PROVISIONAL SPECIFICATION,
Improvements in Automatic Machines Operated by the Action of a
Coin or Coins or Counters.
I, BENJAMIN WILLIAM WARWICK, of 134 Highbury Hill, London, N., Electrician
do hereby declare the nature of this invention to be as follows:-
My invention relates partly to improvements on the invention described in specifi
cation No. 1639887 and partly to improvements of more general application to
automatic machines.
I
1. I arrange the taps of the machine described in the said specification and shown
in figures 1-6 so that the liquid shall be delivered when the pull bar is out.
also have the specified quantity of liquid measured off in advance and contained in a
closed secondary receiver. This receiver if desired can be fitted with a safety valve
and may either be stationary or movable with pull bar.
I employ separate tanks for clean and dirty water, or I may use a direct supply
for clean water and allow the dirty water to run to waste.
The water to wash drinking vessel is discharged by placing the drinking vessel on
stand, the weight of which then turns on the water tap directly, or by lever action,
or other suitable contrivance.
The door is so balanced as to drop open when released. The door may be closed
by a spring or weight which shall come into operation when the pump piston begins
to descend. The internal space can be so arranged that the door cannot close unless
the drinking vessel is properly replaced.
To prevent the pump being worked repeatedly at one opening of door I have a
pin on the pulley which moves a bar with a passing click and then blocks; the said
bar being returned when the machine is operated with fresh coin.
Instead of having a small jet of gas constantly burning as shown in figures 17, 18
of specification No. 163987 I may use electric methods for lighting as, for instance,
by spark from secondary current of induction coil or by revolving electrophori
operated by pull bar.

page_text: The opening of the door may be utilized for turning on the gas for heating
urposes.
I
The coin slit may be closed by any of the following methods:
(a). An aperture in the tank is closed by a flexible membrane which distends
with the pressure of the liquid. Motion is taken from this to close the coin
slit when the tank is empty.
29
(b). A closed vertical chamber full of liquid contains a movable body with an
air chamber. This vertical chamber receives pressure from a membrane
which closes an aperture in tank. When the tank is empty the movable body
rises to the top of its chamber in consequence of the diminished pressure and
is there shown displaying the word "empty or other inscription of similar
meaning.
(c). A ball cock may be used in the clean or dirty water tank for the purpose.
(d). The swing of door may advance a rack plate and so close slit after a certain
number of operations.
(e). The tank when empty may swing and close coin slit.
(f). I may use a float in tank to actuate externally a diverting piece placed in
the path of a falling coin so as to make the coin drop onto and actuate a
lever or other contrivance so as to close the slit.
(g). The motion of this diverting piece may be taken from the movement of
the balanced tank as describe:l in (e).
When the tank is empty
(h). A spring valve may be placed under the tank.
the valve rises and may be made to close coin slit.
(j). An inverted chamber open to the liquid in the tank at bottom has a
balanced membrane at top. Variations in air density in this chamber due to
varying depth of liquid in tank operate a membrane so as to close coin slit
when tank is empty or nearly so.
may utilize the coin merely to liberate the door by any of the methods described
liberating the pull bar, and I may attach the operating apparatus to the door so
at when the door is pulled back the taps are turned as by the pull bar. The
elivery tap and the tap for the rinsing water can be so arranged that one is shut
hen the other is open. The weight of the drinking vessel when on stand' is then
mployed to keep the delivery tap shut.
II. To cause a pull bar to operate an automatic machine I use any of the following
ontrivances:
(a). The pull bar shall be normally blocked by an arm of a rocking bar resting
in a slot on the pull har. This arm is released by the weight of the coin
dropped into the other arm. The coin is at first detained by a spring till the
pull bar is drawn out so that a raised piece on pull bar shall raise the first
mentioned arm of the rocking bar still more. This movement causes the
other arm of rocking bar to press spring and so release coin. The pull bar
may be connected directly or indirectly with taps. This spring may also
when pressed release the bolt of the door of the machine described in specifi-
cation No. 1639887 or the coin in its descent may first push against an arm
of a bent lever the other arm of which is connected to the bolt of the door
and by this action release the bolt, or, the bolt of the door may be connected
with the rocking bar above mentioned and released with the release of the pull
bar.
