Year: 1868

page_text: LETTERS PATENT to Joseph Holroyd Bolton, of Manchester, in the
County of Lancaster, for the Invention of "CERTAIN IMPROVEMENTS
IN MACHINERY OR APPARATUS FOR SIZEING AND DRYING WARPS OR YARNS OF
COTTON OR OTHER FIBROUS SUBSTANOES."
Sealed the 17th October 1868, and dated the 22nd April 1868.
PROVISIONAL SPECIFICATION left by the said Joseph Holroyd Bolton
at the Office of the Commissioners of Patents, with his Petition,
on the 22nd April 1868.
I, JOSEPH HOLROYD BOLTON, of Manchester, in the County of
Lancaster, do hereby declare the nature of. the said Invention for
"CERTAIN IMPROVEMENTS IN MACHINERY OR APPARATUS FOR SIZEING AND DRYING
WARPS OR YARNS OF COTTON OR OTHER
OTHER FIBROUS SUBSTANCES," to be as
follows:-
My Invention is designed for the purpose of sizeing and drying
or yarns by one continuous process, and also relates to
warps

page_text: improvements upon certain apparatus described in the Specification of
Letters Patent dated March 29, 1865, No. 889.
The improvements consist, first, in combining any of the well-known
machines for sizeing with the drying apparatus described in the Specifi-
cation of the above-named Letters Patent, and arranged so that as soon
as the warps issue from the sizeing apparatus they pass into the drying
apparatus where they are distended round revolving rollers and con-
tinually progress until they pass out therefrom in a dry state, after
which they may be made up into "balls" or other required form, a
series of tension rods, conveying and delivery rollers, and other connected
apparatus being applied between the sizeing and drying apparatus in
order to adapt one machine to the other.
Secondly. The Invention consists in constructing the rollers employed
in such drying machines of an increased diameter to those hitherto
employed in order to take the warp more rapidly from the sizeing
machine, and in applying brushes in suitable positions to each or any
roller or to the ribs or "lags" to cleanse them from the size conveyed
by the yarn and to prevent its accumulation, and at about the middle
of the space between the upper rollers steadying bars or rods are
placed against which the yarn bears to prevent its lateral undulation
and thereby to keep one part out of contact with the other during its
passage.

page_text: that I, the said Joseph Holroyd Bolton, my executors, administrators,
and assigns, or such others as I, the said Joseph Holroyd Bolton, 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
"CERTAIN IMPROVEMENTS IN MACHINERY OR APPARATUS FOR SIZING AND DRYING
WARPS OR YARNS OF COTTON OR OTHER FIBROUS SUBSTANCES," upon the con-
dition (amongst others) that I, the said Joseph Holroyd Bolton, 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 Joseph Holroyd Bolton, 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 and accompanying Drawings (that
is to say):
My Invention is designed for the purpose of sizing and drying
warps or yarns by one continuous process, and also relates to improve-
ments upon certain apparatus described in Specification of Letters
Patent dated March 29, 1865, No. 889.
The improvements consist, first, in combining any of the well-known
machines for sizing with the drying apparatus described in the above
recited Letters Patent, and arranged so that as soon as the warps issue
from the sizing apparatus they pass into the drying apparatus where
they are distended round revolving rollers and continually progress
until they pass out therefrom in a dry state, after which they may be
made up into balls or other required form, a series of tension rods
conveying and delivery rollers and other connected apparatus being
applied between the sizing and drying apparatus in order to adapt the
machine to the other.
Secondly. The Invention consists in constructing the rollers employed
n such drying machines of an increased diameter to those hitherto

page_text: employed in order to take the warp more rapidly from the sizing
machine, and in applying brushes in suitable position to each or any
roller or to the ribs or "lags" thereon to cleanse them from the size
conveyed by the yarn and to prevent the accumulation and at about
the middle of the space between the upper rollers steadying bars or
rods are placed against which the yarn bears to prevent its lateral
undulation and thereby to keep one part out of contact with the other
during its passage.
In order that the Invention may be better understood and explained
in detail, I have hereunto attached a Sheet of Drawings illustrative of
same.
Fig. 1 represents a sectional elevation of the building and apparatus
contained therein employed for sizing and drying warps. In this
Figure a is the sizing trough from which the sized yarn issues and
from whence it is received by the guide rollers b, b, and passed
into the drying room or chamber c in the direction of the arrows in
this room, the yarn in its traverse is distended around the carrier
roller d, d, and around which they progress until they pass out or are
delivered from the drying chamber at the point d' in a dry state, in
which state they may be made up into balls or into other required
shapes. The rollers d, d, employed inside the heating chamber c and
around which the sized yarn is distended, are of an increased diameter
to those usually employed, by which means the warps are caused to
traverse more quickly from the sizing trough or apparatus a, the
projecting lags or ribs of the rollers d, d, are constantly, cleaned of the
size left by the yarn by means of the brushes e, e, also placed in an
intermediate position between the top and bottom rollers, steadying
bars or rods f, f, are placed against which the yarn bears so as to
prevent its lateral undulation, and thereby to keep one part out of
contact with the other during its passage. The apparatus is capable of
being adapted to any class of machine, whether " tape legs," slashers,
or other independent sizing trough.
Having now described the nature of the said Invention, together with
the method of carrying the same into practical effect, I wish it to be
distinctly understood that I claim the adaptation, employment, and use
of a novel arrangement of drying chamber, distending rollers, brushes,
and tension bars herein-before described, or any slight modification
thereof to "tape legs," slashers, or independent sizing troughs for drying

page_text: yarn, as herein-before described, set forth, and fully illustrated in the
Drawings attached.
In witness whereof, I, the said Joseph Holroyd Bolton, have
hereunto set my hand and seal, this Twentieth day of October,
in the year of our Lord One thousand eight hundred and sixty-
eight
JOSEPH HOLROYD BOLTON. (L.S.)
