Improvements in Apparatus or Means for Displaying Pictorial or
other Advertisements.
I, OSCAR AUGUST BEREND, of Dunedin House, Basinghall Avenue, in the City of
London, Engineer, do hereby declare the nature of this invention (which has been
communicated to me from abroad by August Klumpp. of Munich, in the Empire of
Germany, Merchant,) and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement :-
This invention relates to ineans for displaying pictorial or other advertisements on
tablets which are capable of being intermittently moved so as to expose to view in
succession advertisements of different kinds. In arrangements hitherto employed
for this purpose where several tablets with advertisements thereon have been dis-
played one above another, or side by side, spaces of greater or less width have
necessarily been left between the ends or edges of the adjacent tablets according to
the size of the tablets, owing to the said tablets being of the same size or width as
the prisons or carriers over which the tablets are caused to travel and consequently a
non-continuous or broken display surface has been produced. The object of this
invention is to provide means whereby a practically continuous or unbroken display
surface is produced by a combination of tablets so as to produce a complete picture
or device and which also admits of the picture or character of the advertisements
being intermittently changed. I will describe the invention with reference to the
accompanying drawings of which Figures 1 and 2 are views of arrangements of
apparatus according to this invention. Figure 3 is a front elevation Figure 4 a plan
and Figure 5 a vertical section of a modified arrangement. In Figures 1 and 2 are
represented three sets of tablets & and their carriers arranged one above another
which tablets may be made of any suitable material such for instance as sheet metal,
glass, card-board, wood, or the like, on which the advertisements or parts to form a
picture are provided. These tablets are rivetted or otherwise fixed to endless chains,
bands or the like passing round carriers c mounted on shafts or spindles d
arranged at suitable distances apart. In the drawings I have shewn the carriers as
being rectangular, this being the simplest form, but they may be circular, triangular
or of any other suitable shape, and any desired number of sets of tablets a may be
combined to form a display surface. The tablets a are of such width or length with
reference to the distance between two sets of carriers c that when the said tablets are
in their displayed position the edges of the tablets will touch or nearly touch one
another so that visible spaces between the tablets are avoided and by this improved
arrangement a larger display surface may be provided with a less number of carriers
and tablets than heretofore. The carriers c round which the endless bands or chains b
pass may consist of hollow or solid bodies, or they may be open frames, or they may
be discs as shewn in Figure 2 of the drawings and they may be rotated or oscillated

page_text: by any suitable means so as to intermittently change the position of the tablets to
display different advertisements or pictures.
Instead of securing the tablets to endless bands or chains or the like as herein before
described the said tablets may be pivotted to the diametrically opposite sides or edges
of pairs of discs or carriers c as shewn in Figures 3, 4, and 5 and each tablet be
provided on its two faces with different advertisements or designs. Each pair of
dises or carriers may be caused to rotate or oscillate on their axes d separately or
several pairs of discs or carriers may be operated simultaneously the tablets being of
such size that when several sets are arranged side by side or one above another the
adjacent edges of the several tablets when brought into position to display the
advertisements thereon, will touch or nearly touch one another so as to form a
practically continuous surface. By this arrangement each pair of tablets may be
turned on their pivots a² at each half rotation of the carriers or discs whereby four
different advertisements can be intermittently displayed by each pair of tablets.
I now describe mechanism by which the rotation of the tablets on their pivots may be
performed but this mechanism I do not claim. The shafts d, as shewn in Figures 3 and 5,
are arranged one above another at a suitable distance apart, and fired on the inner ends
of the said shafts are carriers c for the tablets a. Each tablet has at its ends pivots a²,
which turn in bearing on the edges of the pair of carriers to which the tablet
is fitted. Each pair of carriers has bearings for two tablets and the pivots a³,
at one end of each tablet, on which the said tablets turn, are rectangular at their ends
and enter grooves or guides c2 in stationary plates d². Fust on each of the square
ended pivots is a pinion e caused to engage with rack teeth projecting from the plates d²
so as to impart to each tablet motion of partial rotation on its pivots. When it is
desired to remove from view one set of tablets and to bring a fresh set of tablets into
view, the shafts d, and with them the carriers are rotated, whereupon the pinions on
the pivots of the tablets moving out of view, will engage with the rack teeth f on the
stationary plates d², whereby the said tablets will be caused to turn one quarter of a
revolution, and the pinions on the pivots of the tablets being brought into view,
will engage with the rack teeth f and be turned thereby to the extent of one quarter of a
revolution.
By this arrangement each time the tablets are brought into display position the side
of each tablet then exposed to view will be the reverse of that last exposed.
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. In apparatus for displaying pictorial-or-other-advertisements,-the-combination
of an endless-chain of tablets provided with advertisements-to-be--displayed-of
rotary-or-oscillatory carriers round-which-the-chain of tablets pass, the diameter or
width-of-the-earriers being less than the--width-of-the-tablets, substantially--as
hereinbefore described.
2.1. In apparatus for displaying pictorial or other advertisements the combination
of two or more endless chains arranged in parallelism and having rigidly fixed
thereon of tablets provided with advertisements or pictures to be displayed, rotary or
oscillatory carriers round which the endless chains of carrying the tablets pass, the
said carriers being of less width or diameter than the width of the tablets and
arranged at such distance apart that when the tablets are moved into position to dis-
play the advertisements or pictures thereon the contiguous edges of the tablets are so
near together as to prevent visible spaces between the tablets and present to view
a practically unbroken or continuous display surface, substantially as hereinbefore
described.
3. In-apparatus for displaying pictorial--or-other-advertisements, tablets--and
pivotted-to-diametrically opposite sides-of-rotary-or-oscillatory carriers so that by
rotating-or-oscillatory the--earriers; and the tablets on-their-axes--or--pivots--the
advertisement on both sides of the tablets enn-be-intermittently displayed,
substantially-as-hereinbefore-described.

page_text: 4.2. In apparatus for displaying pictorial or other advertisements, the combination
of two or more pairs or sets of tablets, provided on both sides with advertisements to
be displayed and rotary or oscillatory carriers to diametrically opposite sides of which
the tablets are pivotted and which are of less width than the width of the tablets and
arranged at such a distance apart that when the tablets on the several carriers are
rotated or oscillated to bring the opposite sides of the tablets alternately into position
to display the advertisement thereon the contiguous edges of the said tablets are so
close together as to prevent visible spaces between them and present to view a
practically continuous or unbroken display surface, substantially as hereinbefore
described.
