Improved Coin-freed Apparatus for the Delivery of Liquids or
Substances.
We, FRANK HEPTON, of 40 Samuel Street, Woolwich, in the county of Kent
cashier, and ERNEST ALBERT TRAISH, of Gothic Villas, Pembroke Road, Tottenham,
in the county of Middlesex, gentleman, do hereby declare the nature of this invention
to be as follows:-
The object of our invention is the production of a machine for automatically
delivering liquids or substances upon the insertion of a coin or coins of predetermined
value and denomination into certain slits, or a slit or groove provided for that
purpose. The delivery of liquids may be so arranged that either a single liquid, or a
previous mixture of two or more may be caused to flow by the introduction of a coin
or coins into a slit or groove, or slits or grooves, or we may so arrange the mechanical
coin freed delivery that a powder or powders may be so delivered, or several kinds of
fluids may be delivered, the coin freed appliance being common to all the spouts,
pipes or other sources of delivery as aforesaid.
In carrying our invention into effect we provide a suitable slit or- groove, or
more than one, as may be required, wherein a coin or coins may be dropped when
it is desired to operate the machine or apparatus. Said coin or coins is or are
allowed to fall upon, and actuate a balanced tray or lever. We may arrange the
mechanism so as to cause the introduction of the coin or coins to release a push
valve or tap, whereby a quantity of fresh water may be drawn off for the
purpose of cleansing the drinking cup or vessel. The operation of opening this
valve or cock may release the coin and cause it to fall upon the balanced tray
herein before described,-which is prevented from yielding or tipping by a bolt or
catch. In some cases we may prefer that the water supply shall be free, and be
operated independently of the coin or coins. In such cases we so arrange the
construction of the coin passage that said coin or coins falls or fall upon the balanced
tray hereinbefore referred to, without any intermediate action.
A separate knob or series of knobs is or are provided upon the exterior of the
case of the machine or apparatus, upon each of which is printed or clearly set
forth, the name or indication of the liquid or substance intended to be taken. The
action of pulling or pressing one of these knobs causes the bolt or catch supporting
the balanced tray before referred to, to be withdrawn, thereby releasing the coin and
allowing it to fall into a suitable receptacle. Said balance, in the act of falling,
and releasing the coin, establishes an electrical contact, which completes an electrical
circuit and allows an electric current from a suitable battery or other source of
electrical energy to flow through an electro magnet, said current being suitably
controlled by a clock, so that the duration of the delivery or flow of any liquid may
be guaged and checked to correspond to any predetermined quantity. A lever, or
other suitable contrivance attached to the armature of said electro magnet is so
arranged as to free or release a wheel, which establishes a second electric
contact during the revolution thereof, and thereby completes another electric circuit.
The electro-magnet, herein before referred to, is caused to operate a combination of
levers and rods, which mechanically couples the knob or knobs to a valve or cock, so
that the latter is operated by said knob, said valve or cock being kept open by means
of a lever provided with a suitable catch, which falling, and engaging with a slot or
indent, retains said valve or cock. A second catch, pivotted upon the aforesaid
lever engages with the electrical contact herein before mentioned, and so prevents
said contact from being broken upon the return of the knob when released.
The valve allows of the flow of the liquid or liquids from a containing vessel or

page_text: reservoir into a measuring chamber or vessel, which is also provided with an exit
valve for discharging the measured quantity of fluid, said exit or discharge valve
being opened by the return of the knob, actuated by a spring or other equivalent
device for this purpose, said valve being closed when said knob is again pressed or
pulled as the case may be. The liquid or liquids, in measured quantities may now
be received into a suitable cup or drinking vessel, through a spout or other contrivance
leading from the measuring chamber. When the period of time, measured by the
clock hereinbefore referred to, has elapsed said clock is caused to open the electrical
circuit, thus, by means of suitable levers, catches or other contrivances, allows the
valve or cock interposed between the measuring chamber and the containing vessel,
to be closed by a spring or other device, and thus cut off the supply. We may
attach a device or contrivance to said clock so as to stop the action of the machine
altogether during prohibited hours, or we may arrange a checking mechanism in
connection with said clock for automatically recording the receipts of said machine
within a given time. The delivery of powders or substances is arranged by the
employment of the same combination of levers, magnets and the like, as bereinbefore
described, but a suitable slide or trap is substituted for the valves.
