Improvements in Apparatus for Advertising Purposes.
I, JOHN WARRICK, of St. Mary's Butts, Reading, Cycle Manufacturer, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following state-
ment:-
This invention relates to improvements in the construction of apparatus for
advertising purposes and its object is to provide an arrangement which will dis-
play moving advertisements in an attractive manner.
The apparatus is adapted for use with carrier cycles, omnibuses, tramcars, rail-
way carriages and other vehicles. It is also applicable for display in shop windows,
on hoardings, or in any other suitable position.
I purpose displaying the advertisements in a suitably formed case having
windows and arranged either inside or outside of any kind of vehicles: and
mounted or attached in such a way that they can be seen either from the outside
or inside or both as desired.
The advertisements are arranged and displayed upon sheets of paper or other
suitable material and wound on suitable drums or rollers provided with conical
flanges or small guiding rollers. These sheets are adapted to move in a vertical,
horizontal or other required direction either independently or synchronously, and
to appear at different windows.
The apparatus I propose to employ winds up the advertisements at regular
intervals so as to bring a fresh advertisement before the notice of the public at
every operation. The advertisements are moved rapidly into their new position
and are then held stationary until the predetermined time has elapsed when they
are again changed. The apparatus also provides a reversing mechanism which
when the advertisements have been completely wound in one direction will
automatically change the direction bringing the advertisements successively before
the window in a reversed order.
In order that the invention may be more clearly understood, reference is had to
the accompanying drawings, in which Fig. 1 is an elevation of a cycle provided
with my improved advertising case, Fig. 2 is a section of the case and Fig. 3 a
sectional plan of the same, Fig. 4 is a side elevation of the mechanism I
propose
to employ and Fig. 5 is a plan of the same, and Fig. 6 an end elevation, and Fig. 7
is a detail view showing part of the winding device.
As shown in Figs. 1, 2, and 3, the case A is provided preferably on each side
with the windows a and a', a pair of the latter being employed placed above the
former and of smaller dimensions. Fig. 1 shows the case carried on the tricycle B
and supported in the usual manner between the wheels. The advertisements are
displayed on the sheets C and C¹ the sheet C extending behind the window a and C₁
behind the window a¹. C is wound over the rollers or drums D, these drums
being placed horizontally so as to wind the sheet up or down. The sheet C¹ con-
sists of a narrow strip extending round the top of the case, and wound upon the
drums D passing over the rollers D2 at the corners of the case. The mechanism
for operating the advertisements is shown more fully in Figs. 4 to 7, and consists
of a driving axlo E carrying discs F. The spindle or axle E is driven by the

page_text: pulley e or by the train of toothed wheels e¹ the motion being derived from the
driving mechanism of the cycle or vehicle wheels or from any other suitable
mechanism when displayed in shop windows or other position.
The drum D on which the advertising sheets are wound is provided with the
central spindle d on which the bevel wheel d¹ is fitted. The spindle is turned 5
from one of the discs F by means of the spindle G having the bevel wheel gear-
ing into d. On the end of this spindle the toothed wheel g¹ is fitted which is
adapted to gear with the quadrant rack f on the face of each of the discs F. This
rack is concentric with the disc and is shown as extending for about one quarter
of a circle, but it may be made of any suitable length. The wheel gl engages with 1
one rack only at a time, the distance between the discs F being slightly greater
than the diameter of the wheel. The spindle G is supported in the carriage H
the latter being fitted on top of the support J, which may consist of a block of wood
or a metal frame placed on the bottom of the case A, or on any other suitable base.
The carriage H is pivoted at h close to the bevel gearing, and is adapted to turn
through a slight angle, the angle being so small that it will not interfere with the
gearing. It is provided with the slot h¹ and the screw j passes through the slot
screwing into the support J. The slot allows of the slight angular motion required
while at the same time it keeps the carriage in position for gearing purposes.
In order to change the position of the spindle, and consequently to reverse the
motion, an automatic reversing device is employed, consisting of the toothed
wheel K placed below the shaft E. The latter is furnished with a small wheel L
having the tooth adapted to engage with the teeth of the wheel K. As the axle
and disc revolve, this tooth causes the wheel K to turn for a short distance at
each revolution, bringing into action the cam or raised surface which extends
for about half its circumference. The carriage H is formed with the arm or exten-
sion 2 which projects at an angle and bears against the surface of the wheel K.
On the latter revolving the cam surface is brought round to the end of the exten-
sion and pushes it to one side, moving the carriage and causing the small toothed
wheel g¹ to engage with the rack on the second disc. The cam surface keeps it in
this position for the remaining half of the revolution of the toothed wheel K.
To cause the carriage to return when released by the cam, the spring 3 is
employed carried by the support h. This spring bears against the carriage, and
brings it when released towards the first disc as shown in Fig. 5, so that it
returns to this position.
To prevent the drum D turning except when operated by the gearing, it is pro-
vided with a small disc or extension in the side of which a notch is formed.
In this notch the pawl or lever M engages, the other end extending as shown in
Fig. 4 under one of the discs F. This disc is provided with the cam surface f¹
on its circumference equal in angular length to the rack f. This cam is placed so
that as the disc revolves it comes into action and presses upon the end of the
lever M. This raises the pawl or catch from the notch and releases the drum.
The cam is placed so that the drum is released just before the rack f reaches the
toothed wheel g¹. Immediately the rack has passed the wheel the cam releases the
pawl and the spring m causes it to engage again in the notch, the parts being
arranged so that the notch comes into the proper position after each operation.
On the end of the spindle d a second bevel wheel dis placed engaging with the
wheel N carried on the vertical spindle n. This vertical spindle as shown in
Fig. 2 operates the upper part of the mechanism carrying one of the drums D¹,
so that both advertisement sheets are worked simultaneously.
The apparatus already described, moves the advertisements only in the one
direction, and in order to take up the slack and to wind up the sheets in the
opposite direction, the arrangement shown in Fig. 7 is employed, in combination
with the reverse movement described. This consists simply of a spiral spring O
carried in the case o and provided with the intermediate wheels o¹ connected with
the roller or drum D. The spring is wound up when the advertisement sheet is
unwound from the roller, and the force of the spring keeps the sheet taut and also

page_text: winds it up in the opposite direction when it is unwound by the mechanism before
described, which then serves merely to unwind the sheet from the roller to which
it is connected.
This clockwork mechanism may also be used to drive the spindle E. The
position of the case is shown in Figs. 2 and 3.
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:-
