CERTAIN IMPROVEMENTS. IN MACHINERY OR APPARATUS EMPLOYED IN SPINNING COTTON AND OTHER FIBROUS SUBSTANCES
Year: 1862

page_text: LETTERS PATENT to Henry Ashworth, of Littleborough, in the County of
Lancaster, Manufacturer, for the Invention of "CERTAIN IMPROVEMENTS.
IN MACHINERY OR APPARATUS EMPLOYED IN SPINNING COTTON AND OTHER
FIBROUS SUBSTANCES."
Sealed the 15th July 1862, and dated the 5th February 1862.
PROVISIONAL SPECIFICATION left by the said Henry Ashworth at the
Office of the Commissioners of Patents, with his Petition, on the 5th
February 1862..
I, HENRY ASHWORTH, of Littleborough, in the County of Lancaster, Manu-
facturer, do hereby declare the nature of the said Invention for "CERTAIN
IMPROVEMENTS IN MACHINERY OR APPARATUS EMPLOYED IN SPINNING COTTON AND
OTHER FIBROUS SUBSTANCES," to be as follows:-
My Invention relates to that description of machinery employed in spinning
known as "throstles" and doubling frames, and the first part thereof is
designed to impart a more even and regular "drag" to the bobbins.
The Invention consists, first, in the employment of an endless band of felt
or other material passing beneath the bobbins, having "washers" interposed,
such endless band being distended between two vertical rollers, but depressed
into a horizontal position (as beneath the bobbins) by other horizontal rollers.

page_text: When the band is at a proper and required tension, the revolution of the
bobbins causes or imparts to the band by frictional contact a slow but regular
travelling motion, constituting a perfect "drag" upon the washer and bobbins,
and with less wear to such "drag band" than hitherto, by reason of its
continual movement.
The Invention consists, secondly, in the formation and use of a projection
upon the arm of the "flyer," arranged and shaped in such a manner as to catch
up the slack yarn which sometimes occurs between the flyer and guide wires,
and prevent it coming into contact with the revolving bobbin.

SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Henry Ashworth in the Great Seal Patent Office on the
18th July 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
ASHWORTH, of Littleborough, in the County of Lancaster, Manufacturer; send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifth day of February, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-fifth 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 the said Henry
-Ashworth, my 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 "CERTAIN IMPROVEMENTS IN
MACHINERY. OR APPARATUS EMPLOYED IN SPINNING COTTON AND OTHER FIBROUS
SUBSTANCES," upon the condition, amongst others, that I, the said Henry
Ashworth, by an instrument in writing under my hand and seal, should par-
ticularly 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.
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,
'

page_text: to be particularly described and ascertained in and by the following statement
and accompanying Drawings (that is to say):-
My Invention relates to that description of machinery employed in spinning
known as "throstles" and doubling frames, and the first part thereof is
designed to impart a more even and regular "drag" to the bobbins.
The Invention consists, first, in the employment of an endless band of felt
or other material passing beneath the bobbins, having "washers" interposed,
such endless band being distended between two vertical rollers, but depressed
into a horizontal position (as beneath the bobbins) by other horizontal rollers.
When the band is at a proper and required tension, the revolution of the
bobbins causes or imparts to the band by frictional contact a slow but regular
travelling motion, constituting a perfect "drag' upon the washers and
bobbins, and with less wear to such "drag band" than hitherto, by reason of
its continual movement.
"
The Invention consists, secondly, in the formation and use of a projection
upon the arm of the "flyer," arranged and shaped in such a manner as to
catch up the slack yarn which sometimes occurs between the flyer guide wires,
and prevent it coming into contact with the revolving bobbin.
In order that the Invention may be better understood and explained in
detail, I have hereunto attached a Sheet of Drawings made about the actual
size, similar letters of reference being marked upon corresponding parts of
the apparatus.
Fig. 1 is a side view representing a portion of the bobbin rail and bobbins,
having the improved drag band shewn beneath them; Fig. 2 is an end view
of the same; Fig. 3, a plan view; and Fig. 4 exhibits a modification in the
form of the end of the rail.
In Fig. 1, a, a, is the bobbin rail, and 6 the endless "drag band," distended
between the bowls or rollers c, c, and depressed into a horizontal position by
the rollers d, d, so as to offer a flat surface to the washers e, e, of the
bobbins ff. The friction and revolution of the washers and bobbins causes
the endless band to travel continuously around the bowls c, c, and thus the
great wearing of the band is prevented. In Fig. 4 the end of the rail a is
turned at right angles, the bowl being placed horizontally to economize space.
The second part of the Invention consists in the formation of the pro-
jections g on the flyers, which is so arranged as to catch the slack yarn which
sometimes occurs between the flyer and the guide wires, thereby preventing it
coming into contact with the bobbin.
Having now described the nature of the said Invention, together with the

page_text: to-be
method of carrying the same into practical effect, I wish it to be distinctly
understood that I claim,-
First, the novel employment and use of an endless band beneath the
bobbins, to act as a "drag" upon the bobbins, and so arranged as to receive
a continual travelling movement from the revolution of the bobbins.
And, secondly, I claim the application and use of the projections gas
applied to flyers for the purpose of catching up loose or slack yarn, as herein-
before described, set forth, and fully illustrated in the Drawings attached.
In witness whereof, I, the said Henry Ashworth, have hereunto set
my hand and seal, this Sixteenth day of July, in the year of our
Lord One thousand eight hundred and sixty-two.
HENRY ASHWORTH. (L.S.)
