I, SAMUEL SEALY ALLIN of 52 Woodstock Road,. Bedford Park, in the county
of Middlesex, Gentleman, do hereby declare the nature of this Invention to be as
follows:-
The objects of this invention are ; to simplify the construction of automatic machines
by substituting stronger and simpler mechanism not liable to derangement and
certain in its action, for the more complicated and unreliable machinery generally
used; to enable one set of mechanism to effect the delivery of many kinds of goods,
both solid and fluid, and especially to make automatic machines adapted to the
supplying of drinks and food for general consumption.
The system on which I construct my machines is that of causing the coin, or its
equivalent, usually deposited, only to unlock the action, leaving the buyer to do the
work, and I dispense with a delivering slide, and get rid of all the functions usually
connected with it. The machine consists of a case whose size and shape varies
according to the quantity and number of the various kinds of goods it is intended to
distribute, and as I consider that it will be most largely used for the supply of drinks,
as tea, coffee and cocoa, which require to be kept hot, and of effervescing fluids and
filtered iced water, which require to be kept cool, I describe briefly a machine
constructed with this object.
On the front of the case is a dial having all round it the names of the various
goods obtainable and from its centre lines radiate, one pointing to each name.
In the centre is a handle having close to the dial a pointer. These are fixed to a
round bar passing through the centre of the dial into the interior of the machine, and
are free to turn and to cause it to turn with them.
On the inner end of this bar is an arm fixed on behind the pointer, so that when
the pointer is moved round to any name the arm stands exactly over a lever, that, on
being moved by it, effects the delivery of the goods desired from the receptacle or
vessel that contains them.
The bar is carried in a bush in the front plate of the machine, and besides turning,
can, when released, be drawn out a certain distance.

page_text: Close to the arm and between it and the back of front plate a hollow collar is
fixed on the bar. Inside this a helical spring is coiled round the bar and pressing
against the front plate keeps the bar and arm held inwards. This collar is shaped out
to receive the end of a detent connected with the coin lever which prevents
the bar being drawn forward until the detent is withdrawn by the deposit of
a coin.
On the back of the front plate is fixed a guard ring, a circle or part circle of metal
of several inches diameter round the bar as a centre and standing out so high that
the arm in being moved round just clears it.
The object of this is to prevent the arm being drawn forward except when
exactly over some one of a series of levers. These levers lie in spaces cut out of
the metal ring and ordinarily stand level with it. They are placed radially, or
nearly so, round the bar and correspond to the lines on the dial. To the end
of each is attached a link connecting it with the arrangement for delivering
the goods. This must vary according to whether solids or fluids are in
question.
With solids any convenient mode of storage may be adopted, but I prefer placing
each kind, either in a coiled spiral travelling carrier, or what is still more simple, in
a horizontal compartment end on to the lever and carrying them on an endless band
(similar to that frequently used for the conveyance of grain) passing round a roller
at each end, that at the front end next the lever having a ratchet wheel, and by it
is mounted a swinging arm carrying a pawl. This arm is connected to the lever by
the link above mentioned and it is drawn forward when the lever is depressed and
moves the roller and band the necessary distance. It is so weighted that it falls
back after each stroke, and aids in returning the lever itself to its position after the
main arm on centre bar which depressed it is withdrawn by the helical spring. Each
stroke of the ratchet draws the band forward and throws off one article, which falis
down and slips out on to a tray on the front of the case. With fluids the arrange-
ment is different. Tea coffee and such are stored in removeable cisterns with a lid,
and effervescent fluids in hermetically closed vessels also removeable. The former are
in a compartment separate from the latter, and as they require to be kept hot, I fix
under each a gas burner, connected with a float arrangement in the cisterns which
shuts off the gas when the cistern is empty and indicates the fact on the dial. The
compartment in which these stand is enclosed all round, except where the gas burners
act, with nonconducting material to retain the heat. The vessels with effervescent
fluids are also in a compartment lined with non-conducting material, ice is placed in
this as in an ice safe, to keep them cool.
