8 Claims. ((11. 40-159) 5 frame in a vertical direction with respect to the envelope Y so that when the latter is inserted into a pocket in a supporting card said film strip or frame will likewise be auto- 3 matically centered vertically with respect to the sight opening in the card.

A further object of the invention is to provide a novel itransparent protective envelope which automatic'ally'lo cates one edge of the strip or frame contained therein .along a desired predetermined line with respect to an edge f the envelope. I

Another object is to provide anovel transparentproftective envelope for a strip or a row of individual frames :of photographic negative film, such as micro-film, said ,envelope being of a width larger than that of said strip torframe and having means therein for positioning the :strip or frames centrally between the upper and lower edges of said envelope. 7

Yet another object of the invention is to provide a transparent envelope, of the character and for the purpose set .forth, having at least one marginal edge portion which is iinwardly offset in a novel manner so as to confine the film .strip or frames and to locate the same along a desired line :within the envelope. t

,Another objectis to provide a transparent envelope of "the'character and for the purpose above described, having upper and lower marginal edge portions which. arein- 'wardly offset in a novel manner so as to confine the film :strip or frames and to locate the same centrally in said envelope. 7 r

vAnother object of the invention is the provision-of a .novel method for forming embodiments of the protective .envelope of the invention wherein the strip-locating shoultder or shoulders are formed integrally with a panel or "with the panels of the envelope.

The above and further objects and novel features of the present invention willmore fully appear from the following etailed description when the same is read in connection with the accompanying drawings. It is to be expressly understood, however, that the drawings are for .the purpose of illustration only .and are not intended as a definition of the limits of the invention.

In the drawings, wherein like reference characters refer to like parts throughout the several views, a

Fig. 1 is a front or face elevation of one form of holder or file card useful with the protective envelope of the present invention and adapted for' mounting two strips of photographic negative film therein, portions of the card being'broken away for purposes of clearer illustra- I 2,861,370 Patented Nov. 25, 1958 tion;

Fig. 2 is an exploded view, in perspective, of three plies employed in producing the holder or file card shown in Fig. I;

Fig. 3 is a vertical longitudinal sectional view on the line -3-3 of Fig. 1, on an enlarged scale;

Fig. 4 is a vertical transverse sectional view on the line 4--4 of Fig. 1, on an enlarged scale;

Fig. 5 is an enlarged face view of a first embodiment of film receiving and protecting envelope constructed in accordance with the present invention and forming a part of and included in the holder or file card shown in Fig. 1, a portion of said envelope being broken away for purposes of clearer illustration;

Fig. 6 is a fragmentary to plan view on a considerably larger scale of the envelope shown in Fig. 5, and including a strip of photographic negative film inserted therein;

Fig. 7 is a vertical transverse sectional view on the line 77 of Fig. 6; and V Fig. 8 is a fragmentary view, similar to Fig. 5, of a second illustrative embodiment of the protective envelope of the invention, said envelope having only a bottom offset marginal edge portion.

Referring to the drawings, there is shown, by way of example, one form of holder or file card with which the protective envelope of the present invention is useful. The file card shown is particularly designed for use in mounting one or more strips of photographic negative film, such as micro-film, containing several successive exposures, or one or more rows of individual frames of such film. In the illustrated embodiment, thefile card is of the standard 3 x 5 file card size and is constructed to accommodate two strips of micro-film of the 16 mm. size, or the equivalent thereof in individual frames of such film. The file card may be constructed to receive only one strip of film, or the size of the card may be increased to accommodate any desired number of strips of 16 mm. film, or two or more strips of film of a larger size. It will be apparent as the following detail description of the invention proceeds, that the protective envelope of the present invention may also be advantageously embodied in protective mountings for stamps, photographs, and other like objects of value and interest which are to be preserved. 7

As shown in the drawings, the holder or file card, indicated generally at 20 (Figs. 1, 3 and 4), is a three-ply structure consisting of a front ply 21 (Fig. 2), a rear ply 22, and an intermediate ply 23, which are all of the same length and width and are preferablyformed of smooth surfaced card stock or heavy relatively stiff paper material. In the finished article shown in Figs. 1, 3 and 4, the card plies 21, 22 and 23 are disposed in superposed relation with their edges accurately aligned, and are firmly bonded together as a single unit such that said pliesat the edges thereof are not distinguishable one from the other. This is accomplished by first coating the entire area of the available plane surfaces of the intermediate card ply 23 at opposite sides thereof with a suitable adhesive substance and then subjecting the assembly to heat and pressure sufficiently to firmly bond and in effect blend together the abutting surfaces of the card plies.

For a purpose to appear hereinafter, the intermediate card ply 23 is formed of card stock having a thickness substantially equal to the thickness of the film to be mounted, plus twice the thickness of the material which is used to form a transparent film-receiving, centering and protecting envelope 24 made in accordance with the invention.

