page_text: LETTERS PATENT to Thomas Unsworth, of Manchester, in the County of
Lancaster, Machinist and Doubler, for the Invention of "IMPROVEMENTS IN
LAYING THE FIBRE OF YARNS OF ALL. DESCRIPTIONS IN SPINNING, DOUBLING,
AND TWISTING, AND DISPENSING WITH THE NECESSITY OF GASING."
PROVISIONAL SPECIFICATION left by the said Thomas Unsworth at the
Office of the Commissioners of Patents on the 23rd March 1876.
THOMAS UNSWORTH, of Manchester, in the County of Lancaster, Machinist and
Doubler. IMPROVEMENTS IN LAYING THE FIBRE OF YARNS OF ALL DESCRIPTIONS
IN SPINNING, DOUBLING, AND TWISTING, AND DISPENSING WITH THE NECESSITY OF
GASING."
I carry the yarn from the back bobbins same as in my former patented cable
laying and banding machines, dated 25th April 1871, No. 1088, over the back
stretching rollers from thence through the bath of water or other mixture, over a
breast bearer with a series of longitudinal strips of india-rubber or other like
material, and to the usual stretching rollers in front of the machine round which
it passes the customary number of times, and taken from the back roller of the front
pair to and over a guide bar covered again by india-rubber or such like material,
and direct as usual to the flyer-eye and bobbin. The yarn being passed from the
bath over the strips of india-rubber or such like material, which has the effect of
laying the loose fluff or fibre before it passes over the last stretching process. The
strands then meet on the india-rubber covering of the guide bar, at which point
the twisting takes place from the flyer. The elastic bond in the india-rubber
embracing it at this point by a sinall nick cht for it to run in, embeds all the
loose fibre which is then twisted in, leaving it as bare and smooth as though it
had been gased without the deteriorating influences of such process, and an extra
strength is thus given to the yarn by the loose fibre being twisted in.
I can and shall apply my improvements to any description of spinning, doubling,
or twisting machine, claiming the laying of fibre by passing of yarn while wet
over or through india-rubber or any such like article previous to twisting, thus
dispensing with the necessity of gasing the yarn.

said Thomas Unsworth in the Great Seal Patent Office on the 23rd September
1876.
THOMAS UNSWORTH, of Manchester, in the County of Lancaster, Machinist and
Doubler. "IMPROVEMENTS IN LAYING THE FIBRE OF YARN OF ALL DESCRIPTIONS
IN SPINNING, DOUBLING, AND TWISTING, AND DISPENSING WITH THE NECESSITY OF
GASING."
Reference being had to the accompanying Drawing, a, a, a, are the back bobbins
same as in my patented cable laying machines b, b, my patented conical stretching
rollers round which the yarn passes from back bobbins a, a, a, and shown by
dotted lines C, C, C, continued as shown from rollers b, b, into trough e, round
glass or other bar G over flannel, cloth, india-rubber, or other equivalently covered
breast bearer H, from thence to the second pair of stretching I, I, up as shown
by dotted lines J over roller or bowl K, down and through nick cut in india-
rubber covered guide bar L, and thence to and over bar roller or pulley, or
through hook M to spindle and flyer N, which puts the twist into the thread.
The trough e contains a mixture of starch and water or its equivalent through
which the yarn passes, thence over breast bearer H, which being covered with
india-rubber, cloth, flannel, or other equivalent, it takes off any surpluss starch or
other material through which it has immediately passed, it then passes over roller or
bowl K, which runs easily, and thence over the front not round india-rubber covered
guide bar L into which it cuts enough to bury itself, the india-rubber embracing
the whole surface of the several threads which are passed over the machine
certainly altogether, but in a untwisted condition by its passage through the
bath e over the breast bearer H, bowl or roller K, which has the effect to some
extent of laying all the loose fluff or fibre in itself before it comes to the last
stretching rollers, after which all the several threads or strands are brought together
and meet in the india-rubber at which point the twisting takes place from the
flyer N. The elastic bond of the india-rubber embracing it at this point presses
all the loose fibre into each strand as it becomes twisted leaving the surface much
smoother than it is possible to get it by the process of gasing. The thread thus
made must of necessity be much stronger by having all its fibrous branches
twisted up with it rather than burnt off as it is by the deteriorating process of
gasing.
I do not confine myself to the precise arrangement I have had occasion to
describe, as I may apply it to any description of machine, and shall have to deviate
from this in detail or arrangement in accordance with the nature and construction
of the machine I have to apply it to, what I claim therefore as secured to me herein
is-
First. The breast bearer H with its appliances or their equivalents for taking
the surpluss materials from the yarn, and partialy laying fibre on leaving the bath c,
substantialy as and for the purposes herein-before set forth.
Second. The bowl or holder K for taking up any slack that may come up, and
for giving it time to partialy dry, substantialy as and for the purposes herein-
before set forth.
Third. The india-rubber covered guide bar L or its equivalent for finaly laying
the fibre, substantialy as and for the purposes herein-before set forth.
In witness whereof, I, the said Thomas Unsworth, have hereunto set my hand
and seal, this Tenth day of September, in the year of our Lord One thou-
send eight hundred and seventy-six
Witness,
JAMES WELCH,
Manchester.
