Claims.

This invention relates to leather, canvas, or similar type bags, or cases, used in the carrying or transportation of money, securities, jewelry, etc., and especially to a metal mesh lining for 5 bags of the character described which will prevent cutting of the bag, or case, by a knife or like implement to remove the contents.

There are a variety of bags usually made of heavy leather which are used to carry or transport valuables of different character. Such bags are sometimes referred to as security bags, money bags, messenger bags, etc., and while they are equipped with an elaborate locking mechanism, often requiring the use of two keys to open them,

it has been found that the sides or bottom of the bags can readily be cut with a sharp knife or like implement and the contents removed.

The object of the present invention is generally to improve the construction and operation of bags or containers of the character described, and

particularly to provide a metal mesh lining fabricated from wire, steel strips, chain, or a like knife resisting material so as to provide a safeguard against slashing or cutting open the container to gain access thereto.

The invention is shown by way of illustration in the accompanying drawings, in which- Fig. 1 is a perspective view of the metal mesh lining particularly designed for insertion in bags of the so-called Boston type.

Fig. 2 is a central vertical cross section of a Boston bag showing the metal mesh reinforcement placed and secured therein.

Fig. 3 is a perspective view of the metal mesh 85 lining used in containers, such as brief cases, or

the like.

Fig. 4 is a plan view of the metal mesh or mat employed in forming the lining shown in Fig. 1.

Fig. 5 is a plan view of the metal mesh or mat 40 employed in forming the'liner as shown in Fig. 3.

Referring to the drawings in detail, and particularly Figs. 1 and 4, the numerals 2 and 3 indicate thin strips of flexible steel laid at right angles to each other. These strips are riveted, or

45 otherwise secured, with relation to each other at the points of intersection as indicated at 4. The steel strips thus form a metal mesh flat fabric which will hereinafter be termed a mat, and is generally indicated at A in Fig. 4. The mat, in

50 turn, will be bent, out and shaped to form what will be termed a basket and this is generally indicated at B in Fig. 1.

Again referring to Fig. 4, it will be noted that the upper edge of the mat is cut out at the points 55 indicated at 5 and 6.to permit free folding of the leather at each end of the bag. The cut ends are connected by chains 51: and 6a and by central chains 5b and 6b, the upper ends of which are riveted to the outside leather or attached to the pivotal points 1 and 8 of the main frame, which 5 is generally indicated at C, see Fig. 1. After the mat has been cut out and the chains attached,

it is necessary to bend the mat along the dotted lines indicated at 9, H), II and I2 to form one side I 3 of the basket, a pair of ends l4 and I5, and 10 the opposite side [6, said side being formed by overlapping or joining the free ends at the point I! and riveting or otherwise securing it. The, upper edges of the mat are then attached to the frame by loops of tuft wire l8, such as piano wire 15 or the like, and the lower free ends I 9 of the mat are bent inwardly to form the bottom of the basket, the overlying ends being riveted or secured by connecting wires or by being suitably fastened to a bottom steel plate such as shown at 20 in 20 Fig. 2. This completes the forming and assembling of the basket which is now inserted in the partially completed bag, the sides and bottom of which are indicated at 22 and 23 in Fig. 2. After insertion the bag is sewed or otherwise se- 25 cured to the main frame C, the lining is then inserted and secured and when the bag is completed the metal mesh becomes interposed between the outer leather or fabric of the bag and the lining and as such is completely concealed. 30.

The metal mesh lining does not detract from the general appearance of the bag but, conversely, rather improves it as the lining stifiens and reinforces the leather in the bag, thereby retaining its shape and preventing sagging, but more important it provides a knife resisting lining, the

virtues of which should be obvious.

The bag just described is of the type known as a Boston-bag. In that bag the only part of the leather that folds to any extent is the portion at each end below the pivotal parts of the main frame and it is for this reason that the upper ends of the steel strips forming the reinforcement at the ends of the bag are cut away and the chains 5a, 5b and 6a, 6b substituted, as such chains permit free flexing of the leather, or other material from which the bag is formed.

In other types of bags, for instance in brief cases, it is necessary to form the mats in a different shape and to fit the entire mat ends with chains in order to provide more flexibility for the so-called gusset ends of the brief case. In this assembly the mat is first formed in the flat, as shown in Fig. 5. It is then bent on the dotted lines indicated at 25 and 26 to bring the sides upwardly and to form a basket of substantially U-shaped form. This is clearly shown in Fig. 3, the sides being indicated at 21 and 28 and the bottom at 29. This basket is then secured to the main frame C by the wire loops in a manner similar to that shown in Fig. 1, and the ends are connected by cross chains, such as shown at 30. The basket when completed is finally inserted in the brief bag and this, together with the fabric lining, is sewed in place so that the metal mesh will become interposed between the same.

The invention so far illustrated has been more or less limited to bags, such as Boston bags, brief cases, and the like, obviously it may be inserted in suitcases, trunks, and other containers which are made of a material that might be cut by a knife or similar sharp implement. The drawings illustrate only one form of metal mesh, to-wit, steel strips riveted with relation to each other and chains connecting the same, but obviously a wire mesh; or similar metal fabric could be employed, and while other features of the invention are more or less specifically described and illustrated, I wish it understood that various changes may beresorted to within the scope of the appended claims. Similarly, that the materials and finish of the several parts employed may be such as the manufacturer may decide, or varying conditions or uses may demand.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:-

1. In a bag or like container having a pair of .pivotally connected frames to permit opening and closing of the container, 2. non-metallic-covering secured to the frame and forming the sides, ends and bottom of the container, said material being foldable at the upper portion of the ends to permit opening and closing of the frame, a flexible metallic mesh forming a lining for the sides and bottom of the container, and metal chains forming a liner for the ends of the bag and secured to the metal mesh.

. 2. In a bag or like container having a pair of pivotally connected frames to permit opening and closing of the container, a non-metallic covering secured to the frame and forming the sides, ends and bottom of the container, said material being foldable at the upper portion of the ends to permit opening and closing of the frame, a flexible metal mesh forming a lining for the sides and bottom and a portion of the ends of the container, and chains forming a lining at the upper foldable portions of the ends of the container.

3. A bag or like container having an exterior covering of flexible, non-metallic material and a lining of flexible metallic mesh material to prevent cutting to gain access to the interior of the container, said metallic mesh consisting of flat, narrow, thin steel strips disposed at right angles to each other and rigidly secured to each other at the points of intersection.

4. A bag or like container having a pair of pivotally connected frames to permit opening and closing of the container, a non-metallic covering secured to the frame and forming the sides, ends and bottom of the container, said material being foldable at the upper portion of the ends to permit opening and closing of the frame, a flexible metallic mesh forming a lining for said material to prevent cutting to gain access to the interior of the container, said metallic mesh consisting of flat, narrow, thin steel strips disposed at right angles to each other and secured at the points of intersection, the strips forming the ends of the bag extending up to the foldable portion only, and a plurality of metal chains extending crosswise of the foldable end portions of the bag and secured to the steel strips covering the sides of the bag.

5. In a bag or like container having a pair of pivotally connected frames to permit opening and closing of the container, a non-metallic covering secured to the frame and forming the sides, ends and bottom of the container, said material being foldable at the upper portion of the ends to permit opening and closing of the frame, a flexible metallic mesh forming a lining for the sides and bottom of the container, metal chains forming a liner for the ends of the bag and secured to the metal mesh, and means securing both the flexible metallic mesh and the chains to the pivotally connected frames.
