct Ill) invention, I will proceed to describe it.

A represents the body or fountain of a lamp having asocket, B, on itsupper end,into which the burner U is screwed. This burner is cornposed of three parts, a b c. The lower part, a, is screwed into the socket B and it is perfo rated with holes d, and is of flaring form, the upper part being provided with a vertical rim or flange, 6, within which the lower edge of the upper part, b, of the burner is fitted. The part c of the burner is the wick-tube, which is of the ordinary flat form, and is permanently secured in the part a. The upper end, f, of the wick-tube is rounded or made of semicircular form, as shown by the dotted line in Fig. l. The upper part, b, of the burner is of cylindrical form at its lower end, and of such diameter that it may fit snugly within the rim or flange e, as shown clearly in Fig. 1. This part b of the burner is also perforated with holes, 9, and it is gradually flattened from its lower to its upper end, as shown in Fig. 2. In the upper end of b there is a slot or opening, it, which extends entirely across b and is considerably wider at its ends than at its center. (See Fig. 3.) The slot or opening it is a short distance above the top of the wick-tube, and the latter is directly underneath or in line with the narrow central portion of the slot or opening; It. By having the upper end of the wick-tube c of rounded. or semicircular form a greater surface of wick is obtained than if the wick-tube were straight or horizontal at its upper end. This shape of the upper end of the wick-tube in connection with the peculiarshaped slot or opening it. in the upper end of the part b of the burner, causes the flame to be spread out so that a large surface of the latter will be exposed to the air, while the top of the part b above the wick-tube 0 serves as a gas-chamber, to which air is admitted through the perforations 9, sufficient to cause an imperfect combustion only, the vapor being spread out just above the wick and burning with a good illuminating-flame above the part b.

1 do not claim a wick tube with a semicirculartop or rounded atits upper end, for they have been previously used; neither do 1 claim, broadly, a perforated jacket, irrespective of the form of the slot or opening it, in its top; but,

Having thus described my invention, what I do claim as new, and desire to secure by Letters Patent, is

The combination of the roundedtop wicktube 0 and the perforated jacket I), when the latter is provided with a slot or opening, it, in its top, having its central part narrower than at its ends, as herein set forth.
