page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
YOUNG HUNCLASS, of Lambeth Marsh, in the Parish of Saint Mary, Lambeth,
in the County of Surrey, Painter, do send greeting.
WHEREAS His most Excellent Majesty King George the Third did, by,
His Royal Letters Patent under the Great Seal of Great Britain, bearing date
at Westminster, the Fifteenth day of January, in the thirtieth year. of. His
reign, give and grant unto me, the said Samuel Young Hunclass, His especial
licence, full power, sole privilege and authority, that I, the said,Samuel Young
Hunclass, during the term of fourteen years therein expressed, should and.
lawfully might make, use, exercise, and vend,, within that part of the Kingdon
of Great Britain called England, the Dominion of Wales, Town of Berwick-
upon-Tweed, and also in all His said Majesty's Colonies and Plantations abroad,
my Invention of "A METHOD OF MAKING AND. RENDERING ELASTIC AND WATER-
PROOF ALL SORTS OF PAINTED, PRINTED, VARNISHED, OR JAPANNED LINNEN, COTTON,
WOOLLEN CLOTHS, STUFF, OR SILK, OR ANY OTHER MATERIAL INTERWOVEN THERE.
WITH;" in which said Letters Patent there is contained a provisoe, obliging.me,
the said Samuel Young Hunclass, by an instrument in writing under my hand
and seal, to particularly describe and ascertain the nature of my said Invention,
and in what manner the same is to be performed, and cause the same to be
inrolled in His Majesty's High Court of Chancery, within one calendar month
next and immediately after the date of the said Letters Patent, as in and by the
said Letters Patent (reference being thereunto had) may more fully and at
large appear.

page_text: NOW KNOW YE, that in compliance with the said provisoe, I, the said
Samuel Young Hunclass, do hereby declare that the nature of my said
Invention, and the manner in which the same is to be performed, is to be
particularly described and ascertained as follows, that is to say:-
My said method of making and rendering elastic and waterproof all sorts of
painted, printed, varnished, or japanned linnen cotton, wollen cloths, stuff,
or silk, or any other material interwoven therewith, consists in certain com-
positions of the several ingredients herein-after mentioned and described, and
prepared as herein-after is also mentioned and described, and also in a certain
method of laying the said compositions on, and working the same into the cloth
or other material intended to be made elastic and waterproof, as herein-after
is also mentioned and described, that is to say:-To make the said compositions;
take copal oil varnish, quince oil varnish, amber oil varnish, or black japan
oil varnish, together with lamblack or umber, pulverized and ground with any
kind of raw drying or etheriel oil for grinding colours; let the quantities of
lamblack or umber, when so ground, be equal in weight with the quantity
of varnish or japan intended to be used; when ground, mix the said quantities
of the said materials together, with a quantity of prepared boiled or drying
lintseed oil, sufficient to make the whole of the thickness or consistence of
common house paint, and the composition is complete. Or take of verdigris,
lamblack, Prussian, indigo, or other blues, each an equal quantity, to which
add a tenth part of such quantity of gold or silver litharge, or of copperas, or
of sugar of lead, ground in any oils that are used for grinding or mixing
with colours; to which add such a quantity of jappenners gold size, or black
japan, or copal varnish, or annamce varnish, or amber varnish, together also
with such a quantity of boiled or lintseed oil, made drying, as will be
sufficient to make the whole, when mixed together, of the thickness or con-
sistence of the common house paint, and the composition is complete; but
N.B., this composition is not quite so effectual nor so durable as the first.
Or take any quantity of spirit varnishes, of any kind, intermixt with the
like quantity of Baroch varnish, to which add such a quantity of any colours
of oakers, or of umber, burnt or raw, or of any other colours ground with
turpentine oil, spirit of turpentine, or turpentine varnish, as when mixed
together will make the whole of the thickness or consistence of common
house paint, and this composition is also complete; but, N.B., this compo-
sition is not so effectual or durable as the last. Or take any quantity of
common black or Burgundy pitch, or black or white rozen, to either add a
tenth part of such quantity of vitrol, boil all these materials together for one
hour, then add a sufficient.quantity of oil of coal, or coal varnish, to make it of

