page_text: LETTERS PATENT to George West Royston Pigott, of Notting Hill,
London, in the County of Middlesex, for the Invention of "Im-
PROVEMENTS IN COVERED WIRE AND IN THE MEANS OR APPARATUS FOR
EFFECTING THE SAME."
"
PROVISIONAL SPECIFICATION left by the said George West Royston
Pigott at the Office of the Commissioners of Patents, with his
Petition, on the 30th January 1872.
I, GEORGE WEST ROYSTON PIGOTT, of Notting Hill, London, in the
County of Middlesex, do hereby declare the nature of the said Inven
tion for "IMPROVEMENTS IN COVERED WIRE AND IN THE MEANS OR APPARATUS
FOR EFFECTING THE SAME," to be as follows:-
This Invention relates to metal wire covered with thread, or having
yarns of cotton, silk, or other fibrous substances, or bands or tapes wound
around it, and the object of the first part is to prevent oxidation or rusting
of the wire, which is effected by first causing it pass through a bath of

page_text: melted tin or zinc, or if iron wire it may pass through a bath of sulphate
of copper or alloy of lead and tin, and subsequently through a solution
of gutta percha, india-rubber, or other insulating or adhesive matters.
Wire thus prepared is then covered with thread or yarn of any suitable
or desirable fibrous substances by the usual means, or by means described
in the second part of this my said Invention, which consists in the employ-
ment of a hollow spindle mounted in a suitable frame, and capable of
rotating at a high velocity, one end of the said spindle projecting and
tapered to receive a bobbin of the thread or yarn to be used as a covering
of the wire, which is caused to pass through the hollow spindle. This
taper part of the spindle is provided with an adjustable collar or washer
at each end, so that the bobbin may be adjusted to fit so as to turn
smoothly, and yet avoid or prevent lateral shake on the spindle. This
spindle also carries a flyer for lapping or winding the thread upon the
wire.
When the wire to be covered is of too great a length to be covered
with one bobbin this flyer may be in two parts laterally, and held
together by a clip, so that it may be removed readily from the spindle for
the purpose of replacing the empty bobbin with a full one, a series of
full ones being first threaded upon the wire in front of or opposite to the
taper end of the spindle. The empty bobbins being in two parts are
readily removed therefrom.
When it is required to apply two different threads to the same wire
one upon the other, another hollow spindle is employed similar to the
former, and placed in line therewith, so that the wire will pass through
& from one spindle and flyer or winding-on apparatus to the other, and
both spindles operated at the same time, each spindle being driven at a
proper relative or suitable speed.
To avoid the use of oil or other lubricant to these spindles I use
lignum vitae wood for the bearings, and may also use it to bush the
bobbins with.
I do not limit myself to the employment of two hollow spindles, as a
series of such spindles may be mounted similarly in line armed with
bobbins, and thus several threads are delivered by them simultaneously
and wound consecutively on the wire.

filed by the said George West Royston Pigott in the Great Seal
Patent Office on the 30th July 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
WEST ROYSTON PIGOTT, of Notting Hill, London, in the County of
Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirtieth day of January, in the
year of our Lord One thousand eight hundred and seventy-two, in the
thirty-fifth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said George West Royston Pigott, Her
special licence that I, the said George West Royston Pigott, my
executors, administrators, and assigns, or such others as I, the said
George West Royston Pigott, my executors, administrators, and assigns,
should at any time agree with, and no others, from time to time and
at all times thereafter during the term therein expressed, should and
lawfully might make, use, exercise, and vend, within the United Kingdom
of Great Britain and Ireland, the Channel Islands, and Isle of Man,
an Invention for "IMPROVEMENTS IN COVERED WIRE AND IN THE MEANS OR
APPARATUS FOR EFFECTING THE SAME," upon the condition (amongst others)
that I, the said George West Royston Pigott, my executors or adminis-
trators, by an instrument in writing under my, or their, or one of
their hands and scals, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to
be performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the
date of the said Letters Patent.
.
NOW KNOW YE, that I, the said George West Royston Pigott, do
hereby declare the nature of my said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained'
in and by the following statement and accompanying Sheet of Drawings
(that is to say:-
This Invention relates to metal wire covered with thread or having
yarns of cotton, silk, or other fibrous substances or bands or tapes wound-
around it, and the object of the first part is to prevent oxidation or
rusting of the wire, which is effected by first causing it to pass through

