PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Supplying Gas or other Fluid on
Prepayment, Partly Applicable to other similar Apparatus
Operated by a Coin.
We JOHN HAWKYARD, Foreman and JOSEPH BRADDOCK, Gas Engineer, both
of Globe Meter Works Oldham in the County of Lancaster do hereby declare
the nature of this invention to be as follows:-
This invention relates to improvements upon the automatic apparatus for which
we made application for Letters Patent No. 12584 dated August 12th 1890, the
objects being to simplify and cheapen the apparatus.
In the first place we drive the "first motion wheel by means of a worm
instead of a long pinion; the end wise motion of the short shaft or spindle being so
slight that the teeth of the "first-motion wheel will always remain in contact
with the worm.
The endwise motion may be given to the shaft or spindle either by a spring
acting against it or against the "first motion" wheel, either directly or by means
of a lever, and a weight may be substituted for the spring.
Secondly the supply valve is fixed directly upon the end of the short shaft or
spindle, the seating and passages being cast or formed in the frame of the
apparatus.
The "first-motion" wheel drives the pointer which is fixed on the end of the
shaft or spindle and the ratchet wheel drives the dial plate which is fixed to its
boss.
Thirdly we dispense with the ram or pusher and we make the coin receiver in
the shape of a cylindrical box with a longitudinal slot (the size of the coin) above
and another corresponding slot beneath. Inside this box is a slotted cylindrical
"coin-receiver" into which the coin is dropped. The receiver is then partially
turned round by means of a thumb-piece or button outside and in revolving the
coin acts against the tooth of the ratchet wheel so as to revolve the circular cam.
As soon as the coin receiver has made nearly half a revolution the coin falls
out through the lower slot into a receptacle beneath.
On the boss of the ratchet wheel is a stop wheel provided with a catch which is
also raised by the coin in revolving coming against a tail piece. The catch is held
down either by a spring or a weight.
The teeth of the ratchet wheel enter the cylindrical box through a slot made in
the side of the same and the revolving coin-receiver is made with a corresponding
notch so that it does not act upon the teeth of the ratchet wheel unless it contains
a coin.
It will be obvious that this improved revolving coin-receiver is also equally
applicable to other similar automatic apparatus worked by a coin.
Dated this 16th day of September 1890.

Improvements in Apparatus for Supplying Gas or other Fluid on
Prepayment, Partly Applicable to other similar Apparatus
Operated by a Coin.
We JOHN HAWKYARD, Foreman and JOSEPH BRADDOCK, Gas Engineer both
of Globe Meter Works Oldham in the County of Lancaster 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 upon the automatic apparatus for which
we made application for Letters Patent No. 12584 dated August 12th 1890 the
object of the present invention being to simplify and cheapen the apparatus.
The nature of our said invention and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference
to the annexed sheet of drawings and the following explanation thereof.
Fig. 1 is a front elevation of the upper part of a wet gas meter showing our
improved apparatus as applied thereto.
Fig. 2 is a longitudinal section through the apparatus, and Fig. 3 a detached
transverse section.
So far as is practicable the main parts of the apparatus are marked with the
same letters of reference as are used in the Specification and drawings of the
Letters Patent No. 1258400 above referred to.
In the first place
we drive the first motion wheel d by means of a worm c instead
of a long pinion. The endwise motion of the short shaft or spindle e being so
slight that the teeth of the first motion wheel & will always remain in contact with
the worm c.
The endwise motion may be given to the short shaft or spindle e either by the
spring acting against it directly as shown, or by a spring acting against the first
motion wheel d, or by means of a lever, or a weight may be substituted for the
spring.
The shaft or spindle e passes through a stuffing box e¹.
Secondly the supply valve 7 is fixed, attached to or formed directly upon the end
of the short shaft or spindle e, the seating and passages 12 being cast or formed
in the frame of the apparatus as shown at Fig. 2.
The first motion wheel d drives the pointer p which is fixed on the end of the
shaft or spindle e and the ratchet wheel y actuates the dial plater which is fixed to
its boss.
Thirdly we dispense with the ram or pusher and we make the coin receiver in
the shape of a cylindrical box f' with a longitudinal slot (the size of the coin)
above and another corresponding slot beneath. Inside the box is a slotted coin
receiver w which is capable of being turned about half a revolution and back again
its motion being controlled by means of two stops w³ and w².
When a coin has been dropped through the upper slot into the coin receiver w
the latter is turned partially round by means of a thumb piece won the outside,
and in revolving the coin acts against a tooth of the ratchet wheel g (which teeth
are in this case made deeper than before) so as to revolve the circular cam h.
As soon as the coin-receiver w has made nearly half a revolution the coin falls
out through the lower slot into the receptacle У beneath.
On the side or boss of the ratchet wheel g is a stop wheel 9 provided with a
catch on a lever at which is also raised by the coin, in revolving, coming against
the tail piece of the said catch lever, (see also Fig. 3), which is held down by
a spring or a weight, so as to prevent the wheel g from revolving unless released
by the coin.
The teeth of the ratchet wheel y enter the cylindrical box f¹ through a slot made

page_text: in the side of the same and the revolving coin receiver w is made with a corre-
sponding notch (see Figs. 2 and 3) so that it does not act upon the teeth of the
ratchet wheel a unless it contains a coin.
g
It will be obvious that this improved revolving coin-receiver w may if preferred
be made to revolve completely and is also equally applicable to other similar
automatic apparatus worked by a coin.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :
-
The various improvements upon our automatic gas-supplying apparatus substan-
tially as hereinbefore described and illustrated by the drawings annexed and
especially we claim the construction of revolving, or partially revolving coin
receiver substantially as hereinbefore described, whether the same be applied to
our improved automatic gas supplying apparatus or to other similar automatic
apparatus worked by a coin.
