"
HIPPOLYTE PLANCHE, one of the Firm of Planche Brothers, in the Republic of
France, City of Paris, 5, Rue Mazagran, Paper Manufacturers. CLOSING OF BAGS
OF PAPER, LINEN, OR OTHER MATERIAL."
The object of this Invention is to produce a bag for the conveyance by post of
samples of grain, seeds, or other substances in which the mouth of the bag may be
securely closed without the use of gum or other adhesive substance, and from
which the contents cannot escape, and the Invention consists in a peculiar mode of
folding the paper or other material of which the bag is formed.
The sheet of paper or other material which must be of a rectangular shape and
is folded by two parallel creases into three parts, two parts being of equal width,
and the third part about half the width. A strip is cut off the bottom from the
two side flaps, leaving a portion of the centre part to form a flap with which to
close the bottom of the bag.
A short distance below the top of the paper the smaller or left hand flap is cut
straight across, so that when this flap is folded over a square ear will be left
projecting from the left hand side of the centre part. The top angle of the
shortened side flap is then turned down and the projecting ear is also turned
down.
The blank for the bag having been thus prepared it is made up in the following
manner, viz., the right hand or larger side flap is first folded down, and the left
hand or smaller side flap is then folded over it and attached by guin or paste, and
the bottom flap is turned up and secured over the side flaps.

page_text: The bag thus formed is ready to be closed, which is effected by turning down the
top of the bag diagonally from right to left so as to form a right angled triangle,
-and-inserting the apex-of-the-triangle-under-the-left-hand-flap. This triangle-is
then folded in half, and the projecting ear before mentioned is brought into a
-position where it can-be-inserted-in its triangular form under the first folded
triangle
The mouth of the bag is thus securely closed. In this mode of folding there
will be certain superfluous portions of the paper which may be cut away to tighten
the bag, one such portion being at the top of the right hand flap, another being a
portion of the projecting ear, and a third the folded over angle of the left hand or
smaller side flap.

HIPPOLYTE PLANCHE, one of the Firm of Planche Brothers, in the Republic of
France, City of Paris, 5, Rue Mazagran, Paper Manufacturers. CLOSING OF BAGS
OF PAPER, LINEN, OR OTHER MATERIAL."
The object of this Invention is to produce a bag for the conveyance by post of
samples of grain, seeds, or other substances, the mouth of which may be securely
closed without the use of gum or other adhesive substance, or of a metallic or other
fastener, and the Invention consists in a peculiar mode of folding the open end of
the paper or other bag so that the contents shall not escape therefrom.
In carrying out my Invention I prefer to use a bag specially formed for the
purpose, and I prepare the material of which the bag is to be made according to
one of the forms shewn at Figures 1, 2, 3, 4, and 5 in the accompanying Drawing.
In these Figures the sheet of paper or other material of which the bag is to be
made must be of a rectangular shape and preferably of greater length than, breadth.
The material is folded by two longitudinal parallel creases 1, 2, and 3, 4, into
three parts, two parts being of equal width, and the third part about half the
width. A strip is cut the bottom from the two side flaps leaving a portion of
the centre part to form a flap A, see Fig. 1, with which to close the bottom of the
bag, or the bottom of the bag may be closed by pasting or otherwise securing
together when folded the parts. A¹, B'. In this case a flat portion will be presented
on which the postage and other stamps may be placed.
The top of the smaller or left hand flap is cut straight across on the line D, E,
Fig. 1, so that when this flap is folded over a square ear will be left projecting
from the left hand side of the centre part, see Fig. 2. The top angle of the
shortened side flap is then turned down or it may be removed so as to leave the
triangular space L. The angle C¹ of the projecting ear is also turned down on the
line D, F, Fig. 2, or it may be removed as at C, Fig. 1.
The top of the right hand flap may also be removed on the line G, H, Fig. 2, or
it may be cut off as shewn at Figures 3 and 4, and all the external angles or
points may be rounded off. By removing these superfluous portions or angles
the weight of the bags will be reduced.
The form shewn at Fig. 4 is not suitable for the conveyance of samples of seeds
or substances of a granular nature, but it can be used for samples of a certain size
or for legal or other papers.
The blank for the bag having been thus prepared, it is made up in the following
manner, viz. -The right hand or larger side flap is first folded down so as to
make the edge to correspond with the line p', p², see Fig. 6, and the left hand or
smaller side flap p', 8, 8¹, p², is then folded over it and attached thereto by gum or
paste along the edges 8, 8¹, p². The bottom is then completed by turning up the
flap A and securing it over the side flaps by gum or paste, see Fig. 7, and the bag
is ready for use.
The bag thus formed is ready to be closed. This is effected by turning down
the top of the bag from right to left on the line p, y, Fig. 7, so as to form a right
angled triangle p, v, y, the apex of which is inserted under the part p³, 8, of the
left hand flap, which part has been left ungummed for the purpose (see Fig. 8).
This triangle p, v, y, is then folded in half on the line v, z, Fig. 8, and the pro-
tecting ear p, m, p¹, is brought into a position (see Fig. 9) where it can be inserted in
its triangular form, having been first folded on the line p, p, under the part s, y, of
the first folded triangle, and a bag will be formed having a triangular shaped top v, z, p,
as shewn at Fig. 10. The mouth of the bag is thus securely closed, and when the
blank is prepared in either of the forms shewn at Figures 1, 2, or 3, the point of

page_text: the triangular shaped top v, z, p, will be below the upper edges of the larger side
flaps shewn in dotted lines t, w, (Fig. 8), and the bag will be doubly folded at
that point; thus the escape of the contents when of a granular nature will be
_effectually prevented.
In order to strengthen the part 8 a piece of paper or other material is attached
-by-gum-or-paste, see Fig. 5.
Figures-11 and 12 show. respectively a transverse sectional elevation and a front
elevation of a bag filled with grain and made with a flat portion q, q', at the
bottom to receive-the-postage-and-office-stamps. TP and Th, Fig. 13, represents_in
section another mode of making the flat portion; a, a², and a¹, a², are separate
pieces of paper or one piece folded and secured to the bottom O of the bag by gum
or paste; Fig. 14 shows a third mode of producing the flat portion.
In this Figure n, n², and n¹, n², are the sides of the bag, and N is separate
bottom which is secured inside the bag as shewn by gum or paste.
"
Having now described the nature of my Invention for Closing of Bags of
Paper, Linen, or other Material," and explained the manner of carrying the same
into effect, I wish it to be understood that under the above in part recited Letters
Patent I claim,-The mode of closing and securing the mouths of paper and other
bags for the conveyance of samples or papers and documents by post without
the use of adhesive material or metallic or other fasteners, as herein shewn and
described.
In witness whereof, I, the said Hippolyte Planche, have hereunto set my hand
and seal, the Nineteenth day of January, in the year of our Lord One
thousand eight hundred and eighty.
