My said Invention relates to apparatus for automatically supplying given quantities
of liquids from casks or other receptacles containing beer, wine, spirits, oil or other
liquids of value, the discharge of the required quantity being effected by inserting a
coin or coins of the requisite value into a shute or slit in connection with the
apparatus.

valve prevents any of the liquid displaced in the vessel from finding its way back to
the cistern. When the displacing body is again raised the reduced level of the
liquid in the chamber is restored by a fresh inflow from the cistern. The means and
apparatus for thus lowering and raising the displacing body are as follows:-

A suitably formed shute receives the coin or coins which slide into a pivotted and
counterbalanced coin receiver. When the proper coin, or proper number of coins, has
been placed in the shute the counterbalance weight is overcome and the coin receiver
turns on its pivot, dropping the coin or coins into a locked receptacle or till placed to
receive the money. The spindle constituting the pivot of the coin receiver carries a
stop, which as the receiver swings downward is moved away from in front of a tooth,
projection or notch on or in a disc, which latter is thus allowed to revolve, a suitable
arrangement of clockwork being provided to supply the motive power for revolving
the disc. By the time the disc has made one revolution, the pivoted coin receiver has

balance weight as soon as the coin or coins have been dropped into the till. The dise
is therefore stopped at the end of one revolution by the retaining stop on the pivot
spindle coming opposite to the tooth, notch or projection on or in the disc. A crank
on the axle of the disc is connected by a rod to a lever and spindle which acts by links
or otherwise on the aforesaid displacing body in the chamber on the cistern so as to
force it down and lift it up during each complete revolution of the disc and crank.
The connecting rod from the crank is connected to the lever in such a manner that it
can be adjusted, to move the lever through a greater or less are of a circle, so that the
immersion of the suspended displacing body or plunger can be regulated to a nicety
and an exact quantity of liquid delivered.
My improved apparatus could be fixed in connection with refreshment and railway
bars, hotels, restaurants, on board of vessels and in similar places of public resort and
not only enables customers to help themselves and so dispense with waiters and
attendants, but also acts as a check to prevent dishonesty. The apparatus could also
be employed in other situations for example in connection with oil tanks or receptacles
in work shops and factories, the apparatus being operated by means of tokens instead
of coins, the said tokens being stamped or numbered and served out to foremen or
other responsible persons.

I JOHN HOLROYD of the firm of John Holroyd and Company Limited of Tomlinson
Street, Hulme, Manchester, in the County of Lancaster, Engineers and Machinists
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 and accompanying drawings
--
My said Invention relates to apparatus for automatically supplying given quantities
of liquids from casks or others receptacles containing beer, wine, spirits, oil or other
liquids of value, the discharge of the required quantity being effected by inserting a

The cask or other receptacle is placed in communication with an intermediate cistern
or receptacle fitted with a ball cock so as to maintain a fixed level of liquid in the said
intermediate cistern.
A second smaller vessel is fixed to and communicates with the said cistern a similar
liquid level being maintained therein, and in the said vessel is suspended a cylinder,
or body, or plunger capable of being lowered or thrust down so as to displace a certain
fixed quantity of the liquid in the chamber and cause it to rise and overflow through
an aperture into the delivery tap or into a chamber connected therewith. A check

apparatus for thus lowering and raising the displacing body are as follows:-
A suitably formed shute receives the coin or coins which slide into a pivotted and
counterbalanced coin receiver. When the proper coin, or proper number of coins,
has been placed in the shute the counterbalance weight is overcome and the coin
receiver turns on its pivot, dropping the coin or coins into a locked receptacle or till
placed to receive the money. The spindle constituting the pivot of the coin receiver
carries a stop, which as the receiver swings downward is moved away from in front of
a tooth projection or notch on or in a disc, which latter is thus allowed to revolve, a
suitable arrangement of clockwork being provided to supply the motive power for
revolving the disc. By the time the disc has made one revolution, the pivotted coin
receiver has resumed its normal position relatively to the shute being brought back by
the counterbalance weight as soon as the coin or coins have been dropped into the till.
The disc is therefore stopped at the end of one revolution by the retaining stop on the
pivot spindle coming opposite to the tooth, notch or projection on or in the disc. A
crank on the axle of the disc is connected by a rod to a lever and spindle which acts
by links or otherwise on the aforesaid displacing body in the chamber on the cistern
so as to force it down and lift it up during each complete revolution of the disc and

