UNITED STATES 'PATENT OFFICEo 'JOHN R. OLINGER, OF CHICAGO, ILLINOIS.

LuNc'H-Box.

SPECIFICATION forming' part of Letters- Patent No. 279,662, dated June 19, 1883.

Application filed November 20, 1882. (Model.)

To ZZ whom it nuty concern: Be it known that I, JOHN R. OLINGER, `o Chicago, in the county of Cook and State of Illinoishave invented certain new-and useful Improvements in Lunch-Boxes, of which the following, in connection with the accompanying drawings, is a specification.

In the drawings, Figure lis a perspective representation of a lunch-box embodying my invention, showing the same unfolded or ready Fig. '2 is a perspective view of the frame. Fig. 3 is a like representation of the same when folded. Fig. 4 is a Vertical central longitudinal section of the folded box. Fig. 5 is a' central` cross-section in the line m .r of Fig. 1; and Figs. 6, 7, and 8 are. like sectious, showing the change in the position of the several parts during the operation of folding or closing the box; and Fig. 9 i

is a Vertical longitudinal central section of the parts as shown in Fig. 7, but upon a some-, what smaller scale;

Like letters of reference indicate like parts.

There are several principal parts forming this box-the lid A, the wire frame B, the sides O and D, the ends E and F, the bottom G, Vand the linked piece H. The lid A, the sides C and D, and the ends E and F are all hingcd to the frame B, the sides and ends depending therefrom when the box'is open or ready to receive its contents, and the lid being hingedthereto at one end, so that it may be 'folded over or laid upon the upper edges of ranged Vertically, there'by preventing the side.

- pieces from being swung outwardly after they have been brought to a verti cal position. The bottom G is hingcd to the lower edge of the 'side piece D, and its opposite edge is turned upward and then downward slightly, as shown at b, and the lower edge of the side piece C is turned inward and upward, as shown at c, to receive the depending tongue or lip on the free edge of the bottom piece, G, thus preventing' the part G from being swung down below a horizontal position or below the lowea' edges of the sides and ends of the box when the box is opened for use. `'In length and width the bottom piece, G, is such that it will be inclosed between the sides and ends of the open box.

The piece H is hingcd at its outer ends to the lower edges of the ends E and F, and is jointed at its center, as shown at (1,01' iu any suitable 'way It wi]] be observed that the piece H is `not so wide as the bottom piece, G.

I is a small catch to prevent the bottom piece, G, and the side piece to which it is hingcd from being swung up too far when the box is being lfolded' np, as will hereinafter more fully appear' Any suitable catch device may be employed for retaining the cover temporaril y in its closed position and looking the parts together temporarily when folded; or such a catch device may be omitted altogeth er without m aterially affecting the principal objects of my invention. I will now proceed, however, to describe the catch device which I have-shown. I

K is a rectangularly-bent strip of sheet metal, hingcd to that end of the frame B opposite that to which the cover 01' lid A is hingcd, and e is a slot in the part K. i

L is a small tubular piece applied to the free end of the lid A, and arranged to enter the slot e when the piece K is turned up over the cover, as shown in Fig. 1. The cover will thus be held closed with sufticient certainty under ordinary V('.ircnmstances5 but to lock the cover in its closed position I hi nge to the part K the bentwire K', adapted to slide back .and forth laterally in the part K, and so formed 'thatone'arm of the said wire will then move in and out of the eylindrical piece L, thus locking the cover in its closed position while the wire K' is in the said tube or cylinder.

M is a hooklshaped piece hingcd to thewire K', and the purpose of this hook will be hereinafter explained. N is a handle.

In order to fol d this box in the compact manner representcd in Figs. 2 and3, I unlock the lid or cover A and throw it back, and then push up the bottom piece, G, as indicated in ICO