(b). Or the pull bar shall have one or more pivoted clicks upon it arranged so
as to turn only in one direction. Normally when the pull bar is drawn the
clicks come against fixed stops which prevent motion, but when a coin or
coins are placed in the machine the coins turn the clicks and allow them to
clear the fixed stops.
(c). The click may be of the form of a bent lever one end of which locks the
pull bar but when the other arm is moved by the coin the first mentioned arm
is withdrawn from and releases the pull bar. This movement can be also
utilized to release the door.

page_text: (d). Or the coin or coins may be made to raise an arm or arms of one or more
rocking pieces pivoted on the pull bar which rocking pieces normally block
the pull bar by coming against fixed stops. The rocking piece rides over the
edge of the coin and thus allows the other arm to clear the fixed stop.
This motion as in the method last described may be also made to release the
door.
In these methods the pull bar when liberated and moved may turn on the
taps or draw another bar with the taps on it, or the clicks, bent levers, or
rocking bars may themselves be the handles of the taps.
(e). The coin or coins in their resting position may be used to turn the tap
handle directly when the pull bar is drawn out, and the further extremity
of the handle may be made when turned to push away the rocking bar which
blocks the pull bar. This method is specially applicable when it is desired to
obtain various kinds of goods at one operation.
The clicks and rocking, bars revert to their normal position when free by the
tion of a spring or other suitable contrivance.
The coins are kept from dropping into the coin receptacle by arresting pieces or
springs attached to or actuated by the pull bars or other moving part of the
paratus, and if the coin is required to do more than one action it is liberated from
ige to stage.
The coin slit may be closed by the following method :
Two elastic chambers are in communication with each other. On one the weight
the goods acts, and the other by suitable gearing causes the coin slit to be closed
hen the diminished weight of goods conveys diminished pressure.

Coin or Coins or Counters.
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:
My invention relates partly to improvements on the invention described in my
previous Patent No. 1639887, and partly to improvements of more general application
to automatic machines.
Fig. 1 is a front sectional elevation of the interior of a machine embodying some
of my improvements.
Fig. 14 is an enlarged view of the ball valve arrangement.
Fig. 2 is a side sectional elevation.
Fig. 3 is a plan of the actuating part of the apparatus.
Fig. 4 is a plan of cleansing apparatus.
Fig. 5 is a view of a portion of the front of the machine.
The coin K having been inserted in the slit A drops down the shoot J and on its
way strikes one arm X' of a lever pivoted at Y. The other arm of X¹ is thus
caused to raise the bar Z¹ and catch A2 of the door C. The door which is conveniently
transparent is so made as to swing open when the catch A' is raised. The 'coin K
after striking X¹ drops to the position shown in Figs. 2 and 3, resting on a piece M
attached to pull bar N. Fixed guides can be added to hold the coin upright in this
position. To M is pivoted a rocking bar L which passes over N and rests in a notch T
of fixed piece S. A stud U may be placed on N just behind this position of L.
When the rocking bar L is thus engaged with S the pull bar N cannot be drawn out.
But when the coin K is inserted as shown the rocking bar L is raised by it when
the pull bar N is drawn out, the pull bar N having a little free play. L is then moved
out of the notch T and the pull bar N is released. As the pull bar N is drawn out
it carries the piece M with it and allows the coin K to drop into the coin receptacle.
A convenient way of moving the pull bar N from outside is by the engine handle B
pivoted to the frame at O and attached to the pull bar at P. Qis a spring attached
to frame for restoring pull bar N to its normal position when the handle B is released.
