page_text: I, ROBERT SCAIFE of Colne in the County of Lancaster Spindle Maker seek
leave to amend the Specification of Letters Patent No 2707 of 1882 as shewn
in red ink in the Copy of the original Specification hereunto annexed that is
to say.
By striking out the word "First "in line 4 page 4:
By striking out all between the 9th and 15th lines of page 4 both inclusive.
By inserting after line 15 of page 4 the words "I desire it to be understood that
I do not claim as my Invention the use of the bobbin tube e, of the felt or cloth
washers g¹ h³ and of the flyer i nor the use of two rails only but that what I do
claim is the use of the long collar in combination with a "dead" or stationary
spindle substantially as set forth and described.
My reasons for making this amendment are that the Specification does not
distinguish that which is new and of my invention from that which is old and that
the "advantages" set forth arise only in part from the use of the long collar in
combination with the dead spindle.
In the matter of the application made by Robert Scaife for leave to amend the
Specification of Letters Patent N° 2707 of 1882.
I hereby grant leave to the said Robert Scaife to amend the said Specification

LETTERS PATENT to Robert Scaife, of Colne in the County of Lancaster,
Spindle Maker for an invention of IMPROVEMENTS IN MACHINERY OR

My improvements relate to throstle-spinning or doubling, with a dead or stationary
spindle, and consist in the use of a long collar fitting upon the said spindle, and in
a guard for preventing broken threads from interfering with the other threads.
In carrying out my invention I use only two rails, the ordinary foot-rail and
the moving "collar" or "bolster" rail. The ordinary foot-step is dispensed with,
the lower end of the dead or stationary spindle being fixed in the foot-rail where
the foot-step is usually placed. The upper end of the said stationary spindle
extends to near the guide wire board, and the said spindle is held perfectly steady
by means of a long collar or bolster fixed in the "collar" or "bolster" rail. Upon
the said long collar a tube revolves, the lower portion of the said tube being
grooved to carry a driving band or tape. "The said tube carries the bobbin and a
Hange or collar on this tube carries a felt or cloth washer, a similar washer being
fixed to the bottom of the bobbin, thus ensuring the positive motion of the said
bobbin by friction, without danger of slipping. The upper end of the said dead or
stationary spindle is bored to receive the flyer spindle. As the flyer revolves the
contact of its legs with the air and the friction of the flyer spindle in the hole of
the dead spindle give the necessary tension to the yarn. The flyer is prevented
from over-running the bobbin, by means of a small felt or cloth washer fixed to
the upper end of the flyer spindle, the said washer being always, in contact with
the flyer.

My improvements further consist in a," guard" fixed to the guide-wire board, or
at some convenient place between each Hyer, all along the frame on both sides.
The said guard prevents the broken threads from interfering with those which are
spinning perfectly.
The advantages derived from these improvements are as follows
First. The spindle being stationary and fixed in the bottom rail, and the collar
being also stationary and fixed in the top rail, the tube (on which the bobbin is
placed) running on the collar, can be run at a much higher speed than the ordinary
throstle spindle, and yet retain its steadiness, consequently a greater length of yarn
can be spun in any given time, thereby lessening the cost of spinning.
Second-The tube on which the bobbin rests, being the only part required to be
driven (the bearings of which are reduced to a minimum) and the cloth drag,
required in ordinary throstle spinuing, being entirely dispensed with, a very great
saving in power is effected.
Third. The drag or tension of the yarn required in spinning being obtained by
the resistance of the atmosphere against the flyer, a perfectly uniform drag is
acquired, thereby lessening the breakages of yarn when spinning.

washer being always in contact with the top of the dead spindle and thus acting
as a brake upon the flyer.
