IMPROVEMENTS IN THE MANUFACTURE OF WATERPROOF PACKING PAPER AND CLOTHS OR FABRICS."
Year: 1875

page_text: LETTERS PATENT to James Weston Clayton, of Hampton, in the
County of Middlesex, for the Invention of "IMPROVEMENTS IN THE
MANUFACTURE OF WATERPROOF PACKING PAPER AND CLOTHS OR FABRICS."
PROVISIONAL SPECIFICATION left by the said James Weston Clayton
at the Office of the Commissioners of Patents, with his Petition, on
the 27th April 1875.
I, JAMES WESTON CLAYTON, of Hampton, in the County of Middlesex,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
THE MANUFACTURE OF WATERPROOF PACKING PAPER AND CLOTHS OR FABRICS," to
be as follows:—
My improvements in the manufacture of waterproof packing paper
and cloths or fabrics consist in the employment of a certain composition,
as hereafter described, which is applied to the paper, cloth, or fabric in a

page_text: hot state, that is, when melted by heat. This composition does not
contain any spirit or other evaporable or oxidizing or drying ingredient,
but the paper, cloth, or fabric is finished by the cooling of the compo-
sition, which it does in a few seconds. This composition is applied to
the paper, cloth, or fabrics by machinery similar to that described in the
Specification of my Patent dated 25 March 1874, No. 1037, as shown in
Figures 2 and 3, 4 and 5. The machinery may however be made stronger,
and the troughs in which the materials are supersaturated with the
composition may be made of greater length than is described in the
aforesaid Specification.
The composition above referred to is mainly composed of common
resin, which has added thereto any fatty or oily substance for the
purpose of making it softer, pliable, and less brittle than common rosin
ordinarily is. Good proportions I find to bc, say, three or four parts of
common rosin to one part of rosin oil, or say, 4 or 5 parts of common
resin with one part of palm oil, but I do not confine myself to these pro-
portions, the Invention essentially consisting of a composition consisting
substantially of rosin rendered softer or pliable by an oily or fatty
substance, and applied as aforesaid.
SPECIFICATION in pursuance of the conditions of the Letters Patent, 2
filed by the said James Weston Clayton in the Great Scal Patent
Office on the 27th October 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
WESTON CLAYTON, of Hampton, in the County of Middlesex, send
greeting.

WHEREAS Her most Excellent Majesty Queen Victoria, by Her

cessors, give and grant unto me, the said James Weston Clayton, Her 3
special licence that I, the said James Weston Clayton, my executors, ad-

page_text: Clayton, my executors, 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,
usc, 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 WATERPROOF PACKING PAPER AND
CLOTHS OR FABRICS," upon the condition (amongst others) that I, the
said James Weston Clayton, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and
scals, 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 James Weston Clayton, do hereby
declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement thereof, that is to say :-
My improvements in the manufacture of waterproof packing paper
and cloths or fabrics consist in the employment of a certain composition,
as hereafter described, which is applied to the paper, cloth, or fabric in a
hot state, that is, when melted by heat. This composition does not
contain any spirit or other evaporable or oxidizing or drying ingredient,
but the paper, cloth, or fabric is finished by the cooling of the compo-
sition, which it does in a few seconds. This composition is applied to
the paper, cloth, or fabrics by machinery similar to that described in the
Specification of my Patent dated 25 March 1874, No. 1037, as shown in
Figures 2, 3, 4, and 5. The machinery may however be made stronger,
and the troughs in which the materials are supersaturated with the
composition may be made of greater length than is described in the
aforesaid Specification.
The composition above referred to is mainly composed of common
resin, which has added thereto any fatty or oily substance for the
purpose of making it softer, pliable, and less brittle than common rosin
ordinarily is. Good proportions I find to be, say, three or four parts of
common rosin to one part of rosin oil, or say, 4 or 5 parts of common

page_text: resin with one part of palm oil, but I do not confine myself to these
proportions, the Invention essentially consisting of a composition con-
sisting substantially of rosin rendered softer or pliable by an oily or fatty
substance, and applied as aforesaid.
In witness whereof, I, the said James Weston Clayton, have here-
unto set my hand and seal, this Twenty-seventh day of October,
in the year of our Lord Onc thousand eight hundred and seventy-
five.
JAMES WESTON CLAYTON. (L.S.)
