GEORGE A. BEIDLER, OF MIDDLETOIVN, PENNSYLVANIA.

LANTERN-BURNER.

SPECIFICATION forming part of Letters Patent No. 225,788, dated March 23, 1880, Application filed February 21, 1879.

To all whom it may concern:

Be it known that I, GEORGE A. BEIDLER, of Middletown, in the county of Dauphin, and in the State of Pennsylvania, have invented certain new and useful Improvements in Lantern 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, making a part of this specification.

My invention relates to that class of lanterns in which no chimneys are used; and it consists particularlyin the construction of the burner, whereby is produced the same effect as in the well-known tubular lantern; and my invention also consists in the construction and combination of parts, as will be hereinafter more fully set forth, and pointed out in the claims.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawings, in which Figure I is a central vertical section of a lantern embodying my invention. Figs. 2 and 3 are detailed views of the mutilated cone used therein.

A represents the ordinary oil-reservoir of a lantern, in the top of which the burner is screwed.

The burner consists of the screw or base B,

. wick-tube 0, plate or cup D, air-concentrator E, and mutilated cone (or wings) F.

The screw or base B and wick-tube G are constructed in the same manner as is usual in most burners. To the base is secured the plate or cup D, for supporting the globe G. The bottom of this cup or plate is made convex on its upper side, or slightly conical, and perforated with numerous holes a:, for the passage of air upward to the flame. Air may also be admitted at the sides of the cup or plate D, above the air concentrator, through suitable apertures.

Within the cup or plate D is an annular coneavo-convex plate, E, which fits in or is sprung into the cup or plate; or it may be permanently fastened to the cup or plate, if desired. This annular plate E concentrates centrally the air which comes up through the perforations in the bottom of the cup to and around the wick-tube.

On the wick-tube O is placed a mutilated cone, F, which is made in the form of two wings, as shown. entirely disconnected and removed from the air-concentrator E, and leaving the wick-tube open or uncovered on two sides. The two parts of the cone F are connected by inwardly bent bridges h h, which form guides to fasten the cone on the edges of the wick-tube.

With this construction of burner and a top placed on the upper end of the globe, the light will burn in the lantern without any chimney and without any danger of being put out, no matter how much the lantern may be moved about.

H is the top of the lantern, made in somewhat tubular form, and having a dome-shaped enlargement, I, at its upper end. This dome is perforated on its lower portion to create the necessary draft, and at the same time prevent the wind from blowing down into the flame. Through the upper part or dome of the lantern-top is passed a rod or wire, a, the ends of which are bent downward and their extreme ends fastened to the perforated cup or plate D, thus connecting the top and burner of the lantern.

Around the top H is a movable flangedcollar, J, having the arms of the wire or rod a, passing through the flange, so that the collar can be moved up and down on the rod. This collar J, when pressed down, fits 011 top of the globe, and the spring of the wire it holds it in place thereon, and said collar, fitting around the lower end of the top H, holds said top in proper place. When the collar or rim J is lifted up the top H swings freely on the rod a, and the globe G can be raised for lighting the lantern, or entirely removed, as desired, for cleaning or other purposes.

In some lanterns the mutilated cone may be connected to the air-concentrator, if desired. The top, also, of the lantern may be of different construction, as regards the perforated portion, without departing from the spirit of my invention.

I am awarethat air-guides as well as deeplyslotted cones have been used in burners for lamps and lanterns, and hence I do not claim such, broadly, as my invention.

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

1. The combination of a wick-tube, a cone divided longitudinally in two parts opposite the edges of the wick-tube, and provided with inwardly-bent bridges to form guides for fastening the cone on the wick-tube, and a plate or shell arranged, as shown and described, to concentrate and direct the air to the flame, substantially as set forth.

2. The combination of a wick-tube, a cone divided longitudinally in two parts opposite the edges of the wick-tube, and provided with inwardly-bent bridges to form guides for fastening the cone 011 the wicktube, a plate or shell arranged, as shown and described, to concentrate and direct the air to the flame, and a perforated cup or base plate, substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 21st dayof 25 February, 1879.
