1 claim.V (el. 129;16.5)`

This invention relates to improvements in a visible margin le of the general character disclosed in my pending application for Patent Serial No. 570,652, ledvDecember 30, 1944 now abandoned, and in my issued United States Patent No. 2,303,074, dated November 24, 1942, bothrelating to extensiblefiles. I i f object of the invention is toj provide in a file assembly of the extensibley type above referred to, an improved form of carrier for data sheets or inserts which may be interchanged or substituted with ease and dispatchwhenever changes in the records are required.'

`Another object isl rto provide means whereby changes or substitutions inthe record data may be quickly and conveniently effected, without resorting to erasures, or to the rewriting of associated data that requires` no vchange or alteration.

Another object is to produce a convenient, in-

expensive, and durable assembly of carriervand insert elements, forthe purposes outlined above.

The foregoing and other objects are attained by the means described herein and illustrated in the accompanying drawings, in which:

V1=ig.,1 is a fragmental elevational view of the visible margin le providedwith a rear and a front cover, the` latter being shown in detail and with a small portion broken away.

Fig. 2 is a top` view of the Fig. 1 leassembly,

to cooperate with the links in effecting the necessary detachable connections for assembling the carriers into a unit.

' In the preferred form of the invention, the

' head end of each carrier is perforated to provide a series of aligned elongated and relatively narrow slots or slits 24. The number of` slotsor slits 24 formed inthe carriers is immaterial, Abut should be suicient in number and their spacing should be such that-adequate anchorage isprovided for interlock lugs or fingers such as 25, 26, 21, 28 of a link 22, when inserted in the. slots.

In addition to the slots or slits 24, the carriers are perforated to provide va plurality of relatively wide but shorter apertures or slots 29, which,for purpose of differentiation from the interlock slits 24, may be termed connector'apertures. All of the slots or apertures 24 and 29 extend through thecarrier, and its head flap 23, which flap is preferably integral with the carrier and lsubstantially coextensive with the head end thereof.`

The ap maybe adhesively secured flatwisefto the head of the carrier. y y Each link such as 22 is provided with Yconnector lingers or lugs 30 adapted to enter the connector apertures 29 for connecting or attachel ingone carrier-and-link unit to another similar showing the carriers interposedl between the Fig. 1y assembly,

Fig. '7 isan edge view of an assembly of dataL sheets or inserts, showing how they may be farmed out or pivotally displaced relatively in order to expose data or information rapplied thereto at locationsI other than upon the margins.

. As in the patented structurathe assembly here disclosed includes a series of links 22 for piv-k otally connecting together a plurality of carriers 20 having free or unconnected `end portions 2|.

- The carriers may be.` of any form, shape, or size,

although as shownA herein they are rectangular and of a'length exceeding their height. The

unit, as explained in the` aforesaid Patent 2,303,074. An infinite number ofsuch units may be joined together by means of the links, toprovide a compact file with all the carriers and links lying substantially yflatwise against one another. The carrier and the links may be of Writing p'aper thickness, or of a thickness approximating that of ancrdinary business card. In fact, both may be of paper or light paper board construction- 1 The complete file is illustrated by Figs. 2 and 3, with thev links and carriers under stress to sepa'- rate theml-ate'rally in order to make a clear dis#V closure of the assembly. `Normally the links and carriers of Fig. 3, for example, would all assur-'ne substantially vertical positions and would be com'- pacted'in flatwise condition to produce a leV approximating in thickness the combined thickness of the carriers, links, and covers constituting the assembly..` It may here bfe noted-that bygrasp' ing the Fig. 3 assemblybyv'i'ts front cover head 31, and` permitting `gravity-to act upon `the carriers and the rear'lcovensuccessive carriersfwill hang at progressively' lowerfelevations to dispose thevcarriers in ion arrangement and thereby expose theV lower argns of all the carriers to' view.` The width "of 'margin exposed will be gov.`

in which the necks 34 of connector lugs or hgers 39 may shift vertically.

From the region of the neck 34, the connector lugs or iingers are turned in opposite directions to extend beyond the limits of apertures 29. The terminal ends 3| and 32 of said lugs or fingers overlap the carriers adjacent to the apertures, and serve normally to preclude separation of the link and carrier. however, -by bowing the link or the carrier, or both, to'wthdraw the 'lugs orA fingers from the apertures. may be removed from the assembly, or others may be added thereto.

