and Letter Sheets, and the like.
L. GEORGE FREDERICK REDFERN, of the firm of G. F. Redfern & Co., the General
Patent Office, No. 4, South Street, Finsbury, in the County of Middlesex, Patent
Agents, do hereby declare the nature of this invention (a communication from abroad
by Walter R. Binns, of Bebek, near Constantinople, in the Sultanate of Turkey) to be
as follows:-
My invention relates to envelopes, postal wrappers, combined envelope and letter
sheets, and the like.
According to my said invention provide a trip of paper or other suitable
material which can be folded two, three, or more times according as to whether it is
desired to produce an envelope or wrapper or a combined envelope or letter sheet, or
the like of greater or less size.
One end of the said strip is in the form of a flap, and is gummed or otherwiso
treated or constructed so that it can be secured.
The edges of the sheet are goffred, frilled, furled, or fluted, so that when the said
sheet is folded the goffres. frills, furls or flutes form a protection against intrusion and
serve to prevent other postal mauer from slipping between the folds.
In some cases I make the envelopes or the like with wings at the sides and bottom,
the said wings being always goffred or fluted as above described.

page_text: I, GEORGE FREDERICK REDFERN, of the firm of G. F. Redfern & Co., the General
Patent Office, No. 4, South Street, Finsbury, in the county of Middlesex, Patent
Agents, do hereby declare the nature of this invention (a communication from abroad.
by Walter R. Binns, of Bebek, near Constantinople, in the Sultanate of Turkey) and
in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
My invention relates to envelopes, postal wrappers, combined envelope and letter
sheets and the like.
According to my said invention I provide a strip of paper or other suitable material
which can be folded two, three or more times according as to whether it is desired to
• produce an envelope or wrapper, or a combined envelope or letter sheet or the like of
greater or less size.
One end of the said strip is in the form of a flap and is gummed or otherwise
treated or constructed so that it can be secured.
The edges of the sheet are goffred, frilled furled or fluted.
To enable my invention to be fully understood I will describe the same with
reference to the accompanying drawing, in which,
Figure 1 is a view of a combined envelope and letter sheet in its open position.
Figure 2 shows the same closed, and,
Figure 3 is a section on the line x, x Figure 2.
a is a strip of stout or. stiff paper, one end of which is gummed or otherwise
treated to enable the envelope to be closed. As shown the said strip, below the flap b,
is only adapted to fold once at c, but it is to be understood that it may be made of any
required length and folded at two or more places as desired. Also, in some cases,
when a large sheet is required, flaps d, d which are turned inwards when the sheet is
folded can be formed at the sides of the sheet as indicated by dotted lines in
Figure 1.
e, e are goffres or corrugations which are formed at the lateral edges of the sheet
and which, when the sheet is folded, lie one within the other, as shown in Figure 3.
The advantage of the said goffres or corrugations is that they serve to prevent letters
or other postal matter from slipping between the folds of the sheet and also form a
protection against intrusion.
The said goffres or corrugations may be formed.in any suitable manner, for instance
by passing the parts to be acted upon between fluted rollers or by placing them
in a press.

page_text: 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
:-
(1) An envelope, postal wrapper or the like, the open ends or sides of which are
goffred, fluted or corrugated, substantially in the manner herein before described for
the purpose specified.
(2) The manufacture and use of the improved envelopes, postal wrappers or the
like, substantially as herein before described and illustrated in the accompanying
drawing.