In the illustrated embodiment, the envelope 24 is preferably formed of clear, transparent cellulose acetate ma terial having a thickness of approximately .003 of an inch. .Acco'rdingly for -the above-.rnentioneds..filrn..and

envelope 'interial thicknesses, the intermediate cardlply 23, .inathe illustratedembodiment isformed;ofreard material having athickness of approximately .01 1:: of en inch which .is deemed. sufficient-rand which'has 'been found to give excellentresults. 1 Other materialsysuch .as celluloid, cellophane, :or rigid vinyls-may be used to produce the envelope- 24, and it-will be apparent that the lt hickness oflheJinterrnediate card ply -23 .varieswith and isgoverned by.thecombined .thicknesses'of the film and envelopefltherefor. 1 Although .the front card ply Zia-and the rear card' ply 22 may beof any-:thickness desired,

said plies, as herein: shown are preferably of the same thickness .aslthatofz the-intermediate -card-ply 23 so as to.simplifyv the. manufacture of i the card 'structureandto provide a card structure which is strong anddurable, will not curl and is resistant to bending. -It1is to beunderstood-,that all-. orcer tainofthe -card-pliesx21,-22 and 23 .may, if desired be made of othermaterials such. as, for example,.t-hermoplastic. material.

The intermediate card ply 23-has 'die-cur-therein two alike obl ong.apertures 25, .25 (Fig.2) whicharedisposedin spaced-parallel relation and extend. lengthwise ofsaidply. lherapertures 25 25 extend-substantially .t hefull. length of vthetc ard ply 23 leaving relatively narrow .marginalpositionsof said ply at theopposite ends thereof. sshowndn Eigs- 1, 3 and 4, the apertures 25, 2S

'25 and openings 26, 26land 27, .27,nportions-.of the .outer .c ard plies 21 and22 project beyondsaid apertures'allthe way around the same, ,thus forming in ;-conjunction withthe apertures25,""25 elongated pockets 33 which are completely closedaround the edges thereof andzareof the proper length; width and depth'tosnug'ly receive'andre- 'tain therein envelopes 24' above referredto.

The from outer card ply 21 has die-cut therein two alike narrow windows 34, 34 (Figs. 1, 2 and 3) which are located between the ends 30, 30 of the sight openings 26, 26 and the adjacent ends 31, 31 of the apertures 25, 25. The windows 34, 34 are'of the same width as that of the apertures 25, 2S and they extend across the width of the latter and accurately register .with the same, said windows serving. as entrance openings tothe otherwise closed {pockets'"33 throughwhich.the envelopes 24,may be edgewis' inserted into the pockets and removed therefrom.

The rear outer card ply 22 has solid portions thereof "backing the entrance openings .or windows34, 34 in the finger openings 35, 35 is less than the width of the entrance openings. 34, 34, and-said finger openings are so located that thestraight edges thereof are substantially in line with the outeredges of said entrance openings.

As shown in Figs. 5, 6 and 7, the envelopes 24 of the first illustrated form ofthe invention are each in the form of a folder formed from a sheet of clear transparent .material, preferably cellulose acetate material, folded upwardly and over upon itself substantially in the center thereof to provide alike front and back panels 36 and 37, respectively, which are connected together at the folded edge and are of a width greater thanthe width of the film strips or frames to be handled and slightly less than the width of the apertures 25, 25 in the intermediate card ply. 23. The envelopes 24 are of a length less than the length of the apertures 25, 25 and such that when said envelopes .arefully inserted into the pockets 33. of the card structure the trailing endsthereof project beyond the inner edges of the entrance openings or windows 34, 34 in, thjront card 'ply 21 and partly overlap the finger openings 35,135 in' the rear card ply 22, as shown in Figs. 1 and 3.

' In order to facilitate centering of the film strips ,or frames in the oversize .envelopes 24 between the upper and lower longitudinal edges of the latter, each envelope is novelly constructed to provide between the panels 36 and 37 thereof spaced parallel shoulders or shelves 38 and 39 (Fig; 7) which extend substantially the entire length of the envelope andare disposed parallel to the upper and lower edges, respectively, of said envelope. The shoulders or shelves 38 and 39 face each other and are symmetrically disposed on opposite sides of the longitudinal center line of the envelope 24 and are spaced apart a distance slightly in excess of the Width of the film strip or frames to be handled. Accordingly, when a film matic'ally l'ocate'the same centrally between the upper and lower edges of said envelope and at the' same time confine the film strip or frame against upward and downward displacement'from central position and against upward outward displacement from the envelope.

' In the illustrated embodiment of Figs; 5, 6 and 7, the shoulders 38 and '39are formed integrally with the envelope" 24, and are conveniently and effectively produced in a novelmanner by passing the folded sheet through and between opposed 'rotary knurling tools of a fine straight knurl type, whereby short, minute, shoulderforming, teeth-like projections such as shown at 41 in the greatly enlarged views of Figs. 6 and 7 are impressed in one of the panels 136 and 37, i. e., the panel 37, of the *envelope'at and along" the upper'edge thereofi-andqcompani-on-depre'sjsions 42am simultaneously formed in the fbther panel, i; e:,"the pane1fl36; to receive said projections therein, and like projections 43 are impressed in the other panel, i. e.,- the panel 36, at andalong the lower edge 'tact with said film strip or frame, said projections will.

