IMPROVEMENT IN LAMP-BURNERS.

Specification forming part of Letters Patent No. 40,439, dated October 27, 1863.

To all whom it may concern:

Be it known that I, CHARLEs C. WARWICK, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Lamp-Burning is a full, clear, and exact description of the same, reference being had to the accompa- I nying drawings, making a part of this specication, in which- Figure I is an external view of my invention 1n a closed state, Fig. 2, an external view of the same in an open state with the wick-tube exposed; Fig. 3, a vertical central section of the same in a closed state.

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

This invention relates to animprovedlampburner of that class in which a draft-chimney is used; and it consists in constructing the burner with a tubular slide arranged in such a manner that when the burner is in use the wick-tube by elevating the slide will be entirely inclosed within the burner, and when it is designed to light the wick the slide by being lowered will expose the wick-tube, and thereby admit of the wick being lighted without removing the chimney from the burner, or without elevating or moving in the least the chimney. n

To enable those skilled in the art to fully understand and construct myinvention, Iwill proceed to describe it.

A represents the lower part of the burner, which is simply a cap provided with a screw, a, to screw into a socket on the upper part of the fountain or body of the lamp.

B is the upper part of the burner, which is composed oi a ring or band, b, having a cone or deflector, c, secured upon it. The upper means of vertical bars d, any proper number of the latter being used.

O is the wick-tube, which is secured vertically in the lower part, A, of the burner. This wick-tube is provided with the ordinary serrated wheels, e, which are placed on a rod or shaft, f.

D represents a tubular slide, which is of such diameter that it may be fitted on or around the vertical bars d, and slide up and down thereon. This slide forms the external case of the burner, and it is perforated so as to admit air into the burner whenl elevated, the tube being of such a length as to extend from the lower part, A, to the upper part, B, l

of the burner, and when elevated fully cover or inclose the space between them, as shown in Figs. l and 3.

The tube D is slotted vertically, as shown at g, in order to admit of the rod or shaftf passing through it, and to prevent the latter from offering any obstruction to the rising and falling ofthe former.

At the lower part of the slot g there is a small lateral jog or recess, h, in which the rod or shaft f iits when the tube D is elevated, the latter being thereby retained in a vertical position.

In order to t the rod or shaft f in the jog or recess h, the tube D, w'hen elevated, is slightly turned to the right, and when it is designed to lower said tube it is slightly turned to the left, so that the slot g will be brought in line with the rod or shaftf. When the tube D is lowered,it passes over the socket on the top of the fountain or body of the lamp, and the wicktube C is thereby exposed, so that the wick may be lighted.

By this arrangement it will be seen that in rendering the wick accessible the chimney, which rests on the upper part, B, of the burner, does not require to be removed or interfered with in the least.

In some inventions of this class the upper part of the burner on which the chimney rests requires to be elevated or adjusted in some way in order to expose the wick-tube, and that renders the chimney liable to be broken or casually displaced from the burner-a eontigency which cannot occur in my invention.

I am aware that apertures have been made in the perforated tube or ring D for the introduction to the wick of the lighting-match, said apertures being covered by doors and slides of various forms. I claim nothing of this kind; but,

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, isv Having the perforated ring D, which incloses the wick-tube, made separate and independent ofthe burner and arranged to operate as herein shown and described, so that said ring can be lowered at pleasure, and the wick-tube thus exposed on all its sides, all as set forth.
