Year: 1860

page_text: LETTERS PATENT to Edward Barlow, of Bolton-le-Moors, in the County
of Lancaster, Machine Maker, James Newhouse, of Farnworth, in the
same County, Manager, and Francis Hamilton, of Bolton-le-Moors,
aforesaid, Foreman, for the Invention of "CERTAIN IMPROVEMENTS IN
MACHINERY FOR CARDING COTTON AND OTHER FIBROUS SUBSTANCES.
PROVISIONAL SPECIFICATION left by the said Edward Barlow, James
Newhouse, and Francis Hamilton at the Office of the Commissioners of
Patents, with their Petition, on the 17th December 1860.
We, EDWARD BARLOW, of Bolton-le-Moors, in the County of Lancaster,
Machine Maker, JAMES NEWHOUSE, of Farnworth, in the same County,
Manager, and FRANCIS HAMILTON, of Bolton-le-Moors, aforesaid, Foreman,
do hereby declare the nature of the said Invention for "CERTAIN IMPROVE-
MENTS IN MACHINERY FOR CARDING COTTON AND OTHER FIBROUS SUBSTANCES," to be
as follows:-
Our Invention consists, first, in certain improved arrangements of rollers
covered with card teeth acting in combination with each other, and with the
main cylinder for cleaning the fibrous substances, and for stripping the main
cylinder. In performing this part of our Invention we employ two rollers
working above the licker-in, and with each other, for the purpose of opening
and preparing the cotton or other fibrous substances preparatory to carding
with the ordinary working rollers or flats; the first roller works in combination

page_text: with the upper surface of the licker-in with the main cylinder, and with the
second roller; the second roller is set to the first roller and to the main
cylinder; this second roller performs the operation of carding with the main
cylinder, and at the same time takes off any proportion of fibrous substances,
and gives it back to the first roller, and the first roller delivers it again to the
licker-in, thereby rendering it impossible for any flakes of fibrous material to
escape to the working rollers or flats. We wish it to be understood that by
changing the speed of the rollers the quantity of fibrous material taken from
the main cylinder and delivered again to the licker-in may be varied, and we
would also observe, that although we have described two rollers acting in
combination with each other and with the main cylinder and licker-in, it may
be found desirable in some cases to use only one, or more than two such
rollers.
The second part of our Invention relates to the machinery, for which Letters
Patent were granted to Henry Bernoulli Barlow, on the Twenty-ninth day of
December, One thousand eight hundred and fifty-nine, No. 2971, and consists
in making the teeth of the stripping roller described in the Specification of the
said Letters Patent to penetrate at intervals between the teeth of the main
cylinder, by which means the stripping roller is also made to clean or remove
the dirt from the main cylinder.
SPECIFICATION filed in pursuance of the conditions of the Letters Patent,
and of an Order of the Lord Chancellor, by the said Edward Barlow,
James Newhouse, and Francis Hamilton, in the Great Seal Patent
Office on the 11th July 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, wc, EDWARD
BARLOW, of Bolton-le-Moors, in the County of Lancaster, Machine Maker,
JAMES NEWHOUSE, of Farnworth, in the same County, Manager, and FRANCIS
HAMILTON, of Bolton-le-Moors, aforesaid, Foreman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventeenth day of December, in the year of our
Lord One thousand eight hundred and sixty, in the twenty-fourth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said Edward Barlow, James Newhouse, and Francis Hamilton, Her
special licence that we, the said Edward Barlow, James Newhouse, and
Francis Hamilton, our executors, administrators, and assigns, or such others
as we, the said Edward Barlow, James Newhouse, and Francis Hamilton,

