PROVISIONAL SPECIFICATION left by the said Robert Benjamin Brassey
and James Hargreaves at the Oflice of the Commissioners of Patents,
with their Petition, on the 20th July 1863.
We. ROBERT BENJAMIN BRASSEY. of Ashton-under-Lyne, in the County of
Lancaster, Manufacturer. and JAMES HARGREAVES. of the same Place.
Manager. do hereby declare the nature of the said Invention for "IMPROVE.

to be as follows:
Our improvements are chiefly applicable to the machines for sizing and
drying yain known as slashers and tape machines, and they consist in
dispensing with one of the usual drying cylinders, and in applying to the other
drying cylinder a close fitting cover. which is in communication with a flue in

SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Robert Benjamin Brassey and James Hargreaves in the
Great Seal Patent Office on the 19th January 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, ROBERT
BENJAMIN BRASSEY, of Ashton-under-Lyne, in the County of Lancaster,
Manufacturer, and JAMES HARGREAVES, of the same Place, Manager, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twentieth day of July, in the year of our Lord
One thousand eight hundred and sixty-three, in the twenty-seventh year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
us, the said Robert Benjamin Brassey and James Ilargreaves, Her special
license that we, the said Robert Benjamin Brassey, and James Hargreaves,
our executors, administrators, and assigns, or such others as we, the said
Robert Benjamin Brassey, and James Hargreaves, our executors, administra-
tors, 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 SIZING AND
DRYING YARNS AND FABRICS," upon the condition (amongst others) that wc,
the said Robert Benjamin Brassey, and James Hargreaves, our executors or
administrators, by an instrument in writing under our, or their, or one of our
or 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 we, the said Robert Benjamin Brassey, and James
Hargreaves, do hereby declare the nature of our said Invention. and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement (that is to say):--
Our improvements are chiefly applicable to the machines for sizing and

page_text: drying yarn known as "slashers" and "tape machines," and they consist in
dispensing with one of the usual drying cylinders, and in applying to the other
drying cylinder a close fitting cover, which is in communication with a flue in
which a partial vacuum is formed by a fan, or other suitable means. The
yarn is guided to and from the drying cylinder in such wise that it passes
nearly entirely around it, and the increased evaporation produced by the
partial vacuum in the cover causes the yarn to dry rapidly. When our
improvements are applied to drying fabrics, the cover in which the partial
vacuum is formed is applied to one or more drying cylinders around which the
fabric passes.
And in order that our Invention may be fully understood, we will proceed
to describe the accompanying Drawing, which represents part of an ordinary
tape sizing machine to which our improvements are applied.
a is the trough, containing the size and the rollers b, b, by which the size is
given to the yarn; above the trough a is the cover c, which is in com-
munication with the fan d by the flue e; the object of the cover c and flue e is
to prevent the escape of the steam and smell of the size entering the room
and vitiating the atmosphere; the yarn on leaving the trough a is taken
under the fan roller f, the bars of which are narrow at the point, to prevent
the size from the yarn collecting upon them; after leaving the fan roller f
the yarn passes around the drying cylinder g, from which it is taken around
the guide rollers h, h, h, to the warp beam; the fan i is placed within the
bend of the yarn to increase the effect in cooling and drying it. Above the
cylinder is the close fitting cover j, which is also in communication with the
fan d by the fluck. When the machine is at work the rapid evaporation
produced by the partial vacuum within the cover; causes the yarn to dry
more expeditiously than heretofore, less steam is required for drying, the room
is kept comparatively cool and free from steam, and by not subjecting the
yarn to so great heat it retains its strength and elasticity. When our improve-
ments are applied to drying fabrics, the cover in which the partial vacuum is.
formed is applied to one or more of the drying cylinders around which the
fabric passes.
Having thus stated the nature of our Invention, and described the manner
of performing the same, we declare that we claim, the use and application
of close fitting covers to the drying cylinders of "slashers" and "tape
machines," or other machines for drying yarns and fabrics, in which cover
or covers a partial vacuum is formed, in the manner and for the purposes
described.

page_text: We also claim the peculiar construction of the fan roller as applied to
machines for drying yarns and fabrics.
In witness whereof, we, the said Robert Benjamin Brassey and James
Hargreaves, have hereunto set our hands and seals, this Eighteenth
day of January, in the year of our Lord One thousand eight hundred
and sixty-four.
