PROVISIONAL SPECIFICATION.
Improvements in and connected with the Displaying of
Advertisements.
I, ALBERT EDWARD RODGERS, of 64 Mark Lane, in the City of London,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in means for displaying advertisements.
by giving motion to frames, cases and the like of suitable design and shape,.
containing the advertisements, by the use of electricity from primary or secondary
batteries or other generators in such a manner that by merely moving any object
(such as a door) in a building an electric circuit will be completed by a suitable
arrangement of mechanism and cause the case or frame to automatically move in
various ways and thereby display the advertisements consecutively or otherwise.

Improvements in and connected with the Displaying of
Advertisements.
I, ALBERT EDWARD RODGERS, of 64, Mark Lane, in the City of London,
Engineer, 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 improvements in means for displaying advertisements
by giving intermittent motion to frames, cylinders or the like of suitable design
and shape, containing the advertisements, by the use of electricity from primary
or secondary batteries or other source of electricity in such a manner that by
merely moving any object (such as a door) in a building an electric circuit will be
completed by a suitable arrangement of mechanism and cause the frame or
cylinder to automatically move in various ways and thereby display the
advertisements consecutively or otherwise.
To enable my invention to be fully understood I will describe the same with
reference to the accompanying drawing, in which :-
Figure 1 is an end view of apparatus, for displaying advertisements, constructed
according to my invention, part of the case of the said apparatus being removed to
shew the internal mechanism :
Figure 2 is a side elevation of the apparatus.
a is the frame or cylinder on which the advertisements are displayed, the said
frame being mounted on pivots b. On one of the pivots b is a ratchet wheel c
adapted to be actuated by a weighted pawl d pivoted to a bell-crank lever e, f
having its fulcrum at g. The short arin f of the bell-crank lever is pivotally
connected to the armature or core of a solenoid i. j is a battery or other source

page_text: of electricity conveying current to the solenoid i by means of the wires k, l,
and m is a switch interposed at any desirable point in the circuit, the said switch
being operated in any suitable way such as for instance by the opening and shutting
of a door.
n is a stop on the free end of the long arm of the lever e, f to prevent the
overbalancing of the weighted pawl d and o is a second stop on the said lever to
prevent the frame or cylinder a rotating more than a predetermined distance, the
said stop coming in contact with the ratchet wheel c when the frame has moved
through a certain distance.
The operation of the apparatus is as follows:-When the current is caused to
flow through the solenoid i owing to the operation of the switch m the armature or
core is drawn into the said solenoid thereby forcing the longer arm of the
bell-crank lever upwards so as to cause the pawl d to actuate the ratchet wheel c
and thus to rotate the frame or cylinder a until the stop o comes in contact with
the ratchet wheel c. When the switch is again operated to interrupt the circuit
the weight of the long arm of the lever and the pawl carried thereby causes the
movement of the lever so as to lift the core to its upper position and place the
pawl in engagement with another tooth of the ratchet wheel.
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. Improvements in displaying advertisements consisting in imparting inter-
mittent motion to a rotating frame or cylinder, upon which the advertisements are
displayed, by means of electrically actuated mechanism controlled by a switch or
contact device operated by the opening and shutting of a door or the like,
substantially as described.
2. The improved apparatus for displaying advertisements hereinbefore described
and illustrated in the accompanying drawing.
