2 Claims.

My invention relates to tab inserts for angular Celluloid tabs on guide cards and folders used in filing devices. In the more modern card index systems the guide cards are provided with Celluloid or metal tabs formed to take insertable labels or inserts, instead of the old fashioned extensions of the card material itself above the line of the tops of the cards. These tabs are made of triangular cross section, as well as flat, so that the portion facing the user of the index is angularlyV disposed for easier visibility. The Celluloid or metal tabs are made in varying colors as an aid to classification, and are provided with cardboard inserts, upon which appropriate indicia may be written, typed, or printed.

In the past these inserts or labels have been of a single strip or the double fold type, where the insert was `divided longitudinally into two portions, one of which bore the indicia and was disposed in the front portion of the tab, and the other of ywhich extended rearwardly in order to increase the frictional engagement of the insert with the tab. These inserts have been unsatisfactory in many cases, because they readily jar loose. Furthermore, in certain forms of guide cards or folders, the tabs are riveted on the card or folder, and no part of the card runs up into the tab, so that the single strip or double fold type of insert would t too loosely from the start. j

rWith the .above diiiculties in mind, it isgen- 1 erally the object of my invention to provide a tab insert which will fit any type of triangular tab, and which will not readily slide out of position, and to provide such a tab'which will be simple and cheap to manufacture.

This and other objects of my invention which will be pointed out hereinafter or will be apparent to one skilled in the art upon reading these specications, I accomplish by that certain construction and arrangement of parts of which I shall now describe a preferred embodiment. Reference is now made to the drawing which forms a part hereof, and in which Fig. 1 is a front elevation of a form of folder y having an angular tab, riveted to it.

Fig. 5 is a cross sectional view of the same taken on the line 5-5 of Fig. 4.

Fig. 6 is an elevational view of a strip of my novel tab inserts as it will be sold to the trade.

I have shown my invention in connection with 5 a folder and in connection with a guide card, and I have illustrated two diiferent forms of construction in connection therewith. It is of course understood that the forms of tabs may be reversed, and that a folder may have a tab as shown 10 in Figs. 4 and 5, and vice versa.

I have shown in Fig. 1 a type of folder I, having an angular tab indicated generally at 2, which is riveted to the folder as at 3. The tab has. the rear portion 4 which is parallel to the 15 rear wall of the folder, an inclined forward portion 5 through which the indicia on the insert may be read, a reversely bent portion 6, and a forward flat portion 1 which is parallel to the folder.

In the guide card shown in Figs. 4 and 5, the card I5 has a portion Ia which extends up into the tab member 2, and the portions 4 and 'I of the tab are cemented thereto, the rivets 3 being omitted.

The inserts, as shown in Fig. 6, may be provided in the form of long strips I0, divided transveresly by the score lines I2 into insert members II. The insert members II are themselves dvided into three portions IIa, IIb, and IIc, by 30 means of the score lines I3. The portion IIa is slightly wider than the others, and is the portion which will carry the indicia which will be visible through the portion 5 of the tab. Such indicia are indicated generally at I4. The score lines I2 35 will be relatively weak so that the inserts may be readily separated for use, while the score lines I3 will be less weak so that they will be readily foldable but not tearable.

When it is desired to use an insert, one of 40 the members II will be torn from the strip I0, and folded to the shape best seen in Fig. 3. It may then be inserted longitudinally into the tab. In the type of tab shown in Figs. 1 to 3 y inclusive, the portion IIa of the insert will bear 4 against the portion 5 of the tab, while the portion IIc of the insert will bear against the rear portion 4 of the tab, so that frictional engagement of two surfaces of the tab is provided for.

In the case of the type of tab shown in Figs. 4 and 5, there is less room inside the tab by virtue of the fact that the portion Ia of the card extends up into the tab, so that even greater fric-- tion is provided. The portions IIb and IIc of 5E the insert will occupy positions as shown in Figs. 4 and 5.

It will thus be seen that I have provided a simple and novel tab insert, which will hold equally well in either form of tab. It is to be understood that modications of my invention may be made without departing from the spirit thereof, and that my invention is equally well adapted to guide cards or folders having eitherform of tab. I therefore, Ido not intend to limit myself otherwise than as specifically set forth in the claims which follow.

Having noviT fully described my invention, 'what Y ying frictionally retained being of a Width to snugly fit the adjacent por= tion of said tab, and another portion being of less Width than its correspondingy portion of said tab and serving to bear against said corresponding portion of said tab in frictional engagement. 2. In a filing system, in combination with a ling element having a triangular tab, a tab insert comprising a strip of cardboard having three portions articulated together, one of said portions being of a width to ysnugly t the adjacent portion of said tab, another portion being of less width than its corresponding portion of said tab, and another portion intermediate said rstnamed portions being of a Width to snugly fit its corresponding portion 'of said tab, said insert be- Within said triangular tab.
