OF BA NGOR, MA l LANTERN.

SPECIFICATION forming part of Letters Patent No. 389,083, dated September a, 1888.

Application filed March 12, 1857.

To all whom it may concern.-

Be it known that I, HARVEY L. JEWELL, a citizen of the United States, residing at Baugor, in the county of Penobscot and State of Maine, haveinvented newand useful Improvements in Lanterns; and I do hereby declare that the followingisafull, clear, and exact descrip' tion of the invention, which will enable others skilled in the artto which it appertains to make and use the same.

My invention relates to improvements in that class of lanterns in which the globe is held in position by a sliding frame, wherebyit can be raised from the burner-cone for exposing the latter in order to facilitate the operation of lighting and trimming the wick and extinguishing the flame.

My improvements consist of certain details of construction hereinafter described, shown in the drawings, and pointed out in the claims.

In the accompanying drawings, consisting of two sheets, Figure l is an elevation of a lantern provided with my improvements, the globe-framebeinglowered. Fig. 2 isasimilar view with the globe-supporting frame raised. Fig. 3 is an elevation of the upper part of the lantern at right angles to Fig. 1, showing also in dotted lines the globe in the position in which it engages the free ends of the springarms to press them apart. Fig. i is an elevation of a lantern, showing a different application of my lifting devices. Fig. 5 is a front elevation of the lower partof the globe-supporting frame and supporting-disk, showing the disk partly tilted or inclined, as it is when applying and removing the globe from the frame. Fig. 6 is a plan view showing the spring-arms separated for the insertion of the globe. Fig. 7 is a plan view of the devices constituting the catch which holds the globe frame depressed.

In the drawings, A represents the base of the lantern; B B, the side tubes; 0, the centraldraft tube; and D, the bell or cap of the globesnpportingframe, having avertical movement on the tube 0.

E represents the burner-cone, F the tilting globe supporting disk, and G the globe.

H is the bilateral elastic double-wire globe holder and guide attached to the bell D, said holder and guide being composed of the wires Serinl No. liltLFOil. (No model.)

ii, one passing above, the other below, the rib on the globe, as shown in the drawings. thus effectually preventing any displacement ofthe globe in a vertical direction. Said holder being constructed in two parts (right and left sides) secured at the rear 10 the globe-supporting frame, embracing the sides oi the globe, and being horizontally elastic and movable, it readily admits the globe between its free ends, while the wires above and below the rib guide it into its proper position.

I represents the shouldered spring stop holding the globesupporti ng frame in its lower position.

J is the vertical depressing rod and guard.

k 7c represent the side wires or rods of the globe-supporting l'ruine attached to the bell D and turned in at their ends to supportthe disk F pivotally. and being free to slidein the guides or loops Z Z, secured to the side tubes, B B. m m are coiled springs, preferably surrounding the rods or wires 7;, between theloop land either the lower or upper ends of said wires.

n is a ihimble attached to the bell D, to which is seen red the springstop I and the rod J, said thimble having a vertical movement on the tube 0. 0 is a disk attached to the upper end of the tube 0, having openings through which the stop I and the rod J slide.

My device for automatically raising the globe-supporting frame accomplishes the same resultby the use of apull or push spiral spring, preferably coiled about the side wires or rods, k. WVhen used as a pullspring, the ends are respectively attached to the loops Z and the lower part of the rods is, as shown in Fig. 1. \Vhen used as a push-spring, the ends bear respeotively upon the loops land the small disks attached to the upper part of the rods 7;, as shown in Fig. 4.

\Vhen the globe-supporting frame is to be raised for the purpose of lighting or trimming the wick, a slight inward pressure upon the upper part of the spring-stop Idisengages the shoulder 19 from the under side of the disk 0, allowing said stop to slide in a vertical direction through the slot in the disk 0, thereby allowing the globe-supporting frame to be moved vertically by the action of the springs, thus obviating the necessity of raising the globe frame or of holding it in its upper position while in the act of lighting the lantern.

The operation of my invention is as follows, supposing the globe to be down, as in Fig. 1: It being desired to raise the same, the forefinger is placed upon the flat bearing at the upper end of the rod J, and the stop Iis pressed inward by the thumb until its shoulder 19 is disengaged from the disk 0. The globe holder and globe will immediately spring upward, such movement being governed by the pressure of the finger, so that the globe may not be broken or thrown out of its holder. The wick having been trim med, lighted,or extinguished, as may be the case, the pressure is applied to the fiat top of the rod J, and the holder and globe forced downward until the stop I springs out,with its shoulder 19 under the disk 0, when the hand may be removed and the parts will remain securely held in the position shown in Fig. 1. To remove the globe, the two parts of the wire frame H are pressed apart and the upper end of the globe passed out between their ends. As the globe is thus swung out of J a vertical line, it continues to rest upon the disk F,which accordingly turns upon the horizontal pivots formed by the ends of wires 70 to accommodate the position of the globe. When the globe has cleared the frame H, itis removed from said disk. In inserting the globe it is first placed in an inclined position upon the disk F, and then tilted upward till the head of the globe enters between the ends of the 'frame H, and having first pressed said ends outward, is finally clasped and secured by the frame as its parts spring back into place. The particular construction of the globe supporting frame herein described and shown is not material so far as the catch is concerned, and my device for automatically. holding said frame may be applied to frames of various forms of construction with the same effect.

What I claim, and what I desire to secure by Letters Patent, is-

1. In a lantern, the combination, with the globe supporting frame, of the double horizontally-operating spring-arms secured there to and having portions for engaging the globe both above and below its bead, said springarms being free at and having an opening between their forward ends, and the tilting plate F, for supporting the lower end of the globe and adapted to oscillate therewith'as the globe is turned from an inclined to a vertical position, thereby insuring that the proper part of the globe shall meet and enter between the said arms, substantially as set forth.

2. In a lantern, the combination, with the globe-holding frame and as a means for se curely holding the upper end of the globe, of

the double horizontally-operating spring-arms ii, secured at the rear to the globe-holding frame, free and separable at and having an opening between their forward ends, andhaving portions for engaging the head of the globe on both its upper and lower sides, substantially as set forth.

3. In a lantern, the combination, with the main frame having the central tube, 0, of the globeholding frame sliding on said tube and having the side rods, k, guides ll, engaging said rods, springs m m for pressing the globeframe upward, the push-rod J, carried by the globe-frame, the spring-stop I, also carried by the globe-frame and having the shoulder 12, and the disk 0, mounted on the tube 0, having a guidingopening for said push-rod, a slot for and inclosing the said spring-stop and adapted to be engaged by the shoulder of the latter, substantially as described.

HARVEY L. JEWELL.
