Im- PROVEMENTS IN MAKING UP FOR SALE OR USE SEWING THREAD OF COTTON, LINEN, OR SILK.”
Year: 1874

page_text: LETTERS PATENT to Robert Kerr, of Paisley, in the County of
Renfrew, North Britain, Manufacturer, for the Invention of “Im-
PROVEMENTS IN MAKING UP FOR SALE OR USE SEWING THREAD OF COTTON,
LINEN, OR SILK.”
PROVISIONAL SPECIFICATION left by the said Robert Kerr at the
Office of the Commissioners of Patents, with his Petition, on the
26th September 1874.
I, ROBERT KERR, of Paisley, in the County of Renfrew, North
5 Britain, Manufacturer, do hereby declare the nature of the said In-
vention for "IMPROVEMENTS IN MAKING UP FOR SALE OR USE SEWING THREAD
OF COTTON, LINEN, OR SILK," to be as follows, that is to
say:-
This Invention relates to an improved mode of making up sewing
thread of cotton, linen, or silk, so as to be more convenient for sale and

page_text: more advantageous in use than such thread when put up as heretofore
on bobbins or spools.
When thread is put up on bobbins or spools it is often fatigued and
unequally strained and loses its roundness, added to which there is often
much uncertainty as to the exact quantity put on a bobbin or spool. 5
When using such thread in sewing machines and otherwise, the bobbin
or spool has to rotate and offers very unequal resistance, from variation
of diameter and other causes.
By the present Invention the defects and inconveniences referred to
are completely obviated by finally winding the finished sewing thread in 1
the form of cops, as practised in winding weaving yarns for the
shuttle. Such cops may be wound on short or long tubes of paper,
wood, or other suitable material, or they may be wound without any
central tubes.
When tubes are used they may be arranged to project from the 1
bottom of the cop, and have the quality and maker's name marked or
printed on the projecting part.
In the formation of the cop the thread is wound in conical layers,
and can be drawn off from the pointed end without turning the cop,
without becoming entangled, and without presenting more resistance at 2
one part than at another.
Sewing thread made up in the improved manner will occupy con-
siderably less bulk than when upon bobbins or spools, and not only will
the cost of the bobbins and spools be saved, but there will also be a
considerable saving in freight or carriage.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROBERT
KERR, of Paisley, in the County of Renfrew, North Britain, Manu- 30
facturer, send greeting.

NOW KNOW YE, that I, the said Robert Kerr, do hereby declare
the nature of my said Invention, and in what manner the same is to bo
performed, to be particularly described and ascertained in and by the
following statement in writing, that is to say:
-
My said Invention relates to an improved mode of making up sewing
thread of cotton, linen, or silk, so as to be more convenient for sale and
more advantageous in use than such thread is when put up as heretofore
on bobbins or spools.
When thread is put up on bobbins or spools it is often fatigued and
0 unequally strained and loses its roundness, added to which there is often
much uncertainty as to the exact quantity put on a bobbin or spool.
Also when using such thread in sewing machines and otherwise, the
bobbin or spool has to rotate and offers very unequal resistance, from
variation of diameter and other causes.
By my Invention the defects and inconveniences referred to are

page_text: or use in the form obtained by winding it in conical layers, as herein-
before described.
In witness whereof, I, the said Robert Kerr, have hereunto
set my hand and seal, this Nineteenth day of March, in the
year of our Lord One thousand eight hundred and seventy-
five.
