VENDING MACHINE WITH COUNTING MECHANISM
Abstract
A vending machine has a hollow base and a merchandise container
supported thereby. A coin-actuated mechanism is preferably mounted
on the front wall of the base and is arranged to operate a wheel
which dispenses merchandise. A counting mechanism is mounted in the
base and is operatively coupled to the dispensing wheel in such a
manner that the counting mechanism is visible through an opening in
the rear of the base. Thus, the counting mechanism does not
interfere with servicing of the coin-actuated mechanism and also is
visible without gaining access to the interior of the vending
machine.

Description
BACKGROUND OF THE INVENTION
This invention relates generally to vending machines, but
particularly to a coin-controlled machine for vending articles of
bulk merchandise such as candy, gum balls, nuts, encapsulated items
and the like.
Most bulk vending machines in use today have no means by which the
amount of money deposited is counted during day-to-day operation.
Instead, periodically the machine must be opened, and the money in
the cash box thereof removed and counted. The serviceman who counts
the money and collects it thus has an opportunity to report only a
portion of the total collections and keep the remainder for
himself. Without a metering device, there would be no way by which
to check to determine whether all proceeds of a given machine have
been reported.
While there have been some vending machines available which meter
and count deposited coins on a day-to-day basis, these machines
have not been entirely satisfactory, basically because the meter
can be read only by disassembling the vending machine to gain
access to the interior thereof. Of course, the cash box then
becomes accessible for misappropriation of receipts by dishonest
collection men. Although such an internal meter would disclose a
discrepancy between money actually deposited into the vending
machine and the money which was being reported, the dishonest
collection man could falsify the records to that machine
indefinitely, until such time as someone else examined the meter.
By that time, the dishonest collection man could have drawn off a
substantial portion of the gross receipts of the machine.
Because of the difficulties with theft, it has been common practice
to have all collection men bonded, a costly procedure. Also, it is
not unusual for large operators of bulk vending machines to recall
their collection men periodically for lie-detector tests to
determine whether they have been misappropriating from the machines
for which they are responsible. This also adds to the cost of
operating the vending machines.
Another shortcoming of those few vending machines presently on the
market incorporating some metering arrangement is that the meter is
connected directly to the coin-actuating mechanism. Thus, each time
the coin-actuating mechanism is operated to dispense a quantity of
merchandise, the meter or counter registers accordingly. However,
it has been found that the coin-actuating mechanism is the most
likely component of a vending machine to require repair or other
servicing. With the counter engaged directly to the coin-actuating
mechanism, they must first be disengaged in order to service the
coin-actuating mechanism.
SUMMARY OF THE INVENTION
It is therefore an important object of the present invention to
provide an improved bulk vending machine which has a counting
mechanism that can be examined without gaining access to the
interior of the machine.
Another object is to provide a counting mechanism for a bulk
vending machine wherein the meter or display is visible from the
rear so as to enable placement of two or more such machines in
side-by-side relationship.
Still another object is to provide a counting mechanism for a bulk
vending machine which is not coupled to the coin-actuating
mechanism therefor.
Yet another object is to provide bulk vending machines which are
much less susceptible to pilfering of money by those having access
to the machines.
A further object is to facilitate servicing of the coin-actuating
mechanism of a bulk vending machine incorporating a counting
mechanism.
A still further object is to decrease the costs of operating bulk
vending machines by lessening the number of men having to be bonded
or to take lie-detector tests.
A yet further object is to provide a bulk vending machine, the keys
to which may be given only to a certain man who would have to be
bonded, but who can service a great number of machines since no
counting is required, and enable other unbonded employees to
periodically examine and record the gross receipts as of that time
without gaining access to the interior of the machine.
Another object is to provide a counting mechanism which is
irreversible so as to preclude a dishonest collection man from
appropriating to his own use a portion of the receipts without
indicating such appropriation.
Still another object is to provide a vending machine which can
readily and inexpensively be modified to accommodate a counting
mechanism.
