APPARATUS .FOR DISPLAYING ADVERTISEMENTS.

Application filed May 15, 1925, Serial No. 30,486, and in France Kay 21, 1924. I

This invention relates to a process'of exhibition of texts or pictures, for advertising and similar purposes, by means of flat-display appliances with complete disappearance.

' sions, where the texts, etc., were caused to appear and disappear in a field of limited, invariable size, this being done by various suitable means. Owing to this feature, the public soon becomes accustomed to such devices, and a rapid decrease in their efliciency is the consequence.

On the other hand, in the process which forms the matter of this invention, the text or picture is displayed suddenly or gradually, thus causing, so to speak, a visual shock to the public,which commands at tention and excites the curiosity of the public; afterwhich the textor picture disappears entirely, so that the following reappearance will benefit by the same effect of suddenness and surprise. p

The apparatus used for performance of this displaying process substantially consists of a base, a movable body which can recede away from this base whilst remaining parallel with it, flexible walls, which can unroll or spread out between said base and said movable body, and a suitable mechanism that causes said movable body to move away from said base, thus displaying the flexible surfaces.

Various forms of execution of this invention are shown. in the accompanaying drawings, in which similar parts are always represented by the same respective reference numbers.

In Figs. 1 and 2 is shown a device with two display surfaces, latter being shown here in the displayed position. Figs. 3 audit are outside views of the same device. in the collapsed position. Fig. 5 refers to a de vice which operates on the same general lines, but where a number of flexible surfaces can be alternately displayed on both sides. Fig. 6 is a view in side elevation of the lower portion of the structure shown in Fig. 5, a part of the casing 1 being removed.

In these drawings, 1 is the base of the apparatus; 2 is the movable part or body. The relative motion of latter with respect to the base is effected by means of a set of hinged parallelograms, consisting of bars this base, whereas both parts will permit nently remain'parallelwith each other, because the pivots 5 and 6, which are fastened to the links 3 and 4, can slide freely within the slots 7 and 8 of both base and movable part. It will be readily understood that part 2 will move towards base 1 when pull- I ingapart the handles 3 and 4E and, reversely, will move away from said base when pulling together said handles.

In the Figures 1 to 4, the flexible walls or surfaces 9 and 10 are fastened by one of their ends to partQQand by their other ends to rolls 11 and 12, which are s0-called automatic rollers, that is, provided with springs (internal as a rule) said springs being so arranged as tocause the rolls to have a tendency to windup the correspondingflexible surfaces, I

Thus,the flexible surfaces which bear the advertising texts or pictures or the like,

'which are to be exhibited, can be displayed 'integrally'or partly, suddenly or gradually,

and at such intervals as will be found des1rable. at will of the operator who actuates the handles 3 and 4.

In the alternative form shown in Fig. 5, there are several flexible surfaces (four in the sketch) provided on each side of the parallelogram set. Said surfaces, 9 and 10*, are so arranged as to wind up on automatic rolls 11 and 12 the shafts of said rollers, numbered 13 and 14, are carried by cheeks 15 and 16, which in turn are seated on both ends of shafts 17 and 18. There are suitable notches 19 and 20 provided on the periphery of said cheeks 15 and 16, and the free or upper ends of the flexible surfaces are fitted with rails or rods 21 and 22, which can rest in said notches; said rods project outwards, over the edges of said cheeks. so as to permit them being gripped on both ends by hooks 23 and 24, which are pivoted to part 2 and fitted with springs 25 and 26, said springs being so arranged as to always maintain the hooks in the position shown on the drawing.

It is to be understood that each shaft 17 andl8 carries at each end a roll-carrying plate or check 15, and 16, and that these shafts extend across the base from end to end in a direction at right angles to the paper in Figure 5. The dotted lines ex tending upward on each side of Figure 5 indicate the'positions which the flexible bands would occupy when on exhibition.

Furthermore, each of the shafts 17 and 18 carries on one of its ends. a ratchet wheel 27. A pawl 28 pivotally supported upon a standard carrying the shaft 18 is engaged with the teeth of said wheel 27, by means of a spring 29. Said pinion 80 is mounted loose on the corresponding shaft 17 or 18, and meshes with a rack 31, which slides in a guide 32, and is so arranged that it is lowered by part 2 on completion of the downwards stroke of said part, and then pulled upwards by the spring 38.

The fixed base 1 is also provided with fingers or cams 34: and 35, which are arranged so as to cause the hooks 23 and 21 to release, when said cams strike the pins 36 and 37 of the hooks.

Operation.-Let us examine a complete cycle of operation, starting from theposition shown on Fig. 5; i. e., where there is one of the flexible surfaces dlsplayed on each side of the device. If the operator gives up exerting a pull on the handles, the automatic rolls will wind up the flexible surfaces,

so that part 2 will move towards base l As soon as the pins 36 and 37 strike the cams 34; and 35, the hooks 23 and 24 will release the ends of the rods 21 and 22, and said ends will fall into the notches 19 and of the cheeks 15 and 16. As soon as this is done, and during the last part of the downstroke of part 2, said part 2 strikes the rack 31, thus rotating the pinion's finally, the motion of the rack will cause the shafts 17 and 18 to revolve a quarter of a turn in the directions shown by the arrows (1., after which these shafts will be maintained by the pawls 28 in the position which corresponds to other rolls or flexible ad vertisements. At that time, the hooks 23 and Qlhave come back to their initial positions, so that'theywill grip the ends of the rods, and thus unwind and display a set of two new advertising surfaces, as soon as part 2 will, be operated upwards again.

lVhat we claim is:

1. Means for displaying advertisements and the like comprising two parallel spring rollers, lifting means locatedbetween said rollers, a body adapted to be raised by said lifting means, and flexible bands attached to saidrollers and to the two sides of said body whereby a balanced tensional resistance is produced during the simultaneous display of two advertisements.

2. Apparatus for displaying a number of different advertisements successively com prising a plurality of spring rollers mounted rotatably in parallel position, a flexible band on each, a lifting body, means for raising and lowering said body, means automatically actuated by movements of said body for rotating the mounting of said bands and automatic means on said body adapted to release and engage the ends of the different bands successively as said body is raised and lowered.

In testimony whereof we affix our signatures.
