IN FLYERS FOR SPINNING AND WINDING MACHINERY."
"IMPROVEMENTS
This Invention relates to certain improvements in the spindles and flyers of
spinning and winding machinery, and is particularly designed to reduce the friction
of the thread in its guides or guiding eyes when being wound on to the bobbins,
thereby preventing undue wear of such guiding parts and frequent breakage of
the thread or yarn.
By one improvement of the Invention small guide rollers of metal, delf, or other
material are substituted for the usual guiding wires soldered or fixed to the extreme
ends of the limbs of the flyers. These rollers are fitted free to revolve on small
studs or pins, screwed, rivetted, or otherwise fixed to the flyer limbs in such a
position that the thread passing from the thread plate is guided over or round
them to the bobbin.
By the rotation of the rollers while the thread passes over their surfaces the
friction of the thread on the guides, which with the old forms of fixed wire guides
was sufficient to cut through the wires, is reduced to a minimum. When the guide
rollers or their studs become worn they can be readily replaced, and the improved
guide rollers can be fitted to the flyers of spinning frames at present in use at very
little cost.
By a further improvement the flyer spindle is continued up above the flyer
limbs to the thread plate, and terminates in a conical top fitting into a corre-
sponding conical opening in the thread plate or bearing. This upward continuation
of the flyer spindle and forming of a bearing or guide for it in the thread plate,
prevents the undue vibration of the flyer or spindle, which occurs when it is
revolving at a high speed. The yarn or thread instead of passing through the
thread plate passes through an opening in the conical top of the flyer spindle, and
the friction and wear of the thread striking against the sides of the opening in the
thread plate are thus obviated or reduced. The "boss roller" above is also placed
vertically over the flyer spindle instead of being as usual to one side.

"IMPROVEMENTS
My said Invention relates to certain improvements in the spindles and flyers of
spinning or twisting and winding machinery, and is particularly designed to reduce
the friction of the thread in its guides or guiding eyes when being wound on to
the bobbins, thereby preventing undue wear of such guiding parts, and frequent
. breakage of the thread or yarn.
And in order that my said Invention and the manner of performing the same
may be properly understood, I have hereunto appended for that purpose a Sheet of
explanatory Drawings to be hereinafter referred to, and representing modifications
of my improvements in flyers. The same letters are used to indicate the same or
like parts in the various Figures.
Figure 1 of these Drawings is a front elevation of part of a throstle spinning
frame, showing my improved flyers as applied thereto; and Figure 2 is a transverse
section of the same; Figures 3 and 4 are front and side elevations of one modification
of my improved flyers shown detached; Figures 5 and 6 are a side elevation and
plan, showing the novel conical top of the flyer; and Figures 7 and 8 are front and
side elevations of an ordinary flyer with my improved guide roller applied
thereto.
Referring to these Drawings, the improved flyers F, FL, are fixed on the upper
ends of the flyer spindles S, which are carried as usual to revolve in the footstep
bearing bushes in the step rail B, and in guiding bushes in the neck rail B¹, and
are driven by ordinary list bands on the whorls W. The general arrangement of
⚫ the throstle frame is not materially different from that of ordinary spinning frames,
the features of novelty or improvements being confined to the flyers and to the
arrangement of the rollers leading the yarn or roving thereto.
By one improvement of my said Invention small guide rollers f of metal, delf,
or other material, are substituted for the guiding wires usually soldered or fixed to
the extreme ends of the limbs F of the flyers. These rollers fare fitted free to
revolve on small studs or pins f¹, which may be screwed, rivetted, or otherwise
fixed to or even fitted loosely in the flyer limbs F, in such a position that the
thread t passing from the thread plate P is guided over or round them to the
bobbin T. These rollers may either be fitted in countersunk recesses in the flyer
limb F, as shown in Figures 3 and 4, or they may be fitted on separate shanks f
with a covering shield f³, such shanks being either tubular, as shown, to form a
-socket for the flyer limb, or be made in the form of a wire, which may be inserted
in a hole drilled in the flyer limb, and in either case being readily fitted to ordinary
flyers in use. By the rotation of the rollers f while the thread passes over them
the friction of the thread on these as guides (which with the old forms of fixed
wire guides was sufficient to cut through the wires) is reduced to a minimum.
When the guide rollers for their studs f¹ become worn they can be readily
replaced, and particularly in the form shown applied in Figures 7 and 8, the
improved guide rollers f can be fitted to the ordinary.flyers of spinning frames at
present in use at very little cost.
By a further improvement the flyer spindle F" or revolving centre of the flyer is
continued up above the flyer limbs F to the thread plate P, as shown in Figures 1
and 2, and terminates in a conical top F2 fitting into a corresponding conical
opening in the thread plate or bearing P. This upward continuation of the flyer

page_text: spindle F, and forming of a bearing or guide F for it in the thread plate P, prevents
undue vibration of the flyer F or spindle F', which occurs when it is revolving at a
high speed. The yarn or thread & instead of passing through the thread plate P
passes through an opening formed in the conical top F of the flyer spindle F'
(a slit Fs being made for convenience of entering the yarn t), and the friction and
wear of the thread, which in the ordinary arrangement strikes against the sides of
the opening in the thread plate, are thus obviated or reduced.
The boss rollers R above, which guide the yarn t to the flyer, are by my Invention
placed vertically over the flyer spindle F', instead of being as usual to one side, it
being unnecessary when the conical top F is fitted to the flyer to have the thread
coming down at an angle, as is usual for the purpose of preventing the thread flying
out of the thread plate. When ordinary flyers, such as are shown in Figures 7
and 8 fitted with the improved roller guides f are used, the boss rollers R would
still require to be fitted further back in the throstle frame to give a slope or angle
to the yarn to retain it in the thread plate.
Having thus particularly described my said Invention, and the manner of
performing the same, I have to state that I do not restrict myself to the precise
details herein described or delineated, but what I believe to be novel and original,
and therefore claim as the Invention secured to me by the hereinbefore in part
recited Letters Patent, is,-
First. The construction of flyers for spinning or twisting and winding machinery
with roller guides f, substantially as and for the purposes herein set forth and
delineated.
Second. The construction of flyers for spinning or twisting and winding
machinery with the spindles or revolving centres F1 extended upwards, and
terminating in a conical top F³ guided in the thread plate or rail, substantially as
and for the purposes herein set forth and delineated.
Third. In combination with flyers of spinning or twisting and winding machinery
having conical tops the arrangement of the boss rollers or nipping rolls R to
guide the rove or yarn vertically over the centre of the flyer, substantially as
herein set forth and shown in the accompanying Drawings.
Fourth. The combination in flyers for spinning or twisting and winding
machinery of an extended spindle with conical guiding top F1, F2, and of guiding
rollers f, substantially as and for the purposes herein set forth, and as shown'in
the accompanying Drawings.
In witness whereof, I, the said David Frazer, have hereunto set my hand
and seal, this Fifth day of September, in the year of our Lord One thousand
night hand and and niche
