' Oct. 8, 1963 J. D. DEsMoND SLIDE VIEw ASSEMBLY Filed Deo. 12, 1960 ,7m fm 5 fm 1m J United States Patent O 3,106,029 SLIDE VIEW ASSEMBLY John D. Desmond, Philadelphia, Pa., assigner to Container Corporation of America, Chicago, Ill., a corporation of Delaware Filed Dec. 12, 1960, Ser. No. 75,275 1 Claim. (Ci. 4o-62) This invention relates to visual aids of the type commonly used for education or amusement, land more particularly to a slide view device.

The invention comprehends an improved construction 'and arrangement fora slide view device of the type in which a card is slidably mounted in a guide for manipulation to provide alternating sets of printed matter, such as lines orf printing, pictures, or blank areas, which may be viewed through spaced slots in the gnide.

It is an yobject of the invention to provide an improved rslide view `device lof simple design and construction which [can be easily formed from a single blank of sheet material and which can be readily assembled.

A more specific object of the invention is the provision of a slide View `device comprising la card, having alternately spaced areas which are printed or blank, which is slidalbly mounted in a guide, having alternately spaced slots Itor cooperation with the areas on the card.- These and other objects of 'the invention will be apparent from an examination of the following description and `drawings wherein:

FIGURE 1 is la fragmentary front elevational view of a slide view device embodying features of the invention;

FIGURE 2 is a rear ielevational view of the structure illustrated in FIGURE 1;

FIGURE 3 is a transverse sectional View taken on line 3 3 of FIGURE 2;

FIGURE 4 is a detailed front elevational view of a portion of the structure of FIGURE l, illustrating the relationship between the spaced areas on both the slide and guide members of the device; and

FIGURE 5 is a top plane view fof a blank of sheet material from which the device of the other views is formed.

It will be understood that certain elements have been intentionally omitted from certain views where they alleV illustrated to better advantage in other views.

Referring now to the `drawings for a better understanding of the invention, and particularly to FIGURE 5, it will be seen that the device comprises a slide member, indicated generally lat 10, adapted to be slidably mounted within a guide member, indicated generally at 12. The entire device can be formed from a blank 14 of a suitable sheet material such as foldable paperboard. As seen in FIGURE 5 the slide and

guide members

10 and 12, respectively, are separated from each other by a perforated line 16 in the blank 14, so that in 'assembling the device the members and 12 are separated from each other to divide blank 14 into separate parts.

Still referring to FIGURE 5, it will be seen that slide 1t) is a generally flat H-shaped panel having at the top and bottom ends thereof pairs of end portions 20 which are of greater width than the center portion 22 so as to project outwardly therefrom and define therewith a pair orf recesses 24 on opposite sides of the slide. At one end the slide may be provided with an opening 26 to facilitate in the operation `of the device in a manner explained hereinafter.

As best seen in FIGURES l and 3 slide 10 is provided with a plurality of spaced lines 28 'of printed material. The spacing of the lines 'of printed material from each other will be discussed in connection with the guide member.

3,106,029 Patented Oct. 8, 1963 The guide 12 includes a at generally rectangular main or center panel 30 having hingedly attached to opposite sides thereof, along longitudinal score lines 32, a pair of slide member receiving anges 34. Each 'of the ilanges 34 includes a relatively narrow elongated rectangular retaining strip 36 which extends the entire length lof the guide panel 30. Projecting outwardly from a medial portion of each retaining strip 36 is a glue flap 38 which is also relatively narrow and elongated but which does not extend for the entire length of the retaining strip. rllhe length lof the glue ilap is less than lche vlength of the center portion 22 of the slide for a reason which will be described later in connection with the operation of fthe device.

The center panel 30 of the guide member, as best seen in FIGURES 1 and 4, is provided with a series of alternately spaced lines of printed material 40 between which lare located la series off alternately spaced slots 42. For illustrative purposes the material 40 is shown as series of the letter B. It will be seen that 'the spacing between the lines of printed material on the guide panel 30 correspond to lthespacing of the lines on the slide member 10 and also to the spacing of the slot-s 42, so that by shifting the slide within the guide rto alternate positions different sets olf printed areas illustrated by the alternate series of the letters A and C, can be viewed through the slots in fthe guide member. The guide member may Ialso be provided with an yopening 44 to facilitate Ioperation lof the device in cooperation with the opening 26 in the slide member.

To assemble the device the slide member 10 is separated rom the guide member 12 of the blank 14 by dividing the blank along perforated line y16. The slide is then placed with its tforward surface, having the printed areas, in juxtaposition with the rear surface of the center panel of the guide member. It will be seen that the width of the slide member 'at its widest part is approximately equal to the width of the center panel 30 of the guide member.

After the slide member has been placed on the guide member the retaining flanges 34 are folded over with the glue flaps 38 radhesively secured to the back of the guide center panel 30 and with fthe end portions 20 of the slide tucked under the ends of the retaining strips 36 of the guide iianges 34. Thus, the slide is r,free to move lengthwise within fthe `guide member, and the length or extent lof the movement is limited by the relationship of the 'glue flaps to the end portions of the slide. As previously stated, the `distance between the end portions iof the slide is greater than the over-all length of lthe glue flap of the guide, so that the inner edges olf the end portions of the slide are abuttably engageable alternately with 'the opposite end edges of the glue flaps, and the spacing of the printed material is so arranged that when the slide is in its upper-most position one set of printed areas is visible through the slots from the yfront side of the device and when the slide is in i-ts other position the other set of printed areas is visible through the slots of the guide member.

Although in order to illustrate this invention the device has been represented Ias having -two sets of printed areas on the guide member which could be alternated by placing the slide in either one of two positions relative to the guide, it will be understood that more than two positions could be provided. Also, instead of providing two different sets of printed `areas on the slide member there could be provided lone set orf printed areas alternated with blank Iareas.

In all of the various arrangements for which this device can be adapted the real essence of the invention lies in the novel arrangement whereby the device can be formed from a single blank of sheet material and wherein the glue flaps serve as a novel retaining means for the slide card. Because the slide can be easily slipped in and out of the guide member it is also possible to use the guide member with ra lplurality of different types of slide members having diierent printed legends thereon.