In summary, there is provided a vending machine comprising a hollow
base having a wall with an opening therein, a merchandise container
supported by the base and releasably secured thereto, coin-actuated
dispensing means operative when a coin is deposited therein to
cause merchandise to be dispensed from the container, and a
counting mechanism mounted in the base and including a numerical
display device and operating means therefor, the operating means
being coupled to the coin-actuated dispensing means and responsive
to operation thereof to cause a corresponding change in the number
displayed by the display device, the display device being mounted
in the base so as to be visible through the opening therein to
enable examination of the displayed number without gaining access
to the interior of the base.
In a preferred form of the invention, the coin-actuated dispensing
means includes a dispensing unit and a coin-actuating mechanism,
the operating means being coupled to the dispensing unit to enable
the coin-actuating mechanism to be removed for servicing without
affecting the intercoupling between the operating means and the
dispensing unit.
With the foregoing and other objects in view which will appear as
the description proceeds, the invention consists of certain novel
features of construction, arrangements, and a combination of parts
hereinafter fully described, illustrated in the accompanying
drawings, and particularly pointed out in the appended claims, it
being understood that various changes in the form, proportion,
size, and minor details of the structure may be made without
departing from the spirit or sacrificing any of the advantages of
the invention.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Turning now to the drawings, there is shown a vending machine 10
preferably of a type capable of dispensing bulk merchandise such as
candy, gum balls, and the like. The vending machine 10 includes a
rectangular base 20 defined by side walls 21 and 22 joined at the
rear ends thereof by a rear wall 23 having in the upper left-hand
corner thereof (when viewed from the rear) a rectangular opening
26. At the front edges of the side walls 21 and 22 is a front wall
27, the whole central portion of which is open at 27a. Adjacent to
the opening along one side thereof is a rearwardly-directed finger
defining a keeper 28 having a slot 29 therein. There is provided a
set of flanges 30 secured to the walls 21, 22, 23 and 27 of the
base 20, along the upper edges so as to define channels 31
extending around most of the upper portion of the base 20.
The base 20 also includes a bottom wall 32, the marginal portions
33 of which are inclined slightly upwardly and outwardly. Money
deposited into the vending machine 10 will drop down onto the
bottom wall 32 where it will be stored until it is collected. An
upstanding rod 34 has its lower end threaded into a boss 35 on the
bottom wall 32, a lock nut 36 being provided to secure the rod 34
in place. The upper end of the rod 34 is also threaded.
The vending machine 10 also comprises a container mount 40 which
has a square outline defined by four side walls 41. There is
provided a chute 42 including an annular side wall 43a and a bottom
wall 43, which bottom wall has therein an annular orifice 44. The
bottom wall 43 and the adjacent portion of the annular side wall
43a is cut out at 45. Another portion of the bottom wall 43 and the
adjacent portion of the side wall 43a is cut out at 46. In one form
of the invention, the cut outs 45 and 46 were angularly separated
by about 135.degree. . Disposed centrally in the bottom wall 43 is
an upstanding boss 47 having an opening therethrough for receiving
the rod 34. Positioned within the chute 42 and resting on the
bottom wall 43 thereof is a merchandise wheel 50 having a central
opening for receiving the boss 47 on the container mount 40. The
merchandise wheel 50 includes a set of three holes 51 equiangularly
spaced therearound. Each hole 51 has a diameter less than the
diameter of the orifice 44 of the container mount 40. There is
provided a set of teeth 52 located around the periphery of the
wheel 50, each tooth 52 having a pair of
substantially-vertically-arranged engagement surfaces 53 and 54.
When positioned on the bottom wall 43 of the container mount 40,
the merchandise wheel 50 is free to rotate about a substantial
vertical axis. When one of the holes 51 is aligned with the orifice
44, whatever merchandise is contained in the hole 51 will drop
through the orifice 44. Also positioned within the chute 42 is a
member 55 having a top wall 56 covering one half of the member 55.
