'rms invention Yrelata; to s me or holder and relates more particularly to an envelope or holder for photographic negatives and the like. A general object of the invention is to provide a simple, 5 practical and inexpensive ille or holder of the character mentioned.

Photographic negatives are very easily damaged as by scratching, finger-print smudges, etc., and when damaged in this manner are unsuited m for printing and enlarging. Common or typical envelopes do not form convenient or practical holders for the negatives as they do not allow the negatives to'be viewed without removingthem and do not constitute eifective record illes for the negatives.

Another object of this invention is to provide a holder or le -for photographic negatives that effectively protects the negatives and yet allows lthem to be examined without contacting or en- 'gaging them with the hands.

Another o bject of the invention is to provide a file or holder of the character mentioned that is moistureprooi and non-deliquescent so that the emulsion on the negatives has no tendency to adhere to the holder.

Another object of this invention is to provide a holder or le that is adapted to contain a plurality of negatives so that daylight or artificial light may be transmitted through them for thorough examination.

Another object of this invention is to provide a holder or le that is adapted to contain a relatively large number of photographic negatives in a convenient and orderly arrangement, and that is adapted to be bound in a book or in a looseleaf folder, or the like.

Another object of our invention is to provide a holder or le that includes a record forbearing or receiving the exposure data, etc., of the individual negatives that are arranged in the file.

Another object of this invention is to provide a holder or le of the character mentioned that is such that the negatives may be individually removed and replaced without engaging or disturbing the other negatives in the file.

A further object of this invention is to provide a holder or ille for photographic negatives that is extremely simple and that maybe formed of a single, simple blank of transparent material.

The various objects and features of our invention will be fully understood from the following detailed description of typical preferred forms and applications-of the invention, throughout which description reference is made to the accompanying drawing, in which:

Fig. l is a front or face elevation of one form of file of the invention. Fig. 2 is an enlarged, fragmentary, longitudinal detailed sectional view taken as indicated byline 2-2 on Fig. l. Fig. 3

is an enlarged, transverse detailed sectional view taken as indicated by line 3 3 on FIRA. Fig. 4 is a view similar to Fig. 3 illustrating the manner of folding the body blank when assembling the le. Fig. 5 is a front elevation of another form of holder provided by the invention. Fig. 6 is an enlarged, transverse. detailed sectional view taken as indicated by line B-l on Fig. 5, and Fig. 7 is a transverse sectional view similar to Fig. 6 illustrating the manner of folding the body.

The le or holder of the present invention illustrated in Figs. l to 4, inclusive, of the drawing includes, generally, a folded blank or body I0, means I I partitioning or dividing the body I into a plurality of compartments C and a chart or record I2 on the body I0.

In accordance with the invention the body Il of the holder or nie may be a simple, integral sheet of transparent cellulose material of the type known as Cellophana I'he transparent material of which the body I is constructed is moistureproof and not deliquescent. The material of which the body I0 is formed is preferably clear and uncolored. The blank or sheet constituting the body I Il may be a simple, rectangular or square piece of transparent material. The body I0 is folded along two spaced parallel lines I3 to have a front I4 and two rear panels or portions I5. Where the body I0 is rectangular, as illustrated, the lines of folding I3 preferably extend longitudinally relative to its greatest dimension. The body I0 is folded so that its rear portions I5 are substantially flat against or parallel with the front I4. The longitudinal edge parts I6 of the back portions I overlap, as best illustrated in Fig. 4 of the drawing. It is to be noted that the body lll folded or formed as Just described is extremely simple and inexpensive.

The means II serves to maintain the front Il and the rear portions I5 in their proper relation and to divide the interior of the folded body I0 into a multiplicity of compartments C for receivingthe photographic negatives. Itis a feature of the invention that the means II is very simple and comprises a plurality of lines I-'I o! securing means securing together the front I4 and the rear portions I5 of the body. The securing lines I'I may belines of a suitable adhesive or may be tapes coated on their opposite sides with a suitable adhesive. In the preferred structure illustrated, the lines I1 are lines of stitching. 'I'he lines II of stitching extend longitudinally of the body, that is, they extend parallel with the longitudinal edges of the body. The lines I'I of stitching are preferably equally spaced apart and the outermost lines I1 of stitching are spaced from the longitudinal edges of the folded body so that the several compartments C are of equal width. In practice the lines l1 of stitching may extend between the opposite ends of the body III to provide s multiplicity of elongate C adapted to receive negative strips. The body Il is formed or folded so that one line of stitching I1 serves to secure together the overlapped edge parts I6 of the rear portions Il and to'connect them with the front I4. With this construction it is not necessary to employ cement or adhesive in the manufacture of the body. 'l'.he compartments C are open at what I will term then-lower ends.

Suitable notches I3 are provided in the lower edge portion lof the front I4 to occur at thelower ends of the compartments C to facilitate the ready engagement or grasping of the negatives or the negative strips in the compartments. The notches Il may be formed in the body blank before folding and forming the body I9. A

While the chart or record I2 is not an essential element of the file it greatly facilitates the cataloguing and filing of the individual negative exposures of the negative strips contained in the compartments C. The record I2 may comprise a sheet or strip of paper arranged across the upper portion of the body front I4. The record I2 is secured to the body I0 by a transverse securing line I9, such as a line of stitching. The line I9 of stitching operates to close the upper ends of the compartments C and strengthens the body III. 'I'he record I2 may bear a plurality of groups of printed lines to facilitate the notation of exposure data, finishing instructions, etc. 'I'he groups of lines 2li are above or in longitudinal alignment with the compartments C and may be numbered so that the data written on the lines may be properly related with the negative exposures on the film strips contained in the compartments C. The end portion or the upper portion of the body III reinforced by the line of stitching I9 and the paper record I2 may form a binding portion to facilitate the binding of the ille in a folder or book. Spaced perforations 2I may be provided in this binding portion of the body I0 and the record I2 to facilitate the binding of the file. The above-mentioned binding portion may carry printed matter such as advertising.

