Automatic Machines for the Supply of Liquids on Draught by
Electrical and other Means.
BENJAMIN WILLIAM WARWICK 134 Highbury Hill London N. Electrician do
hereby declare the nature of this invention to be as follows:-
The object of this invention is to supply from automatic machines liquids on draught,
for commercial purposes or for refreshment. The liquids to be delivered may be
served in vessels, or run from a pipe and be caught in any suitable vessel provided in
the machine or otherwise. The liquids are to be delivered in definite quantities
measured by the machine, or in multiples of these quantities when larger sums of
money are placed in the machine. The liquids delivered are simple, or compound, in
various proportions to suit the taste of, and under the control of the purchaser; or in
a predetermined manner, as in mixing ale and beer. The liquids may be hot or cold,
as boiling water for tea, or iced drinks; with or without the addition of other
ingredients, such as milk in coffee sherbet in water or sugar in gin. Chemical
mixtures are also delivered, such as effervescing drink and seidleits powders in water ;
also soluble substances as jellies, essences and soups as food.
The stock is kept in large vessels of such form as to allow of refilling readily.
The liquid passes into a secondary vessel, preferably, and from this the service pipe
starts and has a press release controlled by the purchaser.
An important part of this invention is the provision for cleansing the drinking
vessel after use by purchasers. This I accomplish in several ways. By immersion in
water and withdrawal to dry or by allowing jets of water to play on it, by means of a
pump worked when the door is opened and discharging when it shuts; or cleaning by
contact with cloths or pads having a circular or rectilinear motion, but in every case
the vessel is cleaned and ready for the customer.
The means by which I prefer to actuate the parts is electrical. Thus I employ a
press or electrical switch which becomes effective after the coin or coins have been
suitably placed. Excited magnets move armatures attached to levers which open the
taps, and these are in combination with pneumatic valves to determine the duration
of flow by releasing the levers and cutting off supply. And these time regulating

page_text: valves are again compensated for error by reason of the varying pressure of liquid
in the main tank, by means of a float acting mechanically or electrically, this last
being placed in the large or in the smaller reservoir, so that whether the tank is
full or nearly empty, the purchaser will receive the guaranteed quantity.
The door which opens to allow access to the drinking vessel and taps has fastenings,
released by mechanical or electrical means.
The means employed to make the liquids hot is by flame or hot air passing along
tubes which the liquids surrounds. I employ any convenient sourse of heat, as gas,
oil lamps or other means the heat being shut off when the machine is not in action.
For producing cold I employ ice or refrigerating mixtures surrounding the liquids.
I regulate the proportions of the mixtures by controlling the valves of two or
more vessels and deliver through independent or a common duct.
With those things which require brewing like coffee, 1 allow the hot liquid to pass
through a sieve containing the substance, or immerse the container in the vessel of
hot water.
The electric batteries are placed in the base of the machine.
I now proceed by means of drawings to explain in detail the mechanism by which
I bring about the results indicated in the foregoing statements.
Fig. 1 is a front elevation and fig. 2 a side elevation of an automatic machine for
delivering a liquid, say ginger-beer, by mechanical means.
Fig. 3 is a plan of the parts above cy in fig. 1, and fig. 4 a plan of the parts
belowy in fig. 2. The parts in figs. 1, 2, 3 and 4 are lettered homologously.
"
The handle Pull" is on the end of a bar c e, shown in figs. 2 and 3, which moves
in guides, not indicated in the drawings, and is drawn back to its normal position by
the spiral spring S. On this bar is a carrier for the coin p; when the coin is placed
as shown, the bar cc, on being pulled carries with it the bar F, F, F. This bar
by means of a rod working through a slot in it turns on the tap A, best seen in figs. 1
and 3. The tap B being also open on account of the ballcock 6 being down in the
small vessel vv. The liquid now flows from the large vessel V through the pipe t into
the small vessel until supply is cut off by the ballcock rising. Having pulled
the bar c c out it is necessary to hold it so for a few seconds to allow the liquid to
flow. When the pull is released, the coin drops away on the right side; the
bar F, F, F, although pulled back by the spring St does not immediately follow the
bar c c because the pin K attached to F, F, F, is locked behind the pivoted bolt n, n;
but when the pin "K', attached to the bar c e passes the cain on the bolt n, n, the
bar F, F, F is then released and returns to its normal position. The object of this
last arrangement is to allow the coin to get free. When the bar F, F, F, is out in its
most forward position it raises the vertical bolt a a, which raises the latch hand
allows the door D to start open. The purchaser now has access to the drinking vessel,
which he finds inverted as shown. By pressing the button marked "Press" he gets
the liquid from the vessel v, v, through the tap E. This tap E is open normally but
shut when the bar c c is pulled out. It will be seen that there are four taps, of
which B and E are normally open. When A is open E is shut in the forward move-
ment ; in the backward movement, B being closed by the ballcock, A is closed
before E is opened. The last tap, the "Press," being controlled by the purchaser
alone. The money slot is at M. The drinking vessel is shown inverted in figs.
