We, ISAAC BRADBURN, 71, Huskisson Street, Liverpool, in the County of Lancaster,
Merchant, and RICHARD STUBBS, 19, Aigburth Street, Liverpool, aforesaid, Mechanic,
do hereby declare the nature of this invention to be as follows:-
The invention has partly for its object, an apparatus for holding a bag or sack open
at the mouth and in an upright position whilst it is being filled, without the intervention
of a person to hold it. The invention further relates to a sieve or screen of improved
construction, applicable for use in connection with the bag holder.
In carrying out the invention we provide a holder preferably made of metal, and
approximately the shape and size of the mouth of the sack or bag. It is made in two
parts, which are hinged or pivoted together, one of the parts being attached to a
framing, so as to hold it firmly in the required position. The hinged part is provided
with projecting pins or catches, which engage the handles of the sack, or otherwise
grip it and hold it in an upright position. The framing is provided with hooks so that
it can be secured to a wagon or cart.
This framing is made so as to support a sieve or screen above the vehicle from
which the sacks are to be filled. The sieve is provided with rollers or wheels preferably
one on each side, supported on rails attached to the said framing, so that the sieve can
be moved to and fro thereon. If the sieve is provided with two wheels, we provide
a plate or spring attached to the framing, so as to prevent it falling over. It is also
preferably held by springs or in an equivalent manner above the vehicle, so that
when it is moved on the rails it will always travel back again to, its normal
position.
The mode of action is as follows:
The sieve is filled with the substance to be screened, and is moved to and fro, so that
the screenings fall back again into the cart. The operator has only to draw the sieve
towards him, the springs above described pulling it back again. The spring or springs
for preventing the sieve from falling over are sufficiently flexible to allow it to be

page_text: tipped and thus the contents can be poured into the sack suspended from the holder,
and placed ready to receive it. The handles of the sack are attached to the projecting
pins and the mouth of the sack is placed around the holder, which is preferably
slightly larger than the mouth of the sack, so that when the sack is attached the
hinged holder is not quite fully open. As the sack is filled, its increased weight will
pull or drag one side of the sack (namely the side furthest from the projecting pins)
off the holder, and the hinged part of said holder being therefore released will imme-
diately collapse or drop. The holder is preferably at such a height when the holder
drops, that the sack will be deposited on the ground. The handles can then be removed
from the projecting pins, and the filled sack replaced by an empty one, so that the
operation can be repeated. We generally provide a trough or channel conveniently
attached to the framing into which the material is tipped from the sieve and delivered
into the sack.
In place of projecting pins for fastening the sacks to the holder we can provide clips
or if preferred, pegs somewhat similar to clothes pegs.
Our improved sieve may be constructed as follows:
The frame or sides are circular or other shape preferably made of thin sheet metal.
It is cut or parted at one side and the two ends thus formed securely connected together
by bolts or other suitable fastening. At or near the bottom of the frame, and on the
inside thereof, is formed a groove, preferably semi-circular in section, though other
shape may be employed.
The sieve is formed of wire secured to a round, flat, or other shaped ring, corre-
sponding in shape and size with the above mentioned groove in the frame. The mesh
can of course be regulated by the number of wires employed. To insert or remove
the sieve from the frame the bolts are unscrewed, and the frame can then be opened
sufficiently to allow the sieve to be inserted in or removed from the groove.
The groove
could be omitted if desired and the ring simply fastened to the frame by bolts, or in
an equivalent manner.
The wires are fastened to the ring in any ordinary manner. When any breakage or
damage of the wires occur, the sieve can be removed, and a fresh one inserted, or the
damaged wire can very readily be replaced.
It is evident that the sieve may be formed of perforated metal if preferred, and
secured to the frame in a similar manner to that already described. It is also
obvious that the frame may be made of other material besides metal, such as wood,
etcetera.

page_text: Improvements in or relating to Filling Bags or Sacks and Apparatus
Applicable for Use in Connection therewith.
We, ISAAC BRADBURN, 71, Huskisson Street Liverpool, in the County of Lancaster,
Merchant, and RICHARD STUBBS, 19, Aigburth Street, Liverpool, aforesaid, Mechanic,
do hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement-
The invention has partly for its object, an apparatus for holding a bag or sack open
at the mouth and in an upright position whilst it is being filled, without the interven-
tion of a person to hold it. The invention further relates to a sieve or screen of
improved construction, applicable for use in connection with the bag holder.
The accompanying drawings show one convenient form of apparatus embodying our
improvements. In these:-
Figure 1 is a front elevation showing the bag in section.
Figure 2 is a side elevation.
Figure 3 is a plan with the sieve or screen removed.
Figures 4 and 5 are respectively back elevation and plan of the screen, parts being
broken away to show the internal construction.
In carrying out the invention we provide a holder preferably made of metal, and
approximately the shape and size of the mouth a of the sack or bag A, this holder
being preferably rather larger than the mouth of the sack as shown. The holder is
male in two parts B, B', which are hinged or pivoted together as at b, one of the
parts B, being attached to a framing C, C, so as to hold it firmly in the required
position. The hinged part B¹ is provided with projecting pins or catches b¹, which
engage the handles a' of the sack, or otherwise grip it and hold it in an approximately
upright position, as seen in Figure 2.
Or in place of projecting pins for fastening the sacks to the holder, we can
provide clips, or if preferred pegs somewhat similar to clothes pegs.
Or the pins or clips might be dispensed with in some instances, and the mouth of
the sack be simply distended by being placed' round the holder before the latter is
straightened out, and by then forcibly straightening the holder.
The part of the framing may be provided with hooks c, by which it may be
secured upon the side of a wagon or cart, or upon a cross bar (2 supported by suit-
able portable or fixed standards C³. Or the framing may be otherwise fixed in any
suitable position. The part C and the cross bar Care preferably each adjustable as
shown upon the part and standards C³ respectively.
The framing also supports a sieve or screen D at a suitable distance above the
vehicle, or other point from which the sacks are to be filled. The sieve is provided
with rollers or wheels d preferably one on each side, supported on rails C, attached
to the said framing so that the sieve can be moved to and fro thereon. If the sieve is
supported on two wheels only, we provide a spring or a supporting plate or frame C¹³
attached to the framing to prevent it falling over, the axis of the wheels d being so
placed that the sieve has always a tendency to rest with its rear edge upon the frame C³.
The sieve may also be held by springs, or their equivalent, so that when it is moved

