BURNER-FASTENING.

SPECIFICATION forming part of Letters Patent No. 487,455, dated December 6, 1892.

Application tiled March 3, 1892. Serial No.423,587. (No model.)

T0 all whom it may concern:

Be it known that I, BERNARD T. STEBER, a citizen of the United States, residing at Utica, in the county of Oneida and State of New York, have invented a new and useful Improvement in Burner-Fastenings for Lamps and Lanterns, of which the following is a specification.

This invention relates to lamp or lantern burners which are seated in slip-collars or u nthreaded sockets in the top of the oil-pot, and has the object to provide a fastening which is simple and inexpensive in construction, and which securely holds the burner in its socket.

In the accompanying drawings, Figure l is an elevation of the lower portion of a tubular lantern provided with my improved burnerfastening. Fig. 2 is a fragmentary vertical section ofthe burner and connecting parts on an enlarged scale. Fig. 3 is a horizontal section in line x Qt, Fig. 2, looking upward. Fig. 4 is a vertical section of the burner and connecting parts, showing a modified construction of the burner-fastening. Fig. 5 is a bottom plan View of the burner cone and spring shown in Fig. 4.

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

A represents the oil-pot of a tubular lantern, and B the unthreaded burner-socket, secured in the top thereof.

O represents the annular air-chamber, surrounding the socket, and D the air-tubes, connected with the air-chamber.

E represents the burner, having its lower unthreaded portion constructed to fit snugly in the socket B.

F represents the burner-cone, which is usually made detachable from the burner, and G is the perforated plate, which rests upon the cone and supports the globe.

H represents a iiat bow-spring secured centrally to the outer side of the cone and having its ends arranged on diametrically-opposite sides of the same. The ends of the bowspring are provided with catches I, which pass inwardly through openings j in the side of the cone and engage with ears or shoulders la, formed on the inner side of the air-chamber. Each of the catches consists of a horizontal or main portion l, arranged in one of the openings in the cone, a depending arm m, formed at the outer end of the main portion and secured to one end of the bow-spring, and a depending arm fn, formed on the inner end of the main portion and provided at its lower end with an ou tWardly-projecting abrupt face o, and an inwardly-projecting inclined face p below the abrupt face. The ears 7c arel preferably formed by bending a portion of the upper edge of the air-chamber inwardly at right angles to the side of the air-chamber. Upon inserting the burner into its socket and lowering the cone upon the burner and airchamber the catches are forced inwardly by the inclined faces engaging against the ears of the air-chamber until the abrupt faces have passed below said ears, when the bowspring sp reads the catches and causes the latter to engage with their abrupt faces against the lower sides of the ears, thereby securely holding the burner in its seat.

The burner-cone is readily detached from the lantern by pressing both ends of the bowspring inwardly, so that the catches clear the ears of the air-chamber. The burner-cone is secured in place by simply lowering it upon the air-chamber and the burner proper and without requiring any turning movement of the burner-cone. The position of the burnercone is determined by the usual notch formed in the lower edge to straddle the wick-raiser shaft.

The burner proper may be secured to the cone; but ordinarily the cone is detached from the burner, and when that construction is employed the burner is confined in its socket by my improved fastening by simply locking the cone to the air-chamber.

As the burner and cone are placed in position and locked by a straight downward movement without turning, it is impossible to seat the burner-cone on the air-chamber without securely locking the cone and the burner in position.

In the modified construction represented in Figs. 4 and 5 the bow-spring is arranged on the inner side of the cone. In this construction the catches are formed integrally with the bow-spring, and thelatter is provided near the catches with thumb-pieces q, which project outwardly through openings in the cone and permit the catches to be manipulated.

IOO

I prefer to Construct the bow-spring in one piece, as shown; but it is obvious that two half-springs, each provided with one of the catches, may be substituted for the single spring carrying both catches.

I claim as my inventionl. The combination, with the oil-pot having u burner-socket, an air-chamber surrounding said socket and provided with inwardly-projecting ears, and the burner, of a burner-cone resting upon the air-chamber and a horizontal bow-spring secured to the @one and provided at its ends with shoulders which engage with the ears of the air-chamber, substantially as set forth.
