PROVISIONAL SPECIFICATION.
Improvements in Coin-freed Automatic Delivery Machines.
I, BENJAMIN WILLIAM WARWICK, of 134 Highbury Hill, London, N., Electrician,
do hereby declare the nature of this invention to be as follows:-
The essence of my invention is the utilising the weight and momentum of the sub-
stance delivered to effect its own delivery.
In the case of liquids I have the measuring vessel pivoted so that when it contains
the right quantity it will tilt over and discharge either immediately or through another
channel. When this has taken place the measuring vessel is retained in this position
by a catch and is liberated by a coin striking an arm attached to the catch. The
measuring vessel receives the liquid from a tank or reservoir and carries the arm of a
tap or valve which shuts off communication with the tank when the vessel tilts over to
discharge, and opens when the vessel swings back.
To adapt this contrivance to the supply of liquids under pressure it may be desirable
to have an additional valve or tap to prevent the escape of the liquid from the measuring
vessel before tilting. This can be connected with the tilting part of the apparatus so
as to be open or shut at the right times.
For solids I have a pivoted delivery shoot operated by the weight and momentum
of the article supplied as already described, and also additional apparatus for putting
the article on the delivery shoot which additional apparatus should receive its motion
from that of the delivery shoot. Any suitable contrivance for converting vortical into
horizontal motion can be used for this purpose.
I do not limit myself to the method described of liberating the delivery shoot by
the coin but may employ any other suitable method of accomplishing it.
Dated this 12th day of February 1889.

COMPLETE SPECIFICATION.
Improvements in Coin-freed Automatic Delivery Machines.
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 essential principle of my invention is the utilizing the weight and momentum
of the substance to be delivered to effect its delivery in a coin freed machine.
With the aid of the accompanying drawings I show methods of carrying out my
invention but I do not limit myself to the details therein shown. The same letters
represent similar parts throughout.
Fig. 1 is a front view of the outside of the machine.
Fig. 2 is a front view of the machine with the front portion of the frame removed.
Fig. 3 is a side view of the machine with the side frame removed.
Fig. 4 is a view showing the measuring and delivery apparatus on a larger scale.
A is a reservoir of clean water for cleansing the drinking vessel and feeds into
a measuring vessel B through pipe C. The vessel B is pivoted to the plug
of the tap D and has attached to itself an adjustable weight E so that
when empty the exit channel of vessel B is tilted upwards and the tap D is open.
When the desired quantity of water has passed into B from A, the weight of B
and water combined tilts the vessel B downwards and the water is discharged into
vessel J which is pivoted at G and furnished with a crank F on pivot G. The vessel B
D
1

page_text: is retained in this downward position by the catch K' of tongue K pivoted to coin
shoot Mat Land projecting into the coin shoot as shown. The catch K acts on N³,
a pin atinched to vessel B. When the vessel B is tiltod downwards the tap D is
closed. N is the reservoir of the liquid to be supplied to the operator in the cup Q.
This liquid is delivered in the way already described through the pipe W¼ into the
measuring vessel () and through pipe P into the cup Q.
The coin is inserted into the slit R and falling down the shoot M strikes the
tongue K and so withdrawing the catch K from the pin N liberates the vessel B,
which is then tilted upwards by the weight E and the tap opened. The water
then flows from A through into B until the additional weight in B causas it
to tilt downwards and discharge its contents into J. The coin in its further
descent strikes against the tongue K' which projects into the shoot M and is
pivoted to it at 17. The outer end of this tongue is attached to a chain A' which
at its other end is attached to the catch B of the door T. The door T is pivoted
to the frame of the machine and is so made and balanced that when the catch H²
is raised it swings downwards and so raises the bucket F', which is attached to
inner arms of the door by rods or chains II. When the coin strike, tho
tongue K the chain A and the catch B are moved upwards so that the door T
is released and swings open lifting the bucket at the same time. The operator
can then get at the cup which he places ander the orifice of the pipe P. The
coin in its further progress down the shoot M strikes against the tongue K³,
which also projects into the shoot M and is pivoted to it at I. The catch Kis
thereby withdrawn from the pin N, which is attached to vessel O, and the vessel O
is accordingly tilted upwards by the counterbalancing weight and communication
is opened between the reservoir N and the vessel O in the manner already
described. When the required amount of liquid has passed into the vessel 0 it
descends, closes the pipe W, and empties its contents through into the cup Q.
When the operator has emptied the cup he places it inverted on the drain plate U.
The drain plate is pivoted to the back of the frame at W by rods V which are
hold upwards by springs X attached to some fixed part of the machine. The
weight of drain plate is just sufficient when the cup Q is placed on it to depress
the rods V. To one of the rods V is attached a chain Y, which at its other
extremity is fastened to the crank of the vessel J. When the cup Q is then
placed on the drain plate U, the vessel J is tilted over and discharges its contents
into the wide mouth of pipe A'. The cleansing water descends the pipe A', which
lower down dividos into three channels, the central channel serving for cleansing the
interior of the cup and the two side channels for cleansing the exterior of the cup in
the manner described in my previous patent No. 7275 dated May 16th 1888. The
cleansing water passes through drain plate U and channel E' into the bucket F¹ till
the weight and momentum of the water cause the bucket F' to fall, and by means of
chain H shut the door T. The cleansing water is poured into vessel Y¹ or flows away,
and the coin drops into receptacle (*. In Fig. 4 the multiple catches K, K' show a
device where more than one coin will be required to liberate the measuring vessel.
I do not limit myself to the method here described of liberating the measuring vessels
but may use a pull bar as described in my previous patent already referred to or any
other convenient method.
Fig. 5 shows a modification of the delivery apparatus suitable for the supply of
liquids under pressure.
When liquids under pressure are supplied the reservoir may be placed in any part
of the machine. The vessel O is furnished with adjustable counterbalancing weight
and is tilted and liberated in the manner already described. But instead of being
pivoted on the tap, it is pivoted to some fixed part at 1 and is furnished with a pin or
stund which acts upon the handle of the spring valve D in the supply pipe W.
When the vessel O is released and is tilted upwards, the pin E forces down the
valve D and allows liquid to flow through W into O. When the vessel O is tilted
downwards the pin E³ does not press on the arm P', and the pressure in the pipe W
keeps the valve D³ shut.

