Wa Ziw'WHi tJifl United States Patent i 3,000,123 SLIDE VIEWER Walter W. Hicks, 1003 N. Mansion Drive, Silver Spring, Md. Filed Sept. 5, 1958, Ser. No. 759,226 1 Claim. (CI. 40-63) This invention relates to an optical reflex viewer which is particularly adapted for use in examining color photographic slides.

It is an object of my invention to provide a foldable viewing device, easily assembled, adapted to receive and maintain the color slide and magnifying lens in viewing alignment.

Another object is to provide means for enabling light to be readily reflected toward the slide being viewed.

A further object is the provision of flap locking means to maintain the viewer, lens and slide in assembled and aligned relationship.

An additional object is to provide a die-cut sales folder adopted for display or mailing before separation of the blank for subsequent assembling.

Still another oject is the die-cutting and scoring at appropriate locations to enable easy separation from the blank stock and yet retaining separable junction of adjacent sections at critical locations.

Further objects and advantages of the invention will become apparent from the following description and claim, and from the accompanying drawings, wherein:

FIGURE 1 is a perspective view of the device showing the use by an individual and the light reflecting arrangement at the far end of the viewer.

FIGURE 2 is a vertical cross sectional View through the assembled viewer.

FIGURE 3 is a plan view ofthe bottom side of the device.

FIGURE 4 is a top plan view.

FIGURE 5 is a partial plan view of the side opposite to that shown in FIGURE 2.

FIGURE 6 is a top plan view of the sales or display folder which had previously been die cut to enable separation from the blank stock.

FIGURE 7 is an end elevation of the same.

FIGURE 8 is an enlarged front elevation of one of the lower tabs, while FIGURE 9 is an end elevation of the same.

In the drawings where like reference characters denote like parts, the numeral 10 refers generally to the foldable viewer made of a light cardboard, plastic or similar material.

The top, as shown in FIGURE 1, is indicated at 12, the bottom at 14, and the two sides at 16 and 18. The numeral 20 refers to the front end and the rear end at 22. A flap 24 is shown extending from the bottom 14 for a purpose to be later defined.

As will be apparent from FIGURE 6, which shows a die-cut blank not yet separated from the folder stock 26 and when in this state is suitable for mailing or for purpose of display.

The display or sales folder comprises a backing 28, top, bottom and one side 30, 32 and 34 respectively. The right side of the backing is folded over the top and the top 30, bottom 32, and the left side 34 may be folded over to present a compact unassembled package for display or mailing, with the previously die-cut blank 36 positioned therebetween.

The blank 36 is die-cut at 38, 40, 42, 44, 46 and 48 to form a panel while the edge 52 of this panel 54 is merely depressed to enable folding along this line or edge. Another depressed or folding edge 56 is made to permit the bottom flap 58 to be similarly folded. A cir- 3,000,123 Patented Sept. 19, 1961 cular cut out 60 is made in this flap 58 with short slits 62 radiating therefrom and these slits, together with a relatively short horizontal cut 64 are used to maintain a magnifying lens 65 in this flap end 58.

A vertical slit 66 has been die-cut in the main left panel 54 and another short horizontal slit 68 has been made at the edge or fold between this main panel 54 and the top flap panel 70 with the material on either side of the slit 68 being depressed at to enable folding along this edge.

Immediately adjacent this panel 54 is a relatively smaller panel 74, the top and bottom edges of which are completely die-cut at 76 and 78 with the exception of the short scoring or depressed lines 80. It will be noted that the two side edges 52 and 58 are merely depressed to also enable subsequent folding along these lines.

To the right of this smaller panel 74 is a connected second larger panel 84 which, with the adjacent depressed folding edge 82 and depressed edge 86 will also enable this panel 84 to be folded as will later be apparent. A bottom tab 88 having a circular die-cut out 90 is depressed along the edge 92 to facilitate folding as is the upper tab 94 with its depressed edge 96.

This upper panel tab 94, having an extended tongue 98, is provided with a comparative square die cut-out 100. Immediately adjacent on the right is a third large panel 102 having a common depressed edge 86 but, as in the case of the second large panel 84, having die-cut edges 104, the cut edges 106 of this panel enable easy separation from the blank. However, as indicated at 108 in some of these sections, the scored edges presents temporary retaining means but still enable later separation. Similar to the first and second panels 54 and 84, a central disc portion is die-cut from the blank, presenting an opening 110. This third panel is provided with depressed edges 119 for folding of the extended flaps or tabs 114 and 124.

In FIGURES 8 and 9, enlarged views of the lower tab 58 has been shown with the magnifying lens 65 frictionally held thereto. It will be observed that this lens disc 65 is inserted in the radial slits 62 and horizontal slit 64 to more or less insure positive engagement.

A comparative square opening 112 has been die-cut out of the upper tab 114, similar to the opening in tab panel 94. Extending from tab 114 is another smaller tab 116, die-cut and of irregular formation. However, certain of the cut side edges have been partially scored, as at 108, to temporarily maintain this corner in attached relationship to the blank stock. This scoring has also been done at other panel and tab locations so that the entire die-cut blank may be maintained until ready for separation from the display folder. To the right as shown in FIGURE 6 is another smaller tab 118 having depressed lines 121, a tongue 120 and partially scored at 108 having the depressed folding edge 122.

The perspective view in FIGURE 1 shows the use of the viewer with the direction of the light indicated by the numeral 123. The inner surface of the angular light reflecting tab 70 may be coated with any suitable material, such as DA-GLO, as has been indicated at 126.

After the magnifying lens 65 has been frictionally secured in the slits 62 and 64, and the viewer has been folded and assembled, the color slide 67 is inserted between the portions 94 and 114 where it too is frictionally secured. It is to be noted that the slide is in alignment with the appropriate openings enabling a clear view therethrough.

Similarly, the lens 65 is in alignment with the circular openings 90 and 110, as well as the opening 60 in the lens securing flap 58. It will be appreciated, as indicated in FIGURE 1, that by closing an eye the picture may be clearly viewed through this device. Of equal importance is the relatively easy insertion and removal of the color slides from the viewer facilitating rapid viewing and selection of the slides for subsequent positioning in slide carriages or for temporary storage.

With particular'reference to the display folder 26 with the die-cut viewer not removed, as shown in FIGURE 6, diagonal slits 128 and 130 have been made in the flaps 30 and 32. These slits have been arranged so that when the side flap or wing 34 has been folded over, the corners 132 and 134 are slipped into the slits 123 and 130 to more compactly form a unitary package or display folder. This arrangement additionally serves to maintain the die-cut portions in place during mailing or display until removed for forming into the slide viewer.

While a specific embodiment of my improved slide Viewer has been disclosed in the foregoing description, it will be understood that various modifications within the spirit of the invention may occur to those skilled in the art. Therefore, it is intended that no limitations be placed on the invention except as defined by the scope of the appended claim.

I claim:

A device of the character described for viewing photographic slides the bottom, top and sides of which are of trapezoidal formation, a viewing opening, magnifying lens mounted in said opening, an aligned opening in the end opposite from said viewing end, frictional closure means adapted to maintain said slide in alignment with said openings, an adjustable. reflecting flap positioned adjacent said slide and adapted to reflect the maximum of light toward the back of said slide whereby the picture on said slideis illuminated, and meansfor accentuating light comprising a layer of light reflecting substance applied to the upper surface of said reflecting flap wherein slits radiating outwardly from the opening are formed in one of the lower tabs and a horizontal slit is formed below said opening whereby said magnifying lens may be maintained in alignment, and said viewer when assembled will present said circular and square openings in horizontal alignment.
