To ZALL wHoM 'rr MAY conceals; v l u i Be it known that FRANCIS LEGLBRE, of Watertown, in the county of Jeiieiscmanll'stto of New York, have invented anew and 'useful' Improvement in ,Lanternsgand I do hereby declare that the following is a-full., clear, and exact'description thereof, which will enable others skilled in the art to make and use the same, reifer#4 enccbeing had to the accompanying drawings, forming a part of this specification, in whicht Figure 1 is'a vertical section taken through the line twang. 2.4

My invention has for itsobject to furnish a lantern in which the lamp can be attached to -and detached from the lantern easily, quickly, und with one hand. when necessary, and in which the wick can be raised or lowered a'sr'cquired, without yremoving the lamp from the lantern, or having a button projecting from the side of the lantern forv this purpose. And it consists, first, of peculiarly constructed wire springsl and bail, in'colnbination with eachother and with the lamp and lantern; and second, in the combination ot aratchet-wheel, movable circulan' ruck, and spring for operating th'e same, with cach other and with the lamp 4and burner, as hereinafter 'v more-fully set forth. l

,The lamp A is made slightly cone-shaped, and has a flange, a. projecting from its upper part. This flange l may be l'orme'd by striking up the upper edge cf the sides and the lower odge of th'e cover ofthe lamp, and then uniting those edgesl into a projecting scam or flange, a, or the said flange may be formed and attached in any other convenient. manner. B is the vglobe of the lantern, which is formed and attaohedto the top C and bottom D in the ordinary manner. E is a rod or heavy, wire, running across the top C of they lam'p, and to its projecting ends are pvoted tho'ends of the bail'F. '.lhe bail F is bent .over uponitself so as to form ears,f, for the attachment of the wires G. Thosel enrsf should he formed a short distance above the ends ofthe rod E, so that the wir esG may he raised and lowered vertically as the bailfis raised or lowered. The wires-G' descend along the globe B,`having about the position of and serving as fenders to it. But instead of bein-g. attached to .the bottom D of the lantern as the fenders are, their lower ends enter channels or chambers, H, formed on the sides of `the bottom D of the lantern, as shown in the drawings. Attached to or formed upon the lowor ends of the wires G, are' springs, I, the free ends of which project through openings or slots, d, formed in the sides'of the bottom D of the lantern in the upper part of the chamber H, as seen in dg. 1, and take holdl of the flange a, to hold the lamp. A in its place in the lantern. When the bail F is turned down 'against the' iside of the lautern, the wires Gare forced down further into the chambers H, the springs I being forced entirely within the said chambers by being pushed against the bottomof the slots d. This releases the lamp, and the v lanternl may bercmov'ed therefrom by taking hold of' the small stationary 'bail'.l. '.loreplace the lamp vnothing more y is necessary than to place the lantern upon the lamp by means of the bailJ; then by raising the bail F, the springs I will pass in vthrough thel slots. d, and takel hold of the angc-a of the lam'p A, as before. The upright'guards 'or fenders K, and the horizontal fender L, are arranged and attached in the ordinary manner. To the'top of thelampA, around the base'of the burner, is placed a movable circular rack, M,which revolves freely. Upon the outer edge ot' this rack are formed three or more projections,-N. Teeth or coge gearing into the teeth or coge ot' the circular rack M, are formed around the edge of the button O, npon the projecting end oi' the rod'that carries and operates the toothed wheels that raise and lower the wick, so that the wick may be raised hd lowered by simply turning the rack M in one or the other direction, which raises or. lowers the'wiek es may be desired. This is accomplished without removing the lantern from the lamp by means-of the spring P attached to the-upper part of the bottom D of the lamp, the end of which is turned down,as represented in fig. 1. By revolving the lamp within the lantern or the lantern upon the lamp, this turned down end of the spring P comes in contact with the projections N of the rack M, and revolves itin whatever-direction is required .for raising and lowering the wick.

I claim as now, and desire to secure by Letters Patent- The combination of the bail F, with its eycs'f, the wire G, and spring I, arranged with the slotted chamber H, operating with the lamp A, and its ange a, all constructed and arranged in the manner and for the purpose herein described. v
