IM PROVEMENT IN LANTERNS.

specification forming part of Letters Patent Nojaoalae, dated september 17,1878; appiic'ationniea August 19, 1878. v

To all whom it may concern Beit known that I, ALFRED L. BARON, of Bellaire, in the county of Belmont and State of Ohio, have invented a new and useful Improvement in Lanterns; and I do hereby declare that the following is a full all@ exact description of the same, referenceA being had to the accompanying drawings, and to the letters of reference marked there'on.

rlhe object I have in view is to apply to the square lantern with at glass sides held in a frame, or to any fiat-sided lantern, the principle of feeding air to the dame and counterbalancingthe air-currents employed in the Buckeye 7 lanterns, and covered by Patent No. 191,401, granted May 29, 187 7 to Evan F. Cash and myself, such principle being to admit fresh air taken from the top of the lantern through connecting chambers exclusively into the cone, and other fresh air through the sides of the base around and outside of the cone, the two currents being kept separate and apart till they reach the flame.

My object is, further, to produce a lantern possessing all the advantages of the Buckeye lantern in the way of a steady light, protected so that it cannot be put out by wind or rain, or by any 'sudden movement of the lantern, but which will be much simpler in construction and very cheap to manufacture.

My invention therein consists in the construction of the square or ilat-sided lantern to feed air to the flame and secure a perfect counterbalance of the currents, and in the various combinations of parts for effecting this purpose; and, further, in the means for holding the burner in position, which permit ready access to the same for lighting or trimming, as fully hereinafter explained.

In the drawings, Figure 1 is a perspective view; Fig. 2, a central vertical section; Fig. 3, a crosssection, looking downwardly, and Fig. 4, a top view of the oil-reservoir removed from the body of the lantern.

Like letters denote corresponding parts.

A is the oil-reservoir, of rectangular form, as shown, and having a central opening in its top, in which is set the burner B without screw-threads, and which is also used for lling the reservoir with oil. Around this opening, inside the reservoir, is placed a tubefa, extending nearly or quite to the bottom of the reservoir, and slotted upwardly from its lower edge, so as to confine the loose end 'of the wick in the center of the reservoir, the ivick nearly filling the tube, and, while allowing the oil to iiow freely into the wick, preventing the same from'being forced up around the burner by any movement of the lantern.

O is the square supporting-plate, carrying the body of the lantern and resting over the oil-reservoir upon the vertical plate b, which incloses and forms the walls of the air-chamber leading to the burner. l

rEhe wick-raising stem rests in a slotin 011e side of this plate, and projects outwardly far enough to be turned conveniently by the i11- gers. y v

The.supporting-plate is hinged to the upper edge of the plate b by means of a wire, c, which is soldered to the overturned edge of the top plate of the oil-reservoir. At the opposite side of the supporting-platea straight wire, cl, is held in the overturned edge of the securely and rigidly together, but allowing the body to be thrown back on they hinge for filling the reservoir or trimming or lighting the wick.

The cone B is permanently attached to the upper side of the supporting-plate over a central opening, and around this opening the supporting-plate presses upon the case of the burner when locked tothe oil-reservoir, and holds such burner securely in position.

To the corners of the supporting-plate is rigidly attached the vertical frame D, and upon this frame is mounted the top E, with inclined sides, and having a defiecting-cap, El. The bail E2 is pivoted in the sides of the top.

The frame D has its plates bent to form vertical channels, in which slide the liat glass plates F, extending from the top D to the supporting-plate C. On two sides ot' thela-ntern are placed inner plates, F', forming an airspace, G, between the outer and inner glass plates.

The plates F' extend up inside the top, back of air-openings e in the top, which have deilectors e', so as to prevent the air entering such openings e from gaining admittance to the central space of the lantern and directing the same down through the air-chambers G between the glass plates.

The supporting-plate at the bottom of each air-chamber G has one large or a number of small openings, j', through which the air passes into the air-chamber G' on top of the oilreser voir. The supporting-plateresting on the walls Z) completes the air-chamber G', and makes a connection between the air-chambers G and the interior of the cone.

The walls b, or plate, on two opposite sides of the lantern extend inwardly on radial lines close to the burner, so as to leave spaces open to the surrounding air between portions of the supporting-plate and the top of the oil-reservoir.. These parts of the supporting-plate so exposed are perforated, as shown at g, and through these perforations air passes up into the lantern around the outside of the cone,the direction of such currents being shown in Fig. 2. By this construction, when the wick is lighted the air is caused to circulate, and the currents counterbalanced the saine as in the Buckeye lanterns, and upon precisely the same principle. The flame is also protected from being blown or put out by the elements or by any violent movement of the lantern.

This lantern is very cheap, a great saving being eiected by substituting the glass plates, which cost very little, for the globes, and all the other parts of the lantern being formed and secured together by easy and rapid operations.

It is' evident that this square lantern could be made with double plates, having air-chambers between them on all four sides ofthe lan iiat sides; andthat the air-chamber G' could be made quite differently-as, for instance, secured to either the upper or lower sides of the supporting-plate, or extended in tubes through the oil-reservoir, without departing from the spirit of my invention.

What I claim as my invention isl. In a square or other flat-sided lantern having double glass plates, the combination of one or more air-chambers between such plates conducting air to the interior of the cone, and openings to admit air to the iiame outside of the cone, the two currents being kept separate and apart till they reach the iiame, substantially as described and shown.

2. In a square or other iiat-sided lantern, the combination of the double plates F F', forming air-chambers G, the air-chamber G' on top of the oil-reservoir, and the openings g in the supporting-plate, substantially as described and shown.

3. In a square or other iiat-sided lantern, the combination of the plate b, forming the walls of the air-chamber on top of the oil-reservoir, with the hinged supporting-plate resting on such plate and completing the air chamber, substantially as described and shown.

4. In a square or other flat-sided lantern, the combination,with the top D, having airopenings e, of the outer glass plates, F, terminating below such openings, and the inner plates, F', extended upwardly behind such openin gs,substantially as described and shown.

5. The combination, with the oil-reservoir, of the burner B, set into an opening iu the same, and the hinged supporting-plate holding such burner in position, substantially as described and showin This specification signed and witnessed this 5th day of August, 1878.
