PERKINS LAMP Filed Dec. 10, 1927 INVENTOR Lou/5 [OH 4R0 Paar/m: BY g ATTORN E Y Patented Oct. 29, 1929 UNITED STATES PATENT OFFICER LOUIS EDWARD PERKINS, OF RI(.'1I-I1IIOND HILL, NEW YORK, ASSIGNOR TO PERKINS MARINE LAMP CORPORATION, OF BROOKLYN, NEW YORK, A CORPORATION OF NEW YORK LAMP

Application filed De'cem ber 10,1927. Serial No. 239,095. v

This invention relates to lamps, and is more particularly directed to improved lan-- tern globes and mountings therefor.

An object of thisinvention'is to provide a lantern globe for a portable or'marine lamp, said globe being provided with novel closure means permittmg ready access to the interior ofthe lamp for safe and easy manipulation or removal of the lightprovidingv means, while at thesame time preserving at its maximum the uniform lighting quality andusefulness of the lamp. I

A further object of the invention is to provide a lantern having aglobe of the character set forth, and improved means for.

are not claimed herein. p I Other objects ofjthis invention will in part be obvious and in part hereinafter pointed out. w

The invention accordinglyconsi'stsin the features of construction, combinations of elements, and arrangement of parts which'will' be exemplified in the construction hereinafter described, and of which thescope ofapplicationwill be indicated in the following claims.

In the accompanying drawing, in which is shown one of the various possible illustrative embodiments of this invention,

Fig. 1 is a view in elevation of a lantern embodying the invention, parts being broken away to show the method of mounting the globe and lighting unit therein;

Fig. 2 is a view in section taken on line 2-2 of Fig. 1, parts being broken away to show the mounting of the globe sections in their respective frames.

Fig. 3 is. a fragmentary cross-sectional view showing the, closure member partly swung to open position, and with portions broken away to show the method of mounting a globe section. i

Figs. 4 and 5 are elevational views of the: I

fixed and movable portions of the globe, taken in the direction of the arrows 4 -4 and 5-5 of Fig. 6, respectively, with part of the frame for mounting such] portions attached, "and further showing theabutting edgeconstruo tionof the globe portions; and

Fig. 6is a'topplan view showing an end of an assembled globe.

Whilethe invention maybe applied to lighting devices using oil, gas,,or electricity, thelanterndisclosed herein, as shown, is of;

the oil burning type, adapted particularly;

for marine service. y 1 Referring in detail to the drawing,the lantern embodying the invention there shown comprises a casing H, and a tubular globe I formed preferably with a Fresnel type lens. L formed of thick glass. Said casing in-; cludesa cylindrical supporting receptacle 10 arranged toreceive coaxially therein an oil' fount 11 having a conventional burner B. Openings 12 in the wall of said receptacle permit theentrance of air,while openings 13 in the hood 14 of the casing provide an outlet for said air. The top portion of hood 14 of the lantern-and said receptacle 10 are firmly inter-II connected by spacing rods 16 which have their ends secured by means of screws 19 to clamp flanges 17 and 18 of said hood andreceptacle respectively. A ring handle 15 is convenient,

1y positioned at the top of the lantern.

The globe or lens L is of tubular .cylindrical form and comprises the two semi-cylin drical portions 22 and 23, the edges of which abut as at 20 and 21 to present the torm of a.

cylindrical ;lens. Portion 23 is fixed with;

respect to casing H, while portion 22 provides a movable closure for the casing which may be swung to an open position to allow ready access to the interior of the lamp whenever necessary, as for example, to permit removal and replacement of the oil fount andburner, thus facilitating filling, cleaning or adjustment without the inconvenience of tipping" the fount and avoiding accidental spilling of oil.

surface-along its-circular edge, against rings 25 which extend. ClOWDIIItO'thQ'glQbSfIQHI- the hood 14 and up from receptacle 10 of the lantern. Preferably the globe portion is undercut along its flat, curved-shaped edges to provide a semi-annular projection.

26, at the upper and lower ends of the portion 23, the inner edges o'f th'e ar'cuate fraane rnenibers 2 1 being received against this ring and fitting tightly against the faces 23 and 26 presented by' the undercut construction." In

this manner, the projections 26 are rigidly retained between" the hame '--niembers 24 anel the rings 25 I The -movable= lens portion 22 forming the closure or door'is' mounted upon a frame-Fin cluding upper and lower horizon-tally extending arc-.uat-e. members 27, joinedby connecting rods 2 8,"screws 28"received in rods- 28 and havingtheir heads countersunk linto members 27 providing-means the relation of these several parts. The frame F is thus adapted .for snug and" siidablie fit between the clamp flanges 17' and J 18750 1 that by making'this frame of proper height to contact the inner edges .of' 'tlie-inembers 27 against the rin gs'25, draft ti ght'; apparatus willbe presented.

The closure portion22 of tlie globeiis undercut along" its; flat, 'curved shape'dedges 2 2 to provide the arcuate projection 30, while; the frame members 27 are formed wlth curved recess'slots 31, bounded at the"v ends thereof bysides'32 the projections 30ybeing cut away at 32 "atsaidsideto provide space therefor.

It will" thus be seen that the closure portion 22.offthe globe'is reliably secured in the movable frame of'theflantern", andjn asimplified" andiimproived manner. As shown n Figs. 2"v

andS, the door frame F carrying globe portion 22 is provided'witha projection or'pivot portio1r27' "received on-oneofftlie rods 16, as atIG I p g The projection 27 is'so positioned on frame me'mber27 as toallow proper rotation ofthe door: fi'a me' with respect to the fixe'd portion' Each of! said fixed'members 24 is pro:-

vide'd with a cut: out '24:? for properl'yreceivmgpro ection 27? to allow pivotal movement ofithe severaipart's.

As can be seen inrig. 1', the'projections 3O of the movable globe portion are of less" heightithadprojeetions 26'of the stationary globe" portion, thus ensuring the desired cliearancejat the clamp flanges 1'7land 18i When the swingab'le closure isin locked position, as shown in Fig. 2', it is substantially draft-tight at the upper and lower edges of the movable globe portion 22. Looking devices such as pivoted latches 33 are provided at the end of members 27 removed from pivot rod 16 for engaging related parts on the frame members 24.

To make a draft-tight joint between the split portions of the globe, the vertically extending edges of the fiXed-andmovable globe portions are formedwith stepped joints or mating rabbets 23 and 22, respectively.

Preferably the rabbets 23 of the stationary globe portion are formed to be received with in thesrabbets 22 of the movable globe portion. Thus said rabbets constitute a reliable means 'foraiding'in the=alinement and coaction of the globe portions, providing extended surfacecontacttomake'the globedrafttight, andzincreasing resistance toany draft leak'atthis point;

Itwillithus beseen that there; is provided a device in which' the'several objects of this invention are achieved, and which is well adapted to' meet the; conditions of practical use. i i

As various'possible embodiments might be made of the abovesinv'ention, a nd'as various cliangesmighttbemade in the embodiment above set-foitlhitzis tobez'understood that all matter herein 1 set: forth or shown in: the accompanyingrlrawingris to be interpreted as illustrative and notzin a limiting sense.
