Io all whom 'it may concern:

Be it known that LOHARLES T. HAM, of

" the city of Rochester', in the county of Monroe `.of giving access to theburner when the wick `and State of `Nerv York, have invented new .the following is a specitcation.. e This invention relates more particularly to and usefullmprovementsin`Lanterns,ofwhich an improvement in that classof lanterns in which the globe and the perforatcdlplute or `gallery supporting the globejcan be raised, so

as to expose the burner-cone for ther purpose `is required to `be trimmed,or for lighting or` heldin piace.

extinguishing `the flame without `1`equiringthe globe to be removed from the lantern, or to be disconnected from the parts Aby which it is The object of my invention is the construe tioniofasimpledevice whereby theseresultsare attained; and my invention consists, to that` end, of the particular improvements t which I T@will be hereinafter `fully described, and point- `ed out inthe claims.

i In the accompanying' drawings, Figure lis anelevation ot' a :lanternprovided with my `improvements,with theparts arranged in their l. operative position. Fig. 2 is a similar view,

i as` I e taining the oilreservoir with the globe `raised 'so as to expose theburner-cone. Fig. 3 is' a verticalsection,illustrating the spring-catch whereby the globe is se-` cured in `place on the burner-cone. Fig. at is `a horizontal section inline Fig. l.

Like letters of reference indicate4 like parts in the several figures. j v A represents the base ofthe lautern, con- Brepresents the air-chamber, arranged npi on the oilreservoir and surrounding the wicki 'y tube.

. Mair-chamber B.

XG represents A`the burner, restiugupou the D represents the perforated plate or gal- "lery which surrounds the burner-cone and sup- Iports the glass globe E,

Frepresentsthe dished plate or bell arranged overthe upper end of the globe.

G 'represents the air-tube, which rises from the center of the bell F.

H H represent the upper movable portions V1 of the descending air-tubes which connect the portion, the latter, oi' which the horizontal porf tion K forms a part, being rnily secured to the base ofthe lantern, and the upper portion `being iirinly secured to the tube Gand bell F, or the top ot' the lantern, and both portions being so connected together that the lower end' ot' the upper portion can `slide `up and down on the upright portion Kof the lower portion, iu` the manner of a telescopic joint, without disconnecting the -two parts 'of the tubes. I The plate or gallery D is attached to the upper portion, H, ofthe tubes by wires h, so that it takes part in the vertical movement ot' the upper portions of the tubes, thereby causing the plate D and theV globe E, resting thereon, to rise or descend as the upper part oi the lantern is raised or lowered.

L isa spring-catch, which serves to connect the upper movable portion, H, of the side tube with the lower stationary portion thereof when e theglobe isin itslowest position. This'springcatch is composed, as shown in the drawings, ot a hat spring, secured with its upper end to the movable portion H of the tube, and. `provided nearits lower end with aninwardly-pro- `jecting stud or pin, Z, which projects through openings m m', formed, respectively, in the up per movable and the lower stationary parts of 9o the same tube, and which coincide when the globe is in its lowest position. The spring L tends to hold the stud l in engagement with the openings m m', and the movable portion` of the lantern is thereby rmly secured to the lower stationary portion thereof.

'n represents a thumbfpiece, which is attached to the lower end ofthe spring L for withdraw ing the pin Z from the openings m m by press.- ing against `said thumb-piece when it is deroo sired to raise the upper movable portion of the lantern.

o represents a stop, which is attached to the lower stationary portion of the side tube, and

extends upwardly along the lower portion of the proper height the sleeve or strap p will.

come in contact withthe bent portion or enlargement of thestop o, and thereby prevent the further upward movement of the upper movable part of the lantern and its disconnection from the lower part thereof.

The upwardly-converging form of' the side tubes will cause the movable parts of the tubes to slightly bind against the stationary parts thereof when the movable part of the lantern has been raised, whereby the movable part is supported in its elevated position.

By simply releasing the spring-catch L and raising the upper part of the lantern the globe and its supporting-plate are raised above the burner to a sufficient height to permit access to the wick for trimming the same, and for `lighting and extinguishing the ila-me, and by lowering the upper portion of the lantern until the plate supporting the globe seats itself upon the burner the parts are again placed iu their operative position and secured therein by the spring-catch L, which automatically engages when the movable part of the lantern has been lowered to the proper position. The globe can also be readily removed from the lantern, upon releasing the annular spring-catch I, when it is required to be cleaned or for replacing a broken globe.

The construction of the upper part ofthe lantern herein shown and described is of course not essential to the operation ot' my improvement, and may be varied without departing from my invention, so long as the tubes have lamps having a single tube by arranging the stop and catch on the same tube.

I claim as my inventionl. The combination,in a lamp or lantern, of

la base containing the burner, an air-supplytube communicating with the burner andl composed of two parts capable of sliding upon each other, in the manner of a telescopicjoint, the

lower part of said tube being secured to the base of the lantern, a plate or frame adapted to support the lower end ofthe globe and secured to the upper portion of the air'tube, and a catch whereby both portions of the air-supply tube are locked together for securing the parts in their operative position, substantially as set forth.

2. The combination, in a lamp or lantern, of a base provided with a burner, a tube, K K', secured to the base,and provided with an opening, m', a tube, H, capable ot' sliding on the yfixed tube, and provided with an opening, m,

a globe-supporting plate, D, secured to the movable tube H, and a spring catch, L, attached to the movable tube and provided with a stud or pin, l, adapted to engagein the openings m m', substantially as set forth.

3. The combination, in a lamp or lantern,of

' a base provided with a burner, a' tube, K K',

secured to the base,'a tube, H, capable of sliding on the tube K K', a globe-supporting plate, D, secured to the movable tube H,a stopbar, o, secured to the fixed tube, and a strap or sleeve,p, secured to the movable tube, substantially as set forth. l 4. The combination, in a lamp or lantern, of a base provided with a b'urner, a tube, K K', secured to the base, a tube, H, capable of sliding on .the tube KK', and connected at its upper end with a bell, F, a globe-supporting plate, D, secured to the movable tube H, a catch, I, adapted to secure the upper end ofthe globe to the bell F, a spring-catch, L, whereby the two parts ot' the lamp or lantern are secured in their operative position, and a stop device, o, whereby the movement of thev movable part of the lantern is limited, substantially as set forth.
