JOHN H. IRWIN, OF CHICAGO, ILLlNOIS.
IMPROVEMENT IN LANTERNS.
Specification forming part ofI Letters Patent No. 65,229, dated May QB, 1867.
To all-'whom it may concern: y
B e it known that I, J onuv H. IRWIN, of Ohicago, inthe county of Cook and State of Illinois, have invented a new and useful Improvementin Lanterns; and'I do hereby declare and make known that the following is a full, clear,
and exact description of` the same, reference being had to the accompanying drawings, and the letters and figures marked thereon, which form part of this specification.
My said invention relates to that class of lanterns. in .which two globes are used, onewithin the'other; and it consists inse construct ing the lantern that vunder no circumstances can a'downward k"d ra'ftn occur within the interior globeyanrl alsoin so'constructingsaid lantern that'the said interior globe may bere-,
moved from the lantern and the exterior globe thereof eithcrby separating the guard or any l'iortif'm of Athe lantern, or at the bottom after; the oiI-eup-is removed,rsubstantially as, here..
inafter specified.
To enable those skilled in the art to uiic'ler'f'y stand how to construct and use my invention, l. will proceed to 4describe the same with par- I ticularity', making reference in so doing to the aibresaiddrawings, in which-- Figure l represents a vertical central section of my invention; and Fig. 2 is a similar'vicw, showing a different construction ofthe interior-globe support.
Similar lettersV et'l reference inthe different fi gares denote the same parts of my invention. Y
A represents the lantern-base, in which a removable oil-cup, D, is secured'iu any suitable 'manner 5 B, the lanternguard, attached in any desired manner tothe upper part of said base A; and C, the lantern-top, hinged at I1, or secured in any other suitable manner, to the top of the guard B, as shown. E represents the ordinary lautern-globe, secured in the lanterncone of the burner to the dame, thea-ir passing freely into said inner globe cxtcrlor to the cone, between the said cone and the inner edge of the diaphragm M, as shown. The upper end of the said inner globe may be provided with a metallic top, G, passing up through a central orifice in the horizontal partition L, which thus forms a support to keep said globe in the proper position. rlhe said plate L 1s provided with holes c, connecting the chamber K in the lanterntop with.the space between .the globes, said chamber having no openings to admit the external air, receiving only the upward current through the inner globe, which de scend's through the apertures c in the partitionA L, and out through the openings d 1n the lantern-top below said partition L, when the Ianytern is stationary, or down through the space between the globes and out through the openings m and f, as shown at the lower part oi the :lantern in Fig. 1, when the lantern is swinging from side to side or moved suddenly upward. l In Fig. 2 the plate which supports thc inner globe is formed at the center in such manner as to constitute the cone for the burner, as shown at P, p p, at the b'ase of said conc, being apertures to admit air into said inner globe, Serving the same purpose as the space between the cone and the plate M in Figp-l. The burner also represents, in Fig. 2, a round wick, lnstead of a dat one.` thus rendering the inner globe much less liable to break, as all .parts ot' the flame are equidistant from the perimeter ofthe globe.-
Having described the construction of m y .1nvention,iI will now proceed to describe the op.
yeration of the same.
When the lantern is stationary, the inner globe acting as a dra't-inducer, a current of air passes up through the apertures e e bcneath the cone and the space immediately extcrior to the cone, into the inner globe, and thence into the chamber K, whence it passes down through the openings c in the plate L, and out at the openings d d, thus securing a uniform and continuous current of fresh air to the burner, as desired. When the .lantern is moved suddenly downward, the air-current is' induced through the holes f at the sides of the base and the holes a inthe bottom of the lantern, especially the latter, most of it passing into and through the inner globe, on account of the rising ot' the heated air within, and some into the space between the globes, both currents passing upward an d out at th e top through the openings `When the lantern is moved point between the globes, to pass into said inner globe, thus keeping a constant upward current' of fresh air through the said inner globe, as desired. When the lantern is oscillated or swung from side to side, the ascending current in the inner globe and the downward current between the globes are maintained in the same 11131111612 The essential feature of my invention, so far as the regulation ofthe air-currents above described is concerned, eonsistsin passing the top of the inner` globe far enough above all the openings in the top of the lantern to admit eX- ternal air to prevent the downward currents aforesaid from passing into the top of the inner globe. The same result would be secured by placing a dome or cap over the top of the inner globe, extending itssides below 'the top of said globe7 even though the lantcrn-top should be perforated above the top of the inner globe, as the practical effect of such arrangement Would -be to bring the openingsbelow the top of the globe, so far as their ei'ect thereupon is concerned.
I will be Observed, from the foregoin descri =tiou of the construction `of the iaiem thatthe'oil-cu may be removed from thesame without distur iu g the interior globe.
Having des ibed heconstruction and operation of myin fentioi ,I will proceed to specify what I claim .r ud desire to secure by Letters Patent. 'f
1. I claim extending the top of the inner' globe, F, above the holes d in tliculautern-top, substantially in the manner and for the pur.
poses specified.
2. I claim supporting the said inner globe in such a manner that the oil-cup can be removed from the lanternI without disturbing said globe, substantialbT LS Specified. l
3. I claim so constructing a lantern that the interior globe can be removed from the lantern independently.of the oil-cup, substantially as described. l
