FILING AND NDEXING DEVICE Application led April 11,

This invention relates to filing and indexing devices generally of the type provided with a tab adapted to receive and display suitable indexing indications, and more particularly refers to tiling pockets or folders such as are generally used for filing correspondence or other papers in vertical filing and kindred systems This application is tiled in continuation in part of an abandoned application for Filing devices filed March 0 e, 192e, ser. No. 91,948.

0 said label may be displayed.

Another object of the invention is to provide a device of the character specified provided with a tab formed integral therewith,

adapted to receive, retain and display a removable label, said tab also being provided with a transparent label covering serving the double purpose of protecting the underlying label from soiling or defacement, and reinforcing the slotted portion of said tab.

A further object of the invention is to provide a tiling or indexing device of the character sjecified providedwith an index tab adapted to receive, retain and display a removable label, said tab being obtained by folding over a part of the material out of which the device is made, to form a labelreceiving` chamber, the edge of said foldedover portion being further bent inwardly to provide a thickness of material between the folded-over portion and the body of the device itself.

:l still further object is to provide in a device of the character specified a novel and improved type of tab having a chamber adapted to receive and retain a removable label, said tab being provided with a slot through which the indications carried by the label may be displayed, eXtending up to the `ipyer end of the tab in order to prevent bulging, tearing and wear which will otherwise 1928. Serial No. 269,218.

take place when the display slot is spaced a short dist-ance from the top edge' of the tab in devices made from comparatively light grades of paper stock. i

Other objects and advantages of the present invention will more fully appear as the description proceeds and will be set forth and claimed inthe appended claims. i

Filing and indexing devices provided with tabs adapted to receive, retain and display a movable label are not in a broad sense new. However, as a general rule'the tab or label holder is constituted by a separate piece of material which is folded over to form a chamber adapted to receive a label, and which is pasted or secured onto the body` of the device in any suitable manner. This mode of construction is frequently used for instance, in connection with guide cards such as generally used in vertical filing systems, Vsaid cards being usually made out of relatively heavy and stift' cardboard. Certain other types ot' tiling and indexing devices such as for instance ordinary tiling folders and loose leaf sheets, which are made of relatively ilexible and light material, are generally only provided with tabs projecting above or laterally of the body of the device providing a surface on which the desired indications may be written direct. Y

Handwriting however, is not'very satisfactory because it is not always very legible and neat in appearance, and therefore very frequently the desired indications are typewritten on a strip of paper' and this is' then pasted onto the tab. Both direct handwriting and a label thus pasted onto the tab however, provide indications of a permanentcharacter which cannot be erased and which can only be corrected by covering them with a new strip pasted on the top.

The use of pasted strips however is objec-V tionable in many respects; the pasting itself is a tedious and laborious task, and the results are generally not as neat as would be desirable. 0n the other hand these types of devices, especially iiling folders are us'edfin such large quantities that it would be commercially impractical to materially increase their cost of production by providing them Cil with removable label tabs of the ordinary type.

Furthermore it is of the utmost importance in devices of this kind, not to increase the thickness of the body of the device itself, because even if such increase should be practically negligible in so far as each individual folder is concerned, it would result in a material decrease in the tiling capacity of a filing cabinet containing a considerable number of folders.

By my present invention l provide a filing and indexing device of the character specified' which is formed with a tab adapted to receive and display a removable label entailing practically no additional cost for the production of the device.

Fig. 26 is a fragmentary side sectional view illustrating the top port-ion of said pocket.

ln Fig. 1 l illustrate the manner in which two filing folders of the type shown in Fig. 4 may be obtained from a single rectangular blank without waste of material. Referring to Figs. 2 and 4, it will be observed that 21 designates a filing folder comprising a rear flap 22 and a front flap 23 joined at the bottom by a folded edge 24. The rear flap is formed with a tab 25 upwardly projecting therefrom, comprising a rear member 26 eX- tending upwardly and in continuation of rear flap 22, and a front member 27 obtained by folding over said rear member 26 at the upper edge 37 of the tab, and pasting the edge portion 29 of said folded-over member onto the inner .nrface of rear flap 22.

By virtue of this construction the rear and front tab members 26, 27 form a retaining chamber through which an index label 30 can be inserted sidewise throughout the entire length of the tab. Said label may of course carry suitable indications which will show through an elongated slot 31 provided adjacent the upper edge of front tab member 27.

The front flap 23 of the folder is made lower in height than the rear flap, as is customary in this class of devices, and is in factmade of a height less than or equal to the distance separating lower edge 32 of front tab member 27 from the folding edge 24 of the folder; so that when the front and rear flaps are folded flat against cach other only two thicknesses of material result, the front flap being flush with the front tab member 27.

