I LOUIS TAMPIER of the Consulat General de Turquie, Bordeaux, in the Republic of
France, do hereby declare the nature of this invention to be as follows :-
:-
This Invention relates to improvements in apparatus for exhibiting a series of public
announcements or advertisements which are thereby displayed and withdrawn from
public view in succession and in an intermittently continuous manner.
The apparatus, which may be actuated by clockwork, electricity, compressed air,
hydraulic power, the wheels of vehicles, the engine of a steam boat or other prime
mover, consists essentially of mechanism whereby the band of paper or other material
bearing the advertisements or announcements is moved either with an intermittent or
a constant motion and whereby such motion is automatically reversed when the last
advertisement or announcement of the series is reached so that the display of such
announcements etc, will go on uninterruptedly.
This mechanism comprises for each band a pair of holding rollers upon which the
two ends of the band are secured and coiled, each roller acting alternately as a take-up
roller and as a let-off roller, the functions of the rollers being changed as the direction
of motion of the band is reversed.
The holding rollers are connected with the actuating mechanism through the inter-
vention of ratchet and pawl gear and adjustable friction springs, so as to cause the
direction of motion of the holding rollers to be reversed at the proper times in order
to reverse the travel of the band, motion being communicated to these rollers through
an endless chain running in one direction, said chain being driven from the main
shaft and acting on the said rollers through the ratchet and friction gear above
mentioned. The rollers are also provided with retaining pawls and friction springs.

page_text: These rollers and suitable guide rollers over which the band passes are mounted in
a case or frame having a flanged opening at the front, past which the paper band is
carried in its passage round the guide rollers.
Two or more such apparatus may be mounted in the same case and exhibit two, or
more strips at the same or different apertures and may be made to impart to the strips,
similar or different motions.
The paper or other strip may be transparent or otherwise and may have a mirror or
a light behind it to increase the attractiveness of its appearance.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Exhibiting Public Announcements
or Advertisements.
I LOUIS TAMPIER of the Consulat Général de Turquie, Bordeaux, 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 :-
This Invention relates to apparatus for exhibiting series of public announcements or
advertisements carried by a band which is caused to travel past an opening for the
purpose of exhibiting the advertisements etc, in succession; and the Invention consists
essentially of mechanism whereby an intermittent or a continuous motion is imparted
to the band and whereby such motion is automatically reversed at the required times
in order that the display of the announcements etc, shall be continued uninterruptedly.
This mechanism comprises rollers acting alternately as "take-up" and "let-off" rollers
for the band and mechanism hereafter described, whereby the direction of their motion
is automatically reversed at the proper times, in order to reverse the travel of the
band. Two or more such bands may be exhibited in the same case, and may receive
similar or different motions.
Reference is to be had to the accompanying drawings forming a part of this
Specification, which represent an apparatus comprising two bands, one receiving
continuous and the other intermittent motion. Figure 1 is a front elevation of the
mechanism, the front of the casing being removed and portions of the bands being
broken away to shew the mechanism. Figure 2 is a side elevation (the side of the
case being removed) shewing the chain gear of both bands, and the escapement

