SCHOOL BAG AND BRIEF CASE Filed Feb. 24, 1930 Patented May 9, 1933 JACOB ROTH, or BROOKLYN, 'NEW YORK soHooL BAG AND BRIEF CASE Application filed February 24, 1 20. seria1no;.4so,7s4.

The present invention relates to school bags, brief cases and similar means for carrying books, papers and other objects, and itis especially advantageous when used for school bags. 1 One object of the invention is to provide a simple and inexpensive lining orstiffening member adapted to the interior of a school bag or similar device, for the purposev of forming a lining which will stiffen the bag and hold it in distended position to facilitate the placing of books, papers and other articles within the bag and removing them from it. Heretofore, school bags have been made not only of leather but of less expensive material such as imitation leather, and on account of the low price at which the same are sold, it is not practical to provide a stiffening frame of metal because 'ofthe-added cost of manufacture. On the other handflvhere no stiffening frame is "used, the bag is more or less flexible, easily loses itsshape, and it, is not convenient to place articles into and remove them from the bag. Under the )resent invention I provide :a liner, prefera ly made of inherently stiff material such as fibre board, which may.

be formed completely independently of the bag, and-of a-size to correspond with the interior of the bag when distended. This 30 liner or reinforcement may be inserted readily into the bag and ,then secured thereto by eyelets or any other inexpensive securing means. i V

The liner or reinforcement then becomes a permanent part of thebag and it serves .both to line the bagand to form a stiffer constructiom so .thatithebag will retain its shapein open or..distended condition. In additiomtheliningmember renders the bag I more durable. On theother hand, the lining member maybe made-one cuttingand creasing press ata very low cost so that the cost of manufacture of the bag with the im !proved lining member will bemuch less than iffa metal frame wereemployed to hold-the bag in shape. -Otheradvantages will beset forth in the following detailed description of my inventionu V I In the drawing forming .part of this application, a

Figure 2 is a sectional view taken on the line 2 2 of Figure 1, I y :5 Figure 3 is a face view of the blank from whichithe lining member is, made, and

Figure 1 is a perspective view of the lining member formed into shape, ready to be applied to the interior of the bag.

In the drawing I have shown my invention. embodied in a well known type of school bag, although it is to be understood that the same may be applied to brief cases and other carrying devices, the principal 16 difierence in these several articles being the quality of material of which they are made, size etc., so thata description of the-invention as applied to a school bag' will sufiice to teach the application of the invention to 11 other forms of carriers.

. In. the drawing Ihave shown a school bag of rectangular shape, the exterior or bag proper of whichconsistsof a front wall 1, a rear wall 2 spaced from and parallel to the front wall, and a strip 3 extending around the ends and bottom of the bag-and sewed respectively to the front and back walls 1, 2, as shown by the line (of stitches 4, ,to form the intermediate end ;walls and i1 he bottom of the bag, so that the bag, when in distended position, forms a'compartment ,5 to receive and hold books, papers and other obj ects;

For convenience I have illustrated the invention asapplied to a single pocket 2 bag, that is, a bag having one receiving compartment 5, as the invention is especially advantageous when used in connection-with this type of bag. There is a flap or covert formed by an extension of the back wall, 59 and preferably this is provided with a hem the edge thereof, although this forms no part of the present invention. I 'haveshown a patch compartment-on the front wall of the bag, composed 5 of a sheet ofumaterialv 8 stitched around three of its edges to the front :wall 1 to form, with the front wall, an outercompartment for holding smaller objects, such as pencils, erasers etc., and this is provided 1. 0

with a flap or cover 9 adapted to be secured in closed position by the strap and buckle 10. The exterior pocket may be used or not, as desired, as it forms no part of the present invention. I have shown one of the straps 11 with a suitable buckle 12 for securing one side of the flap or cover 6 in closed position, and it will be understood that a similar strap and buckle will be pro vided adjacent the opposite end of the flap or cover, but the same is not shown because the view is broken away in Figure 1.

In making the lining member, a blank 13 of inherently stiff material is formed, as shown in Figure 3, of cardboard or similar material, and for this purpose I prefer to use fibre board because of its inherently stiff and tough character. The blank is formed with the several score or crease lines 14: extending parallel with the several edges of the sheet and with longitudinal scoring or crease lines 15 extending between the lines 14 so that these several lines form three sides of two rectangles separated from each other by the intermediate section or member '16. In line with the score lines 15 I have provided four slots or cuts 17 extending inwardly from the opposite edges of the sheet and terminating in line with the end scorings 1 1. In forming the sheet into the lining member shown in Figure 4, it is bent on the several score lines 14:, so that the sections 18, 19 extend at right angles to the front and back walls 20, 21 of the lining member and overlap each other, as shown at 22 in Figure 4. The small tabs 23 in line with the section16 are preferably turned up at right angles to the latter and lie within the end walls. It will be understood also that the blank is bent on the score lines 15 so that the section 16 becomes the bottom member as shown in Figure t. There is thus formed a rectangular compartment 24' of the lining member having a front and back wall, end walls, and a bottom wall with an open top.

The flap or cover 6 of the bag is swung open and the lining member shown in Figure a'is inserted through the open top of the bag and forced downwardly until the bottom wall 16 of the lining member rests on the bottoniwall of the bag.

The lining member is then attached, preferably permanently, to the bag, so that it becomes an integral part thereof, and the attachin g means also serves to attach the overlapping members 18, 19 forming the end walls of the lining member to each other.

For this purpose .I have shown eyelets 25 passing respectively through the back wall 21 of the lining member and the back wall 2 of the bag, and these eyelets are'upset or jflattened to secure the back walls of both the lining member and the bag together. Preferably these eyelets are attached adjacent the upper portion of the lining member and the bag and the holes for the eyelets are preferably formed after the lining member has been inserted into the bag, so that there will be no difficulty in having the apertures register for the eyelets to be inserted. In like manner eyelets 26 are passed through the overlapping sections 18, 19 of'the end wall of the lining member, and through the end wall 3 of the bag, and then flattened or riveted. Preferably, the apertures for these eyelets are arranged adjacent the top of the lining member and bag and the apertures are preferably formed after thelining member has been inserted, to insure their registerthe front wall 1 of the bagto secure these,

together. lVhile I have described the se curing members as eyelets, it will be obvious that rivets, staples or other securing means may be employed if desired.

he lining member fits snugly against the front and back walls of the bag, as well as against the end and bottom walls thereof, and serves to hold the bag distended to its full size and it also stiffens the bag throughout, except for the flap or cover 6 which is advantageously left pliable.

The eyelets 26 which pass through the end sections of the lining member serve not only to unite these portions of the lining member to the end walls of the bag, but they also limit the overlapping of these sections" 18, 19 and therefore prevent the lining member from collapsing beyond the position shown in Figure 2. In other words, these eyelets I hold the lining member distended in the powalls to form a receptacle of the character described, and having an open top adapted to be closed by a flap formed on said bag and a separately formed lining member of relatively stiffer material than said bag member, said lining member having front and rear walls, a bottom wall and end walls,

said end walls consisting of overlapping sections, said lining memberbeing adapted to be inserted into the open end of said bag after the latter has been formed, to provide stiffening means for the several walls of said bag member, and means passing through 'the adjacent Walls of said lining member and said bag member to secure said walls together, some of said securing means passing through the overlapping end Walls of said lining member and the adjacent Walls of said bag member.
