JAMES ENGELBERT VANNER, of Coleman Street, in the City of London. "IM-
PROVEMENTS IN SILK WINDING MACHINERY."
This Invention has for its object improvements in silk winding machinery.
Machinery as now generally constructed for winding silk on to bobbins consists
of a long horizontal shaft having circular discs mounted upon it at a distance of
a few inches apart. Above the discs are mounted the spindles which carry the
bobbins upon which the silk is to be wound, and upon each spindle is a small
wheel which rests upon the circumference of one or other of the discs, and is thereby
revolved by it; the ends of each spindle are received into vertical slots formed
down the sides of cross bars, which form part of the fixed frame of the machine,
and the spindles are thereby held in place parallel with the long shaft upon which
the friction discs are mounted. The threads coming from the skeins are led through
eyes which are carried by a bar to which a traversing to-and-fro motion is given to
cause the threads to be laid evenly on to the bobbins. It is frequently required
that the silk should be wound more tightly on to bobbins than is practicable when
winding the silk off from skeins. In this case the bobbins are taken to another
machine, and the silk is wound off from them on to other bobbins.
According to my Invention I construct machines of the class above described in
such manner that silk may not only be wound on to bobbins from skeins, but
also so that the rewinding of the silk from one bobbin to another may be
carried on in the same machine. This I effect in the manner shown in the diagram
Drawing hereunto annexed.
In this Drawing a is a long shaft carrying the friction driving discs b; c, c, are
spindles to carry the bobbins on to which the threads are wound as they come
from skeins; d, d, are wheels on the bobbin spindles to rest upon the friction discs b;
e, e, are vertical slots in cross bars into which the ends of the spindles c are

page_text: received; g¹ are thread eyes upon a traversing bar g; the threads passing on to the
bobbins are led through these eyes and are by them laid evenly on to the bobbins.
When the silk has to be rewound from the bobbins on the spindles c on to other
bobbins, the spindles c with the full bobbins upon them are dropped into notches f¹
in the cross bars f, and the thread is led from them to other bobbins upon spindles
h which are driven from the friction discs b in the same manner as the spindles c.
The required tension is placed upon the bobbins from which the silk is being
unwound in any suitable manner. With this arrangement it is unnecessary that
the threads which are being wound from one bobbin to another should be passed
through traversing thread eyes, as the threads being laid correctly upon one bobbin
will lay themselves correctly on the bobbins on to which they are being rewound.
The machine may be constructed with two shafts a and driving discs b as is
usual, or the machine may be made single.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by the
said James Engelbert Vanner in the Great Seal Patent Office on the 28th
April 1877.

PROVEMENTS IN SILK WINDING MACHINERY."
"IM-
This Invention has for its object improvements in silk winding machinery.
Machinery as now generally constructed for winding silk on to bobbins consists
of a long horizontal shaft having circular discs mounted upon it at a distance of a
few inches apart. Above the discs are mounted the spindles which carry the
bobbins upon which the silk is to be wound, and upon each spindle is a small
wheel which rests upon the circumference of one or other of the discs, and is
thereby revolved by it; the ends of each spindle are received into vertical slots
formed down the sides of cross bars which form part of the fixed frame of the
machine, and the spindles are thereby held in place parallel with the long shaft
upon which the friction discs are mounted. The threads coming from the skeins
are led through eyes which are carried by a bar to which a traversing to-and-fro
motion is given to cause the threads to be laid evenly on to the bobbins. It
is frequently required that the silk should be rewound. In this case the bobbins
are taken to another machine or to another part of the same machine, and the
silk is wound off from them on to other bobbins. According to my Invention I
construct machines of the class above described in such manner that silk may not
only be wound on to bobbins from skeins, but also so that the rewinding of the silk
from one bobbin to another may be carried on in the same machine, and the same
driving discs be used for giving motion to both sets of bobbins. This I effect in the
manner shewn in the diagram Drawing hereunto annexed.
In this Drawing a is a long shaft carrying the friction driving discs b. The discs
are arranged at intervals along the shaft such that the bobbins may be received
between them; c, c, are spindles to carry the bobbins on to which the threads are
wound as they come from skeins; d, d, are wheels on the bobbin spindles to rest
upon the friction discs b; e, e, are vertical slots in cross bars finto which the
ends of the spindles c are received; g¹ are thread eyes upon a traversing bar g, the
threads passing on to the bobbins are led through these eyes and are by them laid
evenly on to the bobbins. When the silk has to be rewound from the bobbins on
the spindles con to other bobbins, the spindles c or other spindles with the full
bobbins upon them are dropped into notches f¹ in the cross bars f, and the thread
is led from them to other bobbins upon spindles h which are driven from the
friction discs b in the same manner as the spindles c.
The required tension is placed upon the bobbins from which the silk is being
unwound in any suitable manner. With this arrangement it is unnecessary that
the threads which are being wound from one bobbin to another should be passed

page_text: through traversing thread eyes, as the threads being laid correctly upon one bobbin
will lay themselves correctly on the bobbins on to which they are being rewound.
The machine may be constructed with two shafts a and driving discs b as is usual,
or the machine may be made single.
Having thus described the nature of my said Invention, and the manner of
performing the same, I would have it understood that I claim the construction of
machinery for winding and rewinding silk, substantially as described.
In witness whereof, I, the said James Engelbert Vanner, have hereunto set
my hand and seal,. this Twenty-eighth day of April, in the year of our Lord
One thousand eight hundred and seventy-seven.
