PROVISIONAL SPECIFICATION left by the said William Hargreaves at
the Office of the Commissioners of Patents, with his Petition, on the
31st January 1857.
I, WILLIAM HARGREAVES, of Bradford, in the County of York, Machine
Wool Comber, do hereby declare. the nature of the said Invention for "IM-
PROVEMENTS IN MACHINERY FOR PREPARING AND COMBING WOOL, HAIR, SILK, COTTON,
FLAX, AND OTHER FIBROUS SUBSTANCES," to be as follows:-
My Invention is by means of a cylinder with a quantity of combs attached
thereto, each comb to liave a sliding doffer to strip the combs as they proceed,
and also a porcupine connected to a pair of, drawing rollers,, the porcupine.to
work only a part of a. revolution at a time, so as the drawing rollers will strip
the porcupine in separate. feeds every time the porcupine moves or makes a
part of a revolution.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Hargreaves in the Great Seal Patent Office on the
31st July 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
HARGREAVES, of Bradford, in the County of York, Machine Wool Comber,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirty-first day of January, in the year of our Lord One
thousand eight hundred and fifty-seven, in the twenty-first year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
William Hargreaves, Her special licence that I, the said William Hargreaves,
my executors, administrators, and assigns, or such others as I, the said William
Hargreaves, 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 FOR
'PREPARING AND COMBING WOOL, HAIR, SILK, COTTON, FLAX, AND OTHER FIBROUS
SUBSTANCES," upon the condition (amongst others) that I, the said William
Hargreaves,, 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 William Hargreaves, do hereby declare
the nature of the said Invention, and in what manner the sanie is to be
performed, to be particularly described and ascertained in and by the following
.statement (that is to say):-
My Invention consists in certain new mechanical arrangements, which is as
follows: By means of a cylinder with a quantity of combs attached thereto,
each comb to have a sliding doffer to strip the combs as they proceed, and also a
porcupine connected to a pair of drawing rollers, the porcupine to work only a part
of a revolution at a time, and then make a complete stand, so that the drawing
rollers will strip the porcupine in separate feeds every time the porcupine movės
or makes a part of a revolution, as shewn in the Drawing, Fig..1, of which there
A
are two views A and B. A is a top view or ground plan; B, a side elevation.

page_text: The letter C in Fig. 1, is an endless cloth which feeds the porcupines D, and
A
then it is taken from the porcupines D by the combs attached to the cylinder E,
'with sliding doffers attached to each comb. The sliding doffers deposits the
wool, &c. upon another endless cloth F. The endless cloth F passes the wool,
&c. into the feed rollers H, which rollers delivers it to the porcupine I'; the
porcupine I makes a part of a revolution at a time, and then makes a complete
stand. The roller K presses the wool, &c. into the porcupine I, working a
part of a revolution at a time. The drawing rollers L receives separate feeds
from the porcupine every time it moves, it then deposits its feed' under the
roller O, and on to a third endless cloth M; it then passes the wool, &c. on to
the broaches of the comb N, N, N, N, to be drawn off. In Fig. 2.Drawing
there are two views, a ground plan and side elevation, which is the first part
of my Invention, and that is the cylinder with the combs and sliding doffers
attached thereto. There are also five Drawings of the combs and sliding
doffers, as follows:-a is the comb; b, the slide; c is the comb and sliding
doffer attached; d is the front part of the sliding doffer; and e is the per-
spective view of the whole.
In Fig. 3 there are also two views, a ground plan and a side elevation,
which shews the second part of my Invention; that is, the porcupine attached
to a pair of drawing rollers, the porcupine working a part of a revolution at a
time and then making a complete stand, so that the drawing rollers will strip
the porcupine in seperate feeds every time the porcupine moves or makes a
part of a revolution, as shewn in the Drawings.
I claim the right of using my improvements jointly in one machine, or
separately in two machines, as shewn in the Drawings 1, 2, & 3. The
particulars of my improvements consists of the sliding doffers, and also the
porcupine or any other sharp-pointed instrument moving a part of a revolution
at a time, or by means of gills sliding, travelling, or moving a part at a time,
and then making a complete stand, so as to cause the rollers to strip the
porcupine or gills in separate feeds every time they either move or slide; but
I prefer the porcupine just for simplicity only, as shewn in the Drawings.
Having thus described and set forth the nature and object of my said
Invention of improvements in machinery for preparing and combing wool,
hair, silk, cotton, flax, and other fibrous substances, together with the
manner in which the same is to be and may be carried into practical effect,
I would remark, in conclusion, that I claim as my Invention the general
arrangement of the apparatus above described, and shewn in the Drawings
annexed, constituting a machine for preparing and combing wool, hair, silk,

page_text: cotton, flax, and other fibrous substances, and more especially the sliding doffers
attached to the combs, and also the porcupine or any other sharp-pointed
instrument moving a part of, a revolution at a time, or by means of gills
sliding, travelling, or moving a part at a time and then making a complete
stand, so as to cause the rollers to strip the porcupine or gills in separate feeds
every time they either move or slide.
In witness whereof, I, the said. William Hargreaves, have hereunto
set my hand and seal, this Twenty-ninth day of July, in the. year of
our Lord One thousand eight hundred and fifty-seven.
Witness,
(Signed) WILLIAM HARGREAVES. (L.S.)
