ALONZO L. EDWARDS, OF WHEEL-ING, WEST VIRGINIA, ASSIGNOR TO WHEELING STAMPING COMPANY, OF WHEELING, WEST VIRGINIA, A CORPORATION OF WES-T VIRGINIA.

Application filed September 16, 1913.

To all whom it may concern Be it known that I, ALoNzo L. EDWARDS, a citizen of the United States, and a resident of lVheeling, in the county of Ohio and State of est Virginia, have invented a new and useful Improvement in Tubular Lanterns, of which the following is a full, clear, and exact description,reference being had to the accompanying drawings, in which Figure 1 is a side elevation partially in section of one form of my improved lantern, showing the globe in its elevated position in full lines and in its lowered position in dotted lines. Fig. 2 is a sectional view on Fig. 3 is a side elevation of the globe retainer. Fig. 4 is a sectional view through the dome and globe retainer of a modfiied form.

This invention relates to an improvement in tubular lanterns, and is designed to provide a cheap and eflicient construction in which the parts can be readily assembled- Another object of my invention is to provide a lantern of this character in Which the globe retainer is held in position on the globe by means of a spring which is seated within the air chamber in the dome, and within a chamber formed by an additional shell on the globe retainer, whereby it is protected from the heat of the burner; also in which the parts are so arranged that the lower end of the spring is always below the lower end of the dome, By the use of an arrangement of this character, I am enabled to employ a very much longer spring than has heretofore been used, without increasing the height of the dome.

Another object of my invention is to so arrange the globe retainer or movable section of the chimney that the globe can be raised a sufficient distance to permit the burner to be removed without removing the globe from the retainer.

vThe precise nature of my invention will be best understood by reference to the accompanying drawings, which will now be described, it being premised, however, that various changes may be made in the details of construction and the general arrangement of the parts without departing from the spirit and scope of my invention, as defined in the appended claims.

Referring to the accompanying drawings, the numeral 2 designates the oil well or pot, and mounted on the top of this well is a Specification-of Letters Patent.

TUBULAR LANTERN.

burner 3. Connected to the burner 3 and the outer shell at of a dome at the top of the lantern are the air tubes 5 for supplying air to the burner. The dome is also provided with an inner shell 6, which may be connected to the outer shell at the upper end in any desired manner. In the drawings, I have shown the outer shell provided with an inwardly extending flange 7 at the upper end thereof, which is connected to the upper end of the inner shell 6. This flange is provided with a plurality of slits for receiving the lower ends of the legs 8 on a top plate.

10 designates openings between the legs 8 through which the products of combustion from the lantern pass. The top plate 9 and the legs 8 are formed integrally with each other. The lower ends of the legs are passed through the slots in the flange 7 and are then turned over to secure the top plate in position.

Extending outwardly from the lower end of the outer shell l is a flange or skirt 11, and connected to this flange is an annular plate 12, which is provided with openings for admitting air to the air space formed between the shells 4 and 6. The annular plate 12 is also provided with an upwardly extending flange 13, which is concentric with the shells 4 and 6.

Telescopically mounted on the inner shell 6 of the dome is a globe retainer having inner and outer shells 14 and 15, respectively, which are connected to each other at their lower ends and are also connected to a flange member 15 the lower end of which is arranged to receive the top of a globe 16. The lower end of the globe 16 is supported on a plate 17 to which is connected the usual lifter lever 18, pivoted to projections secured to the air tubes 5. The flange member 15 is provided with a plurality of openings 19 for admitting fresh air to the chimney above the globe 16. The chimney of the lantern is formed of the inner shell 6 connected to the dome and by the inner shell 14 of the globe retainer. The shell 6 is provided with a plurality of openings 20 and 21 for permitting some of the products of combustion to pass to the air chamber between the shells 4 and 6. The lower end of the flange member 15 is provided with a reinforcing wire 22 which is bent outwardly at two points, as indicated at 22*, to form guide loops and which surround thev loop guides 23 connected to the-air tubes of the lantern. These guiding loops are arranged to form stops for the globe retainer when the globe is removed from the lantern.

24 designates a spring surrounding the shells l and 1a, and seated between the flange 7 on the shell I and the flange 15*, or connecting member between the inner and outer shells 14 and 15 of the globe retainer. By the use of a construction of this character, I am enabled to use a very much longer spring, as the lower end of the spring is below the bottom of the dome when the globe is in its elevated position. Heretofore in lanterns of this general type, the lower end of the spring was seated on an annular flange, which was always above the lower end of the dome, so that the spring space was necessarily limited.

In Fig. t I have shown a construction similar to that shown in Fig. 1, and to which I have applied the same reference numerals with the letter a aflixed. This construction differs from that shown in Fig. 1 in that the inner shell 14: of the globe retaining member is within the inner shell 4 connected to the dome. In both of these constructions the flange member 13 on the annular plate 12 forms guides for the outer shells of the, globe retainer.

The advantages of my invention result from the provision of a globe retainer for lanterns which is provided with a plurality of shells which form a spring retaining recess between the outer shell of the globe retainer and the inner shell of the dome or stationary member of the chimney. Further advantages result from the provision of means for directly securing the upper end of the inner shell of the dome to the upper end of the outer shell thereof.

I claim:

1. A tubular lantern having a dome provided with an inner and an outer shell, there being an annular air space formed between said shells, a closure for the top of said space extending downwardly and outwardly from the inner shell to the outer shell, and a top plate having a plurality of downwardly eX- tending projections secured to the closure adjacent to the outer edge thereof, there being a space between the closure and the top plate; substantially as described.

2. A tubular lantern having a dome provided with inner and outer shells, there be ing an annular air space formed between said shells, a closure for the top of said space connected to both shells, air tubes connected to the outer shell and communicating with the air space, a movable globe retainer having inner and outer shells, the inner shell being slidably connected to the inner shell of the dome, and a spring seated betweenthe inner and outer shells of the dome and the inner and outer shells of the globe retainer; substantially as described.

3. A tubular lantern having. a dome provided with inner and outer shells, the upper edge of the inner shell extending considerably above the upper edge of the outer shell, there being an annular air space formed between said shells, a closure for the top of said space extending downwardly and outwardly from the top of the inner shell to the top of the outer shell, and a top plate having downwardly extending projections connected to the closure adjacent to the outer edge thereof, there being a space between the closure and the top plate; substantially as described.

4. A. tubular lantern having a dome provided with inner and outer shells, there being an annular air space formed between said shells, a closure for the top of said space connected to both shells, air tubes connected to the outer shell communicating with the air space, a movable globe retainer having. inner and outer shells, the inner shell being slidably connectedto the inner shell of thedome, an annular plate connected to the lower-end of the outer shell of the dome and forming a guide for the outer shell of the globe retainer, and a spring engaging the dome and the globe retainer for holding the globe retainer in its down position; substantially as described.

In testimony whereof, I have hereunto set my hand.

ALONZO L. EDWARDS.