employ any number of knobs, and cause one or all of these to be released at the same
time by the introduction of a coin or coins into a slit or groove common to all, or
into separate slits or grooves. We also provide a float within the containing vessel or
reservoir, for the purpose of opening the electrical circuit when said reservoir is
empty, or otherwise indicating to an intending operator that the machine is no
longer to be used.

Improved Coin-freed Apparatus for the Delivery of Liquids or
Substances.
We, FRANK HEPTON, of 40 Samuel Street, Woolwich, in the County of Kent,
cashier, and ERNEST ALBERT TRAISH, of Gothic Villas, Pembroke Road Tottenham,
in the County of Middlesex, Gentleman 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 our invention is the production of a machine for automatically
delivering liquids or substances upon the insertion of a coin or coins of predetermined
value and denomination into certain slits, or a slit or groove provided for that purpose.
The delivery of liquids may be so arranged that either a single liquid, or a previous
mixture of two or more, may be caused to flow by the introduction of a coin or coins
into a slit or groove, or slits or grooves, or we may so arrange the mechanical coin
freed delivery, that a powder or powders may be so delivered, or several kinds of
fluids may be delivered, the coin freed appliance being common to all the spouts,
pipes, or other sources of delivery as aforesaid.
In order that our invention may be clearly understood, we have appended the
accompanying four sheets of drawings, of which the following is a description.
Figure 1, Sheet 1 is a front elevation of the complete apparatus, and Figure 2 is
a section of the same upon A B.
Figure 3, Sheet 2 shews the arrangement for the reception of the coin or coins,
and the electrical contacts in connection therewith, and Figure 4 is a plan view of
the same.
Figure 5, Sheet 2, shews the electro-magnetic appliances for automatically delivering
a predetermined quantity of liquid from a tank or reservoir.
Figure 6 is a plan view of the same.
Figure 7 Sheet 3 shews a modification of the apparatus according to our invention,

page_text: for the delivery and regulation of liquids under great pressure, such as mineral
waters, and aërated drinks. This, in order to render the subject more clearly, is
drawn to an enlarged scale, relatively to the other views.
Figure 8, Sheet 4 shews a modification whereby the delivery of the liquids in
different quantities depends upon the weights and corresponding values of the coins
placed in the slit or groove.

Figure 13 is an elevation of a part of the above.
Figure 14 illustrates the automatic device adopted by us for the purpose of stopping
the use of the apparatus at a certain pre-arranged time, and opening the same again
at a given time.
In carrying out our invention we provide a shoot or trough a Figure 3, Sheet 2.
in connection with the slit or groove in the front of the case. A coin being placed
in said slit, slides down the trough or shoot a and falls upon the scale pan b, balanced
upon a fulcrum or pivot c. Said scale pan is deflected by the weight and impact of
the coin, and causes the contact pin d to establish an electrical circuit through the
spring e, which operates the electro magnetic device for the delivery of water only.
Said coin, by the depression of the scale pan; then drops into the shoot a', from whence
it falls into a second scale pan f, which, however is prevented from tilting under
the weight or impact of the coin by the locking bar ii. The knob g being now
pressed inwards, the locking bar ii is raised, and the deflection of the released
scale pan due to the weight of the coin upon it, establishes an electrical circuit
through the electro inagnetic apparatus which regulates the delivery of the beverage,
hereinafter to be described. Said electrical circuit is partly established by the
contact 1, due to the movement of the vertical lever h by the knob g being pressed
as before stated, and partly due to the contact pin touching the spring k, when
the cale pan fis released, and deflected by the weight of the coin. Said coin is then
allowed to fall into a suitable receptacle.