A curtain 57, defined by a set of vertical springs 58, is arranged
vertically between the top wall 56 and engages the upper surface of
the merchandise wheel 50. The member 55 is so arranged that the
orifice 44 in the container mount 40 is vertically aligned with the
center of the top wall 56. The member 55 prevents merchandise from
passing directly through the merchandise wheel 50 in the chute 42,
but, instead, requires the wheel 50 to rotate until one hole 51 is
in registration with the orifice 44.
Secured to the container mount 40 is a transparent container 60
which is slightly trapezoidal in vertical cross section, with the
distance between the side walls being slightly less at the bottom
than at the top.
A lid 61 fits onto the top of the container 60, a lock 62 being
provided which has a threaded interior and is rotatable onto the
upper end of the upstanding rod 34 when a key 63 is inserted.
Insertion of the key into the lock 62 enables rotation of the lock
62 to disengage it from the rod 34, whereupon the lid 61 may be
removed. To gain access to the interior of the base 20 where the
cash is located, the container 60 and the container mount 40
therefor are removed as a unit.
Mounted in the base 20 is a chute 70 having its inlet 71
communicating with the orifice 44 on the container mount 40. The
outlet of the chute 70 terminates in a flap 72 which is hingedly
mounted adjacent its upper end. Thus, merchandise which drops
through a hole 51 in the merchandise wheel 50 and through the
orifice 44 of the container mount 40 will pass through the chute 70
and rest against the flap 72. The merchandise may then be removed
simply by opening the flap 72, to enable the merchandise to fall
out.
The vending machine 10 also comprises a coin-actuated mechanism 80
including a front plate 81 having adjacent its top a coin-receiving
recess 82. A handle 83 is carried by a shaft 84, which shaft passes
through an outwardly-directed boss 85 so as pivotally to mount the
handle 83. The mechanism 80 also includes a rear plate 86 which is
spaced from the front plate 81. There is provided a space between
the plates 81 and 86 adjacent the right-hand side thereof as viewed
in FIG. 1, which space receives therein the adjacent edge of the
front wall 27 that defines the opening 27a. The mechanism 80 may
then be pivoted rearwardly until it reaches the position shown in
FIG. 2, whereupon a latch 88 may be moved to its locking condition
by engaging the keeper 28. Further details of the coin-actuated
mechanism 80 are not believed necessary to understanding the
instant invention. Any suitable such mechanism is appropriate so
long as the handle 83 will rotate only upon insertion of a coin
into the coin-receiving recess 82. The mechanism may include other
features such as a slug-rejector portion.
Mounted on the inner end of the shaft 84 is a gear 89, which gear
89 meshes with the merchandise wheel 50 through the cutout 45. The
shaft 84 is rotatable only in the clockwise direction, whereby the
teeth of the gear 89 will engage the engagement surfaces 54 of the
teeth 52. It should be noted that the merchandise wheel 50 and the
gear 89 are so constructed that the teeth of the two will
intermesh, despite the fact that the axes of rotation of the two
gears are normal to each other. Money deposited in the recess 82
passes through the coin-actuating mechanism 80, during which time
it is examined for proper denomination and whether or not it is a
slug. If the coin is in order, it will enable clockwise rotation of
the handle 83 to permit merchandise in one of the holes 51 to pass
through the orifice 44 and down the chute 70.
