I HUBERT FEILDEN JACKSON of 11 Queen Victoria Street in the City of London
Go hereby declare the nature of this Invention to be as follows:-
My Invention has for its object to provide a simple and efficient arrangement in
connection with telephones whereby it is indicated at the exchange or other placo
when payment or the authorized equivalent is made at the calling station for the use
of the telephones.
According to my Invention I combine with the line wire of the telephone a
telephonic transmitter which transmits sounds to the exchange or other place by the,
passage of coins or by the action of an authorative key or token put into a shoot
and receptacle or its equivalent at the calling station as payment for the use of the
telephones.
Whilst not limiting myself to precise details the following is an arrangement
according to my Invention.
At the calling station is the ordinary set of instruments comprising a transmitter
receiver and bell (or the like) in connection by the line with the exchange or distant
station.
At the calling station there is also a receptacle for the coins with a shoot or passage
through which the coins pass on their way to the receptacle. In about or forming
part of this shoot is a diaphragm or transmitter in circuit with the line wire or with
a battery and the primary of an induction coil the secondary of which is in the line
wire. The said transmitter or diaphragm is so placed that the coins pass in contact
with it or with projections on it as the said coins fall through the shoot to the

page_text: receptacle and so a sound is transmitted to the exchange or other distant station
indicating that the fee for the use of the telephones has been paid. The shoot or the
equivalent for the coins tokens or the like may be arranged in any suitable way to
admit to the diaphragm only coins of the proper kind.
In cases where it is desired that the insertion of an authoratative key shall be
intimated a contrivance such as a lock is provided so that when the key is inserted
and turned the transmitter will be affected to give an indication at the distant station
analogously to the action herein before described.

1 HUBERT FIELDEN JACKSON of 11 Queen Victoria Street in the City of London
Gentleman 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:-
My Invention has for its object to provide a simple and efficient arrangement in
connection with telephones whereby it is indicated at the exchange or other place
when payment or the authorised equivalent is made at the calling station for the use
of the telephones.
According to my invention I combine with the line wire of the telephone a
telephone transmitter which transmits sounds to the Exchange or other place by the
passage of coins or by the action of an authoritative key or token put into a shoot
and receptacle or its equivalent at the calling station as payment for the use of the
Telephones.
Whilst not limiting myself to precise details the following is an arrangement
according to my Invention.
At the calling station is the ordinary set of instruments comprising a transmitter
receiver and bell (or the like) in connection by the line with the exchange or distant
station.
At the calling station there is also a receptacle for the coins with a shoot or passage
through which the coins pass on their way to the receptacle. In about or forming
part of this shoot is a diaphragm or transmitter in circuit with the line wire or with
a battery and the primary of an induction coil, the secondary of which is in the line
wire. The said transmitter or diaphragm is so placed that the coins pass in contact
with it or with projections on it as the said coins fall through the shoot to the
receptacle and so a sound is transmitted to the exchange, or other distant station,
indicating that the fee for the use of the telephone has been paid. The shoot or the
equivalent for the coins tokens or the like may be arranged in any suitable way to
admit to the diaphragms only a coin or coins of the proper kind.
In cases where it is desired that the insertion of an authoritative key shall be
intimated, a contrivance such as a lock is provided so that when the key is inserted
and turned the transmitter will be affected to give an indication at the distant station
analogously to the action hereinbefore described.
And in order that my said Invention may be fully understood 1 shall now proceed
more particularly to describe the same and for that purpose shall refer to the several

