CHARLIE LJLITCHELL, OF CHICAGO, ILLINOIS, ASSIGNOR, BY MESNE ASSIGN- MENTS, TO JAMES H. RAYMOND, TRUSTEE, OF SAME PLACE.

LANTERN-FRAME.

SPECIFICATION forming part of Letters Patent No.'394=,590, dated December 18, 1888.

Application filed June 9, 1888. Serial No. 276,574. (No model.)

To all whom it may concern:

Be it known that I, (HARLIE l. MITCHELL,-

of Chicago, in the county of (ook and State of Illinois, have invented certain new and useful Improvements in, Lantern-Frames, of

which the following is a specification.

My invention relates to lanterns having their frames or globe-guards made with vertical ribs of rectangular cross-section placed edgewise to the flame or burner, two of said ribs havin lugs projecting therefrom to which the bail is attached.

My invention consists in the parts and combinations hereinafter described and claimet'l.

In the accompanying drawings, Figure 1 shows a complete lantern in which my invention is embodied. Figs. 2 and 3 are views of two ribsdetached. Fig. l is a sectional view of one of the lugs to which the lantern bail is attached.

By reference to Fig. 1 it will be seen that the lantern-frame, globeguard, or basket, as it is technically termed, is composed of the vertical ribs C C &c., through which pass the circular wire ribs D Dtwo or more in number. To the uppermost rib, D, is hinged the lz'Lntern-top B. Two of the rectangular ribs, C have lugs c 0' formed on their upper ends, which lugs have holes g g, Figs. 2

and 3, for the reception of the ends of the lantern-bail E. By preference, I make the holes g g elongated in a vertical direction. The lugs c 0' receive a quarter-twist between their upper ends and their point of junction with the ribs, this being done for two purposes. One is to strengthen the lugs at the line marked 1 .r, where it was found in practice they were liable to bend sidewise, even when amply stiff everywhere else. The other purpose is to make the bail stay upright when wanted, though easily turned down, if desired. This is accomplished by twisting the lugs c c, so as to make them parallel, or, rather, so as to make their intersection with a horizontal plane parallel, for I may make their upper ends slightly diverging, as seen from the side,

as shown. As shown, the bail is made so that its ends are normally farther apart than the distance between the lugs, so that when inserted in the lugs it has a tendency to spring. Owing to the elongation of the holes g g or the divergence of the lugs, or both, it can expand most fully when in an upright position,

as will be readily understood from an inspection of Fig. 4, in which the dotted lines show the position of the bail when the hole g is circular, or when the bail is at right angles to the longer axis of the slotted hole g. The spring of the bail will thus tend to keep it uprightordinarily the most convenient posit-ion. It is obvious that the normal distance of the ends of the bail E might be less than that of the lugs e r, the operation being the same so long as the bail is in a state of tension or s n-ling" when in the lugs.

I am aware that. lanterns have been heretofore consl rucled having vertical guard-ribs of rectangular section placed edgewise to the flame, on which ribs are formed ears or lugs for the reception of the lantern-bail, and I therefore do not claim such a construction, broadly.

I claim 1. The combination, in a lantern frame or basket, of vertical ribs of rectangular section placed edgewise to the frame, circular wire ribs passing through the same, and lugs c c, projecting from said vertical" ribs and having a (p1arter-twist between their upper ends and their junction with said ribs, as and for the purpose set forth.

2. The combination, in a lantern frame or basket, of vertical ribs of rectangular section placed edgewise to the frame, circular wire ribs passing through the same, lugs c 0, pro jecting from said vertical ribs, having a quarter-twist between their upper ends and their junction with the vertical ribs, and having vertically-elongated holes g g, and bail E, sprung into said holes, as and for the purpose set forth.

CHARLIE I. MITCHELL.
