LANTERN yApplication med February 2,1927. serial No. mass?. i y

This invention relatesk to lamps and is more particularly directed to lanterns ofimpioved construction such as marine lanterns lighted by meansr of oil, gas,`or electricity.

An object of the invention is to provide` an improved device ofy the character described having a casing of novel construction form.- ling a rigid structure yfree from soldered joints. i i. if v j o Another objectofgthe invention is. to provide a portable or marine lamp of improved construction and having a novel opening and closure therefor to permit of ready access to the interior'zof' the lamp 'for safe and easy 15 manipulation orl removal of the light providing means, while `at tlie'same time preserving atv itsk maximum kthe uniform lighting quality and usefulness of the lamp. 1 f i', n

Still another object of theinvention is yto provide a lampy ofk the characterl described having a longitudinally split cylindrical globe, a portion of which :serves kas a hinged closure fortheimproved device. y, 4, l

A further object ofk this Ainvention is to provide a lamp of thecharacter :described having a Fresnal type of globe, a wall portion of which is movable to permit of accessA to the interior ofthe lamp, said wall portion beingl then returnable rto its normal position to provide the desired lenseffectywith the light. L a A, still further object oftheinvention is to provide alantern' of the character described of improved construction comprising few and simple parts which are-assembled toform a rugged yet neatappearing structure, which yshall be relatively,cheapv to manufacture, and practical and efficient to a high degree in use.

Other objects of this invention will in part be obvious `and yin part hereinafter pointed out. f f j, j1 f The invention accordingly consists, in the features of construction, combinations of ele,- ments, and arrangement, of parts whichwill be exemplified in theconstruction hereinafter described, and of which thefscope of application will be indicatedin the following claims.

In the accompanying drawing, in which is shown one of the variouspossible illustrative embodiments ofthis invention/,.7 i

lighting devices ,using oil, gas, or electricity,

the lantern disclosed herein asshown is ofL ik adapted particularly for with a Fresnal type of vlens L of novel and improved structure .and futility. The lantern is of very strong and `rugged construction throughout to withstandthe hard use and` wearto. which it maybesubjected. Thus the casing ismade of practically 'rustfresis'tingf sheet metal such asbrass having joints formed ina reliable manner, while the lens or tubular j globe is made of thick glass. Y f

Thecasingfincludes a plurality of coacting i members or parts having joints which preff Saidp'arts f erablyy are united without solder. may` be pressed, spun or cast, kand kjoined together byseams, rivets or screw connectionsy whereby a rigid structure is formed that will y withstandany overheating ofthe lantern inv use without affecting the joints.

Referring more specifically ytothe drawrfiiig,the `lantern includesa cylindrical supy' `porting receptacle lOyhavin'ga closedbotfy l f tomflO, andarranged to receive coaxially therein an oililfount 11 "havinga conveiitional burner B provided with aflame adrjusting screwy y12.r Bayonet connections 13y comprising afslotted member 13a riveted as Y kshown at la to `the receptacle bottoni 10a and pins 13b outwardlylprojecting from the fount c lil-.which engage said member 13u; said bayof net connection has cooperating therewith yan upwardly acting spring l5 secured tothe y of allantern 3 While the yinvention maybe applied'mr bottom of the fount which detachably retain the latter in position. Openings 16 in the wall of said receptacle permit the entrance of air, which is battled by a cylindrical plate 17. An annular ring frame 18 which serves also as a globe supporting means, as will be described hereinafter, is provided at the top of said receptacle. The receptacle 10, plate 17 and frame 18 have parallel contacting flanges 10b, 17a and 18a, respectively, the

ange 1Sa being beaded over as at 13b to form a solderless clamping seam for rigidly joiningV said flanges together. Y

The top portion of the lantern is terr-ninated by a ring handle 27 and includes a hood 19Vhaving air outlets 20 and a -c'oacting f-rusto- Y conical baffle plate; 21 to insure a uniform draft. The hood 19 is Ajoined byY means of a seamedconfnect'ion 23 to angannular member 22; land the baille vplate 21 has an annular bead 24 adjacent the connection 23 forinonnting said `plate in position to form a reliable and air tight joint,pas is Vclearly shown in F ig. 2. The Vmember 22 is formed with a lower rini'lange 22a which engages a ring frame v25, 'the latter rbeing 4similar instructure rand serving the same purpose as Vthe Vconnections herein provided for are solderlessV whereby overheating of vthe casing, lantern top and globe will not Vcause the -seamed joints to open, thus practically eliminating possible fire hazzard. Y

The globeorfle'n's L here is of tubular cylindricalqform and is, split Vlongitudinaflly 'preferably diameterically at 31 and 32, 'aV semi-cylindrical portion 33th-ereovf beingzand forming a closure, which in open position V.permit the*v removal andf replacement ofthe oil fount l and burner to facilitate` lill-ing,

cleaning oradjustment without necessitating 'tipping' ofthe fount, thus'preventing acci-V dental spilling of the oil; The other portion of the globe is stationary being retained in position byupper and lower arcuate Vfra-me members 35 whichy are secured between the ends of the rods 29 yat the; clamp flanges of thecasing and the lantern top portion. The

movable lens portion 33`V forming the closure or door, is mounted upon Va frame including upper and lower horizontally extending arcuate members 36 joinedby connecting rods 37 and screws 38V having their heads` counter- Ysunlr into the members 36. YThe members 4.36

` sectionV adjacent thereto.'

have arcuate slots 39 into which the adjacent rim edges 33a of the lens portion 33 are snugly iitted, the end corners of the glass being undercut at 40. As shown in Figs. 2 and 3, the door frame carrying the lens portion 33 is swingably mounted on one of the rods 29 as Aat 36a on one end of each member 36, whilea lockingdevice such as pivote'd latches Y11 is providedacent the -otherendsof the member `33. n Each latch has notched ends l11 adapted to engage an adjacent end on the fixed portion of the lantern rod 29 and a linger-piece 41b for manipulation of the latch. When the closure is in locked position, the inner edges of the arcuate members 3G abut the rings 18 and 25, as shown i-nFi-g. et, and the closure will Vthen be substantially draft-tight. y i y f To `make a draft-tight joint between the split portions of the lens, the vertically eX- tendingedge faces of the lens portion y33 may be provided with projecting rib extensions n33b adapted to fit into vertically extending grooves 34 formed in the edge faces ofthe lens portion 34 which'normallly abut the 1edge faces of the lens portion 33.

In Fig. 5 is-shown a modified form of drafttight joint for Vthe-lens portions j33 and 34. Here, grooves 134: are lprovided in the lens portion 34. Said grooves yare adapted `to retain a ysuitable resilient .material 100, such as an asbestos packing, the portion of said packing extendingeu'twardly from the edge faces of said lens portion forming gaskets for abutting the edge faces `of the lens por- "f tion 33.

vIt will thusbe seen that there is provided a device in which the several objects of this invention VKare achieved, and which is well adapted to fmeet vthe vconditions of practical Vuse. Y

As various possibleembodiments might be made ofthe above` invention, and as various changes 'might be mad-el in the embodiment above 'set forth, itis to be understood that all matter herein seti forth or shown in the accompanying drawing is to be interpreted as illustrative and Ynot in a limiting sense.
