To all whom it may coit'cem Be it known that I,,E1 GAR K;

Massachusetts, have j invented an Improve ment 1n Lanterns specification: t

Fig.

7 is a modified form of bottoin plate. I In the drawing, asdesignates the receptacle forthe kerosene or other oil. bis the burner; 0, the shaft to raise or-lower the wick, and d the elevated cone surrounding the burner, all jof, usual construction. M plate e extends laterally from, near the base :of' the burner to a ring, f, within the upper end of which is placed the globe 9'. Outside this ring is placed a deflectonh, substantially such'asshown in my Patent No'.,l44,200,- to force the air into the openings twlienjthe lantern is being swung orlifted,thereby counteractifng the descendingmotionofthe air within the globe, substantially such as: shown in my air feedingring is differently constructed, and is not providedwith holes, asthereinshown.

when the aircurrentoutside the lantern is such asito suck the-air from the interiortof the %the bprner, and there is no outside communicationwith' the atmosphere to, furnish air to x epia-(attainments, -ins lneisl' be "to bei'smothered.

:L o obvietth sI-ha ma a se esofa x Q iliary openings, 7:,in the lingfiimlnediately ,-ja b e p in s T earri tit ed Ewithin the ring f, separatesUthesetWo series of openingsk "i I'This feed-ringis shown bent or waved .at its interior portion,;to present althecurrent downward as to assist in'ffeeding The ,curved bottom Patent no. 144,200; butinithis' iiistanoe the" nan construction shown in the: Patent,,

1 lantern, such air is drawn 'theiefrdnitooQneeir ring rest upon the bottom plate, thereby leaving a series of radial passages opening toward the center of the burner. The air admitted at the openingsi is led through the passages under the feed-ring to the interior of the burner to supply it with air. Should the wind blow into such openings, the current will be checked a hole which may be made through the bottom plate for the passage of a match or other or retarded, and the air which does not pass up through the center of the burner will be forced, across under the open cone d, and, impinging upon the upper curved faces of the feed-ring, will rise upward between the cone and-.theinterior of the globe without impinging directly upon the outside of or blowing directly across the top of the burner. When the, air outside the lantern has such a motion with relation to the deflector as to suck the air from the interior outward, then, to supply air to the interior of the lantern and support combustion at the burner, I have provided the ring with a series of auxiliary air-passages, k, which admit air from the outside as the air from the inner side is exhausted through holes. This is a most important requisite of this my invention, as to the maintenance of combustion at the burner, and to keep at that point a proper supply of oxygen.

When,,however, the atmosphere is considerably disturbed outside the lantern, air coming in at the openings k isv apt to deflect the smoke or flame against the interior of the globe and blacken it. To obviate this I have placed above the feed-ring a smoke-preventing ring, 17. The flange g of this ring rests against the ring fat its interior, above the passages 70, and air entering such passages is checked by the depressed portion r of the ring 1;, and thence passesiuto the interior of the lantern at an intermediate position between the passages 7c and; the burner, whereby the body of air so. discharged is caused to ascend in a more central position, so that it does not defl'ect the flame and smoke against the interior of the globe opposite the burner, as would be the case under some conditions of the air outside the. antern, if the ring 12 wereomitted.

The bottom plate 0 is shown in Fig. I as concaved between its raised center and outer edge,

and it is provided with suitable openings 3, for

the discharge of water which may fall upon the bot om P a small-sized lanterns, however, I prefer to omit the raising of the bottom plate at its center, andshape it as shown in Fig. 7, wherein the bottom plate is shaped substantially as the interior. of a. saucer, with the exception of ai s,rnall ann lar bead or rim, 5,, which acts. w tli .an .;-eircess of air to raise it, and cause part of it to pass upward the globe out s de of the cone. With this form of plate, I prefer to provide it at bottom with a greater At itsnumber of holes than at Fig. 2, and the passages 0' will in such case be somewhat contracted. This bottom plate might bemade flat, it being provided outside the cone with an elevated annular ring, to operate as before described of Fig. 7.

Fig. 4 represents a modified form of feedring, the flange being waved as the interior portion of the ring, Such a ring would only cover a portion of the holes of the lower series located as at i, and those not covered would admit air between the feed and smokerings.

In Fig. 2 I have shown a device, t, 'to cover 1 fcomposed. of a plate,conc'aved at its. side the top of the globe, as at u,- and itis' provided with a.

flange, v, and below it. is an auxiliary flange, w,of greater diameterthan flanges. Between, this flanged plate u and the topof the globe and the flange w is an open space, 9, through which the air in the lantern ,rises and passes .111;. The plate a and theflanges t and ware so shaped with relation to eachother as to prevent too much air passing into the globe from the top.

In Fig. 6 the bail a; of the lantern is shown as connected with a frame, 3 pivoted to eyes 6., sustained by the oil reservoir or lanternbase. A portion, 7, of the .frame extended, across the top part of the 1antern,and provided with a projection, 8, engages the top, a. portion of the projection entering adepressed part of the cover, or vice versa; thereby hold ing the frame and top lockedjtogether. The openings 10(see Fig. 2 ).i'n the deflector permit. the passage of water. down through them.

. The rim 11, between th 'tttwmprae and the top of the receptacle (it, adds to, the strength or rigidity of the lantern. tniay, however, be omitted. f p

The devices herein described for supply ing and regulating the passage of air to the flame may be used in otheriapparatus wherein hydrocarbon oils are consumed.
