April 1, 1958 R. A. SHOAN TRANSPARENCY FILE Filed Sept. 26, 1955 @www An/5.

United tates Patent TRANSPARENCY FILE Raymond A. Shoah, Clarendon Ellis, lli. Application September 26, 1955, Serial No. 536,358 4 Claims. (Cl. t0-158) The present invention relates generally to files for film transparencies and more particularly to a file card which is provided with a plurality of pockets for holding a plurality of transparencies and which is constructed and indexed in a manner such that any desired transparency can be quickly located and removed therefrom.

The word transparency as used herein is` intended to include within its scope film, film slides, and the like.

The objects of the present invention are: to provide novel transparency tile which is capable of holding a large number of transparencies and which permits one to quickly locate and readily remove any desired transparency without handling any other transparency; to provide a transparency le which includes improved means for identifying the transparencies held therein; to provide a transparency tile which permits the transparencies held in the tile, as well as additional identifying data, to be viewed by transmitted light; to provide an improved laminated tile for holding transparencies; to provide a file card for holding transparencies which includes an upper marginal area which is scored to simplify the renioval of selected portions thereof so as to thereby provid an upwardly extending index tab in any of a plurality of preselected positions at the upper end of the le card; to provide a file card for transparencies which includes improved means for identifying and/or locating any desired transparency; and to provide a paperboard tile card type transparency holder which is of simple and inexpensive construction and which is rugged and durable in use.

@ther obiects and advantages of the inventiony will be understood by reference to the following description accompanying drawings which illustrate various aspects of the invention.

ln the drawings:

Figure l is a front elevational view of a transparency tile formed in accordance with the present invention which is adapted for holding a plurality of iilrn slides, two of which are shown in position within the file;

Figure 2 is a partial sectional view taken along the line 2 2 of Figure l; and

Figure 3 is a partial sectional view taken along the line 3-3 of Figure l.

1B eferring to the drawings, the transparency tile 1 is rectangular in outline and is arranged to receive twelve film transparencies' in three parallel rows of four each. However, it will be understood that the transparency file may be arranged to receive any desired number of hlm transparencies, and the number of pockets to receive them in any row and the number of rows may beY varied as desired.

Preferably, the transparency tile l is made of paper and. paperboard; however, other suitable materials may be employed. The transparency le is laminated and consists of a backing sheet 3, an intermediate sheet 4.y and a front or facing sheet 5. The sheets 3', 4, and 5v are suitably formed as will be hereinafter described and l .ice

adhesively secured together to form the completed transparency lile l.

The transparency tile l is generally rectangular in form and of a suitable size to support the desired number of film transparencies. Each of the laminated sheets 3, 4, and 5 have outside dimensions identical with, and therefore extend to, the outer edges of the transparency le l. The intermediate sheet d is aligned with and ad-V hesively secured to the backing sheet 3 and the facing sheet 5 is aligned with and adhesively secured to the surface of the intermediate sheet 4 opposite the backing sheet 2.

The rectangular backing sheet 3 must, for the purposes of. this invention, be of a material which is capable of at leas-t partial-ly transmitting light therethrough and must have a surface which is capable of receiving suitable imressions from a writing implement such as a pen or pencil. ln addition, the backing sheet should be capable of being distorted at least to a slight extent and it should have sutlicient strength to resist ripping or tearing when strained. Various relatively thin, transparent or translucent sheets are suitable for this purpose. One such sheet which l have used is #69 whiteV offset paper.-

The intermediate rectangular paperboard sheet 4 may be thicker and somewhat less liexible than the backing sheet 3. lt is not necessary for the intermediate sheet 4 to transmit light and consequently an inexpensive opaque sheet such as #27 strawboard may be used. 'l'he intermediate sheet l is provided with spaced rows of uniformly spaced transparency receiving apertures 6 of dimensions slightly larger than Vthe film transparencies which. are to be held in the tile, thereby providing recesses within which the film transparencies may be positioned. in order to maintain the transparencies securely 'within the transparency file, as will hereinafter be made clear, the thickness of the intermediate sheet l is desirably slightly less than the thickness of the lower marginal portions of the film transparencies 2.

rlhe. intermediatey sheet i is also provided with an 40 equal number of relatively narrow, elongated apertures 7, one of which is located adjacent each of the apertures d. ln the illustrated tile l, the apertures 7 extend horilZontally and arey positioned immediately below each of the apertures 6. However, it will be realized that the shape and size of the apertures 7 as well as their location relative tothe apertures 6 may beY varied considerably.

