Improvements in Coin-freed Apparatus for Delivering Goods.
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:
My invention relates to apparatus of the kind described in my previous Specification
No. 983 of 1888 whereby quantities of various solid or liquid goods are delivered on
introducing a coin and pulling a handle. According to my present invention, instead
of turning an index to a particular class of goods marked on a dial and then pulling
the axis which carries the index, I provide for each class of goods a separate knob or
pull, none of which can be pulled outwards unless a locking disc or ring has been
freed by the introduction of a coin, and this locking disc or ring is so arranged that,
when one is pulled out, all the other knobs or pulls are locked.
In case some of the
goods are to be delivered at different prices from the others, the locking disc or ring
or several of these are arranged with suitable stops or detents which are acted on to
a greater extent or in greater number acqording as a greater number of coins is
introduced.
For delivering a quantity of liquid, I employ, as before, a measuring vessel
situated in the bottom of the reservoir of cach liquid, and T provide this vessel with
two valves, the one a slide valve which, on their common stem being pulled, is first
moved io cover lateral holes that admit the liquid to the vessel, and the other a shut-
off valve which is afterward opened to allow the contents of the vessel to run out.
When the liquid reservoir is heated by gas flames I provide for shutting off the gas,
when the reservoir becomes nearly empty, by balancing the reservoir by a weight or
spring so adjusted that when the reservoir becomes lightened by the emptying of its
contents. it rises and thereby acts on a cock or valve governing the gas supply so as
to reduce or extinguish the fame.
For delivering paper cups or other similar round articles, I arrange a number of
these on a travelling chain each article held on one of the links by a spring clip. As
each link is brought in succession over the upper of two chain wheels, a fixed inclined
arm passing under the article on the link releases it from the clip and thereupon it
rolls or slides down the incline to a delivery mouth. When the articles are piled one
above another in a vertical case, supported by a moveable bottom which, as each
article is removed in succession from the top of the pile. is caused to ascend by a
balance weight, the load to he lifted varies very much from the maximum, when
the case is full, to the minimum, when it is all but emptied. In order to avoid the
use of a balance weight so heavy as is necessary for the maximum load, I provide in
each case, in addition to a moderate 'weight, a helical spring under the moveable
bottom, which spring is most compressed and therefore exerts most ascensional force
when the case is full, and becomes gradually weaker as the load above it becomes
lessened.

Improvements in Coin-freed Apparatus for Delivering Goods.
1, 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:
-
My Invention relates to apparatus of the kind described in my previous
Specification No. 983 of 1888 whereby quantities of various solid or liquid goods
are delivered on introducing a coin and pulling a handle. According to my present
Invention, instead of turning an index to a particular class of goods marked on a
dial and then pulling the axis which carries the index, I provide for each class of
goods a separate knob or pull none of which can be pulled outwards unless a locking
dise or ring has been freed by the introduction of a coin and the knobs or pulls are
so arranged that, when one is pulled out, all the other knobs or pulls are locked. In
case some of the goods are to be delivered at different prices from the others, the
locking disc or ring is arranged with suitable stops or defents which are acted on to
a greater extent according as a greater number of coins is introduced.
For delivering a quantity of liquid.
situated in the bottom of the reservoir of each liquid, and I provide this vessel with
employ, as before, a measuring vessel
two valves, the one a slide valve which, on their common stem being pulled, is first
moved to cover lateral holes that admit the liquid to the vessel and the other a shut
off valve which is afterward opened to allow the contents of the vessel to run out.
When the liquid reservoir is heated by gas flames I provide for shutting off the gas
when the reservoir becomes nearly empty, by balancing the reservoir by a weight or
spring so adjusted that when the reservoir becomes lightened by the emptying of its
contents, it rises and thereby acts on a cock or valve governing the gas supply so as
to reduce or extinguish the flame.
For delivering paper cups or other similar round articles T arrange a number of
these on a travelling chain each article held on one of the links by a spring clip. As
each link is brought in succession over the upper of two chain wheels. a fixed
inclined arm passing under the article on the link releases it from the clip and there-
upon it rolls or slides down the incline to a delivery mouth. When the articles are
piled one above another in a vertical case supported by a moveable bottom which, as
cach article is removed in succession from the top of the pile, is caused to ascend by a
balance weight, the load to be lifted varies very much from the maximum, when the
case is full to the minimum, when it is all but emptied. In order to avoid the use of
a balance weight so heavy as is necessary for the maximum load. I provide in each
case, in addition to a moderate weight, a helical spring under the moveable bottom
which spring is most compressed and therefore exerts most ascensional force
when the case is full, and becomes gradually weaker as the load above it becomes
lessened.

apparatus embodying my improvements. The dial A has around it a number of knobs

by introduction of a coin or coins to release any of the pulls B. which with their stems
are shewn in elevation by Figures 4 and 5, and Figure 6 shews the chain arranged

