PROVISIONAL SPECIFICATION.
Improvements in Envelopes.
I, FERDINAND BOSSHARDT, of the Firm of F. Bosshardt & Co., of
4, Corporation Street, Manchester, in the County of Lancaster, Patent Agent, do
hereby declare the nature of this invention which has been communicated to me
from abroad by Jean Joseph Moisset, of Canssade, (Tarn and Garonne), in the
Republic of France, Architect, to be as follows:-
The object of this invention is to provide an envelope which may close completely
or only partly and can be readily and neatly opened without the use of an
instrument.
To this end I furnish or form the flap of the envelope near the fold, with a band,
about five to six millimetres wide, the resistance of which is at least twice as
large as that of the paper of the envelope along the two sides of the same.
The application of this principal may be easily carried out in two different
manners, viz.
In increasing the resistance of the paper of the envelope in the width of the
said band; or diminishing the resistance of this paper on the two sides of this
band.
In the first case, it is sufficient to double this band of paper, fabric, or other
material and render it stronger.
In the second case, the envelope along the two sides of this band may be scored
or the said band attached to the envelope by a chemical agent which diminishes
the resistance of the latter. Or the two means may be employed simultaneously,
by manufacturing a specially pressed paper, which provides a band thicker than
the paper of the envelope along the two sides thereof.
Dated this 7th day of December 1892.

COMPLETE SPECIFICATION.
Improvements in Envelopes.
I, FERDINAND BOSSHARDT, of the Firm of F. Bosshardt & Co., of 4, Corporation
Street, Manchester, in the County of Lancaster, Patent Agent, do hereby declare
the nature of this invention, which has been communicated to me from abroad by
Jean Joseph Moisset, of Canssade, (Tarn and Garonne), in the Republic of France,
Architect, 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 this invention is to provide an envelope which may close completely
or only partly and can be readily and neatly opened without the use of an
instrument.
Envelopes for letters and the like now in use cannot be closed entirely owing to
a third of the flap not being gumed which causes the contents of being often
examined without leaving any trace externally, besides it is difficult to open the
same without becoming impatient when not having a sharp instrument at disposal,
which latter in opening the envelope is also liable to cut its contents.
And in order that my invention may be more fully understood I have caused to
be appended hereunto one sheet of drawings showing an elevation of my improved
envelone

page_text: .
In carrying out my invention 1 furnish or form the flap of the envelope near the
fold, with a band a, b, about five to six millimeters wide, the resistance of which is
at least twice as large as that of the paper of the envelope along the two sides of
the same.
The application of this principal may be easily carried out in two different
manners, viz.:
.
In increasing the resistance of the paper of the envelope in the width of the
band a, b, or diminishing the resistance of this paper on the two sides of this
band.
In the first case, it is sufficient to double this band of stronger paper, fabric, or
other material.
In the second case the envelope along the two sides of the band may be scored
or perforated.
The means described may be employed in connection with paper specially
pressed in the manufacture to provide a band thicker than the paper of the
envelope along the two sides thereof.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I declare that what I
claim, is-
"In envelopes."
1st. A band a, b, of paper or fabric of any kind along the fold of the flap of the
envelope, substantially as and for the purpose set forth.
2nd. Scoring the envelope on both sides of the band a, b, substantially as and for
the purpose set forth.
Dated this 11th day of August 1893.