It is believed that the utility and practicability of the holder or file illustrated in Figs. 1 to 4, inclusive. of the drawing will be readily understood from the foregoing description. The film strips bearing the negative exposures may be easily inserted in the compartments C through their open ends. Data relating to the exposures and instructions concerning the finishing of the negatives may be written on the proper lines 2li so that a permanent record may be made of the exposures. The photographic negatives contained in the file are fully protected against dust, moisture, etc., and against scratching and fingerprints, etc. The body I0 is formed of a moistureproof and non-deliquescent material and the emulsion of the negatives does not adhere to it. As the body I0 of the holder or file is transparent it may be held so that light is transmitted through the photographic negatives whereby the negatives may be viewed or examined without removing them from the file. This is important as it makes it unnecessary to directly handle or engage the negatives when they are examined. If desired the le may be readily bound in a book or folder together with similar illes containing photographic negatives and when thus bound the negatives are effectively protected and yet may be easily examined at any time and removed froml the illes when desired. The holderor file is extremely simple and embodies only two parts, namely, the sheet or blank of material of which aucun thebody Ilisformed andthesheetoipaper comprising therecord I2. l

The holder 'orfile of the present invention illustrated 1n Figs. 5 to '1 'of the drawing inmunes,

v tangular sheet that is folded intermediate its ends to have a front and a back 26 in parallel relation to the front. 'I'he body 22 is preferably' folded to have its upper and lower edges and itsouter edges coincide or mate, as illustrated. It will be noted that the body 22 may be formed of a simple, inexpensive, sheet or blank of suitable transparent material. l

The means 23 divides or partitions the interior of the folded body 22 into a multiplicity of compartments C each adapted to receive a photographic negative and also serves to secure together the front 25 and the back 26 and to reinforce the body. The means 23 includes a plurality of lines 21 of stitching extending substantially parallel with the side edges of the body 22 and securing together the front 25 and the back 25. In the particular form of the invention illustrated in the drawing there are two spaced lines 21 of stitching. The line 21 of stitching adjacent what we will term the inner edge or binding edge of the body 22 is preferably spaced some distance from said edge to leave a binding portion 28 of the body. The distance between the two lines 21 of stitching and the distance between the folded side edge of the body 22 and the adjacent line of stitching 21 are equal. 'I'he lines 21 of stitching may extend between the upper and lower ends of the body 22. The means 23 further includes a plurality of spaced lines 29 of stitching extending at right angles to and crossing the lines 21 and securing together the front 25 and the back 2i. The lines 29 of stitching may extend between the opposite side edges of the body 22 as illustrated. The lines 29 may be equally spaced apart to provide compartments C of equal size and the upper and lower lines 29 of stitching are adjacent the upper and lower edges of the body 22, respectively. It will be apparent how the lines 21 of stitching and the lines 29 of stitching divide the interior of the body 22 into a multiplicity of square or rectangular compartments C adapted to receive the photographic negatives. While we have referred to the securing lines 21 and 29 as being lines of stitching, it is to be understood that they may be lines of a. suitable securing adhesive or adhesive tape. Horizontal openings or slits 30 are provided in the front 25 of the body 22 to facilitate the insertion and removal of the photographic negatives from the compartments C.` There is a slit 30 communicating with the upper end portion of each compartment C. The lower edges of the slits 30 may be curved or concaved, as i1- lustrated, to facilitate the ready grasping of the negatives in the compartments C.

The record 24 is provided to receive or bear exposure data, etc., relating to the photographic negatives inserted in the compartments C'. The record 24 is arranged on the front 25 of the body 22 at or over its binding portion 28 and may extend vertically or longitudinally of the body, as illustrated. A line 3| of securing means such as stitching serves to secure the record 24 to the portion 28 of the record 24 may be perforated at 32 to facilitate the binding of the envelope or iile in a book or folder. The portion 28 of the record is suitable for carrying printed advertising matter, etc. The record 24 may bear groups of spaced and numbered lines 33 to receive the exposure data, iinishing instructions, etc., concerning the photographic exposures arranged in the adjacent or aligned compartments C. The groups or lines 23 are opposite or aligned with the horizontal rows of compartments i C' as illustrated. The record 24 may be bent or folded back from the body front to expose the adiacent portion of the body so that the negatives in the adjacent compartments C may be readily examined.

'I'he use or operation of the le illustrated in Figs. 5 to' 'I of the drawing is substantially the same as that of the previously described form of the invention. The cut or individual photographic negatives may be easily inserted in the compartment C' through the slits 30. 'I'he compartments C are shaped and proportioned to properly receive the negatives. When thus arranged in the compartments the negativesl are fully protected against dust and moisture and against scratching and direct engagement by the fingers, etc. As the body 22 is moistureproof and non-deliquescent the emulsion of thenegatives does not adhere to it. The body 22 is fully transparent so that the negatives contained in the compartments C' may be easily and effectively examined by passing light through the body and negatives. The le or folder is constructed so that it may be bound in a 'book or folder with similar files and the record 24 is adapted to receive data concerning the several negatives con tained in the le so that a convenient record may be kept. The holder or ille illustrated in Figs. 5 to 7 of the drawing is inexpensive and comprises a single sheet of inexpensive transparent material and a single sheet of paper.