is a stationary ring fixed by stud bolts to a plate secured to the front of the
casing A. On a spindle K is mounted a thin ring K which has notches & cut in its
circumference, one for each pull B. As shown by Figures 4 and 5, the stem of each
pull B has on it a projecting feather 131 part parallel to the axis and part sloping.
There is also through each stem a hole 12 into which enters the end of one of the
levers L. From the ring K extends a lever M having at its end a pin m which
projects through a slot of the coin shoot C¹. When a coin descends the shoot C¹ and
incets the pin m it causes the lever M to descend until it rests upon a balanced
arm N.
In this position of the lever M all the notches of the ring K which are
intended to permit of the delivery of the cheapest articles are brought to face the
feathers B and thereupon any one of the knobs B which are thus liberated, can
he pulled, operating the corresponding lever L. By the pull of the knob B the
sloping part of the feather B' in passing along the notch & causes the ring K to
turn farther round depressing the lever M and its pin m below the shoot C' so as to
discharge the coin which descends a shoot. C² into the coin receptacle below. The
feather B is formed with a shoulder B³ so that if the knob be pushed back after
discharge of the coin it cannot be pulled out again because the notch of the ring K
will have been brought in front of the shoulder B by the action of the counter-
weight K². In some cases several coins have to be introduced before releasing some
of the knobs B. I provide for this by making some of the notches & farther from
the position of some of the feathers B and by duplicating as shewn in Figures 2
and 3, or by triplicating, as the case may be, the counterweighted lever N so that
iwo or three coins instead of one have to push down successively the arms N before
the ring K is brought sufficiently far round to release some of the knobs B. The
slope of the feather B is shewn in Figure 4 which is suited for two coins as being
less rapid than in Figure 5 which is suited for one coin, because when two coins
have been introduced, the stroke to be given to the lever M in order to discharge
them is less than when only one coin is introduced, the lever having already been
brought lower by the two coins than it would have been by one coin. When one
knob B is pulled any other of the knobs is prevented from being pulled by a ring
chain B (Figure 6) which is passed round the ring through loop attached
to each of the levers L and a pair of loops J. one on each side of L' attached
to J. The chain is sufficiently slack to permit one lever to be pulled but no more.
Figure 7 is a longitudinal section and Figure 8 is a transverse section on X of the
measuring vessel for delivery of liquids such as tea or coffee. This vessel 0 is cylin-
drical fitted with a piston O' packed but not so tightly as absolutely to prevent
leakage past it. In the front part of the vessel is a valve consisting of a flexible
diaphragm 0 secured at its edge by a ring on which abuts a spring (2. The
diaphragm is fixed at its centre to the rod 0 which is free to move a certain distance
through a case or crosshead 05. When the parts are in the position shewn in Figure 7
a portion of the liquid in the cistern entering the vessel 0 by slots o charges it. On
now pulling forward the piston by one of the levers L acting in the notch 0% ai
the end of the rod, the piston, by the first part of its movement, closes the slots o and
when the shoulder on the rod (4 bears against O, the valve 02 is opened allowing the
whole of the contents of 0 to flow out at o¹. Figure 9 is a longitudinal section and
Figures 10 and 11 are transverse sections on X and Y, of a measuring vessel suited
for small quantities of viscid liquids, such as fruit syrups. In this case there are two
pistons urged back and kept apart by springs. On pulling the rod O the piston (¹
first closes the supply slots and then the piston Of is advanced, past the discharge
slot o and the piston 0 overtakes 0 discharging the liquid contained between
the two pistons. The spring 0 aids the advance of 0 and thus lessens the fluid
pressure between the two pistons. Figure 12 is an end view and Figure 13 is a side
view of one of the cisterns heated by gas jets P. Under one end of the cistern is
a spring P which when the cistern is nearly empty raises that end of the cistern and
as the liquid is thus displaced the spring still rising acts on the lever P2 of the gas
cock reducing or cutting off the supply of gas. Figure 14 is a side view and Figure 15

chain Q has projecting from it a number of spring clips Q' each embracing one of
the cups.
The upper chain wheel is moved step by step by means of a ratchet and
pawl worked by a pull Q from one of the levers L. Each cup as it is brought
to the position Q meets a pair of inclined arms Q which release it from the clip
in which it is held and, allow it to run down the curved shoot Q to the delivery
mouth F (Figure 1). Figures 16 and 17 are vertical sections shewing the case for
delivery of cakes, small packets and the like. Figure 16 shewing the case full and
Figure 17 shewing it about half emptied. Figure 18 is a back view, and Figure 19
is a vertical section drawn to an enlarged scale of the upper part of a case con-
taining biscuits. Under the pile of packets I place a spring which acts in aid
of the counterweight R' until the case is about half empty, thus rendering unnecessary
a counterweight so great as would be required to overbalance the whole weight of the
packets in the case when it is full.
As shewn in Figure 19, a pawl lever S worked from one of the levers L, in
making its forward stroke with its pawl S' sweeps off the uppermost article to the
shoot S² down which it slides to the delivery shelf G (Figure 1).

Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. The combination of a set of circularly arranged knobs or pulls and their feathered
stems with a notched ring caused to turn partly round by the weight of introduced
coins, substantially as and for the purposes herein set forth.
2. In combination with the pulls and notched ring above referred to, a balanced
arm or set of balanced arms carrying the coin or coins and so determining the
position of the ring until the movement of the ring effected by the sloped feather
of the pull causes the coin or coins to be discharged substantially as described.
3. The construction of the measuring vessel with piston and valve herein described
with reference to Figures 7 and S.
4. The construction of the measuring vessel with two pistons herein described with
reference to Figures 9, 10 and 11.
5. Applying to the end of a cistern heated by gas a spring connected to the gas
cock so that on the contents of the cistern becoming considerably reduced the gas
supply is reduced or cut off, substantially as described with reference to Figures 12
and 18.
.
6. The apparatus described with reference to Figures 14 and 15 for the delivery of
paper cups or like articles.
7. In combination with a case containing packets or solid articles, a spring arranged
to act in aid of the counterweight, and the pawl for delivering the uppermost article,
as herein described with reference to Figures 16 to 19 inclusive.
