Specification Accepted, 20th July, 1888
I WILLIAM HUMPHREY WHEATLEY, of 156 Strand, in the County of Middlesex,
Patent Agent, 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
The object of the invention is to produce a cheap envelope in which the enclosure
shall be more safely kept, than it can be in an ordinary envelope, and consists in the
details of combination and construction, substantially as illustrated in the drawings,
hereinafter described and eventually pointed out in the claim.
Figure 1, illustrates the form in which a piece of paper is cut to form my newly
invented envelope
Figure 2, illustrates the same when folded.
Figure 3, illustrates the form of a modification of my envelope with the sealing flap
open.
Figure 4, illustrates the same sealed up.
Figure 5, is a sectional view of the same, taken on the line y z of Figure 4.
A piece of paper of any proper quality and thickness is cut of the form represented
in Figure 1. A, and A' being respectively formed for the front and back of the
envelope, B and B being the side flaps, and C the sealing flap The paper is then
first folded on the line between the parts A and A', so that these two parts A, and A¹
come together. The side flaps B, and B, are then folded over the two opposite
sides of A where they may be secured with gum or paste, or any other like adhesive
material The envelope is now ready for its enclosure, when this is put in, the
sealing flap C, which may be gummed is folded down over A¹, and sealed to, so that
the whole envelope presents the appearance illustrated in Figure 2. This envelope
may be used to transmit valuable letters and the like through the mail, and to that
end should be made of stout paper.

page_text: For money orders, and other similarly valuable packages, I have devised the
envelope represented in Figures 3, 4, and 5. This is a modification of the envelope
herein before described in this, that to the part A¹, is added the flap A", and to the
part A is added the extension D, having the flaps B¹ and B₁ and sealing flap C".
When the parts have been folded and secured in the relative positions represented
in Figure 3, the envelope is ready for its enclosure. When the enclosure is put in,
the extension D, is folded down over the part A¹, and the flaps B¹ B and C folded
down, and secured with gum or paste upon the edge of the part A, as illustrated in
Figs. 4 and 5.
These envelopes may either one of them, be opened by cutting through either
of the edges, so as to get at the enclosure.
Having now fully described and ascertained what the nature of my said invention
is, and how the same is made and performed, I do hereby declare that what I claim as
my invention, and desire to secure by Letters Patent.
1. An envelope comprising the parts A and A' side flaps B, and B, and the sealing
flap C, all folded, arranged and used, substantially as and for the purpose set
forth.
2. An envelope comprising the parts A, A', the extension D, and the flaps A", BB,
B B and C all formed, arranged and used substantially as and for the purpose
set forth.
