APPARATUS FOR RE CONDITIONING THE
EXTERIOR OF CONTAINERS
Samuel F. Kimball, Portland, Maine, assignor to
The Portland Company, Portland, Maine, a_
corporation of Maine
Application October 11, 1933, Serial No. 693,13
7 Claims.
This invention relates to machines for recon
ditioning containers and particularly for that
part of the reconditioning that has to do with
the exteriors of barrels or casks.
Aside from the inherent problem of thoroughly
cleansing such containers automatically, espe
cially where they have been used'for oil and like
materials, real operating problems exist, first, in
keeping the washing and rinsing fluids separate
10 so that the maximum use may be had of each;
second, in maintaining the operation of the ma
chine while the washing and rinsing iiuids are
being renewed; and third, in adapting the ma
chine to practical Working conditions.
15
The need for such a machine and such service
has long been recognized but although attempts
have been made to provide a machine to perform
such work, most of the reconditioning is still
done by manual labor.
My concept solves the problems involved by
providing for a machine in which the washing
and rinsing fluids are kept separate. At the same
time, I provide alternate tanks for both fluids so
that one may be used while the fluid in the other
25 is being prepared, or the tank refilled or flushed
out. I also carry the containers through a driven
spray rather than through tanks full of liquid,
thus permitting the fluids to be kept in circula
tion. With my invention, therefore, containers
30 may be reconditioned without any manual han
dling as the containers will be automatically en
tered, carried through and discharged from my
machine.

These and other features will be apparent from
35 the accompanying drawings:

Fig. 13 is> a side view of the barrel release, and
Fig. 14. shows in detail the dirt screen sur- 5

`
Fig. 15 is an enlarged partly fragmentary sec
tion through the washing station.
In such a washing machine I provide a base
generally indicated at I and an upper portion 10
or framed superstructure 2 including a washing
station generally indicated at W ancÍJ'aIrinsing
station at R and a drawing station at
'_I‘he
base Iv is provided with tanks 3` and 3EL separated
by a partition 3b for washing fluid and tanks 4 15
and IIa separated by the partition 4b for rinsing
iiuid. Each of these tanks is preferably provided
with suitable heating means 5 such as shown in
the tanks 3 and 4 subject to thermostatic con
trols such as at 6.
20
Each tank is also provided with valve con
trolled inlets 1 havingl float controlled valves `|94
and valve controlled outlet drain pipes 8. -Valve
controlled suction outlets 8a lead from each ta'nk
to washing iiuid and rinsing fluid pumps 9 and 25
9a respectively.
-
'
In each of the tanks I provide scum traps I2,
always open to drain as at I3.
-
Near the front of the washing station and near
the rear of the rinsing station the door F is pro- 30
vided with drains IIB. A valve II is pivoted in
each drain and the pivots are extended to form
the handle III for the valve I I adapted to be posi
tioned to direct the liquid into either of the Wash
ing tanks 3 or 3a, andthe handle I0“ by which 35
the other valve II may be positioned to return
ltlhe rinsing liquid into either of the rinsing tanks , Y
or
a.
By these controls, it will be seen that any tank
may be isolated at ‘any time when the fluid there- 40
in is unsuited for further use without interfering
with washing or rinsing operations by turning
the valve II to direct the ñow into the lalternate
tank and by closing the valve in control of the
suction outlet 8“ for the tank to be isolated as 45
will-be apparent from Figs. 1 and-12. `When so
isolated, it may be drained, ñushed out, reñlled,
and heated so as to be in proper condition when
its alternate needs attention.
From the pumps 9 and 3B fluid conduits or 50
mains I4 lead to a series of shower devices in
the washing and rinsing stations W and R, each
shower device having an arm I5 to spray the sides
of a container and crossed spray bars I6 disposed
to discharge on the ends of the containers. '

The containers C are placed in the machine on
the slide A, and are there held by thebarrel con
trol arm I'l and the guide A'.
.
The conveyor generally indicated by C consists
of a pair of chains ` i8 carried by the sprockets
20 and 2| l. At suitable intervals; as is shown in
~Fig. 10, links in the chains I8 are provided with
fixed uprights '58 to which are secured yokes 8|
to receive cross members C' or C’.
10
Each of the cross memb'ers C’ and Cz is pro
vided with axle arms C4 (see Fig. 11) on which
are mounted for independent rotation bearings
52 formed with a flange 83 which serves as a
15 apparatus and with a flange 84 deñning with the
flange v83 a groove for the yokes 88 in which the
bearings 62 are loosely mounted.
The axle arms C* of the cross members C’. as
shown in Figs. 10 and 11, are provided with discs
20 or sprockets C’. A
v By- »this' construction, the movement of the
chain and the travel of the bearings 52 along the
- tracks |8 do not rotate the cross members.
As
I desire to _have the containers rotate, I provide
25 an auxiliary belt or chain 2| driven by any suit
able means and which contacts and rotates the
discs or sprockets C3 and the cross members C2
tionpermitting the container to roll forwardly
on to the conveyor between the cross members C’
and C’. As the arm I1 is raised, a container is
carried on to the conveyor, and the cross bar I'lb
is moved' to hold the next container on the slide
ìintil it is properly positioned on the conveyor in
urn.

