Specification forming part of Letters Patent No. 56,567, dated July 24, 1866.

To all whom it may concern:

Be it known that I, EUGENE N. JENKINS, of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Lanterns; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure 1 is a perspective view with one quarter removed vertically; Fig. 2, a front view of the base with the guards and upper portion of the globe removed, also a vertical quarter; Fig. 3, a top view of the plate or disk E detached; Fig. 4, a front View of the base, similar to Fig. 2, showing a different plate or disk, and Fig. 6 a top view of the plate or disk E detached.

Like letters refer to similar parts in the several figures.

The nature and object of my invention consists in constructing the base of a lantern so the globe will be firmly supported by a band and disk or plate, which can be removed through the bottom of the lantern without detaching such band from the globe, so that the globe may be removed with safety whenever desired, and the strength of the lantern preserved in all of its parts, and in so constructing the base of the lantern that none of the parts can be displaced without breakage.

To enable others skilled in the art to make and use my invention, 1 willproceed to describe its construction and operation.

The cap or dome B of the lantern is constructed in any of the known forms and of any suitablematerial. Any of the known forms of globes A may also be used; but I prefer the cylindrical, conical, or oblate to the spherical, as they make the completed lantern in better proportions.

The broad or bottom part of the base 0 is made narrow, as shown, the figures being full size and the opening at the top a little larger than the largest diameter of the globe. The guard F is attached to this band, as shown at h, Fig. 1.

The band D is made to project above the top of the base 0 and fitted around the neck of the opening or mouth of the globe. To

this band D, I attach a disk or plate, E, which is either soldered or attached by a close-fitting joint, as shown at E, and fills the space between the band D and the base 0.

As the band D and the disk E support the globe and the oil-cup, it becomes necessary to give them a firm support on the base 0. This can be done in a variety of ways. In Fig. 1 they are supported by the springs a a, which are attached to D. By a slight change of form the springs may be attached to O. In the modification shown at Figs. 2 and 3 they are supported by the ledges or projections c, and kept in place by the horizontal spring (1. The disk E in this form is made of castiron and cut away so as to leave simply projections to make the connection between D and O, leaving open spaces between them for the passage of air.

In the modification shown at Figs. 4. and 6 the disk E is cut away at 6, so as to pass the ledges 0, when, by a slight or a considerable turn it is passed over them and securely held in place. In the form shown at Fig. 2 a slight turn is also necessary to secure the disk, and so much of it being cut away it is necessary to secure it from farther turning, which is done by the spring (I. In the form Fig. 1 no turning is required, as it will be firmly held whenever inserted.

The oilcup is held in place by springs resting upon the ledge f, and can be first withdrawn, or be withdrawn with the band and disk. When the springs are compressed, or the disk and band turned, the disk, band, and globe come down through the bottom, and, coming down with a natural motion and all attached together, there is less liability of breaking the globe than where the lantern is disconnected in several places or parts. This form also enables me to make the wick-ratchet project through the opening g with a short stem or shaft, as it materially contracts that part usually calledthe base at this point. The air-holes or perforations are also made in the band D, and are made above and below the disk F, so that whatever motion is given to the lantern a sufficient supply of air will be furnished.

It will be obvious that this makes a complete and cheap lantern, as there are but very few parts used in its construction, and these in the'simplest forms, and the connections such E, for supporting a lantern-globe, substanas to makeit safe and strong, and a decided tially as set forth.

Having thus fully described my lantern, EUGENE N. JENKINS.

What I claim as new, and desire to secure by Witnesses:
