IMPROVEMENTS IN MACHINERY FOR PREPARING, SPINNING, TWISTING, AND DOUBLING COTTON AND OTHER FIBROUS MATERIALS
Year: 1870

page_text: LETTERS PATENT to Robert Lakin, of Manchester, in the County of
Lancaster, Machinist, and John Bayley, of Heaton Norris, in the
same County, Mill Manager, for the Invention of "IMPROVEMENTS IN
MACHINERY FOR PREPARING, SPINNING, TWISTING, AND DOUBLING COTTON AND
OTHER FIBROUS MATERIALS."
Sealed the 12th August 1870, and dated the 19th February 1870.

PROVISIONAL SPECIFICATION left by the said Robert Lakin and
John Bayley at the Office of the Commissioners of Patents, with
their Petition, on the 19th February 1870.
We, ROBERT LAKIN, of Manchester, in the County of Lancaster,
Machinist, and JOHN BAYLEY, of Heaton Norris, in the same County,
Mill Manager, do hereby declare the nature of the said Invention for
'IMPROVEMENTS IN MACHINERY FOR PREPARING, SPINNING, TWISTING, AND DOUBLING
COTTON AND OTHER FIBROUS MATERIALS," to be as follows:-
In some of these machines the bobbins are driven positively, in
others they are drawn round by the tension of the material being wound

page_text: thereon, the rotation of the bobbin being partially restrained by a drag.
Our Invention applies to the latter, and relates to an improved mode of
regulating the drag of the bobbins. To effect this we employ two bushes
similar to those described in the Provisional Specification of Letters
Patent applied for by us on the 14th day of September 1869, No. 2680.
Instead, however, of using a stationary spindle and driving the bobbin
positively, as there described, we drive the spindle and flyer in the usual
manner, and we make the inner bush to fit the spindle, which steadics
the spindles as they rotate. The under side of the disc on the inner
tube rests on the top of the outer tube. The bobbin is placed on the
upper portion of the inner tube and rests on a washer placed on the
disc. When the machine is in operation the spindle is driven in the
usual manner, at which time the friction between the spindle and
_the_inner bush tends to cause the bush to rotate, and with it the washer,
thus forming a rotating drag. The speed at which the bush and washer
will be caused to rotate by the rotation of the spindle can easily be
governed by varying the surface of contact between the disc and the
upper surface of the outer tube. The bobbin rotates by the tension of
the material, and as we can vary the rotation of the bush and washer, as
before described, we are enabled to vary the drag to suit the material.
By means of these improvements we can run the spindles at a high
velocity and spin yarn of fine counts.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Robert Lakin and John Bayley in the Great Scal
Patent Office on the 18th August 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, ROBERT
LAKIN, of Manchester, in the County of Lancaster, Machinist, and
JOHN BAYLEY, of Heaton Norris, in the same County, Mill Manager,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Nineteenth day of February, in the
year of our Lord One thousand eight hundred and seventy, in the
thirty-third year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said Robert Lakin and John Bayley, our Her
special licence that we, the said Robert Lakin and John Bayley, our

page_text: executors, administrators, and assigns, or such others as wc, the said
Robert Lakin and John Bayley, 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 “IMPROVEMENTS IN MACHINERY FOR PREPARING,
SPINNING, TWISTING, AND DOUBLING COTTON AND. OTHER FIBROUS MATERIALS,"
upon the condition (amongst others) that we, the said Robert Lakin
and John Bayley, 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 In-
yention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Scal Patent Office within six
calendar months next and immediately after the date of the said
Letters Patent..
NOW KNOW YE; that we, the said Robert Eakin and John Bayley,
do hereby declare the nature of our said Invention, and in what manner
the same is to be performed, to be particularly described. and: ascer-
tained in and by the following statement (that is-to say) :—
In some of these machines. the bobbins are driven. positively, and in
others they are drawn round by the tension of the material being
wound thereon, the rotation of the bobbin being partially restrained
by a drag. Our Invention applies to the latter, and relates to an
improved mode of regulating the drag of the bobbins. To effect this
we employ two bushes similar to those described in the Specification
of Letters Patent granted to us on the Fourteenth day of September
One thousand eight hundred and sixty-nine, Number 2680. Instead,,
however, of using a stationary spindle and driving the bobbin positively, as.
there described, we drive the spindle and flyer in the usual manner and
we make the inner bush to fit the spindle, which steadies the spindles
as they rotate. The under side of the disc on the inner tube rests on
the top of the outer tube. The bobbin is placed on the upper portion
of the inner tube and rests on a washer placed on the disc. When
the machine is in operation the spindle is driven in the usual
manner, at which time the friction between the spindle. and the
inner bush tends to cause the bush to rotate and with it the

page_text: washer, thus forming a rotating drag. The speed at which the bush
and washer will be caused to rotate by the rotation of the spindle can
easily be governed by varying the surface of contact between the disc
and the upper surface of the outer tube. The bobbin rotates by the
tension of the material, and as we can vary the rotation of the bush
and washer, as before described, we are enabled to vary the drag to suit.
the material. By means of these improvements we can run the spindles.
at a high velocity and spin yarn of fine counts.
And in order that our Invention may be fully understood we will
proceed to describe the accompanying Sheet of Drawings, reference
being had to the figures and letters marked thereon.
Fig. 1 is an elevation of a throstle, spindle, and flyer, with the
improved-arrangement-of-tubes, bobbin, and washer shewn in section.
a is the lifting rail, and 6 the foot step rail; c is the revolving spindle;
g, the wharve fixed upon it, and i the flyer; these parts are made as
usual; e is the outer bush fastened in the lifting rail a, and is the
inner bush which revolves in the bush e, these bushes are similar to
those described in the Specification of Letters Patent granted to us on
the Fourteenth day of September One thousand eight hundred and
sixty-nine, Number 2680. The spindles c fit in the bushes f, thereby
steadying the spindles as they revolve. The under side of the disc f',
on the inner tube frests upon the top of the outer tube e, and tho
bobbin rests upon the flannel or other washer f² placed on the disc f¹.
When the spindle is revolving the friction between the spindle and the
inner bush tends to cause the said bush to revolve and with it the
washer ƒ³, thus forming a rotating drag.
Fig. 2 represents a spindle and flyer suitable for strong doubled yarns
to which a modification of our improved mode of producing the
rotating drag is applied; in this arrangement the bobbin is carried
round with the inner tube ƒ by means of the pin f³ projecting from the
disc f', the circumference of which forms a grooved pulley around
which passes a friction band.
In both the arrangements shewn in Figs. 1 and 2 the speed at which the
bush fis caused to revolve by the rotation of the spindle can be governed
by varying the surface of contact between the under side of the disc f¹
and the upper surface of the outer tube e, and in Fig. 1 the drag can

page_text: be governed by varying the diameter of the washer f³. The improve-
ments above described are applicable to roving frames.
In witness whereof, we, the said Robert Lakin and John Bayley,
have hereto set our hands and scals, this Sixteenth day of August
One thousand eight hundred and seventy.
