5 Claims.
This invention relates to vending machines and
particularly to machines for. vending cartons of
ice cream or the like from a refrigerated cham
ber 01' magazine constituting a part of the ma
chine.
An object of the invention is to provide a vend
ing machine for goods of the aforesaid character
which is simple in construction and operation,
and more particularly to provide new and im
proved means for transferring the goods from
the magazine to the delivery aperture of the ma
chine.
The invention provides a lifting device for car
tons or the like stored in the magazine, the lifting
11s device being operated by a winch which is actu
ated to cause the lifting device to raise a carton
a
out of the magazine, the carton being subsequent
ly released in position to pass to the delivery aper
ture of the machine and the winch drum being
freed to enable the lifting device to return to its
initial position.
One particular embodiment of the invention
will now be described, by way of example, with
‘ reference to the accompanying drawings where
25
Fig. l is a broken front elevation of a machine
for vending cartons of ice cream incorporating
the features of my invention;
Fig. 2 is a side elevation of the machine shown
3.0. in Fig. 1; and
Fig; 3 is a plan view thereof.
The machine illustrated in the drawings is of
duplex construction, having two lifting devices I
and two winches 2 operated from a single elec
35 tric motor 3 to deliver the cartons 4 from two
refrigerated chambers'or magazines 5. The elec
tric motor 3 which operates the machine is se
cured to a platform 6 carried by vertical guides ‘I
for the lifting devices and is ?tted with a re
duction gear 8 driving a shaft 9 to which a pin
,ion I0 is keyed.
pivoted levers I8 which normally fall inwardly
about their pivots from a vertical position to
within 30° of the‘ horizontal. On the top of each
hoist I and facing inwardly is a projecting arm
l9 which operates the striker 283 to be described. 5
A mechanism constituting a driving gear lock
designated generally by the reference 25 is
mounted on a fixed member 26 between the two
inside hoist guides l and comprises a central boss
21 mounted on .a pivot pin 28. Secured tov the
boss 21 are two horizontal arms 29 and a vertical
arm 38. The latter is crank shaped as shown ‘in
Fig. 2 and engages in a recess in the bottom of
the bracket H. A latch 3| for the driving gear
lock 25 is suspended from a bracket 32, mounted 15
on the fixed member 2%, as shown in Fig. 2, and a
lock lever 33 on the back thereof has a pin and
slot coupling with a fork 34. The latter is con
nected through a connecting rod 35 with a lower
fork 36 which engages in the striker 20.
The striker 2Q comprises two discs 38 and 39
each having a gap til cut in its periphery and a
radial slot 4! formed diametrically opposite the
said gap.
The discs 38. and 39 are mounted on
shafts ‘l2 and a cross pin £33 carried by the col 25.
lateral parts of the lower fork 36 engages in the
radial slots M of the discs as shown in Fig. 1.
A tension spring 4G is located between a pin 45
projecting outwardly from the disc 39 and the
shaft 42 of the other disc 36 whereby a snap action 30
past the centres is obtained.
The ice cream cartons 4 are contained in re
frigerated chambers 5 in a magazine of the form
shown in dotted lines in Fig. 2 whereby when
they are fed in from the top they roll down to 35
the mouth of the magazine ready to be picked up
by the respective hoist l. Bell crank levers 48
constitute coin mechanism trips, one end of each
lever projecting over the respective hoist I as
shown in Fig. l. and the other end being attached
This shaft also has swivelly
to a latch on the coin mechanism switch (not
mounted thereon a bracket II carrying a second
shown).
A delivery chute 4.9 is provided to which the
cartons are guided by guide rods 5!], bent forward
ly at 5! to insure discharge thereof as they reach
Pthe mouth of the delivery chute. An “empty”
sign trip 52 may also be provided at the lower end
of the device in position to be engaged by the
hoist when the magazine is empty. This sign
trip is adapted by means (not shown) to cause an
“empty” sign to be displayed after the last carton
has been discharged.
The operation of the machine is as follows:
Assuming the machine is at rest with both
hoists I at the bottom of the guides l and resting
pinion I2 in mesh with the pinion ID. The
bracket H is loose to swing in either direction
45 with. the pinions I0 and I2 constantly in mesh.
Mounted on the platform 6 on opposite sides of
the pinions l0 and I2 are winches 2 the cables I3
of which are attached to the lifting devices or
hoists I. Each winch 2 has a gear I4 with which
50. the pinion I2 may be brought into mesh in a
manner hereinafter described.
Each hoist l consists of an inverted U-shaped
bracket. I5 the depending parts l6 of which have
55.