and 2 with the ring water jets Z Z, Z Z immediately above and below it. The
weighted piston W of the pump shown is drawn up by the chain H H when the door
is opened by the handle by the purchaser. Water is supplied from a tank in the
base of the machine. Having taken the liquid the purchaser replaces the drinking
vessel, which has a chain or other fastening, and shuts up the door, which is hinged
at u, u.
The piston of the pump now descends and forces the water along the
piper, r, and through the jets and swills the drinking vessel, which drains dry ready
for the next customer.
Fig. 5 is a side elevation and fig. 6 a front elevation of another method of cleaning
the drinking vessel by immersion in water. PPP is a grooved plate fixed at right
angles to the door D D and moves with it. in fig. 6 L L is a lever pivoted at K with

page_text: a stand S for the drinking vessel at one end of it. At point p on this lever the
upright rod R is pivoted, at its top end it carries a roller which runs in the grooves of
the plate P, P, P. When the door is opened this roller travels along the concentric
groove c c, and does not depress the lever L L, but when the door is closed the roller
travels along the straight groove O and causes the lever L L to descend and immerse
the stand S and with it the drinking vessel in the water tank below and withdraw
it again, which allows it to drain ready for the next customer.
Fig. 7 is a front elevation of an electrical combination for delivering liquids,
fig. 8 is a plan. L L is a money slot, p is a coin shown resting on a fixed carrier K
between two springs S S, which however the coin does not touch. A side eleva-
tion of this is given at the right hand side of fig. 7. When E P is pressed from
the outside of the case it makes electrical contact with Z, and also presses the
coin forward a short distance into contact with the two springs S S. An electrical
circuit is now established from the battery x through the coils of the electro
magnet M M to the contact z, the press E P is connected to the spring S by a wire,
the circuit d is completed through the coin to the other spring back to the battery.
When this happens the armature a. a. moves down and by means of the rod g g
presses the rubber disc valve ut fig. 8, down flat on the bottom of the vessel q. i., and
holds it down keeping open the tap A, as the armature is fixed to this. Liquid now
flows from vessel V to vessel vv along the pipe r. r.
When this smaller vessel v v is
full the ballcock brises and turns off the tap B; the valve holding down sufficiently
long to allow this to happen. When the armature a a is moved by the magnet M M,
it raises a latch which holds the door, and allows it to start open as in figs. 1 and 2,
or I employ a separate electro-magnet in this same circuit with the one drawn in the
figures to effect this. This means for starting the door is not shown in fig. 7.
door being started the purchaser opens it and gains access to the drinking vessel d d,
and by means of the "Press" gets the liquid from the vessel vv. On shutting the
door the drinking vessel is cleaned by methods already described, and is ready for
the next customer. The rod g g and the valve are drawn back to their normal
position by a spiral spring c fig. 8. There is a small passage p. s. fig. 8, from the
centre of the valve to the edge of the vessel to regulate the time of the action of the
valve. The ballcock 6 may instead of regulating tap B, regulate the passage p s to
effect the same object.
The
Fig. 9 is an elevation and fig. 10 a plan of a multiple carrier for coins to act
electrically. In the elevation, M M is the slot plate, p p p three coins resting on the
fixed carrier KKK. SS SS are flat springs which however the coins do not touch.
F F F are upright strips moved forward by the "press." They carry the coins
forward a short distance into contact with the springs S S S S, which are all then in
electrical series, and the circuit is established through them and the coils of the
magnet as in figs. 7 and 8. The coins are carried beyond the springs and projected
into the money box by additional strips not shown, carried by the armature of the
magnet.