I preferably employ no measuring vessel or tap, external to the reservoir but in a
well at the bottom of each cistern or vessel, at the front end, I put a tube of
cylindrical or other shape of the required capacity open at both ends. One end
is fixed in the front of the reservoir from which it slightly projects. Through the
tube runs a rod in guides having at each end a valve, so fixed that when one is
open the other is shut. The rod projects beyond the outer valve and travels in a
guide. It has a helical spring to keep the outer valve closed and like the ratchet
above referred to is connected to the lever which moves it. On the outer valve being
opened, the contents of the tube run out into a receptacle from which they are
drawn off and the inner valve is closed and kept tight by the motion of the rod and
the pressure behind it. To unlock the action I use the ordinary rock lever, made
long so as to be sensitive and weighted at the short end with an adjustable weight.
To this lever is attached the detent, which engages with the collar on central bar.
The collar and detent are so shaped that the depression of the rock lever by the
weight of a coin permits the bar to be drawn forward. When this is complete the
coin rolls into a receptacle where it remains visible till the next one is deposited ;
arrangements for indicating numbers, ringing a bell showing "empty" and closing
the money slit are easy to adopt if desirable.
The coin, as usual, runs down a guide on to the rock lever, but I use a check at
bottom to prevent impact and make the weight alone act, and I make the lever

page_text: capable of being actuated to withdraw the detent by a coin of less weight, by
causing the lighter one to bear on it at a proportionately greater distance from the
fulcrum.
On the front beneath the dial I place nozzles for the several fluids, which when
previously drawn from the reservoirs by the central handle, are obtained by a tap,
push-button, or other suitable device. Beneath the nozzles is a swing basin, which can
be folded up or taken out of the way when the machine is closed, and at the sides are
trays to receive solids as drawn from their compartments.
I propose to combine with the supply of liquids and food for payment, "a gratis
supply of drinking water.
I provide a set of drinking cups kept in enclosed cabinets with glass doors, which
close with a spring and are released by the action of the central bar when delivering
any fluid. These cups would be secured to the front by chains.
I provide also sliding or swing doors to shut up the machine at night, or when not
in use.

page_text: I, SAMUEL SEALY ALLIN, of 52 Woodstock Road, Bedford Park, 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 main objects of my invention are; to simplify the construction of automatic
machines for delivering articles in exchange for coin, by substituting stronger and
simpler mechanism, not liable to derangement and certain in its action, for the more
complicated and unreliable machinery generally used; to enable one set of mechanism
to effect the delivery of many kinds of goods, both solid and fluid; and especially to
make automatic machines adapted to the supplying of both drinks and food for general
consumption.
The system on which I construct my improved machines is, broadly, that of causing
the coin, or its equivalent usually deposited, only to unlock the action, leaving the
buyer to do the work, and I dispense with a moving delivering slide, and get rid of all
the functions usually connected with it.
The machine is contained in a case, the size and shape of which vary according to
the quantity and number of the various kinds of goods it is intended to distribute,
and as I consider that it will be most largely used for the supply of drinks, such for
instance as tea, coffee, and cocoa, which require to be kept hot, and of effervescing
fluids and filtered iced water, which require to be kept cool, I will proceed to describe
a machine constructed with this object, as illustrated in the accompanying nine sheets
of drawings.
Fig. 1 is a perspective external view of the machine; Fig. 2 is a front sectional
elevation through the line Z Z in Fig. 3; Fig. 3 is a side sectional elevation through
the line Y Y in Fig. 2; Fig. 4 is a side sectional elevation through the
centre line X X in Fig. 2; Fig. 5 is an elevation of a portion of the delivering
mechanism behind the dial to an enlarged scale; Fig. 6 is an elevation of the coin
shoot and coin lever behind the dial to an enlarged scale; Fig. 7 represents, to an
enlarged scale, the mechanism behind the dial as shewn in Fig. 4, through the line W W
in Fig. 6 many details being omitted in Fig. 4 to avoid confusion; Fig. 8 is a full-
sized sectional elevation of the measuring apparatus for beverages attached to each
cistern Fig. 9 is an enlargement of a portion of Fig. 4 shewing the cases for
solid goods, and Figs. 10 and 11 are detached views of parts of the mechanism of the
said cases.
