IMPROVEMENTS IN SPINNING COTTON AND OTHER FIBROUS MATERIALS
Year: 1850

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
BERNOULLI BARLOW, of Manchester, in the County of Lancaster, Consulting.
Engineer and Patent Agent, send greeting.
WHEREAS in consequence of a communication made to me by Mr. Motte-
Bossut, of Roubaix, in the Republic of France, Cotton Spinner, who was and.
is a foreigner: residing abroad, I became and am in possession of an Inven-.
tion for IMPROVEMENTS IN SPINNING COTTON AND OTHER FIBROUS MATERIALS:"
And whereas Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent, under the Great Seal of the United Kingdom of Great Britain
and Ireland, bearing date at Westminster, the Seventeenth day of October now
last past, did, for Herself, Her heirs, and successors, give and grant unto me,
the said, Henry Bernoulli Barlow, my exors, admors, and assigns, Her especial
license, that I, the said Henry Bernoulli Barlow, my exors, adñiors, and
assigns, or such others as I, the said Henry Bernoulli Barlow, my exors,
adiñors, and assigns, should at any time agree with, and no others, from time
to time and at all times during the term of years therein expressed, should and
lawfully might make, use, exercise, and vend, within England, Wales, and the
Town of Berwick-upon-Tweed, the said Invention; in which said Letters Patent
is contained a proviso, obliging me, the said Henry Bernoulli Barlow, by an
instrument in writing under my hand and seal, particularly to describe and
ascertain the nature of the said Invention, and in what manner the same is to be
performed, and to cause the same to be enrolled in Her said Majesty's High

page_text: Court of Chancery within six calendar months next and immediately after the
date of the said récited Letters Patent, as in and by the said Letters Patent,
reference being thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Henry Bernoulli Barlow, hereby declare the nature of the said Invention to
consist in applying water or other suitable liquid to the front drawing roller, or
to a callender roller in front of the front drawing roller of machines for spinning
cotton and similar fibrous materials, for the purpose of moistening the roving
under operation, after it has been stretched and before the twist for converting
the roving into yarn is given; and in order that my Invention may be fully
understood and readily carried into effect, I will proceed to describe the
accompanying Drawing, in which Fig. 1 represents a sectional elevation of
part of a machine for spinning, commonly called a throstle; a is the back
drawing roller; b, the middle drawing roller, and c the front drawing roller,
which is made of brass or other metal that will not corrode by the action of
water. The rollers a and b are provided with top rollers d and e of the
ordinary construction, but the top roller f must be covered with vulcanized
india-rubber, or any other suitable material that will not be injuriously acted
upon by moisture; g is a trough placed under the front roller c, and
containing water or other suitable liquid for 'wetting the roving after it has
been stretched by the drawing rollers, and before it is spun 'and wound on to
the bobbin h. By this means of applying the moisture, it is evident that the
process of stretching or drawing between the sets of drawing rollers is
performed while the roving is dry, and the moisture is only given at the
moment the roving is passing between the rollers c and f; from this it will be
apparent that such injurious effects as arise from drawing or stretching a
roving after it is wet are completely prevented. Another mode of effecting
the same object is represented in Fig. 2, in which view the drawing rollers
i, i, i, and top rollers j, j, j, are precisely similar to those in ordinary use; in
front of these is the calendar roller-k, the surface of which moves at the same
velocity as the surface of the front drawing roller; is the top roller of the
calender 'roller k, 'to which pressure is given by a weighted saddle, in reaching
from the top roller of the front drawing roller, 'or in any other convenient
way; n is the trough containing water or other liquid placed under the
calender roller k. By this arrangement the moisture is given to the fibres
under operation after the process of drawing is completed; consequently, there
is less danger of the fibres adhering to and lapping round the front drawing
roller than when the moisture is applied to the front drawing roller. After
the rovings have been acted upon by cither of the above described processes,

page_text: the loose fibres, which in spinning dry rovings project from the yarn, are
incorporated in it, and render the yarn more even and strong, and consequently
better fitted for doubling and other subsequent operations.
Having now described the nature and particulars of the said Invention, I
wish it to be understood that I do not claim any of the parts separately, but
I do claim the combination and arrangement of drawing and calender rollers
with the trough containing the water or other fluid, as herein before described,
and shewn in the annexed drawings when applied to machinery for spinning
cotton and similar fibrous materials. And this my Invention being to
the best of my knowledge and belief entirely new, and never before used
within that part of Her said Majesty's United Kingdom of Great Britain and
Ireland called England, Her Dominion of Wales, and Town of Berwick upon
Tweed, I do hereby declare this to be my Specification of the same, and
that I do verily believe this my said Specification doth comply in all respects,
fully and without reserve or disguise, with the proviso in the said herein-
before in part recited Letters Patent contained. Wherefore, I do hereby
claim to maintain exclusive right and privilege to the said Invention.
In witness whereof, I, the said Henry Bernoulli Barlow, have hereunto
set my hand and seal, this Fifteenth day of April, in the year of our
Lord One thousand eight hundred and fifty-one.
HENRY BERNOULLI (L.s.) BARLOW.
AND BE IT REMEMBERED, that on the Fifteenth day of April, in the
year of our Lord 1851, the aforesaid Henry Bernoulli Barlow came before our
said Lady the Queen in Her Chancery, and acknowledged the Specification
aforesaid, and all and every thing therein contained and specified, in form
above written. And also the Specification aforesaid was stamped according
to the tenor of the Statute made for that purpose.
Enrolled the Sixteenth day of April, in the year our Lord One
thousand eight hundred and fifty-one.
