LANTERN.

SPECIFICATION forming part of Letters Patent No. 394,025, dated December 4, 1888.

Application tiled November 19, 1887i Serial No. 255,643. (No model.)

.T0 all whom, t may concern.'

Be it known that we, FRANK REGINALD SMITH and ADDISON PINE() SMITH, citizens of the United States, residing` at Houlton, in the county of Aroostook and State of Maine, have invented a new and useful Improvement in Lanterns, ot which the following is a specitlcation.

This invention relates to tubular lanterns in which the globe is mounted in a `globe- 'rame which is attached to the sides ot' the main trame in such manner that the globe and its supporting-frame may be raised when it is desired to expose the burner-cone for trimming, lighting, extinguishing, or otherwise.A

The object ot this invention is the production of a tubular lantern in which the frame that carries the globe when in an elevated position, for' the purpose of giving free access to the burner tor trimming, lighting, extinguishing, or the like, will remain so, and will not drop back until forced down over the burner.

The invention consists in the novel combination and arrangement of the parts, hereinafter fully described, illustrated in the accompanying' drawings, and pointed out in the claim hereto appended.

In the accompanying drawings, forming part of this speciiication, and in which like letters of reference designate corresponding parts, Figure l a perspective view ot' a tubular lantern embodying my improvements in what I deem their best form, the parts being in position for use. Fig. 2 is a similar view of the same with the globe in an elevated position in order to afford access to the burner for trimming', lighting, extinguishing, or otherwise. Fig. 3 is a side elevation ot' the tubular lantern, the globe being removed and the perforated plate tilted, as for the insertion of a new globe.

In the drawings, A designates the reservoircap, B the burner and C C the inclined tubes which conduct air to the burner, and D is the vertical tube, which is a rigid dependent portion of the top of the main trame, all of a construction too well known to require description in detail.

The globe-cap E, as heretofore, is adapted to slide upon the vertical tube D, and is provided upon its under side with a ring-shaped catch, which embraces the upper end of the globe. This ring-shaped catch F is preterably composed ot` a single piece ot wire bent into circular form and having the two ends meeting closely together and securedby soldering or otherwise to the rear ot the globecap E. Intermediately of the ends of this piece ot wire composing the ring-shaped catch is formed a thumb-piece, f, formed by bending up the central portion ot' the wire into two parallel parts, which thumb-piece passes through an opening, e, in the globe-cap E, and enables the ring-shaped catch to be raised, when it is desired to release the top ot the globe to remove it or for the insertion of a globe. Upon the upper side of the globe is provided a piece ot' fiat spring metal, G, which is secured thereto by soldering or similar means. The top of this piece of spring metal G is bent at right angles to its length and forms a locking projection, o2, which, when the globe-cap is down at the bottom of the vertical tube D, engages a shoulder, d, consisting ot' a piece of metal, preferably wire, secured in a suitable manner to the vertical tube D. At the t' ree end ot this piece of spring metal G is iixed a small knob or handle, by which the spring may be made to disengage the shoulder d on the vertical tube to permit the sliding frame to be elevated, the normal position otl the spring being against the vertical tube D. This spring G on the upper side of the globe-ca p E, together with the small shoulder d on the vertical tube, constitutes a locking device, whereby the sliding globeframe may be securely retained in a depressed position.

The globe-trame consists ot' the bottom portion, h2, and the side wires, 71 71, which are mounted in guides 7L 7i. and extend along the inclined sides C C of the main frame to the globe-cap, to which they are secured. Then constructed with reference to economy, durability, and strength, this entire frameismade of a single piece of wire, the ends, as before stated, being ixed to the globe-cap. The bottom portion, h2, of the globe-frame is bent into semicircular form and passes around one side of the burner-cone.

The globe-seat I,which surrounds the burner- IOO cone, is preferably perforated, and is hinged,

y one end of which is attached to the globe-seat,

so that when the sliding globe-frame is in its lowest position the spring K is compressed, the tendency of which is to force one side of the globe-'seat upward, when the top of the globe is released from the globe-frame, thereby causing the globe-seat to turn on its hinge; but when the top of the globe is notreleased from the globe -frame the tendency of the spring K is to force the globe-frame upward and make the said f 1ame slide in the guides h The operation is as follows: When itis desired to insert the globe, the bottom of it is placed upon the perforated globe-seat I, which is (when there is no globe in the lantern and the seat in its lowest position) always in an inclined position. As the globe isbrought to a Vertical position, the ring-shaped catch F is raised by the thumb-piece f and the top of the globe slipped under it. The ring-shaped catch, being then released, descends and fits snugly around the top of the globe and holds it securely in position. The spiral spring K aids in retaining the globe in the globe-frame by exerting a constant pressure upon the globeseat and keeping it in contact with the bottom of the globe. In order to remove the globe from the lantern, it is only necessary to raise the ring-shaped catch by the. thumbpiece and tilt the globe. X/Vhen it is desired to elevate the globe-frame in order to afford free access to the burner B for triniiming, lighting, extinguishing, or other purpose, the spring G, by the knob or handle at its free end, is released from engagement with theV shoulder d of the vertical tube D. The spiral spring K, being then in a depressed condition, instantly acts upon the globe-seat I and forces the sliding globe-frame upward, making it slide in the guides h and assume a position above the burner, as is shown in Fig. 2, and there supports it until forced down again. The spring G, when the globe is forced down upon the burner B, engages the shoulder d of the vertical tube I) and Iirmly locks the globe down and prevents it rising from its depressed position.

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

In a tubular lantern, the combination of a globe-seat, the sliding globe-frame, said seat and frame being hinged together, as shown, and an incased coiled spring bearing against the under side of the globe-seat opposite the point where the said seat is hinged to the sliding globe-frame, whereby the globe-seat is automatically tilted, substantially as described.

In testimony that we claim the foregoing as our own we have hereto affixed our signatures in presence of two witnesses.
