LANTERN.

SPECIFICATION forming part of Letters Patent No. 410,943, dated September 10, 1889.

Application filediluly 2, 1888- Serial No. 278,745. (No model.)

To all whom it may concern.-

Be it known that we, WILLIAM C. STEWART and JAMES A. BLANKLEY, citizens of the United States, residing at Bellaire, in the county of Belmont and State of Ohio, have invented certain new and useful Improvements in Lanterns; and we do hereby declare the following to be a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to various new and useful improvements in lanterns, particularly to means for raising and retaining in araised position the globe and globe-supports of such lanterns, and by the use of our invention the resulting article is simpler and more economi- The globe and globe-supports when lowered are firmly and automatically locked, and when raised are also looked. The means for raising such globe and globe-supports are entirely isolated from the burners, and consequently are always cool. The air-supply tubes are not impeded in any way. The globe and globe-supports when raised are above and to one side of the burner, so as to permit the perfect access to the same, and the globe may be quickly removed from the globe-supports.

Our invention consists in a peculiarly-constructed lever pivoted to the top of the oilchamber and attached to the bottom of the supporting-disk by a novel hinge, whereby when said lever is depressed the globe and globe-supports are first elevated nearly vertically until the top of the burner-cones is cleared, and then both upwardly. and outwardly in the path of an arc of a circle, as well as in other details of construction, all of which will be more fully hereinafter described and claimed, and which are illustrated in the accompanyingdrawings,wherein similar parts are indicated by identical letters and figures of reference in each View, and in which- Figure 1 is a side elevation of the lantern with the globe in its normal position; Fig. 2, a front elevation showing the globe as being raised; Fig. 3, an elevation of the lever and a portion of the globe-supporting disk, and Fig. 4 a perspective view of the lever.

The oil-chamber A, side tubes B B, bail or handle 0, central tube D, canopy or bell E,

and burner-cone F, with wick-raising wheel G, are all old and well-known elements in tubular lanterns, and to which we wish to make no claim. Extending downwardly from the canopy or bell E, and running parallel with the side tubes B B, are wires a a, curving inwardly at b and secured to the perforated base or disk H in any suitable manner, preferably by soldering. A globe I is adapted to rest on this base or disk H, and is retained in position thereon by a grip c, of a well-known construction, bearing against the upper bead of the globe and secured to the under side of the canopy or bell, and provided with a fin gerpiece (1, by means of which the grip 0' may be elevated and the globe removed.

The opening in the canopy or bell through which the central tube D passes is rather larger than usual, for the purpose hereinafter explained, and in order that the air from the interior of the globe cannot escape through this opening the lower portion of the said central tube D is flanged outwardly all around, as at e, so as to effectively cover this opening.

At the point f on the top of the oil-chamber is pivoted the lever J, made, preferably, of a single piece of wire as follows: Beginning at the coupling 1, which is composed of a single piece of spring metal bent on itself to form a sheath and inclosing the two ends of the wire, the wire extends horizontally outward to the points 2 2, then at right angles for a short distance to the points 3 3, then with a long slightlyoutward curve passing on each side of the burner-cone and extending downward to the points 4 4 at the top of the oil-chamber, then horizontally inward, passing through the hinge K, made of a single piece of sheet metal, to the central opening 9 in said hinge, at which point the wires come together, then at right angles to the points 5 5, then upwardly,forming the hook L, and finally in the path of a circle, forming the loop or finger-piece M.

The form of lever just described is capable of many modifications, the only essentials in the construction being the general outline or loop N of the lever before the hinge K is reached, and an arm N and inclined hook L on the other side of the same. At the coup ling 1 this lever is held in proper relation to the under side of the base or disk H by means of a peculiarly-constructed hinge, which is composed of a piece of sheet metal 0, passing over the coupling 1, so that said coupling has a certain amount of movement back and forth in said hinge.

lVhen it is desired to elevate the globe for the purpose of gaining access to the burner or for cleaning, the loop or finger-piece M is depressed and disengages the hook L from the inclined flange h of the base or disk II. The arm 7t, bearing in the hinge K, will also be depressed and will elevate the large loop N, and thus move the disk or base II. The first movement of this loop N tends to raise the globe nearly vertically above the burner by reason of the coupling 1 moving laterally in the hinge O. \Vhen the limit of this lateral movement on the part of the coupling 1 is reached, by reason of the coupling coming in contact with the rear of the hinge O, the globe in following the movement of the loop N will be further elevated and swing outwardly in the path of a circle. It will be seen that byswinging the globe upwardly and outwardly, as just described, the canopy or bell E is turned at an angle to the central tube, and for this purpose the opening in the same through which central tube D extends is made larger than usual, as was before mentioned herein. The globe, when elevated, is locked and held in such position,because the upper part of the canopy or bell comes into contact with and bears against the upper or horizontal portions P P of the side tubes B ]3,which tends to force the loop N out of the perpendicular; but this pressure is resisted by the arm h coming into contact with the top of the oil-chamber. To bring the globe back into its normal position, the arm h is raised, the globe swings back and down over the burner, and the hook L passes over the flange h and locks the globe in position.

Such a lantern as just described can be readily made and operated, and there is no danger Whatever of the globe becoming detached or the light being extinguished by the globe in being depressed, for the reason that the globe partakes of the movements as described.

lve make no broad claim to a lever pivoted at or near the base and constructed to raise the globe and move it laterally away from the burner.

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

1. In a tubular lantern, the combination, with the base, side tubes, central tube, globe, and globe-supporting disk, of a lever pivoted to said base and provided with loop N, surrounding the burner-cones and hinged to said globe-supporting disk, and with a lockinghook L, engaging with the flange of said globesupporting disk, substantially as described, and for the purposes mentioned.

2. In a tubular lantern, the combination, with the base, side tubes, central tube, globe, and globe-supporting disk provided with a hinge O thereon, of a lever pivoted to said base and secured to said disk by means of said hinge and provided with a locking-hook L, for the purpose mentioned, substantially as set forth.

As an improvement in lanterns, a globe connected to the central tube at its upper end, a base, a supporting-disk for said globe, and a lever pivoted on the base and connected to said disk, and having an integral latch-arm engaging with said disk, substantially as set forth.

In testimony whereof we allix our signatures in presence of two witnesses.