Fig. 11 is an elevation and fig. 12 a plan of a multiple coin carrier to act
mechanically as in figs. 1 and 2. P,P,P, are three coins resting on fixed guides L LL.
The "Pull" rod cc has a cross frame with three upright bars c¹ c¹ c¹ behind the
coins. When this frame moves it carries the coins with it, the central coin carries
with it the bar FF F, which actuates the tap as in figs. 1 and 2. As the coins move
forward the two outside ones come against the pivoted clicks K K and press them
round in passing. Unless this happens the projecting parts t t of the frame F, F, F,
block against these clicks; so that if the central coin is alone placed, on pulling the
bar cc, the coin moves the bar F F F a short distance, but not enough to actuate
the taps, the projecting pieces t t come in contact with the tails of the clicks K K
and there block. If either one or two coins are placed in the side positions, on
pulling the bar cc, the bar F F F does not move, and the two coins are fulled
forward past the clicks and are forfeited; as also is the central one when placed
alono. It-will be seen therefore that to actuate the machine all the coins must be
placed, when the liquid will be delivered as guaranteed.

Fig. 13 shows my arrangement of reservoirs and tap for selling compound liquids.
B is a vessel holding say Brandy, and W holds water. V is a small vessel of known
capacity, and V₁ a vessel of double this capacity. The mechanism employed in
connection with this is either that shown in figs. 1 and 2, or in figs. 7 and 8. If the
purchaser requires some Brandy, he places say a sixpenny piece in the slot marked
Brandy alone." On either pulling the bar or making contact by pressing, the
tap 6 fig. 13 will be opened and the vessel V filled, the ballcock 6 cutting off supply.
By means of the "Press release the purchaser obtains the liquid as previously
described. If however water as well is required, the coin is placed in a different
slot, marked "with one third" or "with one half" water, this actuates a different
tap W, which allows both liquids to flow into the vessel V¹. The ballcock W₁ cutting
off supply. The purchaser now obtains the mixture in the same way as before. If
it is required hot, it may be made so by means shown in fig. 15.
22
Fig. 14 shows another arrangement of reservoirs and taps for selling compound
liquids. A holds say ale, B holds beer. I have three money slots in connection with
these, marked 1, 2, and 3. If a coin is placed in 1, it actuates by means of
mechanism previously described tap 1, this delivers say half-a-pint of beer, the
ballcock P cutting off supply; the purchaser may now obtain this. If the coin is
placed in slot 2, tap 2 is actuated and ale and beer flow into the vessels v¹ and v. The
ballcock P¹ being adjusted to cut off at a lower level, the half pint of the mixed liquid
is obtained as before If the coin is placed in 3, the tap 3 is actuated, and half-a-pint
of ale alone is obtained. If a coin is placed in 1 and in 3 as well, then a pint of liquid
will be obtained half-and-half. Two small valves are shown at t t to prevent the
liquid from flowing from one vessel to the other; or I employ a double "Press" also
to accomplish this.
Fig. 15 shows how the purchaser may have the liquid hot at will. When the
secondary vessel vv is full and the ballcock at its highest position as shown, the arm a
comes into the path described by the press button B, when this is so and the button
pressed, the gas tap is turned on and the ring jets ignited by means of the small
constant jet j. When the vessel is empty the ballcock and the arm a move to the
dotted position, and pressing B does not then ignite the gas. This press button is
inside the case like the drinking vessel, and access is gained by the door opening. This
is a method of heating the liquid at the option of the purchaser. I describe a little
furthur on a means of heating not under the control of the purchaser, I accomplish it
by electrical means with a magnet in combination with a time regulating valve to
keep the gas or source of heat burning sufficiently long to heat the liquid.
