IMPROVEMENTS IN THE MANUFACTURE OF ADHESIVE SEALS
Year: 1875

page_text: LETTERS PATENT to Henry Kleinau, of King William Street, Strand,
in the County of Middlesex, for the Invention of "IMPROVEMENTS IN
THE MANUFACTURE OF ADHESIVE SEALS."-A communication from abroad
PROVISIONAL SPECIFICATION left by the said Henry Kleinau at the
Office of the Commissioners of Patents, with his Petition, on the
12th November 1875.
I, HENRY KLEINAU, of King William Street, Strand, in the County
of Middlesex, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN THE MANUFACTURE OF ADHESIVE SEALS," to be as
follows:-
The chief object of this Invention is to remedy the inconveniences
hitherto attendant on the use of preparations of wax and equivalent
materials in the sealing of letters and parcels.
Instead of preparing the sealing wax in sticks, as heretofore, and
igniting the wax to effect a deposit on the paper suitable for the pro-

page_text: duction of a scal, it is proposed to manufacture the composition in the
form of thick wafers of any desired shape, say, that of a disc, lozenge,
or oval, and to emboss on the same when desired a monogram or
device.
In applying this article as a seal to a letter it will only be necessary,
by the aid of a clip, to present its under side to the heat of a burning
taper, and while still soft to press it gently on the letter. When
however the sealing wax disc is prepared without a device the softening
of it by the taper heat will enable it to receive the pressure of an office
stamp or signet ring, as ordinarily applied in the sealing of documents.
The seals may be prepared in various ways, but that preferred is to
pass a thin tissue, say, of paper through a bath of the wax, composition,
or equivalent material, and thereby to obtain a deposit or coating of the
composition on both sides of the tissue. From the adhesive sheet thus
prepared discs or other forms of seals are stamped out by means of dies,
engraved dies being used when a device is required to be produced, and
thus at one operation the shaping and embossing of the seal is effected.
It should be remarked that this Invention applies to the sealing of
bottles of various kinds, and other articles on which sealing wax has
heretofore been used for securing the same from 'being tampered with.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry Kleinau in the Great Seal Patent Office on
the 12th May 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
KLEINAU, of King William Street, Strand, in the County of Middlesex,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twelfth day of November, in the year
of our Lord One thousand eight hundred and seventy-five, in the
thirty-ninth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Henry Kleinau, Her special
licence that I, the said Henry Kleinau, my executors, administrators,
and assigns, or such others as I, the said Henry Kleinau, my executors,

page_text: administrators, and 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 ADHESIVE SEALS," being a communication to me from
abroad by Adolph Teysonniere, of Paris, in the Republic of France,
upon the condition (amongst others) that I, the said Henry Kleinau,
my executors or administrators, by an instrument in writing under
my, or their, or one of their hands and seals, 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 Henry Kleinau, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement (that is to say):-
The chief object of this Invention is to remedy the inconveniences
hitherto attendant on the use of preparations of wax and equivalent
materials in the sealing of letters and parcels.
Instead of preparing the sealing wax in sticks, as heretofore, and
igniting the wax to effect a deposit on the paper suitable for the pro-
duction of a seal, it is now proposed to manufacture the composition in
the form of pastilles or thick wafers, which may take any desired shape,
say, that of a disc, lozenge, or oval, and to emboss on the same when
desired a monogram or device.
In applying this article as a seal to a letter it will only be necessary,
by the aid of a clip, to present its under side to the heat of a burning
taper, and while still soft to press it gently on the letter. When however
the sealing wax pastille is prepared without a device the softening of it
by the taper heat will enable it to receive the pressure of an office stamp
or signet ring, as ordinarily applied in the sealing of documents.
The seals may be prepared in various ways, but that preferred is to
pass a thin tissue, say, of paper or a woven fabric through a bath of wax
composition or equivalent material, and thereby to obtain a deposit or

page_text: coating of the composition on both sides of the tissue. From the
adhesive sheet thus prepared circular or other forms of pastilles are
stamped out by means of punches or discs. When a device is required
to be produced engraved dies are used, and thus at one operation the
shaping and embossing of the sealing wax pastille is effected.
It should be remarked that this Invention applies not only to the
preparation of seals for letters, deeds, and other documents, but also to
seals for bottles of various kinds, and other articles of mechandize on
which sealing wax has heretofore been used for securing the same from
being tampered with..
In conclusion I would state that I do not confine myself to the means
described for producing the pastilles of sealing wax, nor to the materials
mentioned for their composition, but what I claim as the Invention of
" Improvements in the Manufacture of Adhesive Seals," secured to me,
under the above in part recited Letters Patent is, the manufacture of
adhesive seals, whether plain or carrying a monogram or an ornamental
or other device from a tissue coated with sealing wax or its equivalent,
and giving strength and tenacity to the impressible and adhesive.
material.
In witness whereof, I, the said Henry Kleinau, have hereunto set
my hand and seal, the Twelfth day of May, in the year of our
Lord One thousand eight hundred and seventy-six.
HENRY KLEINAU. (L.S.)