When the door is opened access is obtained to a cup or other drinking vessel E
attached to a chain and weight F and resting on a drain plate D which is in one piece
with or rigidly attached to a bar S² pivoted to frame at U and continued in a collar Vi
surrounding piston E₁ of a pump F1 communicating with a reservoir of clean
water For other supply. The piston E¹ is raised by a chain D¹ attached to the pull
bar N. T is a spring tending to draw S¹ upwards. W is a small piece of wood
or leather or other suitable material attached to V₁ so that when S₁ is raised and V¹
consequently depressed it acts as a brake on the piston E¹. The pump communicates
by a pipe Jte K' a series of orifices round the drain plate D and to G another

page_text: series of orifices in the middle of the drain plate. The water flowing from these
orifices passes through L' and M on to a pan Nattached to a lever 01 pivoted at Piits
other extremity. Qis a rod or chain attached to O' and to R' an internal continuation
of the door frame. The door is pivoted to frame of machine at Q3, Q³. By means
of Qan attachment to pull bar N the handle R of a two way tap V is moved.
Y is the reservoir of liquid communicating by a pipe W with a secondary measuring
vessel Z. If desirable a one way valve M* can be inserted in the pipe W to prevent
return from the secondary vessel Z. X is an exit pipe from Z leading to H the exit
orifice or tap of the liquid (Fig. 5). When liquid under pressure is supplied it is desirable
to have the pipe X considerably expanded immediately before the tap or orifice H. The
two ways of the tap V are so arranged that when W is open X is shut and vice versa. A' is
a ball valve shutting off communication with the air chamber when the vessel Z
is full. A is attached to a rod J which moves up and down a tube G which is
fixed below within the vessel Z and expanded above as shown at B'. Hare orifices
in the tube. The ball valve A¹ should be made so as to be of specific gravity less
than the liquid, sufficiently rigid not to collapse under the pressure, and sufficiently
flexible to make a tight joint. R2 (Fig. 3) is a pipe leading from the vessel Z to
a membrane C2 which acts upon a lever D2 for the purpose of closing the coin slit
as is more fully explained in Fig. 6.
In these figures the arrangement is for the supply of liquids under pressure;
otherwise the reservoir Y must not be placed below the level of the vessel Z.
The mode of using the machine is as follows:
-:
The coin K is placed in the slit A and drops down the shoot J striking on its way
the arm and so raising the bar Z' and latch A2. The door drops open and the
operator takes the cup E and holds it under the orifice H. He then by the handle B
pulls the bar N. The rocking bar L rides over the edge of the coin K and is so moved
out of the detent T of fixed bar S. There is a little play of rocking bar L in the
detent T. The pull bar N being then drawn the piece Q2 attached to it turns R the
handle of the two way tap V. This closes the entrance pipe W and opens the exit
pipe X and the liquid flows.through H into the cup. When the pull bar N was
drawn out the piston E of the pump was raised by the chain D', and the valve G¹
opened and H shut. When the cup is taken from the drain plate the spring T¹ draws
up the arm S and depresses V. The brake W₁ consequently comes into play and
prevents the piston El descending. After drinking the cup is replaced inverted on
the drain plate D. Its weight depresses the arm S' raises V₁ and removes the brake W¹
from the piston E which consequently falls closing the valve Gland opening H¹. The
water in the cylinder F is forced through the pipe J¹ to the orifices K¹ and G, and
so cleanses the outside and inside of the cup. As the dirty water escapes through L
and Mit falls on the pan N¹. The momentum and weight of the water depress the
pan N and bar O¹ and cause the rods or chains Q to pull down R and close the
door C. As soon as the handle B is released the spring Q draws back the pull bar N
and allows the spring Y to turn the two way tap V so that the pipe X is closed
and opened. The liquid accordingly flows from the reservoir Y and fills the
secondary vessel Zagain. The ball valve A is forced against the orifice of the air
chamber and prevents the liquid flowing into it. The spring Y is so adjusted
that the return of the tap handle it is delayed a little after the return of the pull har N.
As the pull bar N returns the locking bar drops into the notches T which are so
made that can freely pass backwards but not forwards without the insertion of
a coin. This prevents two operations of the pull bar N by the insertion of only
one coin.
Fig. 6 is an arrangement of mechanism for closing the coin slit when there is no .
liquid in the secondary vessel.
