Sons, of the Grecian Mills, Bolton, in the County of Lancaster, Cotton Spinners
and Doublers, and Robert Ramsden, of the same Place, Manager, for the
Invention of "IMPROVEMENTS IN MACHINERY FOR SPINNING AND DOUBLING
COTTON, SILK, WORSTED, WOOLLEN, LINEN, AND OTHER FIBROUS MATERIALS."
Scaled the 26th May 1876, and dated the 31st March 1876.
PROVISIONAL SPECIFICATION left by the said John Leigh Taylor and Robert
Ramsden at the Office of the Commissioners of Patents on the 31st March
1876.
JOHN LEIGH TAYLOR, of the Firm of Thomas Taylor and Sons, of the Grecian
Mills, Bolton, in the County of Lancaster, Cotton Spinners and Doublers, and
ROBERT RAMSDEN, of the saine Place, Manager. "IMPROVEMENTS IN MACHINERY
FOR SPINNING AND DOUBLING COTTON, SILK, WORSTED, WOOLLEN, LINEN, AND
OTHER FIBROUS MATERIALS."
Our Invention relates to the machines known as throstle spinning and doubling
frames, and it consists in an improved mode of connecting inverted flyers to the
spindles and in supporting the bobbins. The flyer is provided with a stud in the
under side of the bottom flange, which stud fits in notches or holes in a plate fixed
to the top of the spindle; by this means the bobbin is carried round at a uniform
speed. The inverted flyer is connected to a bush made of metal, wood, or other
suitable material, the lower end of which bears upon a flannel or other washer
placed on the lifting rail; this washer gives the requisite drag to the flyer.
The advantages obtained by by our improvements are,
No oil is required for the spindle to lubricate the bobbin after dofling as
heretofore.
No snarling of the yarn on the top of the spindle can take place.
No friction of thread against flyer leg.
And, no removing of flyers when doffing.
A great saving of waste is effected and of time in doffing, and the bobbins can be
doffed whilst the frame is going.
As the bobbins bear upon metal plates they are not liable to be saturated with
oil, and consequently no oil can penetrate to the yarn on the bobbin as heretofore.

the said John Leigh Taylor and Robert Ramsden in the Great Seal Patent
Office on the 28th September 1876.
JOHN LEIGH TAYLOR, of the Firm of Thomas Taylor and Sons, of the Grecian
Mills, Bolton, in the County of Lancaster, Cotton Spinners and Doublers, and
ROBERT RAMSDEN, of the same Place, Manager. "IMPROVEMENTS IN MACHINERY
FOR SPINNING AND DOUBLING COTTON, SILK, WORSTED, WOOLLEN, LINEN, AND OTHER
FIBROUS MATERIALS."
Our Invention relates to the machines known as throstle spinning and doubling
frames, and it consists in imparting a positive motion to the bobbin on which the
yarn or thread is wound, and a variable motion to the inverted flyer, which is fixed
to a bush bearing upon a flannel or other washer placed on the lifting rail.
And in order that our Invention may be fully understood we will proceed to
describe the accompanying Sheet of Drawings.
Fig. 1 is an elevation in section of an ordinary throstle doubling frame, to which
our improvements are applied; Fig. 2 is a front view of one end of the same.
Fig. 3 is a full sized view of our improved spindle and flyer; and Fig. 4
represents a flyer constructed so as to give increased friction to the yarn in throstle
spinning. In Figs. 1 and 2, a is the crecl; b, the troughs; c, the press rollers; d,
the driving drum; e, the lifting rails; f, the foot step rails; and g, the shafts for
the lifting pulleys; all these parts are made in the usual manner; h is the spindle,
see Fig. 3, which is supported below in a foot step, and above in a bolster in tho
rails and e, as usual; and i is the ordinary bobbin which bears upon the plate h¹
connected to the spindle by a key or otherwise, so that it can be easily removed
when required; in this plate is a stud fitting into a hole in the under side of the
bottom flange of the bobbin; by this or other equivalent means the bobbin is
carried round by the spindle, which is driven as usual from the drum d, as shewn in
Fig. 1. The inverted flyer j is fixed to the bush k, which is made of metal, wood,
or other suitable material, and the lower surface of this bush bears upon a flannel
or other washer resting on the lifting rail e, the drag produced by the weight of the
flyer and the bush on the washer causes the flyer to wind the yarn or thread on to
the bobbin at the requisite tension; and this tension can be regulated as required
by the strength or firmness of the yarn or thread by increasing or reducing the
weight of the bush, or by varying the size of the washer or the material of which it
is made.
In order to reduce the friction of the bush on the spindle it may be desirable to
apply small brass tubes at the upper and lower ends of the bush, as shewn in the
Drawing, or to increase the diameter of the hole in the middle part of the bush,
leaving a portion at each end to fit on the spindle.
When the machine is at work the rising and falling of the lifting rail e causes
the flyer to wind the yarn evenly over the whole length of the bobbins, the
bobbins remaining at the same level.
In applying our improvements to throstle spinning frames it is evident that the
troughs and pressing rollers c are dispensed with, and in lieu thereof the ordinary
drawing rollers are employed.
The advantages obtained by our improvements are,-
First. No oil is required for the spindle to lubricate the bobbin after doffing as
heretofore.
Secondly. No snarling of the yarn on the top of the spindle can take place in
consequence of the flyer being removed from the top of the spindle.
Thirdly. No friction of thread against the flyer leg in doubling, but in throstle
spinning an additional eye may be made in the flyer leg, as shewn in Fig. 4,
through which the yarn is taken, and then carried one or more times around the
flyer leg before it is wound on the bobbin, or the increased friction if required may
be obtained in any other convenient manner.
Fourthly. No removing of flyers when doffing.

page_text: Fifthly. A considerable saving of power owing to the greater steadiness of the
spindle.
Sixthly. A great saving of waste is effected and of time in dolling, and the
bobbins can be doffed whilst the frame is going.
And, lastly. As the bobbins bear upon metal plates they are not liable to be
saturated with oil, and consequently no oil can penetrate to the yarn on the bobbin
as heretofore, and as the bobbins are carried round with the spindles no internal
friction takes place, thereby rendering them more durable.
Having thus stated the nature and particulars of our Invention, we declare that
what we claim as our improvements in machinery for spinning and doubling cotton,
silk, worsted, woollen, linen, and other fibrous materials is the combination of a
bobbin which is carried round by the spindle with an inverted flyer, which is
carried round by the yarn or thread, the requisite drag being obtained by the
friction of a flannel or other washer placed between the bush k and the lifting rail e,
as shewn and described.
In witness whereof, we, the said John Leigh Taylor and Robert Ramsden,
have hereto set our hands and seals, this Twenty-seventh day of September,
One thousand eight hundred and seventy-six.
