papers relating to certain persons or mattersv in a filing case lor drawer.

The object of the invention is to strengthen or stiffen such a folder at the point where the identification name or symbol of theA file is applied, Without increasing the weight or thickness of the file as a whole in the least, thereby enabling a folder to be made as a whole of relatively light and thin stock,

While being at the4 same time greatly strengthened at the portion Where the name or symbol occurs and Where the folder is most frequently grasped and handled.

Another object is to make the edge of the folder or file which is subjected to handling rounded and smooth, merging gradually with the faces of the stock on a continuous curve, instead of presenting raw edges and sharp corners.

In the accompanying drawings I have illustrated various forms in which the invention may be embodied, these forms all having the same essential principle.

Figure l represents one form of the file or folder in which the reinforcement is made by folding over theedge of the back of the folder and pasting down the flap thus formed against the back. Fig. 2 represents a third form in which the back of the folder is reinforced at its edge in the manner shownin Fig. l, and is cut to provide a tab. Fig. 3 represents a fourth form in which the back of the folder is reinforced only at the tab. Fig. 4 represents the blank from which the form shownin Fi 3 is made.

The same reference characters indicate the same parts in all the figures.

nThe article to which the invention relates is the folder or file commonly used in business to preserve all the papers relating to certain particular matters togethen Such folders are generallymade of material -havingthe necessary qualities of toughness and stiffness, such as Manilapaper.Y The folder as a whole is represented byia and the back or rear leaf thereof by 6.! 'This back is longer or higher than the front leaf either throughout its entire width, or for a limited extent. The projecting part of the back is adapted to bear the name of the person or of the matters to which the contents of the file relate. This part of the folder is subjected to a much greater amount of handling than any other part, particularly in the course of searching through a cabinet for any particular lfile tucked between others, and it is the purpose of this invention to reinforce such part locally. In the form shown in Fig. 1 this reinforcementis made by providing the back of the folder with a flap c Which is doubled against the back and pasted down. The vertical extent of the Hap is relatively slight as compared. to the entire height of the file, and preferably is such that when thefile is empty and closed the front 'leaf Will not overlap it, whereby it does not increase the lthickness of the le in the slightest. Thus the file is given more than double strength in the part where strength is most needed, without requiring the use of heavy stock.

In Fig. 2 the back Z1 is provided with a tab d', which is reinforced by a flap e. The latter ismade in one piece with the back,

and is doubled over against the same and.

pasted. The dotted line f represents the original line of fold. After the flap is thus secured the folded edge of the back is cut away, as represented in full lines in Fig. 2, leaving only the tab to project above the front leaf, this tab and the entire upper portion of the back being, however, strengthened and reinforced by the flap.

In Fig. 3 the folder is provided with reinforcement only at and adjacent to the tab. Here the reinforcement consists of a flap' g, which, when the blank for the folder is cut, extends beyond a tab 7L.' vWhen the tab is folded over upon the dotted line z' shown in Fig. 4, a reinforced tab integral with the folder back, and having an integral reinforcement, is made, as shown in Fig. 3.

In each embodiment of the invention the 'reinforcement is Wholly above either the twice as heavy andbulky stock, but occupying only 'half the space. From a practical thing desired. For instance, the symbol' may be stampedor marked directly 4on the Atabor edge,-as shown in Fig. l, lor it may l be made on a label pasted thereto, 4or it may vthe stock of which. the file is formed.

be applied v on the surface of the `folder back, as. 'shown in Figs. 2 and 3, being made visible through an opening 7c left in the reinforcing flap.

It will be noted that whether the entire `upper edge of the. folderback, as 'shown in Fig. l, or the upper edge of the tab, as shown in Figs.-2, 8 and 4, is made by folding over a part of the stock, such edge is smooth and rounded, merging with the front and rear surfaces of the folder back on a smooth curvature instead of being' divided therefrom by sharp corners. Thus such edge, which is the part subjected to handling 4when't-he files are being vlooked over in Xa case, is protected in the fullest possible manner againstwear. It is obvious that where the backedge is cut and so presents a raw edge, the wear is greater than when the edge is rounded by folding over a part pf l t the same time the thickness of the file is not increased. The part of the back edge which is folded over is made to adhere permanently to the folder back, as previously mentioned, hencethe edge to Which attention has just been called is not subjected to back and forth bending with consequent liability of breaking and'tearing, such as would be the case if the folded-over part or flap Were not thus permanently and adherently united to the back of the file.

I claim,-- l. A file wrapper or folderhaving a back,

' an'integral edge portion of such back being folded flat against the back, whereby a transversely roundedeXtreme edge of double thickness is provided, the'entire foldededge portion being adherently secured to the said back, whereby the saidv wrapper or folder 'is' not onlypermanently reinforced, but lthe rounded formy of the eXtreme edge is maintained, and the front being shorter than the back to such an extent that its upper edge may lie .beneath the bottom of the foldedv over portion whenthe folder is empty and closed, whereby to make the folder of uniform thickness vfrom top edge to bottom.

2. A file Wrapper -or folder having a front and a back, and a iap integral with the upper edge of the back folded flat against the back and pasted'thereto, the front being shorter than thel distance between the lower edge of the flap andthe bottom of thefolder, whereby to llie under the flap Y pasted thereto, said Hap having an apers ture through which a name or other indi' cation applied to the baclrmay be seen.

4. A file wrapper or folder including front and back leaves, the back leaf having a proj ectingf tab formed integrally with the back and reinforced by an integral extension of the back doubled over at the top edge of the tab and pasted to the back.

5. A Wrapper or folder having a back, an integral extension of such back. being folded against the back and permanently secured thereto by an adhesive, a part'of the upp'er folded edge of the back being cut away and leaving aI projecting tab, the outer edge portion of which is transversely rounded, and the Itab being thereby formed integral' with the back and of double thick-
