PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Effecting by Insertion of a Coin the
Production of Electric Light for a Certain Time.
We, DIXON HENRY DAVIES, of No. + South Parade, Leeds, in the County of
York, Solicitor, and JOHN MESNY TOURTEL, of Adelaide Works, Uxbridge Road, in
the County of Middlesex, Engineer, do hereby declare the nature of this invention
to be as follows:-
In our Specifications No. 8206 of 1887 and No. 5201 of 1888 we have described
apparatus so arranged that on inserting a coin and moving a push, an electric light
is produced and is maintained for a time determined by clockwork forming part of
the apparatus.
Our present invention relates to apparatus of this kind, and has for its object to
simplify the apparatus and render it more compact, convenient and inexpensive,
particularly by dispensing with the separate clockwork required in each apparatus
and controlling the time for a number of separate apparatus by a master clock which
governs them all.
In each separate apparatus, according to our present invention, there is, as before,
a pocket formed between two swinging plates, but it is open at the bottom. The
coin is dropped between those plates and rests when it is of the proper size, by its
edge on a stationary lateral fillet, or when it is not of the proper size it drops past the
fillet to an outlet. There is also a spring push which, when pressed inwards, passes
clear through a hole of the pocket, but, if there is a coin in the pocket, the push
forces it back and brings an armature which the pocket carries up to the poles of an
electro magnet. The movement of the pocket at the same time turns a ratchet wheel
one tooth, and thus makes a contact, so that a current of electricity passes through
the coils of the electro magnet and also through the filament of a glow lamp,
producing light.
The pocket having been moved past the fillet, as soon as the push is released the
coin drops from the pocket into a receptacle below, but so long as the electro magnet
remains excited, attracting the armature, the pocket is held in its back position.
Should there be a failure in the supply of electricity so that no light is produced,
there is no attraction of the armature, and the pocket is pushed forwards by a spring
carrying with it the coin which on being brought by the momentum in front of the
fillet falls to the outlet and is restored.
For determining the duration of the light we adopt the following arrangement of
conductors for a battery or other source of electricity common to a number of separate
apparatus. From the one pole we lead a conductor with branches to the separate
|lamps with a contact switch interposed in each branch. From the other pole we lead
a second conductor with a branch directly to each lamp, and we lead also a third
conductor with a branch to each electro magnet coil, from each of which a wire
leads to the first mentioned branch for each lamp between the lamp and the contact
switch.
The third conductor from the battery has a contact switch which is momentarily
broken by a clock at certain regular intervals, say every five minutes, thus rendering
all the electro magnets momentarily inert. A second armature to the electro magnet
in each apparatus is thus caused to make a to and fro stroke thereby turning the
ratchet wheel one tooth. When the ratchet wheel has thus been turned a certain
number of teeth, each at a regular interval of time, an insulating piece on the axis of
the ratchet wheel is brought to bear on the lamp contact switch opening the circuit
and extinguishing the lamp. The master clock, instead of making at intervals a break
of contact as above described, may make at these intervals a momentary contact,

page_text: causing the ratchet wheels to be turned tooth by tooth, and in this case the coils of
the electro magnets besides being connected to the clock lead are also connected to the
lamp lead through a switch contact which is made only when the push is moved.

Improvements in Apparatus for Effecting by Insertion of a Coin the
Production of Electric Light for a Certain Time.
We, DIXON HENRY DAVIES of No. 4 South Parade Leeds, in the County of York,
Solicitor and JOHN MESNY TOURTEL of Adelaide Works Uxbridge Road in the County
of Middlesex, 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 :-
In our Specifications No. 8206 of 1887 and No. 5201 of 1888 we have described
apparatus so arranged that on inserting a coin and moving a push, an electric light is
produced and is maintained for a time determined by clockwork forming part of the
apparatus. Our present invention relates to apparatus of this kind, and has for its
object to simplify the apparatus and render it more compact, convenient and
inexpensive, particularly by dispensing with the seperate clockwork required in each
apparatus and controlling the time for a number of separate apparatus by a master
clock which governs them all.
Figs. 1 and 2 of the accompanying drawings are vertical sections on planes at right
angles to each other of the apparatus embodying our present improvements, and
Fig. 3 is a diagram showing the electrical connections to several sets of the apparatus.
In each separate apparatus, according to our present invention, there is, as before, a
pocket D formed between two swinging plates but it is open at the bottom. The coin
is dropped between those plates and rests when it is of the proper size by its edge on
a stationary lateral fillet G, or when it is not of the proper size it drops past the
fillet G to an outlet L and lodges on a coin catch M. There is also a spring push P
which, when pressed inwards, passes clear through a hole of the pocket D, but, if
there is a coin in the pocket the push forces it back and brings an armature h,
which the pocket carries, up to the poles t of an electro magnet T¹. The move-
ment of the pocket D at the same time by means of a pin d bearing against an
incline on a pawl lever B turns a ratchet wheel Cone tooth, and thus makes a
contact so that a current of electricity passes through the coils of the electro magnet
and also through the filament of a glow lamp producing light. The pocket D having
been moved past the fillet G, as soon as the push is released, the coin drops from the
pocket into a receptacle A below, but so long as the electro magnet remains excited,
attracting the armature the pocket is held in its back position. Should there be
a failure in the supply of electricity so that no light is produced, there is no
attraction of the armature and the pocket D is pushed forwards by a spring J
carrying with it the coin which on being brought by the momentum in front of the
fillet G falls to the outlet L and catch M, being thus restored. T is a second
electromagnet having in front of its poles an armature on the lever B, so that when T
is excited it attracts its armature and thus moves the lever B causing the ratchet
wheel C to turn one tooth. On the axis of C is a wheel Chaving a piece or
several pieces c of insulating material on its circumference, and against the edge
of this wheel bears a spring c', the wheel and spring constituting a switch S
(Fig. 3) which maintains contact with c¹ during all the revolution of the wheel
except when the insulating material c presents itself to the spring c¹. From the back
of the pocket D projects a pin d' against a contact spring d² constituting a switch S¹
(Fig. 3) which closes a circuit as long as the pocket D is held in its back position. For
determining the duration of the light we adopt the arrangement of conductors, shewn

page_text: in Fig. 3. K is a battery or other source of electricity common to a number of
separate apparatus N' N' &c. From the oue pole of K we lead a conductor k¹ with
branches to the separate magnets T and lamps L with the contact switch S interposed
in each branch. From the other pole we lead a second conductor k with a branch
through the switch S¹ to each lamp and we lead also a third conductor ³ with a branch
through the coil of each electro magnet T2 from each of which a wire leads to the
first mentioned branch for each lamp between the lamp L and the contact switch S.
The third conductor from the battery has a contact switch S3 which is moved to make
momentary contacts by a clock at certain regular intervals, say every five minutes,
thus momentarily exciting all the electro magnets T2. Thus the armature lever B in
each apparatus is caused to make a to and fro stroke thereby turning the ratchet
wheel one tooth. When the ratchet wheel has thus been turned a certain number
of teeth, each at a regular interval of time, the insulating piece c is brought to bear
on the spring cl which forms the switch S thus opening the lamp circuit and
extinguishing the lamp.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed we declare that what we claim in
respect of apparatus for effecting by insertion of a coin the production of electric
light for a certain time, is
The combination of two or more incandescent electric lamps and their respective
coin freed apparatus with a battery or other source of electricity common to them all,
and with a single clockwork arranged to make momentary electric contact at certain
intervals with one of three conductors arranged and connected substantially as
described with reference to Fig. 3.