Referring now to Figures 5 and 6, Sheet 2, we wish it to be understood that C is
a reservoir, and D a measuring tank, and two or more complete sets are provided in
the apparatus. One set, as shewn, holds pure water in the tank or reservoir C, which
may or may not be connected to the ordinary watermain, by means of a ball cock, or
float valve. The smaller vessel D is a measuring tank, allowing a predetermined
quantity of liquid to flow at one time. The first reservoir and measuring tank
holding water, is connected to, and operated by, the circuit established through the
contacts de Figure 3, Sheet 2, so that the operator may obtain a certain quantity
of water for the purpose of cleansing the cup or other vessel attached to the front
of the apparatus for the reception of the beverage. Another set, or any number
of sets, of tanks C and D, holding a beverage is or are provided, and are connected
to, and operated by, the electrical circuit established by the contacts & Figure 3,
Sheet 2. Separate sets of the whole of this last mentioned arrangement are provided
in connection with each set of tanks ( D Figures 5 and 6, corresponding in number
to the varieties of beverages, powders, or the like comprised in the delivery of the
machine. In the case of several sets, as above referred to, we provide only one such
set for the delivery of water, connecting the whole of the contacts e d Figure 3,
Sheet 2 in "parallel" or "multiple" so that each or any of them may operate the
valves for the delivery of water when a coin is placed in the slit appertaining thereto.
The manner in which the water or beverage contained in the reservoir or tank (),
Figures 5 and 6 Sheet 2 is delivered is as follows, that is to say;
An electric current is caused to flow round the coils of an electro-magnet E,
Figures 5 and 6, by means of the contact established at e dor kj Figure, 3, in the

page_text: manner herein before described. A beam G. pivotted at H carries an armature F,
which is attracted by the electro-magnet E, and G is thus deflected, closing the
valve I in the outlet of the measuring tank, and opening the valve J, thus admitting
a fresh supply of water or beverage into D. As the duration of the flow of the
electric current round the coils of the magnet E is short relatively to the time
required for the flow of a definite quantity of liquid from the reservoir C into the
measuring tank D, we provide a catch or trigger K pivotted at M, which engages
with a pin fixed in the beam G, and retains the latter in its deflected position after
the current has ceased to flow round the coils of the magnet E. A spiral spring,
or equivalent device serves to maintain the trigger K in contact with the pin
upon G and also to cause it to become locked when G is deflected. In this position
of the various parts of the device, the liquid in C is allowed, by the opening of the
valve J to flow into the measuring tank D. A desired quantity of said liquid is
regulated by means of an adjustable float N, which may be moved or adjusted to
measure off any predetermined quantity. When the desired level of liquid is attained
in D, the rising float N establishes electrical contact at O. P, and completes the
electrical circuit through the coils of an electro magnet L, which, attracting a suitable
armature attached to the lower end of the trigger K, moves the latter upon the
pivot M so as to release the beam G. A spring, weight, or the like, now causes G
to assume its normal position, closing the valve J, thereby shutting off the supply to
the measuring tank D, but at the same time opening the outlet valve I, and allowing
the measured quantity of liquid to flow through the pipe Q to the spout or nozzle in the
front of the machine. The principal parts comprised in the foregoing description and
shewn by Figures 3, 4, 5 and 6 Sheet 2, may be identified by similar letters of
reference, in position, in the sectional elevation Figure 2, Sheet 1.
We do not confine ourselves to the particular conformation of the external case
shewn by Figure 1, Sheet 1, nor to the especial arrangement of the various parts
shewn by Figure 2, upon the same sheet.
In Figure 1, above referred to, the knobs 1 and 2, corresponding to the spouts or
nozzles 5 and 6, are for the delivery of two beverages, two separate money slots 3
and 4 being provided, one for each kind. The spout, or nozzle marked 7 is for the
supply of a certain quantity of water for cleansing the cup 8, and, although we may
arrange any number of similar appliances for the supply of various beverages in one
case, we prefer to employ one nozzle for the delivery of water, common to all. The
two semicircular spaces 9, 9, may be employed for the exhibition of moving
advertisements, which may be operated by the clock work, forming a part of our said
invention. In Figure 2, Sheet 1, 10 is a suitable drain pipe, leading from a sink to
a drain, and 11 is a battery of galvanic cells of sufficient power to work the various
circuits.
