ADVERTISING DEVICE.

Application filed March 20, 1928.

To all whom it may concern.

Be it known that I, JoHANNns DINGEDAHL, a citizen of Germany, residing at Hamburg, Germany, have invented certain new and useful Improvements in Advertising Devices, of which the following is a specification.

This invention relates to display or advertising devices and in particular to signs, the characters or figures of display being capable of constant change whereby a plurality of lines of writing or pictures or data can be changed simultaneously.

An object of the invention is to provide a means whereby the displayed advertising signs will be used over again indefinitely and automatically without any attention on the part of the person using the device.

A further object is to provide independent sign members or plates which are brought to position singly and with a minimum of effort on the part of the actuating mechanism.

Referring to the accompanying drawings, wherein one embodiment of my invention is illustrated 1 is a face view of a sign board or box which is provided with openings through which the signs are displayed;

Fig. 2 is a side elevation in section taken on line 22 of Fig. 1 showing the operating mechanism in the interior of the device;

' Fig. 3 is a side elevation similar to Fig. 2, the mechanism being shown in sign chang ing position; and

Fig. 4C is a rear elevation of my improved device showing the location of the various parts of the operating mechanism.

Referring to the drawings in detail, wherein a casing is shown (a) denotes the front thereof which is provided with a series of aligned openings (6) disposed in rows to form sights through which may be seen suitable words or pictures used in advertising. The casing is divided into compartments by the vertical walls (0) which are disposed between the openings (b), each of the vertical compartments containing mechanism to display and change the sign placards operating before the openings (1)) of that particular compartment. Through V the bottom of the casing extends a shaft (0?) which is rotated in alternate direction by any suitable means not shown such as a motor and alternating clutch.

the necessary Serial No. 626,330.

Extending substantially the length of the compartments and on both sides thereof are disposed guide rails, the front one (6) and the rear one (f), upon the former of which is slidably mounted the spaced hooks (g) and on the latter of which is also slidahly mounted the spaced hooks (h).

The hooks (g) which may be termed the displacing hooks are connected by the hook connectors (i) and the rear hooks (72 or replacing hooks are connected by the connectors (j). These connectors act as spacers and keep the hooks a given distance apart in their sliding movements on the rails.

The lower hooks (h) and (g) are connected by sprocket or like chains which pass over the sprocket wheels (72) which are fixed to the shaft (d) which passes through the compartments, and also over idlers (0). The upper hooks (it) and (g) are also connected by cables which pass over the rollers (Z) in the top of the compartment, it

being understood that there are two sets of hooks and their allied parts, one on each side of each compartment.

On the compartment walls there are dis posed placard holding rails, the rails (p) sloping forwardly and ending adjacent the upper edge of the display openings (6), and the rails (39) sloping rearwardly and being located adjacent the lower edge of the display openings (6). The rails (p) and (19) are provided with hooked or upturned ends (g), respectively on their forward and rear ends for a purpose later to be disclosed.

The placards on which may be printed letters as shown in Fig. 1 or pictures or any suitable marking, are, we will say for illustration, supported one behind the other on the rails (p), the placards having at their upper opposite corners rail engaging studs (8) which are hooked at their outer ends downwardly to prevent sidewise movement of the placards. These studs rest on the tops of rails (g0) and slide thereon. The forward placards on rail (p) are in display position, see Fig. 2, and when the hooks (9) move upwardly they engage the studs (8) and carry the placards up off the rails. The hooks slope forwardly and the hooked ends (9) of the rails (72) are so located that the inner ends of the hooks (g) just engage the studs (8) of the forward placard (r) and when the studs clear the hdoked ends (g) they slide down the The hooks and when the latter have a reverse movement the studs (8) will pass the rails 0) and allow the placards to be carried down until their lower edges rest in the open backed receptacles see Figs. 2 and 3, at which time they will tall backward upon a further downward movement ofthe hooks (5/), the studs (8) at this time coming to rest a 'nst the rear hooked portions of the reairardly sloping rails (p). receptacles (if) are open at the back and are in'ovideiil n 'th inclined bottoms (7 so that the placards when PlflCQtlil'lQIT-Zll'l will fall ba l; thri'iugh the rear openings and their upper ends will rest the rear 01" the rails (p). The receptacles-are disposed at the proper rli ce. below the forward edge of the rails (72) so that when the placards touch the bottom thereof, the hooks upon a further downward movement wil disengage the said placards and allow the same to tall rcarwardly against the bot tom oi" thereceptacle so that their studs (3) engage the rear-most portion of the rails (p) at which noint they will be in position to he suce vely engaged by the hooks (ii) to he subsequently redisplayed. It will be seen there ore ll at the inclined bottom of the receptacles supports the placards on the rails (32) in position to be enin the rear are mov up, so it "Yb a he rear or neari l5 ails (p) and carry t *lacard up. the hoo {S (h) ar also to :dly sloping and the studs are en, u so to remove only one placard which is then carried up on the hooks (Ii) until the studs are engaged and pushed back on the hooks by the cuiwed rear ends oi the railsip) to pass the same after which the studs (a) slide Forward on the hooks (72 and. upon a dew ward or reverse movem t of the same the (is are onwed by the rails and the p. rd sus- 'eliy in position to slide down 0) until al 1. acards beit are used, at 1 ch time it are i'l the open o for display. lhis is continent and t am. mil; her matter a compinto opening-i. it