Similar letters of reference denote similar parts throughout the drawings.
The machine has an external case A, preferably of cast iron, provided with suitable
doors A1, A2, A3, A4, in the front, back, and sides, for obtaining access to the recep-
tacles for goods and the working parts. On the front of the case is a dial B, having
marked all round it the names of the various articles on sale, and lines radiate from
the centre of the dial to each name.
Under the name of each liquid is an opening with a little slide behind it, bearing
the words "full" and "empty "These slides are worked by suitably arranged floats
in the cisterns, to show the condition of the contents of each cistern."

page_text: In the dial is also a slit, for the reception of the coin or coins which form the price
of each article.
In the centre of the dial is a handle C and pointer D, both fixed to a shaft E, which
passes into the interior of the machine. When it is desired to obtain any article, the
handle is turned till the pointer lies over the radial line indicating the article required,
and on the necessary coin being passed through the slit, the handle can be pulled out,
and such pulling out actuates the internal mechanism to deliver the article, in a
manner to be presently described. On the front of the machine, at each side of the
dial, is a recess or cupboard F, containing a plated drinking cup H, attached by a
chain. These cupboards are fitted with glass doors F F', which close with a spring
and are released by means of any suitable device, through the action of the shaft E,
when delivering any liquid. Swing doors B¹ B₁ are also provided to shut up the dial
and cupboards at night or when the machine is not in use.
Below the dial is a row of taps J, each communicating with one of the cisterns,
except one tap, which may be connected to the neareast water main for supplying
water for rinsing the cups H or for a gratis supply. Below the taps is a basin K,
and at each side of the basin is a fixed slide L, on which solids are delivered.
The basin K swings on a hinge K', so that it can be turned up to enclose the taps,
it is provided with a ledge K2, which is shut in by the doors B₁ B', so that when they
are closed and locked, the basin is also secured.
cocoa,
The hot liquids supplied by the machine, as. here illustrated, are, tea, coffee, and
the cold liquids, iced filtered water, ginger beer and ordinary water; and the
solids are, biscuits of two kinds, sherbet, or other similar essence in cartridges, and a
fruit syrup, or other flavouring in small bottles, or tubes; but it is obvious that the
machine is not necessarily limited to either. the number or nature of the articles
enumerated, and in practice it will in may places be found advisable to substitute milk
for ginger beer.
Internally the case A is divided into compartments. The uppermost compartment M.
contains three cisterns NN1 N2, for the liquids which are intended to be kept hot, viz. :-
tea, coffee, and cocoa. The walls and floor of this compartment are lined with suitable
Underneath is
non-conducting material, and it extends from side to side of the case.
a smaller compartment P, also lined with non-conducting material and containing two
cisterns QQ, for the cold liquids viz.:-iced filtered water, and ginger beer.
The lower portion of the case contains two horizontal endless band carriers R, R,
and two coiled spiral carriers S, S, for solid goods; one horizontal and one spiral
carrier being placed on each side, as shewn. The goods from these carriers are delivered
on to the inclined slides L L. The carriers are filled with goods from the side, through
the doors A2 A3, in the sides of the case.
The cisterns for the liquids are preferably made of copper and tinned inside. They
have a well a at the bottom in which lies a measuring apparatus. The cisterns N N¹ N'
are each heated by small Bunsen Gas burners b, placed under them, but where gas is
not obtainable, suitable lamps may be employed. Each cistern is provided with a
float c, which is restrained from rising to the surface by a cradle c¹, and is placed
behind the measuring apparatus, and over the well a, into which it descends as the
liquid is drawn off, and its under surface being shaped to fit the well, it displaces
almost all the liquid and so enables the cistern to be practically emptied. This float is
free to rise and fall, only two or three inches, and consequently does not come into
action until the liquid in the cistern has fallen within a fixed distance from the bottom.
