4 Claims.
This invention relates to bag holders, and with
regard to certain more speci?c features, to auto
matic bag holders for use on the ends of ?ller
spouts and the like.
Among the several objects of the invention may
be noted the provision of a bag holder which will
receive and automatically open a bag mouth as
a bag is applied thereto; the provision of a bag
holder of the class described which‘ requires only
lo a simple operation for bag application and which
will automatically and positively grip the bag to
hold it for ?lling; the provision of apparatus of
H, or-
this class which effects a quick and easy release
of the ?lled bag; the provision of apparatus of
the class described which employs no holding
elements which puncture or otherwise mutilate
(Cl. 248-401)
used with or without ‘other machinery. This
spout l is provided with a ?ange 3 to which is
bolted the holder herein described.
The holder per se comprises an attaching flange
from which depends a smooth metal sleeve 1
of a generally cylindric form having chordal side
wise ?ats 9. The peripheral distance around
the sleeve ‘l, including the distance along the
?ats 9, is substantially equal to the peripheral
distance around the mouth‘ of a bag, that is, the < 10
bag mouth is adapted to fit snugly, but not tightly,
around said sleeve l. The ?ange 5 thus provides
a holding surface.
Depending from the front and rear portions of
the sleeve ‘l are hollow, triangular, bag-entering ~
or spreading guides ll.
These in plan View are

From the above, it will be seen that a bag,

In order that the portions of the bag mouth
receives pulverulent or granular or likematerial
adjacent the ?ats 9 may be positioned ?atwise
from some source, such as from a weighing ma
against said ?ats 9, there are provided pairs of
chine or the like, to deliver the same to bags or
the like positioned below the spout. The spout guide ?ngers l9 adjacent to, but spaced slightly
Ii is a class example of any spout that might be from said ?ats. These ?ngers l9 having out 55
2
2,126,163
wardly directed ends, in contradistinction to the
inwardly directed ends of the ?ngers l3, so that
in cooperation with the ?ngers | 3, a V-shaped
guide is effected for the portions of the bag which
are to be applied to said ?ats 9.
.
Depending from the ?ange 5, behind the ?n
gers I9, are pivot supports 2| on the lower ends
of which are pivoted radial holding ?ngers 23
which lean against the ?ats 9 of sleeve 1. The
10 ?ngers 23 are moved toward the dotted-line po
sition shown in Fig. 4 upon application of the
bag | 5 to the sleeve 1. In the solid-line positions
the ?ngers 23 gravitate and lean against the ?ats
9 to automatically grip the bag against outward
15 movement from the holder.
The ?ngers 23 ro
tate in substantially vertical and radial planes.
The ?ngers 23 are detailed in Figs. 5 and 6
and each, on its gripping end comprises a seat
25 against which is drawn, by means of draw
20 screws 21, a holding block 29, the latter ‘clamp
ing and holding in position a resilient facing 3|,
such as leather, rubber or the like. Each block
at its outer end carries a tail piece 33 adapted
to be engaged by a releasing ?nger 35.
The
25 ?ngers 23 lie in a vertical plane which is normal
to the ?ats 9.
The releasing ?ngers 35 are carried on oppo
site ends of a rock shaft 31 rotatable in bearings
39 extending from the rear of the ?ange 5. One,
30 of the ?ngers 35 is integrally associated with a
control lever 4| so that both ?ngers 35 are si
multaneously operated by said lever. The ?ngers
35 and rock shaft 31 form a releasing fork span
ning the holder and operated by the lever 4|.
From Fig. 4, it will be seen that the relation
35
ship between the resilient pads 3| and the flats
9 are such that in the downward positions of
said pads there is a more or less tangential move
ment between said pads and the ?ats 9 as they
40 come together, but the pads do not clear the
faces. Hence the effect of a toggle is had for
gripping, that is, increase in bag separating tend
ency increases the holding force. Operation of
45
the device is as follows:
While the mechanism associated with the out
let I for sending down material (not shown) is
shut off, the handle 4| is in the position shown
in solid lines in Figs. 1 to 4. It normally gravi
tates to this position. Under these conditions the
50 weights of the pad ends of the ?ngers 23 are
enough to cause the pads to lean against the
sleeve 1.
.
The bags which it is preferable to apply to the
folder are of paper or like relatively stiff ma
55 terial. Because of the stiffness they may be
pushed from their bottoms without collapse, pro
vided the endwise force resisting the push is not
too much. The present device avoids any such
excessive resistance. The bag being applied has
60 its mouth slightly opened, and the opening need
not be much. The slightly open mouth is then
pushed up, whereupon the guide ?ngers | | enter.
The mouth then slips up over the guide ?ngers
l3 and within guide ?ngers l9. This automati
cally pushes the mouth of the bag over the
sleeve 1. In moving upwardly, the mouth of the
23 are moved downwardly enough to grip or
wedge the side of the bag at the ?ats 9. The
gripping effect increases with the weight applied
to the bag.
