COMPLETE SPECIFICATION.
A New or Improved Device for the Display of Advertisements and
the like.
I, REGINALD HADDAN, of the Firm of Herbert Haddan and Co., of
18, Buckingham Street, Strand, W.C. London, Patent Agent, do hereby declare
the nature of this invention a communication to me from abroad by the Firm of
Gebr. Stollwerck, Chocolate Manufacturers, of Cologne in the Empire of Germany,
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
This new or improved device is intended for use as a means for displaying
advertisements and it consists essentially of a central or rigid board or body and of
two outer movable boards or parts, which latter, by means of a clock-work or
otherwise, can be turned over the front of the central board or body and be lifted
off again respectively so that when both are folded thereover only one width of
board appears, thereupon after turning off one of the outer boards, its heretofore
hidden face and the back of the other board will be seen and lastly after turning
off the other outer board, three boards will become visible in width; thus by the
turning of the two outer boards 5 different spaces or surfaces in all will be rendered
visible.
The central board is fixed and arranged either upon a stand or as a hanging
device and serves at the same time for concealing the working mechanism.
The arrangement of this advertizing board allows of successively showing a
proportionately large number of different advertisements or separate sections
successively of a general announcement.
When skilfully made so that the working mechanism remains unseen, the board
will offer a peculiar and surprising effect and therefore constitutes a very effective
means of advertising.
This invention is illustrated in the annexed drawing, in which
Fig. 1 is a front view of the board in folded condition.
Fig. 2 a lateral view of Fig. 1.
Fig. 3 represents the board in front view, one outer portion being folded off the
central board.
Fig. 4 a lateral view of Fig. 3, and Fig. 5 a modification thereof.
Fig. 6 shows the board in completely opened condition in front view. Fig. 7 a
lateral view thereof.
Fig. 8 is a plan view.
Fig. 9 represents on a larger scale a portion of the central board with the
actuating mechanism, as seen from behind.
Fig. 10 is a lateral sectional view of Fig. 9, while Figs. 11 and 12 are detail
views.
a is the central and firmly fixed board or part, b and c are the two outer and
On the
movable portions, m is a clock-work arranged at the back of the part a.
arbor of this working mechanism two grooved discs and s are arranged, in the
grooves and s' of which respectively engage the rollers hand l' of the levers h, l,
pivotally connected at .. (See Figs. 9 and 10).
At the rear of the middle part a short shafts k, k, are journalled, one above and
one below, on each of which are fixed respectively the two levers t and g, of which
the former levers t by the medium of the connecting-rods h³ and respectively are

and c respectively.
When the arbor i rotates in the direction of the arrow (Fig. 9) the roller ¹ is
raised and by the aid of the lever mechanism and parts h, h³, t, k, g, z, the board b
is turned upward out of the position shown in Figs. 1 and 2 into that shown in
Figs. 3 and 4, whereupon the roller is guided in the concentric position of the
groove (see Fig. 11) and the part b¹ (b) held in its upright position.
During this movement of the lever, the roller is guided in the concentric
portion of the groove of the second disc s, until the projection forces the same
downward as is illustrated in Fig. 11 in dotted lines and in Fig. 12 in full lines.
In the latter figure for the sake of clearness the disc r is omitted and disc s
only is shown. On the downward movement of the roller , mechanism and
parts 1, 12, t, k, g, z, cause the board c to be turned out of the position shown in
Fig. 4 into that shown in Fig. 7, but as soon as the roller has passed the
projection the roller is raised again and the board or part c is moved upward
again into the position shown in Fig. 4. Then also the roller of the lever
will
re-enter the straight part of the groove r, the lever h, h³ rises again and the
portion falls back into its initial position (Fig. 2) whereupon the action is
recommenced as above described.
To provide an easy turning movement of the boards b, c, on their hinges y,
counter weights v are suitably provided on said hinges.
During this above described action 5 ad vertising surfaces of the three boards a, b, c,
are successively brought into view, which may be done as illustrated in Figs. 1, 3
and 6 in a very effective manner.
The middle part a may, as shown in Fig. 5, also be constructed so as to present
a hollow space which may be arranged so as to receive samples of merchandise.
This board may, instead of being arranged or hung up with the hinges of its
parts horizontal, also be arranged so that the portions b, c, turn upon vertical axes.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is ;-
1. A device for display of advertisements or the like consisting of three tablets
or the like a, b, c, in combination with mechanical gear adapted to fold the outer
tablets b, and c, over and from the tablet a substantially as and for the purpose set
forth.
2. The combination with the three tablets a, b, c, of the gear comprising the cam
discs r, s, a motor for said discs and means for transferring the movements of said
discs to the tablets b and c, respectively for the purpose set forth.
