Improvements in Electric Lighting by Means of Coin Freed
Apparatus.
We,
DIXON HENRY DAVIES of No. 4 South Parade, Leeds in the County of
York, Solicitor, and JOIN MESNEY TOURTEL of Adelaide Works, Uxbridge Road
in the County of Middlesex, Engineer do hereby declare the nature of this invention
to be as follows:-
we
In the Specifications of our Patents Nos. 820687 52018 and 578989
described apparatus so arranged that on inserting a coin and moving a push an
electric light is produced and maintained for a time determined by clockwork forming
part of the apparatus. Such apparatus was designed more especially for use in
railway carriages when the journeys were of long duration so that the clockwork
determined the time for which the light was given for the payment made. When
however the journeys are of short duration the clockwork can be dispensed with
and our present invention relates to improved means and apparatus, whereby the
light is produced by inserting a coin and moving a push, which light is capable of
being extinguished either at the option of the person using such light by means of
a second push in the apparatus, or the whole of the lights contained in the circuit
can be extinguished by a temporary interruption of the main circuit, so that the
guard or other person at the end of each journey or at the end of a certain period
of time can by the movement of a switch on the main circuit, interrupting the current
for a moment, extinguish all the lights in the train and on the completion again of
the circuit place all the apparatus in a condition to be operated by the insertion
of a fresh coin and the movement of the push.
For this purpose we arrange each apparatus in a branch circuit so that the
light governed by such apparatus is capable of being extinguished by the person
using it without interfering with the lights operated by the other apparatus in the
other branch circuits.
Each apparatus consists of a casing provided with a spring push and containing
a pivotted coin pocket as described in our former Specification No. 578980. At
the back of this coin pocket is attached au armature provided with a contact piece,
which armature and contact piece are on the insertion of a coin and the movement
of the main push brought respectively against an electro magnet and against a
contact spring arranged behind such electro magnet and on being brought into
contact complete the branch circuit causing the lamp to give light and are retained
in that position until an interruption of the current takes place. Such interruption
of the current can be caused in each apparatus by means of a second push, operated
by the person using the light, forcing the contact spring away from its contact
piece, allowing the pivotted coin pocket with its armature and contact piece to
return to its normal position in obedience to its spring, without interrupting the
main circuit and the other apparatus. In like manner an interruption caused in
the main circuit will release every contact piece from its contact spring allowing all
the coin pockets with their armatures and contact pieces to return to their normal
positions in obedience to their spring actions.
On the interruption to the main current being removed each apparatus is placed
in such condition that it can be again operated by the insertion of a coin and the
movement of its push.
Although I have described this system of operating with coin freed apparatus of
a special construction the means can be equally applied to coin freed apparatus
of different constructions.

Improvements in Electric Lighting by Means of Coin Freed
Apparatus.
We, DIXON HENRY DAVIES, Solicitor, of Chesterfield, in the County of
Derby, and JOHN MESNEY TOURTEL, Engineer, of 12 Talbot Road, London,
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 :--
In the 'Specifications of our Patents Nos. 8206 of 1887, 5201 of 1888 and 15789
of 1889 we described apparatus so arranged that, on inserting a coin and moving, a
push, an electric light is produced and maintained for a time determined byrclock-
work forming part of the apparatus. Such apparatus was designed more especially
for use in railway carriages, when the journeys were' of long duration; so that the
clockwork determined the time for which the light was given for the payment
made. When however the journeys are of short duration the clockwork cant be
dispensed with and our present invention relates to improved means and apparatus,
whereby the light is produced by inserting a coin and moving a push, which light
is capable of being extinguished either at the option of the person using such light
by means of a second pushi in the apparatus; or the whole of the lights contained
in the circuit can be extinguished by a temporary interruption of the main circuit,
so that the guard or other person at the end of each journey or at the end of a
certain period of time can by the movement of a switch on the main circuit, inter-
rupting the current for a moment, extinguish all the lights in the train; and,
the completion again of the circuit, can place all the apparatus in a
condition to be operated by the insertion of a fresh coin and 'the movement
of a push.
on
For this purpose, we arrange each apparatus in a branch circuit, so that the
light governed by it is capable of being extinguished by the person'using it without
interfering with the lights operated by the other apparatus in the other branch
circuits: The 'several apparatus are constructed and arranged as will now be
described with reference to the accompanying drawings.