The notch 36 between each lug or nger and the adjacent edge of the link slightly-wider than the thickness of the carriervat the 'apertures 29, so that the link may slide along the vcarrier toward and from the lower free edge ZI'JWi-thout binding. The construction permits also a swingingeof the Ilink bodily ,relativey to' thef carrier, Ithrough 'an arc Iof :approximately'180' degrees, about a horizontal axis which :includes the notche s.36. Said axis isfshiftable toward vand ltrom `the-free -edge of the carrier, within the lim'- its imposed by the height of vapertures'ZS. Y

=The aforesaidv swinging movement `of the links through anarc approximating 180 degrees, will necessarily result in a condition such as Fig. 3 illustrates, wherein the interlock lugs 25 to.28, and the attachment lugs 30-`-30, stand out substantially `at rightangles to the carriers. In the outstanding condition, the lugs are obviously sub ject'to damage, and even in the normal condition of iiatwise relationship to the carriers, they may become caught upon other carriers, drawer partitions, or the like and .suler damage or distortion. To avoid such mishaps,V special front and rearcovers are Aprovided `for the `iileof vcarriers, designed to fully protect the lugs, b ,.[llheicovers yare illustrated `by Figs. 1 to 4.v Front cover-38 is shownfin elevation uponFig. 1, and will be seen to comprisefa at sheet of paper, fiber, light cardboard or the like, having ahead 3,1pi'ev-ided by folding thesheet upon itself -at the-top. AThe depending folded-down portion, indicated 'ati.39, constitutes av link .anchor liiap. Ferforations 49-formed in the flap are properly spacedfto receive-the lugs-orngers 2,5, 26, 2.1,' 22S, in. substantially the samemanner 'as `said lugs are reeeivedsby the interlock slots or slits of the cartiers,` That is, thel perforations 40 are spaced apart a distance -somewhat greater than the dis- ,tance-between adjacent lugs, so that iiexingfor bowing of theflap is necessaryto attach and detach the cover relative to the lugs.

- The :nap 39 may also have a pair ofapertures 4l -formedltherein at a lower elevation xthan 'apere tures 40, -to vreceive'attachment lugs such as 30 in theA event .that ythe cover'38 is to be used as a rear cover. The apertures 4l are spaced apart approximately the same distance as the attachment apertures 29 in the carrier. l A slit 42 in the flap above each aperture 4|,.isadapted toreeivega tab 43 on the face of -the cover to lock thedlap 39 to the -cover portion 3 8Qadjacent `to theg'series of' apertures 40. Y ...-,ltheV cover 38 is pierced or cut away over an area-which `includes the apertures 40 and 4l, so asfto. provide aresilient pad 44 which overlies all said 4 apertures and anylinklugs .that may extend through them. Thus, at the left side of Fig. 1, resilient pad 44 covers the lugs Z55-and i25 of the link attached to therst carrier` 20, next lto the ap 39,' "(Fg; 3). The pad preferably 'is integral Separation may be eiected,

By this means, any carrier-link unit plane of cover 38.

The function of pads 44 is to furnish a protective overlay for the lugs of the links which attach to the anchor flaps, and to relieve pressure of the cover upon the lugs as the links 22 pivot within the openings 40 or 4 I, (Fig. 4) The pads serve also as resilient means urging thelugs toward parallelism with the flap whenever the lugsare disposed at less than a right angle to the 'flap'. When the lugs are not outwardly extended, the pads rest in the In all positions of the pads,

YThe ls'ubjacent sheetis the sheet 58whichunderlies the sheet 59 except for the exposed upper, margina1 portion thereof.; The vertical distance betweenQvslits 662461 and the Mlower f edge 66"-f anylffrecord sheet, determines the visible margin exposable upon a subjacent record sheet attached thereto through the agency of the slits and the hookshaped tabs. It will be noted that the terminal end 68 of each slit 66 or 61, where the neck of a tab hook of another record sheet engages, is located directly above the base of the slit 65 of its corresponding hook-shaped tab. In a direction horizontal from the terminal end G8, the' slits 66 and 61 may extend a reasonable distance such as will enable the introduction therein, of the hook elements carried by an adjacent record sheet. The hooks of one sheet are toA be disengaged from the slits of the next sheet by slightly bending or distorting one or both of the sheets, in the middle portion thereof. By the same procedure, any number of successive record sheets may be hooked together in overlapping' relationship," tol expose an upper margin of each sheet, as illustrated by Fig. 5. The relationship of successive record sheets to one another is such that they may be swung about their connections with a hinging movement, as suggested by Fig. 7,

thereby to expose to view the bodies of all the sheets, as well as the margins thereof, for the reception of data to be printedor written thereon. Such disposition ofthe record sheets, of course, is possible only when the record sheet assembly is removed from the carrier `which ordinarily supports the record sheets.

