5 Claims. (Cl. 312-36)
This invention relates to vending machines, and
with regard to certain more specific features, to
automatic bottle refrigerating and Vending
machines.
‘
Among the several objects of the invention
may be noted the provision oT a vending ma
chine of the class described, which is adapted to
handle bottled beverages and the like, for dis
pensing the same, which machine is equipped
10 with mechanism providing that the machine will
dispense a bottle only upon the presentation of
sponding parts throughout the several views of
the drawings.'
Referring now more particularly to Figures l,
2 and 3, numeral I indicates the casing or en
closure of the vending machine of the present Cl
invention. This casing or enclosure I is prefer
ably of a hollow-wall type of construction, as
indicated in Fig. 3, the >hollow portions of the
wall being filled with heat insulating material
such as that indicated at numeral 3, at least in 10
the upper regions of the casing; The casing I is
a coin of predetermined denomination thereto;
of a generally rectangular, box-likey construction,
the provision of a vending machine of the class
described in which the said mechanism is unusu
with the exception of a sloping face 5 provided
15 ally /simple in _construction and operation, and
contains a minimum number of operating parts
that are likely to get out of order; the provision,
in a machine of the class described, of means
whereby the machine' will receive a coin» for a
20 dispensing operation only when a bottle is avail
across the front upper edge thereof. The sloping
face 5 receives and mounts a double window 1,' 15
made of glass or some similar transparent mate
rial, so that the interior of the casing may be
seen.
-
-
Internally, the casing I is divided into a rela
tively large upper compartment 9 and a smaller
able to bee-dispensed, and is in dispensing posi
tion; the provision, in a vending machine of the
class described of means whereby Anot more than
lower compartment II. A partition I3, which,
like the walls of the casing, is‘ preferably of vin
one bottle may be dispensed for any one coin
9 and II. vIt is not important that the walls of
the compartment II be of the heat insulating
construction, because all refrigerating is donein
the upper compartment 9.
Access to the upper compartment 9 is pro‘
25 presented; and the provision of a vending ma
chine of the class described which is relatively
simple and economical in construction and oper
ation. Other objects will be in part obvious and
in-part pointed out hereinafter.
The invention accordingly comprises the ele
30
ments and combinations of elements, features
of construction', and arrangements of parts which
will be exempliñed -in the structures hereinafter
sulated construction, separates the compartments `
vided by means of a horizontally hinged door I5 `
in the upper region of the back of the casing. 30
The door I5 is provided with a suitable handle
and locking mechanism I'I whereby a supplier
of the bottles to be vended can obtain access
described, and the scope of the'application of to the interior of said compartment 9. Ordinarily,
which lwill be indicated in the following claims. vthe back.of_ the compartment II is left open, as

vention.
Since the dispensed bottles are ordi
narily wet from the refrigerating medium in the
compartment 9, a pipe or tube 63 is preferably
connected to the lower end of the basket 59 and
brought back into the casing I at such a point Ul
,
In order to provide that the purchaser may
move a bottle from one of the receptacles 23 into
the inside top of chute 21, a manipulating device
that it delivers the collected drippings of ice wa- A
indicated generally by numeral 3| is provided.
ter to an unobjectionable location (see Fig. 1).
Extending upwardly from the upper edge of
The manipulating device 3| comprises a ball 33
that is received in a universally swivelling joint
35 in the top of casing I. Slidably extending
the tube 41 are a pair of ears 65 which serve to
mount a pin 61, the axis of which is at right 10
angles to the axis of the tube 41. Swinging on
the pin 61 is a trip member or gate 69, which
comprises a flat camming portion 1| that ex
tends through a slot 13 (see also Figures 5 and 6)
into the interior of tube 41, and a stop member 15
proper indicated by numeral 15 at its opposite
end. At a lower point on the tube 41, but still
within casing I, a pair of studs 11 mounted on
10 through the center of the ball 33 is a handle or
arm 31, the lower end of which carries a clamp
comprising a pair of spring-pressed fingers 39.
