IMPROVE- MENTS IN THE MANUFACTURE OF WOOLLEN CLOTH
Year: 1849

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
GIBLETT, of Trowbridge, in the County of Wilts, Gentleman, 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 Tenth day of
February, One thousand eight hundred and forty-nine, in the twelfth year
of Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said John Giblett, my exors, admors, and assigns, Her especial
licence, full power, sole privilege and authority, that I, the said John Giblett,
my exors, adiñors, and assigns, and such others as I, the said John Giblett,
my exors, adñiors, 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 "IMPROVE-
MENTS IN THE MANUFACTURE OF WOOLLEN CLOTH;" in which said Letters Patent
is contained a proviso that I, the said John Giblett, should cause a particular
description of 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 said Majesty's High Court of Chancery within six calendar
mouths next and immediately after the date of the said in part recited

page_text: Letters Patent, 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
John Giblett, do hereby declare that the nature of my said Invention, and
in what manner the same is to be performed, are fully described and ascer-
tained in and by the following statement thereof, that is to say :-
My Invention consists of applying heating apparatus to machinery employed
for washing woollen cloth, so as to separate or remove grease and other im-
purities before subjecting woollen cloth to the processes of milling and
dressing. And in order that my Invention may be most fully understood and
readily carried into effect, I will proceed to describe the means pursued
by me.
It is well known that warm liquor will remove grease and other impurities
from woollen cloth more quickly and effectually than cold liquor. Now the
object of my Invention is to combine with the washing apparatus employed
apparatus for heating or warming the liquor by a heat not moist but dry, so
that the liquor may be constantly kept warm during the process of washing
such woollen cloths before milling and dressing the same. For this purpose
I prefer to employ a coil of steam pipe submerged in the liquor, such steam
pipe being capable of heating and continuing the liquor heated to a tem-
perature of about 80 degrees of Fahrenheit heat, which is what I have
generally found to be the best for the purpose. Other dry heating apparatus
may be resorted to in place of steam pipes, but I prefer steam pipes, as the
desired temperature at which parties wish to work can be regulated more
readily than when using other means of heating, and which temperature I
have. found may be varied from seventy to ninety degrees of heat aforesaid,
according to the loosening of the grease in the cloths under process. The
process of washing in other respects will be carried on in the ordinary manner,
but the process will require much less time; and it will be found that the
cloths will not require to be soaked all night, but may, according to my
Invention, be put in the washer or washing machine combined with heating
apparatus, and finished off at any time of day.
Having thus described the nature of my Invention, and the manner in
which the same is to be performed, I would have it understood that I do not
claim the washing machinery separately, nor heating or warming apparatus
separately; but what I claim is the combining heating or warming apparatus
(by the means of a pipe or pipes, or other like apparatus, introducing into the
washing machine a dry heat for the purpose aforesaid), with machinery
employed for washing woollen cloths previous to milling and dressing them,

may be carried on by liquor kept constantly heated.
In witness whereof, I, the said John Giblett, have hereunto set my hand
and seal, this Seventh day of August, in the year of our Lord One
thousand eight hundred and forty-nine.
Enrolled the Tenth day of August, in the year of our Lord One thou-
sand eight hundred and forty-nine.