The carrier, indicated generally by the character 20,v may be a single flat sheet of suitable paper, the upper end of which is shortened somewhat in length to furnish the head iiap 23, this flap being folded down and adhesively secured to the forward face of the carrier sheet. The con.

nector apertures 29 and the interlocking slits 24 previously referred to herein, extend through both the body and the head flap of the carrier. The ends of the head flap are indicated at 69, and are located at a distance from the side edges and 1| of the carrier. The lower edge 2| of the carrier is a raw edge, that is, no ap is present along said lower edge.

In order to provide side pockets at the face of the carrier, for accommodating the end portions 12 and 13 of all the record sheets, the side margins of the carrier are folded along the edges 10 and 1I, to overlie a limited area of uniform'width vertically adjacent to the side edges of the carrier. The fold members which overlie the forward face of the carrier, are indicated at 14 and 15. Near the upper ends of thefold members, the carrier body is slitted horizontally, from approximately the `location 16 to the adjacent side edge of the carrier and through this slit the upper end of the fold member is passed to the rear of the carrier body, where it is adhesively attached thereto. The broken line 11 indicates the upper end ofthe fold member, which is stuck to the rear face of vthe carrier body. Said upper end follows the contour of the corner of the carrier body, which may be rounded as herein disclosed. y In initially forming thefold member, it is separated from the body of the ycarrier along the full length of the corner, from the line 11 to the outer end 18 of the horizontal slit 16. Where i the record sheet pocket of the carrier, is thereby established where the tab 8|) passes through the carrier at 8 I. The lower extremity of said pocket is located vertically above the lower edge 2| of the carrier, so that the hooked tabs 6| and 62 of the lowermost record sheet will have the protection of the backing eiect furnished by the lower marginal portion of the carrier.

A carrier constructed as above explained hasy the advantage of extreme simplicity, substantial durability, and maximum supporting ability for hingedly connected record sheets. Moreover, such carrier can be manufactured at minimum cost, with the use of simple machinery. The side pockets formed by the side fold members 14 and 15, serve to tightly hold the vertical end portions of the record sheets, and since the fold members are integral with the carrier body, substantial resistance to bending of the carrier in a horizontal direction is effectively induced. The manner in which the end anchorage portions of the fold members is elTected, insures a sturdy and durable construction having a long, useful period of service.

It is to be understood that record sheets of any type other than that illustrated herein can be accommodated by the carrier described. For example, a rectangular, plain record sheet might be applied to the carrier and held in place thereon by means of the fold members 14 and 15. Should it be desired to omit'the margin along the lower edge 2| of the carrier body,the fold members 14 and 15 might be extended downwardly so as to meet the carrier edge 2|, thereby placing the lower terminus of the side pocket at 4the same elevation as the edge 2| What is claimed is: l

A record assembly which consists essentially of a plurality of record sheets arranged in echelon formation to expose a writing area along a longitudinal edge of each sheet and each sheet having an opposed longitudinal hinge edge, a pair of hook-shaped tabs along the hinge edge of each sheet and in substantial parallelism therewith, the tabs having free ends extending outwardly beyond the hinge edge of the sheet and being separated partially from said edge by short slits extending lengthwise along said hinge edge, leaving a neck connecting each tab to the hinge edge, free ends of the tabs projecting in opposite directions lengthwise of the sheet, each sheet being slitted opposite and spacedfrom each tab neck a distance approximating the width of the Writing area, theslits of each sheet being substantially straight and running substantially parallel tol the hinge edge, each' slit being of a sufficient length to accommodate therein one of the tab necks of an adjacent sheet, the sheets being arranged with the hinge edges of the sheets parallel and withfthe tabs and slits of adjacent REFERENCES CITED 1 i'lhey .following references :..are .of'f--frecord- 1n*l the file nfaliihis patent: 1 UNITED STATESPATENTS limb@ l 1,4fl9. 194 '155.51.1997 .1.3745236 Number FOREIGNy PATENTS --Qlmtry Date
