ninnx AND FrLiNG SYSTEM.
Application filed July 9,
To all whom it may concern: Be it known that l, JAMES FRANK vDUN- `LEAvY, a, citizen of the United States, residbecoming worn an surface capab e in the air, or if or exposed edges, underall conditions of hu-v ing preferably,
ing at Newton, in the 'county of Middlesex and State of Massachusetts, have invented new and useful Improvements in 'indexA and Filing; Systems, of which the following is a specification., -This invention relates to index and -filing systems.
More particularly it relates to tab or guide cards and to .improvements in the construc- -tion of the tab. Topreventsuch cards from d soiled in handling the tabshaveheretofore been covered` with a thinsheet of celluloid or other flexible maa durable moisture resisting of being cleaned.' This covering has customarily been ap lied by bending it overthe Atop edge o 'the tab and cementing the sheet to the front and back of the tab, thus leaving la smooth bound terial, havin to edge of Celluloid, but the side edges of the ta and the celluloid sheet on each side of it are raw or ex osed.- No glue or cement is known that wi l cover the raw edge of the tab which is exposed'between the sheets of celluloid, and make it impervious to moisture an heric conditions, as for here is cons'derable moisture the fingers of the tabs are moist, the paper the moisture and soon split tab is fingered The object of the present invention is to overcome this difficulty and to provide a sheath for the. the -tab card and. hermetically seal the raw example when tabs will absorb open where the midity and of use. This is accomphshed by settinginto the card a iece of celluloid or 'other material to which t e outer coverin of celluloid will adhere perfectly, this pieceoeheld mechanically in place in the'card.- By adhesion of the outer'celluloid binding-sheet to it, a perfectly bound tab results in which all edges of the tab are s urrounded by celluloid.
While the invention is here described and illustrated as it may b e a plied to a tab projecting from ya card', it is ob also to .2dihei" exposed edges of a card or of paloorfclotli or the like, such as the cover or eaves 'of a book.

65 'Referring to the drawings', 10 represents the'main body of the-card and 1 1'is its tab', which is -here' shown as located-a lr:t lg5j top of the card, but which may be variois'lyfloeated; 'and shaped as is customary or asma 4be reuiredin any 4articular' case,... t is portion o the' card' consists of athin sheet of eelluloid bent over the edge of th tab and adhering to both sides of the car and the inserted pieces of celluloid, fo'rming a binding. Preferablyl that the mark whic may be printed on celluloid. 'a card embodying the'in-v this is transparent, so' v characterizes the card the tabund'erneaththe In constructing so vention the card 1s iirst formed with the. por-` tion, where the tab is to be, projecting above' to be the vfinishededgeofthe card or if-more convenient formed with theentire edge thuslprojecting as'shownin` 85 Fig. 5, where the dotted line indicates :what 'is to-be the final top edge. I'nthis projecting. portion twoholes 13 are unehed, space dxs. that the sign which the ta. to bearmaybe rinte'd between them, a' d' so that the .'end edges of the tab when completed willfpass through the' places where the .holes are punched. These holes may have any suitable shape, but the circularshape shown has generallyy been found mosty convenient and advantageous. Pieces` of celluloid or like material of about thefsame thicknesses the card are then prepared of suitable size and shape to fit. said holes. `These are 'represented in Fig. 6, marked 14', and are seen in a finished tab in Fig. 1. rlhe insets may have the same color and otherwise be of similar visual appearance to the'remainder of the card. These being setin theholes 143, a thin sheet of Celluloid 15 is cemented to both front 105 and back of the card, and to both sides of the insets'covering and adhering eifectively'to thelatter on each side, being doubled over the to' edge of the card t the place where the ta is io be. then formed by 110 The tab is cutting the edge .ofthe card with a diel in the customary manner, 'the die cutting through the insets. 14, and producing the shape as may be desired. -The side sheets ofthe celluloid covering prevent the insets from-svlipfpingv sidewise out of place; andthe'shape o the "hole which embraces the inset mechanically,
as 'ap ears in Fig. 1,'1the card inclosingthe 'broadldst part of the inset7 holds the inset firmly dovetailed in position and thus pre-r vents it from falling outL edgewise, adding its mechanical grip to,theadhesive effect of the lside sheets of Celluloid covering. The result 'is that'the 'cards are of the same 'sha e as thosefh'eretofore made and of the same t ickness, but the exposed edges of vthecardboard are made im erviousto moisture -and the .,Wearingg qua 1ties 1of the guide cards are greatly increased, yproducing a-guide card which is 'practically indestructible with comf fmonu'sage. 'I 4Obviously the invention is not limited 'to' the forms of cards and tip shown, orto vcellu` loid as the material for covering the-card, or for iilling the holes 1,3; any other vsuitable material may be ein loyed in its place; but this is the most suita le material now known to me'. .It will also be observed thatv owing to the location of the insetsw'at each end of the ltabvand the faot that they areset in under 'the top 'edge of the tab," the entire sheath or side binding sheetsof Celluloid are held firmly in placeon the tab so that they cannot be pulled od even though the cement fastened thereto becomes loosened with time.
Inl the drawings, in Fig. 2 the cardboard 10 and the bindings'heet ofcelluloid 15 are seen., In Fig. 3 the section'passe's through the inset 14,- Whioh is made so d blaok for the sake of greater clearnes's and'there .is a little of the `card-boardv 1 0 [between the top of the inset andthe .ton feld in the binder 15; In Fig. .3
