present machine, and show how the objects of
The invention relates to a process for ?lling
cans and other containers and also to a can ?ll
ing machine of a type used to ?ll to a ?xed level
a can which has previously been packed with
5 fruit, berries, or vegetables, such as peas, peaches,
and strawberries.
Syrupers of known construction release a pre
determined volume of liquid into each can. Due
to the fact that the material packed in a can
10 is of various bulks, the space to be ?lled by the
liquid varies over a wide range. When a prede
termined volume of liquid is discharged into a
series of cans, some of the cans will not be ?lled
to the preferred height, while others will have
15 over?owed syrup wasted.

right brackets 4 fastened to standards I are con
nected by a bearing holding cross member 5.
A supply tank 6 is provided with a tubular
raised center 1, the latter being threaded at its 10
uppermost extremity. The tubular center 1
forms a sliding sleeve on a center rod 8 so that
the tank 6 may be raised or lowered by a hand
wheel 9 threaded on its inside. Said threaded
section engages the threaded tubular center 'I 15

machine which will fill cans without waste. An
other object of my invention is to provide a proc
25 ess for ?lling containers with liquid to a pre
determined height without over?owing such con~
Tank 6 is raised or lowered to ac
commodate different heights of containers which
passes therethrough with liquid to a pre-selected'
height. A further object of the invention is to

tremity of rod 8 is reduced in size so that a ?ange 20
in hand wheel 9 loosely ?ts on the shoulder pro
duced by such reduction. Thus, the hand wheel
9 is maintained at a ?xed height as is clearly
shown in Figure 2.

While the improvements herein described are
disclosed as being applied to a syruping machine

with a liquid, the device may be adapted to ?ll
containers‘, such as bottles, jars, or cans.
With these ends in view, the invention is illus
trated in the accompanying drawings in which:—
Figure 1 is a side elevation of the invention
shown in connection with a can ?lling machine.

Figure 5 is a fragmentary view, partly in'isec
' tion, of a container lifting piston.
Figure 6 is a diagrammatic view illustrative of
the principle and operation of the invention.
Figure 7 is an enlarged fragmentary sectional
view of the ?ller head disclosing the manner in
which air and surplus liquid are drawn off.‘
Like reference characters are used to designate
similar parts in the drawings and in the descrip
tion of the invention hereinafter given.
Reference should be had to the details in the
55 drawings which illustrate the construction of the
side of the tank.
A ?ller head I 0 consists of a
?anged section II substantially in cross-sectional
shape somewhat resembling an annular inverted 30
trough which is pressed tightly against the rim
or free upper edge of a container while the latter
is being ?lled. A right ?t of the ?anged portion
I I upon a container I2 prevents splashing of liquid
while a container is being ?lled.
At the same 35
time, because of the irregularities of the tops of
containers, air is admitted thereto in the manner
indicated by the arrows in Figure 7. In said
Figure '7, the openings on the side and top 01' the
container I! are exaggerated for the express pur
pose of illustration.
_
As liquid ?owing down an outlet pipe I4 reaches
' a predetermined height in a container, any liquid
which may?ow into the can over and above such 45
height will be drawn through the ?ller head ID
with the air removed from a can, as indicated by
arrows in Figure 7.
As a container I2 is‘pressed against the ?anged
portion II of. a‘ ?ller head I0, said container forces 50
the ?ller head I0 upward. A tubular sleeve I3
threaded or otherwisefastened to the top of
?ller head I0 is loosely ?tted around outlet pipe
I4 so that whenthe ?ller head I0 is raised, the
sleeve I3 telescopes on outlet pipe I4. Outlet pipe 55

