Improvements in the Construction of Flyers for Twisting, Doubling,
and Spinning Frames, and Twine Laying Machines.
I, FRIEDRICH RAICHL, of Palanka, Hungary, 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 :-
My invention has for its object an improved construction of flyers.by means of
which twice and in some cases three times greater length of sliver or yarn can be
treated than with flyers such as hitherto constructed.
The essential feature of my invention is to impart a twist in two points of the
yarn instead of in one only as hitherto practised.
In the first case I need only have half the number of twists at each point and
am thus able to operate on double the length of yarn the two twists being given
one at the entrance or feed end of the sliver into the flyer as heretofore and the
other inside the flyer near the other end of the same.
In the second case one twist is given at the feed end and the other two inside.
the flyer near the other end of same after passing through the second guide which
is fixed to the bridge on the left hand end.
According to the first form of my invention I fix inside a flyer of ordinary
construction such as used in horizontal rope spinners, etc. and close to each end
thereof a diametrical bar or bridge provided with a central perforation serving as
a bearing for the journals of the bobbin carrier or spindle which remains
motionless. The said journals carry a rectangular inner half flyer consisting of
two vertical side bars or, pieces suspended to the said journals and secured to a
horizontal rod on which moves the ordinary winding regulator or slide.
•
In horizontal flyers this inner half fiyer hangs loosely but in vertical flyers it, is
held in position by any suitable meaus. The bridge carries a pin actuating a set
of gear wheels whereby motion is imparted to the bobbin.
The bridge at the other end is also provided with a pin whereby motion is
imparted to two hawl pulleys and to the slide.
The sliver or yarn after having passed through a suitable guide and through
the hollow axis passes over the pair of hawl pulleys keyed between the front end
of the flyer and the adjoining bridge upon corresponding toothed wheels driven
by the pulley mounted on the said hollow axis.
Another driving pulley arranged at the other end of the flyer imparts a rotary
motion to the flyer. The sliver passes from one end of the flyer to the other
along one of the arms of the same and passes over small guide pulleys through
another guide of similar construction to the above and through a passage or duct
formed in the carrier journal and having such a shape as to allow the yarn to.
enter at one end of the journal and pass through the side of the same inside the.
flyer where it is led over a couple of hawl pulleys driven in a similar manner to
the hawl pulleys at the other end and leading it.to the winding regulator or slide
whence it is wound up upon the bobbin.
This winding regulator or slide is of ordinary construction and well known and
needs no further description here.
It is in this passage or duct that the second twist is imparted to the sliver or
yarn by the rotating flyer.
A suitable holder loosely mounted on an axis let into the inner end of the carrier
journal holds the bobbin carrier at the point where it can be detached to fit on or
remove the bobbin.

page_text: This holder H consists of a rectangular slab hinged in any suitable manne
at a and having a projection h a spring u³ formed to hold the top portion of the
holder H in position when said top portion is shut upon the lower half of this
holder and a cylindrical hole a formed in same to act as a bearing for the
carrier c. The projection h is so formed that it can be driven tightly into the
journal j.
According to the second form of my invention I construct an entire flyer
mounted on the carrier journals or on inner bosses formed in the central part of
the bridges and keyed at one end to the carrier journal but loose at. the other so
that it rotates in the same direction as the carrier but in a reverse direction to that
of the outside flyer.
One driving pulley actuates the outer flyer at one end and another similar
pulley drives the inner flyer which imparts by suitable gear wheels an independent
motion to the bobbin whilst the outside flyer imparts with the aid of the bridge a
rotary motion to the hawl pulleys and to the slide. A guide is fixed to the left
hand side bridge and another guide is placed as usual in front of the flyer at the
feed end of the same.
Three twists are thus given to the sliver or twine one after the yarn has passed
through the outer guide and the other two after it has passed through the inside
guide.
This arrangement is applicable to horizontal as well to, vertical flyers.
