HAND-LANTERN.

SPECEICATION forming part of Letters .Patent No. 717,801, dated January 6, 1903. Application led June 22, 1901. Serial No. 65,543. (No model.)

T0 all whom, t may concern: n

Beit known that I, FRANK V. BENSON, a citizen of the United States, residing at Topeka, Shawnee county, Kansas, have invented certain new and useful Improvements in Hand-Lanterns, of which the following is a specification.

My invention relates to that class of handlanterns in which the air is admitted above the globe to feed the light and is separated from the escaping gases, all of whichwill more fully hereinafter appear; and it relates particularly to the means for producing and maintaininga clear light in all kinds of wind and weather.

The principal object of my invention is to provide a simple, economical, and efficient hand-lantern with means-wherebyit can be used in all kinds of weather and in the heaviest Winds.

A further object is to provide means for producing clear light under all conditions and for preventing the light from becoming eX- tinguished by the wind or sudden jerks or movements to which it may be subjected.

A further object is to provide means for ad-` mitting the air for the burner within the globe at the top of the lamp and separating it from the escaping gases.

A further object is to provide a lue for conducting the escaping gases to the outer air, which also acts to evenly distribute the admitted air, so as to maintain an even temperature of the globe.

A further object is to provide means for ad-v justing and trimming the wick without re-V moving they burner or any other part or parts. Other objects of the invention will appear from an examination of the drawings and thefollowing description and claims.

The invention consists in the features, com` binations, and details of construction hereinafter described and claimed.

In the accompanying drawings, Figure lis an elevation of a lantern constructed in accordance with these improvements, shown partly in section; Fig. 2, an elevation of the line-cap detached from the lantern.

In constructing a lantern in accordance with my improvements I provide a frame portion c, globe b, and bail c of the ordinary and well-known type. Upon the frame portion is mounted an outer hood d, which is provided with perforations e for permitting air from without to enter and perforationsf for permitting the gases to escape therethrough, as hereinafter described. It is desirable that the air which is fed to the dame be kept in as pure a condition as possible and kept as `far as possible from contact with the escaping gases; also, that suitable means be provided for permitting the products of combustion to escape. To accomplish these results, a tine-cap is provided composed of a tubular portion h, an upper cowl portion il, and an .outer depending annular ange portionj, all formed, preferably, in one integral piece. The iiange portion is adapted to extend over and inclose the top of the globe and the tubular iiue portion to be inserted within the globe and form a passage g between the oute side of the tine and the inside of the globe for the admission of .air to the burner. The flange portion is provided with a plurality of perforations k, which when the parts are in position are on substantially the same plane with perforations e in the lantern-hood and form inlet-passages for the admission of air. For the purpose of further insuring the division of the incoming air from the escaping products of combustion the luecap is provided with a second outwardly extending ange Z, which extends to the inner surface vof the lantern-hood between the inlet-perforations e and the outlet-perforations f in the hood, and thus provide a separating-partition. It will thus be seen that the flue-cap when in position is directly over the flame and is provided with a hollow annular portion h, above mentioned, extending downward into the globe, and that the cap proper extends from the top of the downwardly-extending hollow portion upward beyond the inlet-perforations and with its flange l and the hollow downwardly-extending portion acts to eftectually divide the incoming air with its quantity of oxygen from the escaping gases.

In order to prevent the light from being affected by air flowing in through the out-letperforations, the upper portion of the lluecap, as shown, is made in the form of a truncated cone, the base joining the central down- Wardly-depending hollow liuc portion and forming in connection therewith a passage IOO the area of which diminishes as it approaches the top of the cone. Any blast of air from the outside is thus dissipated and its force destroyed by the conical top of the inner fluecap or hood. To accomplish the same purpose with reference to the perforations in the flange through which the air-supply is admitted, the bottom of the tubular portion is provided with an expanded end fm, which causes the incoming current of air to pass along the sides of the chamber formed by the globe and backward in such Va manner as not to come in contact with theiiame until the downward current is dissipated. This construction of the iiue also acts to heat the incoming air, while at the same time dividing it from the escaping gases, as above mentioned, whereby more perfect combustion is aiforded and the cooling of the oil by the admission of cold air at the bottom of the globe is avoided.

In order to afford means for yieldingly holding the flue-cap in position, I provide a springcatch n, on which is mounted a shouldered lug o, having an end p, which passes through an oblong slot q in the outer hood and is held therein by the tension of the spring. On the opposite side of the due cap a stationary shouldered lug o', having a similar extended end p', is arranged to engage with a similar slot 0 (not shown) on the opposite side of the outer hood. A helical spring r is mounted between the cap and the upper portion of the hood and iiue, so as to hold the flue-cap portion in yielding contact with the top of the globe and allow for any irregularity in the length of the globe. The lantern hood or cover is fastened to the frame in the ordinary and well-known manner.

To insure the admission of air to feed the fiame, notwithstanding the possible failure of the perforations e and 7c to register, the line-cap is made of a diameter slightly smaller than the inner diameter of the lantern-hood, wherebya passage is formed between the outside of the fine-cap and the inside of the hood for the admission of air to the perforations in the cap. The inlet-perforations in the cap thus communicate with the outer air independently of the inlet-perforationsin the hood.

I claim- 1. In a lantern of the class described, the combination of a frame, a perforated hood thereon extending outward over the top of the globe, a globe within the frame, a flue-cap within the hood extending outward and downward beyond the top of and in contact with the globe and between it and the hood and provided with inlet openings in its outer downwardly-extending portion, and a hollow depending portion extending into the globe, substantially as described.

2. In a lantern of the class described, the combination of a frame portion, a hood extending outward over the top of the globe and having inlet and outlet perforations therein, a globe beneath such hood, a ilue-cap provided with a hollow depending portion extending within the globe, an outwardly-extending annular tlange upon the flue-cap extending to the hood and forming a partition between the inlet and outlet perforations in the hood to divide the incoming air and escaping products of combustion, and a ange also forming a part of such inner flue-cap extending from a point above the globe downward beyond the top of and in contact with the globe and provided with a plurality of inlet-openings, substantially as described.

3. In a lantern of the class described, the combination of a frame, a globe mounted within the frame, a hood mounted on the frame provided with inlet and outlet passages, a flue-cap arranged within the hood having a hollow depending portion extending downwardly into the globe, and an annular flange portion encircling the globe extending upward beyond the top of the globe and between it and the hood and provided with inlet-openings, such hollow depending portion serving to divide the incoming air and escaping products of combustion within the globe, substantially as described.

4. In a lantern of the class described; the combination of a frame; a globe mounted therein; an outer hood provided with inlet and outlet openings and mounted above the globe; and a flue-cap mounted within such outer hood and provided with a hollow upwardly-extending truncated cone-shaped portion arranged small end upward, a depending tubular portion extending downward into the globe, and a perforated flange portion cxtending from a point above the globe downward beyond the top thereof and between such globe and the outer hood, substantially as described.

5. In a lantern of the .class described; the combination of a frame; a globe mounted therein; an outer hood provided with inlet and outlet openings and mounted above the globe; and a flue-cap mounted within the outer hood and provided with an outwardlyextending portion forming a partition between the inlet and outlet openings of the outer hood and hollow truncated cone-shaped portion extending upward beyond such partition and adjacent to the outlet-openings of the outer hood, a hollow depending portion extending downwardly beyond such partition into the globe, and a perforated annular flange portion extending from the partition downward beyond the top of the globe and between it and the outer hood, substantially as described.
