IMPROVE- MENTS IN MACHINERY OR APPARATUS FOR RAISING THE NAP ON WOOLLEN CLOTHS
Year: 1858

page_text: LETTERS PATENT to John Dawson, of Holbeck, in the Parish of Leeds,
in the County of York, Machine Maker, for the Invention of "IMPROVE-
MENTS IN MACHINERY OR APPARATUS FOR RAISING THE NAP ON WOOLLEN
CLOTHS."
PROVISIONAL SPECIFICATION left by the said John Dawson at the
Office of the Commissioners of Patents, with his Petition, on the 6th
December 1858.
I, JOHN DAWSON, of Holbeck, in the Parish of Leeds, in the County of
York, Machine Maker, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR RAISING THE NAP ON
WOOLLEN CLOTHS," to be as follows:-
I draw the cloth or fabric through a suitable number of rollers arranged at
one end of the machine, so as to keep it straight, from which I pass it over
the raising cylinders to be delivered on to an apparatus fixed above the top of
the said cylinders, having an endless revolving motion where the cloth or fabric
falls in folds, from whence it passes to and through other rollers fixed at the
other end of the machine, and from thence to pass again over the raising
cylinders, which operation is repeated until the nap is sufficiently raised.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Dawson in the Great Seal Patent Office on the
6th June 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
DAWSON, of Holbeck, in the Parish of Leeds, in the County of York, Machine
Maker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixth day of December, in the year of our Lord
One thousand eight hundred and fifty-eight, in the twenty-second year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said John Dawson, Her special licence that I, the said John Dawson, my
executors, administrators, and assigns, or such others as I, the said John
Dawson, 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, 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 MACHINERY
OR APPARATUS FOR RAISING THE NAP ON WOOLLEN CLOTHS," upon the con-
dition (amongst others) that I, the said John Dawson, my executors, or
administrators, by an instrument in writing 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 John Dawson, do hereby declare
the nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement (that is to say):-
I draw the cloth or fabric, of which the nap has to be raised, through a
suitable number of rollers arranged at one end of the machine, so as to keep
it straight and in a proper state of tension, and pass it over the raising
cylinders, from which it is delivered on to an apparatus on the top of the
machine having an endless revolving motion on which the cloth or fabric falls
in folds, from whence it passes to and through other rollers fixed at the other
end of the machine, and from thence to pass again over the raising cylinders,
which operation is repeated until the nap is sufficiently raised. I thus dispense
with an attendant at the delivering part of the machine, my apparatus being
self-acting.

page_text: The peculiar construction of my said machine, and the manner of working
the same, will be clearly understood by reference to the accompanying Sheet
of Drawings and the letters of reference thereon.
The Drawing is a side elevation of my improved machine, in which A
represents the delivering roller; B, B, B, the stretching rollers; C, C, C, the
drawing rollers; D, the travelling seray, having an endless motion; E, E, E,
worms and worm wheels for raising or lowering the stretching rollers. The
modus operandi is as follows:--The cloth or fabric F passes over the delivery
roller A on to the travelling scray D, where it falls in folds, from whence it is
taken up by the drawing rollers C, passing to the stretching rollers B, B, B,
over the raising cylinders to the delivery roller A again, the operation being
thus repeated as often as necessary by the continuous self-acting motion or
process; the said machine or apparatus being driven by any suitable gearing,
motion being given to it either by hand or power.
Having thus fully described the nature of my said Invention, and the
manner in which the same is to be performed, I desire it to be distinctly
understood that I do not claim any of the parts of the said machine separately;
but I claim as my Invention, and which to the best of my knowledge and
belief has not been hitherto used within the realm, the construction and com-
bined arrangement of rollers to keep the cloth or fabric, of which the nap has
to be raised, in a straight form and a proper state of tension, passing it con-
tinuously over the raising cylinders and on to a travelling scray, where it is
laid in folds; and also the mechanical arrangement of working the same, as
herein described, and illustrated in the accompanying Sheet of Drawings.
In witness whereof, I, the said John Dawson, have hereunto set my
hand and seal, this Second day of June, in the year of our Lord One
thousand eight hundred and fifty-nine.
Witness,
WILLIAM HORSFIELD.
JOHN DAWSON. (L.S.)
