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 timing apparatus for giving an indication of the passage of a preselected time interval, which timing apparatus consists of a body to be supported on a surface, a timer mechanism on the body including a trigger that is movable between a) a set position and b) a return position, structure on the timing mechanism for moving the trigger from its set position to its return position within a preselected time interval, and structure for repositioning the body relative to a support surface for the body as an incident of the trigger moving from its set position into its return position, with the body in an operative position on a support surface for the body, to give a visual indication of the passage of the preselected time interval.

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 wherein a pleated sheet is retained in a carrier defining opposed pockets receiving the opposite ends of the pleated sheet. Stops are provided at opposite sides of the carrier for engagement by opposite side portions of the pleated sheet for limiting lateral expansion of the pleated sheet. The spacing between the stops is preselected to maintain the folds of the pleated sheet suitably compressed to have a height substantially equal to the depth of the pockets.

Abstract: A sign construction having a plurality of movably connected panels including a mounting panel and panels successively hung from the lower edge of the mounting panel. In the illustrated embodiment, the sign construction includes an upper mounting panel having structure for securing the mounting panel facially to a windowpane. The panel portions hanging from the mounting panel define selective information-conveying sign structure and, in the illustrated embodiment, include an upper panel portion and a lower panel portion which are hingedly connected to permit the lower panel portion to selectively hang downwardly from the upper panel portion or be retained between the front face of the upper panel portion and the windowpane as a result of hinged swinging of the lower panel portion upwardly from the hanging disposition. The connection of the upper edge of the upper panel portion to the lower edge of the mounting panel, in the illustrated embodiment, is provided by a hinge.

Abstract: A ceiling hanger adapted to be removably installed on a horizontal supporting strip of a tile ceiling structure wherein tile panels are provided with edge portions resting on opposed edge portions of the supporting strip. The hanger includes a plate having a U-shaped end portion embracing one edge of the supporting strip, a midportion underlying the supporting strip, and a retaining clip embracing the opposite edge of the supporting strip and retaining the plate midportion juxtaposed to the underside of the supporting strip. The plate further includes a distal hanger portion which is bent downwardly about a connecting portion of the plate to provide a support such as for hanging an advertisement or the like from the ceiling supporting strip.

Abstract: A display system having a shelf rail defining a pair of vertically spaced parallel confronting channels with a display element removably mounted to the shelf rail by means of one or more mounting clips. Each clip is defined by a base wall having upper and lower edge portions received in the channels of the shelf rail and a support wall having a connecting portion projecting forwardly from the base wall of the clips and an upright portion defining with the base wall an upwardly opening channel for receiving an edge portion of the display element wall. The display element wall may be provided with an opening slightly larger than the cross section of the connecting portion of the clip so as to provide a secure removable mounting of the display element on the clip.

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.