A purchaser need only stand outside of the box
I and manipulate the outer end of the handle 31
so as to bring the clamp 39 around the neck of a
bottle 25. The purchaser can observe his move
ments through the window 1.
He then pulls
the handle 31 upwardly through the ball 33,
diametrically opposite points of the outside of
tube 41 serve to pivotally mount the opposite 20
sides of a U-shaped yoke 19. Numeral 8| indi
cates a finger that projects downwardly from the
central portion of the yoke 19, through the slot
13, and into the interior of the tube 41. Extend
ing upwardly from the same portion of the yoke 25
swivels the ball through whatever angle is neces
20 sary, and deposits the bottle in the top of the
chute 21. It is then a simple matter for him to
disengage the clamps 39 from the neck of the
bottle, and release the handle 31 for a subsequent
dispensing operation.
~
If the purchaser then places his coin in the
coin control device 29, and manipulates it in a
manner hereinafter to be described, the bottle he
has selected will be released and slide outwardly
through the chute 21 to the portion thereof out
30 side the casing I, where the bottle is free to be
lifted by the purchaser. A convenient accessory
on the outside of the casing I comprises a bottle
cap remover 4|, which includes a catch-all 43 for
receiving the bottle caps removed.
In ordinary operation, after all of the com
35
partments 23, or any desired number thereof, are
ñlled with bottles 25, crushed ice or iced water
or some similar refrigerating medium is filled
into the compartment 9 until it establishes a
40 liquid level such as that indicated at numeral 45
25
in Fig. 3.
are a pair of ears 85, which serve to mount a pin
81 for manipulative purposes hereinafter to be
described.
Gravity normally holds the gate member 69
so that the camming portion 1| thereof extends -30
across a substantial portion of the passage
through tubes 41. Gravity likewise . normally
holds the finger 8| of member 19 in position
across the passage through tube 41. Both the
members 1| and 8| extend sufficiently far into 35
the tube 41 that it is impossible for a bottle 25
to slide down the tube 41 without pushing both
members 1| and 8| aside.
The coin controlled device 29 will readily be
recognized, from Figures 4, 5 and 6, as being, 40
basically, of the slide type. It comprises a track
The bottles 25 are thus all chilled, or
refrigerated, during the time that they await dis
pensing.
The constructions of the chute 21 and coin
45 control device 29, and the manner of their co
operation, are indicated in Figures 4 through 8,
inclusive, to which attention is now directed.
The chute 21 comprises a tubular section 41,
which is of sufficient internal diameter to freely
50 pass a bottle 25. The tube 21 is mounted in the
walls of the casing in a sloping manner, as in
dicated in Fig. 4, so that its inner end is sum
ciently higher than its outer end, that the force
of gravity always tends to make a bottle slide
55 down the chute to the outer end thereof. At its
upper end, the tubular portion 41 turns slightly
upwardly, as indicated at numeral 49, and a
portion of the tube, indicated at numeral 5|, is
removed, in order to provide room for "certain
60 operating mechanisms to be described. The up
per end of the section 49 is normally open, so
that it may receive the bottom of a bottle Ipre
sented to the chute.
,
y
`
Closing the lower end of the tube 41, at the
65 point that it emerges through the walls 3 of
casing I, is a closure 53 that is freely pivoted on
a pin 55 mounted in ears 51 extending upwardly
from the tube 41. Gravity normally holds the
closure 53 shut, but said closure is free to rotate
70 away from the end of tube 41 whenever a bottle
comes down the chute. Also attached to the
lower end of the tube 41 is a cradle or bottle
receiving device indicated generally by numeral
59. The lower end 6| of this cradle 59 is closed,
in order to check the advance of a bottle being
89 in which slides a bar 9|, the bar 9| being pro
vided with a handle 93 at its outer end. A spring
pressed finger 95 is mounted on ears 91 raised
from the track 89. The slide 93 contains a hole 45
of suitable diameter to receive the predetermined
denomination of coin. The coin is placed in the
hole flat-wise, in a manner such that it forms a
substantial continuation of the slide 9|. If a
coin is present in the slide 9| when the handle 50
93 is pushed inwardly, so as to make the slide 9|
slide inwardly in the track 89, the finger 95 slides
freely over the surface of the coin and move
ment of the slide member 93 is not impeded.
