Improvements in or Connected with Combined Envelopes and Letter
Sheets for Correspondence and Advertisement Purposes.
I WILLIAM LAKE of Banbury, Oxfordshire Merchant do hereby declare the nature
of this invention to be as follows:-
This invention relates to note or other paper so constructed and arranged as to
answer the purpose for correspondence, at the same time forming an envelope giving
perfect privacy to the correspondence, or written contents and affording places in the
folds for the purpose of advertisements which also are enclosed when the paper is
folded and the envelope formed, this I accomplish without the waste of paper, which
generally takes place in combinations of this sort, by my method the paper and folds
are so arranged that the advertisements, can be all printed at one time without the
necessity of reversing the paper, the paper is cut, so as to form six or more square
folds three in breadth the envelope part is attached to the upper side of the centre
square, in folding the paper the three lower squares are folded over the three upper
squares the two ends folding inwards forming together one square after which the
attached envelope is folded round same giving an appearance of an ordinary letter.

1 WILLIAM LAKE of 29 High Street, Banbury Oxfordshire, (Tradesman,) 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 :-
My Invention consists of cutting and making combined Envelopes and Letter Sheets
Both for commercial and private correspondence, and for advertisement purposes, by
providing two flaps only (instead of the customary three or four) either by cutting
the flaps as a part of the letter sheets or separately and attaching them by gumming
them to the letter sheets and of folding the same in the manner ascertained and set
forth in and by the following description and Drawings sent herewith.
In the accompanying Drawings I have shown the manner of carrying out my
Invention.
In some cases I place the two flaps at the top of the letter sheet as in fig. 1, whilst
I can vary the positions and sizes of the flaps and place one at top and one at side as
in figs. 2, 3 and 4.
I prefer cutting the envelopes and letter sheets all in one piece but I can cut either
or both flaps separate and attach them with adhesive as shown in fig. 9, where the
flap A is cut separate and attached by gumming.
I prefer the paper 3 fold, (but there is no restriction as to the number of folds) and
the top flap or flaps to be attached to or cut on the left hand fold as in figs. 2, 3, 4
and 5, but may be a continuation of either fold of paper. The position of the other
or side flap may be placed in various positions as shown on figs. 2, 3, 4 and 9.
When I vary the position of the flaps I vary the manner of folding the letter sheet.
In figs. 1 and 2 I fold the paper in a, b; then in c, d; so that a, b, lie on g, h, as
shown on figs. 1 and 2, and then upwards into the envelope: when it can be adapted
to meet the requirements of the half penny post for printed matter, invoices, &c., by
simply tucking the flaps in the side folds without gumming or sticking them; but
for written matter of the nature of correspondence, &c., I fold the flaps outside in the
usual manner as shown on fig. 7, and close them with gum or other adhesive.
When I provide a large top flap as in figs. 3 and 4 I fold the paper first in a, b,
so that k, k, meet c, d, and then upwards in h, i, so that h, b, lie on g, a, and then a, f
over on to g, e.
If I cut one of the flaps separately and attach it in the manner shown on fig. 9,
I fold the letter sheet as follows, into three equal divisions upwards in a, b, so that k, k,
meet c, d, and again in c, d, so that a, b, meet g, h. I then form the envelope by
folding the two sides h, k, and g, k, so that they meet in the centre of the face of the
envelope; I then close the two flaps A. and B when the envelope has the appearance
of fig. 7.

page_text: In figs. 6, 7, and 8 I show the envelopes closed according as I vary the position
and size of the flap or flaps, and whether I fold them inside as in fig. 5 or outside as
in fig. 6.
I use the inside of the two right hand folds for correspondence, Invoices Memo-
randum purposes or circulars or programmes &c., and the back of those folds for
advertisements when desired.
Having now particularly described and ascertained the nature of my Invention
and in what manner the same is to be performed, I declare that what I claim is,
1st. That with the aid of two flaps placed in certain variable positions and by
ingeniously folding the letter sheets to suit the size of the envelope which I purpose
making, I provide a simple and easily folded combined envelope and letter sheet, at
the same time affording complete protection to the correspondence or other matter,
whilst giving ample space for advertisement purposes if so utilised.
2nd. A combined envelope and letter sheet consisting of two or more folds of paper
and of two flaps A and B either placed at top or one at top and the other at one side
of the letter sheet as shown in Drawings.
3rd. A more convenient size and shape and more readily folded than any yet
produced at the same time as well adapted for commercial purposes as for private
correspondence.
