GEORGE COWLEY BINGHAM of King's College Chambers London (Student) in the
county of Middlesex, do hereby declare the nature of this invention to
follows:-
The liquid is contained in a vessel preferably of a semi-cylindrical shape, the afore-
said vessel being caused to revolve about an axis by means of a weight or other agent,
in such a manner as to empty it of its contents. Connected to the aforesaid axis, upon
which the aforesaid vessel revolves and revolving with it is a toothed wheel or ratchet
into the teeth or stops of which, pawls or stops attached to a lever work in such a
manner as to prevent the toothed wheel or ratchet revolving, until one end of the
aforesaid lever is depressed. Upon the depression of the end of the lever before
mentioned, the aforesaid toothed wheel or ratchet, together with the aforesaid vessel
to which it is connected makes a part of a revolution, and again upon its being raised
the aforesaid pieces make another part revolution.
The lever is loaded in such a manner as to make it assume a certain position unless
depressed by means of a coin, coins, or counters placed in a bucket attached to the
end of it, the aforesaid bucket being made such as to discharge its contents in falling
by striking a pin, and so causing the lever to assume its original position.
It will thus be seen that by the insertion of a coin, coins or counters into the bucket,
the lever will be depressed and the toothed wheel or ratchet will make a part revolu
tion, thus allowing the vessel to make a part revolution, and so partly emptying
itself of its contents; again on the discharge of the coin, on fall of lever, the lever
will assume its original position thus allowing the toothed wheel or ratchet to make
another part revolution, and the vessel with it, causing the vessel to again partly
empty itself.
The whole of the aforesaid mechanism to be contained in a case or box, having such
openings in it as to allow the liquid to flow out, the coin or coins to be passed into the
bucket, and others necessary to indicate when the vessel is empty etc.

page_text: 1. GEORGE COWLEY BINGHAM Student of King's College London in the County of
Middlesex, do hereby declare the nature of this invention and in what manner the
same is to be performed, to be partilarly described and ascertained in and by the
following stateinent:
This invention relates to an apparatus for the delivery of a certain quantity of liquid
on the introduction of a suitable coin or coins.
To effect this I make use of a reservoir of such construction that upon its being
moved in a predetermined manner will discharge a definite quantity of liquid at each
such move, combined with a locking arrangement to prevent such movement until
released by the insertion of a suitable coin or coins into an aperture, apertures, or
receptacle for the purpose.
The manner preferably in which I construct the apparatus is made clear by the
following explanation of accompanying drawing. Fig. (1) shows the mechanism of
an apparatus in elevation of the nature of my invention of which Fig. (2) is the plan.
The whole of the said mechanism being contained in a box or case with suitable
openings for the discharge of liquid and the insertion of coins etc. The case not being
shown in the drawing.
.
In Figs. (1) and (2) the reservoir (A) is shown in this case constructed to revolve
about the axis of that part of the reservoir consisting of a tube (B) and forming the
opening for discharge, and having opening (C) for filling. It will thus be seen that
upon the reservoir being turned in the direction as indicated by the arrow, the
liquid will flow from the vessel through the opening (B). To effect this revolution
I make use in this case of a weight (D) which from its moment about (B) tends
to produce this motion. To prevont as hereinbefore stated a quantity of liquid
being discharged before the insertion of a coin or coins into an aperture or apertures
or receptacle for the same, I attach to the tube before mentioned an escapement wheel
against the tooth No. (2) of which projects tooth No. (1) of the lever (E).
The lever (E) being capable of oscillating about the fulcrum (F). It will thus be
seen that until the end of the lever (E) to which a receptacle (H) for the suitable
coin or coins is attached, is depressed the reservoir will remain stationary, and upon
that end of the lever being depressed will revolve to such an extent as is predetermined
by the position of the tooth No. (2) upon the said lever, and No. (1) upon escapement
wheel. But (E) is so constructed that upon a suitable coin being placed in the
receptacle (H) it causes that end of the said lever to be depressed, and the partial
revolution as before described to take place. Again from the construction of the
receptacle (H) for coin, attached to the lever (E) the coin is kept in the receptacle by.
a fixed surface (K) down which the coin slides, and it will therefore be seen that at
the end of the surface the coin will fall from the receptacle, and thus released from
the weight of the coin the lever will again recover its normal position by means of the
counterweight (G). By so doing, disengaging tooth No. (2) of lever from tooth

page_text: No. (1) of escapement wheel, therefore allowing reservoir to revolve until stopped by
the tooth No. (3) on escapement wheel and No. (1) a lever coming into contact, dis-
charging a fresh quantity of liquid. From the construction of the foregoing apparatus
it becomes obvious that by the insertion of a coin or coins into the receptacle (H) the
lever (E) will be made to rise and fall allowing the reservoir to revolve as herein-
before described. And if the teeth of escapement wheel are constructed so as to
be of equal distances apart the reservoir will deliver equal quantities of liquid at each
move, through the opening (B).
It is obvious from the nature of the invention that the reservoir could be modified
in shape and be made to act in various ways by the insertion of a coin.
For example
the reservoir may be turned by hand suitable means being provided outside the case.
The escapement, wheel might be used in combination with gearing or dispensed with
entirely and other means provided for locking purposes.
The reservoir might be made to revolve about a point not its centre. It might also
be prismatic, conical, spherical or any convenient form other than illustrated by the
accompanying drawing.
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.
1. The combination of mechanism as herewith described and illustrated, with a
reservoir such as to deliver by its revolution a fixed quantity of liquor by the insertion
of a suitable coin or coins into an aperture or receptacle for the purpose.
2. The modification of the apparatus as herewith before described.
3. The combination of parts forming the apparatus for the delivery of a given
quantity of liquid in exchange for an equivalent coin, as herein described, and
illustrated by accompanying drawing.
