IMPROVEMENT l LANTERNS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern Be it known that 1, T. B. BURGERT, of Crestline, in the county of Crawford, and State of Ohio, have invented certain new and useful Improvements in Lanterns; and I do hereby declare that the followingv is a full and lcomplete description of the same, reference being had to the accompanying drawings, making part of this specilication, in which- Figure 1 is a side view of the lantern.

Figure 2, a detached section.

Y Like letters of reference refer to like parts in the different views.

This invention consists in a new and peculiar manner of connecting or securing the top or cap of said lantern to the body of the same, whereby the said cap can be removed with greater ease and facility than if connected to the body in the ordin'nry way.

This invention also relates to a peculiar device for adjusting the top or cap of the lantern to globes of different heights, hereinafter more fully described.

In g. l, A shows the bottom or lamp section of the lantern, to which the frame, or guard Bis attached, and whereby the rim O is supported, an under-side view of which is shown in g. 2.

To said,rim is connected the top, or cap Il), as fol- In the edge of said rim are cut two notches, a, g.

2. To the under side of the flange, or collar E, projecting from the base of the cap, are secured a pairof lugs, or ear's, b, the relative position of which to the notches a, in the edge of the rim, referred to, is such that on adjustingthe cap, so as to bring said lugs to the notches, as indicated by the dotted lines c, g. 1,

they will pass through them, thereby allowing the collar to flt down close upon the rim, as shown in fig. 1.

Now, ou turning thelcap in the direction of the arrows, the lip e of the lug, or ear will be drawn under the edge of the rim, whereby it is held firmly thereto.

. In order toprevent the ears from escaping from their connection to the rim, the cap is turned until the ear is caught by the spring f, in the hook of which the ear is retained, thereby preventing the cap from being turned in either direction.

By this means the cap is not only closely secured to the rim, but is prevented from being detached by swinging about the lantern, while in the act o'f carryin it or while giving signals.

he upper part of the l globe F is held in place by means of an adjustable removable cap, G, in the rim H of which the edge of the mouth of the globe ts,' and thereby held in proper relation to the top.

Said c'ap is maintained within the top by the resilient motion of the frill h, fg. 2, also indicated by the dotted lines fi, fig. 1, surrounding the inside of the top as a lining. Said frill consists of a series of metallic fingers, the base of which is secured to the side of the top, whereas the opposite ends are free.

1t will be obvious, that by this device lthe inward pressure of the fingers will clamp tightly the cap, which may be adjusted upward or downward, as the .length or height of the globe shall make it necessary. Hence globes of unequal height can be used in this lantern, should it be expedient in consequence of accident to a globe, rendering it necessary to replace it with another of a slightly different height.

It will be observed that the bail I is not attached directly to the rim, nor to the top 'of the lantern, but is pivoted to the frame, or guard B, which is not the case with lanterns as`ordinarily made. In such the bail is connected directly to the top, the result of vwhich is, that on swinging the lantern, while carrying or signalling with it, the strain consequent of such motion sometimes causes the top to become detached from the body, breaking the lantern, and-endangering those having itin use.

To avoidthis, the bail is attached to the frame at the points n, instead of to the top. 'Hence there is no possibility of the top becoming detached from the body of the lantern in consequence of swinging it about for signalling, &c.

Another' objection to having the ears whereby the bail is connected to the lantern attached to the top is, that the ears are usuallysoldered on, and, in consequenee of the heat, the solder softens, andscmetimes melts, so that the bail comes o', which cannot happen when said bail is attached to the lantern in the manner as herein shown.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination of the ears b, notches c, and spring f, with the top D, and rim O, when constructed to operate in the manner and for the purpose substantially as described.

2. The spring frill h, and removable cap G, in combination with the top D, when constructed to` be applied and to operate in the manner substantially as described.

T. B. BURGERT.