Fig. 16 is a sectional elevation of so much of the machine as will serve to show
a method of delivering various solubles, as sherbet, citrate of magnesia &c. The
door D gets open by means already described, disclosing the drinking vessel and one
or more handles H to deliver the various ingredients. The stock is kept in the
vertical case ST. On pulling the handle H the discharging piece d, which is
attached to the rod c, sends down the shoot h, h, a quantity of the powder or sugar as
wanted, it may rest on the ledge t, or fall into the vessel when a little shutter is raised,
not show in the figure. When the bar c is drawn out the vertical bar K K falls into
the notch Z, and the spring at a cannot replace the bar c until the door is closed,
drawing forward the bar B against the spring A and sending up the bar KK; the
handle H then goes to its normal position. Only one dose can therefore be obtained
each time the machine is worked. When more than one ingredient is offered to
choose from, if one handle is pulled, cross rods fall into notches in the other bars,
and prevent them being moved till the door is again closed, which again raises the
bars by means shown in fig. 16. When coffee or tea is sold a small quantity of
condensed milk is encased in a thin envelope of sugar to preserve it. The purchaser
may obtain milk if he wants it. Also additional sugar if required, I also deliver
these things already dissolved in the brewing vessel described in figs. 17 and 18.
I now give a description of the additional means employed for brewing in
combination with the mechanism already shown. Fig. 17 is an elevation and fig. 18
a plan.

page_text: The handle "Pull," the rod cc, the coin p, and the second bar F, F, F, are the
same as described in figs. 1 and 2. When the bar F, F, F, is drawn forward, the lugs
on it at move the handle of the tap B, and allow liquid to flow from the large
vessel V into the heating vessel H. When this last vessel is full, a ballcock rises
and cuts off supply by the tap at K. At the same time that the tap B is turned on,
the gas tap G is also turned on by a pin moving in a slot x in the bar F, F, F,
fig. 17. The small constant burner n ignites the ring jets under the heating vessel H.
It may be necessary for the purchaser to hold the "Pull" handle out sufficiently long
to boil the water, say one minute, with this arrangement, or I make the gas keep on
for this period automatically, by a clock train, or by electrical means, employing
magnets in combination with valves to turn off the gas when the water boils, a float
on water making the necessary electrical contact. The vessel H is formed with tubes
for the hot gas to pass through to heat the water quickly. When it boils a second
ballcock E makes an electrical contact and closes a circuit from the battery. By
through the "Bell," fig. 18, through the coils of the electro-magnet M M and the
vessel H. When the surface of the liquid is quiescent the contact is not made by
the ballcock E, but only when ebulition happens and the ballcock is tossed up, I
employ a mercury expansion contact to effect this, also a steam pressure valve on the
surface of vessel to make the contact, these however are not indicated in the drawings.
The armature n n above the magnet M M is fixed on the tap L which is turned on
when the circuit is completed. This tap is kept open by the stem O from the
armature pressing the valve R to the bottom of the vessel vv and holding then for a
time. When the liquid boils the Bell rings and the tap L opens and flow takes place
along the pipe i, i, i, into the movable container Z Z in the brewing vessel Y, Y.
The substance to be brewed gets into the container by being discharged by the piece d
down the shoot hh. This discharging piece d fig. 18 at the end of the arm a a, is
fixed to the bar F, F, F, so that the discharge of the substance along the shoot h, h,
happens at the same time that the gas is turned on and the tap B is opened. The
substance to be brewed does not fall straight into the container, but is stopped at the
bottom of the shoot by the shutter e, e. The container is hinged at f, and has and
arm standing in the path described by the pin p' which is fixed in the bar F F F.
So that when the bar F, F, F, is moved, the container is made to rotate on its hinge
through an angle of not less than 100°, and discharge the residue from the last
brewing. In the return path the edge of the container meets the passing click
on the hinge of the shutter at the bottom of the shoot, h, h, and opens it, and the
substance runs into the container and there awaits the hot liquid which comes
along the pipe i ii as already described. It is necessary for the purchaser to wait
a short time for the brewing. He then presents the drinking vessel, presses P
and the freshly brewed beverage flows from the vessel Y, Y. Milk, sugar or
other ingredients being supplied as in fig. 16.
In these statements I have set out the nature, scope, and substance of my invention
and have indicated the means by which I prefer to carry it out, but do not bind
myself to employ all the parts exactly as shown in these preliminary drawings.
Dated this 3rd day of January 1888.

page_text: Automatic Machines for the Supply of Liquids on Draught by
Electrical and other Means.
I, BENJAMIN WILLIAM WARWICK, of 134 Highbury Hill, London, N., Electrician
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:-
The object of my invention is to supply from automatic machines liquids on draught.
