BAG.

SPECIFICATION forming part of Letters Patent N o. 533,174, dated. January 29, 1895.

Application filed April 13, 1893.

.To @ZZ whom t may concern:

Be it known that I, HANS JoHANsnN, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Mail-Bags; and I do hereby declare that the following is a full, clear, and exact description thereof, refer-ence being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in mail bags and it has for its object toprovide improved means for closing and locking the open ends or mouths of such bags.

The invention consists in the features of construction hereinafter set forth and claimed.

In the accompanying drawings a mail bag embodying this invention is fully illustrated.

Figure l is a side view of the upper part of a mail bag embodying the invention, the bag beingclosed and locked.- Fig. 2 is a top View of the bag,- also when closed, shown partly in plan View and partly in horizontal section. Fig. 3 is a top plan view of the bag, showing it open. Figs. tand 5 are partial' vertical sectional views through the parts formingthe mouth of the bag, the bag. being closed, said views illustrating alternative methods of construction. Figs. 6, 7 and S'are details of the locking mechanism. Figs. 9 and l0 are views showing in detail the method of constructing theyframe plates.

As shown in the drawings, A, represents the body of a mail bag, which maybe made of any suitable material and of any approved construction.

To the top margin ofthe body of the bag are secured four frame pieces or bars, B, B', B2 and B2, in any suitable manner, as by rivets, b.

rIhe adjacent ends of adjacent frame pieces are connected by means of hinges, O, C', C2, C3, so as to form a frame extending completely` around the top or mouth of the bag, and which is adapted to form a four-sided ligure,when the bag is open, as shown in Fig. 3. The relative length of said frame pieces is such that the combined length of two of said frame-pieces, as of B andB, will be equal to the combined length of the other two opposite frame pieces B2 and B3; thus` rendering it possible to close and lock said bag by foldingtogether the pairs of adjacent frame pieces B B2 and B B2, so as to bring the frame pieces B B3 in alignment with the frame pieces B B2 in the manner shown in Figs. 1 and 2. Preferably, these frame-pieces will not all be equal in length, but Will be made in sets, comprising a long frame-piece and a short fono; the frame-pieces forming opposite sides of the quadrangle formed when the bag is 4 open, being, preferably, of the same length.

The object of constructing the frame in this manner is to enable the frame-pieces, when opened, to form a rectangular figure, ofgreater length than width, to correspondwith the `shape of the racks or supports upon which mail bags ofthe kinds heretofore commonly used, are hung for distributing mail matter therein.

Theopposite frame-pieces, B and B2, have lianges, b and b2, at their upper edges, which flanges are madeintegral with the frame plates on which they are formed and the inner sides thereof are adapted to lit snugly over the exposed upper edges of the frame pieces B and B3 when thefb'ag is closed, thus securing close joints between the parts to prevent access of water or moisture to the bag when closed.

. The construction of these frame-pieces are important features of the p resent invention and will now b e described.`

. All of the frame pieces B, B B2, and B3 are compound in structure, consisting of suitable shaped bars or masses ofsoft vulcanized rubber, in which are embedded sheet metal strips, B4, of suitable size and thickness to give desired stiffness and strength to said pieces. The metal strip in the flanged frame pieces will be flanged to correspond with the external form of the same, so as to give proper form and support thereto.

As a further improvement the strips B4 are perforated or apertured throughout, as clearly seen in Figs. 4 and 5.

forating the strips is to allow the formation, in casting, of pieces b3, formed integral with the parts of the rubber sheathing on opposite sides of said strips so as to form a structure of which the parts are closely bound together The object of so perand in which the rubber sheathing cannot be separated from the inclosed sheet metal strips by rough handling or continued wear.

To afford the desired stiffness, without undue weight, these sheet metal strips B4 are made of metal which is corrugated longitudinally, as shown in Figs. 4t and 9. This construction makes the frame-pieces of ample strength and stiffness, while they may at the same time be economically and easily manufactured.

The hinges C and C2 are so constructed as to allow the frame-pieces connected thereby to be closed or folded together or parallel with each other; the pivots c c connecting the leaves of said hinges being for the purpose located approximately in alignment with the inner faces of the frame-pieces to which they are attached. In the case of the intermediate hinges C and C3, the pivots c c thereof are arranged near the outer line of the framepieces so that they will not interfere with the closing together of the ends of the framepieces,abutting shoulders c2 czbeing provided outside of the said pivots in position to come in contact with each other and arrest further iexure of the frame-pieces when they Aare straightened out, or brought into alignment with each other in closing the bag. Said shoulders obviously serve to give stiffness or rigidity to the frame as a whole, when the frame-pieces are closed together and the bag is locked.