page_text: our 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 FOR CARDING COTTON AND OTHER FIBROUS SUBSTANCES," upon the con-
dition (amongst others) that we, the said Edward Barlow, James Newhouse,
and Francis Hamilton, 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 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 we, the said Edward Barlow, James Newhouse,
and Francis Hamilton, 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 (that is to say):―
Our Invention consists in certain improved arrangements of rollers, covered
with card teeth, acting in combination with each other, and with the main
cylinder for cleaning the fibrous substances.
In performing our Invention, we employ two rollers working above the
licker-in and with each other, for the purpose of opening and preparing the
cotton or other fibrous substances preparatory to carding with the ordinary
working rollers or flats. The first roller works in combination with the upper
surface of the licker-in, with the main cylinder, and with the second roller;
the second roller is set to the first roller and to the main cylinder. This
second roller performs the operation of carding with the main cylinder, and
at the same time takes off any proportion of fibrous substances, and gives it
back to the first roller, and the first roller delivers it again to the licker-in,
thereby rendering it impossible for any flakes of fibrous material to escape to
the working rollers or flats.
We wish it to be understood, that by changing the relative speed of the
rollers, the quantity of fibrous material taken from the main cylinder, and
delivered again to the licker-in may be varied; and we would also observe,
that although we have described two rollers acting in combination with each
other, and with the main cylinder and licker-in, it may be found desirable in
some cases to use more than two such rollers.
And in order that our Invention may be fully understood and readily
carried into effect, we will proceed to describe the accompanying Drawing,

page_text: which represents the principal parts of a carding engine to which our
improvements are applied. a, a, are the feed rollers; b, the licker-in; c, the
main cylinder; d, d, the workers and clearers; and e, the doffer. In some
cases top flats may be used, instead of or combined with workers and clearers.
These parts, and all the others which are requisite to complete the carding
engine, but which are not shewn on. the Drawing, or not particularly referred
to hereafter, are made in the usual manner.
Our improvements consist in applying to a carding engine the two rollers
covered with card teeth, marked f and g, both of which are mounted in
adjustable bearings attached to the framing of the engine. The roller f works
in combination with the upper surface of the licker-in and with the main
cylinder. This roller revolves, and the card teeth are set in the same direction
as the licker-in, but the surface of the licker-in moves at a greater velocity
than that of the roller f. The roller g works in combination with the upper
surface of the roller f and with the main cylinder; this roller revolves much
slower, but in the same direction as the roller f, and the card teeth of the
roller g point in the contrary direction to those of the roller f.
The pulleys, straps, and chains shown on the Drawing indicate a convenient
mode of transmitting motion to the rollers ƒ and g when they are applied to a
carding engine for operating upon cotton. To the axle of the main cylinder c
is fixed a pulley c¹, which by means of the crossed strap h, passing around the
pulleys f' and ', gives the requisite rotary motion to the roller f and to the
licker-in b, while the slow rotary motion of the roller g is imparted by
the chain i, which drives the working rollers d in the usual manner. We
wish it, however, to be understood that the rollers ƒ and g may be driven in
any other convenient manner, and the relative velocities of the rollers as
indicated by the pulleys may be considerably varied.
When the carding engine is at work the fibrous material is delivered to the
main cylinder by the licker-in as usual, but the fibres carried by the licker-in
beyond the main cylinder are stripped off by the roller f, and delivered to the
main cylinder. The fibres are carded between the main cylinder and the
roller g, which is stripped by the roller f, and delivers the fibres to the licker-
in. By varying the set of the roller g with respect to the main cylinder, a
greater or less quantity of the fibrous substances is taken hold of by the roller g,
and delivered to the roller f, as above described.
We would also observe, that although we have shewn and described two
rollers acting in combination with each other, and with the main cylinder and
licker-in, it may be found desirable in some cases to apply more than two such
rollers, that is to say, a third roller may be applied above the roller g.

page_text: By means of these improvements the fibrous substances are effectually
opened and partially carded before they are carried forward by the main
cylinder to the workers and clearers or to the top flats, thus preventing any
flakes of fibres escaping to the working rollers or flats.
Having thus described the nature of our Invention, and the manner of
performing the same, we declare that we claim the rollers ƒ and g when
applied to carding engines in the manner and for the purposes described, and
we also claim, as a modification of our Invention, the application of more
than two rollers, as described.
In witness whereof, we, the said Edward Barlow, James Newhouse,
and Francis Hamilton, have hereunto set our hands and seals, this
First day of July, in the year of our Lord One thousand eight hundred
and sixty-one.
