"A NEW AND IMPROVED AUTOMATIC MODE OF DISPLAYING ADVERTISEMENTS.'
A communication from abroad by Louis Tampier, of Bordeaux, in the French
Republic.
This Invention consists in a new and improved automatic mode of displaying a
succession of advertisements so as to keep them continually moving before the eyes
of the public.
The following is the manner of displaying advertisements according to this In-
vention. Inside a box or frame or receptacle I place horizontally and at a suit-
able distance from each other two parallel cylinders held in bearings and in such a
manner as not to impede the action of two regulating rollers placed in front of
them at the top and bottom of the aforesaid box or frame. On the above cylinder
is affixed and coiled a long strip of paper, canvas, or other suitable material, trans-
parent or otherwise, on which are printed, painted, or produced by any known
process a series of advertisements. This strip of paper or canvas passes over the
regulating rollers aforesaid, which keep it always flat in front of the box or frame.
At each end of the cylinders is fixed a circular convex plate, the object of which is
to insure the regularity of working of the strip of paper or canvas aforesaid.
The above described cylinders are made to revolve by means of clock work,
weights, springs, air, steam, or other motive power by which a slow, quick, or
sudden, alternate, and intermittent motion may be given to them and to the strip
of paper or canvas which is made to coil or uncoil on or from the said cylinders.

"A NEW AND IMPROVED AUTOMATIC MODE OF DISPLAYING ADVERTISEMENTS."
A communication from abroad by Louis Tampier, of Bordeaux, in the French
Republic.
This Invention consists in a new and improved automatic mode of displaying a
succession of advertisements so as to keep them continually moving before the eyes
of the public.
The following is the manner of displaying advertisements according to this In-
vention. Inside a box or frame or recepetacle I place horizontally and at a suitable
distance from each other two parallel cylinders held in bearings and in such a
manner as not to impede the action of two regulating rollers placed in front of them
at the top and bottom of the aforesaid box or frame. On the above cylinders is
affixed and coiled a long strip of paper, canvas, or other suitable material, transparent
or otherwise, on which are printed, painted, or produced by any known process a
series of advertisements. This strip of paper or canvas passes over the regulating
rollers aforesaid, which keep it always flat in front of the box or frame. At each
end. of the cylinders is fixed a circular convex plate, the object of which is to insure
the regularity of working of the strip of paper or canvas aforesaid.
The above described cylinders are made to revolve by means of clockwork,
weights, springs, air, steam, or other motive power by which a slow, quick, or sudden,
alternate, and intermittent motion may be given to them and to the strip of paper
or canvas, which is made to coil or uncoil on or from the said cylinders.
And in order to explain this Invention more fully I will now proceed to describe
the means whereby it may be effected, reference being had to the illustrative Sheet
of Drawings accompanying these presents, and to the numeral letters of reference
marked thereon respectively as follows
Figure 1 is a front view partly in section; Figure 2, a sectional elevation through.
the line X, Y, of Figure 1, of the mode of displaying advertisements according to my
Invention.
A is a box or glass frame in which are placed two parallel cylinders B, B', held in
bearings C. Around these cylinders is coiled a long strip D of paper, canvas, or
other suitable material transparent or opaque on which are printed, pasted, painted,
or otherwise produced a series of advertisements. At each end of the cylinders
aforesaid is fixed a circular convex plate b, the object of which is to insure the
regularity of working of the strip of paper or canvas.
The said strip of paper or
canvas passes from the cylinders B, B, over two regulating rollers E, E', which are
placed in front of the box or frame A, as shown, to keep the said strip flat and at
the same distance from the front of the said box or glass frame.
The cylinders B, B', are put in motion through the wheels or pulleys F, F¹, by
clock work, weights, springs, air, steam, or other motive power which impart to them
a slow, quick, or sudden, alternate, successive, or intermittent motion. The strip of
paper or canvas D coils and uncoils on one or the other of the cylinders B, B¹, and
thus the advertisements are kept continually moving before the eyes of the public.
Having now described and set forth the nature of my said Invention, I would
remark in conclusion that what I claim as my Invention, and desire to secure by
the herein-before in part recited Letters Patent is, "The New and Improved
Automatic Mode of Displaying Advertisements" by means of a strip of paper, canvas,
or other suitable material, opaque or transparent, which is made to coil and uncoil
(by any known motive power) on and froin the cylinders B, B', and to pass over the

page_text: two regulating rollers E, El. The object of the said rollers being to keep the strip
of paper or canvas always flat and at the same distance from the front of the box or
-glass frame A..
In witness whereof, I; the said James Ledger, have hereunto set my hand
and seal, this Twenty-ninth day of May, in the year of our Lord One
thousand eight hundred and seventy-seven.
