CERTAIN IMPROVEMENTS IN MACHINERY OR Appa- RATUS FOR SPINNING AND TWISTING COTTON AND OTHER FIBROUS SUBSTANCES
Year: 1850

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
SAUL, of Manchester, in the County of Lancaster, Cotton Spinner; send
greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by
Her Letters Patent under the Great Seal of Great Britain, bearing date
at Westminster, the Fifth day of September, in the fourteenth year of
Her reign, and in the year of our Lord One thousand eight hundred
and fifty, did, for Herself, Her heirs and successors, give and grant unto
me, the said John Saul, Her especial license, full power, sole privilege and
authority, that I, the said John Saul, my exors, adñiors, and assigns, and
such others as I, the said John Saul, my exors, adññors, or assigns, should at
any time agree with, and no others, from time to time and at all times during
the term of years therein expressed, should and lawfully might make, use,
exercise, and vend, within England and Wales, and the Town of Berwick
upon-Tweed, my Invention of "CERTAIN IMPROVEMENTS IN MACHINERY OR Appa-
RATUS FOR SPINNING AND TWISTING COTTON AND OTHER FIBROUS SUBSTANCES;" in
which said Letters Patent is contained a proviso, that I, the said John Saul,
shall cause a particular description of the nature of my said Invention, and in
what manner the same is to be performed, to be enrolled in Her Majesty's
High Court of Chancery within six calendar months next and immediately
after the date of the said in part recited Letters Patent, as in and by the same,
reference being thereunto had, will more fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
John Saul, do hereby declare that the nature of the said Invention, and the
manner in which the same is to be performed, is particularly described and
ascertained in and by the Drawings hereto annexed, and the following expla-
nation thereof, that is to say:
My improvements in machinery or apparatus for spinning and twisting
cotton and other fibrous substances apply solely to the well-known spinning
and doubling frame called the throstle, and especially to that particular
construction or arrangement of the spindle and flyer in the "throstle" which
formed the subject-matter of Letters Patent granted to Henry Gore, of
Manchester, and bearing date at Westminster, the Twenty-second day of
September, One thousand eight hundred and thirty-one, the Specification of
which was duly enrolled in the Enrollment Office (since expired), and commonly
called "Gore's tube spindle." My improvement consists in the application,
employment, or use of a loose tube, betwixt the present (or Gore's) fixed or
steadying tube and the bobbin, whereby the lower bush of the said bobbin
is prevented from coming into contact with the aforesaid fixed or steadying
tube, and the intense friction which has hitherto taken place between the
lower bush of the bobbin and the fixed tube is transferred to the said loose
tube, and is there capable of being regulated at pleasure by means of cloth,
leather, or other washers, placed above and beneath a flanch or collar, (formed
at the lower end of the said loose tube), about the same diameter as the
bottom of the bobbin intended to be used thereon, and turned either flat,
Founded, or dished, as may be desirable for the work to be performed; the
amount of friction to which the bobbins are subjected being by this means
considerably reduced, their durability is consequently very greatly increased,
and much higher "numbers" or finer qualities of yarn may be either spun or
doubled by this means than has hitherto been practicable on this description
of spinning or .doubling frame. The bobbins may be constructed either with
or without metal .bushes: In spinning fine "numbers," where a high velocity
is required, it is desirable to attach a fly wheel to each "throstle" frame, in order
to prevent the same from being stopped or started too rapidly, and thus
obviate the liability of the bobbins to overrun themselves.
In order more clearly to show the practical application of my improvements,
I have attached to these Presents a Sheet of Drawings, representing my
improvements in machinery or apparatus for spinning and twisting cotton and
other fibrous substances, drawn full size, and have marked the same with
figures and letters of reference corresponding with those in the following
description thereof.

page_text: Figure 1 is a front elevation of the spindle, flyer, and bobbins, &c.,
conplete; and Figure 2 is an elevation of the spindle and flyer, shewing
the copping rail, the fast and loose tubes, and the bobbin, in section. a, a, is
the copping rail; b, b, is the spindle; c, c, the flyer; and d, d, the bobbin ;
e, e, is the ordinary fixed (or "Gore's ") tube, which is made fast to the copping
rail a, a, in the usual manner; f. f, is the loose tube (constituting my im-
provement), which is placed betwixt the tube e and the bobbin and has a
flanche or collar g, g, formed at its lower end; this tube is shewn detached at
Figure 3. h, h, are washers, of cloth, leather, or other suitable material,
placed above and below the flanche or collar g. 9, by which means the amount
of friction or "drag" upon the bobbin may be regulated at pleasure.
Having thus described the nature and object of my said improvements,
together with the method of carrying the same into practical effect, I would
remark, in conclusion, that I claim as my Invention, the application, employ-
ment, or use of a loose tube betwixt the ordinary fixed (or "Gore's ") tube and
the bobbins in the aforesaid description of machines, in the manner and for
the purpose above particularly set forth, and as represented at f. f. 9, 9, in tho
Drawings annexod.
In witness whereof, I, the said John Saul, have hereunto set my hand
and seal, this Fourth day of March, in the year of our Lord One
thousand eight hundred and fifty-one..
AND BE IT REMEMBERED, that on the Fourth day of March, in the
year of our Lord 1851, the aforesaid John Saul came before our said Lady the
Queen in Her Chancery, and acknowledged the Specification aforesaid, and all
and every thing therein contained and specified, in form above written. And
also the Specification aforesaid was stamped according to the tenor of the
Statute made for that purpose.
Enrolled the Fifth day of March, in the year of our Lord One thousand
