Claims.

This invention relates to display devices.

It is an object of the invention to provide a novel device, whereby, as, for instance, in a souvenir postcard, a plurality of scenes may be presented to view by the simple operation of sliding one part with relation to another, and wherein the resultant visualization may be either of the individual scenes as desired, or by a rapid presentation to give the effect of a moving picture.

It is an object of the invention to provide a simple device for bringing into view any one or more of a plurality of scenes in connection with a device which may take the form of a souvenir postcard or like device, where, if desired, the scenes may be presented in rapid succession so that the result may approach the effect of a moving picture, and where the structure is effected by simple parts, assembled cheaply, and arranged compactly.

It is an object of the invention to provide a device whereby a plurality of scenes or views may be housed compactly, and yet may be presented automatically for individual inspection at the will of the manipulator.

Other objects of the invention will be set forth hereinafter, or will be apparent from the description and the drawings, in which is illustrated an embodiment exemplifying the invention.

The invention, however, is not intended to be restricted to any particular construction, or any particular arrangements of parts, or any particular application of any such construction or arrangement of parts, or any specific method of operation or use, or any of the various details thereof, even where specifically shown and described therein, as the same may be modified in various particulars, or may be applied .in many varied relations, without departing from the spirit and scope of the claimed invention, of which the exemplifying embodiment, herein shown and described, is intended to be illustrative only, and only for the purpose of complying with the requirements of the statutes for disclosure of an operative embodiment, but not to show all the various forms and modifications in which the invention might be embodied.

Device in, shown on the drawings, may be formed from sheet material which preferably is of substantial thickness, although it can readily be understood that other materials and expedients may be resorted to for making device Hi. In the embodiment disclosed, a plurality of blanks l2, l4 and iii are cut or otherwise formed from the sheet material. Faces l3 and 25 of blanks l2 and M may have advertising or similar display matter imprinted thereon or otherwise applied thereto. Blank 12 may have a main rectangular body 22, and has a plurality of flaps 24, 26 and 28 at the boundary edges of main body 22, and a pair of tabs 30 extending beyond an edge 32 of body 22.

Blank 16, as shown in Fig. 5, has a main body 34 substantially of the same length as body 22; in addition, a pull tab 38 extends from edge 38 of body 34. Blank H3 with certain parts to be described is to be assembled between blanks l2 and I4. For this assembly, flaps 24 and. 28 first are folded inwardly, on fold lines 44 and 46, and down towards but free of body 22. Flap 26 and tabs 30 are now folded along the respective fold lines 49 and 42, towards body 22, and

into position to overlie flaps 24 and 28. Flap 2t and tabs 30 are new adhered, by suitable cement-- 3 ing means, to flaps 24 and 28 at their points of contact 41 and 49.

With blank it and its assembled parts properly associated, and other operations to be de scribed performed, blank l may now be positioned upon the free surfaces of flaps 24, 26 and 28 and tabs 39, and are held there by any suitable cementing means, such as glue, mucilage or the like. Blank M, which may take the form of a simple rectangular piece, is substantially equal in area to main body 22. The assembly of blanks l2 and l l in this manner will provide a mouth 48 at one end of a receptacle thus formed. Mouth 48 will be reduced from the width of body 22 by the total width of tabs 3t.

Body M of blank It is of a width equal to that of mouth 48; at its rear end, a pair of cars 52 extend laterally from body 34. The total width of body 34 at cars 52 is that of body 22. Thus, when blank i5 is fitted between blanks i2 and M, with flaps 24 and 28 folded over, ears 52 are received within the folds formed by the overlapped portions of flaps 24 and 28. Tabs 30, when folded and secured as described, are in the path of move ment of cars 52, and thus serve as stops.

Now in the actual assembly, a plurality of leaves E i are disposed, superposed one upon the other, as shown in Fig. 10, with their end edges 56 forming a regular staggered or stepped pattern. Each of the leaves of the set may have a scenic view upon its face 58. These views will thus be in position to be presented to View in the manner to be described.

