IMPROVEMENTS IN THE MANU- FACTURE OF KAMPTULIGON
Year: 1851

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, LOCKINGTON
SAINT LAWRENCE BUNN, of Walbrook, in the City of London, Merchant,
send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Seventh day of August,
One thousand eight hundred and fifty-one, in the fifteenth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Lockington Saint Lawrence Bunn, my exors, adñiors, and assigns, Her
especial licence, full power, sole privilege and authority, that I, the said
Lockington Saint Lawrence Bunn, my exors, adññors, and assigns, or such
others as I, the said Lockington Saint Lawrence Bunn, my exors, admors, or
assigns, should at any time agree with, and no others, from time to time
and at all times during the term of years therein expressed, should and
lawfully might make, use, exercise, and vend, within England, Wales, and the
Town of Berwick-upon-Tweed, my Invention of "IMPROVEMENTS IN THE MANU-
FACTURE OF KAMPTULIGON;" in which said Letters Patent is contained a proviso
that I, the said Lockington Saint Lawrence Bunn, shall particularly describe
and ascertain the nature of my said Invention, and in what manner the same
is to be performed, by an instrument in writing under my hand and seal, to
be inrolled in Her Majesty's High Court of Chancery within six calendar
months next and immediately after the date of the said in part recited Letters
Patent, as in and by the same, reference being thereunto had, will more
fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
Lockington Saint Lawrence Bunn, do hereby declare that the nature of my
said Invention, and the manner in which the same is to be performed, are
fully described and ascertained in and by the following statement thereof,
that is to say :-
My Invention consists in the improvements as herein-after described, and
application of the composition known by the name of "Kamptulicon," for
which Letters Patent were granted to Elijah Galloway on the Fourteenth day
of February, One thousand eight hundred and forty-four, and which consisted
of manufacturing certain combinations of materials to be used as a substitute
for canvas and other surfaces employed as grounds for painting, some of
which combinations are applicable to other purposes.
Now the peculiarity of my Invention consists of, first, of giving strength
and firmness to "kamptulicon," and to render it more durable than it is at
present, and to prevent it from contracting when subjected to different
temperatures; and I accomplish this object by placing any woven fabric (by
preference an openly woven canvas), wire guaze, or perforated metal, between
two layers or thin sheets of "kamptulicon," which are caused to adhere to
each other by penetrating through the reticulation of the canvas or materials
employed; and I accomplish this object by causing the masticated caoutchouc
combined with cork dust or other matters, as heretofore employed, to be
rolled or spread over the two sides of canvass or wire cloth or reticulate sheets
above mentioned, and when dry and cold I cause the same to have one or
both sides painted and ornamented, according to the uses to which such sheets
are to be applied; or I can have a surface of canvass or woven fabric on the
outside to be painted and ornamented.
The second part of my improvements consists in facing or coating the
surfaces of " kamptulicon" (with or without fabrics or reticulate sheets
between them or on the surface) with "kamptuliçon" colored in the mass by
the addition of suitable pigments, which is effected by previously dyeing or
staining the cork dust before mixing with the india rubber to the required
colors, or I mix suitable pigments with the cork dust as stained, thus producing
a solid colored surface at a much less cost than when the sheets are colored
throughout the entire mass or sheet. I also coat blocks of "kamptulicon
by the same method, using at times india rubber or other solution to unite
them in preference to heat or rollers.
"
Thirdly, I improve the appearance of "kamptulicon" pavement, or other
uses, by forming them of a mosaic or other pattern in the following manner :-
I color "kamptulicon" in the masticator by the addition of pigment or coloring

page_text: matter, and while in a plastic state I press or mould it into different forms.
I then place the pieces so formed side by side, varying the colors to arrive at
any desired pattern, using india-rubber solution or other suitable adhesive
matter to the pieces so put together; and I cut the combined mass into
veneers or sheets, which I use in that form, or I cement or affix them to sheets
or blocks of "kamptulicon."
Having thus described the nature of my Invention, and the manner of per-
forming the same, I would have it understood that what I claim is,—
Firstly, the application of woven fabrics, wire guaze, perforated metals, or
other similar materials between two layers or sheets of kamptulicon, and
printing and ornamenting the same, as described.
Secondly, I claim the manufacture of sheets, blocks, or layers of kamptulicon
combined with pigments or other coloring matter on to other kamptulicon in
an uncolored state.
Thirdly, I claim the manufacture of "kamptulicon" into mosaic or other
patterns, either for pavements or other purposes.
In witness whereof, I, the said Lockington Saint Lawrence Bunn, have
hereunto set my hand and seal, this Seventh day of February, in the
year of our Lord One thousand eight hundred and fifty two
