IMPROVEMENT IN LAMP-BURNERS.

I Specification forming part ofLettcrs Patent No. 37,047, dated December 2, 1862.

T0 all whom t may concern:

Be it known that I, JOHN J. Manor, of Meriden, in the county of New Haven and State of Connecticut, have invented a new and Improved Lamp-Burner, 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 of this specification, in which- Figure l is a vertical central section of my invention, taken in theline x x, Fig. 2.A Fig. 2 is a horizontal section of the same, taken in the line y y, Fig. l. Fig` 3 is a detached side view of the chimney flange or support. Fig. 4, a detached side view of the deljector or coni.

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

The object of this invention is to obtain a lamp-burner of simple construction for burning coal'oil and similar hydrocarbons with a short draft-chimney, so that the lamp may be used as a hand or portable one,capable of being carried from place to place without emitting smoke and an unpleasant odor.

To this end the invention consists in the employment or use of a burner provided with a draft-tube, a detlector or cone, and a chimney flange or supporter, all constructed, combined, and arranged in such a manner that a good internal draft is obtained within the burner, as well as an external draft around the deliector or cone, as hereinafter fully shown and described, and a brilliant and persistent illuminating-flame obtained.

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

A'represents the body of the lamp, which may be constructed in the ordinary or in any proper way; and B represents the burner, which is provided with a screw, a, at its lower end to screw into a cap, b, on the top ot' the lamp, as usual. The burner B is composed of a tube, c, deiiector or cone d, wicktube e, and a daring or bell-shaped liange, f, which encompasses the lower part of the tube c, which is perforated, as shown at g. The tube c is somewhat longer than the main portions of 'the ordinary chimneyburners in order to obtain a better or more powerful internal draft, and in order to have the draft constant or as uniform as possible. The perforations or air-induction openings g are encompassed by the angef, which prevents a direct lateral draft into the burner, as fully shown in Fig. l, and admits of the lamp being carried about without having its dame appreciably affected by the movement or motion of the hand. The deliector or cone d may be of the ordinary form, and connected to the upper end of the tube c by a bayonetcatch or fastening, h. (Shown in Fig. 4.)

C represents an annular dange or chimney supporter, which is formed with a horizontal shoulder, i', on which the draft-chimney D rests, and may be secured in any proper inanner. The lower part of the liange or chimney supporteris bent inward, as shown atj, so as to lit snugly around the tube c, while the part lc of the tiange, immediately abovej, projects outward from the tube c sufciently to allow a draftpassage into the chimney, the part It being perforated to admit the air, as shown at Z. The flange C is secured to the tube c by a catch or fastening, m, aud at a point just below the base ofthe cone, as shown clearly in Fig. 1. From the above description it will be seen that the flame of the lamp will be supplied with au internal and external draft of air, and owing to the strength of the internal draft, caused by the tube c, a comparatively short chimney may be used; and in case a very brilliant flame is not required, nor a large one-as, for instance, where a night-lamp is required for a bed-room-the chimney may be dispensed with entirely, the liange C being detached from the burner.

This burner has been practically tested and answers admirably well. It may be carried about from place to place like an ordinary fluid or whale-oil lamp without emitting any smoke or odor. It may be constructed at a small cost, and may be trimmed and kept in proper burning order wit-h equally as great facility as the ordinary burners in use.

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

The burner B, having its tube c perforated at its lower end and encompassed by the guard or flange f, in combination with the perforated annular iiange or chimney supporter C, applied to the tube c below the delliector or cone d, all arranged as and for the purpose herein set forth.
