This invention is an improved machine for wrapping thread, silk and other
workable materials around wire, rod, cord and similar lengths. The said machine
is constructed upon a winding principal, and comprises the following parts:-
A central driving spindle is suitably mounted to work vertically around a hollow
shaft and upon a suitable carrier or base, and upon it is carried a bobbin or reel
which contains the material to constitute the wrapping, the said bobbin being
fixed to the spindle so that it rotates with it but is capable of being disconnected
therefrom when necessary for refilling. Around this bobbin is arranged a fixed
circular track or guide-ring, on which a runner loop is mounted to freely travel,
the said track being preferably carried upon the base or carrier of the machine
and being arranged concentric with the bobbin spindle and shaft so as to surround
them horizontally. The driving spindle, as aforesaid, has a pulley upon it for its
rotation, and the hollow shaft around which it works is of such a length that its
nose end protrudes in an upwardly direction through the end of the spindle above
the bobbin, and its bore is reduced in diameter somewhat to the size of the wire,
rod or cord length to be wrapped. This last named is fed into the machine through
the hollow shaft, and its wrapping takes place just on the point as it issues
through the nose end of the shaft above the bobbin. The exterior diameter of
the hollow shaft is formed with right and left hand helixical depressions, which
lead from a principal oil chamber in the machines base to a smaller oil chamber in
the top part of the driving spindle; their purpose being to thoroughly lubricate
the spindle by conducting the oil from the main chamber up the one helixical
groove to the smaller chamber, and from thence down the other helixical groove
to the lower chamber. The wire to be wrapped does not rotate but remains
stationary, except as regards its longitudinal feed, with the hollow shaft, the
driving spindle and the bobbin being the only rotating central parts.
The end of the wrapping material from the bobbin passed through the runner

page_text: loop which rides on the circular track or guide ring, and is then fastened onto
the end of the wire or rod to be wrapped, and when the driving spindle and
bobbin are rotated the said runner loop is made to travel round its track or ring
by the pull of the wrapping material from the bobbin. In consequence of this
the wrapping material or thread is kept taut or tensioned while being coiled upon
the wire or the like being wrapped, and is paid out from the bobbin only by the
runner loop which rides on a larger diameter over running as it were-the
movement of the bobbin, the said over running being only just sufficient
to nicely adjust the paying out and yet keep the tension on the wrapping
material.

I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors, 11, Burlington Chambers, New Street, in the City
of Birmingham, 6, Lord Street, Liverpool, and 6, Bank Street, Manchester, both
in the County of Lancaster, and 322, High Holborn, in the County of Middlesex,
Civil Engineer, do hereby declare the nature of this invention, (which has been
communicated to me by Joh. Schmidt, of 51, Wilhelm Strasse, Lichtenburg, in
the Empire of Germany, Engineer,) and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:
This invention is an improved machine for wrapping thread, silk, and other
workable materials around wire, rod, cord and similar lengths. The said machine
is constructed upon a winding principal, and comprises the following parts: -
A central driving spindle is suitably mounted to work vertically around a
hollow shaft supported upon a suitable carrier or base, and upon it is carried. a
bobbin or reel which contains the material to constitute the wrapping, the said
bobbin being fixed to the spindle so that it rotates with it but is capable of being
disconnected therefrom when necessary for refilling. Around this bobbin is
arranged a fixed circular track or guide-ring, on which a runner loop is mounted
to freely travel, the said track being preferably carried upon the base or carrier
of the machine and being arranged concentric with the bobbin spindle and shaft
so as to surround them horizontally. The driving spindle, as aforesaid, has a
pulley upon it for its rotation, and the hollow shaft around which it works is of
such a length that its nose end protrudes in an upwardly direction through the
end of the spindle above the bobbin, the bore of the said nose end being reduced
in diameter somewhat to the size of the wire, rod, or cord length to be wrapped.
This last named is fed into the machine through the hollow shaft, and its wrapping
takes place just on the point as it issues through the nose end of 'the shaft above
the hobbin. The exterior diameter of the hollow shaft is formed with right and
left hand helical depressions or grooves, which lead from a principal oil chamber

page_text: in the machines base to a smaller oil chamber in the top part of the driving
spindle; their purpose being to thoroughly lubricate the spindle by conducting
the oil from the main chamber up the one helical groove to the smaller chamber,
and from thence down the other helical groove to the lower chamber. The wire
to be wrapped does not rotate but remains stationary, except as regards its longi-
tudinal feed, with the hollow shaft, the driving spindle and the bobbin being
the only rotating parts.
The end of the wrapping material from the bobbin is passed through the
runner loop, which rides on the circular track or guide ring, and is then
fastened onto the end of the wire or rod to be wrapped, and when the driving
spindle and bobbin are rotated the said runner loop is made to travel round its
track or ring by the pull of the wrapping material from the bobbin. In conse-
quence of this the wrapping material or thread is kept taut or tensioned while
being coiled upon the wire or the like being wrapped, and is paid out from the
bobbin only by the runner loop, which rides on a larger diameter, over-running,
as it were, the movement of the bobbin, the said over-running being just sufficient
to nicely adjust the paying out and yet keep the tension on the wrapping
material.
A machine according to the foregoing is practically illustrated in the accom-
panying sheet of drawings, Fig. 1 being a vertical section and Fig. 2 a top side
plan.
a is the central driving spindle, suitably mounted to work on a base or carrier
around the hollow shaft f, a reel or bobbin, c, containing the material to con-
stitute the wrapping, being carried fixedly upon it so that the said bobbin rotates
with the spindle; the said bobbin however can be disconnected for refilling. A
pulley or drum b is attached to the spindle a for communicating rotary motion
to the said spindle from some source. Around the bobbin c is arranged a fixed
circular track or guide ring d, on which a runner loop e is mounted to travel,
the said loop so fitting the track as to move round upon it fairly free. The said
track is carried upon the base or carrier of the machine and is arranged con-
centric with the bobbin spindle so as to surround it horizontally. The hollow
shaft f, around which the spindle a works, is of such a length at its nose end
as to protrude at the top end of the spindle above the bobbin, and its bore is
reduced in diameter to approximately the size of the wire, rod or cord length g to
be wrapped.
This last named is fed into the machine upwardly through the
hollow shaft f, and its wrapping takes place just on the point issuing from the
noze end of the shaft, as aforesaid. The exterior diameter of the shaft f is formed
with right and left hand helical depressions or grooves 7, which lead from the
principal oil chamber k in the machines base to a smaller oil chamber m in the
top part of the driving spindle; the purpose of the said depressions being to
carry oil up and down from the one oil chamber to the other to thoroughly
lubricate the spindle.
The wire or cord length g does not rotate but has a longitudinal feed up the
hollow shaft f, the said feed being either mechanical or automatic, the latter by
reason of the windings.
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:-
First. A wrapping machine characterised by a driving spindle carrying a bobbin
or reel, a fixed track or guide ring concentric with said spindle and hobbin, a
runner loop travelling upon said track, and a hollow shaft or its equivalent
disposed central to the track and through which the wire, rod or cord length is
fed, all operating substantially as described.
Second. A wrapping machine having in its combination a driving spindle a
carrying a bobbin, a fixed track or guide ring d disposed concentric with said
spindle and bobbin, a runner loop travelling upon said track, and a hollow
e

page_text: shaft disposed central to the said track and through which the wire rod or cord
length is fed, the whole of the parts being constructed for operation substantially
as described and set forth.
Third. A wrapping machine constructed arranged and fitted in the manner
set forth in Figs. 1 and 2.
