Genevieve A. Kendall, Potsdam, N. Y.
Application May 13, 1935, Serial No. 21,176
11 Claims.
My invention relates to a machine for cleans
ing receptacles and the covers thereof, and more
especially milk cans and covers for said cans.
One of the objects of the invention is to pro
5'1 vide improved mechanism for reversing the cans
from an inverted position to an upright position
entirely by mechanical means, and maintaining a
proper relation between a can and its cover, so
that the cover can be applied to the can at the
104 delivery end of the machine.
Another object of the invention is to provide
mechanism for moving the cans from station to
station so that the cans are properly located at
15 5
the successive stations.
The invention will be best understood by ref
erence to the accompanying drawings, forming a
part of this speci?cation.
Figs. 1 and 1a are side elevations of a single
line straight line washer, showing the general de
20.v sign of the machine and how some of the more
important members are assembled.
Fig. 2 is a side elevation showing the means
for producing the compounding movement for
indexing the can into the inverter, the length of
25» this last compounding movement being greater
than the distance between the stations of the
machine which are anterior the inverter.

crank pin I29 mounted in a boss thereof. T-bars
95 have depending arms 82, which are connected
to a cross-pin 19 which passes through a bearing
of pitman 18, so that pitman 18 can turn relative
to cross pin 19. Hence a single pitman 18 moves
the T-bars 95 back and forth in. unison. This
pitman 18 is connected to crank pin I29.
In moving the can from position K (see Fig. 2),
into the can inverter, as designated by position
D, the can has a greater distance of travel B
than in its previous intermittent movements
from station to station. The length of each said
previous movement is designated by A. This
longer ?nal feeding movement is secured by com
pounding the movement of the last pair of in 15
dexing ?ngers 9| (see Fig. 3), this being desirable
so that the inverter bars I04 (see Fig. 2), will not
contact with the milk can while it is in position K
and while the inverter is being turned.
This compounding movement is accomplished 20'
as follows:
4
Can indexing ?ngers 9! (see Figs. 2 and 3)
are pivoted by pins M2 to slidable bars 93. Said
slidable bars 93 are slidably mounted in slide
bearings Ill, said bearings Hi being mounted on
the T-bars 95.
'
Pitman members 89 are pivotally connected to
the respective slidable bars 93 at 99, and each
said pitman 89 is pivoted to a lever 83 at B5.
Said levers 83 are pivoted to a frame member F
at 84. The levers 83 are caused to rock forward
and backward by links 8T, which are pivotally con
nected to the respective depending arms 82 of T
bars 95 at 88, and each link 87 is pivotally con
nected to a lever 83 at 86. The slide bars 93 are
thus actuated in unison. As shown in Figs. 1 and
2 the cans are fed into the machine at the left
hand end of Fig. 1.
Since each depending arm 82 is rigidly connect
caused to rock backward if the normal operation

Fig. 8 is an end elevation of Fig. '7.
Fig. 9 is an end elevation showing the means respective depending arm 82. However, pivot
for mounting the motor 50 as to enable it to rock point 85 will have a longer stroke than point 86,
how the motor is mounted so that said motor is
45" backwards.
The machine has a main frame to which the
other parts are connected.v Said main frame
comprises steel channel-irons F.
' ‘
The mechanism for indexing or feeding the
50‘; cans in successive intermittent strokes, from sta
tion to station of the machine, and ?nally into
the inverter, is generally shown.
As shown in Fig. 1a, the reciprocating move
ment of the can indexing-mechanism is pro
55' duced by the rotation of gear 8|, having the
since 35 is at a greater distance than 86 from
pivot 84, and consequently this longer stroke will
be transmitted to the slide bars 93 and the supple
mental indexing fingers 9| which are mounted on
said slide bars 93.
The slide bars 93 have the full stroke of the 501'
T-bars g5, plus the extra stroke of pitman 89 over
pitman 81.
The outer ends of ?ngers 9| carry pins I [4.
At about the end of the'forward stroke of the
?ngers 9|, pins H4 will contact with the heads
2
2,129,137
of adjustable bolts 92’, which are connected to
the frame of the machine, so that the ?ngers 9I
will assume an inoperative position.
Near the
end of the backward stroke of indexing ?ngers
9i, the pins I I4 (see Fig. 3) will contact with the
heads of adjustable bolts 92 which are connected
to the frame of the machine, thus causing the
?ngers III to rotate on their pivot pins H2, and
the ?ngers will then be turned into the oper
10 ative position illustrated in Fig. 3. While the

revolution, thus inverting the can and depositing
same on stationary can trackbars H5 (see Fig.
2). The tops of bars I I5 are lower than the tops
of bars 94, but substantially flush with the in
verter bars I04, so the can, when inverted to po
sition E, will rest on can track bars H5 and in
25 verter bars I04. Can ejector members I31 are
connected to and they move in unison with slide
bars 93, so that upon the next forward move