For the purpose of affording room for the folds of the bag, where the latter is attached to the frame-pieces adjacent to the hinges C C2, the latter are provided at the inner faces of their parts or leaves adjacent to their pivots, with vertical recesses c3 c3 extending to the lower edges of the said leaves. The presence of these recesses gives room for a wide or rounded bend or fold in the bag when the bag is closed, thereby avoiding a sharp bend or crease, which would tend to injure the cloth o r leather forming the bag, while at the saine time insuring the proper folding together of the frame-pieces, notwithstanding the presence of a surplus quantity of leather or cloth. adjacent to the joint, which, in the absence of any such recesses to receive it, would become jammed between the frame-pieces and prevent the same from closing. The recesses c3 c3 are located outside of or beyond the ends of the frame-pieces to which the hinges are attached, the spaces thus afforded at the ends of the frame-pieces being utilized for said recesses. The hinges C and C3 are also shown as provided with similar but sliallower recesses c4 c4 to give additional room for the folds of the bag adjacent thereto when the bag is opened, but these are not essential inasmuch as the folds at this place will not interfere materially with the flexing of the hinges.

.The hinges may be attached to the framepieces in any manner found convenient or desirable, but as herein shown, the leaves or parts of the several hinges are formed by parallel inner and outer integral plates c5 c which are adapted to receive between them the ends of the frame-pieces, the leaves being secured to the frame pieces by rivets passing through both plates of each leaf and the intermediate metal strips and'inclosing rubber of the compound frame-pieces.

For the purpose of protecting the rubber of the frame pieces, and to give additional strength to the frame, the end hinges C C2 are desirably provided with flanges c7 c7 extending over the upper surfaces of the framepieces to which said hinges are secured. One of the intermediate hinges C is shown without any such flange but that part ofthe hinge, C3, attached to the flanged frame-piece B2 is desirably provided with a llange c8 extending entirely across or over the top surface of the iiange of said frame-piece. This flange ,cs thus arranged, is conveniently used for giving support to parts of a locking device hereinafter described.

Locking devices for holding closed the mouth of the bag are made as follows: Through the iiange e8 of the hinge C is formed a hole, o9, in Vertical alignment with a second hole cw, in a lug, C4, cast integral with the inner surface of the side plate of the hinge. Into these holes is fitted a pivot or rock-shaft, D, to the inner end of which is secured a hooked detent, d, which extends inwardly from the inner face of the frame-pieces to which the hinge is attached and is adapted to engage a hook, d', formed on a plate, D', rigidly attached to the frame-piece B. The detent d is held normally in position for engagement with the hook d by means of a coiled spring, E, attached at one end to the rock-shaft D, and at its other end to the lug C4 in which the main shaft is mounted. A lug or rearward extension, d2, formed on the detent CZ is adapted to strike the inner surface of the hinge plate and thus prevent the spring from rotating the said detent so far as to prevent its engagement with the hook d'. The portions of the detent CZ and hook d which strikes each other when the bag is closed are curved or beveled (Fig. 2.) so that as said surfaces come into contact with each other, the detent d will be forced back against the action of the spring, E, until the detent passes the end of the hook, at which time the spring will cause the engagement of the detent and hook and lock the bag.

The outer end of the rock-shaft D projects above the outer surface of the frame-piece, and an actuating lever, D2, is secured thereto by means of which the detent d may be disengaged from the hook'd in unlocking the bag.

Rigidlysecured to the frame-piece, preferably by attachment to the iiange of the hinge through which the rock shaft D passes, is a staple, F. This staple is so situated relatively to the rock-shaft and the actuating lever D2as not to interfere with the movement of said act- IOO IIO

uatinglever, incident to the opening and closing of the bag, while at the saine time allowing the shacklef of a padlock G to be inserted therein, when the bag is closed, so as to prevent movement of the actuating lever necessary to disengage the hooks. Thus the bag having been closed and the detent engaged with the hook and a padlock fastened in said staple, the bag will be locked.

Preferably, and as shown in the drawings,

vthe ends of the staple and the rock-shaft will be in alignment, the pivot being nearer one side of the staple than the other, so that the actuating lever may swing through the space between the ends of said staple. In its normal yposition also, which is substantially that which it will occupy when the bag is closed and the hooks are in engagement, the actuatinglever will extend obliquely through the opening of the staple, in such position that the shackle of a padlock secured to said staple will come between one side of the staple and saidactuating lever and will prevent movement of said actuating lever in a direction tending to disengage the hooks.

As shown in Figs. 5 and l0, the metal strips B4 are made of flat or sheet metal without corrugations. While thisconstruction is a practical one, that shown in the other figures of the drawings in which said strips are longitudinally corrugated, is preferred for reasons heretofore stated.

While the parts of the locking mechanism are shown as mounted on one of the hinge plates yet this construction is obviously not essential inasmuch as supporting plates or bearings for the locking device may be secured in any desired manner to the framepieces. As, for instance, the part herein called the iiange csmay consist of a plate separate from the hingeinstead of being integral with one of the parts or leaves thereof.
