IMPROVEMENTS IN FASTENING THE MOUTHS OF ENVELOPES OR PAPER BAGS
Year: 1884

page_text: I, DAVID DALZIEL, of No G, Battlefield Crescent, Langside in the County of
Renfrew, North Britain, Wholesale Stationer do hereby declare the nature of
the said invention for IMPROVEMENTS IN FASTENING THE MOUTHS OF ENVELOPES
OR PAPER BAGS to be as follows:-
This Invention, which relates to improvements in fastening the mouths of
Envelopes or Paper Bags, is applicable to that class of envelopes used for the
transmission of samples of grain or other produce, and consists in forming the said
envelope or bag with an opening along one edge thereof, extending from the mouth
or open end downwards towards the closed end of the said envelope or bag. Upon
the front portion of this envelope or bag is a flap whose outer angle is or may be
of ninety degrees or thereabouts. This flap extends outwards at the side and at
the part where the opening is formed.
Assuming the envelope or bag to be laid front downwards and the opening and
flap to be at the right hand side thereof, in closing the said envelope or bag, it is
doubled from its top right hand corner diagonally across at or about an angle of
forty five degrees, so that the top left hand corner is over the lower termination of
the side opening. The envelope or bag is then doubled over in the reverse
direction thereby forming, at the top of it, an angle of about ninety degrees, whilo
the flap is point downwards. The flap is then turned in under the four thicknesses
of paper or other material of which the Envelope or bag is composed, and thereby
closes the mouth thereof and prevents any of its contents from falling, or being
shaken, out.
COMPLETE SPECIFICATION.
I, DAVID DALZIEL, of N° 6 Battlefield Crescent, Langside in the County of
Renfrew, North Britain, Wholesale Stationer do hereby declare the nature of
my invention for IMPROVEMENTS IN FASTENING THE MOUTHS OF ENVELOPES OR
PAPER BAGS and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :—
My Invention, which relates to Improvements in fastening the mouths of
Envelopes or Paper Bags, is applicable to that class of Envelopes used for the
Print

page_text: transmission of Samples of grain or other produce, and consists in forming the said
envelope or bag with an opening along one edge thereof, extending from the mouth
or open end downwards towards the closed end of the said envelope or bag. Upon
the front portion of this envelope or bag is a flap whose outer angle is or may be
of ninety degrees or thereabouts. This flap extends outwards at the side and at
the part where the opening is formed.
In order that my said Invention may be properly understood and readily carried
into effect I will now describe the drawings hereunto annexed.
Figure 1, represents the form of a piece of paper or other material from which
an envelope or bag is, or may be made according to my present Invention.
Figures 2, and 3, represent the same in progressive stages towards the completed
envelope or bag represented at Figure 4.
Figures 5, and 6, represent the progressive stages towards closing the mouth of
such envelope or bag, and
Figure 7, represents such an envelope or bag when so closed, a portion only of
which envelope or bag is represented at the three last described Figures.
In forming an envelope or bag according to my present Invention, a piece of
aper or other material of the form represented at Figure 1, is stamped or cut
out. The material is doubled over at the dotted line a, in which form the said
material is represented at Figure 2.-The material is then doubled over at the
dotted line b, (Figure 1,) and then at the dotted line c, in each of which stages the
envelope or bag is represented respectively at Figures 3, and 4.-The parts d, and e,
are secured down by gum, paste or other mucilage upon the part marked f. and the
envelope or bag is complete.
For closing the mouth of an envelope formed in the manner hereinbefore
described and shewn at Figure 4, the upper or open end is doubled over at the
dotted line g, (Figure 4,) in which condition the said envelope or bag is represented
at Figure 5.-The said envelope or bag is then doubled over at the dotted line h,
(Figure 5,) into the position shewn at Figure 6, wherein the flap i, of a single
thickness of material is turned with the point downwards.-This flap i, whose
outer angle is preferably of less than ninety degrees is then turned in under the
four thicknesses of paper or other material already doubled down as bereinbefore
set forth. In this condition the mouth of the said envelope or bag is closed, as
is represented at Figure 7, of the annexed drawings.
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
The improvements in fastening the mouths of Envelopes or paper Bags by means
of the flap i, doubled or folded in the manner substantially as hereinbéfore set
forth with reference to the annexed drawings.
