Lancaster, Foreman Mechanic, for an Invention of "IMPROVEMENTS
MACHINERY FOR SPINNING FIBRES."
IN
PROVISIONAL SPECIFICATION left by the said Samuel Tweedale at the
Office of the Commissioners of Patents on the 13th May 1881.
SAMUEL TWEEDALE, of Accrington, in the County of Lancaster, Foreman
Mechanic. "IMPROVEMENTS IN MACHINERY FOR SPINNING FIBRES."
This Invention relates to improved construction of spindles, whereby provision is
made to counteract the tendency to lateral motion and vibration by reason of the
bobbin and yarn thereon not being equal or balanced around the axis of the
revolving spindle.
33
In the construction of spindles for purpose aforesaid, according to this my
Invention I construct or employ on the "collar a square shoulder or flange resting
on a shoulder or face formed on the "base" employed for carrying the spindle, the
lower portion of which is by means of a spiral spring connected to a nut at the
bottom of the base piece, or the spring may be applied above the flange or point of
junction of flange of "collar" and "base," and which junction is about opposite the
centre of the driving wharve; the spring and joint, as above described, admit the
requisite play or movement to counteract the tendency to irregular rotation of
bobbin and yarn, and secure even and true rotation thereof.

made to counteract the tendency to lateral motion and vibration by reason of the
bobbin and yarn thereon not being equal or balanced around the axis of the
revolving spindle.

lower portion of the collar is by means of a spiral spring connected to a nut at the
bottom of the base piece, or the spring may be applied above the flange or point of

centre of the driving wharle; the spring and joint, as above described, admit the
requisite play or movement to counteract the tendency to irregular rotation of
bobbin and yarn, and secure even and true rotation thereof.
Such being the nature and object of this my said Invention, in order that the
same may be fully understood, I will now proceed to describe the same in detail,
and in order that the Invention may be fully understood, I have hereunto annexed
a Sheet of Drawings illustrating the same, and have marked the several views with
figures and letters of reference, the same part being marked with like letters of
reference in the several views or Figures.
DESCRIPTION OF THE DRAWINGS.
The several views are vertical sections of spindle & wharle, & its supporting
parts.
Referring now to Fig. 1,—
At A is the spindle; B, its "collar; " the "base" is shown at C, the point of
junction of collar and base is shoulder D; the collar B is slightly tapered, and on its
lower end is a spiral spring E received within the recess F, and secured by nut C;
the spiral spring is compressed, so that its tendancy by expansion against the
shoulder H, and on the nut C to hold and steady the collar B. At H is the usual
bush of bronze or white metal.
It will be seen that the construction of collar and base, as shewn and described,
admit of movement of collar at the shoulder or junction D, whereby the spindle A
adjusts itself to the true vertical position, and the tendancy to centrifugal or
irregular rotation of the spindle is at once counteracted, and perfectly true and
regular rotation of spindle ensues.
Fig. 2 shews a like construction having spiral spring in tension.
Fig. 3 shews a slightly modified application, in which the spiral spring F is
applied on the shoulder of the collar B, the spiral spring F being received within
the recess H, and secured therein by means of the nut C and lock or safety
nut J.
Having thus fully described the nature and particulars of this my said Invention,
together with the manner in which the same is to be or may be performed or
carried into practical effect, I would have it understood that what I claim as my
Invention is,―
The construction and use in combination of the collar B, base C, and spring F,
in manner herein described and substantially as shewn by Drawings annexed.
In witness whereof, I, the said Samuel Tweedale, have hereunto set my hand
and seal, this Eleventh day of November, in the year of our Lord One
thousand eight hundred and eighty one.
Witness,
B. GRIMSHAW,
Accrington.
