Year: 1882

page_text: LETTERS PATENT to Abraham Milne Fletcher, of Oldham, in the County of
Lancaster, Mill Manager, for an Invention of "IMPROVEMENTS IN OR
APPLICABLE TO THROSTLE, SPINNING, AND DOUBLING FRAMES."
PROVISIONAL SPECIFICATION left by the said Abraham Milne Fletcher
at the Office of the Commissioners of Patents on the 4th February 1882.

My Invention relates to a modification or modifications of the collar bearing for
the spindle and bobbin of the ordinary Hyer throstle and doubling frames, so that
increased speed may be obtained with greater steadiness and the "dragi can be
regulated in the ordinary manner, and for each change of counts. My Invention
consists in making an addition to the ordinary collar bearing for the spindle to
extend upwards through the drag plate on which the lower end of the bobbin rests,
and up some distance into the barrel of the bobbin which is formed with a bush to
fit the spindle at the top, and another bush lower down within the barrel, or one
long bush from the top is used for fine counts, these two bushes or the long bush
acting to keep the bobbin central with the spindle, and preventing the lower part
of the interior of the barrel from rubbing or working against the said projection.
from the collar bearing.
There is one or more holes drilled through the projection from the collar for
the spindle, to allow the oil or lubricant filled into the cup of the collar to pass from
it to the spindle.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Abraham Milue Fletcher in the Great Seal Patent Office on the
28th July 1882.

the spindle and bobbin of the ordinary flyer throstle and doubling frames, so that

My Invention consists in making an addition to the ordinary collar bearing for
the spindle to extend upwards through the drag plate on which the lower end of
the bobbin rests, and up some distance into the barrel of the bobbin which is
formed with a bush to fit the spindle at the top, and another bush lower down
within the barrel, or one long bush from the top is used for fine counts, these two
bushes or the long bush acting to keep the bobbin central with the spindle, and
preventing the lower part of the interior of the barrel from rubbing or working
against the said projection from the collar bearing.
There is one or more holes drilled through the projection from the collar for the
spindle to allow the oil or lubricant filled into the cup of the collar to pass from it
to the spindle.
Fig 1 is a elevation in section of a spindle and its connected parts for flyer
throstle spinning and doubling, and Fig 2 is a sectional elevation of the bobbin
detached according to iny Invention.
a is the spindle; b the flyer; c the footstep rail; c¹ its cover; & the collar and
copping rail; cover or collar rail; and e the drag cloth. All these parts are of
the ordinary arrangement and construction.
My Invention consists in forming the collar d² with a long upward projection d³
to pass into without touching the interior of the barrel of the bobbin f, which is
constructed with the lower bush f' partly up the interior of the barrel or with a
long bush from the top of the bobbin. is the upper bush of the barrel of the
bobbin.
There are one or more holes for the oil to pass from the cup part of the
collar d² to the spindle, and there is a slight cup at the top of the tube d³ to receive
the oil put upon the blade part of the spindle when the bobbin is doffed; d³ is a
pin to fix the position of the collar in the rail d.
I have now particularly described the nature of my said Invention and the mode
of carrying the same into effect and claim as my Invention.
Firstly. In ordinary flyer throstlo spinning and doubling frames where the
drag is regulated in the ordinary manner, the combination of a tube bearing in
the copping and spindle rail, arranged to pass up into the interior of the barrel of
the bobbin without touching it, as hereinbefore described and illustrated by the
Drawings:
Secondly. The combination of the bobbin constructed as herein before described,
with a tube bearing, spindle and copping rail, of ordinary flyer throstle spinning
and doubling frames, as hereinbefore described and illustrated by the Drawings.

In witness whereof I the said Abraham Milne Fletcher have hereunto set my
hand and seal this
in the year of our Lord Ono
thousand eight hundred and eighty two.
