IMPROVEMENTS IN THE TREATMENT OF WOOL AND OTHER FIBRES IN THE PROCESS OF PREPARING
Year: 1873

page_text: LETTERS PATENT to Edward Holden, of the Firm of Isaac Holden
and Sons, of Bradford, in the County of York, for the Invention
of "IMPROVEMENTS IN THE TREATMENT OF WOOL AND OTHER FIBRES IN THE
PROCESS OF PREPARING."
PROVISIONAL SPECIFICATION left by the said Edward Holden at the
Office of the Commissioners of Patents, with his Petition, on the
81st March 1873.
I, EDWARD HOLDEN, of the Firm of Isaac Holden & Sons, of
Bradford, in the County of York, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN THE TREATMENT OF WOOL AND OTHER
FIBRES IN THE PROCESS OF PREPARING," to be as follows:-
-
The object of the Invention is to secure increased uniformity to the
size or form of the sliver obtained when preparing the fibres by a
combing process.

page_text: machinery, and a drawing leather in the form of a sliver which is at
once conducted to cans or receivers in the slivers obtained, and the
result is that the slivers obtained vary very much in quantity at different
parts of them, and considerable waste is sustained.
To remedy these evils when preparing fibres by a combing process
before final combing, in place of at once conducting away the sliver
obtained, I by means of an extra pair of rollers and an endless belt or
apron applied to act with the ordinary drawing-off leather, accumulate
the slivers into sheets, by which I find greatly increased uniformity is
secured in the combing and in the subsequent operations on the fibre.
SPECIFICATION filed in pursuance of the conditions of the Letters
Patent, and of an Order of the Lord Chancellor, by the said
Edward Holden in the Great Seal Patent Office on the 11th
October 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
HOLDEN, of the Firm of Isaac Holden and Sons, of Bradford, in tho
County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirty-first day of March, in the year
of our Lord One thousand eight hundred and seventy-three, in the
thirty-sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Edward Holden, Her special licenso
that I, the said Edward Holden, my executors, administrators, and
assigns, or such others as I, the said Edward Holden, 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 THE
TREATMENT OF WOOL AND OTHER FIBRES IN THE PROCESS OF PREPARING," upon
the condition (amongst others) that I, the said Edward Holden, 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

page_text: Seal Patent Office on or before the Fourteenth day of October One
thousand eight hundred and seventy-three.
NOW KNOW YE, that I, the said Edward Holden, do hereby declare
the nature of the 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 :-
The object of the Invention is to secure increased uniformity to the
size or form of the sliver of wool or other fibres obtained when preparing
such fibres by a combing process.
By arrangements generally adopted in preparing wool and other fibres
by combing processes, the fibre is drawn from the circle or other
character of holding combs in the form of a sliver, by drawing-off
rollers aided by a drawing leather, and such sliver as thus drawn off is
at once conducted to and accumulated in cans or such like receivers.
The result is that slivers so obtained vary very materially in quantity
at different parts of their length, and it is found that in consequence of
such irregularity considerable waste of fibre is sustained.
To remedy these evils when preparing fibres by a combing process
before the final combing of them, in place of at once conducting away
the sliver obtained, I apply an extra pair of rollers and an endless belt
or apron to act with the ordinary drawing-off leather, in order thereby
to accumulate the slivers into "sheets" to be fed after a gilling process
to the final combing, by which I find greatly increased uniformity is
secured in the final combing and in the subsequent operations on the
fibre.
Having thus described by Invention and means which I adopt in
carrying the same into effect, I would have it understood that what I
claim is the method of operating in the preparing of wool and other
fibres before combing, substantially as described.
In witness whereof, I, the said Edward Holden, have hereunto set
my hand and seal, this Twentieth day of September in the year
of our Lord One thousand eight hundred and seventy-three.