page_text: a bath of melted tin or zinc, or if iron wire it may pass through a bath
of sulphate of copper or alloy of lead and tin, and subsequently through
a solution of gutta percha, india-rubber, or other insulating or adhesive
matters.
Wire thus prepared is then covered with thread or yarn of any suitable
or desirable fibrous substances by the usual means, or by means described
in the second part of this my said Invention, which consists in the
employment of a hollow spindle mounted in a suitable frame, and
capable of rotating at a high velocity, one end of the said spindle pro-
jecting and tapered to receive a bobbin of the thread or yarn to be used
as a covering of the wire, which is caused to pass through the hollow
spindle. This taper part of the spindle is provided with an adjustable
collar or washer at each end, so that the bobbin may be adjusted to fit
so as to turn smoothly, and yet avoid or prevent lateral shake on the
spindle. This spindle also carries a flyer for lapping or winding the
thread upon the wire.
When the wire to be covered is of too great a length to be covered
with one bobbin this flyer may be in two parts laterally, and held
together by a clip, so that it may be removed readily from the spindle for
the purpose of replacing the empty bobbin with a full one, a series of
full ones being first threaded upon the wire in front of or opposite to the
taper end of the spindle. The empty bobbins being also in two parts
or slotted are readily removed therefrom.
'
When it is required to apply two different threads to the same wire
one upon the other, another hollow spindle is employed similar to the
former, and placed in line therewith, so that the wire will pass through
and from one spindle and flyer or winding-on apparatus to the other,
and both spindles operated at the same time, each spindle being driven
át a proper relative or suitable speed.

"
To avoid the use of oil or other lubricant to these spindles I use
lignum vitae wood for the bearings, and may also use it to bush the
bobbins with.
In order that the said Invention may be clearly understood I herein
give reference to an accompanying Sheet of Drawings illustrative of the
means or apparatus I employ to carry into practical effect the second
part thereof (the first part being sufficiently explained by the foregoing
statement).

page_text: ;
Fig. 1 shews a portion of the hollow spindle A, with wharle A¹ for
driving it, and one of the necks A³, by which it is carried in steps or
bearings of any suitable framework. The projecting end A³ of the said
spindle is tapered so as to readily receive and carry a bobbin B, con-
taining yarn, or bands, or tapes of any desirable substance for covering
the wire C, which is caused to pass through the hollow spindle and
travel at a suitable speed. This' taper part of the spindle is provided
with an adjustable collar or washer D and a spiral spring E, in order that
the bobbin may be adjusted on the spindle to fit so as to turn smoothly,
and yet have sufficient drag or friction and avoid or prevent lateral
sliake on the spindle. The spindle being taper, the bobbin is bored out
taper to fit accurately, as shewn in the Drawings. The spindle also
carries a flyer F for conducting the yarn from, the bobbin and for lapping
or winding the same upon the wire.
"
.
+
When the wire to be covered is. of too great a length to be covered
with one bobbin this flyer may be in two parts laterally (see Figs. 2
and 3), and held together by a clip nut G; so that it may be removed
readily from the spindle for the purpose of replacing the empty bobbin
with a full one, a series of full ones being first threaded upon the wire
in front of or opposite to the taper end of the spindle (see Fig. 4). The
empty bobbins being also in two parts are readily removed therefrom.
Figs. 5 and 6 shew the bobbin in two parts, held together by clips G,
which have an opening at one part to pass over the wire or for it to pass.
through. Or instead of the bobbins and flyer being in two parts they
may have a slit on one side, as shewn at Figs. 7 and 8, for the wire to
pass through.
When it is required to apply two or more different threads to the
same wire, one upon the other, hollow spindles are employed similar to
the former and placed in line therewith, so that the wire will pass
through and from one spindle and flyer or winding-on apparatus to the
other, and both spindles operated at the same time, each spindle being
driven at a proper relative or suitable speed.
$
To avoid the use of oil or other lubricant to these spindles I use
lignum vitae
wood for the bearings, and may also use it to bush the
bobbins with.
"
I do not limit myself to the employment of two hollow spindles, as a
series of such spindles may be mounted similarly in line armed with

page_text: bobbins and flyers, and thus several threads are delivered by them
simultaneously and wound consecutively on the wire, as shewn in
Fig. 9.
In witness whereof, I, the said George West Royston-Pigott, have
hereunto set my hand and seal, this Twenty-sixth day of July,
in the year of our Lord One thousand eight hundred and
seventy-two.
