Improvements in Spindles and Flyers for Spinning and Twisting
Frames.
I, HUGH DUNBAR MOMASTER, of Gilford, Ireland, Manufacturer, (a communication
to me from abroad by David Frazer, Iron Fitter, of 310, Tompkins Avenue, Brooklyn,
N.Y., U.S.A.,) do hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in spindles and flyers for spinning and
twisting frames, and has for object the doing away with the trouble of removing
the flyers when doffing or changing the bobbins, and at same time the obtaining
a much greater speed than with the ordinary flyer. And in order that my invention
on the accompanying
may be more readily understood, I have shewn the same
sheet of drawings.
A. is the flyer neck made hollow, or bored through its entire length, to allow
the bobbin spindle to traverse through it.
The neck rail is a double rail fitted with bushings and caps, in which the flyer
spindle revolves.
At B. the bobbin is traversed at the top of the inverted flyer.
At C. the bobbin is traversed at the bottom of the inverted flyer.
:
D. shows the bobbin spindle running right through the flyer spindle, with the
flyer leg at the top showing the end turned with an eye to receive the yarn.
In this form the spinner, who attends the frame, has no effort to make in putting
the yarn in the eye of the flyer, for as soon as the yarn strikes the leg, it runs
into the eye.
E. shows the top of the neck rail with the caps screwed on, tightening the
bushings.
By this the flyer spindle can always be kept steady, and can be driven to any
speed, consistent with the quickest possible speed of the boss roller.
F. shows the empty bobbin with the groove in the bottom.
G. shows the washer with tongue into which the bobbin groove sits, and by
which the bobbin is turned.
H. shows the roller running on the eccentric, with adjustable screws in the step
rail, or builder.
I. is the casting in which the roller runs, having a spud on each end, fitted in
a hollow snug or slot. This keeps it always steady on the eccentric.
J. is a brake or drag on the hottom spindle wharve, which drag can be fitted
with a spiral spring at the back of the step rail, or builder.
This step rail is to run the length between the bearers of the frame, and to be
fitted with slides inside the bearers.
With these inverted flyers, there is nothing to do in doffing the yarn, but cut
the thread, and lift off the bobbin. This can be done much more expeditiously
than spinning frames can now be doffed.
Dated this Sth day of November 1859.

Improvements in Spindles and Flyers for Spinning and Twisting
Frames.
I, HUGH DUNBAR MCMASTER, of Gilford, Ireland, Manufacturer, (a communication
to me from abroad by David Frazer, Iron Fitter, of 310, Tompkins Avenue, Brooklyn,
N.Y. U.S.A.) do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement:-
My invention relates to improvements in spindles and flyers for spinning and
twisting frames, and has for its object the doing away with the trouble of removing
the flyers when doffing or changing the bobbins and at same time obtuming
a much greater speed than with the ordinary flyer. And in order that my said
invention may be more readily understood, I have shewn the same on the sheet
of drawings filed with the Provisional Specification.
A. is the flyer neck made hollow, or bored through its entire length, to allow.
the bobbin spindle to traverse through it.
The neck rail is a double rail fitted with bushings and caps, in which the flyer
spindle revolves,
At B. the bobbin is traversed at the top of the inverted flyer.
At C. the bobbin is traversed through at the bottom of the inverted flyer.
D. shows the bobbin spindle running right through the flyer spindle, with the
flyer leg at the top showing the end turned with an eye to receive the yarn. In
this form the spinner, who attends the frame, has no effort to make in putting the
yarn in the eye of the flyer, for as soon as the yarn strikes the leg, it runs into
the eye.
E. shows the top of the neck rail with the caps screwed on, tightening the
bushings. By this the flyer spindle can always be kept steady, and can be driven
to any speed, consistent with the quickest possible speed of the boss roller.
F. shows the empty bobbin with the groove in the bottom.
G. shows the washer with tongue into which the bobbin groove sits, and by
which the bobbin is turned.
H. shows the roller running on the eccentric with adjustable screws in the step
rail or builder.
I. is the casting in which the roller runs; having a spud on each end fitted in
a hollow snug or slot.
This keeps it always steady on the eccentric.
J. is a brake or drag on the bottom spindle wharve, which drag can be fitted
with a spiral spring at the back of the step rail or builder. This step rail is to
run the length between the bearers of the frame and to be fitted with slides
inside the bearers.

With these inverted flyers, there is nothing to do in doffing the yarn, but cut
the thread, and lift off the hobbin.
This can be done much more expeditiously than by the method by which
spinning frames are now doffed.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
The improvements in spindles and flyers for spinning and twisting frames,
substantially as herein before described and shown and for the purpose set forth.