With leaves 5 superposed upon each other, as shown in Fig. 10, to form steps fill, a suitable adhesive is applied along these steps. Leaves 54, retained in the stepped relationship, are turned down against face 62 of a flexible strip 64. Strip G4, which may be of cheesecloth or gauze, is of a length such that it will be capable of being anchored to one of blanks I2 and i4, and to blank It, so that blank i5 may have limited movement in relation to the assembled blanks i2 and M, in the manner to be described.

Blank l3 has a cut-out 66 to leave a clear space with relation to blank M, when blank I6 is pushed completely into receptacle 5%. Strip 64 is adhered at '58 to blank M at the position this cut-out assumes when blank it has been pushed to be housed substantially completely between blanks l2 and M. At the same time that adhesive Was applied to steps 6% it also was applied to a portion iii of face 72 of the topmost leaf 54. An end M of strip projected beyond face 72 and also carried adhesive. Now both portion 10 and end M are adhered to face it of blank I6 so that end it is positioned immediately at edge 18 of cut-out 5 5. Now blank l 6 may be pulled out of space 8% within receptacle 593 until ears 52 engage tabs 30 without hindrance from the anchored ends of strip 64.

Strip E34 will be pulled by blank l6 until end 14 is positioned outside of space 80. When blank I6 is pushed back into space 88, strip 64 tends to curl upon itself, as shown in dotted lines in Fig. 9. Leaves 55, in turn, are made to turn and to move into superimposed relation, one upon the other in succession, as blank it moves into space 85. Since a very small section 82 of each leaf is adhered fiat against face 84 of strip 64, each leaf is caused to move to a position where it is substantially parallel to that particular portion of the strip; as that particular portion of the strip curls itself in'going around the bend, the leaf also will rotate around the moving pivot, as de- 4 picted in Fig. 9. Finally, after all of the leaves have been rotated into superposed position, blank l6 will continue into fully collapsed relationship.

The end motion of blank l6 causes strip 64 to bunch within space as blank IE pushes the rest of the fabric back into that space. Cut-out 65, in that case, serves as a housing for the bunched material, and prevents bulging of blanks l2 and M, or any excessive strain at the joints.

When blank l6 has moved fully into space 813, only tab 36 extends and provides means for engaging and pulling blank I 6 and the attached strip out of space 80. When blank Hi is pulled in this manner, leaves 54 first move out of space in their fixed superposed relationship upon blank l5. Then, as strip 64 is placed in tension from its anchor point 68 and becomes taut, the first leaf 86 will be turned by the turning of strip M at that position, and will present whatever picturization may appear on its face, and likewise the picturization upon the next adjacent leaf. Continued movement of blank i5 will cause further rounding of strip 64, and, therefore, rotating movement of that next adjacent leaf out of its horizontal position, thus, in turn, exposing the next leaf and its picturizations. This operation is continued until the last leaf is exposed. This can be the leaf directly attached to blank iii with the end 74.

Many other changes could be effected in the particular constructions, and in the methods of use and construction, and in specific details thereof, hereinbefore set forth, without substantially departing from the invention defined in the claims, the specific description being merely of an embodiment capable of illustrating certain principles of the invention.

What is claimed as new and useful is:

1. A device including a pair of substantially coextensive members fixed in relation to each other, a slide movable between the members, a strip extending between and secured to the slide and a selected one of the members and a plurality of leaves, the leaves, when the slide is positioned substantially wholly between the members, being superimposed one upon the other and then being positioned between the slide and the selected member, and the leaves, when the slide is moved out from a position substantially wholly between the members, being rotated in spaced radial relationship to a position substantially on top of the selected member.

2. A device including a pair of substantially coextensive members disposed one upon the other, a plurality of leaves of substantially identical dimensions, a strip of flexible material, the leaves being disposed with the end edges of the superposed leaves stepped in regular pattern, the faces of the stepped end portions being adhered flat against the face of the strip, and a slide between the members, the strip being secured between the slide and a selected one of the members, the strip being of a length to extend outside the members when the slide is moved out from between the members, the strip and the slide providing means for moving the strip and. the leaves with relation to the members to position the strip and the leaves wholly between the members and with the leaves collapsed and superposed one upon the other between the members, and to extend the strip outside of the members and thereby to rotate the leaves with relation to each other and the members to a position wholly outside the members.