eter, and the gear II'I has one half the diameter
of the gear IIO‘ so that there is a gear ratio of 1
to 2 between the gear II‘! and the gear I ID.
The shaft I01 of the inverter is mounted in
bearings I09 as shown in Fig. 8.
30
The can inverter is shown in detail in Fig. 1
and Figs. 5-8 inclusive.
Frame I05 and abutment member 20 are fas
tened to shaft I01. As shown in Fig. 5, the frame
I05 has a rectangular shape, having side bars 35
and end bars.
To frame I05 are welded spacers I06 to which
are welded four bars I04, as shown in Fig. 5.
Bars I04 are rigidly fastened together by bars
I08. The can inverter is assembled in the ma 40,
chine so that its bars I04 are located between the
can track bars 94 and H5. When the inverter is
turning of the can inverter in a single direction.
This improved can inverter is the ?rst which
bottom pair of bars I04 are ?ush with the tops
inverted can and move it out of the outlet side
30 of the inverter, at the same time that a can is
being indexed into the inlet side of the inverter
by ?ngers 9I. Said can ejector members I37 are
located above the bottom bars I04 of the inverter.
The ejector members I31 are connected to rods
~ I30, which are connected to bars 93, and the rods
I38 slide in bearings I39.
The intermittent turning of the can inverter
is produced by a pair of intermittent gears
forming part of the gear train shown in Figs. 7
40 and 8, this train of gears producing the recipro
cating movement of the can indexing mechanism
45 operates wholly by positive mechanism, thus elim
inating the use of the force of gravity, thus pro
viding a positive and accurate method of invert
ing a can which is of great value, as it is impera
tive that the inverting of the cans be accom
50 plished in a de?nite and precise manner, in or—
der to prevent cans from becoming jammed in
the machine. Likewise, it is the ?rst inverter
which is turned in a single direction, instead of
being rocked.
The train of gears (Figs. 7 and 8) functions as
follows:

of track bars II5, whose tops are lower than the 45
tops of track bars 94.
This arrangement permits the can to enter the
inverter on track bars 94 and to leave the in
verter on track bars H5. The members I31 pro
vide sufficient indexing movement for the ejected
can, in order to provide clearance for bars I94
when the inverter is turned.
The can indexing mechanism is positively op
erated at all times and it is superior to the pawls
which are now commonly used.

The peripheries of the shoes H8 and I20 are
shaped to permit the gear I IT to make a com

revolution. The shoes H8 and I20 then reach
the respective positions which are shown in Fig.
7, so that as the teeth I2Ia go out of mesh with 1O
nism into the inverter, they slide on stationary
mechanism, the inverter will make one half of a

Keyed to shaft I29 is a driving intermittent or
mutilated gear I2 I, having teeth I 2 Ia on one half
its circumference only, the other half being pro
vided with a shoe I20. The periphery of said
65 shoe I20 is circular and concentric with shaft
I26, save that the ends of said shoe I20 are
rounded. Said shoe I20 has a periphery of T80°
The radius of the periphery of shoe I20 exceeds
the pitch radius of gear teeth I2Ia of gear I 2|.
70 Driven gear III has teeth over its complete cir
55
of the cans, so there is no reciprocating mecha
nism beneath the cans.
When a can is introduced into the machine, it
is placed in inverted position 'upon the plate I64. 60
In said position the can is pushed into the ma
chine by means of dog IIS'I, which is pivoted at
I68 to an extension of T-bars 95.
When a cover
Ca is introduced into the machine it is located
upon the upper track bars I8, in the position 65
shown at the left-hand side of Fig. 1. The dog

the cover into the machine, from its initial posi
tion.

