A GGRPRAT'IOIT 0F DELAWARE INDEX nnvron Application led June 11,
index systems and consists primarily in se.
curing a cover or sheath of transparent sheet material to a card in s oh a manner that the sheath may expand or contract without buchling the card. This and other features will be hereinafter more fully described and pointed out in the appended'claims, and one embodiment of the invention is illustrated in the accompanying drawings, in which i Fig. 1 is a front view of aV holder and sheath; i
Fig. 2 is a rea-r view; and
Fig. 3 is an enlarged section on the line 3-'3 of Fig. 2. Y
The sheath which encloses one margin of the index card holder is ordinarilyl made of transparent sheet Celluloid which heretofore has been secured to holders or index cards'at several points bystaples or other means so that accidental separation of the cards or holders from the sheath incidental to their manipulation is prevented. The vsheath however contracts and expands in response to changes in ytemperature and humidity and las a result the card 'or holder to which it is fthe front wall being bentinwardly to form a lip 7. The strips 2 and 3 are fixed to the sheathin such manner as to prevent a pivotal or turning movement therebetween as inV constructions similar to that disclosed in the patentto Rand No. 1,302,848 in which wire fasteners are employed. By `the term fixed e as above employedand as used in certain of the claims the applicant refers to a non-rotary or non-pivotal connection between the strip and the sheath. The-front and rear wall of the sheath may be of the saine` width, as shown in Fig. This involvesa saving of material over sheaths heretofore in usein which the rearwall was wider" than the front 1924. semaine. 719,306.

Wall to provide a portion to 'which staples y could be conveniently attached.V TheVV sheet bodyl preferably though not necessarily extends tothe line connecting the lower ends of" strips 2, in which` case the strips maybe formed merely by slitting the lower margin ofthe sheetas illustrated,"andthe margin 9V 'of the sheet extends into the pocket sheath.
yVhen the strips 2 and 3 lare formed by slitting the body sheet as aforesaid, they are preferably connected to thejoutside of the `from .that ofthe' central portion 9, whereby the` inner edges of the stripsdol not; engage the end edges ofcentral' portion 9l when the Vsheat-h contracts. 1 j l Heretofore-staples have been employed to secure a sheath to a sheet-but they have been found disadvantageous becausethey catch in adjacent cardsand the holes provided for the .staples weaken the margins of thesheet so sheathe so that they lierin a plane dierent thatwh'en thesheets are of ordinary paper the staples are frequently? torn vout ofthe holes. By fastening thesheath tothe card by meansof the strips 2 and 3 the above dif-' floulties'are'overcome'becauseV the sheet is in no manner weakened by the connection, although the dimensions of the sheath can vary Without buckling the sheet 1.
As above pointed out the sheath 4 is con nected to thesheet 1 only at the ends so that the intermediate portion of the sheath is uri-- attached and pockets are thereby formed on bothsi'des of the sheet 1. Index'cards (notv shown) may be inserted in the pockets formed between the walls of the sheath' and thev sheet 1 on both sides of the sheet and'bear suitable' indicia accordingto the Subj ect matter ofthe index. Thek index card on one side may be held to the sheet 1 byinserting.y
the upper corners thereof into slits- 8 adja-v cent the top'of the sheet.
I claim: y 1. A holder for index slips comprising a sheetbody vand pocket sheath attached together by a narrow strip at'each enolV of the sheath, said Vstrips being integral l,withsaid body, and the ends'of the strips attached to .the sheath being free to move relative tothe sheet body in a direction longitudinal to theI ;V`
sheath to allow for expansion or contraction of the sheath.
2. A holder for index slips comprising a sheet having a sheath of transparent sheet Celluloid enclosing one margin thereof, said sheath having front and rear Walls united alongy one longitudinal edge, Strips on said sheet formed by Cutting slits adjacent op-vr posed edges adapted to be secured to the outer side of the rear Wall of the sheath to enable the Celluloid to expand or contract Without buckling the sheet, the intermediate p0r-` tion of the sheath being unattached toy pro# vide pockets on both sides of the sheet to receive index slips. s i f3'. A holder forpindexslips comprising --a sheet body and a f olde'dfsheathfitting over one margin of the-body,l the body being slit at eachV end to Jform V,integral stripsyand said ,strips being-secured to thebutSide/O the sheath. Y A f 4. A holder for indexslips; comprising-a card,'a sheath engaging one'margin of the card, andjstri'psfat opposite ends of the card ,125 extending laterally tothesheath, each st-ri'p having a corresponding end permanently fixed'to the card and the opposite end secured to the sheathinvoff'set relationto the card,
saidnstrips compensating' for differences in ,.130 expansion between the sheath and card.
5. A holder for index slips, comprisinga card,- a sheath engaging one margin-of the heard, 'and strips arranged in spaced relation, each having one end permanently lixe'd to the card andthe opposite endpermanently fixed to the'sheath, said strips being provided to compensate' 'for dierences in expansion and contraction between the sheath and card.
