IMPROVEMENTS IN MACHINERY FOR CARDING FIBRES
Year: 1879

page_text: LETTERS PATENT to James Schofield, Cotton Manufacturer, James Walton,
Manager, and Thomas Holt, Carder, all of Littleborough, in the County of
Lancaster, for the Invention of "IMPROVEMENTS IN MACHINERY FOR CARDING
FIBRES"
PROVISIONAL SPECIFICATION left by the said James Schofield, James
Walton, and Thomas Holt at the Office of the Commissioners of Patents on the
20th January 1879.
JAMES SCHOFIELD, Cotton Manufacturer, JAMES WALTON, Manager, and THOMAS
HOLT, Carder, all of Littleborough, in the County of Lancaster. IMPROVEMENTS
IN MACHINERY FOR CARDING FIBRES."
This Invention relates to an improved construction of stripping roller for carding
engines, the object being to ensure the stripping of the cylinder, and also the
self cleansing or clearing of the said roller.
Stripping rollers according to this our said Invention comprise a roller having
a recess or groove cut or formed along its periphery either parallel to the axis,
or such groove or recess is cut or formed spirally around the said roller.
Within the groove or recess is secured a row or rows of steel pins, the latter
being "set" or affixed in india rubber or other material. The pins being of such
length as to slightly protrude out of the recess and beyond the circumference of
the roller, so as to engage with the cards of the cylinder, swift or other card
covered roller in connection with which the improved roller may be used.
By means of the recessing or grooving we are enabled to employ pins of con-
siderable length, so as to secure elasticity or freedom from stiffness or rigidness
of the pins, and whilst employing long pins a freedom from the paring action
inseparable from use of cards of considerable length when applied to the circum-
ference of the roller as heretofore, and the use of straight pins also ensures through
the rapid rotation of the roller the self cleansing of such pins from fibre. The
use of the improved roller above described obviates or effects great saving in
the labour of hand cleaning or "fettling" the cards.

"IMPROVEMENTS
IN MACHINERY FOR CARDING FIBRES."
This Invention relates to an improved construction of stripping roller for carding
engines, the object being to ensure the stripping of the cylinder, and also the self
cleansing or clearing of the said roller.
Stripping rollers according to this our said Invention comprise a roller having a
recess or groove cut or formed along its periphery, either parallel to the axis, or
such groove or recess is cut or formed spirally around the said roller.
"
Within the groove or recess is secured a row or rows of steel pins, the latter
being "set or affixed in india rubber or other material, the pins being of Buch
length as to slightly protrude out of the recess and beyond the circumference of the
roller, so as to engage with the cards of the cylinder, swift, or other card covered
roller in connection with which the improved roller may be used. By means of the
recessing or grooving we are enabled to employ pins of considerable length, so as to
secure elasticity or freedom from stiffness or rigidness of the pins, and whilst
employing long pins a freedom from the fanning action inseparablo from use of
cards of considerable length, when applied to the circumference of the roller as
heretofore, and the use of straight pins also ensures through the rapid rotation of
the roller the self cleansing of such pins from fibre.
The use of the improved roller above described obviates or effects great saving
in the labour of hand cleaning or "fettling" the cards, and prevents the continual
stopping of the engines to strip, produces even weight of sliver, and increases
production.
Such being the nature and object of this our said Invention, in order that the
same may be fully understood we have hereunto annexed two Sheets of Drawings

page_text: connection with which the improved stripping roller herein described is used. In
some cases it may be advantageous to use more than one groove and strip of cards,
but ordinary we find one groove and one strip sufficient.
Having thus fully described the nature and particulars of this our said Invention,
together with the manner in which the same is to be or may be performed or
carried into practical effect, we would have it understood that we claim as our
Invention,-
The construction and use of rollers having recess B and pins D, in manner and
for purpose described, and substantially as illustrated by Drawings.
In witness whereof, we, the said James Schofield, James Walton, and Thomas
Holt, have hereunto set our hands and seals, this Sixteenth day of July,
in the year of our Lord One thousand eight hundred and seventy nine.
Witness to all three signatures,
A. H. SCHOFIELD,
