Year: 1869

page_text: LETTERS PATENT to Thomas Briggs, of Manchester, in the County
of Lancaster, Tarpauling Manufacturer, for the Invention of "Iм-
PROVEMENTS IN THE MANUFACTURE OF MATERIALS USED FOR PACKING AND
OTHER PURPOSES."
Sealed the 22nd April 1870, and dated the 27th October 1869.
PROVISIONAL SPECIFICATION left by the said Thomas Briggs at
the Office of the Commissioners of Patents, with his Petition, on
the 27th October 1869.
I, THOMAS BRIGGS, of Manchester, in the County of Lancaster,
Tarpauling Manufacturer, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN THE MANUFACTURE OF MATERIALS USED FOR
PACKING AND OTHER PURPOSES," to be as follows:-
My Invention consists in an improved mode of combining textile
fabrics and paper, and coating the same with oil, tar, pitch, or other

page_text: water repellant, thereby producing a material which may be used for
packing, covering roofs, brattice cloth, and other purposes.
The mode of operation is to cover the paper, or both paper and the
textile fabric, with a thin coating of paste or other adhesive substance,
and passing them together between pressing rollers; and thence passing
them over drying cylinders and through a calender. The combined
material may then be at once passed through the oil, tar, or other water
repellant, and be completed in one continuous operation, or the com-
bined paper and fabric may be subjected to the waterproofing process as
a separate operation. The combined material may also be embossed or
left plain.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Thomas Briggs in the Great Seal Patent Office
on the 26th April 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
BRIGGS, of Manchester, in the County of Lancaster, Tarpauling
Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-seventh day of October, in the
year of our Lord One thousand eight hundred and sixty-nine, in the
thirty-third year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Thomas Briggs, Her special licence that
I, the said Thomas Briggs, my executors, administrators, and assigns,
or such others as I, the said Thomas Briggs, my executors, adminis-
trators, 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 MATERIALS USED FOR PACKING AND OTHER PUR-
POSES," upon the condition (amongst others) that I, the said Thomas
Briggs, my executors or administrators, by an instrument in writing

page_text: 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 Thomas Briggs, do hereby declare
the nature of my said Invention, and in what manner the same may be
performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say:-
My Invention consists in an improved mode of combining textile
fabrics and paper, and coating the same with oil, tar, pitch, or other
water repellant, thereby producing a material which may be used for
packing, covering roofs, brattice cloth, and other purposes.
The mode of operation is to cover the paper or the textile fabric, or
both paper and the textile fabric, with a thin coating of paste or other
adhesive substance by any of the usual and well known means. The
substances are then to be combined by being passed between pressing
rollers, and afterwards dried by passing over heated drying cylinders
and through a calender; they are thence passed through the coating
machine usually employed in the manufacture of waterproof substances,
and then if necessary stoved or dried. The materials may be corrugated
or embossed by any of the usual processes or may be left plain.
Having now described and particularly ascertained the nature of my
said Invention, and the manner in which the same is or may be used or
carried into effect, I would observe in conclusion that I do not confine
or restrict myself to the precise details or arrangements or mode of
operation which I have had occasion to describe or refer to, as many
variations may be made therefrom without deviating from the principles
or main features of my said Invention; but I would have it distinctly
understood that I lay no claim to the separate and distinct parts of the
process herein-before described and referred to, except when employed
in combination as and for the purposes above mentioned; but what I
consider to be novel and original, and therefore claim as my Invention
is,
Firstly. The above described mode of combining textile fabrics and

page_text: Secondly. The application of water repellant materials to the sub-
stances combined by that method.
In witness whereof, I, the said Thomas Briggs, have hereunto set
my hand and seal, this Twenty-fifth day of April, in the year of
our Lord One thousand eight hundred and seventy.
Witness to the signature of the
said Thomas Briggs,

Patent Agent,