page_text: the thickness and consistence of common house paint, and this composition is.
also complete, and is equal in goodness to the last. Or take equal quantities.
of tar, oil of Jerran, or India lacker, spirit of wine lackers, Canadia balsam,.
Baroch or any other varnish, India ink, yellow coloured rasinous gum imported
from Port Jackson, near Botany Bay, and boil these materials together until,
the gum is dissolved, and when cold, this composition is complete and fit for
use, but is not so good or durable as the last. And the method of laying on
the said compositions, or working the same into the cloth or other material,
intended to be made elastic and waterproof, is as follows, that is to say:-:
First, put the cloth or other material on tenter hooks in a frame or any other
proper fastenings, and strain it as tight as it will bear, after which lay on with,
a common house-painter's brush, on the contrary side of the material to that
which you mean to be the smooth and right side, a coat of the composition,
which will penetrate the material to the other side; then let the material dry;,
when dry, lay on another coat of the composition, in like manner, on the:
intended smooth or right side, and immediately with a smooth flat shovel, or.
other such like instrument, drawn over the material on the intended smooth or
right side, remove the composition from the tops of the threads, if any should.
be there, and fill up the pores, continuing the process in like manner, with the
composition on the same side, smoothing and pressing it on and in the pores
of the material, until the threads of the material are completely covered over
with the composition, and the surface thereof is made smooth and even; then
when again dry, lay over with a common painter's brush two coats of either
of the above varnishes, or japan varnish; let it continue in the frame and on
the fastenings till the material is quite dry and hardened, and it is then com-
plete and fit to be ornamented with any paint or colour, or any other ornament
that fancy may invent. And in case it is wished to have the material prepared
in such a manner that one side thereof may remain nearly in its original state,
take of parchment or leather sise, melted and made warm, and such a quantity
of whiting, pounded and sifted fine, as when mixed together will make the
whole of the thickness of common paint, then with a common painter's brush,
while warm, lay two full coats on that side of the material which you intend to
remain as near as can be in its original state, and when dry proceed to lay on
the other side of the material either of the compositions before mentioned, in
the manner before described, until the threads of the material are completely
covered, and when dry and hard, with a sponge and warm water remove the
size and whiting from the side it was so laid on, and when rubbed dry the
material is elastic and waterproof, one side thereof nearly remaining in its
original state; but the material got up in the last manner is not so lasting and

page_text: durable as. when got up in the other way before described. Or take whiting, or
water white, or uniber, or oaker, or white lead, mix either of these materials:
with such a quantity of glew, boiled in water and brought to the weakness of
leather size, as will bring it to the consistence of common paint; use this
composition when warm to that side of the material which is wished to
remain as near as may be in its original state, and proceed therewith and
with the other side of the material as before mentioned, and the material is:
elastic and waterproof, one side thereof nearly remaining in its original state;
but got up in this way is not so lasting and durable as when got up in the
method last mentioned. Or take of gum Arabeck, or India glew, or isinglass,
or gum senega, or Poland or other starch, or paste, or wheaten or any other
flower, or lintseed or lintseed, cake, or strong water varnish, boiled in water
until dissolved, and brought to the consistence of common paint; use this
composition also to that side of the material which is wished to remain, as near:
as may be, in its original state, and proceed therewith, and with the other side
of the material as before mentioned, and the material is also elastic and water-
proof, one side thereof nearly remaining in its original state; but got up in.
this
way is not so durable as when done according to the last method..
In witness whereof, I, the; said Samuel Young, Hunclass, have hereto
set my hand and seal, this Eighth day of February, in the year of our
Lord One thousand seven hundred and ninety....