page_text: crank. The connecting rod from the crank is connected to the lever in such a manner
that it can be adjusted to move the lever through a greater or less are of a circle, so
that the immersion of the suspended displacing body or plunger can be regulated to a
nicety and an exact quantity of liquid delivered.
In order that my said invention may be properly understood I will now proceed more
particularly to describe the same with reference to the annexed two sheets of drawings
which illustrate my improved apparatus.
Fig. 1 (sheet 1) is a front elevation of the apparatus, the containing case being
shown in section.
Fig. 2 is a plan of Fig. 1.
Fig. 3 (sheet 2) is a view at the money receiving end of the apparatus the lower
part of the case not appearing.
Fig. 4 is a sectional view of the cistern and vessel from which liquid is discharged
by displacement.
Figs. 5 and 6 are detail views of the apparatus.
The apparatus illustrated in the drawings is supposed to be enclosed in a box A
made of wood or other suitable material but it may be fixed or situated in
any other
suitable manner or situation. The cask or other receptacle containing the liquid to
be supplied is connected by a pipe to the inlet B leading to the cock C by which the
liquid in the cistern D is maintained at the proper level by means of the floating ball E
which opens the cock C when the liquid level has fallen and shuts it again when the
level has been sufliciently raised. A second smaller vessel F is attached to and placed
in communication with the intermediate cistern D by means of a hollow branch G
through which the liquid finds its way from the cistern D into the vessel F. As the
liquid in the cistern ) is maintained by the ball cock at a constant level, the same
level is also maintained in the vessel F. In the vessel F and suspended over or partly
immersed in the liquid is a body H seen most clearly in Fig. 4 (sheet 2) which is a
sectional view of the cistern D and vessel F. Just above the level of the liquid in the
vessel F is an overflow opening into the chamber I and delivery pipe J. The branch
containing this overflow conduit is marked K. It will be evident that if the body H
is pushed down in the vessel F, the liquid therein will be displaced and caused to rise
and overflow into the chamber I and thence into the delivery pipe J into a vessel held
to receive it. The head of pressure set up in the vessel F by the displacing action of
the body H is prevented from flowing back into the cistern D by a back pressure valve
in the branch G. As seen at Fig. 4 the said back pressure valve consists of a disc L
hung on a pin in a chamber in the branch G so that it is pushed by the back pressure
against a face in the branch, so as to shut off communication between the vessel F
and the cistern D. The movement of the displacing body H can be exactly regulated
by adjustable screws M, in the top and bottom of the vessel F. A certain fixed
quantity of liquid is thus caused to overflow and be delivered. When the displacing
body is again raised the reduced level of liquid in the vessel is restored to its normal
height by a fresh inflow from the cistern.
The raising and lowering of the displacing body and the consequent delivery of a
measured quantity of the liquid is effected by the introduction of coins in the following
manner. The mouth of a shinte N projects at an upward angle through the side of the
case or box A containing the apparatus. This shute is of such a size and of such pro-
portions as to exactly fit and carry the coins (for example pennies) which it is
intended the apparatus should receive, and to reject or cause to be forfeited coins
which differ from the requirements. The apparatus shown in the drawings is intended
to receive and to act upon receipt of two coins (for example two pennies). These
coins are slipped down the shute N one after another and enter a pivotted and
counterbalanced coin receiver O. This coin receiver is pivotted at P, the outer end of
the pivot pin being supported by a bracket attached to a plate X which lies against
the end of the cistern. A counterbalance weight R which is adjustably secured to a
tail projecting from the coin receiver keeps the coin receiver in line with the shute N
so that the coins slide down into the receiver. As soon as the receiver has obtained
its complement of coins (say twopence) the balance is destroyed and it turns upon