The liquids delivered may be served in a vessel or run from a pipe and in predeter-
mined quantity, simple or compound in various proportions, hot or cold, with or
without the addition of other ingredients. Effervescing liquids and other chemical
mixtures and other soluble substances can be delivered. I also provide means for
cleansing the drinking vessel.
To explain more clearly how my invention is carried out 1 refer to the drawings
which were furnished with the Provisional Specification, omitting Figs. 13, 17 and 18
and I also supply additional drawings.
Fig. 1. is a front elevation and
Fig. 2 is a side elevation of an automatic machine operated by mechanical means.
Fig. 3 is a plan of the parts above x, y.
Fig. 4 is a plan of the parts below x, y.
In these four figures similar letters represent the same parts.
The handle "PULL" is on the end of a bar c, c, which is drawn back to its normal
position by spring S. On this bar is a carrier for the coin P. When the coin is
placed. as shown the bar c carries with it the bar F which by means of the rod con-
nected to it turns on the tap A as shown in Figs. 1 and 3. The tap B is also open
because the ball-cock b is down in the vessel v. The liquid stored in the reservoir V
therefore now flows through the pipe into the vessel v. When the "PULL" is
released the coin drops away on the right side. The bar F although pulled back by
the spring S¹ does not immediately follow bar e because the pin K attached to F is
locked behind the pivoted bolt n, but when the pin K¹ attached to bar c passes the cam
shown on the bolt n the bar F is then released. During the time the bar F is thus
retained the coin is free to drop into the receptacle. When the bar F is in its most
forward position it raises the bolt a which raises the latch and allows the door D to
start open. There is now access to the drinking vessel which is inverted as shown
72

page_text: at R. When the button "PRESS" is pushed the liquid flows from the vessel v
through the tap E which is normally open but shut when c is pulled out by a rod
working on c. The liquid then either runs out or is liberated by a tap in the control
of the purchaser. M is the coin slit and shoot. The lower part of the machine is
occupied by a reservoir of clean water. When the door D is opened the piston W of
the pump shown is drawn up by chain H. When the door is shut the piston W
descends and forces the water through piper to the jet rings z, z. The drinking
vessel R is thus cleansed both outside and inside. The door D is hinged at u.
Fig. 5 is a side elevation and
Fig. 6 is a front elevation of a method of cleaning the drinking vessel by immersion.
P is a grooved plate fixed at right angles to door D and moving with it. L is a
lever pivoted at K with a stand S for drinking vessel at one end of it. At point p on
this lever the upright rod R is pivoted which at its top end carries a roller running in
the groove of plate P. When the door is opened the roller travels along the groove c
but on closing the door the roller travels along the groove o which causes the lever L
to descend and immerse the drinking vessel and withdraws it again.
Fig. 7 is a front elevation and
Fig. 8 is a plan of an electrical arrangement for actuating the apparatus.
Lis money slot. P is a coin shown resting on a fixed carrier K between two
springs S S which however the coin does not touch. The small figure at the right
hand of Fig. 7 is a side elevation of this part. When E P is pressed from outside the
case it makes contact with Z and also presses the coin P forward into contact with
the two springs S S. An electric circuit is now established from the battery
through the coils of the electro-magnet M to the contact Z. The press E P is con-
nected to one spring S by a wire and the current is completed through the coin P to
the other spring S back to the battery a. The armature a then moves down and by
means of a rod g presses the rubber disc valve ut flat on the bottom of the vessel gi
and holds it down keeping open the tap A as the armature a is fixed to it. The
valve ut holds down sufficiently long to allow the specified quantity of liquid to run
from the reservoir into the vessel v. so that ball cock may shut off tap B. The rod
and valve ut are drawn back to their normal position by spring c.
passage ps from the centre of the valve ut to the edge of the vessel q i regulates the
time of action of valve.
A small
Fig. 19 shows on a larger scale a contrivance in elevation whereby the tap B is
dispensed with and the ball-cock b acts upon the valve ut to secure the cut off.
The rod g as in Fig. 8 is attached to armature and when contact is made presses the
valve ut down to the position shown by dotted lines. When the tap B' is open there
is free communication from the vessel qi through the channel E to the underside of
the valve ut. When the valve ut is first pressed down the vessel vis empty and the
ball-cock b in the position shown in the drawing, and the tap B' closed. When the
ball-cock b rises to about the level of the tap B₁ opens, the valve ut is freed by
the passage of water or other contents of qi through channel E, and the spring c
shown in Fig. 8 draws back the rod and armature a and so shuts the supply
tap A.