Figs. 2 and 5 are sectional elevations and Figs: 3 and 4 sectional plans
of the apparatus, Figs. 1, 2 and 3 shewing it at rest and Figs. 4 and 5 in
action.
Fig. 6 is a diagram' shewing the electrical connections for several sets of the
apparatus.
The same letters are used throughout, as far as possible, to designate similar parts
in the various figures.
A is a casing having a door F hinged at I l' and provided with a lock m. In
a socket D projecting from the door F is fitted a plunger P which is kept in its
forward position, as in Fig. 1, by a spring pressing against a barg projecting
'from the inner end of the said plunger, which bar is kept in a vertical position by
a slotted' guide h (Fig. 5)..
At H H within' the casing A is pivotted a pocket N which is kept in a forward
position by a spring G. To a projection R behind the pocket N is attached an
armature a having a contact piece r.
In the centre of the pocket N is a hole through which the plunger P passes
freely, when pressed in, without operating the pocket. But when a coin of the
required value is inserted into the slot S it' drops within the pocket Nandrests
upon a ledge T projecting from the side of the casing beneath the pocket (Fig. 2)
and, upon the plunger P being pressed in, it strikes the said coin, as shewn in
Fig. 5, and carries back the pocket Nr and brings the armature a against the
poles of an electromagnet M, and completes an electric circuit producing a
fight, as shewn in Fig. 6, by bringing the contact piece against a contact

page_text: spring Q(Fig. 4). An electric current now passes through the coils of the electro
magnet M which are in the clectric circuit, exciting the electro magnet and causing
it to retain the armature a against the poles 77 and the contact piece against the
contact spring Q. The plunger P can now be released and is brought to its normal
position by the spring f, and the coin being now beyond the ledge T will drop
within the casing A.
In a socket d projecting from the door F is a spring push p which upon being
pressed in moves a slide J (Figs. 1 and 4) and forces the contact spring Qaway
from the contact piece r. The electric circuit being thus broken the electro
magnet M is rendered inert and the pocket N is brought by the spring G to its
original position as in Figure 1.
Should the electric circuit be broken outside the casing A, then upon introducing
a coin and operating the mechanism as above described a light will not be produced
nor will the electro magnet M be excited, so that, upon releasing the plunger P, the
pocket N (still containing the coin) will be forced forwards by the spring G, and its
momentum will carry it beyond the ledge T and allow the coin to drop down a
shoot I, and through a hole in the bottom of the casing A, to a catch k from which
the operator may regain it. Thus the coin is returned to the operator unless the
apparatus produces a light.
If a coin too small be inserted, it cannot rest upon the ledge T but drops
past it, as shewn in Fig. 2, and falls upon the catch through the shoot l.
In Fig. 2 are shewn the clectrical connections within the case A: U is a safety
fusc, and the branch leads x and y (in oue of which is placed the incandescent
electric lamp) are connected to the main conductors to and from the battery or
other source of electricity.
In Fig. 6 B is the battery or other source of electricity; and t are electric
mains on branch circuits of which are placed several apparatus of which A' A³
and A' are shewn in action the circuits being completed and their lamps L L and L*
being alight. A² is out of action. K is a switch on the main circuit by which the
main circuit can be temporarily opened; as in that case the current ceases to flow
through the branch circuits, the electro magnets M' M³ and M' are rendered inert,
and the switches and with their armatures a¹ a³ and at and their contact
pieces and are released from the poles 7' 7' and ' and the contact
springs QQ and Q, and return to their normal positions as shewn in A². Upon
S
the switch K again closing the main circuit all the apparatus are ready to be
operated afresh.
It is obvious that, according to the arrangement shewn in Fig. 6, other forms
of coin freed apparatus besides that herein described, might be connected by
branch leads to main conductors so as to render the operation of cach independent
of the others.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
Connecting several sets of coin freed apparatus for electric light by branch leads
to main conductors provided with a switch by which all the sets can be put into or
out of operation, each set being provided with a separate switch, substantially as
and for the purpose herein set forth.