page_text: its pivot into the position indicated in dotted lines (Fig. 3) delivering the coins
into a locked drawer or till S beneath the receiver see Fig. 1. The counterbalance
weight R immediately returns the receiver into line with the shute N ready to
receive more coins. This swinging movement of the coin receiver is utilised to
actuate the body H in the vessel F by means of the following intermediate arrange-
ment of mechanism. As most clearly seen at Fig. 3 of the drawings a crank disc T
is fixed on the revolving pivot pin P and from the said crank disc a link U.
extends to a crank V fixed on a spindle W. Now referring to Fig. 1 of the
drawings it will be seen that this spindle W extends through the plate X and
through the side plates or cheeks Y Y of a frame containing an arrangement of
clockwork Z. Fig. 5 is a detail view of the cheek Y namely that one which is
furthest from the coin shute and receiver. Here is seen the termination of the
spindle W the said termination carrying a curved stop a. As seen in the enlarged
view Fig. 6 the spindle W is notched or cut down between the cheek Y¹ and the
curved stop a and opposite to a disc b carried on the end of a spindle c which is at
times actuated by the clockwork Z. The said clockwork is of an ordinary or
suitable construction to which I lay no claim and which I will not therefore describe
at length. The constant tendency of the clockwork is to rotate the spindle c and
disc b. The spindle W prevents this constant rotation of the disc as it lies in
the path of the tooth d which projects from the disc band rests in contact with the
spindle W. The nose of the curved stop a on the spindle W lies beneath a pin e¹
on the disc and prevents the disc from being turned back. When the coin
receiver swings round, the spindle W is turned in the direction of the arrow Fig. 6
bringing the reduced portion of the spindle opposite to the tooth d and allowing
the tooth to pass and the disc b to rotate. As seen in Fig. 5 the spindle c of the disc
also carries a crank e which is connected by a link to a lever g on a spindle h. As
the disc rotates the said lever g is depressed, turning the spindle and lowering the
displacing body H in the vessel F so as to displace and deliver the required quantity
of liquid. The spindle is connected to the body H by a lever i and link as clearly
seen at Fig. 4. The position of the displacing body when lowered, is clearly shown
in dotted lines. As soon as the coin receiver has dropped the money into the till the
counterbalance weight returns it immediately to its normal position, turning the
spindle W back to the position shown in Fig. 6 so as to arrest the revolution of
the disc when the tooth d comes round again. The disc is then held positively
between the stop a and the spindle W until released by the introduction of fresh
coins. The lever g (see Fig. 5) is slotted so as to render adjustable the point of
attachment of the link and thus provide for the most exact adjustment of the
body H. The coin receiver might be arranged to act on receipt of a greater or
less number of coins than two. The whole apparatus might be placed upon or
beneath a counter or a number of such apparatus might be arranged around a
refreshment or railway bar, or in connection with hotels, restaurants on board of
vessels and in other places of public resort-and not only enables customers to
help themselves and dispense with waiters and attendants but also prevents dis-
honesty. The apparatus might also be fixed in workshops and factories for example
in connection with the supply of oil from tanks or receptacles the apparatus being
operated by tokens instead of coins the said tokens being stamped numbered and
served out to foremen store-keepers and other responsible persons. I am aware of
Everitt's specification 10,23287 and I wish it to be understood that I do not claim
anything described & claimed therein.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed 1 declare that what
I claim is :-
(1) The general arrangement and combination of parts comprising the apparatus
for automatically supplying a measured quantity of liquid in exchange for a coin
or coins or for a token or tokens substantially as hereinbefore described and shown.
(2) In apparatus for automatically supplying a measured quantity of liquid in

page_text: exchange for coins or their equivalents the coin or token receiver O centred upon a
pivot and sustained in line with the shute by means of a counter-balance weight, and
so arranged as to be overbalanced by the weight of a coin or of coins and to swing
round so as to deposit the coin or coins in a receptacle and to be immediately returned
in line with the shute by the counterbalance weight, substantially as hereinbefore
described and shown.
(3) In apparatus of the indicated description the hereinbefore described pivotted
coin receiver O in combination with the means for releasing and arresting the disc b,
substantially as hereinbefore described and shown.
(4) In apparatus of the indicated description supplying a measured quantity of
liquid from a vessel by the use of a displacing body H, arranged adjusted and actuated
substantially as hereinbefore described and shown.