Fig. 20 shows in elevation a contrivance for opening the door D when the electrical
method of actuating the apparatus is employed.
9.
The armature a pivoted to the tap A has attached to it the bar The dotted lines
show the position of the armature a and bar g' when contact is not made. A bent
lever H working in a slot d" in rod g' is pivoted at d¹ and ends in a latch & which
normally secures the door D. When contact is made the armature a, bar g¹ and
lever H are drawn into the position shown by the continuous lines of the figure
and the door D is released.
Fig. 21 shows another method of releasing the door D.
M is the yoke of the magnet M shown in Figs. 7, & 8. M" is an additional
magnet placed in the circuit. When contact is made the armature a¹¹ is drawn up
carrying with it the lever H which is pivoted to some part of the framing at d¹.
The latch or claw d is thus raised and the door D released.

page_text: Fig. 22 shows a front elevation and
Fig. 22 a side elevation of a contrivance for pushing the coin into the coin
receptacle when the electric method of actuating the apparatus is employed.
An additional slip of metal g carried by armature a is formed at its further
end into a fork g pressing on the coin P. The other letters are the same as in
Figs. 7 and This arrangement will also serve for more than one coin if
additional forks g₁ll be provided and can be used with the contrivance shown in
Figs. 9 and 10.
.but
While contact is broken the coin P rests a little way in front of fork g,."
when contact is made the movement of armature a pivoted on tap A causes a
forward movement of rod g¹ and fork gll which pushes the coin P into the
receptacle P¹.
Fig. 9 is an elevation and
Fig. 10 is a plan of a multiple carrier for coins to act electrically.
M is the slot plate. p, p, p are three coins resting on fixed carriers K, K, K.
S, S, S, S, are springs which the coins do not touch. F, F, F, are upright strips
moved forward by the "PRESS" carrying the coins forward a short distance into
contact with S, and establishing the current through them and the coils of the magnet
as shown in Figs. 7 and 8.
Fig. 11 is an elevation and
Fig. 12 is a plan of a multiple coin carrier acting mechanically.
P, P, P, are three coins resting on fixed guides L, L, L. The “PULL" rod c has
a cross frame with three upright bars c¹, c¹, c', behind the coins. When this frame
moves it carries the coins P with it, and the centre coin carries with it the bar F which
actuates the taps as in Figs. 1 and 2. As the coins move forward the two outside ones
come against the pivoted clicks K K and turn them in passing. If the outside
coins are not there the projecting parts t, t of the frame F block against these clicks.
Fig. 28 shows an arrangement of taps for selling compound liquids.
B is a vessel for holding one kind of liquid brandy for instance and W may hold
water. V is a vessel of known capacity and V₁ of double this capacity. The right
hand arrangement shows the method of supplying brandy alone as before described.
If a mixture is required the coin is placed in the proper slot to turn both taps on W".
The ball-cock W₁ cuts off the supply. The contents of both vessels V and V₁ com-
municate with the "PRESS" tap before described. Communication between the
vessels V and V¹ is prevented by valves t,t as shown in the figure 14 and the tap E is
employed as shown in Figs. 1 and 2.
Fig. 14 shows another arrangement for supplying compound liquids. The right and
left hand parts marked 1, and 3 are for supplying each liquid separately. That
marked 2 is for supplying compounds. The taps attached to ball-cocks P and P¹
which are on arrangement 2 can be set to cut off sooner than the corresponding
taps to right and left so that equal amounts of liquid can be supplied in every case.
The tap E is employed as shown in Figs. 1 and 2 and communication between the
vessels P and P is prevented by valves t t.
Fig. 15 shows an arrangement of apparatus for heating liquids.
บ
When the secondary vessel is full and the ball cock at its highest position the
arm a comes into the path of B when it is pushed. The press B is within the machine
and can only be operated when the door is opened as before described. The press B
having been pushed against a the tap T is turned allowing gas to enter the jets R
where it is ignited by constant jet j When vessel is empty the ball cock and
arm a take the position shown in dotted lines and the arm a does not then come into
the path of B. The tap T is drawn into its cut off position by a spring.