page_text: forward on the rails (*, it will always travel back again to its normal position, when
free to do so. Or the rails may be simply inclined as shown, so that the sieve runs
back by its own weight.
A trough or shute E may be attached to the front side of the sieve, so as to move
therewith, or it may be fixed upon the framing C When attached to the sieve it is
convenient to provide the front end of the shute with handles e, by which it and the
sieve may be tipped up when discharging the contents.
The sieves we prefer to use may be constructed as follows:-
The frame or sides D¹ are circular or other shape and are preferably made of thin
sheet metal. The frame is cut or parted at one side as at di Figures 1, 4 and 5, and
the two ends thus formed are securely connected together by bolt d² or other suitable
fastening. The parted ends of the frame are shown overlapping and the bolt d² is
passed through them, though, of course, other modes of fastening might be employed.
At or near the bottom of the frame, and on the inside thereof, is formed a groove d³
preferably semicircular in section, though other shape may be employed.
The sieve bottom is formed of wire D2 secured to a round, flat, or other shaped
ring D³, corresponding in shape and size with the above mentioned groove in the
frame. The mesh can, of course, be regulated by the number of wires employed.
To insert or remove the sieve bottom from the frame the bolts are unscrewed, and the
frame can then be opened out sufficiently to allow the bottom to be inserted in or
removed from the groove. The groove could be omitted, if desired, and the ring
simply fastened to the frame by bolts, or in an equivalent manner.
The wires are fastened to the ring in any ordinary manner.
When any breakage
or damage of the wires occurs the sieve can be removed, and a fresh one inserted, or
the damaged wire can very readily be replaced
It is evident that the sieve bottom may be formed of perforated metal if preferred,
and may be secured to the frame in a similar manner to that already described. It is
also obvious that the frame may be made of other material besides metal, such as
wood, etcetera.
The mode of operation is as follows:-
To secure the bag to the holder the front or hinged part B¹ is turned up as shown
in dotted lines in Figure 2. One side of the bag mouth a is slipped over the fixed
portion B of the holder, the handles a are placed over the pins and the hinged
part B pushed down into an approximately horizontal position. This draws the
handles taut, and the bag hangs securely in the position shown, until it is almost or
quite full, when the rear edge of the mouth is drawn off the part B by the weight of
the contents and the bag is held solely by the pins b'. The weight upon the pins now
causes the hinged part B¹ to collapse as shown in Figure 3. The holder is preferably
adjusted to such a height that when it collapses the full bag is deposited in an upright
position on the ground or platform below it. The handles can be now readily slipped
off the pins, and the filled bag removed and replaced by an empty one.
In using the sieve, the operator in the cart or other position fills it with the material
to be sieved or screened. He, or the operator on the ground or platform below, or
both of them, now move the sieve to and fro upon the wheels d so that the screenings
fall back into the cart or on the outside of it, as desired. The operator below now
draws the screen towards him and tips it up as shown in dotted lines in Figure 2, so
that the contents, are shot into the bag A below it.. On releasing the shute and sieve,
the weight of the latter, or the pull of the spring attached thereto, causes it to assume
its horizontal position, and it rolls back into its normal position by the inclination of
the rails C, or the pull of the springs aforesaid, being prevented from capsizing by
the frame (³.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:
1. A collapsible sack or bag holder consisting of a jointed frame such as B, B¹,

page_text: a collapsible or hinged part B¹, provided with pins or catches or their equivalent,
adapted to receive and retain the handles of the sack or the opposite side of its
mouth in such a manner, that on the straightening of the said collapsible part, the
sack is held in position with its mouth extended.
2. A collapsible sack or bag holder, consisting of a fixed part B, and a hinged
part B', to both of which the sack is secured in such a manner that when empty, it
is held suspended with its mouth extended, but when filled, or nearly filled, its weight
detaches it from the fixed part B and causes the hinged part B to collapse and
deposit the filled sack in an approximately upright position on the ground, or platform
below it, substantially as described.
3. In an apparatus for filling bags or sacks, a sieve or screen consisting of a loose
bottom such as D², D³, and of a frame D¹ (preferably circular) and provided with a
retaining groove d³ or its equivalent, for the reception of the said bottom, and with
means whereby the latter may be readily changed and removed when desired, sub-
stantially as set forth.
4. The combination with a collapsible bag holder, such as described, of a
framing C, O, supporting the same in a suitable position, a sieve D supported in an
approximately horizontal position upon said frame above said holder, in such a
manner that it may be reciprocated or tipped up as desired, and a discharge trough
or shute E fixed to said framing or sieve, substantially as and for the purposes
described.
5. The process of filling bags or sacks with coal or the like, which consists in
throwing the material into a movable tip riddle where it is riddled by oscillation
or otherwise, then moving the tip riddle and tipping the contents into a bag or sack
so held by mechanism as to be released when full.
6. The improved apparatus for filling bags or sacks, taken as a whole and
constructed substantially as shown and described.