However, if no coin is present in the hole, as soon 55
as the hole reaches the finger 95, the finger 95
falls therein, and prevents further sliding move
ment of the slide 9| in the track 89.
Numeral 99 indicates an extension that is se
cured to the rear end of the slide 9| .
The exten
60
sion 99 has a downwardly turned end |9|, to
which is hooked one end of a tension spring |99.
The other end of the tension spring |99 is fas
tened to the wall 3 (see Fig. '1) the tension spring
|93 thus serving to tend to return the slide 9| 65
to its outwardly extended position after each
manipulation of the device.~
Secured to the underside of the slide 9| is a cam
plate indicated generally by numeral |95. At its
rearmost edge, the cam plate |95 has a notch |91, 70
which receives the portion 15 o1' swingable gate
59. An intermediate portion of the cam plate |95
is provided with a substantially horizontal notch
|99, while the forward portion of the cam plate
|95 is provided with a substantially vertical notch
3
2,112,448
I||. The bottom edge |I3 of the cam plate |05
ahead of the notch I I | is higher than the bottom
edge ||5 of said plate |05 ahead of the notch I Il,
for reasons hereinafter to be made clear.
A sheet metal cover ||1 (see Figures 4 and 8) "
v normally incloses all moving parts' of the mecha
aside the cover 53 and presenting itself to the
purchaser in the cradle or basket 59._ Fig. 6 indi
cates the position of the elements at this stage
of operation. It will now be seen that the purpose
of the notch |09 in the cam plate |05 is to receive
or pass the ’pin 61, s6 that said pin does not oiïer
nism inside the box, leaving, however, a suilicient _an obstruction to the rearward movement of the
opening over’the upper end of tube section 49 to
receive a bottle, in the manner indicated in Fig. 4.
10 'I'he cover ||1 is preferably mounted on angle
brackets or like members ||9 secured to the in
side wall of the casing.
.
y
' The operation of the coin controlled device is
such that it normally delivers, or drops the coin
whichhas been fed to it, in a regionintermediate
between the two walls of the casing, such region
being indicated in Fig. 4 by numeral |2|. The
region |2| is accordingly left hollow in the casing,
20 and a chute |23 (see also Fig. 8) is provided be
tween the walls leading from said region |2| to
the opening |25 of a coin-receiving -box |21.
Locking means is provided von the handle I1, in
order that the .door may be opened and accessl
25 t'o the box |21 may be had only by a duly author
`ized representative provided with a key.
The operation of the coin-controlled delivery
15
chute mechanism as thus described is as follows:
Figure 4 indicates the normal, or non-operating
It will be -seen
that the portion 15 of gate element 69 interlocks
30 position of all of the elements.
with the notch |01 in the rear end'of cam plate
|05 attached to coin slide 9|. 'I'his is true only
so long as no bottle is present in the upper end
ofthe chute 21. If a purchaser now places a coin
in the slide 9|, in an attempt to manipulate the
same, he will ñnd that the coin control mecha
nism 29 will not slide -backwardly, or receive his
coin, because of this engagement of the member
40 15- with the notch |01. This action prevents the
device from receiving a coin without at the same
time deliveringa bottle in exchange therefore,
in the manner hereinafter to bedescribed. In
this manner, receiving of coins by the device after
45 the supply of refrigerated bottles has been ex
hausted, is prevented.