page_text: controlling the intermittently moving band. Figure 3 is a similar elevation of the
opposite side shewing the holding and guide rollers, the position of the bands thereon,
and the driving mechanism for the continuously moving band Figure 4 is a front
view and figures 5 and 6 are side views of the clockwork. Figures 7 to 14 shew
details hereinafter referred to.
The same letters of reference indicate the same parts in all the figures.
The power by which the actuating mechanism of each band is driven is preferably
a spring barrel, but any other available prime mover may be employed.
A Aare the two bands receiving the one continuous and the other intermittent
motion respectively. Their ends are attached to and wound on pairs of rollers a a, a* a*
respectively, the bands passing over intermediate guide rollers and the portions of
the bands distended between the guide rollers being exhibited at openings in the case
within which the mechanism is contained. Certain of the guide rollers act also as
driving rollers for the bands, and for this purpose they receive a positive motion.
B B are the endless chains by which the two sets of rollers for the bands A A* are
respectively actuated. C is the driving mechanism for the band A, and Cx the
mechanism for the band Ax.
The band, A attached to and wound on rollers a a, as above described, passes over
or round guide rollers d, e, f, as shewn in figure 3, whereof the roller receives
motion from the clockwork C and transmits it through endless chain B to the rollers a a.
This roller is roughened at the middle, in order that it may assist in driving the
band which is pressed against the roughened part by a soft roller g carried by a
spring. The clockwork consists of a spring barrel and train of wheels and pinions
controlled by a fly h, the wheel of the train being in gear with a pinion fl fast on
the end of the roller f. Upon the shaft of wheel i are two loose pinions in gear
with the wheel m on the second motion shaft the one k gearing directly therewith and
the other gearing indirectly through pinions m¹n on a counter shaft o. Between
these pinions the shaft of the wheel i is squared, and carries a clutch formed of arms
carrying pins p, one or other of which comes into the path of an arm k¹ or fixed to
the pinions whereby the shaft of wheel i is rotated in one or other direction, as
the case may be. The clutch p is slid along the shaft to throw it into gear with one
or other of the pinions and produce the desired reversal of the motion by a cam
(whose development is shewn in figure 14) acting on the pin r of a lever to which
is jointed a sliding rod s carrying a fork s¹ embracing the grooved boss of the clutch.
The cam has a ratchet toothed periphery and is driven by a ratchet pinion q' on the
second motion shaft, the object of this form of gear being to permit of the position of
the cam being adjusted to suit the position of the band, which is done when the
pinion is in such position that its teeth do not gear with the teeth on the cam.
The chain B runs on a chain-wheel fast on the other end of roller and gears
with similar chain wheels c on the axles of rollers a. is a guide wheel. Each
wheel c runs loose between collars on the boss, of a ratchet wheel with which engages
a pawl e carried by the wheel c. The ratchets are made friction tight on the axle of
the roller a by a spiral spring a compressed between the end of the roller a and the
boss of the ratchet wheel which is held in position by a cross-pin. At the opposite
end of each roller is another ratchet wheely made friction tight by a spiral spring y
compressed between it and the end of the roller, a pawl y mounted on a stationary
support engaging with the ratchet wheel.
"
The parts of the clockwork C* which are similar to those of clockwork Care
distinguished by the same letters with the addition of an asterisk and need not be.
again described. The wheel ¹× is however in this instance a chain wheel, and drives
the chain B* and the action of the clockwork C is controlled by an escapement
actuated by the clockwork C, through a shaft which is rocked periodically by a
ratchet toothed pinion on the second motion shaft of clockwork acting on an
arm fixed to the shaft. The escapement consists of a spring catch a pivoted to an
arm fixed to shaft and engaging with a pin w² fixed to wheel ix, and of a second
catch which comes in the path of the fly *. By the motion of shaft e, the catch.w
is first removed from the path of pin , the armi e meanwhile standing in the path
2

page_text: of the fly *. On the arm v² falling off the point of a tooth of pinion o³, the arm a
is withdrawn also, at the same time that catch again comes in the path of pin 2
whereby the clockwork Cx is permitted to run until the wheel has made one
revolution when it is again arrested.
The chain B gears with chain wheels ex connected with the axles of the rollers a by
ratchet and friction gear similar to that before described. The chain also gears with
a pinion fast on the end of the roller which is, in this instance, the upper guide
roller of the band.
The roller a which is for the time being acting as the "take up" roller for the
band, is driven through the ratchet and friction gear at the driving end of said
roller, the gear at the other end thereof then being inoperative and the necessary
tension is applied to the band by the ratchet and friction gear at the opposite end of
the other roller a (the "let off" roller for the time being) acting as a brake for the said
roller, the gear at the driving end of the last mentioned roller being then inoperative,
and conversely when the direction of motion of the band is changed The object of
using friction gear between the driving chain wheels and the rollers a is to prevent
overwinding of the band, and to compensate for the varying diameter on which the
band is wound.
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 ;-
1. In an apparatus for the purpose specified, the combination of a band having its
ends attached to and wound on holding rollers acting alternately as
"take up
and
"let off" rollers for the band and of mechanism substantially as shewn and described,
whereby the said rollers and band are driven and whereby the direction of motion of
the band is periodically reversed, substantially as set forth.
2. In an apparatus for the purpose specified. in which a band is attached to and
wound on holding rollers acting alternately as take up and let off rollers the
intervention between the endless chain driving gear and the said rollers of ratchet
and friction driving gear substantially as and for the purpose specified, and the
combination therewith at the opposite ends of the rollers of ratchet and friction brake
gear, the driving gear of the take up roller and the brake gear of the let-off roller
only acting at one time, substantially as specified.
3. In an apparatus for the purpose specified comprising two bands driven the one
continuously and the other intermittently by separate actuating and reversing
mechanisms as described the combination of the two mechanisms with an escapement
actuated by the one mechanism and controlling the other mechanism, substantially as
specific.
4. The combination and arrangement of parts constituting the improved automatic
advertising apparatus, substantially as specified.
