PROVISIONAL SPECIFICATION.
Improvements in Wire Covering Machines.
I. ANTON KREIDLER, of 52, Boblingerstrasse, Stuttgart, Wurtemburg, in the
German Empire, Manufacturer, do hereby declare the nature of this invention
to be as follows:-
In the operation of covering wire by winding thereon threads of textile material
india-rubber, paper or other material, it has heretofore been the practice either
to cause the wire to advance with a simple longitudinal motion whilst causing
round the wire, or to cause
the winding reel carrying the covering threads to run
the wire to simultaneously advance and rotate whilst the covering threads were
drawn from a bobbin supported upon a stationary axis.
In order to obtain a really good result, it is of the greatest importance that
the winding should be performed at a high speed, since otherwise, when several
threads are simultaneously wound upon the wire these threads are apt to become
entangled and not to be laid evenly close to one another. In both the above
mentioned kinds of winding machines, however, a limit of speed is soon reached,
such limit being determined by the impossibility of accelerating indefinitely the
movements of the rotating bobbins. For in the former case" not only do the
forms generated tend to obstruct the movement of the filaments but with increased
speed the parts of the machine are subjected to injurious strains which it becomes
impossible to meet. And it will be apparent that the difficulties thus caused will
be increased if, instead of the bobbin which carries the covering threads, the
bobbins which respectively feed and take up the wire are caused whilst the feeding
proceeds to rotate about an axis concentric with that of the wire. This will be
at once obvious, when it is considered that one revolution about their own axes
of the bobbins which respectively feed and take up the wire corresponds to a
very great number of revolutions, around the axis of the wire of the frames
carrying those bobbins.
My present invention consists essentially in a combination of the two arrange-
ments above mentioned.
In my improved machine the bobbin from which the wire to be covered is
drawn and that upon which the wire when covered is wound, are both mounted
in revolving frames whose axes are in alignment with one another, the axes of
the bobbins being perpendicular to those of the frames, and the wire
being led from the one frame to the other through apertures formed in their
respective axes. Between the two frames, a bobbin carrying the covering material
is mounted to rotate around the wire in a direction opposite to that in which
the wire itself revolves, the combined effect of the two rotations in opposite
directions being to virtually increase the speed of the winding operation, so that
in this manner I am enabled to obtain a highly efficient machine.
In the accompanying drawings, illustrating the construction of my improved
machine Figure 1 is a front elevation and Figure 2 a plan view of the machine.
The machine comprises a framework consisting of standards a a and a table b
supporting bearings in which two frames c and d are mounted to rotate, their
rotation in the same direction and at equal speed being effected by the belt
pulleys and f. On the frame c is mounted the feed bobbin s carrying the
wire to be covered and also a brake adapted to ensure a uniform speed of
rotation of the feed bobbin.

page_text: The wire is led from the bobbins through the tubular axis g of the frame c
and thence through the hollow shaft of the spinning runner h, the said shaft
being caused, by means of cord pulley o, to rotate in the direction opposite to that
in which the frame c revolves. By this arrangement, the covering of the wire
with the winding material is effected at this spot. The wire thus covered is
thence drawn in the usual manner through the tubular axis of the second
frame d, and is wound on the taking-up bobbin by the aid of a draft roller k
and a thread guide as usual.
The velocity of the draft roller k is determined by means of differential gearing
consisting of an interchangeable belt pulley m and spur wheel on the axis
of the frame d, a spur wheel on shaft p (rotating with and parallel to the axis
of the frame) a worm on said shaft and worm wheel on the draft roller shaft.

