CHARLES J. HIGGINS, OF I'IALLOWELL, MAINE.

LANTERN.

SPECIFICATION forming part of Letters Patent No. 417,026, dated December 10, 1889.

I Application filed September 25, 1889. Serial No. 325.075. (N0 model.)

To caZZ whom it may concern:

Be it know that I, CHARLES J. HIGGINS, a citizen of the United States, residing at Hallowell, in the county of Kennebec and State of Maine, have invented a new and useful Improvement in Lamps and Lanterns, of which the following is a specification.

This invention relates to that class of lamps and lanterns in which a metallic oilpot is .used, and has for its objects to simplify the construction of the burner and to provide simple means for indicating the height of the oil in the oil-pot.

My invention consists, to that end, of the improvements which will be hereinafter fully set forth, and pointed out in the claims.

In the accompanying drawings, Figure l is a sectional elevation of the lower portion of a tubular lantern provided with myiniprovements. Figs. 2 and 3 are horizontal sections in line 00 0;, Fig. 1, one looking upward and Figs. 4 and 5 are sectional elevations at right angles to each other of the filler of the oil-pot.

Like letters of reference refer to like parts in the several figures.

A represents the oil-pot of a tubular lantern; B, the air-chamber secured to the top of the oil-pot, and C O are supply-tubes which open into the sides of the air-chain- D61.

D represents the fiat wick-tube, which is arranged within the air-chamber and seated with its lower portion in a slot formed in the top of the oil-pot. The wick-tube is preferably composed of two parts or sections, the lower part cl entering the slot of the oil-pot, in which it is secured by soldering or otherwise, and the upper part (1' being detachably secured to the lower part by a slip-joint or other suitable means, so that the upper part will remain securely in place on the lower part in the ordinary conditions of use of the lamp or lantern,but can be removed from the lower part when the upper portion of the burner requires renewal and forothcr purposes.

E represents the perforated gallery or flange which surrounds the upper .portion of the wick-tube and is secured thereto by soldering or otherwise. This gallery is provided with air-openings of any suitable form, and has formed on it depending ears e e, in which the shaftGof the wick-raiser is journaled. These ears are preferably partially severed by stamping from the plate of which the gallery is formed, and are then bent down. The wick-raiser shaft maybe arranged in notches g g, formed in the top of the air-chamber, on opposite sides of the burner, or it may be arranged above the edge of the air-chainber.

H represents the burner-cone which surrounds the wick-tube, and which rests with its laterally-extending base portions upon the air-chamber B. The base of the burner-cone is provided with a marginal flange h, which overlaps the top of the air-chamber. This burner-cone may also rest upon the edge of the perforated gallery.

I represents the perforated plate which sur rounds the burner-cone, and J represents the globe.

I-Ieretofore in this class of lamps and Ianterns the wick-tube was surrounded by a is known as the slip-burner, or the jacket and socket were provided with screw-threads and secured together. In either case the burner occupied considerable space and obstructed the air-chamber in which it was arranged and from which the air passed upwardly through the perforated gallery to the flame. Furthermore, the slip burner construction required devices for preventing the burner from turning in its socket, while the screw-fastening necessitated the employment of a jointed wick-raiser shaft in order to enable the wick-raiser to be arranged below the top of the air-chamber. It is also difficult in these prior constructions to prevent the es cape of oil upwardly from the oil-pot, because both the slip-burner and the screw-burner have no oil-tight connection with the oil-pot. In my improved construction the jacket surrounding the wick-tube is dispensed with and the latter is inserted directly into-the slot formed in the top of the oil-pot. This enlarges the air-space in the air-chamber, prevents the burner from turning, and permits a reduction of the diameter and height of the burner-cone and air-chamber, thereby reducing the height of the lamp or lantern. The construction of the burner and oil-pot is also much simplified and the costs of these parts materially reduced. When the wick-tube is secured in the slot of the oil-pot by soldering, no oil can escape upwardly except through the wick, and leakage is prevented.

represents the opening formed in the top of the oil-pot for supplying the same with oil, and K is the internally-screw-threaded collar which is secured in this opening. K represents an eXternally-screw-threaded stopper by which this opening is closed.

L represents a float which is arranged in the oil-pot underneath said opening, and which rises and falls with the level of the oil in the oil-pot, so that the rise of the oil-level can be readily observed in filling the oil-pot, and overflow at the filler-opening be prevented. This float is constructed of cork or other buoyant material, and is preferably painted in a conspicuous color, so that it can be easily seen. This float is hung by an arm Z to a hinge-axis M, secured to the under side of the top of the oil-pot. The hingeaXis consists of a bent wire, which is formed or stop m, which holds the float slightly out of a perpendicular position toward the filleropening 70, so that the float is compelled to rise toward the filler-opening, and is prevented from rising on the opposite side of its pivot, where it cannot be seen.

My improvements are particularly desirable for use in tubular lamps and lanterns; but some of them may be advantageously applied to lamps and lanterns of other styles.

I claim as my invention 1. The combination, with the oil-pot havingan elongated opening in its top, of a flat wick-tube seated in said opening, an airchamber secured to the oil-pot and surrounding said elongated opening, air-supply passages communicating with said air-chamber, and a burner-cone surmounting said Wicktube and air-chamber, substantially as set forth.

2. The combination, with. the oil-pot hav wick-tube seated in said opening, an airchamber secured to the oil-pot and surrounding said elongated opening, air-supply passages communicating with said air-chamber, a perforated gallerysecured to the Wick-tube and surrounding the same, and a burner-cone ing an elongated opening in its top, of a flat surmounting the wick-tube and resting upon the air-chamber, substantially as set forth.

3. In a tubular lantern, the combination, with the oil-pot, of an enlongated socket attached to the oil-pot, and a removable elon gated wick-tube seated in said socket,whereby the Wick-tube is kept from turning, substantially as described.

4:. The combination, with the oil-pot having an elongated opening in its top, of a wicktube composed of a lower portion permanently secured in said opening, and a detachable top portion, a perforated gallery carrying the wick-raising shaft secured to said top portion, and a burner-cone, substantially as set forth.

5. The combination, with the oil-pot having an elongated opening in its top, of a wicktube composed of a lower portion permanently secured in said opening, and a detachable top portion, a perforated gallery secured to said top portion, an air-chamber secured to the oil-pot and surrounding said elongated opening, air-supply passages communicating with said air-chamber, and a burner-cone resting upon said air-chamber, substantially as set forth.

(5. The combination, with the oil-pot and the wick-tube secured thereto, of a perforated gallery secured to the wick-tube and provided with ears, and a wick-raiser shaft journaled in said ears, substantially as set forth. at one end with a downwardly-extendin g arm 7. In combination with an oil-pot having ;an elongated opening in its top, an elongated wick-tube arranged therein, said wick-tube carrying a shaft and ratchet-wheels for raising the wick, an air-chamber formed by the top of the oil-pot, side walls, and the cone .with its supporting-plate, said wheels being inelosed and protected therein, air-tubes entering the said air-chamber, and the globe surn'iounting the. said air-chamber, substantially as described. v

8. In a tubular lantern, the combination,

with the oil-pot having an elongated opening in its top, of an elongated wick-tube arranged therein, whereby the position of said wicktube is kept in its proper relation with the airtubes and other parts of the lantern, an airchamber on top of the oil-pot and surrounding said opening, air-tubes connected with said air-chamber, and a burner-cone surmounting said air-chamber, substantially as described.

WVitness my hand this 21st day of September, 1889.

CHARLES J. HIGGINS.
