Apparatus for Exhibiting Advertisements.
I, LEONARD LABATT, of 41 rue Cambon, Paris, in the Republic of France, do
hereby declare the nature of this invention to be as follows
--
The object of the present invention is a tablet for moveable advertisements. This
tablet is shown in the accompanying drawing, in which Figure 1 is a front view of
the tablet, the lower part of the front of which is removed in order to show the
internal mechanism.
Figure 2 is a side view of the tablet and Figure 3 is a view on a larger scale of
one of the shutters.
Figure 4 shows in perspective a lantern to which I apply my invention.
A is a case, of wood or other material, the upper part of which forms a tablet to
receive the moveable advertisements. The lower part of the case A receives the
driving mechanism; it consists of a clock-work movement B, which by means of the
connecting rod & gives a to and fro motion to a horizontal rack C. With this rack,
pinions P gear and govern the vertical axes T. These axes are mounted between the
upper part of the tablet and the fixed support s, which serves also as a guide to the
rack C. Upon the axes T are fitted little metallic frames or shutters R, intended to
receive letters, photographs &c.
the
Figure 3 shows one of these frames into which is introduced the letter L;
letter A, which is behind, is placed at the bottom of the tablet. It is easy to
understand the working of the apparatus; after having placed the desired letters in
the frames or shutters, the apparatus is wound up and at once commences to work,
the shutters fall alternately to the left and to the right. In Figure 1 they have fallen
to the left and show the word "Lunel ;" when they have fallen to the right they show
another word, and lastly the bottom of the tablet may bear an inscription or views
which are only visible while the shutters are passing from one position to the other.
It is easy to understand that I can also with this arrangement have tablets for
moveable advertisements in which I place any kind of light. In that case the slabs
of the shutters are by preference of glass.
Figure 1 shows a tablet intended to be suspended to a wall, the bottom of the
tablet being placed against the wall, but it may be necessary in some cases to fix it by
the end. Tablets with a double row of shutters can then be constructed. It suffices,
in point of fact, to place in the apparatus a double rack which governs the two rows
of pinions. In this latter case the motor is placed by preference in the end.
Figure 4 shows in perspective a lantern provided with two rows of shutters. It is
a matter of course that I can utilise any suitable electric or other motor to work the
rack, and that I can make the apparatus of any suitable size, and can give it any
shape which may appear preferable according to circumstances.

Apparatus for Exhibiting Advertisements.
I, LEONARD LABATT, of 41 rue Cambon, Paris, in the Republic of France, 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 object of the present invention is a tablet for moveable advertisements. This
tablet is shewn in the drawing left with the provisional Specification, in which
Figure 1 is a front view of the tablet, the lower part of the front of which is removed
in order to show the internal mechanism.
Figure 2 is a side view of the tablet and Figure 3 is a view on a larger scale of one
of the shutters.
Figure 4 shows in perspective a lantern to which I apply my invention.
A is a case, of wood or other material, the upper part of which forms a tablet to
receive the moveable advertisements. The lower part of the case A receives the
driving mechanism; it consists of a clock-work movement B, which by means of the
connecting rod b gives a to and fro motion to a horizontal rack C. With this rack
pinions P gear and govern the vertical axes T. These axes are mounted between the
upper part of the tablet and the fixed support s, which serves also as a guide to the
rack (Upon the axes T are fitted little metallic frames or shutters R, intended to
receive letters, photographs, &c.
Figure 3 shows one of these frames into which is introduced the letter L, the
-letter A, which is behind, is placed at the bottom of the tablet. It is easy to under-
stand the working of the apparatus, after having placed the desired letters in the
frames or shutters, the apparatus is wound up and at once cominences to work, the
shutters fall alternately to the left and to the right. In Figure 1 they have fallen to
the left and show the word "Lunel," when they have fallen to the right they show
another word, and lastly the bottom of the tablet may bear an inscription or views
which are only visible while the shutters are passing from one position to the other.
It is easy to understand that I can also with this arrangement have tablets for
moveable advertisements in which I place any kind of light. In that case the slabs
of the shutters are by preference of glass.
Figure 1 shows a tablet intended to be suspended to a wall, the bottom of the
tablet being placed against the wall, but it may be necessary in some cases to fix it by
the end. Tablets with a double row of shutters can then be constructed. It suffices,
in point of fact, to place in the apparatus a double rack which governs the two rows
of pinions. In this latter case the motor is placed by preference in the end.
Figure 4 shows in perspective a lantern provided with two rows of shutters. It is
a matter of course that I can utilise any suitable electric or other motor to work the
rack, and that I can make the apparatus of any suitable size, and can give it any
shape which may appear preferable according to circumstances.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The combination with a motor of moveable shutters worked by it enabling the
advertisements of the apparatus to be made to alternate.
2. The special arrangement of the shutters consisting of metallic or other frames
into which can be introduced slabs bearing the desired letters or inscriptions.
3. The combination with the tablet for moveable advertisements above described
and shown, of any suitable means of internal lighting.
All as I have described and shown in the accompanying drawing.
