I THOMAS MCDONALD of Air Street Sculcoates, Hull in the County of York, Oil
Mill Foreman and press Wrapper Maker do hereby declare the nature of this invention
to be as follows:-
In the construction of Wrappers or Envelopes as heretofore, the body or corrugated
part of such appliances were made of wood, paper, or hair.
According to this my said invention I employ in the construction of wrappers a
combination of iron or metallic holding frame and compressed seeds or compressed
meal.
The backing of the Wrapper is preferably of wire, its borderings are of iron strips
welded to each other or secured by means of rivets or otherwise secured or of wood
secured to the backing by pins. The recessed inner space constituting the corrugated
body of the wrapper is then filled in with oil seeds, linseed meal, cotton meal, pollard
and rape dust combined, or other liko compressable seed or meal, this is next
compressed by means of a corrugated die or pressing piece, and the material so
compressed and formed, is then ready for the usual "facing" of tin or sheet metal.
The seed or meal body of the wrapper as above described not only forms a solid
durable part of the Wrapper (but it is also a non conductor of heat), and when worn
or shaken, can be removed from the framing and worked or ground up, along with
other seeds or meal and is so further utilized.
The appliance for facilitating filling the bags, consists of an oblong mouth piece,
and holding piece, for holding fully extended the mouth of the bag, and for suspending
the same.
The mouthpieces I binge or otherwise mount upon radius arms, capable of being

page_text: revolved, or they are mounted so as to have endwise or lateral movement, thereby to
bring the several bags into position, under the breech or discharge from the "kettle."-
The inouthpiece is of form and dimensions to nearly or about fit and fill the mouth
of the wrapper the effect is to distend the wrapper, and as the latter is suspended from
hooks or pins at opposita ends of the mouthpieco, the wrapper is open from top to 5
bottom so that there are no folds or creases, unoccupied by seed or meal, which is free
to drop to the bottom of the wrapper and to fill the same evenly and regularly to the
required height.

Improvements in Envelopes or Wrappers Employed in Oil Seed
Crushing and in Appliances for Facilitating Filling Oil Press
Bags.
I, THOMAS MCDONALD of Air Street, Sculcoates, Hull in the County of York, Oil
Mill Foreman, and press Wrapper Maker 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 :-
In the construction of Wrappers or Envelopes as heretofore, the body or corrugated
part of such appliances were made of wood, paper, or hair.
According to this my said invention I employ in the construction of wrappers a
combination of iron or metallic holding frame and compressed seeds, or compressed
incal.
The backing of the wrapper is preferably of wire, iron, or steel or buffalo hide, its
borderings are of iron strips welded to each other or secured by means of rivets or
otherwiso secured, or of wood secured to the backing by pins.
The recessed inner space constituting the corrugated body of the wrapper is then filled
in with oil seeds, linseed meal, cotton meal, pollard combined or other like compressable
seed, or meal this is next compressed by means of a corrugated dio or pressing
piece, and the material so compressed and formed is then ready for the usual "facing
of tin or sheet metal. The seed or meal body of the wrapper as above described not
only forms a solid durable part of the wrapper (but it is also a non-conductor of heat)
and when worn or shaken can be removed from the framing and worked or ground up
along with other seeds or meal and is so further utilized.
The appliance for facilitating filling the bags, and forming the cako consists of an
oblong mouth piece, and holding piece for holding fully extended the mouth of the bag
and for suspending the same in the mould or box.
The mouth pieces I hinge or otherwise mount upon radius arms capable of being
revolved or they are mounted so as to have endwise or lateral movement thereby to
bring the several bags into position under the breech or discharge from the "kettle."
The mouth piece is of form and dimensions to nearly or about fit and fill the mouth of
the bag, the effect is to distend the bag and as the latter is suspended from hooks or
pins at opposite ends of the mouth piece, the bag is open from top to bottom so that
there are no folds or creases unoccupied by seed or meal which is free to drop to the
bottom of the bag, and to fill the same evenly and regularly to the required height
Such being the nature and object of this my Invention, the following is a complete
description of same, reference being had to the accompanying drawings.
Figs. 1 and 2 are plan view and section of the framing of the wrapper.
Figs. 3 and 4 are plan and edge view of the corrugated die for compressing tho
seed in the framing 1.
Fig. 5 is a front view of completo wrapper open.
Fig. 6 is a view of the back of the wrapper and Fig. 7 is the side or edge view
showing the seed bag enclosed.
Figs. 8 and 9 are plan and side view of the appliance for stretching or distending

page_text: Figs. 10 and 11 are front and side views of the bag and distender in position.
Fig. 12 is an elevation showing a part of the "kettle" and the axis and arms or
radial bearings which carry the mouth pieces and seed bags for filling.
Fig. 13 is a plan view of Fig. 12.
Fig. 14 is a vertical section of part of Figs. 12 and 13.
The remaining Figures are detached parts hereinafter referred to.
At 1 is a metal frame preferably welded at the angles or corners over which frame
is placed a thin sheet of soft steel, or buffalo hido which is forced into the frame 1 by
a die 2 forming a dish 3 which is filled with seed, or other like compressable seed or
meal, the latter then being compressed, consolidated, and corrugated by the application
of and pressure upon the die 2, thus forming one half of the complete wrapper shown
at Fig. 5.
The halves are joined and hinged in the ordinary way as at 4.
At 5 is the funnel or appliance employed for distending the bag 6-5 being placed
in the mouth of the bag 6 and the probe or pin 6* secures the bag in position as shown
at Fig. 10.
The bags and distending pieces are removed to the carrying boxes 7, and the lower
end of the bag passed through the mouth of the box and the funnel and the projecting
edge 8 of the funnel 5 rests upon the top of the box, the bag 9 hanging pendent as
shewn in Fig. 12, the bags are now moved on the axis 10 (see Fig. 13) so as to be
brought into the position of 9 under the kettle 11 whereon the attendant will press
down the treadle lever, (see Fig. 12), the opposite end 13 will lift or raise the frame 7
and bags 9 under the mouth of the kettle 11, whilst the connecting rod 14 will by the
lever 15 also raise the lietch or slide 16 of the kettle mouth so that the seed is free
to pass into and fill the bags, meanwhile the attendant will have been placing other
three empty bags and funnels into position as shewn at 17. The lever 18 will now
be pulled over on its fulcrum 19, its lower end 20 raising or permitting the lever 12
to move on its fulcrum 21, thus lowering the bags and closing the hetch, the
frames will now be moved a quarter of a circle on the axis 10, the full bags
contained in the frame 7 will by bearing upon and against the anti-friction runner 18
and the axis 19 coming in contact with 18* be tilted or moved on the axis 19 into
nearly the horizontal position as shown in Fig. 13, the bags are then ready for
withdrawal from the frame 7 and being placed in the wrappers ready for removal
to the press.
Having now particularly described and ascertained the nature of my said Invention,
and in what manner the same is to be performed, I declare that what I claim is;
Firstly A framo such as shown at Fig. 1, having a dish shaped lining of steel
or buffalo hide containing compressed and corrugated seed, all in combination and
constituting the improved wrapper as herein described and illustrated by the
annexed drawings.
Secondly The funnel or mouth piece 5, the holding and carrying frame 7
revolved by the radial appliance 10ª all in combination as herein described and
shown in the annexed drawings.
Lastly I claim the frame such as 7 connected with or rotating around or along
with an axis, and carrying the seed bags or cloths to be filled all in combination
and in connection with the "kettle."
