Improvements in Means for Obtaining Rapid Changes of Wording or
Wordings, or Pictures, viz., in Changing the Presentation of One
Board or Sheet for Another, and applicable to Advertising
Purposes, and also generally.
We, JULES HIPPOLYTE CORTHESY, of 83, Newman Street, Oxford Street,
London, W., Printer and ELIAS BERNARD KOOPMAN, of 18 and 19, Great Wind-
mill Street, Shaftesbury Avenue, W., Managing Director, do hereby declare
the nature of this invention to be as follows:-
The purpose of this invention is to afford a means of rapid change of word.
ing or wordings or pictures by substituting the presentation of one for that of
another. To obtain this effect each board or sheet which is to contain one com-
plete presentation at a time is made of sections or of separate blades attached
to a frame and so arranged as to resemble a venetian blind.
Thus for any
number of different presentations just as many similarly composed boards or
sheets will be required. The boards or sheets are superposed or ranged in
facial succession, one backing the other, and as they may have all the same
number of sections or blades, said sections or blades are all equi-distant, and all
the corresponding sections or blades of the different boards or sheets have their
ends crossing longitudinally and oblically to the line of the frames,-over a
part of the face of their next or following sections or blades. Thus, for instance,
all sections or blades a cross over sections or blades b; sections or blades
cross over sections or blades c, and so on. And when, say sheet or board No. 2
is moved forward, the sections or blades appertaining to it will slide from their
hidden place to the front of the next sections or blades of the board or sheet
No. 1. In this wise the sections or blades of any board or sheet moving for-
ward will hide the sections of their next forward board or sheet and be exposed
in turn-if their front or preceding board or sheet sections or blades have been
withdrawn; and when any board or sheet is moved backward or its sections
or blades are withdrawn, the contrary effect will take place. The blades or
sections are so cut and attached to their frame as to afford great ease of motion
either to themselves or to those appertaining to other boards or sheets, and the
least possible amount of friction. When using two boards or sheets one of
them can be fixed and the other one be moveable, that is, the sections or blades
of the latter can travel longitudinally and oblically forward and backward
between the sections or blades of the fixed board or sheet, viz. expose their face
or hide behind the sections or blades of the fixed board or sheet. When three
boards or sheets are used one can be fixed and the two others moving to and fro,
independently of cach other, as described, and so on.

page_text: Any kind of motion can be used: clockwork, electric motors, etc.; the shaking,
the balancing motion of any vehicle, omnibus, train, boat, etc., will also be
effective, and can be applied.

Improvements in Means for Obtaining Rapid Changes of Wording or
Wordings, or Pictures, viz., in Changing the Presentation of One
Board or Sheet for Another, and applicable [to Advertising
Purposes, and also generally.}
- We, JULES HIPPOLYTE CORTHESY, of 83, Newman Street, Oxford Street,
London, W., Printer and ELIAS BERNARD KOOPMAN, of 18 and 19, Great Wind-
mill Street, Shaftesbury Avenue, W., 'Managing Director, do hereby declare
the nature of this invention and in what manner the same is to be performed
to be particularly described and ascertained in and by the following statement:-
The purpose of this invention is to afford a means of rapid change of wording
or wordings or pictures by substituting the presentation of one for that of
another.
The invention is illustrated in the accompanying drawings in which :-
Fig. 1 is a front view of the apparatus having part of the blades a removed..
Fig. 2 is a section through A, B Fig. 1.
Fig. 3 is an end view of Fig. 1.
To obtain this effect each board or sheet which is to contain one complete
presentation at a time is made of sections or of separate blades a, a¹, a²
attached to frames b, b1, b2 and so arranged as to resemble a venetian blind.
Thus for any number of different presentations just as many similarly con-
structed frames similar to b, 61, 63 having a series of sections or blades similar
to a, a¹, a attached thereto will be required.
Said frames are superposed or arranged in facial succession, one backing the
other, and as they may have all the same number of sections or blades, said
sections or blades are all equi-distant, and all the corresponding sections or
blades of the different frames have their ends crossing longitudinally and obli-
cally to the line of the frames 6 61 62 over a part of the face of their next or
following sections or blades. Thus for instance all sections or blades a cross
over sections of blades a¹, sections or blades a¹ cross over sections or blades a²
and so on.
And when say the frame 61 is moved forward in the direction of
the arrow marked thereon, the sections or blades a¹ appertaining thereto will slide
from their hidden place to the front of the next sections or blades a of the
frame b. The blades or sections are so cut and attached to their frame as to
afford great ease of motion either to themselves or to those appertaining to other
frames and the least possible amount of friction. When using two frames one
of them can be fixed and the other one be moveable that is the sections or
blades of the latter can travel longitudinally and oblically forward and back-
ward between the sections or blades of the fixed frame, viz. expose their face or
hide behind the sections or blades of the fixed frame. When three frames are
used one can be fixed and two others moving to and fro independently of each
other, as described and so on.
.
Any kind of mechanism can be used for actuating the apparatus such as

page_text: clockwork, electric motors or the like and the shaking vibration or balancing
motion of any vehicle, omnibus, train, boat or the like will also be effective and
can be applied.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
In advertising apparatus, a series of frames or bearings each having a series
of laths blades boards or the like of any suitable material attached thereto in
any suitable manner and so arranged as to resemble in appearance a venetian
blind said series of laths blades boards or the like of each frame or bearing con-
taining one complete advertisement representation picture or the like substan-
tially as herein before described with reference to the accompanying drawings.