In the cisterns N N'N' the float is connected by a wire d, to a rock lever e at the top
which
of the cistern, one arm of this lever is connected by a wire f to the shutter
exhibits "full" or empty" through its slot in the dial B. The connections are so
arranged that when the liquid is run down nearly to the bottom the shutter is drawn
up, and the word "empty" comes into view.
"
9,
Another arm on the shaft of the rock lever e, is so connected to the gas cock h,
that as the liquid diminishes in level below the arranged point, the flame is gradually
lowerd and finally extinguished.
In the cisterns Q Q', which are both shewn as hermetically closed, a somewhat

page_text: different arrangement has, in consequence, to be adopted. In their case the float c is
connected to a lever e', which passes through a rubber diaphragm e², fixed over an
opening in the front of the cistern. The lever is fixed in the diaphragm, which
forms the fulcrum, by nuts and washers. The outer end of the lever is connected
by a wire to a shutter g, which it operates as in the case of the hot cisterns.
A screw-plug is provided at the bottom of the back of each well a for drawing off
the contents, when necessary.
The form of cistern bottom shewn in Fig. 2, with a well descending below a flat
surface is adopted for the purpose of enabling the contents to be almost entirely drawn
off and sold, as the measuring vessell and the float, when it descends, between
them nearly fill the well, and also in the case of the hot cisterns for enabling heat
to be applied under the flat surface where it can act to the best advantage..
Hermetically closed cisterns are only required for effervescent liquids, such as
ginger-beer, and the cisterns QQ¹ may be similar to the cisterns N 'N' N' if
desired.
The floor of the hot compartment M is made of wood, about of an inch thick,
and coated with a layer of asbestos, covered by tin plate, or zinc. The floor of the
cold compartment P is also of wood, and is provided with a zinc or leaden tray 1, to
hold water for the purposes of producing evaporation, and to catch the drip from ice,
when used in hot weather. This compartment is lined with non-conducting material
and is provided with an overflow connected to the waste pipe m from the basin K.
When ice is not employed the cisterns QQ¹ may be surrounded by fibrous cloths,
dipping into the water in the tray 1, the constant evaporation from which chills the
contents of the cistern in a manner well understood. The heated air from the upper
compartment M escapes through the tubular knob n on the top of the case, while fresh
air is drawn in at openings around the bottom of the case (not shewn in the drawings),
thus a current of air is established which promotes evaporation from the wet coverings
of the cisterns Q Q¹ and supplies air to the burners b.
On the shaft E behind the dial B is fixed a circular hollow casting p, having
three surfaces, viz. a flat annular disc g, a short cylinder and a short portion of a
cones; with this casting a detent t engages, which, when in place, presses upwards
against the cylindrical part of the casting, and in front of the flat end u of the cone s,
and so prevents the handle C, being drawn forward, but when the detent is drawn
downwards a certain distance, by the weight of coin acting on the coin lever, it
permits the handle C, shaft E, and casting p to be drawn forward. In one side of
the casting p, is fixed a radial bar or finger v which is so placed in relation to the
pointer D on the dial, that when the said pointer is on the line leading to the
name of any article, the bar is directly over the end of a lever, which when
depressed by it, effects a delivery of the said article. The shaft E is journalled
in a bush win a cast iron plate x, which carries the delivering lovers, and
which is attached to the inside of the front of the case A, immediately behind the
dial B. The inner end of the shaft E is supported by passing through a bearing
on a cross-bar 51. A circular guard-ring y is cast on the plate x, concentric
with the shaft E, its diameter, in the machine illustrated, is 10 inches. The object of
this guard-ring is to prevent the handle C being pulled out, except when the finger v,
which is long enough to reach the ring, is over the end of one of the levers before
mentioned and it can then only be brought fully forward when the dentent has
been withdrawn by the action of a coin. The said levers, marked z, work on fulcrums,
fixed on the plate round the shaft E, and their inner ends travel within slots in the
guard-ring y.
