Improvements in Spindles and Flyers or Tops for Spinning, Twisting
and Winding Machines.
I, JOHN MACFLE, of North Park, Rutherglen, in the County of Lanark, North
Britain, Engineer, do hereby declare the nature of this invention to be as
follows, that is to say:
My said invention has for its object to improve the construction of spindles,
and Hyers or tops for spinning, twisting, and winding machines. My improve-
ments are such that the flyer or top can be made out of a single piece of metal
without requiring it to be forged, bored, and screwed as is necessary to be done
with flyers or tops as hitherto constructed. My improvements also considerably
facilitate the applying of the flyer or top to its spindle and the doffing of the
same.
In carrying out my invention form a portion of the upper end of a spindle
with flat sides and I also form a groove or notch in the upper end of the spindle
and in each edge near the lower part of the flat sides.
In forming the flyer I take a piece of steel or other suitable wire and bend
it, by preference, in a heated state by use of a mandril and die or block or other
suitable means, so that it will be made to assume a shape having a twisted head
like a staple. The staple part when the flyer is applied to the spindle, as herein-
after described, will lie in the groove in the top of the spindle and extend down
the flat sides. At the bottom of the staple part a semicircular twist is given to
each part of the wire and parts of these semicircular twists engage one in each
groove in the edges of the flat sides of the spindle. The wires extend from the
twists more or less horizontally across the flat sides of the spindle and are bent
down to form the legs which are formed with an eye in the usual manner.
In applying or doffing the flyer the worker simply presses the legs slightly
inwards and this opens the semicircular twists sufficiently to allow the twisted
head to be slipped on to or off the upper end of the spindle. When in use the
centrifugal force tends to make the twists grip firmly in the lower grooves as
herein before described, thus insuring that the flyer remains in position, the staple
part extending down the flat sides of the spindles also insuring that the flyer
revolves with the spindle.
In some cases the lower grooves in the spindle may be dispensed with the
centrifugal force being sufficient to cause the semicircular twists to grip the
spindle firmly enough to retain the flyer in position when in use.
In cop winding machines the top" is formed substantially as herein before
described for a flyer, parts of the wire extending out horizontally from the semi-
circular twists being substituted for the enlarged part of the top as usually con-
structed for guiding the thread. The upper end of the spindle is also formed as
herein before described to suit the improved form of top.

Improvements in Spindles and Flyers or Tops for Spinning, Twisting,
and Winding Machines.
I, JOHN MACFIE, of North Park, Rutherglen, in the County of Lanark, North
Britain, Engineer, 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, that is to say:
My said invention has for its object to improve the construction of spindles,
and Hyers or tops for spinning, twisting, and winding machines. My improve-
ments are such that the flyer or top can be made out of a single piece of metal
without requiring it to be forged, bored, and screwed as is necessary to be done
with flyers or tops as hitherto constructed. My improvements also considerably
facilitate the applying of the flyer or top to its spindle and the doffing of the
same.
And in order that my said invention and the manner of performing the same
may be properly understood I hereunto append a sheet of explanatory drawings
to be hereinafter referred to in describing my improvements.
Figures, 1, 2, and 3, of the drawings, are respectively a plan, a front elevation,
and a side elevation of one modification of the improvements. Figures, 4, and 5,
are views similar to Figures, 1, and 2, but with a part removed. Figures, 6,
7, and 8, are views similar to Figures, 1, 2, and 3, of a second modification of the
improvements. Figures, 9, and 10, are a plan and a front elevation of a third
modification. In these drawings the same reference letters are used to mark the
same or like parts wherever they are repeated.
