Year: 1877

page_text: LETTERS PATENT to John Albert Bright, of Rochdale, in the County of
Lancaster, Cotton Spinner and Manufacturer, for the Invention of "IMPROVE
MENTS IN MACHINERY FOR SPINNING AND DOUBLING." A communication from
abroad by Joseph M. Pusey, Lea Pusey, and Edward Pusey, all of Wilmington,
Delaware, America.
Sealed the 8th February 1878, and dated the 15th September 1877.
PROVISIONAL SPECIFICATION left by the said John Albert Bright at the
Office of the Commissioners of Patents on the 15th September 1877.
JOHN ALBERT BRIGHT, of Rochdale, in the County of Lancaster, Cotton Spinner
and Manufacturer. "IMPROVEMENTS IN MACHINERY FOR SPINNING AND DOUBLING."
A communication from abroad by Joseph M. Pusey, Lea Pusey, and Edward Pusey,
all of Wilmington, Delaware, America.
This Invention relates principally to certain improvements in what are known as
the ring and traveller throstle spinning and doubling frames, and it consists in an
improved mode of constructing the machines, whereby the spindles may be driven
at a high speed without vibrating.
The machine consists of a frame supporting the spindles, which instead of being
perfectly rigid, as is the case in the ordinary dead spindles, are capable of moving
slightly in a lateral direction; each spindle is acted upon at two points by a spring,
the lower end of which fits in a groove to prevent the spindle rising; the springs
are fixed to adjustable supports.
The bobbins fit on tubes, which are driven by bands from the ordinary driving
drum, passing around a wharve on each tube. By this means the spindles have a
slight play in their supports, and the tendency to vibrate is overcome by the spring,
as any movement of the upper end of the spindle would be communicated to the
lower end and cause the spring to yield, thus preventing the return motion
necessary to vibration.

page_text: A division plate is placed between the bobbins to prevent the yarns from the
adjacent bobbins coming in collision, and a break lever acted upon by the knee of
the operator is applied to the lower end of each tube to check the momentum of
the bobbin when piecing up, or for other purpose.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said John Albert Bright in the Great Seal Patent Office on the 13th March
1878.
JOHN ALBERT BRIGHT, of Rochdale, in the County of Lancaster, Cotton Spinner
and Manufacturer. "IMPROVEMENTS IN MACHINERY FOR SPINNING AND DOUBLING."
A communication from abroad by Joseph M. Pusey, Lea Pusey, and Edward Pusey,
all of Wilmington, Delaware, America.
This Invention relates to certain improvements in what are known as the ring
and traveller throstle spinning and doubling frames, and it consists in an improved
mode of constructing the machines, whereby the bobbins or spools on which the
yarn is wound may be driven at a high speed without causing the spindle to
vibrate.
The machine consists of a rail or frame supporting the spindles, which instead of
being perfectly rigid, as is the case in the ordinary dead spindles, are capable of
moving slightly in a lateral direction in the bearings; each spindle is acted upon
by a spring, one end of which fits in a groove to prevent the spindle rising.
The bobbins or spools fit on tubes, which are driven by bands from the ordinary
driving drum, passing around a wharve on each tube.
And in order that this Invention may be fully understood and readily carried
into operation, I will proceed to describe the accompanying Drawing, which
represents a sectional elevation of the improved machinery.
cup e.
a is a dead spindle supported in the frame b; the tube c fits on the upper part
of the spindle a, and the bobbin or spool on which the yarn is wound fits on the
tube c, near the lower end of which is cast or fixed the wharve d, which is turned
round by a band from the ordinary driving drum. The end of the tube c enters the oil
To the rail b is fixed the spring f; this spring presses against the spindle at
the groove a¹; the object of this groove is to prevent the spindle rising.
The holes in the frame 6 must be slightly larger than the spindle a, so that the
spindle may have a little play in its bearings, but the spring f must be sufficiently
strong to keep the spindle still when the tube c is revolving. By this means the
tendency of the spindles to vibrate is overcome by the spring f, as any movement
of the upper end of the spindle would be communicated to the lower end and
cause the spring to yield, thus preventing the return motion necessary to produce
vibration.
The Invention may be modified by making both ends of the spring f to act on
the spindle a, and the shape of the spring and the mode of applying it may be
varied.
Having thus stated the nature of the Invention communicated to me, nd
described a convenient manner of performing the same, I declare that I claim,

page_text: supporting the "dead" or fixed spindles of machines used in spinning and doubling
yarn, in such wise that they may yield when required, and so prevent the vibration
which has hitherto been unavoidable when driving the bobbins or spools at high
velocities on tubes running on such "dead or fixed spindles.

In witness whereof, I, the said John Albert Bright, have hereunto set my
hand and seal, this Twelfth day of March, One thousand eight hundred
and seventy-eight.
