Means or Appliances for Delivering Prepaid Liquids in
Prearranged Quantities.
WILLIAM SAMUEL OLIVER Albert House St. Pauls Road Canonbury, N.
Engineer do hereby declare the nature of this invention to be as follows:-
My invention consists of an apparatus into which when a prearranged coin is
dropped, a prearranged quantity of liquid shall be delivered outside the machine,
automatically or by pushing or moving a slide or other device from without.
To carry out my invention I construct my apparatus preferably upon the following
plan.
A reservoir contains the liquid which in some cases is kept warm by a hot water
jacket, sand bath or other convenient method, the temperature being preferably kept
constant by a gas jet regulated automatically by a thermometer in any of the well
known plans or otherwise. The aforesaid reservoir opens into a tube which terminates
in the spout to deliver the liquid and which bears two valves the cubic content of the tube
aforesaid between the valves equalling the prearranged quantity to be delivered. These
valves are so arranged that one is always open and the other shut at the same moment.
This I preferably effect by a rack and cogwheels, the cogwheels being attached to the
valves aforesaid and the rack actuating them. The rack moving these valves is con-
nected with a bellows communicating by a tube with another bellows normally kept
open by a spring or weight which latter bellows is attached to and actuated by a rod
or other device projecting from the machine.
In the tube connecting the bellows the one with the other is a hole normally open
so that the bellows cannot be effectually actuated, as the air escapes, but the hole
aforesaid can be closed by a valve when a prearranged coin is dropped into a shoot
connected with it. The action of the machine is as follows. A coin having been
dropped into the aforesaid shoot closes the aforesaid valve by overballancing a lever or
other device. The rod or slide pushed in or pulled out actuates the first bellows and
forces the air from it into the second one which it inflates, producing the mechanical
movement necessary to turn or move the valves and allow to escape outside the
P11

page_text: apparatus the fluid which was previously rosting between the two valves. There is an
arrangement consisting preferably of a pin on one of the bellows to dislodge the coin
and allow the valve to open and the parts to resume their first position. This I effect
preferably by a spring or weight and I place proferably a spiral spring in one or both
of the bellows. Instead of the aforesaid method I sometimes use the coin as a key to
connect the push pin with the working parts of the machine, so that they cannot be
actuated until a coin has dropped into a slot or other contrivance. Or I may use the
weight of sand, shot, or the like or instead of air I may use steam, air expanded by
heat, gas, or any liquid to inflate the bellows aforesaid or move a fan or other device.
Or I may use an electro magnet.
When I use sand or the like I construct my machine preferably as follows. The
sand is contained in a reservoir furnished with a valve and so arranged that on the
valve being opened by the weight of a coin falling on a lever or other device a pre-
arranged quantity of sand falls upon and over ballances a catch locking the push pin or
other device actuating the valves in the tube leading from the vessel containing the
liquid to be delivered, to the spout. Or I may use the weight of the sand to open the
valves themselves in this case preferably allowing the sand to fall into and turn a
chambered wheel connected with them.
In the case where I use an electromagnet, the coin moving one metallic contact
against another or itself acting as a metallic contact between two parts of a divided
circuit completes an electric circuit in which the electro magnet aforesaid is placed
and thus actuates it moving an armature which may by the mechanical movement
thus produced either lift the locking catch aforesaid, make a connection between two
working parts of the machine or turn or move one or more of the valves. Or I may
use two or more of the aforesaid methods in combination.