page_text: -
figures on the annexed sheet of drawings the same letters of reference indicating
corresponding parts in all the figures.
Figure 1 is a diagram illustrating an application of my invention A represents a
devico according to my invention placed at the desired station and B represents an
ordinary or any suitable set of telephonic instruments comprising a telephone a
transmitter and a bell or signalling apparatus.
C indicates the line wire running to the switch room and being connected to the
ordinary spring jack and annunciator.
1 is a shoot (arranged for any predetermined size of coin) the base of which shoot
forms the diaphragm of a transmitter 2 which is in circuit with a battery 3 and the
primary wire of an induction coil 4 whose secondary wire is in the line circuit running
from Cto B cc are corrugations or projections on the diaphragm arranged at regular
or irregular intervals.
The action will be as follows, Each time a coin is inserted it will run over the base
of the shoot and will alter the electrical condition of the circuit of which the
transmitter 2 is a part. The line circuit C will also change in its electrical state
relatively with the circuit of which the transmitter 2 is a part and a receiver in the
switch room will be so influenced as to emit a rumbling sound in which a sharp
cracking sound will be heard whenever the coin passes over one of the corrugations or
projections c.
The case in which the device A is fitted preferably is composed of or lined with
some dense non vibrating material for instanco the tran-mitter may be attached with
the intervention of india rubber.
Figure 2 shows another arrangement according to my Invention 1 is a shoot
having an aperture at its head A' into which coins of the predetermined kind can be
inserted. This shoot 1 is open at 1 and opposite the opening a balanced shoot D
pivoted at and regulated by an adjustable weight D2 is placed into which the coin
falls the weight of the coin overtips the balance D till it assumes the position shown
by the dotted lines.
In this position the coin can pass from the shoot D) into another shoot A' the base
of the shoot A is the diaphragin of a transmitter B. The coin after passing from
the shoot D runs over this diaphragm and thence into the box. C is an induction
coil the primary circuit e¹ of which is completed through a suitable battery and the
transmitter B the secondary circuit c is included in the ordinary line wire to the
operating room.
The balanced shoot D carries a point d which when the said shoot is overtipped
allows two springs e and to come into contact. These springs when in contact
complete the primary circuit of the induction coil through a battery and the
transmitter.
The balanced shoot D cannot fall to its normal position until the coin has passed
over the diaphragm into the box. A lover M pivoted at m has a point n at one end
engaging the shoot D and a tray O at the other end so that the coin after passing
from the diaphragm B runs onto the tray O depresses the lever M and raises the
point n and so allows the shoot D to assume its norinal position. The battery is thus
kept in circuit during the desired period.
The balanced shoot D has on its upper inner surface a point b which is adjustable
and can be arranged to prevent the further passage of any coin. It will be seen that
if arranged for pence this size of coin will stop in the balance D will tip it over (the
weight being regulated to allow of this) and will pass into A2. But if a smaller
coin be inserted it will pass through D without tipping it and can be allowed to drop
into the box or pass down a slot P communicating with a tray p on the exterior of
the box and thus be returned to the inserter.
As it is desirable that the ordinary speaking instruments and the box should not
be in circuit at the same time a spring switch can be arranged as in Figure 3.
9 is a spring in contact with the lower side f¹ of spring f which lower side is
insulated from the upper side when the shoot D.is.in its normal position.

is connected to the exchange wire.
fis connected through the two transmitters and the primary of the induction coil
to one pole of the battery.
o is connected through the secondary of the induction coil to earth.
e is connected to the other pole of the battery.
When the shoot D is in its normal condition it will be seen that connection is made
between and but broken between f" and e and between L and o.
Thus when the shoot D is in its normal position the box is cut out of circuit and
the speaking instruments put in.
When the shoot D is overtipped the speaking instruments are cut out and the box
is put in.
It is unnecessary to show the apparatus in the operating room as it need be in no
way different to that in use in every switch room.
To provide a checking mechanism suitable for another class of coin say for sixpenny
pieces I arrange a shoot communicating with A Figure 4 similarly to the shoots A A'
and D in Figure 2.
The base of the shoot A' instead of being the diaphragm of a transmitter has a
small and very flexible spring 1 attached to it.
This spring 1 passed through the base rests on the end of the lever 2 pivoted at 3
and having at its other end a point 5 which rests at a stop 6 on the surface of a
wheel this wheel carries the escapement of a clock movement shown in the
Figure. Cis the diaphragm of a transmitter 1) (say for example of the Edison Blake
type) connected to line through an induction coil as already described. The coin as
it passes through A¹ presses on the spring 1 raises the point 5 and releases the
wheel B and sets the escapement in motion the lever 2 then assumes the normal
position stops the clock by catching the stop 6 arranged as desired. The air vibration
made by the movement of the escapement actuate the diaphragm of the transmitter
and the ticking of the clock can then be heard by the oxchange operator. A balance
similar to that already described is put on the transmitter battery as previously
described.
To enable entitled persons to use the box without charge and to indicate to the
operator their bonâ fides they are provided with a key.
Figure 5 shows a lock, which would be placed on the front of the box having a
bolt which when raised by the turning of the key, raises the point 5 as in Figure 4
and sets the clock going. This clock mechanism is the same as that released by the
coin and shewn in Figure 4.
To provide checking arrangements for a key representing a different value, I use
a different shaped lock and gear it in exactly the same way to another clock which
clock gives a different sort of tick to that previously used i.c. with a longer or shorter
click. The operator can then distinguish the use of the key entitling to different
uses of the telephone.
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.
First. In combination with telephones a transmitter so arranged that sounds are
transmitted to a distant station or exchange on the insertion of a coin or authoritative
key or the equivalent substantially as hereinbefore described.
Second. In an arrangement for the purpose described and claimed a diaphragm
provided with corrugations or projections as described with regard to Figure 1.
Third. In an arrangement for the purpose described and claimed the tipping shoot D
operating as hereinbefore described.

page_text: Fourth. The arrangement as and for the purpose hereinbefore described and illus
trated by Figure 2.
Fifth. The arrangement as and for the purpose hereinbefore described and illus-
trated by Figure 3.
Sixth. In an arrangement for the purpose hereinbefore described a clock mechanism
released and retained substantially as described with regard to Figure 5 whether the
clock be released by a coin or by a key or whether more than one clock be used to
indicate different values substantially as hereinbefore described.
