LANTERN.

SPECIFICATION forming' part of Letters Patent No. 281,797, dated July 24, 1883,

Application filed May 28, 1883. (No modcl.\

To all whom it may concern: Beit known that we, ALLEN J. SAWYER, CLARK WooDBUEY, and EEAs'JUs LANE, all

being citizens of the United States, residing at.

Oldtown, in the county of Penobscot and State of Maine, have invented certain new and useful Improvements in Lanterns and we do herey of our invention, and Fig. 2 a side elevation thereof.

This invention relates to certain new and useful improvements in lanterns, and has for its object to provide a simple and inexpensive means whereby the globe of a lantern may be automatically raised and held above the burner, ready for lighting, when not in use, or to at any time extinguish the flame, said globe being readily closed down upon the burner, when desired to close the lantern, by a gentle pressure of the fingers. Afurther object of our invention is to so construct the upper binding ring or spring, which retains the globe in position,

that the same may be brought up close against the globe-cap, thereby rendering the removal or insertion of a globe easy of accomplishment without danger of its being broken. These objects we attain by the construction substantially as shown in the accompanying drawings, and hereinafter more fully described and claimed.

In the drawings, A represents the usual perforated plate, provided with an annular flange, a, said plate and ange being adapted to receive and support the globe B: i

Suitably secured to and extending out from the sides of the flanged plate A are wings C, forming right .angles b c, and adapted to work on guide-rods D, secured to the tubes or guards of the lantern-frame. These guide rods D have placed thereon spiral springs E, which bear against and are compressed by the right angular portion c of the wings C when the globe and perforated plate are brought down upon and over the burner-cap d.

Secured at one end to and extending up! wardly from the right-angular portion c of the wings are stay-rods F, said rods being se flue, I, of the lantern, an eye, f, connected to said tube or lantern-flue, serving to retain the spring of the catch in its position and form a guide therefor. Vhen the bolt e of thespringcatch H is withdrawn from the perforation in the tube or iiue I, the spiral springs E, bearing against the right-angular portions c of the wings C, automatically force the perforated plate A and globe B up above the burner-cap d, as shown in dotted lines, Fig. 1, and the lantern is thus opened for the purpose of extinguishing the iiame or cleaning the wick, and said lantern may remain open until needed for use.

Vhen it is desired to close the lantern, it is only necessary to press down upon the globecap G Vuntil the bolt c of the spring-catch shoots home, and the globe is thereby locked in its closed position.

Though we have shown the spiral'springs working on guide-rods secured at the lower portion ofthe lantern-frame, the same may be as readily arranged at the upper portion and perform their functions equally well.

` The upper binding ring or spring, K,whicl1,

retains the globe B in its vertical position, is

bent up on either side of said globe a certain distance-say one-half an inca-toward the cap G, then forward and downward ,until it again sets upon the globe, and is provided with an extension, g, passing up through a slot, h, in the globe-cap, terminating in athumb-rest, i, by which said binding ring or spring is lifted from the globe, an extension, 7c, opposite to the one g, being made fast to said globe-cap. When this binding ring or spring is raised up, the bends therein cause its forwardportion to come `close up against the globe-cap, and thereby admit of the easy removal or insertion of a globe.

Having now fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-

l. The means herein described for automati- ICO cally raisingand sustaining a lantern-globe above the burner, which consists of spiral springs placed around suitable guide-rods connected to the lantern-frame and adapted to actuate the usual perforated plate or globe-support, and the stay-rods connecting the rightangular wings of said plate or globe-support with the sliding globe cap, substantially as shown, and for the purpose set forth.

2. The combination, in a lantern, ofa perfo rated annularly-iianged plate or globe-support provided with right-angular wings extending therefrom, with suitable guide-rods secured to the lantern-frame, the' spiral springs placed thereon, the stay-rods connecting the wings of thereon, and provided with a free extension passing up through a slot in the globe-cap, terminating in a thumb-rest, substantially as and for the purpose set forth.

4. The globe-cap of a lantern, adapted to slide upon the central tube or due thereof, provided with a sliding spring-catch locking in a perforation in said tube or iiue, and having` depending therefroin the binding ring or spring for the globe, constructed substantiall5T as shown and described, and suitable stay-rods connecting with the right-angular wings of the perforated plate or globe-support, in co1nbination with the guide-rods to which said wings are inovably secured, and the spiral springs placed thereon to actuate said plate or globe support, as and for the purpose specified.

In testimonyT that we claiin the above we have hereunto subscribed our naines in the presence or" two witnesses.
