Specification of Letters Patent.

Patented Jan. 7, 1908.

Application filed April 5, 1907. Serial No. 366.631.

To all whom it may concern:

Be it known that I, GUSTAV STUBGEN, manufacturer, a subject of the King of Prussia, residing at Erfurt, Kingdom of Prussia, German Empire, have invented certain new and useful Improvements in Storm- Lanterns, of which the following is a specification.

This invention relates to a storm-lantern so constructed that for cleaning purposes access to the air-supply conduits can be had from the air-chamb er surrounding the burner.

An essential feature of the invention is that the tubular burner-socket is so constructed that a brush can be introduced into the lower end of the air-conduit communicating with the air-chamber.

Various contrivances have been proposed to allow of cleaning the air-conduits of storm lanterns, but hitherto none of these has been completely successful. In some cases the air conduits have been divided or provided with flaps to allow of the insertion of a brush, or a central tube above the chimney has been provided with a removable shutter. The arrangements are unsuitable and inconvenient, since shutters and the like are liable to be lost so that the cleansing apertures are exposed and the lantern is extinguished by air currents.

To allow of thoroughly cleaning the airconduits the tubular socket carrying the burner is in the present invention so constructed that a brush can pass over the said socket into the lower end of the conduit to be cleaned.

Several embodiments of the invention are illustrated in the annexed drawing, in which:

Figure 1 is a cross-section with a portion thereof shown in dotted lines of the lower part of the air-tubes and burner socket. Fig. 2 is a detail view of Fig. 1. Fig. 3 is a side view partly broken away. Fig. 4 is a section. Fig. 5 is a plan of a modified form.

In the drawings a socket c has lateral aperturesf opposite the orifices of the air-tubes 6, so that a brush can be easily introduced into the said orifices.

In the construction shown in Figs. 1 and 2 the air-chamber surrounding the burner is enlarged and provided with inwardly projecting lugs g which hold the burner jacket, gaps being provided opposite the air-tubes orifices to allow of introducing the brush. The construction of the burner-jacket shown in Figs. 1 and 2 allows of conveniently fastening the said jacket and the burner by means of elastic cylindrical sockets by which the jacket and burner are held securely in position, but in such a manner that they can be readily inserted and removed at will. An arrangement for this purpose is illustrated in Figs. 3 to 5. In this case the central aperture of the oil-reservoir, into which the lower part a of the burner a is inserted, is provided with an elastic, cylindrical flange h. The latter is rendered elastic by making longitudinal or transverse slots therein, so that resilient lugs i are formed. The burnerjacket is also provided with a cylindrical ase 01; adapted to be inserted into an elastic cylindrical socket m formed on the oil reservoir, the upper part of the latter being for that purpose bent into cylindrical shape and provided with resilient lugs 11. The burner and burner-jacket are thus supported by two sockets or seats h and m, and are held by friction. The burner-jacket is provided in the known manner with an inward projection which bears against the burner and holds the latter fast. Even in perfect darkness, and with hands stiffened by cold, the burner and burner-jacket can be introduced into their respective sockets, and the fastening thus made is very secure, though the parts can be readily disconnected at will. Accidental disconnection, as in the case of a bayonet fastening, does not take place when the lantern or oil-reservoir is knocked against a hard body.

What I claim .and desire to secure by Letters Patent is:

1. A storm lantern of the class described, comprising an oil reservoir provided with a plurality of sockets in the crown thereof, elastic lugs forming the walls of said sockets, a burner member mounted within one of the sockets and frictionally held in position by said lugs, and a cap mounted in the other socket and in frictional engagement with the elastic lugs formed in the wall thereof.

2. In a storm lantern of the class described, an oil reservoir, an air feed-chamber, said reservoir and chamber having sockets, elastic lugs formed in the walls of said sockets, and a cap and burner member mounted in the said sockets respectively and held in position by the said elastic lugs.

3. A lantern of the class described, comprising an oil reservoir having an air chamber in the crown thereof, air tubes in com munication with the chamber, said reservoir and air chamber having sockets provided In testimony whereof I have hereunto set with depending cylindrical flanges forming my hand in presence of two subscribing yieldable lugs, a burner mounted in one of Witnesses.

the sockets, and a cap mounted in the other GUSTAV STUBGEN. 5 socket, the said burner and cap being fric- Witnesses:

tionally held in the sockets by the yieldab-le PAUL TIOHMANN,