The facing sheet 5 is formed of suitable paper or paperboard material which has sufficient strength to re'- sist ripping or tearing 'when strained and at the same time permits at least a slight amount of distortion. The facing sheet 5 must also have a smooth-surface which is capable of receiving suitable-impressions' from a writingimplement. While the facing sheet 5 neednot be opaque, it is desirable that either the intermediate sheet or the facing sheet or both be opaque for reasons which will hereinafter become clear. Various' paper or relatively thin paperboard sheets are suitable for use in forming' the facing sheet, one suchy sheet being ll() index board.` The facing sheet 5' is provided with'Y spaced rows of uniformly spaced apertures 8 which vare equal in number and inspacial arrangement to the apertures 6' in the" intermediate sheet d; The apertures 8 have the same length and slightly less height than the apertures 6, and are positioned within the sheet 5 so that its upper and side edges are aligned with the upper and side edges of the apertures 6 in the sheet 4.

the facing sheet 5 extend over the lower marginal portions ofthe apertures d, and with underlying portions of the backing sheet 3, form pockets l@ for receiving the lower Since the height of the apertures S is less than the height of the apertures 6, portions 9 of marginal portions of film transparencies 2 which are to be held within the transparency file. This construction also provides suitable recesses immediately above the pockets for receiving Vthe remaining portions of the film transparencies 2.

Since the intermediate sheet 4 is slightly less in thickness than the lower marginal portion of the film trans` parencies 2, the film transparencies must distort the portions of the backing sheet 3 and/or the facing sheet 5 which form the pockets 10 as they are inserted into the pockets. This is clearly illustrated in Figures 2 and 3. The tight engagement of the film transparencies within the pockets 1li of the tile minimizes the possibility of the inadvertent dislodgement of the film transparencies from the pockets.

The facing sheet 5 also includes a plurality of relatively narrow, elongated apertures 11 which are identical in number and position with the apertures 7 in the intermediate sheet 4. The apertures 11 are aligned with the apertures 7 and provide recesses in the file 1 within which underlying portions 12 of the backing sheet 3 are visible. The underlying portions 12 of the backing sheet provide title areas for the film transparencies Z which are located in the file.V

As previously indicated, either or both the intermediate sheet 4 and the facing sheet 5 are preferably opaque so that light may be transmitted only through the areas encompassed Within the apertures d, 7, 8, and 11, whereby, by directing the transparency file towards a source of light, both the film transparencies within the file as well as their titles will become visible by trans-illumination for purposes of identification. Such a source of light in a darkened projection room may be only that escaping from the top of a projector.

An upper marginal end portion of the facing sheet 5 is provided with suitable score lines 13 which divides the upper end portion of the facing sheet into five equal, longitudinally extending sections 14. The score lines 13 provide a visible guide for selective removal of any four of the sections 14, thereby forming an index tab at any one of live preselected positions at the upper end of the file. It will be understood that the number of sections 14 which are provided by the guide lines 13 may be varied as desired. The index tabs provide a suitable location for writing titles or information which will generally identify the film transparencies held in the file.

For convenience during use, each of the pockets in the file may be numbered as indicated at 1S and the film transparencies which are placed in the pockets may be similarly numbered as indicated at 16 may be easily positioned in the file. may give an identifying number of the transparency file itself as indicated at 17 and this same number may also be suitably positioned on each film transparency in the file as indicated at 18. yWhen the transparency, file and the lm transparencies are so indexed, it is a simple matter to locate the proper position of any film transparency in its appropriate tile after its removal.

If desired, the backing sheet may include apertures located within the central area of the apertures 6 and 8 as indicated in dotted outline at 19. A sufficient amount of the backing sheet 3 must remain Within the peripheral boundaries of the apertures 6 and 8 to provide a suitable backing for the outer margins of the film transparencies 2. In this construction, a somewhat greater amount of light will bc transmitted to the central area of the film transparencies than in the previously described file construction.

When the film transparencies 2 are positioned within suitably titled and indexed transparencies filed in accordance with the present invention, it is not necessary to remove selected transparencies prior to their projection in a darkened room. There is normally sufficient light which is emitted from the projector for the projectionist to view both the film transparencies 2 and the titles in In addition, one

so that they an otherwise darkened room. Any given transparency may easily be located and selectively removed for viewing. Afterwards, it is also a simple matter to again relocate and reinsert the selected transparencies Within the file either during the period of projection, or later, as desired.

The described transparency file is capable of holding a large number of transparencies in an orderly fashion. In addition to the various desirable features which have been set forth above in connection with the description of the transparency file, it is inexpensive to construct and rugged and durable during use.

While this invention has been shown in connection with the details of a certain embodiment of the invention, it is obvious to those skilled in the art that it is not so limited, but is susceptible of various changes and modifications without departing from the scope of the invention. Various features believed to be new are set forth in the appended claims.