page_text: Fig. 6 shows a more perfect form of the measuring apparatus for the supply of
liquids under pressure
The vessel is held pivoted at G³ to some fixed part and has counterbalancing
weight E. It is furnished in addition to the supply valve D with a delivery valve Q
and a snifting valve R¹. S, T, U₁, are fixed pins acting on the handles of the
respective valves. When the vessel O is liberated and swings upwards as shown in
the drawing the pin U₁ presses on handle of valve D2 and opens the supply pipe W¹.
The pressure in vessel Othen keeps the valves Q' and R' shut. When the required
quantity of liquid is supplied into O, it swings downwards and the handle of valve D'
is removed from pin Ú, and the inflow through W is stopped. At the same time
the pins S¹ and T open the valves Q1 and R allowing the liquid to flow from
vessel O and the excess of gas to escape above through the snifting valve It'. _Fig. 6A
shows more clearly the handle of valve D2 pivoted at M' to the fixed bracket I^.
Fig. 7 is a modification of Fig. 5 showing how two or more liquids can be introduced
into the measuring vessel.
In addition to the parts shown in Fig. 5 the vessel O is shown attached at B³ to the
handle J³ of tap in pipe Os leading from additional reservoir M³ to O. The parts are
so arranged that when O is tilted upwards the pipe O' is open, and when O is tilted
downwards the pipe O³ is shut.
Fig. 8 shows an arrangement in which the liquid to be delivered is held stored
ready for instant delivery.
The measuring vessel O acts in the manner already described, but instead of
pouring its contents directly into the exit pipe P, it pours them into a vessel P³.
This vessel P3 is pivoted at Gs to some fixed part, has counterbalancing weight E,
and swings freely on its axis. The vessel P3 is detained and liberated in the way
already described in connection with the vessel O. At the beginning of operating
the machine P is full and ready to descend as soon as liberated. As it descends
the rod Q which is fixed to the axis of P' strikes against the fixed pin R³ 30
that the vessel P³ which would otherwise retain its former position is tilted over and
immediately empties its contents into P. Being empty it rises to be filled ready
for the next operation.
Fig. 9 shows an arrangement in which the liquid to be delivered is hold ready for
instant delivery under pressure.
In this arrangement there are two measuring vessels O, pivoted, counterweighted,
and otherwise fitted as shown in Fig. 6. The upper vessel Ó holds the liquid
ready for instant delivery. The lower vessel O is empty. When the machine is
operated the catch K is withdrawn from the pin N and the full vessel O falls and
delivers its contents and is kept in the downward position by the catch K' as
already explained. When the empty vessel O is liberated it rises into the position
shown in dotted lines to receive the supply from reservoir and then falls into the
position with pin N³ resting on catch K. This fall is sufficient to close the supply
pipe.
Fig. 10 is an elévation of an arrangement for the delivery of solids.
Fig. 11 is a view of part of the same.
The goods are shown stored in shoot 73. The delivery pan A* is pivoted at F³,
and counterweighted at E. N³ is the pin secured by catch in coin shoot as already
described. A vertical bar D is on the bar of the delivery pan at the pivot F³.
To the ends of this bar D' are jointed rods Y' whose other ends are jointed to
horizontal bars H* which themselves are jointed to supporting rods X³. The rods X³
are pivoted at fixed parts C. The bars H' carry rollers W, which when the
pan A is in the downward position as shown support all the packages in Z³. At Et
in lever of pan A' is fastened a rod B₁ attached to the toggle joint S³, S³, one
end of which joint is hinged to frame at T3 and the other end is attached to swing
piece U³ which is pivoted to shoot Z³ at V³. When the pan A₁ is released by
coin it swings up and at the same time the rollers W³, W³, move into the position
shown by dotted lines, and the bottom package is deposited in pan A*.
The toggle
joint S³, S³, is also straightened and the piece U³ holds firmly up the other

page_text: packages in shoot 2. The pan A and package overbalance the weight E and the
pan descends and delivers the package and is locked till the next operation in the
manner already described.
Fig. 1 shows more clearly the attachment of rod D' to lover of pan A'.