I JOHN HOLROYD of the firm of John Holroyd and Company Limited of Tomlinson
Street, Hulme, Manchester, in the County of Lancaster, Engineers and Machinists
do hereby declare the nature of this Invention and in what manner the same is to bo
performed to be particularly described and ascertained in and by the following
statement and accompanying drawings :-
My said Invention rolates to apparatus for automatically supplying given quantities
of liquids from casks or other receptacles containing beer, wine, spirits, oil or other
liquids of value, the discharge of the required quantity being effected by inserting a
coin or coins of the requisite value into a shute or slit in connection with the
apparatus.
The cask or other receptacle is placed in communication with an intermediato cistern
or receptacle fitted with a ball cock so as to maintain a fixed level of liquid in the said
intermediate cistern.
A second smaller vessel is fixed to and communicates with the said cistern a similar
liquid level being maintained therein, and in the said vessel is suspended a cylinder,
or body, or plunger capable of being lowered or thrust down so as to displace a certain
fixed quantity of the liquid in the chamber and cause it to rise and overflow through

valve prevents any of the liquid displaced in the vessel from finding its way back to
the cistern. When the displacing body is again raised the reduced level of the liquid
in the chamber is restored by a fresh inflow from the cistern. The means and
apparatus for thus lowering and raising the displacing body are as follows:-

A suitably formed shute receives the coin or coins which slide into a pivotted and
counterbalanced coin receiver. When the proper coin, or proper number of coins,
has been placed in the shute the counterbalance weight is overcome and the coin
receiver turns on its pivot, dropping the coin or coins into a locked receptacle or till

The apparatus illustrated in the drawings is supposed to be enclosed in a box A
made of wood or other suitable material but it may be fixed or situated in any other
suitable manner or situation. The cask or other receptacle containing the liquid to
be supplied connected by a pipe to the inlet B leading to the cock C by which the
liquid in the cistern D is maintained at the proper level by means of the floating ball E

through which the liquid finds its way from the cistern D into the vessel F. As the
liquid in the cistern ) is maintained by the ball cock at a constant level, the same
level is also maintained in the vessel F. In the vessel F and suspended over or partly

The raising and lowering of the displacing body and the consequent delivery of a

actuate the body H in the vessel F by means of the following intermediate arrange-
ment of mechanism. As most clearly seen at Fig. 3 of the drawings a crank disc T
is fixed on the revolving pivot pin P and from the said crank disc a link U
extends to a crank V fixed on a spindle W Now referring to Fig. 1 of the
drawings it will be seen that this spindle W extends through the plate X and
through the side plates or cheeks Y Y¹ of a frame containing an arrangement of
clockwork Z. Fig. 5 is a detail view of the cheek Y' namely that one which is
furthest from the coin shute and receiver. Here is seen the termination of the
spindle W the said termination carrying a curved stop a. As seen in the enlarged
view Fig. 6 the spindle W is notched or cut down between the check Y' and the
curved stop a and opposite to a disc carried on the end of a spindle c which is at
times actuated by the clockwork Z. The said clockwork is of an ordinary or
suitable construction to which I lay no claim and which I will not therefore describe
at length. The constant tendency of the clockwork is to rotate the spindle c and
disc . The spindle W prevents this constant rotation of the disc 'as it lies in
the path of a tooth d which projects from the disc and rests in contact with the
spindle W. The nose of the curved stop a on the spindle W lies beneath a pin el
on the disc band prevents the disc from being turned back. When the coin
receiver swings round, the spindle W is turned in the direction of the arrow Fig. 6
bringing the reduced portion of the spindle opposite to the tooth d and allowing
the tooth to pass and the disc to rotate." As seen in Fig. 5 the spindle c of the disc b
also carries a crank e which is connected by a link to a lever g on a spindle h. As
the disc rotates the said lever is depressed, turning the spindle h and lowering the
displacing body H.in the vessel F so as to displace and deliver the required quantity
of liquid. The spindle is connected to the body H by a lever i and link k as clearly
seen at Fig. 4. The position of the displacing body when lowered, is clearly shown
in dotted lines. As soon as the coin receiver las dropped the money into the till the
counterbalance weight returns it immediately to its normal position, turning the
spindle W back to the position shown in Fig. 6 so as to arrest the revolution of
the disc when the tooth d comes round again. The disc is then held positively
between the stop a and the spindle W until released by the introduction of fresh
coins. The lever 7 (see Fig. 5) is slotted so as to render adjustable the point of
attachment of the link and thus provide for the most exact adjustment of the
body H. The coin receiver might be arranged to act on receipt of a greater or