In cases where we wish to adapt the apparatus according to our invention for the
delivery of mineral or aërated waters, or liquids under great pressure, it is evident
that certain modifications are necessary. In the first place, we dispense with the
measuring tank before described, for the reason that the How of liquid under pressure
would cause the action of the adjustable float to be irregular, and secondly, said
pressure would render the electro-magnetic regulation of ordinary valves impracticable.
Therefore, we employ the modified arrangement shewn by Figure 7, Sheet 3.
A coin being placed in the slit or groove, slides down a suitable trough or shoot
upon the scale pan A, balanced by a weight q and pivotted at a.
Said scale pan is
however locked by the bent locking bar B, pivotted at b, and cannot be deflected by
the impact or weight of the coin until released. If no coin be allowed to fall upon
the scale pan A, the knob K may be pressed inwards, and recoil by the action of the
spiral spring y without causing the liquid to flow, because the rod H, sliding within
the block W, acts as a distance piece when raised as shewn by the dotted outline, and
allows the slide J to move and operate the valves N by the movement of I, and also,
the electrical contact at c and d forms part of the circuit only, which must be fully
established at p and o by the weight of a coin before the slides I and J are
mechanically connected. If, however, the knob K te pressed inwards when no
с

page_text: contact is established between o and p the tension of the spring y, and the horizontal
movement of the distance piece or block H within the block W, serves to return said
knob when the pressure is released.
When the coin, however, is dropped upon the scale pan A, and the knob K pressed
inwards sufficiently to make contact at c d and at the same time pressing forwards
the locking bar B by the lug fattached to the slide I the scale pan A is released,
and is deflected by the weight of the coin, so as to complete an electrical circuit
between the contacts o p, and passing round the coils of an electro magnet Q
deflecting the armature R, pivotted at and establishing a second electrical circuit
between the contact spring and pin s and contact bar t. This second circuit includes
the coils of the electromagnet C, and this when magnetized by the passage of the
current, attracts the armature fixed to the lever E, pivotted at e, which pressing
against the spindle F, working in the guide G, raises the distance piece er block H
between the slides I and J. When J is impelled forward by the pressure of the
hand upon the knob K sufficiently to allow the catch or trigger m to engage with the
notch n, the slide J is retained against the tension of the spiral spring M. indepen-
dently of the continuation of the pressure of the hand upon the knob K, for a certain
space of time, during which the liquid passes from O under pressure, through the
equilibrium valve N, to P, leading to the spout or nozzle in the front of the machine
whence it may be received into the vessel provided for that purpose. Now, since the
flow of liquid depends upon the release of the trigger m from the notch_n, which is
performed by the free end of the lever E striking the end of the lever L when the
current is interrupted in the coils of the magnet C, it is necessary to maintain
the circuit including said coils unbroken while sufficient liquid passes through the
valve N, and such maintenance of the circuit must not in any way depend upon
the pressure upon the knob K, since this may be released when said liquid has
commenced to flow. We attain this by the employment of an ordinary clock S,
the escapement or other rapidly moving spindle of which actuates a vertical
spindle a by means of bevil gear T, or any other suitable mechanism. A disk u¹ is
attached to the spindle and rotates with it, and upon the upper surface of said
disc u¹, we fix a projecting pin v. A second disc u fits loosely upon the spindle a so
that it may freely slide up and down when raised by the forked end w of the lever R',
or allowed to fall. One or more holes are formed in the disc u so as to coincide with
the pin in the lower disc u¹. Now, when the end of the lever R¹ is raised by the
momentary action of the electro-magnet Q, the disc u is raised, and the pin.v
disengaged, so that the disc u, being free upon the spindle a no longer rotates with,
or by means of, the lower disc u¹, and is retained in its raised position until the
uniform rotation of the disc u¹ by the clockwork, causes the pin v to again coincide.
with the hole, or another similar hole in u. Therefore, as the magnetic action of C
is maintained while t and s are in electrical contact, independently of the continuation
of the electro-magnetic activity of Q, it is evident that the duration of said contact,
and consequently the flow of the liquid, depends upon the distance apart of the holes
in the disc u, or the rate of the rotation of the disc u', these being conditions which
may be varied according to the requirements of each particular case.