Recondltioning, in many instances, implies
painting or other refinishing, and inasmuch as
for that step the containers must be dry, I have
provided a drying zone to ensure that the con
tainers will be thoroughly dried in the shortest
possible time. The size of this chamber will de
pend largely on the speed with which the con 15
tainers are passed‘therethrough and through the
washing and rinsing stations. In the drawings
I have shown _a drying unit of capacity to hold
three containers, but as description of larger ca
pacity would be repetition, I limit my description
to the. different features of the illustrative form.
The drying unit preferably consists of a cas
ing or oven 45 and an inclined floor 4| which per
mits the barrels to roll as they travel through
the o_ven.
Heating means 42 for the oven are
provided. Theentrance is provided with a swing
ing door 43 and the exit has a door 44. These
at any desired speed.
'
.
At predetermined intervals the barrel feeding doors while closed will retain the containers in
30
the oven and keep other containers from enter
mechanism, to be later described, releases a bar
ing.
Within the casing 48 container stops 45 are
rel >to position where it will be picked up by the
conveyor.

The conveyor consists of a pair of chains I5.
The chains are driven by a motor (not shown),
35 rotating the sprockets 28 on a shaft 25‘, suitably
mounted in the superstructure 2. Near the front
_ end of the apparatus are sprockets 2|' on a shaft
2lb. The shaft _2|b is journaled in bearings 38
in blocks 3| which are slidably connned in guides
40 32 on the superstructure 2. 'I‘he forward ends of
the blocks 3| lare secured to weights 34 to keep
the chain I8 taut.

The fioor F is provided with a partition F' to
prevent the mingling of -the washing andrinsing
45 liquids. Before the washed containers pass over
the partition F' into the rising station,- they are
drained. This is accomplished by lowering the
conveyor> supporting track I3 to a lower level
55
through a zone D. The conveyor is forced to fol
low the track i8 by a depressor D' disposed to
contact the ends of the cross members C' and C’.
'I'he enlarged ends C3 are thereby carried out of
contact with the belt 2| stopping rotation of the
cross members C2 and the containers.
The drainage in keach station flows from the
partition _F' towards the drains I in vwhence it is
directed to the desired tank 3-3‘ or 4-4‘ by
the valves |~|. The drains are covered by a box
like shield indicated as at lll’ in' Fig. 15. Be
60 neath this shield there is a sloped member> ||¢
over the drains ll‘, in the inner end of which
are mounted the scum retaining member 23 and
the screens 24 and 24l to retain mud and other
65
'I'he container delivering mechanism may be
best seen in combination in Fig. 15, and in de
tail in Figs. 8, 9 and 13. This comprises cams 38
mounted onthe sprocket shaft 2lb between the
sprockets 2| 'ß and bearings 38. Forwardly of the
70 sprocket bearings 38 bell crank levers I1 are plv
oted to the blocks 3|. The levers |'I are pro
vided with cam engaging ~-portions l'll and two
levers VI'l are connected by a bar | 1b. 'I'he cam
positioned. ' The stops 45 >are rods extending
transversely of the oven and are adapted to lle
against the containers to hold them on the in
clined floor 4| for a period suillcient to ensure
their dryness when delivered from the oven.
The doors 43 and- 44 are normally held closed
and the container stops 45 are normally held in
barrel engaging position by a bell crank lever 48
pivoted to a shaft 5|, and to the long arm 48*
of which- is connected a weight 58, 58* or 58h as
the case may be.
.
'
The doors 43 and 44 are swung to open position
and the container stops lowered to 'permit the
passage of the containers through the oven by
means of the connecting rod 45 which is actu-`A
ated by the crank 53 on the sprocket shaft 28'.
The connecting rod- 45 is positioned oiï center
from the sprocket 28 and is eccentrically con
nected to a disc 41 controlling the barrel exit
door 44, to discs 41", one controlling each of the
container stops 45, and a disc 41h controlling the
container entrance door 43. -
Each disc carries a catch 48 adapted to engage
a lug 48' on the short'arm 48b of the bell crank
lever- 49 on predetermined rotation of its disc
which rocks the bell crank lever against the force
of the weight 58, 58" or 55".
'I‘he bell crank lever 48 is rigidly connected to
the container stops 45 by the bar 45h which lies
parallel to the container stop 45 to which it is
rigidly connected by the arm 45* so that the stops
45 pivot with the bell crank lever. 'I‘he bar 4l"
is connected to the bell crank 48 at 454 and ñnds
bearing in the block 45° on the shaft 5| on which
the bell crank Vlever pivots.
The opening of the entrance door, the succes
sive movement of the containers through the
oven, and the opening of the exit door are syn
chronized by initial positioning of the discs rela
tive to the connecting rod 45 so that on prede
termined movement thereof, desired- contact of
70
the catch 48 on the discs and the lug 48' on the
(See Fig. 5.)
In the case of the doors, suitable connections'
38 rotates with the sprockets 2|“, and on each _ bell crank 48 is effected.
75 rotation permits the bar I1b to'drop from a P051
lead directly from the bell crank lever 449 to the 75
3
2,115,903
doors to swing them against the forces of the
weights 50--50b exactly as the container stops 45
are pivoted.
The stops are pivoted or carried
downward to permit the barrels to roll along the
oven floor when the connecting rod 4I rotates
the discs Il, 41B, 41h to position where the catch
48 engages the lug 49' to pivot the bell crank
lever 49 against the weights 50.
When the discs have revolved to an extent suf
10 ñcient to permit each container to advance to its
next position, the catch '48 and lug 49’ are dis
engaged and the weight 50 carries the bell crank
lever again to the position of Fig. 5 in which the
containers are stopped and doors closed._
The drying unit may, of course, be made sep
15
arately or integrally with the washing machine,
but it is synchronized definitely therewith in re
conditioning the barrels with the maximum eili
ciency and the minimum length of time so that
they may be reflnished by painting.