The detent t is a small vertical steel bar with a head shaped as shewn in Fig. 7,
working freely in a bracket 2. and steadied by a guide 2ª fixed to the guard-ring, and
it is attached by a stiff wire 3 and hinged joint, to the lever 4 underneath, on which
the coin acts.
The lever 4 works on a fulcrum 8 and is so balanced by the weight 7 that until the
proper coin or coins are inserted, the detent is kept pressed upwards against the
cylindrical part r of the casting p. The handle C can then only be drawn out a short

page_text: distance, as the step u from the cylindrical part to the conical part s abutting against
the detent, stops further movement. The coin is not delivered directly on to the
lever 4, but rests on a pin 9, fixed in and standing out horizontally at right angles
from it. This pin projects through a slot 10 in the coin shoot 11. A part of the shoot
runs nearly horizontally for a certain distance, immediately above the lever, in order
to direct the descending coin against the bend of the shoot and so exhaust its
momentum and cause the lever to be actuated by its weight alone. When the proper
coin, say one penny or two half-pennys, drop on the pin 9 on the lever 4 the said
lever descends carrying with it the detent t until it is stopped by the projecting.
head resting upon the rim q' on the disc q In this position the coin is still
retained in the shoot, but the detent has descended sufficiently to just clear the step u
aforesaid, so that the handle C can be pulled out. In pulling it out the rim qis
withdrawn from under the head t¹, and if from any cause, as for instance a .light
coin being received, the lever and detent do not descend sufficiently to discharge the
coin from the shoot, the cone s passing over the top of the detent depresses further
both it and the lever 4, sufficiently to ensure the coin being discharged from the
shoot 11, and dropping into the coin box 15. The lever 4 being thus released from
the weight of the coin, as soon as the handle goes back, raises the detent to its former
position, and locks the apparatus as before.
The coin lever 4 is necessarily so balanced by the weight 7 that if a coin
of two low a value is dropped in the shoot, it will not be heavy enough to
withdraw the detent.
.
When the handle C is pulled out the bar comes in contact with the end of one of
the levers 2, and delivers, either a portion of liquid or a solid article in the
following manner-Liquids are measured by an apparatus placed within the
well a of each cistern. This apparatus consists of a tube, preferably a copper
cylinder 20 of the required dimensions, having a valve at each end. The tube 20
is tinned, as also are other parts of the measuring apparatus exposed to the
action of the liquid. The outer valve is a rubber diaphragm 21, strengthened by
a metal ring 22 at the back round its edge, and rivetted through the rubber to
a narrower ring 23 on the front. This diaphragm is secured in the centre to the
rod 24 by nuts 25, 25, and washers 26, 26 and is kept against its seat by a spring 27.
When this valve is closed the inner valve normally stands open. This inner valve
consists of a metal disc 28, faced with rubber 29. It is free to slide on the rod 24
and is kept against a shoulder 30 thereon by the spring 31. It stands about an inch
The rod 24
off its seat, and thus permits the liquid to flow freely into the tube 20.
is coupled to one of the levers z, by a connecting rod 32. When the lever is depressed
by the bar v, the rod 24 is drawn forward. The first of an inch of this
movemement simply closes the inner valve 28 and prevents any more liquid flowing
into the tube 20. A further movement of of an inch takes place before the outer
valve 21 begins to open, when the shoulder 33 comes against the cross-head 34 and
draws it forward. This cross-head presses on the diaphragm 21 and pushes it open,
the thrust of the cross-head being borne by the metal ring 22, and through it by the
spring 27, which yields to the pressure. When the lever z is released, the spring 27
closes the valve; and the smaller interior spring 35 presses against the nut 25,
continues the, motion of the rod 24 and so again opens the inner valve 28, thus
permitting the tube 20 to refil. The measuring apparatus is held in place by being
screwed into a ring 20ª fixed in front of cistern, and projects forward into a metal
receptacle 37, fixed in place, to receive its contents, when discharged. This vessel is
large enough to hold two deliveries of the measuring vessel, and it is connected by a
pipe 38 with one of the spring taps J, by pressing on which the contents can be
drawn off into one of the cups H. A similar arrangement is applied to each cistern
and the chief object of placing the measuring vessel within the cistern, is, that the
contents may always be kept at the same temperature as the rest of the liquid
within the cistern, whether it be hot or cold.
