Abstract: A display device is provided consisting of a first display panel having a first forwardly facing substantially flat surface carrying a first message to be displayed with a cut in the first display panel to divide the first display plane into a plurality of sections which cooperatively produce the first message, a second display panel having a second forwardly facing substantially flat surface for carrying a second message to be displayed and also having a cut to divide the second display panel into a plurality of separate sections which cooperatively produce the second message, structure for guiding relative movement between the first and second display panels in a predetermined path between first and second relative position for the first and second display panels, structure on the first and second display panels for intermeshing the sections on the first and second display panels with the first and second display panel surfaces facing in the same direction and for causing the first message to be exposed for

Abstract: A display device having a cabinet for mounting first and second display panels, each having a display surface for a message. The panels are mounted in mutually overlying relationship so that one of the display surfaces can be viewed through an opening in the front of the cabinet. Structure is provided for interchanging the first and second panels so that the other of the first and second display surfaces is exposed to be viewed through the front cabinet opening.

Abstract: A display device having a base, a first display, and a rotary drive for rotating the first display about a preselected rotation axis. Second and third displays are connected to the drive through a suitable connecting structure so as to be moved reciprocably relative to each other while being rotated about the preselected axis concurrently with the first display. The connecting structure may include a control lever which is pivotally mounted with portions at opposite sides of the pivot connected to the second and third displays, respectively, for effecting reciprocal movement thereof toward and from each other. The connecting structure may include a motion translating structure effecting operation of the reciprocating structure as the result of the rotation of the first display about the preselected rotation axis.

Abstract: A display device arranged to present selectively three different displays. The displays are formed by three sets of display panels with two of the panel sets being selectively movable as a unit relative to the third and movable relative to each other and to the third to provide the selectively different panel displays. Selective movement of the panel sets is effected by a control which, in the illustrated embodiment, includes a camming element which is guided in a plurality of angularly related paths to effect the desired selective disposition of the different panel sets.