The second positions of the chief parts shewn in Figure 7, Sheet 3, are indicated.
by the dotted outlines.
In some cases it is advantageous to be able to draw different quantities of liquid
from the same reservoir and measuring tank, corresponding to coins of different values
and weights. In carrying this into effect we use, in connection with the reservoir
and measuring tank, and the fittings appertaining thereto, as hereinbefore described,
the electro-magnetic device shewn by Figures 8, 9, and 10, Shent 4.
Under the ordinary method of operation, the introduction of a coin of the full
value into the slit, would cause the measuring tank D to be filled through the pipe
or conduit B until the top of the rod C, being moved up by the float A, makes
electrical contact with E, which stops the supply to the measuring tank D from the
reservoir in the manner bereinbefore described with reference to Figures 5 and 6,
Sheet 2. It is necessary, therefore, that a corresponding contact should be made
I

page_text: before the float A has attained the full range, when a coin of a lower denomination
or of less value is placed in a separate slit, which with the necessary balanced scale-
pan, electric contacts and the like is provided. Referring to Figures 8 and 19,
Sheet 4, which are elevational and plan views of the device, respectively, the
dropping of a coin of, lower denomination into the balanced scale pan provided for
it, causes an electrical current to traverse the coils of the magnet F, attracting the
armature G, which is attached to a lever H, pivotted at g. The deflection of said
lever H therefore causes the second contact screw or pin e to be moved over so as
to coincide with the float contact C, and thus stop the supply of liquid to the
measuring tank D, when a quantity of fluid is held therein corresponding to the
coin of lower value before mentioned. As the duration of the flow of the electrical
current round the coils of the magnet F is maintained only while the coin
momentarily rests upon the scale pan, we provide a locking bar I, shewn detached,
and drawn to a larger scale in Figure 9, Sheet 4. Said locking bar I is pivotted
at K and also at L, and when the lever H is moved by the magnet F in the manner
above described, the notch J firmly retains said lever against the tension of the
springs when the action of F has ceased. The descent of the float causes the
contact plate to strike the trip-catch M, and thus tilting the locking bar I, lifts
the notch J so as to release the lever H, and allow it to be returned to its normal
position by the spiral spring s. Said trip-catch M allows the contact plate to pass it
when rising without imposing much resistance thereto.
In order to effect the coin-freed delivery of powders or the like, we employ a
modification shewn by Figure 11, Sheet 4, which is used in connection with the
coin shoot, balanced scale-pan, and electrical contacts hereinbefore described, and
shewn by Figures 3 and 4, Sheet 2. The electrical contact established by the
falling coin, completes a circuit through the coils of an electro-magnet N,
Figure 11, Sheet 4, and this, deflecting the lever O, pivotted at n opens the
flap valve V, against the tension of a spring v, and the powder, or other
substance filling the shoot S is discharged upon the balanced scale pan R,
pivotted at r. As the duration of the magnetic effect of the electric current in the
coils of the magnet N is momentary, and not sufficient for the delivery of the
required quantity of the powder or the like, we provide a locking bar P, fulcrummed
at p, and balanced by a weight 9 which may be adjusted along said bar to suit any
required quantity of powder, or other substance. This locking device holds the
valve V open until a certain quantity of powder or the like has fallen upon the
scale pan R, to depress it against the balance weight 9, which releases the lever O,
and allows the valve V to be closed by the action of the spring v, and at the same
time the depression of said scale pan R discharges the measured quantity of powder
or the like into a shoot, or receptacle to which the operator may have access.
apply this device in conjunction with one, or several sets of the liquid delivering
appliances hereinbefore described, in the same machine, or we may, according to
our invention, apply the same to a separate machine, intended solely for the coin-freed
delivery of powders solids, or semi-solids.