The vending machine 10 finally comprises a counting mechanism 100,
which counting mechanism includes a bracket 101 having three
flanges 102, 103, and 104, all arranged perpendicular to one
another. The flange 102 is secured to the rear portion of the side
wall 22 as by welding, so that the flange 103 is disposed generally
parallel to the rear wall 23 and spaced forwardly therefrom. Also,
the flange 104 will be arranged horizontally. A counter 105 has a
pair of outwardly-directed flanges 106 secured to the flange 103,
and fits within the space between the flange 103 and the rear wall
23. The counter 105 has a transparent plate 108 which protrudes
into the opening 26 in the rear wall 23 in such a manner that the
outer face of the transparent plate 108 is flush with the outer
surface of the rear wall 23. The digits 109 displayed by the
counter 105 can be viewed through the transparent plate 108. The
counter 105 includes a shaft 110 extending generally upwardly and
carrying a laterally-directed, plate-like lever 111 secured to the
shaft 110 by a set screw 112. There is also provided a shoulder
screw 113, having an enlarged head 114 and a threaded opposite end
115. The portion between the head 114 and the threaded end 115 is
unthreaded and rotatably receives a bushing 116. A gear 117 is
supported by the bushing 116 and includes a depending pin 118,
which gear 117 is secured to the screw 113 by a nut 119. The teeth
on the gear 117 engage the teeth 52 on the merchandise wheel 50
through the cutout 46.
As the gear 117 rotates, the pin 118 thereon engages a side of the
lever 111 to swing or pivot the same about an axis defined by the
shaft 110. MOvement of the lever 111 causes the counter 105 to
register and change the number represented by the digits 109. Each
revolution of the gear 117 will increase the number represented by
the digits 109 by one. Thus, each time the handle 83 is rotated an
entire revolution, to rotate the gear 89, the merchandise wheel 50
will rotate to dispense the merchandise contained therein, which
rotation of the merchandise wheel will cause a revolution of the
gear 117 and cause such revolution to register in the counter
105.
It is preferable that the number of teeth in the gears 89 and 117
are the same, so that one revolution of the handle 83 will cause an
entire revolution of the gear 117. Also, by using the same gear,
the expense of an additional part by virtue of the addition of the
counting mechanism 100 is reduced, since that particular gear is
already stocked. It should be noted that the teeth of the gear 117
engages the surfaces 53 of the teeth 52, which are the surfaces
opposite to those engaged by the gear 89. Also, the axis of the
gear 117 is parallel to the axis of rotation of the merchandise
wheel 50. Thus, the wheel 50 is so constructed as to enable
engagement by the gears 89 and 117 which have their axes arranged
normal to each other.
It is also noteworthy that the counter 105 is visible from the rear
of the vending machine 10, so as not to affect adversely the
appearance of the machine 10 when viewed from the front. Also, the
fact that the counter 105 is visible from the rear renders it
possible for a number of vending machines 10 to be arranged in
side-by-side relationship without obstructing the view of the
counters. Also, the counter 105 may be examined without having to
gain access to the interior of the vending machine 10. Thus, one
who periodically notes the reading on the counter 105 and examines
it can do so from the outside and need not have a key by which to
gain access to the vending machine 10 and the money contained
therein.
The counting mechanism 100 does not interfere at all with the
coin-actuated mechanism 80. During the course of operation of the
vending machine 10, it has been found that the coin-actuated
mechanism 80 often requires servicing either to repair it or to
remove a slug which has not been discharged. The coin-actuated
mechanism 80 may be removed by simply unlatching the latch 88 and
pivoting the same outwardly as shown in FIG. 3. The counting
mechanism 100 is not engaged directly to said coin-actuated
mechanism 80 and therefore need not be disengaged. Thus, the
advantage in operatively coupling the coin actuating mechanism 80
and the counting mechanism 100 individually to the merchandise
wheel 50 should be apparent.
The counting mechanism 100 can easily be installed on existing
vending machines, by merely mounting the mechanism as shown and
forming the cutout 46 in the chute 42.
In one form of the invention, the gears 89 and 117 were identical,
each having 10 teeth, except that the gear 117 had a depending pin
118. The merchandise wheel 50 had thirty teeth 52, so that one
rotation of the handle 83, caused the merchandise wheel 50 to
traverse one-third of a revolution and the gear 117 to traverse one
entire revolution.
It is believed that the invention, its mode of construction and
assembly, and many of its advantages should be readily understood
from the foregoing without further description, and it should also
be understood that, while the preferred embodiment of the invention
has been shown and described for illustrative purposes, the
structural details are, nevertheless, capable of wide variation
within the purview of the invention, as defined in the appended
claims.
