IMPROVEMENTS IN THE MEANS OF EFFECTING COMMUNICATION IN TELEPHONIO SYSTEMS
Year: 1884

page_text: PROVISIONAL SPECIFICATION.
We LOUIS JOHN CROSSLEY of Dean Clough Mills Halifax, Carpet Manufacturer,
JOHN FREDERIC HARRISON of Bradford, Wool Comber and WALTER EMMOTT of
Halifax Electrician, all in the County of York do hereby declare the nature of our
invention for IMPROVEMENTS IN THE MEANS OF EFFECTING COMMUNICATION IN
TELEPHONIO SYSTEMS to be as follows:-
This invention relates to certain improvements in the means whereby a com-
munication can be effected in ordinary telephonic systems.
Hitherto communication has been made between the subscribers and the
Exchange at the will of the subscriber by external means or apparatus but in
our improvement, communication can only be effected by first depositing into
a suitable receptacle a coin or voucher or an authoritative representation of such
coin,
In order to carry out our invention we arrange either that the coin or its
equivalent shall make contact or close a circuit or that the coin or its equivalent
sball actuate such mechanical or electrical device in order to make contact or close
& circuit.
Now whilst it is impossible in our improvement for the subscriber to make any
connection until the consideration has been deposited yet the operator at the
Exchange can call up the Subscriber and also stop the communication at will.
Dated this 13th day of September 1884.

page_text: COMPLETE SPECIFICATION,
We, LOUIS JOHN CROSSLEY of Dean Clough Mills, Halifax, Carpet Manufacturer,
JOHN FREDERIC HARRISON of Bradford, Wool Comber, and WALTER EMMOTT of
Halifax, Electrician, all in the County of York, do hereby declare the nature of our
invention for IMPROVEMENTS IN THE MEANS OF EFFECTING COMMUNICATION IN
TELEPHONIO SYSTEMS, and in what manner the saine is to be performed, to be
particularly described and ascertained in and by the following statement :—
This invention relates to certain improvements in the means whereby a com-
munication can be effected in ordinary telephonic systems.
Hitherto communication has been made between the subscribers and the
Exchange at the will of the subscriber by external means or apparatus, but in
our improvement communication can only be effected by first depositing into
a suitable receptacle a coin or voucher, or an authorative representation of such
coin
In order to carry out our invention, we arrange either that, the coin. or its
oquivalent shall make contact or close a circuit, or that the coin or its equivalent
shall actuate such mechanical or electrical device in order to make contact or close
a circuit.
Now whilst it is impossible in our improvement for the subscriber to make any
connection until the consideration has been deposited, yet the operator at the
Exchange can call up the subscriber and also stop the communication at will.
One means by which our invention may be carried out: We make use of a lever
or its equivalent capable of being moved by the weight of the, coin voucher or
token. This movement alone is sufficient to enable the subscriber to obtain the
attention of the Exchange, by causing the lover to close a local circuit, but we find
the system is rendered more complete when the lever or its equivalent is caused to,
actuate the armature of an Electro magnet or better still the tongue of a polarized
relay.
By winding the coil or coils of tho relay with wire of a suitable size, we find that
it can be arranged not to respond to the rapidly alternating currents produced by
a. Magneto Generator, but any suitable battery will deflect the needle to either side,
as may be required. This enables us to carry out the following operation: After
the subscriber has deposited the required consideration in the suitable receptacle,
the relay tongue is brought over to the side required. This makes the connection
by which the subscriber is enabled to communicate with the operator in the
telephonic Exchange,, but the timo during which this communication shall last,
is entirely under the control of the Exchange operator, who can interrupt the
communication at any moment by simply sending a current of electricity from any
suitable battery. This will release the needle from the position in which it has
been placed by the subscriber depositing his "consideration," and until a further
consideration is deposited, he is unable to obtain further communication except by
the operator's consent,

page_text: If desired it is clear that the simple movement of the relay can be utilised to
close a local circuit and thus call up the subscriber without further trouble on the
part of the subscriber.
A mechanical counter or check applied to the lever or its equivalent will enable
the number of times the apparatus is used to be seen at a glance.
By the foregoing arrangements it will be seen that the operator has the full
control as to the time during which a communication shall be maintained, but it
may be desirable to take this entirely out of the operator's hands, and this may be
accomplished by causing the coin token or its equivalent to start a train of clock
work either at the subscriber's end, or in the Exchange which shall keep the circuit
through during the time specified..
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim, is
The effecting of a connection between the subscriber and the telephone Exchange,
or telephonic operator by means of a voucher coin, or its equivalent, substantially
in the manner herein set forth.
The means whereby telephone Exchange or operator can at will make or break
communication with the subscriber, substantially in the manner herein set forth.