We may
It is highly essential, in apparatuses of this nature, that some intimation should
be afforded to intending consumers when a tank or reservoir of any particular
beverage is empty, therefore we have provided the automatic device shewn by
Figure 12 Sheet 4, in which C is a portion of any of the main tanks or reservoirs,
holding the beverages. A float F is freely attached to a chain c of such length as
to support or carry the weight of the float F when the latter is no longer supported
by the liquid in the tank C, by reason of the diminution of level by usage. Said
chain is attached to one end of a balanced lever L, which carries a plate P at the
other end, suspended thereto by means of a wire or equivalent. Said plate P is
opposite to an opening or slit in the front of the case, marked with the designation of
the liquid in the tank C. The plate P is twice the depth of the opening or slit
aforesaid, and the upper part is blank, or otherwise, and the lower marked by the
empty" or otherwise signifying the same meaning. When the level of the
liquid in the tank C falls so as to impose the weight of the float F upon the chain c,
word "

page_text: the lever L is deflected, and the word or signification marked upon the lower part of
the plate P is raised and exposed to view through the opening or slit, as shewn by
Figure 13, Sheet 4.
We may provide each of the tanks or reservoirs with this
device, and may further modify it so as to cause the plate P to close the opening of
any money slit when the tank appertaining thereto is empty.
It may also be necessary, in certain cases, to close the money slits in the machine
for a certain period of time each day, and that the opening and closing thereof should
be automatically performed. For this purpose we provide a clock a Figure 14,
Sheet 4, the train of which causes a disc to revolve once in 24 hours. Said disc b
is furnished with a notch or recess c upon its circumference, into which the end of
the lever d may drop when the rotation of brings said notch e directly under it.
The lever d dropping in consequence, an electrical contact is established between e
and f, which completes an electrical circuit round the coils of the electro-magnet g.
The lever h, pivotted at i, is then raised, lifting a shutters which effectually closes
the money slit. The end of the lever is a slotted or notched quadrant, which
enables the locking bar j, by the action of the spiral spring k to lock the shutter s in
its closed position. A contact breaker, included in the circuit of the electro magnet g
may be operated by the movement of the locking bar ; so as to prevent waste of the
electrical energy, by breaking or interrupting the circuit aforesaid. The disc is
attached to the spindle of the clock train by means of a thumb uut n, or any other
similar device whereby it may be adjusted. so that the notch c may bo opposite to
the end of d at any desired time of the day or night, and thus effect the automatic
closing of the money slit. In order that the shutter may be lowered, and the money
slit again uncovered automatically when desired we provide 24 holes round the edge
of the outer face of the disc b, into one of which a pin p may be placed; the position
of each bole representing one hour, so that the pin p may be placed to correspond
with the hour at which it is wished to open the slit. When this hour has arrived,
the pin p pressing upon the spring contact m completes an electrical circuit round
the coils of the electro-magnet which releases the locking bar j and allows the lever /
carrying the shutter s to fall, thus opening the money slit. In this manner, and by
these means we are able to accurately adjust the position of the disc b relatively to
its spindle, and the pin p in one of the holes around 6 so that the machine may
become closed or inoperative for a given or prearranged number of hours, and the
opening and closing thereof may be performed automatically.
We may also, in certain cases apply to the machine constructed in accordance with
our said invention, any suitable device for registering the amount of money collected
in a given time, but we wish it to be understood that we do not confine ourselves to
the attachment of this latter device, nor any of the modifications herein before
described, to the machine shewn in elevation by Figure 1, and in section by Figure 2,
Sheet 1, but we may add each or any of said modifications thereto, and in combination
therewith for the various purposes as set forth.
Having now particularly described and ascertained the nature of our said invention,
and in what manner the same is to be performed, we declare that what we
claim is;
First. The coinfreed apparatus for the delivery of liquids or substances sub-
stantially as herein described and shewn by the accompanying sheets of drawings.
