COMPLETE SPECIFICATION.
An Envelope for the Protection of Letters from being Opened, or in
any wise Tampered with, without Immediate Detection.'
I, THOMAS HENRY COLLINS, of Saint Lawrence, Winchester, in the County
of Hampshire, Hairdresser, 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 relates to improvements in envelopes or wrappers, for enclosing
letters of correspondence, the object of which is to prevent the letter contained
therein from being tampered with by any person other than the addressee, or
person or persons for whom the same may be intended, without the fraud being
detected.
I attain this by perforating certain, or any part or parts, of the edges of said
envelope or wrapper, or, and serrating, fringing, scalloping, vandyking or otherwise
treating the edge or edges of the gummed flap, so as to render the same uneven or
irregular, in order to make it a matter of impossibility to open the said envelope
or wrapper, and peruse or extract any part of its contents, and again replace the
same without the said envelope shewing unmistakeable signs of having been
opened.
The same manner of perforating and serrating or the like may be adopted in the
manufacture of private or business memorandums or other papers or similar self
contained documents, the said serrating or the like being for the prevention of the
same being opened for the purpose of altering the wording or figures therein in
pursuit of mischief or fraud, while the perforated edge permits the same being
opened thereat by the addressee, in order that the said memorandum or other
document may assume a rectangular or regular shape for filing and other purposes..
In the accompanying drawings
Fig. 1 is a view of an ordinary commercial envelope prepared according to my
invention, the gummed flap of which has been both serrated or scalloped and
perforated.
Fig. 2 is a view of a folded memorandum form, with perforated edge and flap as.
described.
I wish it understood that I may make the said envelopes of any desired shape or
size, of any suitable material, with any or all of the edges A, B, C, D when folded
as at Fig. 1, perforated as at E Fig. 2, with or without perforating and serrating or-
the like, the Hap F, as at Figs. 1 and 2, or may perforate or serrate or both the
flap F without perforating the edges, or both as may be desired.