As ?ller head I0 is pushed upwardly, a lug on
the lower ?anged section of tubular sleeve i3
sleeves 28, equally spaced and suitably fastened
contacts a ?nger l5 fastened to the bottom end of
a valve rod I6. A pin placed in valve rod I6 con
to or forming a part of disc 54. As the disc 54 is
rotated, one container may be moving into posi
nects ?nger l5 and said rod and prevents ?nger
tion, another may be receiving liquid, a third may
be about to be lowered, another may be about
sufilciently at its outer end to permit of valve I‘! to be moved off the disc 54, and other relative
being closed manually, if necessary, to stop the positions may exist. The number of sleeves 28 in
flow of liquid from tank 6. This is necessary in disc 54 may vary according to the size of con
l5 from sliding along rod ,l6. Finger l5 projects
case of difficulty with the machine or the power
supply.
As the valve rod I6 is pushed upwardly, valve
15 I1 is opened as shown lnFigure 4, and liquidflows
down through an opening i8 and by way of outlet
tube l4. Two aligning wings 28, one on each side
of valve rod l6, either separate from or forming a
part of a valve sleeve 2|, maintain valve l1 in
20 line with opening I 8. When the operation of
.?lling a container is completed and such con
tainer is being lowered, a spring 22 on valve stem
or rod l6 bears down on ?nger l5 and urges valve
H to a closed position, thus arresting the flow of
25 liquid from tank 6. At the same time, a spring 23
about the sleeve l3 forces the filler head l8 down
wardly to a predetermined position. The outlet
tube l4 has a ?aring lower end and is of greatest
diameter at its base. This permits the ?ller head
30 III to drop only a ?xed distance.
A container I2 is raised or lowered by a cam
roller 2411 which is rotatably mounted von a stud
24b.
A's cam roller 24a travels over the face of a
cam 25, stud 24!) which is suitably attached to a
35 piston or container lifter 26, slides up or down
in a slot 2‘I'of a piston. sleeve 28. Cam 25 is of a
predetermined length and curve and is fastened
to or forms a part of the cross frame 3 and re
mains stationary.

While the operation of ?lling containers I2 is
proceeding, a fan 29, by suction, draws off air
and any surplus liquid through an opening 38 in
?ller head it and through a connection 3| between
filler head l8 and an air chamber 32. The air
thus drawn away is sucked through a pipe 33 and
45
released through an opening in an exhaust 34.
Exhaust 34 may be fastened to cross member 2
by suitable means.
.
Fan 29 is rotated by a drive chain 35. The drive
chain 35 is driven by a sprocket 36 on a shaft 31.
50 Shaft 31 is held in position in a bearing on a
bracket 38, one being at each end. Brackets 38
are fastened to standards i by suitable means.
A pulley 39 is securely keyed or feathered to
shaft 31. The pulley 39 is connected to or driven
55 by any suitable prime mover, such as a motor
directly or connected. to line shafting. As drive
chain 35 rotates a sprocket 48 on shaft 4|, a
beveled gear‘ 42 suitably fastened to shaft 4i
meshes with another beveled gear 43- on a shaft
44 Fan 29 is fastened to the upper extremity of
the shaft 44. Said shafts 4| and 44 rotate in bear
ings formed in cross member 2.

The surplus liquid, which is drawn off from
the containers I2, runs into a vessel 45 and ?lls up
65 openings 46 making the vessel air tight. As the
tainers with which the machine will be used. The
pistons 25 are arranged exactly beneath air seal
ing ?ange i l of filler head "I.
Supply tank 6 and piston disc 54 rotate in uni
son and are so joined that when the disc 54 is
rotated, supply tank 6 must of necessity also‘
rotate. This arrangement maintains the same
piston exactly below the same filler head at all
times.

The rotation of the disc 54 and supply tank 6
in unison is accomplished in the following man
ner. Chain ‘35 turning on a sprocket 55 which
is securely fastened to one end of a shaft 56 ro
tates a bevel gear 51 on the other end of shaft
56. I Shaft 56 turns in bearings 58 and 59. Bear
ing 58 is formed in a bracket 60, which is fastened
to standard i by any suitable means. Cross mem
ber 3 which holds the bearing 59 and supports
shaft 56 forms a part of the bearing for a shaft 30
62, and also forms the cam and support for pis
ton disc 54.
Bevel gear 51 meshes with another bevel gear
63 held by suitable means on one end of shaft
62. On the upper end of shaft 82 is fastened a in)
gear wheel 6| which meshes with a gear wheel
98 secured to or forming the under part of pis
ton disc 54.
Air chamber 32 is welded or otherwise fastened
at its lower extremity to the disc 54 so that when
the disc 54 is rotated the air chamber 32 is also
rotated. To the upper extremity of air chamber
32 is fastened by suitable means the lower ex
tremity of rod 8. The upper reduced portion of
rod 8 ?ts in a bearing in the cross member 5. A
recess 89 in rod 8 and a recess in tubular center ‘I
accommodate a key therebetween so that when
the piston disc 54 is rotated, the tank 6 also will
rotate in unison therewith.
A receiving disc 64 receives containers I2 which
have generally been previously ?lled with fruit,
berries, or vegetables. As the receiving disc 64
is rotated, it delivers containers i2 to the disc
54. A bevel gear 65 suitably fastened to shaft 31 '
meshes with another bevel gear 66 fastened on
one end of a shaft 61. The other end of shaft 61
is provided with a bevel gear 68 which meshes
with another bevel gear '69 fastened to the lower .
end of av shaft 10. ~ The upper end of shaft 18 is
suitably and securely fastened to the receiving 60
disc 64.

