IMPROVEMENTS RELATING TO COP TUBES
Year: 1861

page_text: LETTERS PATENT to Thomas Hamilton and James Hamilton, both of
Glasgow, in the County of Lanark, North Britain, Bobbin Turners, for
Sealed the 3rd December 1861, and dated the 6th June 1861.
PROVISIONAL SPECIFICATION left by tho said Thomas Hamilton and
James Hamilton at the Office of the Commissioners of Patents, with
their Petition, on the 6th June 1861.
We, THOMAS HAMILTON and JAMES HAMILTON, both of Glasgow, in the
County of Lanark, North Britain, Bobbin Turners, do hereby declare the
nature of the said Invention of "IMPROVEMENTS RELATING TO COP TUBES," to be
as follows, that is to say:-
This Invention has principally for object to give increased strength to cop
tubes or holders for the bottoms of cops or wound-up yarn, and it consists in
winding upon wooden or other tubular cores one or more layers of thread.
yarn, wire, tape, or strips of cloth, paper, leather, or such like material, such
external layers being secured to and forming part of the finished cop tube.
It is preferred to make the tubular cores of wood, according to the Speci-
fication of Letters Patent granted to the present applicants, and dated the
19th January 1858 (No. 81), or otherwise; but it is desirable to make the
part to receive the external binding thread or other covering slightly smaller
than the extreme ends. The thread may be wound on by hand, or by self-

page_text: acting or partly self-acting mechanism, such as is in use for filling spools or
bobbins. The loose end of the thread at starting is, according to one modi-
fication, laid along the tube, being held by the succeeding convolutions of the
thread. The winding mechanism may be contrived to lay this starting end in
an indentation, so as not to cause the thread passing over it to be raised. The
finishing end of the thread is secured in a nick formed in the end of the tube,
and by way of extra security and finish, a slight coat of varnish or composition
may be subsequently applied to the whole, or such varnish or composition may
be applied to the thread as it is being wound on. The external binding
covering may be applied to tubes of paper, gutta percha, and other materials
requiring strengthening; and as the thread surface is better than the ordinary
smooth surface for holding the cop, it may be applied with advantage, as, for
example, upon metal tubes, where the extra strength it gives is not an object.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thomas Hamilton and James Hamilton in the Great Seal
Patent Office on the 4th December 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, THOMAS
HAMILTON and JAMES HAMILTON, both of Glasgow, in the County of Lanark,
North Britain, Bobbin Turners, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixth day of June, in the year of our Lord One
thousand eight hundred and sixty-one, in the twenty-fourth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said Thomas Hamilton and James Hamilton, Her special licence that we, the
said Thomas Hamilton and James Hamilton, our executors, administrators, and
assigns, or such others as we, the said Thomas Hamilton and James Hamil-
ton, our 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 RELATING TO
COP TUBES," upon the condition (amongst others) that we, the said Thomas
Hamilton and James Hamilton, our executors or administrators, by an instru-
ment in writing under our, or their, or one of their hands and seals, 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

page_text: 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 we, the said Thomas Hamilton and James
Hamilton, do hereby declare the nature of our said Invention, and in what
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement in writing, reference being had to
the accompanying Drawings, and to the letters and figures marked thereon,
that is to say:-
Our said Invention has principally for object to give increased strength to
cop tubes or holders for the bottoms of cops or wound-up yarn, and it consists
in winding upon wooden or other tubular cores once or more layers of thread,
yarn, wire, tape, or strips of cloth, paper, leather, or such like material, such
external layers being secured to and forming part of the finished cop tube.
It is preferred to make the tubular cores of wood, according to the Speci-
fication of Letters Patent granted to the present applicants, and dated the
19th January 1858 (No. 81), or otherwise; but it is desirable to make the
part to receive the external binding thread or other covering slightly smaller
than the extreme ends.
i
Figure 1 on the accompanying Sheet of Drawings is an elevation of a tubular
wooden core made according to our present Invention; and Figure 2 is a
longitudinal section of the same.
The part a, a, to be covered with thread extends over almost the entire
length of the core, small portions at each end being made slightly larger, as
shown, to retain the thread. Figure 3 is an elevation of the complete cop
tube, that is, the wooden core as bound or covered with thread. The thread
may be wound on by hand, or by self-acting or partly self-acting mechanism,
such as is in use for filling spools or bobbins. The loose end of the thread at
starting is, according to one modification, laid along the tube, being held by
the succeeding convolutions of the thread. The winding mechanism may be
contrived to lay this starting end in an indentation, so as not to cause the
thread passing over it to be raised. The finishing end of the thread is secured
in a nick formed in the end of the tube, and by way of extra security and
finish, a slight coat of varnish or composition may be subsequently applied to
the whole; or such varnish or composition may be applied to the thread as it
is being wound on. The external binding covering may be applied to tubes of
paper, gutta percha, and other materials requiring strengthening; and as the
thread surface is better than the ordinary smooth surface for holding the cop,
it may be applied with advantage, as, for example, upon metal tubes where
the extra strength it gives is not an object.

page_text: Having thus particularly described our said Invention, and the manner in
which the same is or may be used or carried into effect, we have to state that
.we do not restrict ourselves to the precise details herein-before described or
delineated, and that we do not claim the application of other materials than
thread, yarn, or wire, for covering metal cop tube cores; but that what we
consider to be novel and original, and claim as the Invention secured to us
by the herein-before in part recited Letters Patent, is,-
First, the applying of an external binding covering of thread, yarn, wire,
tape, or strips of cloth, paper, leather, or such like material to cop tube cores
of wood, paper, gutta percha, or other like material requiring strengthening,
substantially as herein-before described.
Second, the applying of an external covering of thread, yarn, or wire to cop
tube cores of metal, for the purpose of obtaining an improved holding surface.
for the cop, substantially as herein-before described.
In witness whereof, we, the said Thomas Hamilton and James Hamilton,
have hereunto set our hands and seals, this Second day of December,
in the year of our-Lord-One thousand eight hundred and sixty-one.
THOMAS HAMILTON. (L.S.)
JAMES HAMILTON.