I WILLIAM SAMUEL OLIVER, of Albert House St. Pauls Road Canonbury, N.
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 :-
My invention relates to an apparatus into which, when a pre arranged coin is
dropped, a pre arranged quantity of liquid shall be delivered outside the machine
after pushing or moving a slide or other device from without.
To carry my invention into practice I construct my apparatus preferably upon the
following plan.
A reservoir contains the liquid, which in some cases is kept warm by a hot water jacket,
kept constant by a gas jet, regulated automatically by a thermometer in any of the
well known plans or otherwise. The aforesaid reservoir opens into a tube which
terminates in the spout to deliver the liquid and which bears two valves, the cubic
content of the tube aforesaid between the valves equalling the prearranged quantity
to be delivered. These valves are so arranged that one is always open and the other
shut at the same moment. This I preferably effect by a rack and cogwheels, the cog
wheels being attached to the valves aforesaid and the rack actuating them.
The rack moving these valves is connected with a bellows communicating by a
tube with another bellows normally kept open by a spring or weight which latter
bellows is attached to and actuated by a rod or other device projecting from the machine.
In the tube connecting the bellows one with the other is a hole normally open so
that the bellows cannot be effectually actuated, as the air escapes, but the hole
aforesaid can be closed by a valve when a pre-arranged coin is dropped into a shoot.
The invention in its simplest form is shown on the annexed drawing Figure 1.
A is the liquid container enclosed in a tank B the water in which is heated by the
gas jet C for warming the contents of the liquid container A when desired the gas or
other heating arrangement being turned down by a Thermometer rod D when the
heat arrives at a given temperature said rod D then acting on the valve E of the gus
supply pipe F or its equivalent.
G is a spout at the bottom of the vessel A to lead a given quantity of liquid to the
outer nozzle H. In this spout a couple of cock plugs I. J are fitted, said plugs being
set in opposite directions to be opened and closed simultaneously by the double
rack K gearing into pinions on the cocks spindles when the push pin or stud L is acted
upon in either direction, that is to say, when the stud L is pushed in the rack rod K
travels inwards to shut the plug I of the upper tap to cut off communication with the
container A the other tap J being simultaneously opened to allow the defined quantity
of drink that was temporarily held between the two taps 1. J to flow to the outlet
nozzle H.
M. N are two bellows connecting the rack rod K with the push rod L, said bellows
having a communication by the hollow stem P provided with a flap valve Q, see
Figure 2 for the transfer of the air from the bellows M. to the bellows N.
R is an intermediate pipe between the two bellows M, N provided with a tap S
this having two passages T, U, (see Figure 3) in it, one marked T being for the
supply of air to the bellows M and the other marked U for the escape of the air
from the bellows N but the depression of the lever X by the weight of the coin
causes the plug S to close both openings T U so that the push of the rod L forces the

page_text: air out of the bellows M into the bellows N through the connecting pipe.P. the valve
in said pipe closing automatically against back pressure. When the springs V, W,
uct, one of which springs, V, expands the bellows M, and the spring W contracts the
bellows N. This action happens when the rod x returns after being depressed by
the reception of a coin on the receiver Y, the weight of the coin being sufficient,
coupled with the shock the lever Z receives from the coin dropping down the shoot a.
The coin receiver in its downward travel first bears against or upon a spur L' of a
locking bolt L to release said bolt from the rod L, the coin receiver on the lever Z
also rests upon an angled bar M¹ the lower end of which is attached to the bellows M
to temporarilly retain the coin lever Z until the rod L is pushed in; the angled bar M¹
is then gradually pushed away from supporting the lever Z, which release allows the
coin and lever end to rub against an inclined wedge piece b which causes the receiver Y
to cant sideways and discharge the coin, which coin falls into the drawer or till C₁
lever Z then, under the action of the counterbalance d, resumes its normal position
and by the rod X causes the valve S to turn and open the two passages to the air
inlet e and air outlet f.
the
When I use an electro-magnet with my liquid supply apparatus as at Figure 4,1
provide the lever Z with a couple of pole plates j, k, which as the lever Z is depressed-
by the weight of the coin falling on the pocket at the bottom of the shoot a-dip into
the mercury in the bason to close the electric circuit, the magnet m then attracting
the armature n to release the nose or catch from the lip q on the push rod K, said
push rod K being then free to be operated as before described for closing the tap I
and opening theitapJ.
The drawings only show examples of appliances to be employed with my apparatus
for ensuring an automatic supply of a pre-arranged quantity of prepaid liquids I
therefore do not limit myself to the precise method or combination of appliances
specified.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I declare that what I claim is :-
1. The apparatus substantially as shown on the annexed drawings from which a a
defined quantity of liquid (hot or cold) can be allowed to flow to outlet nozzle on a
push stud being operated after the insertion of a coin and the withdrawal of the bolt
as set forth.
2. In an apparatus for drawing off a defined quantity of liquid after the insertion
of a coin as above set forth, the two bellows M, N, and their connections P, R, S, a
acting substantially in the manner described and arranged as shown in the drawings.
3. An apparatus in which by the weight of a coin an electric circuit can be closed
and a hold fast or locking catch p be withdrawn from the push rod K substantially as
shown at Figure 4 when such an apparatus is in connection with a system for delivering
prepaid liquids in pre-arranged quantities as set forth.
4. As part of an apparatus from which a pre-arranged quantity of liquid (after the
placing of a coin) can be supplied the means substantially set forth and shown for
keeping the liquid at a given temperature automatically.
5. The delivery of a given quantity of liquid by the opening of one valve and
closing of another substantially as described when in an apparatus of the kind shown
by the annexed drawings.
Lastly, I claim :-The use of a jacketted reservoir for liquids which can be delivered
in defined quantities after the insertion of a coin.