Cover feeding dogs II) are pivoted at I84 to re
ciprocating longitudinal cover-feeding dog-bar
I46. Stops I44 limit the lowest positions of dogs
In and stops I4‘I limit their uppermost positions.
The stops I44 and I4’! are transverse bars, con
nected to the longitudinal bar I46, which is con
nected to bar I4Ba. Bar MM is connected to bar
I46, by vertical bars I461).
During the forward movement of bar I 46 the
10 dogs Ill pivotally attached thereto will engage the
covers and index them at one station. The hold
ing dogs 9 ‘which are pivoted at I43 to a station
ary frame member, fall behind the covers and
prevent their being moved backward upon the re
15 turn stroke of bars I46 and I tea. When bars I45
and M?a are moved rearwardly, dogs 9 hold the
covers against rearward movement, and dogs Ill
then rise, slip over the covers, and then fall be~
hind the covers for the next feeding stroke.
The covers are discharged into a chute I5I
20
down which each cover slides by gravity to the
uprighted can on which the cover is retained in
a tilted position.
Referring to Fig. l, a crank 83’ having a pin 86
25 is keyed to shaft I26. This is also shown in Fig. 8.
Said pin 80 is connected to link 30!], which is
pivoted at 300a. to bell-crank lever 3M, pivoted at
302 to the frame of the machine. Bell-crank
lever 3UI is pivotally connected at 302a. to link
30 3433 which is pivotally connected at 304 to a de
pending arm of cover-indexing bar I46a. Re
ferring to Fig. 1, the pins 81! and I29 are non
aligned, so that when a can and cover are intro
duced into the machine, said can and cover are
35 not indexed in unison. The can and cover may
each have the same number of intermittent feed
ing movements through the machine, but the re
spective feeding strokes are not in unison, and
they do not have the same distance of travel.
40 That is, at every movement of a can, it is moved
the same distance, save for the compounded
movement into the inverter, and possibly the ?rst
movement produced by dog I61. Every move
ment of the cover has the same distance of travel,
save when the cover enters the chute I5I. .I-Iow
- ever the movement of a cover will be greater than
the movement of a can, since the stations for the
cover are spaced a greater distance than the sta
tions for the can. The stations for the cover are
50
therefore not superposed relative to the stations
for the can.
In the ?rst position of the can within the ma
chine, the milk residue is allowed to drain out of
the can. In the next two positions, the can is
pre-rinsed, said pre-rinsing being carried on in
two stages.
In the ?rst pre-rinsing stage I can use ordi
nary cold water from a city line or the like. In
the second pre-rinsing stage I can use cold water
or warm water which may be supplied from the
city lines and which may be led through any suit
able heater.
The next operation is the ?rst washing stage
which is performed by means of water having any
suitable cleansing material in solution. The
wash water is supplied to the nozzles W under
suitable pressure, from the tank T, by means of
the pump 47.
The next operation is the “sterile rinse,” using
70 sterile rinse water from any suitable source.
The can is then subjected to a series of steam
ing operations, three steaming stations being il
lustrated.‘ The steam for said operations is
drawn directly from a suitable boiler

The. can is now dried, two drying stations being
shown in this machine.
The can is now indexed into the inverter, and it
is then inverted.
Fig. 1 shows the pipe line I00 which supplies
Wash water to the head II, which washed the cov
ers.
Fig. 1 also shows a steam ejector ‘Hi2 which
draws water out of a suitable tank and forces the
same through the nozzles ‘I63 and ‘FM for sterile 10
rinsing of the cover. The nozzle 'IMa supplies
the sterile rinse water for rinsing the inside of
the can.
Fig. 1 also shows the washing heads ‘565 for
rinsing the outside of the can with sterile water. 15'
.Fig. 1 also shows washing heads ‘I'M for sup
plying wash water to the outside of the can.
A safety device is provided for disengaging the
gear I22 from the gear I19 and thus stopping the
entire drive of the machine if a can becomes 20'
jammed or if the operation of the machine re—
quires more than normal power.
Referring to Figs. 7 and 9, the motor IE3 is
mounted upon a platform 880 and said platform
89!] is provided with depending lugs which are 25.
connected to a shaft 8IlIa, said shaft 86m. being
mounted in suitable bearings BIO which are con
nected to the frame of the machine. The plat
form 800 also has depending lugs 805’ which can
abut the frame F, as shown in Fig. 7. The plat 30.
form 800 is also provided at its rear end with up
standing lugs 8000. to which a lever 805 is pivoted
at 805a. Said lever 885 is also pivotally con
nected at 301 to a lug 806 which is rigidly con
nected to the frame of the machine. The lever 351
895 is pivotally connected to an upwardly extend~
ing link 80m whose length may be adjusted by a
turn-buckle device or the like.
The upper end of the link 8M has a hook

frame of 40
the machine and said lever 802 is provided with
an adjustable counterweight 884.
As previously stated, the gear I!!! turns in the
counterclockwise direction. Hence the reaction 45
of the gear I22 tends to turn the platform 800
in the counterclockwise direction around the
shaft Bill. This tends to lower the rear end of
the platform and to lower lugs 800a, so that
lever 8% is turned downwardly on pivot 801, thus
pulling down link 80m.
The counterweight 804
is adjusted so as to supply the necessary driving
force for the machine. If this driving force ex
ceeds the desired limit at any time, the reaction
on the gear I22 causes the platform 899 to turn
counterclockwise. The bell crank 8I2 which is
connected to limit switch L, which is normally
held by spring La in the circuit-closing posi
tion shown in Fig. '7, is actuated by rod film, the
lower end of which is connected to platform 80!). 60
The platform then trips the limit switch L, thus
opening the circuit of the electric motor I23.
The lugs 805’ limit the turning of the platform
in the clockwise direction. The latch 8i Ia which
is pivoted at BI I, may also be provided for hold
ing the platform 78%, in the position in which
the switch remains tripped.
The latch BI Ia as
shown in Fig. '7 is in its inoperative position, but
when the platform 8% is rocked counterclock
Wise, the latch BI id will turn by gravity so that 703
its shoulder will engage platform 80D and hold
same until the latch is manually released.
I have shown preferred embodiments of the
invention, but numerous changes and omissions
could be made without departing from its spirit.
