TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JACQUE
KLOET, of Manchester, in the County of Lancaster, Gentleman, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at Westmin-
ster, the Seventeenth day of February, in the ninth year of Her reign, and in
the of our Lord One thousand eight hundred and forty-six, did, for Herself,
Her heirs and successors, give and grant unto me, the said Jacque Kloet, Her
especial license, full power, sole privilege and authority, that I, the said Jacque
Kloet, my executors, administrators, and assigns, and such others as I, the
said Jacque Kloet, my executors, administrators, 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 expressd, should and lawfully might make, use, exercise,
and vend, within England and Wales and the Town of Berwick-upon-Tweed,
my Invention of "A CERTAIN IMPROVED COMBINATION OF MATERIALS TO BE USED
AS A SUBSTITUTE FOR LEATHER OR FOR WA
WATERPROOF CLOTH AND OTHER SIMILAR
PURPOSES;" in which said Letters Patent is contained a proviso that I, the
said Jacque Kloet, shall cause a particular description of the nature of my
said Invention, and in what manner the same to be performed, to be
enrolled in Her Majesty's Court of Chancery within six calender months
next and immediately after the date of the said in part recited Letters Patent,

page_text: as in and by the same, reference being thereunto had, will more fully and at
large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Jacque Kloet, do hereby declare that the nature of my Invention, and the
manner in which the same is to be performed, is particularly described and
ascertained in and by the following explanation thereof, (that is to say) :-
My Improved Combination of Materials to be used as a Substitute for
Leather or for Waterproof Cloth and other similar Purposes, consists chiefly
in a preparation of linseed oil, hereafter described, in combination with a
solution of caoutchouc or indian rubber and other ingredients herein-after
mentioned, to be applied to one or both sides of any cloth or fabric, either
manufactured from cotton, wool, or any other fibrous material. The linseed
oil to be employed for the above purpose is prepared in the following manner:
-Put twenty pounds of linseed oil and two pounds of coarse bread into a
copper vessel of sufficient size to contain four times that quantity; the oil
must then be boiled until the froth or scum is boiled off, and as soon as
the bread is observed to rise to the surface of the oil the bread must be
taken out and the oil will be found fit for use, the bread having absorbed or
taken up all the impurities. When the oil is sufficiently boiled, add some
spirits of turpentine and then ignite the oil; let it burn about ten minutes to
evaporate the spirit and extinguish the flames; after which take some of the
oil with a small iron ladle, and let fall a few drops on a piece of flat glass,
which must be examined whether it has long threads or fibres. If this proves
to be the case the operation is completed. After the examination close the
vessel immediately and put some wet woollen cloth on it, in order that no air
can get in; then let it cool and pour some cold water on it to prevent the
surface from getting dry and unfit for use. The solution of caoutchouc must
be prepared as follows:-Take one pound of caoutchouc, cut in pieces, and boil
the same two hours in water. After it is well boiled it must be wiped dry and
cut again into smaller pieces; then add sixteen pounds of spirits of turpentine
and let it stand five days or thereabouts in a glazed pan, being careful that
the pan is covered so that no air can get into it; let it then be placed in a
copper vessel over a slow fire and boil gently, stirring it frequently with an
iron instrument until the whole of the caoutchouc is dissolved; after which,
strain the solution, and it is then ready for use. In using the above prepara-
tions for manufacturing my improved substitute for leather or waterproof
cloth, a piece of cloth or other fabric composed of cotton, wool, or other fibrous
material of the required texture and size, must be distended evenly and tightly
in a suitable frame. Then take some of the dissolved caoutchouc above

page_text: described, and a little siccative or drying oil, and spread it evenly upon the
cloth with a suitable instrument. After it has been left a day to dry, take
some of the linseed oil prepared as above, with a small quantity of acetate or
sugar of lead and a little drying oil, and apply that also, rubbing it well
through the cloth, in order to fill up the interstices between the threads of the
same; then let it be again dryed. After which, take one part of the solution
of indian rubber, one part of the prepared linseed oil, a little acetate or sugar
of lead, and a little siccative or drying oil; mix the ingredients well together
with a little "lamp black," and lay this composition on to the cloth the
required thickness; then wash the surface over with some boiled linseed oil,
and let it dry again; after which, rub it well with a pumice stone until the
surface is quite smooth. This done, wipe the surface with some clean linen
rags and let it dry again for a day or two; then varnish it all over with black
varnish (or other suitable color), and when dry, take some very finely ground
pumice stone, and with a rubber, made of list or other suitable material, rub
it over the cloth until it assumes a dull appearance, exactly similar to leather.
The operation is then complete, and cloth thus prepared forms my improved
substitute for leather, &c., and when taken from the frame and the edges cut
off, it is ready for the market. If any other color than black is required, any
suitable colouring matter must be introduced instead of "lamp black," and
the varnish wherewith it is varnished must be colourless.
In witness whereof, I, the said Jacque Kloet, have hereunto set my hand
and seal, this Fifteenth day of August, One thousand eight hundred and
