(01. 226—-125)
This invention relates to machines for ?lling
jackets or casings with granulated material such,
for example. as ground cork, and particularly to
machines for ?lling boat fender casings, life buoy
5 casings, life raft casings, and similar casings with
granulated material such as cork.
It is an object of the invention to provide an
efficient and dependable means for ?lling and
packing the jackets or casings of boat fenders,
0 ring buoys, life rafts and the like with granulated
?lling material.
One illustrative embodiment of the machine is
shown in the accompanying drawing, in which:——
Fig. 1 is a vertical section of a machine em
1
bodying the invention and showing in association
with the machine a boat fender casing to be ?lled
and packed with ?lling material.
Fig, 2 is a sectional view of a portion of the
bit or screw which feeds the ?lling material into
21')‘ the fender casing, said view being taken on the
line 2--2 of Fig. 1.
Fig. 3 is a sectional view of the feed tube of
the machine taken on the line 3-3 of Fig. 1.
The machine of this application is adapted to
25 feed granulated material such as ground cork into
casings of various types such, for example, as
boat fender casings, ring buoy casings, life raft
casings and the like, and to tightly pack the filler
material in such casings.
Referring to Fig. l, a boat fender casing is
30
shown in association with the illustrative machine
in position to be ?lled with ?lling material. As
there shown, the fender casing consists of a cy
lindrical side wall I and an end wall 2 provided
35 with a grommet 5 through which the ?ller ma
terial may be fed into the casing and through
which a rope 6 extends. A detailed description of
the boat fender andv the manner in which the
grommet opening is closed after the casing is
40 ?lled is given in my copending application Serial
No. 754,988 ?led November 27, 1934, of which this
application is a division.
The illustrative machine is provided with a tube
4
member I5 adapted to be inserted into the casing
through the grommet 5. Secured to the upper
end of the tube I5 is a funnel-shaped member I6.
The member 16 and the tube l5 secured thereto
are supported by a bracket I'I extending from. a
framework I8 of the ?lling machine.
The tube I5 is preferably provided on its inner
50
surface with longitudinal corrugations I5’, as
shown in Fig. 3 to reduce swirling of the material
in the tube.
Extending down through the funnel member I6
55 and through the tube member I5 is a bit or screw
I9 for feeding the filler material from the funnel
shaped member I6 into the fender casing.
The bit or screw I9 preferably extends below
the lower end of the tube I5 2. sufficient distance
to permit it to spread and pack the material in
the fender casing.
The diameter of the bit or
screw preferably gradually decreases from the
bottom to the top to facilitate the feeding of the
filler material from the funnel-shaped member
I6 through the tube I5 and into the fender casing.
The edges of the spirals of the bit or screw which
lie within the tube I5 preferably are knife-edged
to reduce frictional heat and facilitate the'feed-‘
ing of the material through the tube I5.
For spreading the ?ller material outwardly
from the bit or screw and for packing it solidly
against the walls of the casing, the bit or screw
is provided near its extremity with an expander
20, the shape of which is best shown in Fig. 2.
This expander forces the filler material toward 20
the outer walls of the casing and produces a tight
packing which is impossible by hand operation.
The bit or screw I9 is journaled for rota?
tion in bearings 2I and 22 supported respectively
by brackets 23 and 24 carried by the frame I8. 25
The screw or bit is rotated through a pulley 25
fixed to its upper end through a belt 26 driven
by a motor 21.
The funnel-shaped member I6 may be kept
?lled with ?ller material through a chute 28 30
leading from a supply bin 29.
During a ?lling operation the fender casing
may be held by the attendant or supported on a
yielding support which will permit the casing to
move downwardly as it is ?lled.
As the ?ller 35
material is fed into the fender casing by the
bit or screw I9 the casing will gradually be ?lled
and tightly packed with the ?ller material. The
?lling operation will gradually force the casing
down until the tube I5 emerges from the top
thereof. The tightness of the pack will be regu
lated by the force with which the fender is sup
ported and held during the ?lling operation.
It will be noted that in the illustrative machine
the packing is done after the ?ller material 45
emerges from the lower extremity of the tube I5,
the bit I9 carrying the expander 20 extending
below the lower extremity of the tube I5. With
this arrangement the ?ller material is packed
downwardly and outwardly by the bit and the
expander and insures a tight pack.
While the illustrative machine is shown as
?lling a boat fender casing, it will be understood
that it may be used to ?ll other types of casings
or containers such as bags, drums, barrels, boxes,
2
2,114,103
ring buoys, life rafts and the like, and the ex—
pression “casing” as used in the claims is in
tended to include all such casings and containers.
It will be understood further that the machine
may be used to ?ll and pack various types of
containers with materials such as cereal prod~
ucts, ?our, feed, bran, gypsum, cement, lamp
black, molybdenum, brewers’ grains, clay prod
ucts, chemicals, linseed meal, dried milk and the
10 like, and that the expressions “granulated ?ller
material” and “?ller material” as used in the
speci?cation and claims are intended to include
such materials and all other materials which are
susceptible of being packed in a receptacle or
15 container.
It will be understood that the invention is not
to be limited to the speci?c embodiment shown
for purposes of illustration as the inventive fea
tures may be variously embodied without de
parting from the invention.
It will also be understood that all of the fea
tures of the invention need not be used con
jointly as they may be used to advantage in
various combinations as de?ned in the sub
joined claims.