Two folders of the type just described can be conveniently obtained from a single blank 33 without wastage of material, as shown in to the width of the folder, and its total length being equal to twice the total length if the'.fr I

body portion of the folder when unfoldgv plus the distance separating the lower edge 32 of the front tab member 27 from the upper edge 34 of rear flap 22 when the tab is in its unfolding condition.

rlhe tab is preferably only half as wide as the body of the folder or less, and therefore two tabs can be obtained from a single width of blank., as Fig. 1 clearly shows.

lf 35 designates the upper edge of front flap 23 of the folder, 35 designates said edge in the blank of Fig. 1, and 35 designates the corresponding edge of the other folder obtained from the same blank; while 2l', 21 designate the folding edges of the two folders respectively. 34 designates the line delining the upper edge 34 of rear flap 22', said line also defining at the same time the lower edge 32 of the front tab member 27 of the other folder.

Said line 34 is at a distance from folding edge 21 corresponding to the height of the rear flap 22 or 22, and in a similar manner line 34-32 is at an equal distance from folding line 2l, of the other folder. By slitting now the material through lines 34, 34 from each edge to the center line of the blank, and then by slitting it along a longitudinal central tract 36 connecting tracts 34, 34, the blank will as a result be divided into two elementary blanks each of which will form a complete folder. Y

The distance separating line34 from line 34 in a longitudinal sense is equivalent to the extension of the tab when in its unfolded condition from the upper edge 34 or 34 of rear flap 22 or 22. If 37 designates the upper or folding edge of the tab, dotted lines 37, 37 in Fig. l designate the corresponding folding lines of the tabs extending' from blanks 21, 21". 3l', 3l designate the display slots, and

29', 29 designate the lower edge portions of the front members 27, 27 of the tabs, said edge portions vbeing shaded to indicate the fact that they are or will be covered with an adhesive substance in order to be pasted `against the inner surface of the rear flap of their respective folders as indicated by panel portions 33', 33".

The projections from which the tab portions are obtained are preferably cut with a rounded corner or fillet as shown at 39, 40

in order to produce a stronger connection between said tab portions and the body of the device. The resulting folder besides affordmg the main advantage of being adapted to receive a removable index label also represents an improvement over folders of the ordinary type in being reinforced by a double thickness of material at its tab portion, which is the part of the device most subject to 'han- -dling and wear.

Another advantage is that the back of the folder is perfectly smooth and there is no chance of its becoming entangled with other folders in the file. A still further advantage is the improved appearance of the article due to the use of the same material throughout. f

In order to protect the label from soiling or defacement I also prefer to use a transparent covering for the slot or window through which the index label is displayed.'

This can be done by pasting a transparentv panel as shown at 41 in Fig. 3 against the inner surface of the tab member through which the slot is cut directly behind the slot. Said transparent covering is preferably made to extend throughout the entire surface of the slotted tab member so as to form an ecientreinforcement thereby preventing bulging out or wear or deformation ofthe edges of the slot.

In Fig. 5 I illustrate a filing folder similar to that shown in Fig. 4, showing the possibility of using two eyelets 42, 43 instead of or besides the adhesive substance previously mentioned for securing the bent-over portion of the tab onto the body of the device. In said drawing I also illustrate the possibility of providing two or more slots 44, 45, separatlusually provided for by means of spaced tabs projecting sidewise of the guide sheets. The indexing indications proper may be directly printed on these sheets or else they may be written by hand, or typewritten, but once they are printed or written .they cannot be altered without defacing the sheet.

It is therefore preferable in many instances to provide means for indexing by means of removable labels, saine as explained in connection with the previous figures, and this may be done by forming the guide sheets such as shown at 47 in Fig. 6 with an extension which may be folded inwardly and pasted onto the sheet as shown at 43, leaving a passage between said portion and the unfolded portion of the projection through which a label may be inserted. Also in this case the tab thus formed may be provided with a window or slot 49 which may be reinforced if desired by the insertion of a transparent covering, or else the window may be altogether omitted if the Sheet itself is made of transparent material or if the material is made transparent at the point where the label must show.

The tab portions thus provided in each guide sheet may be properly spaced or staggered in relation to one another, so that the full set of labels may show when the guide sheets are placed in the loose leaf device in the usual systematic arrangement.

It is obvious that while the opening or slot in the various devices so far described is shown only at the front of the device. a

similar opening can be provided besides 'or Vthe window or opening may be omitted if the material out of which the folder or other device is made is itself transparent or the adapted to be made locally transparent by any suitable process.

