Application January 11, 1937, Serial No. 119,902
15 Claims.
This invention relates to can ?lling machines,
my principal object being to- provide a machine
for‘ the purpose by means of which measured
quantities of produce of di?erent kinds (such as
5.‘ different fruits to form fruit cocktail) may be
transferred from a hopper unit into cans without
any manual attention being necessary other than
keeping the hoppers ?lled. By means of this
machine all the cans are ?lled to the same extent
and all contain the same percentages of different
ingredients. While the machine is particularly
designed to thus supply different ingredients to
the cans, it can be used, if desired, and without
change to ?ll cans with one ingredient only.
Another object is to provide an automatically
functioning device to tamp certain kinds of pro
duce into the receptacles of the machine as said
receptacles pass under the hopper. This feature
is of particular use in connection with sliced
2o ‘peaches and the like which have a tendency to
(01. 226—100)
straight, form a continuous unbroken surface.
The boards are relatively short so that they can
pass about the sprocket wheels without forming
unyielding straight surfaces of any great length.
The wheels 3 are driven at a. slow speed by any
suitable means in such a direction that the upper
runs of the chains move upwardly or in the direc
tion of the wheels 3.
The boards along the upper run of the chains
form the bottom of a produce hopper 6 which 10
is divided by a transverse partition '1 into a pair
of compartments 8 and 9, the compartment 8
being relatively small and being at the low or
initial end of the hopper.

Secured in and projecting at right angles from
the outer faces of alternate boards are cylindrical
receptacles H], the bottoms of which are formed
by plungers, and which have the same capacity
as the cans into which the contents of the recep- '
tacles are to be discharged. Each plunger is. 20

specification and claims.
In the drawings similar characters of reference
indicate corresponding parts in the several views:

partly in section.

Figure 3 is a fragmentary transverse section
on the line 3—3 of Fig. 2.

'
Figure 4 is a similar view showing‘ a modi?ed
form of hopper‘ and metering device.
Referring now more particularly to the char
acters of reference on the drawings, the machine
comprises a suitable frame I on which are mount
45 ed transversely spaced pairs of longitudinally
spaced sprocket wheels 2 and 3. These wheels
are of different sizes, the wheels 3 being consider
ably greater in size and disposed relative to the
l
DC
wheels 2 so that their lower edges lie in a common
horizontal plane as shown; the upper edges of
. the wheels 3 being thus correspondingly higher
than the upper edges of the wheels 2.
Taut chains 4 pass about the sprocket wheels
and support boards or plates 5 which extend
55 therebetween and which, when the chains are
tracks are arranged so that the plungers are at
the bottom of the receptacles as the latter pass
under the hopper and are at the outer ends of
the said receptacles when the latter are inverted
and pass along the lower horizontal run of the
chains. Said run of the chains is above and par—
allel to a conventional can conveyor l6 moving
at the same speed as the chains and receptacles
and on which the cans ll are disposed; said cans
being spaced the same as the receptacles and
being disposed in registering relation therewith. - gs 0
Interposed in the hopper compartment 8, clos
ing the same just above the boards 5 is a rotary
metering device l8 having a series of circumfer
entially extending pockets E9, the width and
length of which at the periphery of said device 45
being no greater than the diameter of a recep
tacle ID. This device is disposed so that when
one pocket is open to and receiving from the
hopper compartment, another one is discharging
into» a receptacle. The device is intermittently
rotated an arcuate amount equal to the distance
between adjacent pockets in timed relation to
the movement of the receptacles by 2. spoke mem
ber 21] connected to the axial shaft 2! of the
device outwardly of the hopper, said spokes being 55

successively engaged by pins 22 projecting at in
tervals from one of the chains.
The size of the pockets is such that each only
holds enough produce to partially ?ll a recep
tacle, the receptacles being subsequently ?lled to
capacity by the produce contained in the main
hopper compartment 9, which produce is freely
open to‘ the boards 5 and the receptacles depend
ing therefrom.
Due to the upward slope of the
10 bottom of the hopper (as formed by the boards 5)
the produce tends to remain at the lower end of
the hopper, so that the likelihood of any conges
tion of the produce at the upper end of the hop
per is avoided. However in order to prevent pos
15 sible excessive ?lling of the receptacles such as
would tend to cause a congestion of produce as
the receptacles pass under the upper end of the
hopper, I mount a transversely extending brush
23 in the hopper adjacent its upper end. This is
20 positioned to sweep across the top of the recep
tacles and dislodge any excess produce therefrom,
so that said receptacles pass from under the
hopper in a properly ?lled condition. To prevent
the produce spillingout from the receptacles as
25 the latter are moved about the sprocket wheels 3
to an inverted position, a guard plate
extends
from the hopper about and close to the boards 5
concentric with the wheels 3.
To lightly tamp down the produce dropping
30 into the receptacles from the main hopper com
partment 9 I provide a rotary device comprising
a plurality of spokes 25 radiating from a verti
cally movable transverse shaft 26 and having en~
larged rounded heads 21 adapted to enter the
35 receptacles for a certain portion of their depth.
The end portions of the shaft extend through
vertical slots S in supporting brackets B mount
ed at the sides of the hopper, so that the shaft
can move up and down acertain distance with
out restraint. These heads are arcuately spaced
the same as the spacing between the receptacles
and the device is rotated by the engagement of
said heads with successive receptacles. The
weight of the device (which may be added to by
any suitable means if necessary) is sufficient to
exert the desiredtamping pressure on the pro
duce in the receptacles, and if the produce is
sufficiently dense without tamping the shift lifts
of itself so that the heads do not enter the recep~
50 tacles to unduly compress the produce.
The metering device and hopper compartment
3 as shown in Fig. 3 is intended to meter only one
kind of produce.
If two metered ingredients in
small quantities are desired as is sometimes the
case, the compartment 8 is divided by a longitu
dinal partition 28 into a pair of transverse com
partments 8a, and the pockets of the metering
device I80. are each divided into a pair of smaller
transversely separated pockets Ilia as shown in
Fig. 4.
From the foregoing description it will be read
they have passed beyond the hopper; there being
means to support cans in position to directly re
ceive produce from the inverted receptacles.

therein as the latter move along the hopper; said
last named means comprising a turnable shaft 20
extending transversely of the row of receptacles
above the bottom of the hopper, elements radiat
ing from the shaft and depending into the hopper,
said elements‘ at their outer end being adapted
to enter the receptacles to a certain depth when 25

their outer ends being the same as that between
adjacent receptacles, and means mounting the
shaft for unrestrained upward movement from a 30
predetermined position.

under the hopper and tamp produce into the
receptacles as the latter thus move; said last