(Cl. 312——66)
projections [l which run in the vertical guides
1. On the inside of each depending part I6 are
2
2,121,457
on the lowermost carton as shown in Fig. 2, the
striker 20, gear lock 25 and lock latch 3| will be
in the positions shown in Figs. 1 and 2, the dis
position of the slots 4| in the striker discs 38 and
39 thereby throwing the forks 36 and 34 upwards
to free the lock latch 3| so that the arms are
free to move. With the various parts of the
mechanism in the aforesaid positions and the
driving gear in its neutral position a coin is in
10 serted in one of the coin slots and this moves
the motor switch to the “on” position, the switch
being held by the aforesaid switch latch. As soon
as the motor commences to turn the torque causes
the loose bracket II to swing over and the pin
15 ion l2 to engage with one or other of the gears
H on the respective winch 2 and to rotate the
same to raise the corresponding hoist I, the piv
oted levers l8 of which engage beneath and sup
port the carton to be delivered. The motor 3 is
so connected that it turns in either direction ac
cording to which switch is made, the respective
switches being made by the insertion of a coin
in the respective coin slots. According to which
direction the inserted coin has caused the motor
to turn, the bracket H swings over to one or
other side in Fig. 1 to mesh with the respective
gear Id. In addition to causing the pinion l2 to
mesh with one of the gears M, the movement of
the bracket II moves the vertical arm 30 of the
gear lock 25 engaged in the slot therein to tilt
it about the pivot 21. The horizontal arms 29
are thereby tilted correspondingly, the arm on
the same side as the hoist being operated moving
downwards as will be readily understood. The
35 projecting arm H) on the operative hoist, due to
the ascent of the latter, engages in the gap 40
of the respective disc 38 or 39 of the striker and
rotates the disc.
The slot M of the disc, mov
ing downwards, draws down the pin 43, lower
fork 36, connecting rod 35 and upper fork 34,
40 whereby the latch 3| is moved into position to
lock the arms 29 when they are again shifted to
horizontal position by the arm l9.
The continued ascent of the hoist I carries the
cartons to the mouth of the delivery chute 49
where it rolls off the levers I8. To insure the
correct delivery of the carton to the chute 49
should the carton be stuck in the hoist, guide
rods 50 are bent forward at 5|, as shown in
Fig. 2, whereby the carton is forced off the levers
l8 opposite the chute 49. Immediately after the
delivery of the carton to the chute 49, the pro
jecting arm l9 strikes the lowered arm 29 of the
gear lock and throws the driving pinion H into
neutral position, the latch 3| falls into position
due to the arms 29 having returned to a hori
zontal position and locks the gears in neutral
of the hoist in descending does not abut a carton
and consequently descends further than if a car
ton were present and contacts with an “empty"
sign trip 52. This lowers a plate over the re
spective coin slot and prevents any coins being
inserted until the magazine has been reloaded.
Although a particular embodiment of the in
vention has been shown for purposes of illustra 10
tion, it is to be understood that various changes
and modi?cations may be made therein as will
be apparent to a person skilled in the art. The
invention is only to be limited in accordance with
the following claims when interpreted in view of 15
the prior art.
The invention claimed is:
1. In a vending machine having a delivery
aperture and a storage magazine for cartons or
the like to be vended, a lifting device for said 20
cartons comprising a hoist having means to suc
cessively remove the cartons from said magazine
and to deliver the same to said delivery aper
ture, a winch connected to raise said lifting de
vice, a gear driving said winch, a motor-operated 25
driveshaft carrying a pivoted bracket, a pinion
mounted on said bracket and driven by said
shaft, said pinion being normally disengaged from
said gear and being shiftable into driving engage
ment with said gear by the torque produced by 30
rotation of said shaft, and means actuated by
said lifting device at the upper limit of its path
of travel to disengage said pinion from said gear
and to maintain said pinion in the disengaged
position, whereby the driving connection is broken 35
and the lifting device is permitted to return by
gravity to its initial position.
2. In a vending machine having a pair of de—
livery apertures and a pair of storage magazines
for cartons or the like to be vended, a lifting
device for successively removing cartons from
each of said magazines and delivering the same
to the respective delivery apertures, driving means
including a driven gear for each of said lifting
devices, a motor-operated driveshaft having a
bracket pivoted thereon, a pinion mounted on
said bracket and driven by said driveshaft, said
pinion being normally disengaged from said
driven gears and being adapted to be swung into
mesh with a selected gear by the torque produced 50
by the rotation of said driveshaft, means actuated
by said lifting device to return said pinion to
neutral position when said lifting device reaches
the upper limit of its path of travel, means look
ing said pinion in neutral position during the 55
as soon as they have passed, the ?nal position
descent of said lifting device, and means asso
ciated with said lifting device to release said
look when the lifting device reaches the lower
limit of its path of travel.
3. In a vending manhine having a pair of de 60
livery apertures and a pair of storage magazines
for cartons or the like to be vended, a lifting de
vice for successively removing cartons from each
of said magazines and delivering the same to the
respective delivery apertures, driving means in 65
cluding a driven gear for each of said lifting
devices, a motor-operated driveshaft having a
bracket pivoted thereon, a pinion mounted on said
bracket and driven by said driveshaft, said pinion
being normally disengaged from said driven gears 70
and being adapted to be swung into mesh with
one or the other of said gears depending upon the
direction of rotation of said driveshaft, means ac
tuated by said lifting device at the upper limit
of the parts of the hoist being as shown at the
of its path of travel to return the pinion into 76
position.
Simultaneously the hoist strikes the
horizontal arm of the bell crank lever 48 of the
coin mechanism trip to move the latch on the
60 coin mechanism switch to inoperative position
and the switch returns to the “off” position.
Meanwhile the next carton has rolled from the
mouth of the magazine into position to be picked
up by the hoist which descends by gravity; the
(35 projecting arm IS on the descending hoist en
gages the striker mechanism 20 to reverse the
operation previously described, thereby unlock
ing the gear lock 25 and leaving it ready for
the motor 3 to throw the pinion l2 into mesh
with one or other of the gears l4 when it is
again started. The pivoted levers N3 of the hoist
take up a vertical position as the latter comes
opposite the carton and then fall inwardly again
