page_text: I, WILLIAM BLAKER, of 213, Western Road, Brighton, Manufacturer, do
hereby declare the nature of this invention to be as follows-
This invention refers to a special form of rotating or automatic advertising
device suitable for use in vehicles or shops, or like purposes, in which rollers
are caused to rotate in a case or frame of ornamental design, such rollers bear-
ing announcements or advertisements, pictorial or otherwise.
The rotating rollers may be horizontal or vertical.
A special clockwork mechanism actuated by a coiled spring is employed to
drive same and can be arranged to run for a week or less without rewinding.
This mechanism contains a series of geared wheels and spindles so arranged
as to effect an intermittent action of the advertising rollers, with clutches to
prevent backlash and detents to control motion as required.
A gong can be added to draw attention to the device when the action is about
to take place.
The device can be made in various sizes as for instance, large for railway cars
and small for cabs or light vehicles.

I, WILLIAM BLAKER, of 213, Western Road, Brighton, Manufacturer, 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 refers to a special form of rotary or automatic advertising
device suitable for use in vehicles or shops, or like purposes, in which one or
more rollers are caused to rotate in a case or frame of ornamental design, such
rollers bearing announcements or advertisements, pictorial or otherwise.
The rotating rollers may be horizontal or vertical. A special clockwork
mechanism actuated by a coiled spring is employed to drive same and can be
arranged to run for a week or less without rewinding.
This mechanism contains a series of geared wheels and spindles so arranged

prevent backlash and detents to control motion as required. A gong can be
added to draw attention to the device when the action is about to take place.
The device can be made in various sizes as for instance, large for railway cars,
and small for cabs and light vehicles.
I will now describe my invention with reference to the accompanying draw-
ings, in which,
Fig. 1 shews a front elevation of the advertising device with two rollers.
one vertical and one horizontal combined with an ornamental cabinet.
Fig. 2 shews an enlarged sectional elevation of the two advertising rollers
and also shews the method of driving them.
Fig. 3 shews a transverse section of the horizontal roller and the casing in
which it rotates.
Fig. 4 shews the clockwork motor.
Fig. 5 shows an end elevation of the controlling mechanism of the motor.
a is an ornamental cabinet for shewing goods and the like, in the upper por-
tion of which are arranged two rollers, b, c on which various advertisements
are displayed. is a horizontal roller which is caused to make an intermittent
partial rotation under the control of the clockwork motor d, Fig. 4, thereby
changing the advertisements. As shewn in Figs. 2 and 3 the roller b consists
of a light hollow drum, the advertisements being fastened on its exterior sur-
face. The drum is mounted on suitable bearings e, f, Fig. 2. The bearing
is a continuation of the central spindle of the motor, and same is fitted with
a crank e¹ the crank pin on the end of which passes through one end of the
drum b. thereby causing it to rotate with the central spindle e.
e
The bearing is hinged at f' to allow the roller to be taken out and
changed.
The above described roller is mounted behind the ornamental front the
advertisements, being seen through the opening g¹, h is a casing (Figs. 2 and 3)
to protect the roller b and the motor d. The mechanism of the clockwork
motor is as follows:-
Referring to Fig. 4 i is an ordinary form of escapement causing the toothed
pinion to rotate, which by a train of gear wheels causes the rotation of the
star wheel j, k. Figs. 4 and 5, is a spring finger mounted on the arbor
which engages each tooth of the star wheel j in turn, thereby preventing the
rotation of the arbor k¹ till the star wheel turns sufficiently to allow the finger k
to clear the tooth. When this happens the arbor ¹ makes one revolution and
is stopped when the finger catches again in the next tooth of the star wheel.
is a pinion on the arbor which engages a spur wheel which rotates the
central spindle e of the motor, and causes the rotation of the pinion m through
the idle wheel. The motor shewn is driven by a spring in the usual way.
Referring to Fig. 2 m is a toothed pinion rotated as above described mounted
on the end of a horizontal shaft m¹. The other end of the shaft is fitted with
a helical spring n bent to a quadrant shape, and is attached to a vertical shaft o
which forms the axis of the vertical advertising roller c. o is a bearing for
shaft o.
The roller c is similar in construction to roller b, and is provided at its upper
end with ratchet teeth p which engage with a spring detent pl to prevent back-
ward movement. The roller b may be provided with a similar fitting for the
same purpose. The rollers may be caused to rotate at the same speed or one
may rotate faster than the other.
7 is a gong shewn in dotted lines, which may be caused to ring by any simple
device operated by the clockwork motor at the time when the rollers b, c, are
rotated to attract notice to the advertisements.
The construction and attachment of the method of connecting same to rollers
and the mode of mounting said rollers have been carefully studied and experi-
mented on with a view to withstand the vibration of a vehicle moving over a

this difficulty and will be found to work properly in any vehicle whether in
motion or not and moreover can be fixed to the vehicle in any position.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
1. An advertising device for vehicles shops hotels and like places consisting
of one or more rollers arranged horizontally vertically or as preferred on the
exterior surfaces of which advertisements are displayed, said rollers being caused
to rotate intermittently by means of a clockwork motor said motor can also be
arranged to ring a bell to attract notice if desired. The above described
mechanism being mounted in and on an ornamental cabinet or other suitable
frame substantially as described and set forth.
2. In an advertising device for vehicles shops hotels and like places the special
clockwork motor as described for causing rollers to rotate intermittently and
ring a bell or gong at the time of changing the advertisements, substantially
as described and set forth.
3. In an advertising device for vehicles shops hotels and like places the com-
bination of the means as described for preventing backward motion of the
advertising rollers, with the horizontal shaft m, and flexible angle coupling
formed by the spring shewn, for driving the vertical shaft substantially as
described and set forth.
4. In an advertising device for vehicles and like purposes the special con-
struction and arrangement of parts whereby the said device will withstand the
vibration of a vehicle in motion without injury or stoppage of the mechanism
and moreover can be fixed to said vehicle in any desired position, as herein
described and set forth.
