IMPROVEMENTS IN THE MANUFACTURE OF ENVELOPES
Year: 1867

page_text: LETTERS PATENT to Edward Hely, of Seventeen, Lower Ormond Quay,
in the City of Dublin, Envelope Manufacturer, for the Invention of
"IMPROVEMENTS IN THE MANUFACTURE OF ENVELOPES."
Sealed the 20th August 1867, and dated the 26th February 1867.
PROVISIONAL SPECIFICATION
left by the said Edward Hely at the
Office of the Commissioners of Patents, with his Petition, on the
26th February 1867.
I, EDWARD HELY, of Seventeen, Lower Ormond Quay, in the City of Dublin,
Envelope Manufacturer, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN THE MANUFACTURE OF ENVELOPE." to be as follows;-
This Invention consists of an envelope so formed that the use of gum or
other matter of that nature on the outer paper forming the envelope upon
which it is usually placed is entirely dispensed with, and in place of using a
gummed flap in the usual way a piece of gummed paper or other gumined
material is placed under the flaps or folds of the envelope.
This paper or
other material is of or about the full size of the envelope when folded, and the
three flaps of the envelope usually closed down are at once fastened to it,
leaving the fourth flap to be closed by the party using the envelope.
The principal advantages of the Invention are these, 1st, the envelope is
what is known as a "high flap" or bankers' envelope; 2ndly, a considerable
saving of paper of which the ordinary envelope is made is effected by dis-
[Price 8d.]

page_text: pensing with any overlapping of the edges (save, if desired, the slightest for
mere appearance sake); 3rdly, the joining will be more perfect and secure
than in the ordinary envelope, as the entire of the back flaps (except the
trifling overlap, if used,) will be fastened to the under gum paper throughout;
4thly, wetting the gum or other adhesive matter used in envelopes (usually so
deleterious to health) will be entirely unnecessary, because it is the ungummed
flap that may be and is intended to be wet in order to be attached or fastened
to the gum paper underneath, as described; 5thly, while a more secure
envelope will be produced a considerable saving in expense may be effected.
SPECIFICATION in pursuance of the conditions of the Letters Paient,
filed by the said Edward Hely in the Great Seal Patent Office on the
26th August 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
ПELY, of 17, Lower Ormond Quay, in the City of Dublin. Envelope Manu-
facturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-sixth day of February, in the year of our
Lord One thousand eight hundred and sixty-seven, in the thirtieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Edward Hely, Her special license that I, the said Edward Hely, my
executors, administrators, and assigns, or such others as I, the said Edward
Hely, my executors, administrators, or assigns, should at any time agree
with, and no others. from time to time and at all times thereafter during
the term therein expressed, should and lawfully might make, use, exercise,
and vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN THE
MANUFACTURE OF ENVELOPES," upon the condition (amongst others) that I,
the said Edward Hely, my executors or administrators, by an instrument in
writing under my hand and seal, should particularly describe and ascertain
the nature of the said Invention, and in what manner the same was to be
performed, and cause the same to be filed in the Great Seal Patent Office
within six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE. that I, the said Edward Hely, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following

page_text: statement, reference being had to the accompanying Sheet of Drawings, and
to the letters and figures marked thereon, that is to say:
My said Invention consists of an envelope so formed that the use of gum or
any substitute therefor or other matter of mucilaginous or adhesive nature on
the outer paper or flap forming the envelope upon which it is usually placed
is entirely dispensed with, and in place of using a gummed flap in the usual
way a piece of gummed paper or other gummed material is placed under the
flap or folds of the envelope. This piece of gummed paper or other mucila-
ginous or adhesive material is, by preference, of about the full size of the
envelope when folded, and the three flaps of the envelope usually closed down
are at once fastened to it, leaving the fourth or loose flap to be closed by the
party using the envelope. This is done by moistening the ungummed flap
and pressing it down in a moistened state upon the gummed surface of the
paper prepared so as to adhere to it.
And in order that my said Invention may be fully understood I shall now
proceed more particularly to describe the same, and for that purpose shall refer
to the annexed Sheet of Drawings, the same letters of reference indicating
corresponding parts in both the Figures.
Figure represents an open. envelope constructed according to my Invention.
A, A, A, are the 3 fixed laps or folds which are secured down upon the piece
of gummed paper or other suitable material B inserted inside the envelope, or
under the laps or folds A with its gummed sides outwards. By means of
securing the laps or folds A the necessity for any overlapping of their edges is
avoided as they may be made so as only just to meet, as shown at C, C, in
the Drawing, or only to overlap to a very slight extent for the sake of neat-
ness, and hence a saving in the paper from which the blanks are or originally
cut out is effected. The upper portion of the gummed surface of the paper B
(colored pink in the Drawing) which remains exposed after the laps A have
been folded down and secured in their places serves to secure the loose flap D,
which according to my Invention is entirely devoid of gum or other adhesive
material. In closing the envelope it is simply requisite to moisten the un-
gummed flap D, and hence no deleterious effects from the gum or other
adhesive material employed can possibly result. Envelopes constructed in the
manner herein-before described and shown also combine the advantages of
what are known in the trade as "high flap" or bankers' envelopes. The
securing of the several flaps will be more effectual, and considerable economy
in production will be effected.
In some cases in connexion with the ungummed loose flap a prepared
gummed surface, such as is shewn in Figure 2, colored pink, may be

page_text: employed. A, A. A¹, are the usual fixed flaps cemented together at their
overlapping edges, as shown by the dotted lines, and instead of the gum or
other adhesive material for closing the envelope being applied to the inside of
the loose flap D, which has heretofore been the practice in the manufacture of
adhesive envelopes, I make the loose flap devoid of gum or adhesive material,
and place the gum or other adhesive material intended for securing the loose
flap upon a portion of the fixed flap A', as shown at B, colored pink, or upon
a portion of the three flaps A, A, A', or upon the adjoining extremities E, E,
of the two flaps A, A, only, in which case the envelope will have to be dif-
ferently folded, that is to say, the flaps A, A, will be folded on the top of the
flap A in lieu of underneath it, and the ends of the two flaps A, A, should be
made to meet at B.
Having now described and particularly ascertained the nature of my said
Invention, and the manner in which the same is or may be used or carried
into effect, would observe in conclusion that what I consider to be novel and
original, and therefore claim as the Invention secured to me by the herein-
before in part. recited Letters Patent is, the method herein-before described of
forming and securing envelopes, by means of which the use of adhesive material
fixed on the outer flap is dispensed with.
Jn. witness whereof, 1, the said Edward Hely, have to this my Speci
fication, set my hand and seal, the Twenty-third day of August, One
thousand eight hundred and sixty-seven.
