DISPLAY APPARATUS.

Application filed December 1, 1926, Serial No. 152,034, and in Switzerland November 19, 1926.

This invention relates to an automatic inscription and indication changing apparatus, which can be used for example for adverti ing purposes. This apparatus is characterized by a large number of individually movable panes arranged in a display surface so as to be movable in relation thereto, these panes being so controlled selectively from or pattern gear operating similar to a jacquard gear, that the one or other of the panes are moved relatively to the display surface according to the pattern, thus producing an inscription or illustration standing out in relation to its surroundings. The accompanying drawing illustrates an embodiment of the invention. Figure 1 is a side view partly in section, Figure 2 is a front view and Figures to 5 show details. The display surface for the inscriptions and inijlications consists of similar individually movable panes arranged in a frame ae by side and above and below one another, \lillflll when set stand up sharply against a bacligrouiul and which each consist of an indicating plate, which can be swung about a iizcntal axis 6 in the frame a from a 'ertical position (the indicating position) to a h zontal position out of use position). The form of these panes?) is so designed that individually they do not form a complete inscription or illustration, but only by the combination of a sufiicient number of panes Z; does an inscription or illustration which can be varied in accordance with the combination of panes and their number ap pear on the display surface.

lilac-h pane Z) has an ear (Z (Figures 3 and into which a rod 6 is jointed, which is connscted at its other end with a lever f. From the lever f turnable about the point g hangs a la not rod 7i. Beneath these tappet rods 7a are matrices c' arranged in groups, which are secured around a drum j, which for ex ample in the present case has six sides, and carries on each side one of the matrice groups. The matrices secured to the sides o hc drum are each formed with two parallel rows of differently formed and arranged notches i or with only one row of notches on one edge, or with no notches at all, according to whether all or only some of the tappet rods are to be left unoperated, or all are to be raised, similarly as this is effected in jaccpiard mechanism, to which the present patterning method corresponds. One of these matrices i is shown in detail in Figure The drum y" is rotatably supported. Its shaft 7' carries a slotted Geneva wheel t, which can be rotatedintermittently by the tooth k of a one-tooth wheel 7c. The latter rotated from a toothed wheel Z coupled to it and which is driven by a toothed wheel Z. This wheelZ is secured upon a shaft rwliiclr can be driven by any desired motive source. The shaft 7* which carries the toothed wheel Z is provided with a cam disc 8 furnished with two diametrically opposite cams. 1

The hub of the Geneva wheel t is provided with a groove t in which engages the forked end of a lever m. This lever m has a throw over ring m which carries two pins m which engage in the groove of a grooved shifting cam a. A groove 0 in the hub of the cam disc 3, in which the lower end of the lever on rests saddle fashion, forms the fulcrum of the forked lcverm.

The cam disc 6* co=operates with a spring controlled two armed lever 32, which is connected by a rod and lever gear 7) with two slidably guided suspended bearings g for the drum shaft j, so that the drum 7' can be raised and lowered vertically which it will be understood must be efi'ected when the tooth is is outof engagement withtheLGenova wheel t. The operating suitably arranged with this in View, the. rotation of the drum j only taking place when it in the lowest position, while after rotation the cam disc 3 permits the spring controlled lever gear 3; to act on the drum so as to ra'se it with yielding elastic pressure against the tappet rods h and by means of the notches J in the uppermost matrices i to produce the desired selection of tappetrods 71,, so that only the rods it raised by the uppermost matrices effect a swinging down or disappearance of the corresponding panes b from the display surface, while the other panes remain unaffected and in their combination form the display matter standing up against the background, in correspondence with the selective design of these matrices.

play surface, say the letter E for the formation oi which the panes shown hatched in Figure 2 are suitable for example, then when the drum is raised the uppermost matrices i", i i P'P, a of the drum so act with their left hand pattern range, that all the panes b which do not take part in the formembers are If any inscription is required on the dis- Gil mation of the letter E, that is the panes eX- tending round the outline thereof, are caused to disappear into horizontal position by the action of the corresponding tappet rods, so that only panes directly forming the letter E remain standing in indicating position. This raising of the drum takes place when one cam of the disc 8 runs off the lever 20. On further rotation of the shaft 7" the second cam of the disc 8 engages the lever 39 and thus lowers the drum j. The pre viously raised tappet rods h descend by their own weight and while the drum is still held down by this cam, the grooved shifting cam a comes into action in order to move the drum axially through the lever m and to set the right hand pattern range of the uppermost matrices of the drum beneath the tappet rods it. Since this pattern range has a different form and arrangement from the left hand range, as soon as said cam of the disc 8 leaves the lever p and the drum is again raised, an alteration in the selection of tappet rods is effected which with suitable patterning will produce a different indication from the letter E. The first cam of the disc .9 again comes into action to lower the drum and eliace the matter on the display surface. lVhile the drum is thus held down, the groove shifting earn it also acts to return the drum axially, while the Geneva wheel mechanism hitherto out of action, rotates the drum in known manner through 60 by action of the single tooth 70 which has in the meantime arrived into position for operation, so that the matrices on the next side of the drum come into the working position, and the selection of the tappet rods h and panes 6 takes place again as described It will be seen that by means of the drum 7' a very large selection among the panes F) can be achieved and that after selection the picture or indication produced remains in the display position unchanged for atime, to be shown again unchanged, or to be changed according to whether the matrices on the drum have the same or different patternings. By changing the matrices on the drum while the a iparatus brought to rest which can be effected by uncoupling the pietures or iin'lications can be changed without limit.

What I elain'i is:

An automatic inscription and indication changing apparatus, comprising a large number of individually movable indicating elements within a display surface, an intermittently rotatable pattern drum, said drum carrying a plurality of gl'OllPS of pattern matrices having each a plurality of parallel pattern ranges, movable selectors between said pattern drum and said indicating elements, means to intermittently rotate the pattern drum for positioning one or other of its pattern matrice roups, means to axially shift said pattern drum so as to adjust the matrices of the positioned group thereof by one or other or their pattern ranges into operative position with respect to the selectors, and control means to bring said pat tern drum and selectors into cooperative relation with one another so as to cause in ac cordance with the operative design of the pattern drum a selection among said indicating elements for indicating purposes.

In witness whereof I have hereunto signed my name this 19th day of Nov-ember, 1926.