The open character of the triangular guides
| | and the open space between the ?ngers | 3,
effects low interference with the ?ow of the ma
terial from the spout |.
After a bag has been ?lled to a suitable degree,
the material supply is cut off and then the lever 10
4| is pulled forwardly, whereupon the ?ngers 3|
are depressed against the tails 33, to raise the
?ngers 23 from the solid-line position shown in
Fig. 4 to the dotted-line position shown therein.
The lever provides the necessary mechanical ad 15
vantage for breaking the wedge hold. The ?n
gers then positively clear the bag so that it may
drop clear to the hands of the operator or to a
suitable support. Then by releasing the lever 4|,
it gravitates back into the position shown, the 20
?ngers 23 lightly fall against the ?ats 9 for the
application of the next bag. At this time wedg
ing is nil and hence the next bag readily pushes
up the ?ngers.
Among the advantages of the invention are 25
that relatively stiff bags, such as paper bags, need
have the mouths thereof opened only slightly
before application to the holder. Thereupon,
the bags need only be pushed upwardly and re
leased, whereupon they are automatically held 30
ready for ?lling. Likewise, release of the bags
from the holder, after ?lling, is as simple, the
same being effected merely by pulling forward
the lever 4|. This release causes the bag to drop.
In View of the above, it will be seen that the
several objects of the invention are achieved
and other advantageous results attained.
As many changes could be made in carrying
out the above constructions without departing
from the scope of the invention, it is intended 40
that all matter contained in the above descrip
tion or shown in the accompanying drawing
shall be interpreted as illustrative and not in
a limiting sense.
We claim:
1. In a bag holder, a sleeve over which the
45
mouth of the bag is adapted to be positioned,
said sleeve having a partial substantially circu
lar form, with chordal ?at sides, open, triangu
lar guide portions chordally arranged normally 50
to said ?at surfaces, and guide ?ngers depend
ing from said ?at surfaces and directed to have
their ends lie within a ?gure bounded by the
forms of the triangular portions.
2. In a bag holder, a sleeve over which the 55
mouth of the bag is adapted to be positioned,
said sleeve having a partial substantially circular
form, with chordal ?at sides, open, triangular
guide portions chordally arranged normally to
said ?at surfaces, guide ?ngers depending from 60
I movement of the bag downwardly, but only
said ?at surfaces and directed to have their ends
lie within a ?gure bounded by the triangular
portions, and guide ?ngers spaced from said last
named guide ?ngers and having ends arranged
to form a tapering guide for the portions of bag 65
mouths directed toward said ?ats.
3. A bag holder comprising a ?ange, a sleeve
depending from said ?ange, said sleeve having
a partial substantially round form with relatively
limited ?at sides, open triangular guides depend 70
ing from said sleeve on the round form, guide
?ngers depending from said sleeve atv the ?at
portions and directed to have their ends enter
bag mouths which are entered by said triangular
75 enough that the gripping ends 3| of the ?ngers
guide portions, guide ?ngers adjacent said ?at 75
bag pushes the gripping members 3| upwardly
from their leaning positions. The bag mouth
slides under the members 3| which then lean on
70 the bag material.
Next, the operator needs only to release the
bag and start a ?lling operation from the spout
|. The weight of the bag itself causes incipient
2,126,163
portions and spaced therefrom, said last-named
guide ?ngers having outwardly directed portions
to form with said ?rst-named guide ?ngers taper
ing guides adapted to lead portions of bag mouths
to said ?at portions, pivot means depending from
said ?ange adjacent the ?ngers at said ?ats,
oscillating ?ngers pivoted to said pivot means
adapted to gravitate downwardly against said
?ats, and adapted to be passed by bag mouths
10 applied to the ?ats and to grip the mouths upon
incipient movement 'of the bags from the ?ats.
4. A bag holder comprising a ?ange, a sleeve
depending from said ?ange, said sleeve having
a partial substantially round form with relatively
15 limited ?at sides, open triangular guides depend
ing from said sleeve, guide ?ngers depending
from said sleeve at the ?at portions and directed
to have their ends enter bag mouths which are
entered by said triangular guide portions, guide
20 ?ngers adjacent said ?at portions and spaced
3
therefrom, said last-named guide ?ngers having
outwardly directed portions to form with said
?rst-named guide ?ngers tapering guides adapted
to lead portions of bag mouths to said ?at por
tions, pivot means depending from said ?ange
adjacent the ?ngers at said ?ats, oscillating ?n
gers pivoted to said pivot means adapted to gravi
tate downwardly against said ?ats and adapted
to be passed by bag mouths applied to the ?ats
and to grip the mouths upon incipient movement
from the ?ats, said ?ngers being arranged for
movement in a plane normal to the ?ats and
having outward extensions, and means manually
controllable from a single element adapted si
multaneously to contact said extensions to si
multaneously move said ?ngers to releasing po
sitions.
