Year: 1878

page_text: LETTERS PATENT to William Henry Oates, of Shaw, near Oldham, in the
County of Lancaster, and Charles Pearson, of Miles Platting, in the same
County, both in the employ of Messrs. Evan Leigh, Son, and Company,
Limited, Miles Platting, as aforesaid, for the Invention of IMPROVEMENTS
IN OR APPLICABLE TO CARDING ENGINES."
Sealed the 22nd October 1878, and dated the 24th April 1878.
PROVISIONAL SPECIFICATION left by the said William Henry Oates. and
Charles Pearson at the Office of the Commissioners of Patents on the 24th
April 1878.
WILLIAM HENRY. OATES, of Shaw, near Oldham, in the County of Lancaster,
and CHARLES PEARSON, of Miles Platting, in the same County, both in the employ.
of Messrs. Evan Leigh, Son, and Company, Limited, Miles Platting, as aforesaid.
"IMPROVEMENTS IN OR APPLICABLE TO CARDING ENGINES."
Our Invention consists in applying a roller at the back or other suitable position
around the main cylinder, by preference near the "taker in," running in the
contrary direction to the main cylinder and in contact therewith, and at or about
the same surface speed. We prefer to cover this roller with a flat, short, and clear
cut wire card.
We have found that a roller operating upon the main cylinder as described has
the effect of clearing the card of all seeds and fibres as it comes from the doffing
cylinder, and that its application obviates the necessity which now exists of
frequently stopping for the purpose of stripping the main cylinder, and saves the
time and expense heretofore rendered necessary by such frequent stripping.
The card is also cleaner and better prepared for receiving the fresh cotton or other
fibre at the "taker in," whilst a cylinder so cleared, as aforesaid, will card an
increased quantity of fibrous material in a given time.

Office on the 24th October 1878.
WILLIAM HENRY OATES, of Shaw, near Oldham, in the County of Lancaster,
and CHARLES PEARSON, of Miles Platting, in the same County, both in the employ of
Messrs. Evan Leigh, Son, & Co., Limited, Miles Platting, as aforesaid. " IMPROVE-
MENTS IN OR APPLICABLE TO CARDING ENGINES."
Fig. 1 representing a side sectional view, and Fig. 2 an exterior side view of so
much of a carding engine as is necessary to illustrate our improvements, which are
shewn applied thereto.
In both views A is the main cylinder mounted in the usual manner in the frame-
work B, and C is the "taker in."
"
Our Invention consists in applying the roller D at the back of the main cylinder
in adjustable bearings E, by preference near the 'taker in" C, as illustrated; this
roller D is covered with a flat, short, and clear cut wire card, or with what is known
as a "saw tooth" card, and is driven at or about the same surface speed as the main
cylinder, but in a contrary direction, and as near as possible thereto without actually
touching. The object of this roller D, which is self stripping, owing to the nature of
its covering, is to clear the cylinder of all seeds and fibres as they come from the
doffing cylinder, and its application obviates the necessity which now exists of
frequently stopping the engine for the purpose of stripping the main cylinder,
and saves the time and expense heretofore rendered necessary by such frequent
stripping.
The card surface of the main cylinder is also cleaner and better prepared for
receiving the fresh cotton or other fibre at the "taker in," whilst a cylinder so
cleared as aforesaid will card an increased quantity of fibrous material in a given
time, and in a more perfect manner.
Although we have shewn the roller D as applied near the "taker in" we wish it
to be distinctly understood that a somewhat similar effect would be produced by
applying such roller when covered as aforesaid in any position underneath the main
cylinder, and therefore we do not confine ourselves to the position indicated upon
the Drawing.
Having thus particularly described and ascertained the nature of this our said
Invention, together with the best methods with which we are acquainted for carrying
the same into practical effect, we wish it to be understood that we claim, the
use and application of the roller D when covered, mounted, and operating substan-
tially as and for the purposes herein-before described, and illustrated on the
accompanying Drawing.
In witness whereof, we, the said William Henry Oates and Charles Pearson,
have hereunto set our hands and seals, this 23rd day of October, in the
year of our Lord One thousand eight hundred and seventy-eight.