The label-receiving chamber fo 'med in the manner previously described by folding free end of the extension out of which the tab is formed directly over `the remaining portion of said extension only permits the insertion of a label made of relatively thin stoel; due to the fact that the inner surfaces of the front and rear tab member are directly abutting against each other. In order to insert the label it is in fact necessary to press down the upper edge of the tab so as to spread its two members apart, and this may in time mar the appearance and strength of the tab itself.

In order to form a label-receiving chamber in which a label may be easily inserted and from which it may be removed with equal ease, I prefer to produce the tab by the method illustrated in Fig. 8, where designates the rear tab member and 5l designates the front tab member provided with a slot or opening 52. rIhe front tab meinber is made longer than that used in the arrangement of Fig. 2, and its free end portion is turned :inwardly as shown at 58 about the lower folding edge forming a thicliness of material between the rear and front tab member as shown.

The inwardly folded portion 53 is pasted against the inner surfaces of both the front and the rear tab members, or else the resulting three thicknesses of material are perjinanently bound together in any other suit- -terial out of which the device is made, and

the inner edge 55 of the folded-in portion 53 forms the lower surface of the labelreceiving chamber thus obtained. In this manner the label 56 can be easily inserted .j sidewise through the receiving chamber and `inst as easily removed therefrom, as will be understood.

In order to produce a folder of the same dimensions as that illustrated in Fig. fl, this construction of tab calls for a bla-nk which is somewhat longer than that shown in Fig. l, the added length being represented by the height of the folded-in portion 53. Such a blanl; is represented in in which 57,

' 5? are the front flaps of the two folders obtainable from said blank, 58, 58 are the rear flaps of the same, 59, 59 designate the two transversal tracts through which the blank is slit to produce the upper edges of said rear flaps, and 60 designates the center longitudinal tract connecting` said tracts 59, 59 through which the material is slit to produce the tab portions 6l, 5l.

Botted line 62 designates the upper folding edge of tab 6l and dotted line 62 similarly designates the upper folding edge of tab 6l. rIhe lower folding edge of the front member of tab 6l is designated by dotted line 63 while the lower folding edge of the front member of tab 6l is designated by dotted line 63.

Tracts 59, 59 also define the inner edges 55, 55 respectively of the folded-in portion of the front tab members, which are designated by numerals 53, 53 respectively. Adhesive material is spread over both surfaces of said folded-in portions 53, 53 so as to paste them against the corresponding shaded portions (5t-65, 64K-65 respectively, when the tab is formed asshown in Also in this case it is possible and preferable to reinforce the slotted portion of the tab and to protect the label inserted therein by providing a thickness or panel 66 of transparent material pasted against the inner surface of the front tab member, as shown in Fig. 9.

It will be observed that in all the devices so far described the front tab member is provided with a slot or opening which is spaced from the top of the tab a relatively small distance, forming a narrow tract of material extending for the length of the slot between the upper edge of said slot and the upper folding edge of the tab. In practice have found that when a device of this type 1s subjected to frequent handling said narrow tract of material soon becomes ragged, bulging outwardly at various points and eventually becoming torn or otherwise damaged. rIhis detracts from the appearance of the device f and entails the necessity ofy frequently renewing folders in order to keep a file in proper condition. I have therefore conceived the idea of improving the device by extending the slot up to the upper folding edge of the tab thus omitting entirely the narrow portion of material which is hanging over the slot in the device shown in Figs. 4;, 5, 6. In this manner there is no part of the tab which can become unsightly or damaged and an added advantage is furthermore obtained by producing a wider slot without increasing the height of the tab.

Such an arrangement is illustrated in Fig. 10 where 67 designates a folder of the type shown in Fig.' 5, where the two slots 68, 69 separated by the cross member 70, provided through the front member 71 of tab 72, eX- tend to the very folding edge 72 of the tab, as shown.

The same modification is shown in Fig. ll where 73 designates a folder of the type shown in Fig. 4, provided wit-h tab T4 which is provided with a slot 75 extending to the upper or folding edge 76 of the tab. The same modification is also shown applied to a loose leaf sheet in Fig. 12 where Z7 designates a loose leaf sheet similar to that of F ig. 6,

formed with a tabV portion 78 which is provided with a slot 79 extending to the folding edge 8O of the tab.

The tab portion can also in this case be formed either by directly pasting or securing the lower portion of the front tab member to the inner surface of the rear Hap, or else by folding said lower portion inwardly so as to form a wider label-rec-eiving chamber by interposing a thickness of material between the front and the rear members of the tab.

