Improvements in or relating to Machines for Preparing and
Spinning Fibres.
J, PAUL BINDSCHEDLER, of 121 Kaiserstr., Wurttemberg, Reutlingen,
Germany, Spinner, 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 flyer frames in which the ordinary curved cones are
replaced by two straight cones.
In this case however, the application of a second differential wheel-work is
necessary in order to obtain the proper movements.
By way of explanation, the laws of motion for the spool and carriage are
expounded in the following lines. It being first assumed that the fly remains still
and the spool wound up.
Let r represent the radius of the empty spool, d the thickness of a layer n the
number of layers to be wound up, then the revolutions of the spool following one
another are proportionate to the expressions :
if the conditions, that equal lengths are wound up in equal. times is fulfilled the
speeds of the carriage succeeding one another must also be proportionate to the
same expressions. Under the above assumption the law of the spool is therefore
the same as that of the carriage.
It is now assumed that the Hy and spool are revolving.
Under this assumption the law of the carriage remains the same, but the law of
the spool changes; to the number of revolutions of the spool which would be
required when the fly remains still; to wind up properly must now be added the
number of revolutions of the fly in such a manner that the number of revolutions
succeeding one another are now proportionate to the expressions :

page_text: Thus one could take the law of the carriage from the driven cone by means of
ordinary gearing and easily obtain the law of the spool by means of differential
gear.
In this machine however this is not the case it rests upon another arrangement
which is represented together with the gear wheels belonging to it in the following
drawings
Fig. 1, represents the connection of the pair of cones with the differential wheel
works, as well as the transfer of the movement to the carriage or lifting rail and
the spool.

A suitable factor.
The driving cone (A) sets in motion by means of a strap (B), the driven
cone (C). The bevel wheel (D) of the first differential work rests firmly on the
axle of said cone (C) and gears with two bevel wheels (E) and (E), the axle of
which carries the large differential wheel (F). The fourth wheel (G) of this
differential wheel work, rests loosely upon the axle of the driven cone (C) and
receives a movement from the wheel (H) by means of a second intermediate
wheel (I). Out of these two rotating factors the wheel (G) and the wheel (D) a
motion is given to the differential wheel (F) which by means of the intermittent
wheel (K) imparts alternate or changing movements, through the wheels (L), to
the carriage or lifting rail.
On the other hand an intermediate wheel (M) transfers the movement of the
differential wheel (F) to the spur wheel (N) which rests loosely on the axle of the
driving cone (A) but is firmly connected with the bevel wheel (0) of the second
differential wheel-work, so that (N) and (O) can revolve independently of the axle
of the cone (A). The bevel wheel (O) meshes with two other bevel wheels (P)
and (P) the axle of which supports the differential wheel (Q). Both these bevel
wheels (P) and (P) engage with the bevel wheel (S) which is fixed upon the axle
of the cone (A). Out of the motion of the bevel wheel (S) and the bevel
wheel (O) arises a motion of the differential wheel (Q), this motion is transferred
by means of an intermediate wheel (U) to the wheel (T) which rests loosely upon
the shafts of driven cone and is firmly connected with the wheel (V). From the
latter the spool receives its movement by means of appropriate intermediate pieces:
in this way, for one revolution of the driving cone, by shifting the strap in equal
distances the following expressions are obtained, for the revolutions of the driven
cone.

page_text: If now 1 is added to each of these expressions we obtain ;
but this is the law of the carriage or lifting rail already referred to many times.
In order to eliminate the addition of 1 the differential wheel (F) is brought into
use (see Fig. 1). The wheel (F) thus moves exactly like the driven cone of an
ordinary machine. It is therefore clear that the sum of both the constant numbers
of revolution added to the revolutions of the differential wheels (F) and (Q) is
larger than that of an ordinary machine, this is easily perceived if we consider
that the wheel (Q) adds exactly the same number of revolutions as the differential
wheel of an ordinary machine, to this are to be added the revolutions of (F) which
are not obtained in an ordinary machine.
The cones are thus constructed that the large end radius represents a suitable
multifold of radius R of the full spool amounting therefore to m R; whilst the
small end radius represents the same multifold of radius r of the empty spool.
i.e., mr.
As a shifting of the strap takes place n - 1 times along the total length of the
cones it is only necessary in order to determine the increase or decrease of the
radius of the cones, to divide the formula:

page_text: If the speed, of the strap of the machine, shewn in the drawings, is supposed to
be equal with that of an ordinary machine, the relief of the strap results as
follows;
cones having the following sizes :
Large radius Rm
=
Small radius = rm
m = a factor sufficiently correct
Rthe radius of a full spool, last layer,
r
=
the radius of the empty spool
together with the use of differential gearing substantially as and for the purposes
herein set forth and as illustrated in my drawings.
