Year: 1879

page_text: LETTERS PATENT to William Sutcliffe, Mill Manager, and James Greenwood,
Spindle and Flyer Maker, both of Halifax, in the County of York, for the
Invention of "IMPROVEMENTS IN MACHINERY FOR SPINNING AND DOUBLING
FIBRES"
PROVISIONAL SPECIFICATION left by the said William Sutcliffe and James
Greenwood at the Office of the Commissioners of Patents on the 11th August
1879.
WILLIAM SUTCLIFFE, Mill Manager, and JAMES GREENWOOD, Spindle and Flyer
Naker, both of Halifax, in the County of York. “IMPROVEMENTS IN MACHINERY
FOR SPINNING AND DOUBLING FIBRES."
This Invention relates to the flyers used for spinning and doubling fibres, and
the object of this our said Invention is to so construct flyers as to prevent the "end"
or fibre under operation fouling or catching on or rubbing against the flange of
the bobbin.
Flyers made according to this our said Invention have in addition to the curl at
the extremities of the legs a curl or twist forined at the shoulders or bends of the
flyer, so that when the end or fibre is passed first through the shoulder curl, thence
through the bottom or ordinary curl it is thus guided down the leg of the flyer,
and kept entirely clear of the flanges of the bobbin.
The construction above described being much cheaper than hollow legs or wing
plates.

Office on the 10th February 1880.
WILLIAM SUTCLIFFE, Mill Manager, and JAMES GREENWOOD, Spindle and Flyer
Maker, both of Halifax, in the County of York. "IMPROVEMENTS IN MACHINERY
FOR SPINNING AND DOUBLING FIBRES."
This Invention relates to the flyers used for spinning and doubling fibres, and
the object of this our said Invention is to so construct flyers as to prevent the
" end
or fibre under operation fouling or catching on or rubbing against the
flange of the bobbin.
"
Flyers made according to this our said Invention have in addition to the curl
at the extremities of the legs a curl or twist formed at the shoulders or bends of
the flyer, so that when the "end" or fibre is passed first through the shoulder curl,
thence through the bottom or ordinary curl, it is thus guided down the leg of the
flyer and kept entirely clear of the flanges of the bobbin.
The construction above described being much cheaper than hollow legs or wing
plates.
Such being the nature and object of this our said Invention, we have hereunto
annexed Drawings showing the construction of our improved flyer. Figs. 1 and 2
being elevations; Fig. 3, a plan view.
It will be seen the flyer has an additional curl or twist B at each of its shoulders
or bends, so that the "end"
or fibre C being passed through either of the curls B,
thence through the bottom or ordinary curl E to the bobbin F is thus guided down
the leg of the flyer, and prevented catching the top flange of the bobbin.
Having thus fully described the nature and particulars of this our said Invention,
we claim the manufacture and use of "Flyers" having the additional curl or
twist B, B, as illustrated and described, and for purposes herein set forth.
In witness whereof, I, the said William Sutcliffe, for and on behalf of myself
and the said James Greenwood, have hereunto set my hand and seal,
this Ninth day of February, in the year of our Lord One thousand eight
hundred and eighty.
Witness,
