Year: 1865

page_text: LETTERS PATENT to John Gaukroger, of Hebden Bridge, in the County
of York, Cotton Spinner and Manufacturer, and John Dodgeon, of
Burnley, in the County of Lancaster, Commission Agent, for the Inven-
tion of "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR SIZING, DRYING,
AND BEAMING YARNS OF COTTON OR OTHER FIBROUS SUBSTANCES."
Sealed the 2nd February 1866, and dated the 4th August 1865.
PROVISIONAL SPECIFICATION left by the said John Gaukroger and
John Dodgeon at the Office of the Commissioners of Patents, with their
Petition, on the 4th August 1865.
We, JOHN GAUKROGER, of Hebden Bridge, in the County of York, Cotton
Spinner and Manufacturer, and JOHN DODGEON, of Burnley, in the County of
Lancaster, Commission Agent, do hereby declare the nature of the said Inven-
tion for "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR SIZING, DRYING, AND
BEAMING YARNS OF COTTON OR OTHER FIBROUS SUBSTANCES," to be as follows:-
This Invention relates to the machine commonly called "slasher," and the
improvements consist, firstly, in the employment of one or more winged,
ribbed, grooved, or perforated rollers for conducting the yarns through the
Sizing trough instead of the plain surfaced rollers now used for that purpose,

page_text: by which means the size is better enabled to penetrate the yarns. Also in the
nse of three or more plain rollers for the same purpose, whereby the yarns
are longer immersed in the size than heretofore.
Secondly, the improvements consist in applying an eccentric or crank on
the nipping roller, which is in contact with the measuring roller, and having
a rod attached thereto, and to a lever and catch or ratchet for actuating the
ordinary ratchet wheel, which is fixed on the traverse sciew of the taper or
comeal drums for traversing the strap guide thereon, whereby the speed or
taking up of the yarn beam is regulated by the speed of the drying cylinders,
which are duiven at a uniform speed, and consequently we obtain regularity
in the diying.
Thirdly, in applying a friction pulley with a lever and an adjustable weight
to the aforesaid nipping roller for producing tension on the yarn during the
winding on to the beam, instead of weighting the back yarn beams, whereby
stretching of the yarn is avoided.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Gaukroger and John Dodgeon in the Great Seal Patent
Office on the 3rd February 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
GAUKROGER, of Hebden Bridge, in the County of York, Cotton Spinner and
Manufacturer, and JOHN DODGEON, of Burnley, in the County of Lancaster,
Commission Agent, send greeting.
WHEREAS Пler most Excellent Majesty Queen Victoria, by Пer Letters
Patent, bearing date the Fourth day of August, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-ninth year of Her

the said John Gaukroger and John Dodgeon, Her special licence, that we,
the said John Gaukroger and John Dodgeon, our executors, administrators,
and assigns, or such others as we, the said John Gaukroger and John
Dodgeon, our executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times there-
after 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 "IMPROVE-
MENTS IN MACHINERY OR APPARATUS FOR SIZING, DRYING, AND BEAMING YARNS OF
COTTON OR OTHER FIBROUS SUBSTANCES," upon the condition (amongst others)

page_text: that we, the said John Gaukroger and John Dodgeon, 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 per-
formed, 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 John Gaukroger and John Dodgeon,
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 and accompanying Sheet of Drawings (that
is to say)-
This Invention relates to the machine commonly called "slasher," and the
improvements consist, firstly, in the employment of one or more winged,
ribbed, grooved, or perforated rollers for conducting the yarns through the
sizing trough instead of the plain surfaced rollers now used for that purpose,
by which the size is better enabled to penetrate the yarns
Also in the use
of three or more plain rollers for the same purpose, whereby the yarns are
longer immersed in the size than heretofore.
Secondly, the improvements consist in applying an eccentric or crank on
the nipping roller, which is in contact with the measuring rollers with a rod
attached thereto, and to a lever and catch for actuating the ordinary ratchet
wheel, which is fixed on the traverse screw, or the screw employed to operate
the strap guide for traversing the strap on the conical or taper diums.
Thirdly, in applying a fiction pulley with a lever and an adjustable weight
to the aforesaid nipping roller for producing the necessary tension on the
yarn dung the winding on to the beam, instead of weighting the back yarn
beams, whereby stretching of the yarn is avoided.
DESCRIPTION OF THE DRAWINGS
Fig. 1 is a longitudinal elevation of a "slasher" or sizing machine with our
improvements applied thereto. The puncipal parts of this machine being
so well known and understood it is not necessary to describe them all in detail,
suffice it that A are yarn beams; B, the sizing trough; C, the drying cylin-
ders; D, the measuring rollers, E, the nipping roller in contact therewith;
F, the traverse screw; and G, the taper or conical drums.
The fust part of our improvements are shewa by the circles at B, repre-
senting thee olleis for conducting the yarn through the sizing trough, which
rollers are also shewn half full size in cross section in Fig. 2. These rollers

page_text: are constructed of two end discs H, keyed on a shaft, and a series of round
bais on rods I, fixed between with one or more intermediate discs as bearings
or supports. They are mounted in slide frames J, so as to be capable of
adjustment according to the depth or quantity of size liquor in the trough in
the usual manner. The dotted line shews the course of the yarns through
the trough, by which it will be seen that the said yarns are immersed in the
size liquor from their entrance to their exit from the trough, and yet kept
separate from each other by contact with the rollers, so that they are not
blown about by the boiling liquor fastening them together in bands, as is the
case when unsupported; and it will be observed that by this form of roller
the size liquor can get equally to all sides of the yarn, or around each thread,
and the great length of time or distance of travel during immersion enables
the size liquor to penetrate, and therefore become more securely fixed in or
on the yarns
It will be evident that these rollers may be constructed of a
series of wings or ribs, or they may be grooved longitudinally or fluted, or may
be perforated surfaces, so as to allow the size liquor to pass around the yarn
or threads. Also it will be readily understood that three plain rollers may be
ananged in this manner for conducting yarns through sizing troughs, by which
a greater extent or a longer time of immersion is given than heretofore, and
yet the yarn is supported all the while. Or one large roller of sufficient dia-
meter to fill up the whole width of the sizing trough may be employed, in
order to obtain a greater amount of immersion of the yain in the liquor, but
the yarns having to lay on a solid surface, it is clear they cannot become so
thoroughly saturated with the liquor as when laid on the surface of rollers
constructed as herein-before described.
The second part of our Invention is shewn applied by letters K, which is an
eccentric fixed on the nipping roller and a rod L connected thereto, and to a
lever M, to which lover is also hinged a catch N, taking into the ordinary
ratchet wheel of the traverse sciew. This apparatus is more clearly seen in
detail at Fig 3, where it will be observed that there are two slots in the lever,
so that the studs, to which the rod and the catch are attached, may be set so
as to produce any desirable amount of throw or motion of the
at each stroke, yet without altering or changing the eccentric.
eccentric a crank may be used for this purpose.

Instead of an
The third part of this Invention is shewn at P, which is a lever with an
adjustable weight hinged to the frame at R, having a strap S attached thereto,
which passes around a friction pulley T fixed on the nipping roller. This
apparatus is also shewn in detail at Fig. 4, and the action of which in retaid-
ing the rotation of the nipping roller, and others in connection therewith, will

page_text: be easily understood. By means of this improvement a proper tension is
effected on the yarn without any undue stretching thereof as heretofore.
In witness whereof, I, the said John Dodgeon, for and on behalf of
myself and the said John Gaukroger, have hereunto set my hand and
seal, this Fust day of February, One thousand eight hundred and
sixty-six.