Improvements in Wire Covering Machines.
I, ANTON KREIDLER, of 52, Boblingerstrasse, Stuttgart, Wurtemburg, in the
German Empire, Manufacturer, 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:-
In the operation of covering wire by winding thereon threads of textile material
india-rubber, paper or other material it has heretofore been the practice either
to cause the wire to advance with a simple longitudinal motion whilst causing
the winding reel carrying the covering threads to rotate about the wire, or to cause
the wire to simultaneously advance and rotate whilst the covering threads were
drawn from a bobbin supported upon a stationary axis.
In order to obtain a really good result, it is of the greatest importance that
the winding should be performed at a high speed, since otherwise, when several
threads are simultaneously wound upon the wire these threads are apt to become
entangled and not to be laid evenly close to one another. In both the above
mentioned kinds of winding machines, however, a limit of speed is soon reached,
such limit being determined by the impossibility of accelerating indefinitely the
movements of the rotating bobbins not only in consequence of the resistance
encountered by the filaments, but also by reason of the fact that with increased
speed the parts of the machine are subjected to injurious strains which it becomes
impossible to meet. And it will be apparent that the difficulties thus caused will
be increased if, instead of the bobbin which carries the covering threads, the
bobbins which respectively feed and take up the wire are caused whilst the feeding
proceeds to rotate about an axis concentric with that of the wire. This will be
at once obvious, when it is considered that one revolution about their own axes
of the bobbins which respectively feed and take up the wire corresponds to a
very great number of revolutions, around the axis of the wire of the frames
carrying those bobbins.
My present invention consists essentially in a combination of the two arrange-
ments above mentioned.
In my improved machine the bobbin from which the wire to be covered is
drawn and that upon which the wire when covered is wound, are both mounted
in revolving frames whose axes are in alignment with one another, the axes of the
bobbins being perpendicular to the axes of rotation of the frames, and the wire

respective axes. Between the two frames, a bobbin carrying the covering material
is mounted to rotate around the wire in a direction opposite to that in which
the wire itself revolves, the combined effect of the two rotations in opposite
directions being to virtually increase the speed of the winding operation, so that
in this manner I am enabled to obtain a highly efficient machine.
standards
In the drawings filed with my Provisional Specification, which illustrate the con-
struction of my improved machine, Figure 1 is a front elevation and Figure 2 a plan
view of the machine. The machine comprises a framework consisting of
and a table supporting bearings in which two frames c
and are rotated in the same direction and at equal speed by the belt
pulleys and f. On the frame is mounted the feed bobbin s carrying the
wire to be covered and also a brake adapted to ensure a uniform speed of
rotation of the feed bobbiu.
The wire is led from the bobbins through the tubular axis y of the frame c
and thence through the hollow spindle of the revolving bobbin carrier h, the
said spindle being caused, by means of a crossed belt driven from pulley o, to
rotate in the direction opposite to that in which the frame revolves. Upon
the carrier h is mounted the bobbin from which the material with which the
wire is to be covered, is drawn, the material being led through a guide and
wound upon the wire at this spot. The wire thus covered is thence drawn in
the usual manner through the tubular axis of the second frame d, and is wound
on the taking-up bobbin by the aid of a draft roller and a guide to which a
traversing motion is imparted for laying the wire evenly on the bobbin as usual.
The velocity of the draft roller k is determined by means of differential gearing
consisting of a belt pulley m and spur wheel n on the axis of the frame d, a
spur wheel on shaft (rotating with and parallel to the axis of the frame) a
worm on said shaft and worm wheel r on the draft roller shaft.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is
1. In a machine for covering wire or the like, the combination of a rotating
feed device for the wire to be covered, a rotating take-up device travelling in
the same direction and at the same rate of speed as the feed device, means for cover-
ing the wire and mechanism for rotating the wire covering means in one direction
and for rotating the feed and take-up devices in an opposite direction, whereby
the wire will be rotated in one direction without being twisted and the covering
material will be rotated in an opposite direction.
2. In a machine for covering wire or the like, the combination of a rotating
feed device for the wire to be covered, a rotating take-up device travelling in
the same direction and at the same rate of speed as the feed device, rotating means
for covering the wire, the axes of revolution of said feed and take-up devices
and wire coverine means being substantially in alignment and mechanism for
rotating the wire covering means in one direction and for rotating the feed
and take-up device in an opposite direction, whereby the wire will be rotated
in one direction without being twisted and the covering material will be rotated
in an opposite direction.