The horizontal carriers for solid goods, each consist of an endless cord R, formed
preferably of links, as shewn, and carried on hexagonal rollers T, T¹; but rollers

page_text: with any other suitable number of faces can be employed, as required. A plate U
is affixed at right angles to each link, and the spaces between these plates form
compartiments, each containing one article. A fixed guide or plate V is provided to
prevent the articles falling out of the compartments, when on the underside and at
the back of the carrier.
A ratchet wheel W. Fig. 10 is fixed on the side of the roller T having the same
number of teeth as the roller has faces. A lover X, which is free to move on the
spindle of the roller T, is provided with a hinged pawl 39, and the upper end of
the lever is connected by a wire 40 with one of the aforesaid levers z, so that when the
lever is depressed, the pawl, which cannot move backwards by reason of the stop 39ª
on the lever, engaging with a tooth of the ratchet wheel moves the roller round one
face, in which position the plate U coming into an inclined position, the article Ub
slides off, falls down the shoot Va and out at the inclined slide L. The lever 39 is
returned to its normal position by a balance weight 41, or a suitable spring, which
also through the connecting wire, raises again the lever z. The spiral carriers cach
consist of a belt F of leather, or other suitable flexible material, having plates U
attached on one side, the spaces between these plates forming compartments each
containing one article. The centre of the spiral is formed by a snail-shaped piece 42
to which the inner end of the belt is attached, and then wound round, the other end
of the belt passes over a hexagonal roller T provided with a ratchet and pawl
arrangement, similar to that used on the horizontal carrier. In order to ensure the
belt being drawn forward the correct amount at each movement of the ratchet wheel,
the roller T is provided on each side with a plate 43 having six notches cut around it.
The plates U, as shewn more clearly in elevation in Fig. 11, are each provided
with a pin 44 the ends of which drop into the notches in the piates 43.
This arrangement would also be available for the horizontal carriers R if a flexible
belt were used instead of a linked belt.
The under-side of the spiral rests upon a curved plate 45, provided with
rollers 46, 47, to reduce friction. The bearings 48 of the spindle of the snail-piece 42
travel in vertical slots in the standards 49, so that as the spiral is unwound, it descends
and always rests upon the plate 45, as otherwise it would become necessary to
employ a resistance to keep the band drawn taut, as for instance a weight wound
up by a cord on the spindle of the snail-piece. A sufficient amount of plain belt
is wound round the snail piece as shewn at S₁ to ensure the last compartment
being able to reach the roller T, and be emptied. Each plate U on the spiral
carrier, as shewn in Fig. 11, has its centre cut out. The object of this is to
permit it to pass over the end of the delivering slide L (which is sufficiently
reduced in width for such purpose) and so to deliver the article it was carrying,
upon the said slide.
This arrangement may with advantage be also applied in many cases to the
horizontal carriers R.
A helical spring 50 surrounds the shaft E and abuts against the back of the plate a,
and the casting p, for the purpose of returning the shaft to its normal position, after
it has been drawn forward to effect delivery of any goods.
It will be obvious that many mondifications and additions may be made in connection
with the various parts of the apparatus, as described, without departing from the
essential principles of the invention, thus for instance, I have described a machine
in which the delivering levers are grouped in a complete circle, and the pointer
can freely revolve, but it is obvious that a portion of a circle may be used instead
of the whole.
Again the carriers R, for containing solids, which I have shewn placed horizontally,
may be arranged at an angle, or vertically, a similar construction and mode of
feeding the goods to the delivering slide being retained, but it will not work so
satisfactorily as in the horizontal position. Also arrangements for indicating numbers,
ringing a bell and closing the money slit, making visible the coin received, or of
counting the money taken, are easy to adopt if desirable, as there are many known
modes of doing these, which I may if required incorporate with the machine.