When there is liquid in the secondary vessel pressure is cominunicated through the
pipe R2 and distends the membrane C. This then moves one arm of the lever D*
pivoted at and so draws the piece G2 on the other arm from the coin slit A. When
the vessel is empty the membrane C does not act on D and the spring L draws the
piece G over the coin slit A.

page_text: Fig. 7 shows another method of closing the coin slit.
The secondary vessel Z resis on a platform Z pivoted at K+ to some fixed part of
the machine. When there is liquid in Z the arm Z presses down upon the flexible
air vessel H2 and forces the air through the pipe 12 into and distends an upper air
vessel K². This acts on the lever D2 in the way described under Fig. 6.
Fig. 8 shows another method of closing the coin slit.
Here the liquid in Zacts directly on a membrane (placed beneath an orifice in the
bottom of the vessel. The coin slit is closed normally by the piece G³, but when there
is liquid in the membrane (2 is distended and acts upon an arm D² of a compound
lever pivoted at E², and removes the piece G² from the coin slit A.
Figs. 9-11 show an arrangement for preventing choking suitable for use when.
more than one coin is used to operate the machine.
Fig. 9 is an elevation of coin shoot with diverting piece open.
Fig. 10 is an elevation of coin shoot. with diverting piece shut.
Fig. 11 is an elevation at right angles to Fig. 10.
The coin K drops down the shoot 3, strikes in its descent a tongue S³ of a lever S²
pivoted at T2 and holds the diverting piece U2 in position across the shoot till
released. A second coin falls on this diverting piece and is diverted into shoot M*
which may also if necessary be fitted with a diverting piece. When more than one
coin is required to operate the machine the locking and liberating arrangement already
described in Figs. 1-3 and 11 must be repeated.
Figs. 12, 13. and 14 show a modification of the actuating apparatus. The fixed
coin is used but it is now the fulcrum and the tap handle is the lever moved. This
method is suitable in cases where more than one liquid is provided and it is desired
to give the operator a choice with one pull bar.
Fig. 12 is a plan of an arrangement. for two coins and two secondary vessels.
Fig. 13 is a similar plan with one coin inserted and the pull bar drawn.
Fig. 14 is a front elevation of the same.
The coin K drops down the shoot J and is supported by the shoot and the edge N'
of a frame pivoted at 02. The frame carries a holt 03 which passes through and locks
the pull bar N. The pull bar N can however be moved forward a little space when
the bolt O³ is inserted. When a coin is placed as shown in Fig. 13, the tap handle R
of the two way tap V is turned because the tap V is attached to and moves with the
pull bar N. The secondary vessels Z, Z, may also move with the pull bar N, but as
represented in the figures they are stationary and connected to tap V by flexible
tubing V2. As the fixed coin acts on one end of the tap handle R the other end
pushes against the frame N2, which moving on its pivot 02 withdraws the bolt 03 and
also moves from under the coin K and allows it to drop into the coin receptacle.
In Fig. 14 the dotted lines show the position of the frame N" when the pull bar N is
drawn out. When the pull bar N is drawn back the fixed pin W pushes the tap
handle R back into its normal position.
Fig. 15 is a front elevation, and
Fig. 16 a side elevation of an auxiliary arrangement to be attached to the pull
bar for delivering solubles with the liquid.
To the pull bar N is attached an up and down extension D³ which carries rests M
and rocking bars Las already explained. When a coin K is brought into the position
shown the rocking bar L passes over it on the pull bar N being drawn. The rocking
bar Lacts on a pin G³ on a plate E3 and raises the said plate which is pivoted to the
frame at F3 and carries a bar H³. When the plate E³ is not raised H³ locks into a
notch on N as shown in Fig. 16, but when the plate E³ is raised H³ takes the position
shown in the dotted lines and N can be moved. The rocking bar I then acting on a
pin J attached to a push piece K³ causes a package M³ of the desired soluble to be
discharged from the receptacle L³. There must of course be provided an additional
number of coin slits and shoots corresponding to the number of receptacles L³. If
desired the bar H³ can be continued as shown in Fig. 16 to form the catch A
of the door which may either fasten the door directly or as shown in the figure
act on a bolt Lt.