In carrying out the invention according to the first modification shown in
Figures, 1, to 5, a portion of the upper end, A, of the spindle, B, which receives
the flyer, C, is formed with flat sides, D, and a groove or notch, E, shown in
Figures, 4, and 5, is formed in the top edge of the flattened part, a similar
notch, I, being likewise formed in each lateral edge near the lower part of the
flat sides, D. The improved flyer, C, is made of steel or other suitable wire,
and is formed with a twisted head, H, resembling a staple, the wire being bent
to the desired form, preferably when heated, by means of a mandril and die or
block, or other suitable apparatus. When the flyer, C, is applied to the spindle, B,
as hereinafter described, the staple head, H, its over the flattened end of the
spindle, so that its top part engages in the groove or notch, E, in the end of the
spindle. At the bottom of the staple head, H, the parts, J, extending down the
fat sides, D, are bent like parts of a two-threaded screw into a semicircular twist
and so as to fit round the edges of the Hat sides, and engage in the grooves or
notches, F, formed therein. The portions of the wire after being bended round
the edges are made to extend more or less horizontally across the flat sides out-
wards in opposite directions and are then bent downwards to form the legs of
the flyer in the usual way. In applying or doffing the flyer, C, the two legs are
pressed slightly towards each other thereby causing the parts bent round the
edges of the flat sides to open sufficiently to allow the staple head, H, to be
slipped on to or off the upper end of the spindle. When the fiyer, C, is rotating,
the centrifugal force causes the twisted parts to grip the spindle head firmly.
In some cases the lower grooves or notches, F, may be dipsensed with, the centri-
fugal action being found sufficient to cause the twisted parts fitting round the 4
edges of the flat sides, 1), to grip the spindle firmly enough to retain the flyer
in position when rotating. Also in some cases the upper part of the spindle
need not be flattened provided the top notch, E, is made sufficiently deep for the
staple head, H, to sit securely in it and thus ensure that the flyer is carried round
by the spindle.

page_text: The modification shown in Figures, 6, 7, and 8, is adapted for winding yarn
in the form of cops for shuttles. The cop is wound in an inverted position on
a spindle, B, the winding proceeding within a conical cup, Q, fixed to the framing
from which cup the spindle and cop rise as the winding proceeds. The yarn, R, is
led from a traversing guide (not shown) through a slot, S, formed in the side of
the cup, Q, and when the winding of a cop is being started is applied round a
"top" screwed on to the upper end of the spindle, B. This "top" as hitherto con-
structed is formed with a notch in its edge in which the yarn is caught at starting
and held so as to become wound on the spindle, B. When the cop is completed
the "top" is unscrewed and the cop removed, the loose upper end of the yarn
being used to thread the shuttle. The "top" according to my invention where
it is attached to the spindle is formed substantially in the same way as the flyer
head herein before described. The staple parts, J, however, are thinned or Hat-
tened to some extent, so as to give greater resiliency to the wire, and thereby
enable the "top" to be applied or doffed with comparative ease. The top 18
formed with horizontal hooked arms, K, L, formed by extending out each part
of the wire from the spindle after it has been twisted round the edges of the flat
sides, D, and passed across the flat sides, the arms so formed being substituted
for the notched part of the top as usually constructed for catching the yarn. The
upper end, A, or the spindle, B, for receiving the improved "top" is formed as
in the modification herein before described.
In another modification of a top shown in Figures, 9, and 10 the top is
formed with horizontal arms K, L, as in the previous modification, but instead
of the arms terminating in hooked parts, they are extended and bent round to
form opposite semicircular or bow shaped parts, M, N, the ends of which are
bent under and held by the horizontal arms, a part, P, of each arm being left
clear to act as a catch for the thread. The top" so constructed, by reason of
the. bow shaped parts, is somewhat more easily applied and doffed than the top
described in the previous modification.
"
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
1. Improvements in spindles and flyers for spinning and twisting machines,
comprising a flyer formed with a twisted staple-like head, fitting on to the upper
end of a spindle notched on the top, substantially as and for the purposes herein-
before described with reference to Figures 1 to 5 of the accompanying drawings.
2. In spindles and tops for winding machines, constructing part of the top,
where it is attached to the spindle, and the upper end of the spindle substantially
in the same way as the flyer head, and the upper end of the spindle referred to
in the previous claim, the top being formed with projecting horizontal arms,
with or without semicircular parts, substantially as and for the purposes herein-
before described with reference to Figures 6 to 10 of the accompanying drawings.
3. In spinning twisting and winding machines, constructing the upper end
of a spindle for flyers and the like, with flat sides, the top end of the spindle
being formed with a notch, and the edges of the flat sides being formed with or
without notches, substantially as and for the purposes herein before described with
reference to the accompanying drawings.
4. A flyer or top for spinning twisting or winding machines formed with a twisted
staple-like head, substantially as and for the purposes herein before described
with reference to the accompanying drawings.