In the accompanying drawings where like letters of reference indicate
corresponding parts
Fig. 1 is a sectional view of the first construction of flyer imparting two twists
to the sliver or yarn Fig. 2 is a section on line za of Fig. 1.
Figs. 3, 4, 5, 5 and 6, are detail views of the carrier holder, of the bridges of
the ends of the inner flyer and of the arms driving the gear, wheels respectively.
Fig. 7 is a half sectional view of the flyer constructed according to the second
part of my invention Fig. 8 is a section on the line of Fig. 7 while Fig. 8ª is
a section on line of Fig. 7.
With reference to Figs. I to 6, F is the outside or ordinary flyer f is the inner
halt flyer suspended to the journals; j¹ of the carrier c; one of these journals is
fixed to the bridge b' on the left band side whilst the other end turns loosely in a
boss of the bridge b. The carrier c is fulcrummed at the left hand end to the
journal and is held by the holder H at the other end, this holder being fixed by
its projection h into the inner end of the journal ; (Fig. 1).
This inner half flyer consists of two sides (Fig. 5^) ff' secured together by a.
longitudinal rod f1 (Fig. 1) on which moves the slide g³.
The bridge carries a pin which actuates the arm a (Figs. 5 and 6) in the
same manner as a carrier of a lathe. The said arm a is fixed to the spur wheel w
which drives the wheel w¹ which also (being on the same axis) drives the friction:
pulley Z which gears with the other friction pulley Z which pulley has a pin q on
its periphery which pin drives B. by means of the side m². The bridge b' likewise
carries a pin which drives the arm a' in the same manner as above described.
The arm a¹ is.fixed to the spur wheel w of the gearing to which wheel actuates
the said gear w³, whereby motion is imparted to the hawl pulleys pl and to the
winding regulator or slide 9°.
.
The carrier ends at t and can be detached in order to receive the bobbin B and
is held down at that point by the spring holder H aforesaid (Fig. 3).
The sliver or yarn y shewn in dot and dash lines passes through the guide i and
enters the hollow axis m carrying the pulley P which drives the three gear
wheels fixed to the hawl pulleys p secured to the. piece o thence passing over the
guide pulleys g 9 g along and up the flyer F through the guide and the duct d
formed in the journal jover the hawl pulleys p' the guide pulleys 9* 9 in order.
to be wound on the bobbin B after having been regulated by the usual winding
regulator or slide g which is merely outlined on the drawings and is driven by the.
toothed wheel w³.

page_text: The pulley P¹ drives the flyer F and turns in a reverse direction to the pulley P.
In the flyer shewn in Fig. 7. F is the outer flyer and f the inner flyer mounted
on the inner boss of the central part of the left hand end bridge and keyed
loosely at the left hand end of the carrier journal this inner flyer rotating in
the same direction as the carrier but in a reverse direction to that of the outer
flyer F and carrying with it parts of the gearing for driving the hawl pulleys etc.
The driving pulley P¹ drives the flyer F which imparts with the aid of the
bridge b' the pin the arm a¹ and the gear wheels w² (by the last wheel 10 Fig. 8^)
a motion to the hawl pulleys p' to the slide and to the bobbin B.
The driving pulley P' is mounted on an axis a turning loosely in the end of the
flyer F and imparts with the aid of the gear wheels to a motion to the inner
Hver f
A guide is fixed to the bridge b' and another in front of the flyer as in Fig. 1,
so that it will be readily understood that with this last described arrangement
three twists are imparted to the yarn or sliver two inside and the one outside.
The other or right end of the flyer F is of similar construction to the corre-
sponding end of the flyer shewn in Fig. 1 with this difference, that on the boss of
the right hand bridge is mounted the other end of the whole flyer instead of that
of half a flyer.
Although in the arrangement shewn in Fig. 7 I have made use of two
pulleys P P the first driving the flyer F and the second the flyer f I may also
impart with the aid of suitable gear by means of the pulley P' only a motion to the
flyer fin a reverse direction to that of the flyer F.
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
