Complete Specification Accepted, 3rd Aug., 1898
I, JOHN SANDS GALBRAITH of Glasgow, in the County of Lanark, North Britain,
Writer, do hereby declare the nature of this invention to be as follows:
This Invention which relates to improvements in envelopes has for its object to
render the surreptitious opening of envelopes more difficult, to give greater security,
besides having always one side of the envelope of a smooth or even surface and
unencumbered which could be utilized as a means of advertising or otherwise, whilst
the other side would be retained for the address, as well as for the special affixing
of the postage stamp serving as a greater hindrance to the opening of the envelope by
persons unauthorized or having fraudulent intentions.
The Invention consists in making the envelope of paper or other suitable material
with an extension or flap at one end of the piece of the character hereinafter
described to close or seal the envelope, and with two narrow strips one at each side
of the piece extending the length of the envelope leaving the under part of the piece
to be doubled over laid upon or secured to the strips above referred to.
The envelope after being cut or shaped for use, the side strips are folded over, on
the top of which the under piece is also doubled over lengthwise, and its edges caused
to adhere to the side strips parallel or nearly so with the outer edges of the same, thus
giving a strong substantial envelope.
The flap for closing or sealing the Envelope is broader at one end than the other,
being cut at an angle, or tapered to a point touching or almost so the one corner of
the envelope, whilst the broad end is also slightly tapered forming a pointed flap-
which may be rounded if desired, the object and intention being, that in Envelopes
posted the stamp should be affixed on and overlapping the point or edges of the flap
at the broad end thereof, which will, at the same time, serve to seal and close the
Envelope.
If desired the flaps could be gummed in the ordinary way, which in addition to the
closing of the letter by the attachment of the stamp in the manner described, would
act as a greater security against the opening of the envelope.
The Envelope when used, but not passed through the Post Office would have the
flap gummed in the ordinary way.
Dated this 29th day of September 1887.

Improvements in Envelopes.
I, JOHN SANDS GALBRAITH of Glasgow in the County of Lanark, North Britain,
Writer 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:-
This Invention which relates to Improvements in Envelopes has for its object to
render the surreptitious opening of Envelopes more difficult, to give a greater
security, besides having always one side of the Envelope of a smooth or even surface
and unencumbered which would be utilized as a means of advertising or otherwise,
whilst the other side would be. retained for the address as well as for the special
affixing of the postage stamp, serving as a greater.hindrance to the opening of the
Envelope by persons unauthorized or having fraudulent intentions.
The Invention consists in making the Envelope of paper or other suitable material
with an extension or flap at one end of the piece, of the character hereinafter
described to close or seal the Envelope, and with two narrow strips one at each side
of the piece extending the length of the envelope leaving the under part of the piece
to be doubled over, laid upon or secured to the strips above referred to.
The Envelope after being cut or shaped for use, the side strips are folded over, on
the top of which the under piece is also doubled over lengthwise, and its edges caused
to adhere to the side strips parallel or nearly so with the outer edges of the same,
thus giving a strong, substantial Envelope.
The flap for closing or sealing the Envelope, is broader at one end than the other,
being cut at an angle or tapered to a point, touching or almost so, the one corner of
the envelope, whilst the broad end is also slightly tapered, forming a pointed flap
which may be rounded if desired, the object and intention being, that in envelopes
posted the stamp should be affixed on and overlapping the point or edges of the
flap at the broad end thereof, which will at the. same time serve to seal and close
the Envelope.
If desired the flaps could be gummed in the ordinary way which in addition to
the closing of the letter, by the attachment of the stamp, in the manner described
would act as a greater security against the opening of the envelope.
The Envelope when used, but not passed through the Post Office would have
the flap gummed in the ordinary way.
In order that my said Invention may be most fully understood and readily
carried into effect I will now proceed to describe the drawings hereunto annexed.
Figure 1 is the envelope (constructed according to and constituting my present
invention) developed or the open sheet of paper before folding Figure 2 represents
the envelope closed.
My present improvements consist in shaping the paper of which the envelope is
to be made in the manner shewn in Figure 1 wherein the shaded portions A are
gummed. To form the envelope the side flaps B, are folded inwards on the dotted
lines, O D, and E F. The flap, G, is then folded on the dotted line (E, over the

page_text: side flaps B adhering to the same by the gummed portions A and making the line H I
to coincide with the dotted line D F. Lastly the Hap K is folded over and fastened
by the gummed portions A, to the before mentioned flap G. If the envelope is to
be posted the stamp is affixed on or over the edges of the flap K, as represented at
Figure 2 thus making the envelope doubly secure.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed I declare that what I
claim is
The manufacture of Envelopes from paper or other suitable material, stamped or
cut out substantially as described with reference to the annexed drawings.