{extend beyond the film strip or frame and beyond the inner plane surface of the opposing panel and into the companion depressions 42 and 44 and interlock with the same. When cellulose acetate material is used to form the envelopes 24 as in the illustrated embodiment, said material is folded and the projections 41 and 43 are formed therein while the material is subjected to heat so as to soften the same sufiiciently to enable such folding and the formation of said'projections without cracking, rupturing or otherwise damaging the material.

It might be pointed out that the thickness of the envelopes 24 is not noticeably increased by the formation of the projections 41 and 43 therein, and that no increase in the thickness of the intermediate card ply'23 over that hereinbefore mentioned is required because of said projections. It is to be understood that the projections 41 and 43 may, if desired, be impressed in the same panel of the envelope.

Since the centering of the film in the envelope is in the main effected by the lower projections 43 and resulting shoulder 39, the upper projections 41 and resulting shoulder 38 may be eliminated if desired. This embodiment of the envelope is illustrated in Fig. 8, where such envelope, designated 24, is shown as having a shoulder 39 along only its lower edge. Otherwise envelope 24' is of the same construction as, and may conveniently be made in the same manner as, the above described envelope 24, except for the omission of upper projections 41 and thus the shoulder 38. a

It is believed that the utility and practicability of the novel transparent protective envelope illustrated in the accompanying drawings will be readily understood from the foregoing description and may be briefly summarized as follows. A film strip 40 substantially the length of the sight openings 26, 26 and 27, 27, or less as desired, or the equivalent thereof in individual frames of exposed film, is placed in an envelope 24 or 24' through the upper openable end of said envelope such that the leading or left-hand end thereof (Fig. 1) is substantially in line with the leading or left-hand end of the envelope, and because of the shoulders 38 and 39 in said envelope said film strip or each individual film frame is quickly and accurately centered vertically in the envelope and is retained in such position. The leading end of the envelope 24 with the film insert 40 is then positioned in the entrance opening 34 of the selected card pocket 33 and engaged with the exposed solid portion of the rear outer card ply 22, and using said card ply portion as a guide, said envelope is easily inserted edgewise beneath the front outer card ply 21 and into said pocket until it contacts the left-hand end of the pocket defined by the end wall 29 of the respective aperture 25 in the intermediate card ply 23. When the envelope 24 is fully inserted into the card pocket, all portions of the various exposures on the film strip 40 or frames are contained within the field of the respective sight openings 26 and 27 and, hence, said exposures are visible in their entirety for complete projection and viewing purposes. Data relating to the exposures may be written on the blank outer surfaces of the front card ply 21 and rear card ply 22. When the envelope 24 is fully inserted in the card pocket, endwise displacement thereof in its plane in either direction from the card is absolutely prevented because of the fully closed ends of said pocket. The film strips or frames contained in the envelopes 24 are fully protected against dust, dirt, moisture, etc., and against scratching and fingerprints, etc. Since the envelopes 24 are made of clear transpar'ent material, light maybe transmitted therethrough and through the variousfilm exposures, whereby the latter may be projected onto" a screen and magnified for viewing and examining pur-- poses without removing the envelopes or film strips from the card. The envelopes 24 or 24' may be easily removedfrom the card by merely finger bending the trailing end of the envelope upwardly outof the plane thereof and above the plane of the outer surface of the front card ply 21 through the entrance opening 34 from therear card ply side of the card by means of the finger opening 35, and then grasping the upwardly deflected end and pulling the envelopefrom the.card pocket. Although the envelopes 24 and 24' have been particularly described in connection with their use with a card, such as the described card 20, they may, when removed from the card, be used effectively as a holder or slide for film strips or frames. Thus, for example, they may be used in this manner with projectors or readers which cannot accommodate the card.

, Although only two embodiments of the protective en-' velope of the invention have been described in theforegoing specification and illustrated in the accompanying drawings,'it is to be understood that the same is not limited to said embodiments or to the particular type of insert contained in said envelope. 'Various changes may be made in the structure, some of which have been mentioned in the foregoing specification, without departing from the spirit and scope of the invention, as will now be clear to those skilled in the art. For example, the insert locating and confining shoulders within the envelope may be made in other ways and by other means, such as for example, by adhesi'vely securing to one or both panels of the envelope two narrow thin strips of cellulose acetate or other material. -For'a definition of the limits of the invention reference is bad primarily to the appendedbeing connected only at the fold between them, and

means on the inner surface of one of said panels providing an u wardly facing fiat shoulder having abrupt edges and projecting toward the other of said panels, said shoulder being engageable by an edge of the inserted film for locating the inserted film along a predetermined desired line and between the fold and the free edges of said panels.
