Specification of Letters Patent.

Application filed August 31, 1908. Serial No. 451,091.

To all whom it may concern:

Be it known that I, ALEXANDER H. HAND- LAN, Jr., a citizen of the United States of America, residing at the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Lantern Constructions, of which the following is a. full, clear, and exact description, reference being had to the accompanying drawing forming part of this specification.

My invention relates to the construction of the lower portions of lanterns, and it has for its object, the production of such portions of lanterns at a minimum cost, and without the employment of skilled labor, while at the same time, furnishing a more secure and ethcient connection between the lower parts of the lantern, namely, the base rim, the guard hoop or oil pot hoop and the oil pot pocket plate.

Figure I is a vertical section taken through the lower part of a lantern constructed in accordance with my invention. Fig. 11 is a vertical section taken through the lantern base rim, guard hoop, or oil pot hoop and oil pot pocket plate, with said members in the positions assumed previous to their being clamped to each other. Fig. 111 is a view similar to II, illustrating a modification. Fig. IV is a view of the parts shown in Fig. Ill after they are secured to each other. Fig. V and VI are views similar to F 111 and TV respectively illustrating another modification. Figs. VII and VIII are views similar to III and V respectively illustrating still another modification.

In the accompanying drawings: 1 designates the base rim of my lantern, see Figs. 1 and II. This base rim is in the form of an inverted dish, and it is provided with a central circular aperture 2, located in the top of the base rim, and adapted to receive the guard hoop 3. The guard hoop 3 serves also as the oil pot hoop, but it will be hereinafter designated merely as the guard hoop. The guard hoop is provided above its lower end with an outwardly projecting annular and horizontal bead 1 and it terminates at its lower end in an outturned annular flange 5. which is located beneath the bead 4 and between which and the bead is a portion of the guard hoop that occupies the central circular aperture 2 in the base rim 1 when the guard hoop is introduced into the base rim.

6 is the oil pot pocket plate located beneath the guard hoop and within the base rim 1. This oil pot pocket plate is provided at its edge with an upturned and inturned annular flange 7 adapted to seat beneath the top of the base rim 1 adjacent to its central circular aperture and to encircle the outturned annular flange at the lower extremity of the guard hoop 3.

In assembling the parts of my lantern that have been thus far described, the lower end of the guard hoop is introduced into the cen-' tral circular aperture in the base rim 1, so that its bead 1 will rest upon the upper edge of said base rim, and the outturned flange 5 of the guard hoop will occupy a position be neath the top of the base rim. The oil pot pocket plate is placed within the base rim and moved upwardly therein, until its upturned flange 7 encircles the outturned flange 5 of the guard hoop. Then, by the use of a suitable implement or machine, pressure is applied to the oil pot pocket plate adjacent to its edge and the guard hoop is held from movement during the application of such pressure whereby the outturned flange 5 of the guard hoop and the upturned and inturned flange 7 of the oil pot pocket plate are pressed tightly to each other beneath the top of the base rim of the lantern, so that the first named of said flanges is firmly seated between the last named flange and the top of the oil pot pocket plate, as seen in Fig. l. A secure interengaging flange joint between the guard hoop and the oil pot pocket plate is thus provided, and the base rim 1 is caused to be firmly clamped between said interengaging oint and the annular horizontal bead of the guard hoop above it, which serves as a resistance member to )revent upward movement of the base rim on the guard hoop. After the parts have been assembled and united in the manner described, they may be dipped in a suitable soft solder whereby the interstices at the point of connection of the parts are effectually closed.

In Figs. III and IV, I have shown a modification wherein the base rim 1 is provided at its top and around its aperture with a do-wnturned and outturned flange 1 and the guard hoop 3 is provided at its lower extremity with an outturned flange 5- that is adapted to seat within the flange 1 of the base rim. In this construction the bead upon the guard hoop is dispensed with. 6 is the oil pot pocket plate which is provided with the upturned and inturned flange 7 that corresponds approximately to the upturned and inturned flange of the oil pot pocket plate 6. The upturned and inturned flange 7 of the oil pot pocket plate is adapted to enter into a position between the top of the base rim 1 and its downturned and outturned flange 1 Vhen the parts just described have been assembled as illustrated in Fig. III, they are subjected to pressure with the result of causing the upturned and inturned flange 7 of the oil pot pocket plate to become embedded between the top of the base rim and its downturned and outturned flange 1, and the outturned flange 5 of the guard hoop will become embedded between the downturned and outturned flange 1 of the base rim and the top of the oil pot pocket plate, thereby producing the interengaging flange joint shown in Fig. IV.

In the modification shown in Figs. V and VI, the base rim 1 is provided at its top with an upturned and outturned flange l that surrounds the central circular aperture in the base rim and the guard hoop 3 is provided at its lower extremity with an inturned flange 5. The oil pot pocket plate 6 is provided at its edge with a downturned and inturned flange 7 that is adapted to be positioned between the upturned and outturned flange of the base rim and the inturned flange of the guard hoop. hen the parts justdescribed are subjected to pres-' sure, the interengaging flange joint is pro duced in which the downturned and inturned flange of the oil pot pocket plate enters into the upturned and outturned flange of the base rim and the inturned flange of the guard hoop enters into a position beneath the flange of the oil pot pocket plate, as seen in Fig. VI.

In F VII and VIII, I have shown another modification in which the base rim 1 is provided at its top with a central circul-ar aperture, but is unflanged at the location of this central circular aperture. The guard hoop 3 is provided at its lower extremity with an inturned flange 5 that is adapted to occupy a posit-ion above the top of the base rim. The oil pot pocket plate 6 has at its upper end an upturned and outturned flange 7, and is provided at its lower end with an annular bead (3 that is adapted to occupy a position beneath the top of the base rim 1*, while the upturi'ied and outturned flange of said oil pot pocket plate projects upwardly above the top of the base rim and into the lower end or inturned flange of the guard hoop. In this construction the annular head of the oil pot pocket plate serves to restrict said oil pot pocket plate from upward movement in the base rim, and the parts are united when pressure is applied to them, due to the upturned and outturned flange of the oil pot pocket plate being pressed outwardly and downwardly with the result of causing the inturned flange at the lower end of the guard hoop to be clamped between the upturned and outturned flange of the oil pot pocket plate and the top of the base rim 1 as seen in Fig. VIII.

1. In a lantern, a base rim, a guard hoop having a flange for connection with said base rim, and an oil pot pocket plate; all of said parts being connected by an interengaging flange joint, substantially as set forth.

2. In a lantern, a base rim having a central circular aperture, a guard hoop fitting in the central circular aperture in said base rim and provided with a flange, and an oil pot pocket plate having a flange fitted to the flange of said guard hoop and having an interengaging flange joint connection therewith, substantially as set forth.

8. In a lantern, a base rim having a central circular aperture, a guard hoop fitting in the central circular aperture in said base rim and having a bead above the central circular aperture, and a flange beneath the central circular aperture, and an oil pot pocket plate having a flange provided with an interengaging flange joint connection to the flange of said guard hoop, substantially as set forth.
