page_text: LETTERS PATENT to George Young, Manager for Messieurs James Burton and .
Sons, of Tyldesley, in the County of Lancaster, for the Invention of "IMPROVE-

AND OTHER FIBROUS SUBSTANCES.”
ealed the 9th April 1878, and dated the 13th October 1877.
PROVISIONAL SPECIFICATION left by the said George Young at the
Office of the Commissioners of Patents on the 13th October 1877.
GEORGE YOUNG, Manager for Messieurs James Burton and Sons, of Tyldesley, in
the County of Lancaster. "IMPROVEMENTS IN THE CONSTRUCTION OF MACHINES
USED FOR OPENING COTTON AND OTHER FIBROUS SUBSTANCES.'
This Invention relates to the construction of the machine called the "opener,"
used for opening or loosening the raw cotton or other fibrous substance, and forming
it into a "lap," to be fed into the carding engine, the object of the said Invention
being to dispense with the "beater" in such machines, and thus to decrease both
the bulk and cost of the machine.
"
"
In these machines the cotton or other fibrous substance is spread upon a creeper
or endless travelling apron, from which it is taken by a pair of feeding rollers and
'porcupine
delivered by the latter to a roller provided with teeth, and called the "
roller," from which it then proceeds to a beater, which latter throws it on to the
revolving cage which forms the "lap."
The "porcupine roller" as now constructed consists of a cylinder provided with
teeth or projections, and serves principally to take the cotton or other fibres from
the feeding rollers, and deliver them to the "beater;" but according to my Inven-
tion I make the porcupine roller in such a way that it serves also as a "beater,"
and delivers the fibres direct on to the cage, and I thus dispense entirely with the
ordinary beater.
Instead of making the porcupine roller in the form of a cylinder, as hitherto, I
make it as follows-Upon a central shaft I key a suitable number of bosses (say
To the end of these radial
four), each provided with two or more radial arms.
arms are fixed longitudinal bars or rails, parallel to the central axis, thus forming a

page_text: kind of skeleton roller, somewhat like a beater. Upon the longitudinal bars or
rails I now fix the series of porcupine teeth, and the skeleton roller then becomes a
combined "porcupine" and "beater." This is placed immediately behind the
feeding rollers, and in juxtaposition to the cage (the ordinary "beater" being
dispensed with), and it opens and beats the cotton or other fibrous substance, and
throws it direct on to the perforated " cage."
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said George Young in the Great Seal Patent Office on the 11th April
1878.
GEORGE YOUNG, Manager for Messieurs James Burton and Sons, of Tyldesley, in
the County of Lancaster. "IMPROVEMENTS IN THE CONSTRUCTION OF MACHINES USED

it into a "lap," to be fed into the carding engine, the object of the said Invention
being to dispense with the "beater" in such machines, and thus to decrease both
the bulk and cost of the machine.
Such being the nature and object of my said Invention, I will now proceed to
describe in detail the manner in which the same is to be or may be performed or
carried into practical effect; and in order that the same may be clearly understood
I have annexed hereunto a Sheet of Drawing illustrative thereof, and have marked
the same with figures and letters of reference, corresponding with those in the
following explanation thereof.

In these machines the cotton or other fibrous substance is spread upon a "creeper
or endless travelling apron, from which it is taken by a pair of feeding rollers, and
delivered by the latter to a roller provided with teeth, and called the "porcupine
roller," from which it then proceeds to a beater, which latter throws it on to the
revolving cage, which forms the "lap."
The porcupine roller as now constructed consists of a cylinder provided with
teeth or projections, and serves principally to take the cotton or other fibres from
the feeding rollers and deliver them to the "beater;" but according to my Inven-
tion make the porcupine roller in such a way that it serves also as a
"beater,"
and delivers the fibres direct on to the cage, and I thus dispense entirely with the
ordinary beater.
Fig. 1 in the annexed Drawing is an end view, and Fig. 2 a side view of a com-
bined "porcupine" roller and beater, made according to my Invention.
Instead of making the porcupine roller in the form of a cylinder, as hitherto, I
make it as follows:-Upon a central shaft a, a, I key a suitable number of bosses
b, b, (say four,) each provided with two or more radial arms c, c. To the ends of
these radial arms are fixed longitudinal bars or rails d, d, parallel to the central
axis a, a, thus forming a kind of skeleton roller, somewhat like a beater. Upon
the longitudinal bars or rails d, d, I now fix the series of porcupine teeth e, e, or

page_text: they may be cast in one piece with the bar, as shown in the Drawing, and the
skeleton roller then becomes a combined "porcupine" and "beater." This is placed
immediately behind the feeding rollers, and in juxtaposition to the cage (the
ordinary "beater " being dispensed with), and it opens and beats the cotton or other
fibrous substance, and throws it direct on to the perforated "cage."
Having now described the nature and object of my said Invention, together with
the manner in which the same is to be or may be performed or carried into practical
effect, I wish it to be understood that I claim as my Invention, the construction
and use of a combined "porcupine" roller and beater, substantially in the manner
and for the purposes herein-before particularly set forth, and illustrated by the
Drawings annexed.
In witness whereof, I, the said George Young, have hereunto set my hand
and seal, this Ninth day of April, in the year of our Lord One thousand
eight hundred and seventy-eight.
