MACHINERY FOR PREPARING, SPINNING,
AND DOUBLING."
Sealed the 12th August 1870, and_dated the 18th February 1870.
PROVISIONAL SPECIFICATION left by the said Edward Lord at the
Office of the Commissioners of Patents, with his Petition, on the
18th February 1870.
I, EDWARD LORD, of Todmorden, in the County of York, Machine
Maker, do hereby declare the nature of the said Invention for "IMPROVE.
MENTS IN MACHINERY FOR PREPARING, SPINNING, AND DOUBLING," to be as
follows:-
This Invention is applicable to all the machines used in preparing,
spinning, and doubling cotton and other fibrous materials in which the
slubbing, roving, or yarn passes from the drawing or other rollers to a
bobbin, spool, or spindle.

page_text: My Invention consists in applying between the said rollers and the
bobbin, spool, or spindle a hollow wharve or other equivalent, to which
a rapid rotary motion is given from the drum that drives the bobbins, or
in any other convenient manner. The slubbing, roving, or yarn passes
through this hollow wharve or its equivalent, which is set in such a
position that the twist imparted to the thread, yarn, or roving by the
flyer is carried up to the nip of the rollers. By this means the breaking
of the ends is almost entirely avoided, and the ordinary ring and traveller
or other throstle spinning frames may be made to spin finer counts of
yarn than heretofore.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Edward Lord in the Great Seal Patent Office on
the 17th August 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
LORD, of Todmorden, in the County of York, Machine Maker, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighteenth 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 me, the said Edward Lord, Her special licence, that
I, the said Edward Lord, my executors, administrators, and assigns,
or such others as I, the said Edward Lord, my executors, adminis-
trators, 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, AND DOUBLING," upon the condition (amongst
others) that I, the said Edward Lord, my executors or administrators,
by an instrument in writing under my, or their, or one of 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.

the nature of my 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)
This Invention is applicable to all the machines used in preparing,
spinning, and doubling cotton and other fibrous materials in which the
slubbing, roving, or yarn passes from the drawing or other rollers to a
bobbin, spool, or spindle.
My Invention consists in applying between the said rollers and the
bobbin, spool, or spindle a hollow wharve or other equivalent, to which a
rapid rotary motion is given from the drum that drives the bobbins, or
in any other convenient manner. The slubbing, roving, or yarn passes
through this hollow wharve or its equivalent, which is set in such a
position that the twist imparted to the thread, yarn, or roving by the
flyer or other equivalent is carried up to the nip of the rollers. By this
means the breaking of the ends is almost entirely avoided, and the
ordinary ring and traveller or other throstle spinning frames may be
made to spin finer counts of yarn than heretofore.
And in order that my Invention may be fully understood and readily
carried into operation, I will proceed to describe the accompanying
Drawing, in which Fig. 1 represents a sectional elevation of an ordinary
ring and traveller throstle spinning frame to which my improvements
are applied.
a, a, are the drawing rollers; b and c, the spindle rails supporting the
spindles & and bobbins e; f, f, are the lifting rails containing the rings
and travellers; and is the tin drum for driving the spindles d. These
parts are all made in the ordinary manner.
g
My improvements consist in applying between the drawing rollers a
and the bobbins e the hollow wharve h, shewn full size in Fig. 2. This
hollow wharve is placed in a diagonal position with the lower end above
and in line with the axis of the spindle d, and the upper end is made by
preference bell mouthed. A rapid rotary motion is given to the hollow
wharves by bands from the tin drum g. When the machine is in
operation the twist imparted to the yarn by the traveller is carried
upwards by the rotation of the hollow wharve, and consequently the yarn
between the upper end of the hollow wharve and the front drawing
roller is also twisted to the same or a greater extent than that between
the traveller and the lower end of the hollow wharve; by this means the

page_text: lapping of the front drawing roller and the breaking of the yarn is
almost entirely avoided. In order to increase the friction I prefer to line
the upper end of the hollow wharve with india-rubber or other suitable
substance.
ن
Figs. 3 and 4 represent a modification of my Invention. In this case
the yarn instead of passing through the hollow wharve his acted upon
by the circumference of the rollers j and k, which in revolving carry
the twist forward, as above described, whereas the ordinary fixed guide
retards the twist.
Although I have only described my improvements as applied to a ring
and traveller throstle, I wish it to be understood that they are equally
-applicable-to-other-throstles for-spinning-and-doubling yarn, and to
slubbing and roving frames or other machines of the like description
employed in preparing cotton and other fibres.
When my improvements are applied to throstle spinning frames they
are rendered capable of spinning finer counts of yarn than heretoforc.
Having thus stated the nature of my Invention, and described a
convenient manner of performing the same, I would remark that I do
not limit myself to the shape of the hollow wharve as it may be varied,
and other equivalents may be employed to carry the twist upwards to the
nip of the drawing rollers, and I claim the use of a revolving hollow
wharf or other equivalent placed between the bobbin, spool, or spindle
and the drawing or other rollers in the manner and for the purpose
described.
In witness whereof, I, the said Edward Lord, have hereto set my
hand and seal, this Sixteenth day of August One thousand eight