'
It, however, the purchaser, by manipulating the
-handle 31 in the manner described, has placed a
bottle 25 in the upper end of the chute 21, then
50 this bottle will, under the force of gravity, slide
down the tubular portion 41 until its bottom abuts
the finger 8|. In so doing, it will push aside the
cam portion 1| of gate element 69, and the various
elements will then assume the position indicated
55
in Fig. 5.
`
V
By reference to Fig. 5. it will be seen that the
bottle 25 has pushed aside'the camming portion
1| of element 69, and in so doing has rotated said
element 69 on the pin 61 to withdraw the portion
60 15 from engagement with the notch |01. Gravity,
alone, however, will not push aside the finger 8|,
because the pin 81 on projecting ears `85 engages
the lower edge H9 of cam plate |05. However, if
the purchaser now places his coin in the slide 9|,
65 and provided the coin is of a suitable denomina
tion, the slide 9| can be pushed rearwardly in the
track '89, because the portion 15 no longer engages
the obstructing notch |01. _As the slide 9| pro
gresses rearwardly, it carries withit the camming
70 plate |05, and soon the pin~81 comes into juxta
position with notch ||| and is forced to slide up“
wardlyin said notchA |||, thus rotating the yoke
19 on studs 11 and pulling the finger 8| out of the
i -Way of the bottle 25. The bottle 25 is now free to
travel on in the tube 41, and it does so, pushing
slide 9|.
-
`
By reference to Fig. 6, it will be seen that a
second bottle cannot now be delivered to the open 10
inner end of the chute 21 for delivery, because
the extension 99 mounted on the slide 9| forms a
gate or bar across the opening of receiving end
49 of the chute 21. This position of the elements
makes it impossible, foi` example, for a purchaser 15
, to surreptitiously position a second bottle in the
chute for delivery merely upon the presentation
of one coin. On the contrary, it is necessary
that the slide 9| be released and permitted to
return to its Fig. 4, or extended position, before
another bottle can be placed in the chute 21. And
then, to secure delivery of the said second bottle,
it is necessary to go through the manipulation of
placing a second coin in the slide 9|, and to repeat
all of the operations hereinbefore described. 'I'he 25
dimensioning of the various parts of the apparatus
is' such that the finger, or gate 8| cannot be with
drawn from position until the said extended por
tion 99 of the slide 9| is in location to prevent the
30
insertion of a second bottle into the chute.
It will accordingly be seen that the broad func
_tion of the various devices heretofore described
'I'he pivoted gate member 69 is for
the purpose of preventing 4the operation of the
. is as follows:
coin control mechanism 29 until a bottle is in 35
position for delivery. If no bottle is available 'in
the cooling chamber 9 of the device, obviously,
then, the device will not receive any money. 'I'he
gate 8| prevents the delivery of a bottle in the
chute until the coin of the proper denomination
has been placed in the coin control mechanism
29, and said mechanism has been suitably actu
ated.. The extending portion 99 of the slide 9|
constitutes a second gate, which, by ‘the very
operation of releasing the ñrst gate 8|, locks the
chute 21 so that a second bottle cannot be deliv
ered until the entire sequence of operation has
been repeated.
e
'I'he chute 21„ is thus, in eifect, equipped with _
two gates, comprising the gate `8| and the ex
tension 99. At no time during -the operation of
the device' are both-of these gates open at the
same time. Normally, the gate 8| is closed and
the gate 99 is open. To deliver a bottle, the gâte
8| opens and the gate .99,c10ses.v And, further
more, manipulation of any of the moving parts
ofthe device is impossible until a bottle has been _l
positioned to be delivered, because of the 'action
of the device 69 in the manner heretofore de
scribed.
_
. It will be obvious that upon suitable changes
of size and proportion andl shape of the lvarious
parts, the dispensing mechanism herein de
scribed may be adapted-for the vending of arti 65
cles other` than bottles.
`
In view of the above, it will be seen that theL `
several'objects. of the invention are achieved and
other advantageous results attained.
