WHEREAS I am in possession of an Invention for " IMPROVEMENTS
IN MECHANISM FOR SPINNING WOOL," and have petitioned Her Majesty to
O grant unto me, my_executors, administrators, and assigns, Her Royal
Letters Patent for the same, and have made solemn Declaration that

page_text: seal, fully describes and ascertains the nature of the said Invention,
and in what manner the same is to be performed, in and by the
following statement, reference being had to the accompanying Drawing
forming a part of this Specification :—
The said Invention consists,-
First. In the application to a frame (with suitable draw rollers
adapted for wool) of rings and travellers in combination with the
spindles.
1
And, second. In an improvement in the means for applying the
said rings and travellers used in cotton spinning to the spinning of 1
wool.
The advantages in point of rapidity and economy of production from
the employment of ring spinning frames in the place of flyer frames
in spinning cotton have long been understood. Attempts have been
frequently heretofore made to apply the same system in the spinning 2
of worsted and woollen yarns, but without any practical success until
the improvement herein-after described.

page_text: Figures 7 and 8 shew how the bobbins are wound in the two systems
of spinning.
Figures 9 and 10 are views respectively of flat and round wire
travellers.
The two systems of spinning are shewn in comparison in the Drawing
for the purpose of illustrating the subject. In cotton manufacture a
flattened traveller is used like that shown at Figure 9, and this form is
necessary to be employed. The structure of wool is however so
different from that of cotton that it is impossible to spin it with a
traveller of this form on account of the small fibres which radiate from
the main thread catching upon and winding themselves around the
traveller, causing constant breakage of the yarn. Instead therefore of
constructing the traveller after the form necessary in spinning cotton
its ends a, Figure 10, where it embraces the flanges of the ring A,
Figure 5, are flattened in order that the traveller may be as free as
possible from a rocking movement and may run steadily upon
the ring,
but the body portion 6 which comes into contact with the yarn is
rounded so as to give free passage to the yarn. By this change in the
construction of the traveller the system of ring spinning can be applied
with perfect success to the manufacture of woollen yarns. It is
not absolutely necessary that the horns or ends a of the traveller
should be flattened, though the quality of the yarn is much improved
thereby. Any worsted fly frame of ordinary construction as shewn at
Figure 2 can be changed to a ring spinning frame by a slight alteration
in the arrangement of the lifting rail and the substitution of rings
suitably mounted in a rail and furnished with travellers of the character
described. A frame so adapted is shewn at Figure 1. The manner
in which the spinning operation is performed requires no description,
as the same is apparent from the Drawing and will be readily under-
stood by any person acquainted with the art of spinning.
Having thus fully described the said Invention as communicated
to me by my foreign correspondents, I wish it understood I am
aware that a ring and traveller in combination with a spindle and
bobbin have been employed for many years in machines for spinning
cotton yarns, but I am not aware that a ring and traveller have ever
before been combined with a frame constructed and adapted for spinning
wool; I therefore claim,―

page_text: First. The application to a machine (furnished with draw rollers
adapted for wool) of rings and travellers in combination with the
spindles and bobbins, substantially as herein set forth.
Second. The employment in combination with a ring A in a spinning
frame of a traveller constructed substantially as herein set forth.
In witness whereof, I, the said William Robert Lake, have hereunto
set my hand and seal, this Twenty-eighth day of January, in the
year of our Lord One thousand eight hundred and seventy.
WILLIAM ROBERT LAKE. (L.S.)
Witness,

Clerk to Messrs. Haseltine, Lake, & Co.,
