AN IMPROVE- MENT IN THROSTLE SPINDLES FOR SPINNING AND TWISTING SILK, COTTON, WOOL, FLAX, AND OTHER FIBROUS SUBSTANCES
Year: 1831

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
LAMBERT, of Regent Street, in the Parish of Saint James, Westminster, in the
County of Middlesex, Gold Laceman, send greeting.
WHEREAS His most Excellent Majesty King William the Fourth, by His
Royal Letters Patent under the Great Seal of Great Britain, bearing date
at Westminster, the Second day of June, in the first year of His reign,
after reciting therein that I, the said Samuel Lambert, had, by my Petition,
humbly represented unto His said Majesty that I, by a communication
from a certain Foreigner residing out of His Majesty's Dominions, had
become possessed of the knowledge of an Invention, being "AN IMPROVE-
MENT IN THROSTLE SPINDLES FOR SPINNING AND TWISTING SILK, COTTON, WOOL,
FLAX, AND OTHER FIBROUS SUBSTANCES," did give and grant unto me, the
said Samuel Lambert, my exors, admors, and assigns, His especial licence,
full power, sole privilege, and authority, that I, the said Samuel Lambert,
my exors, adiiors, and assigns, and every of them, by myself and themselves,
or by my and their deputy or deputies, servants or agents, or such others as
I, the said Samuel Lambert, my exors, adññors, or assigns, should at any time
agree with, and others, from time to time and at all times thereafter during
the term of years therein expressed, should and lawfully might make, use,
exercise, and vend the said Invention within that part of His United King-
dom of Great Britain and Ireland, called England, His Dominion of Wales,
and Town of Berwick-upon-Tweed, in such manner as to me, the said Samuel
Lambert, my executors, admors, and assigns, or any of them, should in ny or
their discretion seem meet, and that I, the said Samuel Lambert, my exors.

page_text: admors, and assigns, should and lawfully might have and enjoy the whole
profit, benefit, commodity, and advantage from time to time coming, growing,
accruing, and arising by reason of the said Invention, for and during the term
of years therein mentioned; in which said Letters Patent there is contained
a proviso that if I, the said Samuel Lambert, should not particularly describe
and ascertain the nature of the said Invention, and in what manner the same
is to be performed, by an instrument in writing under my hand and seal, and
cause the same to be inrolled in His Majesty's High Court of Chancery within
four calendar months next and immediately after the date of the said Letters
Patent, that then the said Letters Patent, and all liberties and advantages
whatsoever thereby granted, should utterly cease, determine, and become void,
as in and by the said Letters Patent, relation being thereunto had, will more
fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Samuel Lambert, do hereby declare that the said Invention consists in certain
Improvements in Throstle Spindles for Spinning and Twisting Silk, Cotton,
Wool, Flax, and other Fibrous Substances. And in further compliance with the
said proviso, I, the said Samuel Lambert, do hereby declare that the manner
in which the said Invention is to be performed and carried into effect is set
forth and ascertained by the Drawing hereto annexed, and the description
thereof herein-after contained.
The Drawings are of the full size of the common throstle spindle and bobbin.
Figure 1 exhibits the spindle and its appendages in section. Figure 2 gives
a geometrical representation of the same. Figures 3, 4, 5, and 6 display
some of the picces separately, in which any peculiarity of construction in any
way appertaining to the said Invention exists. In the several Figures, reference
is made to the same parts in all by the same letters. A represents a cylin-
drical spindle of steel or other fit metal, having a hole drilled longitudinally
and centrally in the direction of its axis, from the upper extremity of the
spindle to the depth of about three inches. This perforation is referred to in
the sectional Drawing by the letter d. The spindle, being of due dimensions
for the kind of thread which it is designed to spin, is to be fixed by its lower
extremity, so as not to admit of rotation to the spindle rail or other part of the
framing of the machine. The perforation in the spindle is intended to receive
a pin E of steel or other metal fitting into it, so as to allow the pin to rotate
freely, but without shake, in the hole, and being in length not sufficient to
rest upon the bottom. The pin E has near its upper extremity a screw
thread (left-handed as it is termed commonly), upon which the nut of the flyer
F is screwed, till it comes in contact with tho shoulder c of the pin. Betwixt

page_text: the shoulder c of the pin and the top of the spindle A a collar or washer of
leather c is interposed. The spindle being fixed, the bobbin B is made to,
turn upon it; and this motion it receives by resting upon the warve, whirl, or
pulley C, also turning on the spindle, and the warve is driven by a baud
passing round it and round the spindle drum. The warve C has a tube of
metal f, about two inches and a half long, attached to it, and passing through
it centrally, over which the bobbin drops and rests upon the upper concave
surface of the warve, into which is fixed a catch pin a, to take a similar
catch pin in a hollow, in the bottom of the bobbin. Below the warve
C, upon the spindle, is placed a simple loose pulley or warve D, upon
which the driving band may be slipped when it is necessary to stop the
motion of the bobbin. The warve D, with or without the intervention of
a washer, rests upon the bobbin board or rail G of the rising frame, the
thread receiving its twist by the rotation of the bobbin round which it is
being wound, and passing through one of the eyes of the flyer, describes in
its course by this angular deflection the side and base of a cone, and carrys
round with it the flyer and its central pin. In this improved construction of
the spindle for spinning machinery, there is no more strain upon the thread
betwixt the delivery rollers and the bobbin than that which is necessary to
overcome the friction of the flyer pin in its socket in the spindle; and that
resistance being as nearly as possible uniform, the thread is not liable to be
broken by occasional inequalities of pull, and therefore, the interruptions being
less frequent, and the consequent waste being diminished, the amount of work
done by the machine will be in that proportion augmented.
Having now described the improved means of equalising the strain upon
the thread as it passes from the delivery rollers, by detaching the flyer from
the spindle, I do hereby declare that the said Invention consists in the method
or means to be employed for that purpose herein-before described; and I de-
clare that I claim as the Invention referred to in the said Letters Patent
such detached flyer, moveable by the action of the thread in the process of
spinning, and the perforated spindle in which the flyer pin turns. And I
further declare that I do not claim as parts of the said Invention such other
parts of spinning machinery as are in common use, herein adverted to in de-
scribing the action of this improved spindle.
In witness whereof, I, the said Samuel Lambert, have hereunto set my
hand and seal, this Twenty-first day of September, in the year of our
Lord One thousand eight hundred and thirty-one.
SAMUEL (Ls.) LAMBERT.

page_text: AND BE IT REMEMBERED, that on the Twenty-first day of September,
in the year of our Lord 1831, the aforesaid Samuel Lambert came before our
said Lord the King in His Chancery, and acknowledged the Specification,
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.
