TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
ASHWORTH, of Walsden, in the County of Lancaster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Nineteenth day of January, 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 Henry Ashworth, Her special license,
that I, the said Henry Ashworth, my executors, administrators, and
assigns, or such others as I, the said Henry Ashworth, my executors,
administrators, and assigns, should at any time agree with, and no
others, from time to time and 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
APPARATUS FOR SPINNING AND DOUBLING COTTON AND OTHER FIBROUS SUBSTANCES,"
upon the condition (amongst others) that I, the said Henry Ashworth,
my executors or administrators, by an instrument in writing under my,
or their, or one of their hands and seals, should particularly describe

page_text: 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.
NOW KNOW YE, that I, the said Henry Ashworth, do hereby declare
the nature of the said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by
the following statement, and accompanying Drawings (that is to
say):-
"
This Invention is applicable to spinning machines called "throstles
and also to doubling frames used for doubling yarns or threads, and
consists principally in dispensing with the ordinary drag cloth or washer
cloth, and in imparting the necessary drag to the bobbins by means of
vanes or wings acting against the air.
I employ the ordinary throstle and doubling spindle with a fixed
wharve and with the flyer screwed on at the top in the usual manner,
and in place of the ordinary bushes or collars in the lifting rail I fix
vertical tubes standing about four inches above the top of the rail, so as
to have a long bearing for the spindle, by which means I am enabled to
run the spindles much faster and steadier than usual. Upon this fixed
tube I place loosely a second tube which carries the bobbin quite free of
the spindle, being provided with a flange for supporting the same and
a driving pin or peg fitting into a hole in the bottom of the bobbin.
This loose tube is also provided with projecting wings or vanes, which
by acting against the atmosphere as they revolve give the required
amount of drag to the bobbin.
By using wings or vanes of a larger or smaller area any desired
amount of drag may by given, according to the different fineness of
the yarn to be spun or doubled.
Such being the nature and object of my said Invention for "Improve-
ments in Apparatus for Spinning and Doubling Cotton and other Fibrous
Substances," I will now proceed to describe more in detail the manner
in which the same is to be or may be carried into practical effect, and in
order that the same may be clearly understood, I have annexed hereunto
a Sheet of Drawings illustrative thereof, and have marked the same with
figs. and letters of reference corresponding with those in the following
explanation thereof (that is to say): -
Fig. 1 in the annexed Drawing represents an elevation of a throstle

page_text: spindle with my improvements applied thereto, and Fig. 2 is a vertical
section shewing more clearly the fixed and loose tubes; Fig. 3 is an
elevation (full size) of the loose tube which carries the bobbin, and
Fig. 4 a plan view of the same. a, a, is the spindle rail; b, b, the lifting
rail, and c, c, the bobbin; d, d, is the spindle. In the lifting rail b, b, is
fixed a series of vertical tubes e, e, driven in tight, and upon each of
these is mounted loosely a second tube f, f, which carries the bobbin c, c,
and drives it by the pin g, g.
This loose tube is fitted with a vane h, h,
which by acting against the air as above described gives the required
amount of drag to the bobbin.
As a modification of the above in some cases I propose to dispense
with the vanes and insert a cloth or other washer i, i, between the lower
flanges of the two tubes, as shown in section at Fig. 5.
Having now described the nature and object of my said Invention of
"Improvements in Apparatus for Spinning and Doubling Cotton and
other Fibrous Substances," together with the manner in which the same is
to be or may be performed or carried into practical effect, I wish it to be
understood that I claim as my Invention, the combination of the vertical
tube fixed in the lifting rail with the loose tube revolving thereon and
carrying the bobbin quite clear of the spindle, whether the latter tube
be provided with wings or vanes h, h, as shown at Figs. 1, 2, 3, and 4,
or with a cloth or other suitable washer i, i, as shown at Fig. 5, or any
mere modification or imitation thereof constructed and operating in
substantially the same or a similar manner.
In witness whereof, 1, the said Henry Ashworth, have hereunto
set my hand and seal, this Eighteenth day of July, in the year
of our Lord One thousand eight hundred and seventy.
