LANTERN.

SPECIFICATION forming part of Letters Patent No. 349,618, dated September 21, 1886,

Application filed March 19, 1886.

zen of the United States, residing at Chicago,

in the county of Cook and State of Illinois,

, have invented certain new and useful Improvements in Lanterns, of which the following is a specification, reference being bad therein to the accompanyingdrawings.

This invention relates to that class of lanterns in which the air is supplied to the flame through tubes which communicate with an airchamber below the burner and extend upwardly on the outside of the globe to or above the level at which the products of combustion or the heated air escape from the lantern.

The object of this invention is the construction of a simple and compact lantern of good appearance, particularly adapted for use by firedepartments, and in connection with fire-dcpartment apparatus, in which the flame is not extinguished when the lantern is exposed to the wind, or is violently agitated or is struck by water from a hose.

My invention consists in the peculiar c011- struction of the lantern, as will be hereinafter fully set forth in connection with the drawings, in which Figure 1 represents one half of the lanternin elevation and one half in section. Fig. 2 is a top view of the same lantern, constructed in accordance with my invention. Fig. 8 is a bottom view of the casting forming the upper end Fig. 4 is a top view ot'the oil-cup,showing in horizontal section the air-chamber resting thereon and a portion of the air-feeding tubes. respectively, in side view and topview the disk through which the air passes before entering the air-feeding tubes/ Figs. 7 and 8 represent, respectively, in side view and top view the combined disk and cap used to assist in protecting the air-passages in the top of the lantern. Figs. 9 and 10 represent, respectively, in side and top view the lower disk or holder for the upper end of the glass globe.

In said drawings, a represents the oil-cup carrying the wicktube b and burnercone c, and upon the shoulder of said cone rests the perforated plate q, supporting the lower end Figs. 5 and 6 represent,

small quantity of air if the supply through the tubes should be insufficient. The tubes 9 extend upward on the outside of the globe to a point above the 16 e1 at which the products of combustion are discharged, and enter the ends of a hollow casting, h, to thecentral portion of which is attached the upper hemispherical cap, 1', having its lower edge flanged out and forming the disk 2', to prevent the entrance of falling water into the lantern. A short distauce below the combined cap and disk i is secured another nearly similar combined cap and disk, Z. The fastenings between the two consist of four small bolts, 02, passing through the disk 2' Z at substantially diametrically 0pposite points. A sleeve, of, is placed upon each of the bolts a, to keep, the disks at proper dis tances apart to form an'annular passage for the admission of air into the bottom entrance to the casting h, andinto said annular passage there is 'placeda perforated disk, k, to moderate and equalize the ascending current of air.

This disk It has its inner flange riveted to the convex surface of the cap Z, and the latter has a series of small pertoiations,l,to permit a portion of the heated gases from the interior of the globe to ascend under the upper cap, 2'. The upper end of the glass globe is retained in a proper central position by means of a ring, m, having flanged base or disk m", through which passes as guides the lower portion of the bolts n. v

To raise and lower the ring in it has in its upper portion a diametrical bail or transverse bar, m, centrally perforated and screw-tapped to receive the vertical screw -0. The upper The bottom of the casting h has a large opening, h, to permit the free passage of the screw, and the cap Z has also a large central opening, 2*, for the same purpose. Two or more wires, are made to encircle the tubes {1 opposite the middle portion of the globe d, to protect the latter against concussion. Projecting from the top of the casting hare perforated lugs h to receive the looped ends of the wire handle 8.

The oil-cup a is of such size as to contain a supply of oil to burn about thirty hours.

The lantern is lighted by inserting toward the wick a lighted match in the largest hole made in the perforated plate q,- but when the wick is to be trimmed or the globe cleaned, by slackening up the screw 0, which elevates the ring m from on top of the globe, and after the wick has been trimmed and the parts cleaned the globeis then replaced and the ringm forced down upon it by the central screw.

The heated gases and products of combustion ascending in the globe pass out mostly be tween the disks Z and m; but a small portion also passes upward through the perforations l in the disk Z and through the perforation in the disk k, whereby they become mixed with the fresh air entering between the disks i and Z, and enter the curved passages in the casting h,leading to thetubesg, and downward through them to the air nlyaniber e surrounding the wick-tube.

By the arrangement of the caps H m and their horizontal flanges or disks 5 MM, the upper end of the globe is well protected against a stream of water that may issue from. a hose, so that the lantern cannot be extinguished thereby.

Having now fully described my invention, I claim- 1. A lantern provided with side air-tubes,

connected with an air-chamber around the burner, and with a tubular casting and an up per cap having its lower edge'ilanged outward ly, and under said cap two other caps having their lower edge flanged outwardly, and a screw passing through the caps whereby the lower cap is vertically adjustable, in combina tion with a glass globe entering and fitting within the lower cap, whereby the admission of water projected against said globe is prevented, substantially as and for the purpose described.

2. In combination with the oi l-cup, burner, glass globe, and the side air-tubes of a lantern, the casting receiving their upper ends and the hemispherical cap secured to said casting and provided with an outwardly-projecting disk at its lower edge, the combined cap and disk Z, and bolts 01,, uniting the disks of both caps, substantially as and for the purpose described.

3. In combination with the oil-cup, burner, glass globe, and the side air-tubes of a lantern, the casting receiving their upper ends and the two caps with their pendent guide-bolts, the globe receiving disk having perforation for the passage of said guide-bolt, substantially as and for the purpose described.

4. The combination of the oil-cup, burner, glass globe, and the side air-tubes of alantern, the casting receiving their upper ends, the two caps retained apart by bolts passing through their outward]y-prqjcctiug disks, and the perforated disk k between the caps, substantially as and for the purpose described.

In testimony whereof I affix my signature in presence of two witnesses.