As the containers l2 ?lled with liquid rotate
with the turret or disc 54, the containers come
in contact with an ejector ‘I! which pushes the

ejector 1! remains stationary and is fastened se
curely to a bracket II which is suitably fastened
to the cross frame 3.
The discharge disc III is rotated in ‘a clock

able means.
An examination of Figure 6 will make the in
vention clear. Said Figure 6 illustrates in a dia
of the container in a direction inwardly insures
against any liquid over?owing the top of the
can.

The continuous rotation of the piston disc ll,
brings the container i2, now filled with the cor
rect ‘amount of liquid, against an ejector 19,
which ejector pushes ‘the container from disc 54
onto a, discharge disc 80. From the discharge 15
disc 80 the containers are moved to a sealing
machine (not shown) by any suitable means.‘~

1. A ‘can ‘?lling apparatus including a ?lling
duct, a head movable relatively thereto and hav 20
ing walls spaced from said duct to form an out
let port for excess liquid, and means for with
drawing air and liquid by said outlet port, the .
head being adapted‘ to project into a container,
grammatic way the principles upon which the in
the lower extremity of the projecting portion of
vention operates. Notations have been used on
Figure 6 to aid in its understanding. As the lift
ing piston 28 raises a container l2 against a filler
said head and the lower extremity of saidsduct
being in substantially the same horizontal plane
when in ?lling'position whereby any liquid there
in above the level of such lower extremities will
30
be removed.
2. In a can ?lling device, ahead for seating
head ID, a valve ii in supply tank 0 is opened
and liquid flows down the outlet tube ll. Air is
drawn through the passageways and released
through the exhaust as indicated by arrows. The
surplus liquid is drawn off and forced by liquid
pump 49 back into supply tank 6 as indicated.
A summarized description of the different op
erations from the receiving of the ?lled containers
of fruit, berries or vegetables, minus the liquid,
until the containers are ?lled with the liquid and
discharged, will give a clear conception of the
present invention.
The containers previously ?lled with fruit,
berries or vegetables are placed on the receiving
disc 64. As the receiving disc 64 rotates in a
clockwise direction, the container l2 comes in
contact with the feeder ‘II which also rotates
in a clockwise direction. Feeder ‘Ii, by reason
of its projecting ?ngers and rotation, pushes the
containers onto the piston 28 of the: piston disc
upon a can and substantially closing such can
without sealing the edges thereof, said head hav
ing a suction conduit therein and a circular
trough about said conduit externally shaped to
fit inside the rim of such can, and suction means
operable through said conduit to withdraw liq
uid from said can by drawing air between the
edge of such can and said circular trough ‘into
said conduit.
.
without sealing the edges thereof, said head hav
ing a suction conduit and a filler conduit therein
and a circular trough about said conduits exter

depend inside the rim of such can, means to ?ll
such can through said ?ller conduit, and suction

direction, studs 24 pass over cam 25 and the con
tainers are raised against flange ll which is
means operable through such suction conduit to

supply tank'ii flows through outlet l4 into the
said‘ trough into said suction conduit.
containers of fruit, berries or vegetables, as soon
55 as valve i1 is opened. As soon as the container
has been ?lled with liquid to a predetermined
height, the suction from fan 29 draws off any
surplus liquid and a pump 49 forces the surplus
liquid back into supply tank 6.
It will thus be seen that by my improved de
vice and process, and particularly due ‘to the
thinness of the ?ange ll only a slight suction is
required to raise the liquid upwardly through
the passage 30 on to the upper surface of the
65 ?ange II from which point it will ?ow into the
receptacle formed within the head Ill and then
through the discharge passage 30 to the desired
point as hereinbefore described. The fact that
the upper surface of, the ?ange i I is only slightly
70 raised above the upper edge of the can coupled
with the‘fact that the passage 30 is spaced in
wardly from the suction passage and, as shown
by the arrows in Figure '7, provides a means and