Fig. 16 is a sectional elevation of so much of the machine as will serve to show a
method of delivering solubles such as sherbet. The door D being opened one or more
handles H, are shown for delivering the various ingredients. The stock of these is
kept in vertical cases S T. on pulling H the discharging piece d which is attached to c
sends a quantity of the material down the shoot h. This may rest on the ledge t.
When the bar c is drawn out the vertical bar K falls into the notch Z and the spring x

page_text: cannot replace the bar c.
When the door D is closed the bar B is drawn forward and
its beviled or curved end raises the bar K and allows spring a to draw H into its
normal position, only one dose can therefore be obtained each time the machine is
worked.
Fig. 23 shows a plan of a contrivance to be employed with that shown in Fig. 16
when more than one receptacle ST is provided in order that only one dose may be
supplied for one payment. K', K2, K³, are transverse bars capable of an up and down
but not of a to and fro motion and attached in a suitable way to some fixed part of
the machine. H1, H2, H3 are handles of rods c¹, c³, c³, communicating with receptacles ST.
The three transverse bars, when all the rods are in, rest on the said rods. The shaded
parts represent slots better seen in
Fig. 23 which shows a section of H³ and rod c³.
When H¹ is pulled out the slot Z' in c¹ comes under the bar K¹ which is then free
to fall in the respective slots Z on all the rods. The rods c³ and c³ are thus locked
and c can be pulled out the length of the slot Z¹ on it. In like manner when c² is
pulled out, cand c³ are locked and so on. The bar K shown in Fig. 16 is attached
to a cross piece K* so as to move all the transverse bars.
Fig. 26 is a side elevation and
Fig. 27 is a plan of the apparatus employed in brewing or making tea and other

As the "PULL" handle, the rod c the coin P and bar F are drawn forward the
lugs on the latter move the handle of the tap B allowing liquid to flow from V into
the heating vessel H. When H is full a ball-cock rises and cuts off supply by the
tap K. A pin moving in slot x on bar F turns on gas tap G at the same time that
tap B is turned on. The gas is ignited by constant burner n. It may be necessary
for the operator to hold out the "PULL" handle sufficiently long to allow the water
to boil. The heating vessel H may be furnished with tubes so that the contents may
be heated more quickly. When the water boils a second ball-cock E makes electric
contact and closes a current from the battery by the "BELL" through the coils of
the electro magnet M and vessel H. When the surface of the liquid in H is quiescent
no contact is made by ball-cock E. The armature n', n' above the magnet M is fixed
on the tap L which is turned on when the circuit is completed. This tap L is kept
open by stem O from the armature n¹ pressing the valve R to the bottom of the
vessel and holding there for a time. When the liquid boils the "BELL" rings, the
tap L opens and the liquid is discharged along the pipe i into the movable container Z
in the brewing vessel Y. The substance to be brewed is discharged by piece d down
shoot h. This piece d is at the end of arm a which is fixed to bar F so that the
substance is discharged at the same time that the gas is turned on and the tap B turned.
This substance is stopped at bottom of shoot h by shutter e. The container Z is hinged
at and has an arm standing in the path described by the pin p which is fixed in
bar F so that when the bar F is moved forward the container Z is made to rotate on
its hinge through an angle above 90° and discharge.the residue from the last brewing.
In the return path the edge of the container Z meets the click q on the hinge of the
shutter e and opens it. The substance in shoot thereupon runs into the container Z
and is ready for the hot liquid which enters from pipe i.
Fig. 24 shows another method of making contact on boiling.
Attached to vessel H is tube S containing mercury S₁ and fixed contact piece El
communicating with "BELL." The other end of the mercury communicates with
battery. When the liquid in H boils the mercury S rises being expanded by heat
received from vessel Hand touches the fixed contact piece El.
Fig. 25 shows another method of making contact on boiling.
Qis a valve on heating vessel H weighted or pressed down by a spring S adjusted
to a certain tension. The valve Q is connected to a lever Q pivoted at Q. When
liquid boils the pressure inside the vessel H raises the valve Q and causes the other
end of the lever Q" to make contact with contact piece E" which communicates with
the "BELL." The lever Q also communicates with the battery.