In Fig. 18 I illustrate a blank similar to thatof Fig. 1 except for the fact that the slots 75 are cut with their inner side along the folding edge 76, 7 6 of the tabs, in order to produce folders of the type illustrated in Fig. 11.

In Fig. 14 I illustrate another blank, corresponding to the blank of Fig. 7 where 81, 81 designate the two folded-in portions of the front tab members of the two folders obtained from said blank, and 82, 82 designate the slots the inner side of each of which also in this case is cut along the uppervfolding edge of the tab 83, 83.

. In Fig. 15 I illustrate the tab obtained by the arrangement of Fig. 13 where it is seen that the slot 75 extends up to the folding edge 76', so that only two smooth surfaces, that is the front surface of the index label and the rear surface of the rear tab member result, free from overhanging portions or edges; so that by holding the tab portion between the fingers in order to remove a folder from the file, no harm to the folder will result even if the same is subjected to frequent handling.

In Fig. 16 I illustrate the same arrangement with the addition of a transparent covering 84 as previously explained.

In Figs. 17, 18 I illustrate the tab obtainable by the arrangement of Fig. 14, in which the lower portion 81, 81 of the front tab member is folded inwardly as previously explained. Fig. 17 illustrates a tab where the label 85 is completely exposed, while Fig. 18 illustrates a similar arrangement where the label 86 is covered by reinforcing transparent covering 87. i

It will be understood that in this arrangement the label will be held in position by its two ends projecting beyond the slot; therefore it is preferable to make the label out of fairly stiff material such as for instance light cardboard.

It will also be observed that while it is preferable to provide a thickness of material such as shown at 58 in 8 and 81, 81 in Figs. 17, 18 by folding inwardly the lower edge portion of the tab front member, it is quite possible if desired to use a separate strip yof material for this purpose without departing from the scope of my invention.

My invention may also be applied to filing pockets of the open top type, as shown in Figs. 19, 20. In the same 88 designates an open-end filing pocket comprising a rear panel 89 and a front panel 90 joined by extensible bellows-like bottom 90 and sides 91, When the blank from which the pocket is obtained is cut the rear panel is formed with a projection shown in dotted lines-'at 93, which is substantially rectangular in shape or else is as shown rectangular with a tapered outer end.

At a certain distance from the upper edge 94 of the rear panel 89, said projection is provided with an elongated opening 95 which will remain above said edge 94 as shown at 95L when the outer portion of said projection is folded inwardly along the line 96coinciding with the lower edge ofopening 95 when the tab is in its extended position.

The portion 97 of the projection which extends within the pocket is pasted or otherwise secured to the rear panel 89, as previously described. In order to obtain a strong construction I prefer lto both paste the flap in position and to secure it therein by means of an eyelet 98 as shown.

It will be observed that when a thickness of material is interposed between the front Vand the rear portions of the tab in order to produce a wider label-receiving chamber, at

. least three thicknesses of material result;in

the case of a folder the tab port-ion is therefore thicker than the body of the folder itself. I'Iowever the tab portion is only half as wide as the body portion of the folder or less, and if as shown the lower edge of the foldedover portion of the tab is made so that it will not reach beyond the upper edge of the iiap from which the tab extends, the tab portion of-one folder may extend over the tab portion of the preceding folder, without causing any decrease in the filing capacity of the file. However a filing folder generally contains papers the thickness of which is amply suiiicient to counterbalance any difference between the thickness of the tab and the thickness of the front body member; and since the papers filed in the folder are generally of the same height or somewhat less than the height of the front or shorter flap, said papers will not reach up to the foldedover portion' of the tab -and nov useless increase over the thickness of the papers inserted in the file results.

This being the case it is thereforeobvious that the frontv flap of a folder can be made to extend above the lower edge of the folded-v over portion of the tabv without causing a decrease in the ling capacity of a file. I-Io-wever other considerations make it desirable that the front flap be flush with the foldedover portion of the tab when the folder is empty. If this preferred method of construction is followed, the short flap will remain perfectly flat when the folder is formed and a quantity of folders may be compactly packed in a perfectly flat condition in a package of minimum bulk. Furthermore the same condition obtains if the folded-over portion .of the tab is bent outwardly instead of inwardly of the folder, the resulting thickness of material thus proJecting from the rear surface of the folder remaining flush with the front flap of the next folder.

My invention may be applied to filing and indexing devices other than those shown and can also be varied in its minor details without departing from the inventive idea. The drawings should therefore be understood as being intended for illustrative purposes only and not in a limiting sense.

1 accordingly reserve myself the right to carry my invention into practice in all those ways and' manners which may enter, fairly, into the scope of the appended claims.
