page_text: LETTERS PATENT to David Skeoch of the firm of Charles Skeoch and Son
of Stewarton in the County of Ayr, North Britain for an Invention of
"IMPROVEMENTS IN THE SPINDLES AND FLYERS OF SPINNING FRAMES"
PROVISIONAL SPECIFICATION left by the said David Skeoch at the Office
of the Commissioners of Patents on the 8th May 1883.
DAVID SKEOCH of the firm of Charles Skeoch and Son of Stewarton in the
County of Ayr, North Britain "IMPROVEMENTS IN THE SPINDLES AND FLYERS
OF SPINNING FRAMES"
This Invention which relates to Improvements in the Spindles and flyers of
Spinning Frames has for its object to ensure that the flyers shall at all times
remain true or concentric with the axis, of the spindles on or with which they
rotate.
Great difficulty has been experienced in the past in ensuring the continuance of
the spindle in this condition owing to the formation or shape of the seat on the
spindle against which the boss of the flyer rests, and the present improvements
consist in forming the spindle with a continuous conical surface extending from
the root or base of the screw downwards over and out to the full diameter of the
collar so that no ledge or projection or flat seat is left. The lower part of the boss
below the screw in the flyer is made of a similar conical form so that when screwed
down over the screw at the top of the spindle it closes down and rests upon the
corresponding conical seat whereby the tendency of the spindle in rotating is
always to tighten the flyer upon the conical seat so that its concentric position is
continuously maintained. :

DAVID SKEOCH of the firm of Charles Skeoch and Son of Stewarton in the
County of Ayr, North Britain IMPROVEMENTS IN THE SPINDLES AND FLYERS
OF SPINNING FRAMES
"
"
My said Invention which relates to Improvements in the Spindles and flyers of
spinning frames has for its object to ensure that the flyers shall at all times remain
true or concentric with the axes of the Spindles on or with which they rotate.
Great difficulty has been experienced in the past in ensuring the continuance of
the spindle and the flyers in this condition owing to the formation or shape of the
seat on the spindle against which the boss of the flyer rests and the present
improvements consist in forming the spindle with a continuous conical surface
extending from the root or base of the screw downwards out to the full diameter
of the spindle so that no ledge or projection or flat seat is left and also so that as
the conical hole in the flyer wears it has a conical surface of larger diameter on the
spindle to bear or rest upon the lower part of the boss below the screw in the flyer
being made of a corresponding conical form so that when screwed down over the
screw at the top of the spindle, the said boss rests upon the conical surface in the
manner as set forth above whereby the tendency of the spindle in rotating is
always to tighten the flyer upon the increasing conical surface of the spindle so
that the concentric position of the flyer is continuously maintained as distinct from
such conical bearing surfaces as have been hitherto used, when the conical seat or
*hole in the flyer has not had an enlarged conical portion of the spindle to rest
upon.
And in order that my said invention may be properly understood I now proceed
more particularly to set forth the system, inode or manner in or under which the
same is or may be used or practically carried into effect, reference being had to the
accompanying Drawing and to the letters and Figures marked thereon that is
to say:
Figure 1, is a front elevation of the upper part of a spindle fitted with flyer
both constructed according to and constituting my present Invention.
Figure 2 is a side elevation of the same.
Figure 3, is a front elevation (shewn partly in section) of the same.
In carrying my present Invention into practice I construct the spindle a, with
the continuous conical surface b, extending from the root or base end of the screw c,
to the full diameter of the spindle a.-The lower part of the boss or collar, which
is made of a corresponding conical form is screwed down over the screw c, at the
top of the spindle a, and rests upon a portion of the extended conical surface b, as-
shewn in Figure 3, whereby the tendency of the spindle a, in rotating is always to
tighten the Hyer d, upon the said conical surface b, so that the concentric position
of the flyer is continuously maintained, the conical portion e, of the flyer d, losing
no bearing surface by wear by virtue of a part of the enlarged conical surface as
at b, being continuously presented to the bearing surface e of the flyer as the
bearing surface of the flyer increases in diameter by wear.
"
Having now described and particularly ascertained the nature of my said
Invention and the system mode or manner in or under which the same is or may
be used or practically carried into effect I would observe in conclusion that
what I consider to be novel and original and therefore claim as the Invention
secured to me by the hereinbefore in part recited Letters Patent is:-
In the construction of Spindles and flyers of spinning frames, constructing the

page_text: spindle a, with the bearing surface b, thereon, extending to a larger diameter than
that of the conical bole in the flyer d, so that as the said hole in the flyer d, wears
it always has a complete bearing surface provided for it corresponding to the wear
as herein before described and shewn on the annexed Sheet of Drawings.
In Witness Whereof I the said David Skeoch have hereunto set my hand and
seal this fourteenth day of November in the year of our Lord One thousand eight
hundred and eighty three
