I 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:
For ordinary sized Envelope take paper 8 inches deep 5½ inches wide, cut
away from each corner slips inch wide 2 deep, which leaves, an inch margin
on either side for folding over to complete or form body of Envelope, and makes,
a top and bottom flap, the top flap is to be, covered inside with good gum, including
inch of inner part of back of Envelope, then the end of bottom Hap B, to
have inch border of gum C thickly applied inside, on the margins B also at the
central part, of Envelope as these margins B are after the gauze A is applied
folded over and after being stuck down form the body of the Envelope.
The invention chiefly consists in a strip of gauze A, like that used by milliners
which is of a gluey substancé and becomes perishable after coming in contact
with moisture, cut strips 3 inch wide on the cross, so that the thread in the
gauze A comes in a slanting direction across the orifice of the envelope.
The said gauze A being again cut at interviews of distances of inch apart
half way through the narrow way of strip of gauze A.
Moisten the gum C, already applied to the end inside of bottom flap to which

page_text: stick this strip of gauze A, leaving half of it half of it projecting over the edge
which gauze A will then meet the gum C opposite on the inside upper part of
outside flap on to which this other projecting part of gauze A is applied when
closing in the letter, and before sticking the the entire and top flap down.
The gauze A is cut to meet the end line of edge of the margins B and is
stuck down with them and secures the sides from invasion.
Figs. 1 and 2 represent
Fig. 1 the Envelope before folding
Fig. 2 after folding and ready for use.
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 :-
An Envelope with a piece of perishable gauze A cut on cross, and attached to
inner flap which gauze A when applied to opposite flap at the fold encloser the
letter which cannot then be taken out without destroying gauze A. A correct
drawing from the Patent Office (Fig. 1) refers to Envelope before being folded
(Fig. 2) after it is made and ready for use.
