The object of this Invention is to render it practicable to spin extra hard twisted
or "wig" yarn upon the mule, whereby the same is more cheaply produced than
upon the throstle as hitherto practised.
In accordance with this Invention I take a metallic tube, by preference of steel
or iron, which is split up wholly or partially along one side, so that when the same
is placed upon the spindle or mule it beds firmly along the whole length of the
spindle, and the split or longitudinal opening allows it to yield sufficiently for this
purpose; I am thus enabled to spin and doff the cops with certainty, and without
producing any waste material which ensues to such a large extent when such yarn
is attempted to be spun on the mule upon the ordinary paper cop tubes.

HENRY WHITAKER, of Manchester, in the County of Lancaster. "IMPROVEMENTS
IN AND APPARATUS FOR SPINNING EXTRA HARD TWISTED OR WIG' YARN UPON
THE MULE"
The object of this Invention is to render it practicable to spin extra hard twisted
or "wig" yarn upon the mule, whereby the same is more cheaply produced than
upon the throstle as hitherto practised.
Hitherto many attempts have been made to spin the aforesaid description of yarn
upon the mule, and amongst other expedients ordinary paper cop tubes have some-
times been placed upon the spindles and the cops built upon them, but owing to the
degree of twist and hardness in this description of yarn such paper tubes have so
rapidly become cut up and destroyed by the cutting action of the yarn upon them
that their use has not only become discouraged but also rendered unprofitable.
Again when this extra hard twisted or "wig" yarn has been spun direct upon the
spindles of a mule it has been found impracticable to doff the cops off such spindles
and to introduce the requisite reeling skewer in their place owing to the hard spun
yarn snarling and filling up the central space in the cops previously occupied by the
spindle before it is possible to introduce such skewers.
Now I have found that it is possible to spin this description of yarn upon the
mule by the use and application to the purpose of a thin metallic tube or sheath
(by preference of steel or iron) placed upon each spindle, and upon the outside of
which the cop is formed in the ordinary manner.
This metallic tube is split up
wholly or partially along one side so that when the same is placed upon the spindle
of the mule it beds firmly along the whole length of the spindle, the split or
longitudinal opening allowing it to yield sufficiently for the purpose. I find that
the metallic tube forming the subject matter of Letters Patent granted to me on
November 13th, 1878, Number 4604, is suitable for the purpose of this Invention.
In carrying out my present Invention I place one of these tubes on each of the
spindles of the mule and build the cops direct upon them in the ordinary manner.
I am thus enabled to spin and doff the cops formed of this extra hard twisted or
"wig" yarn with certainty and without producing any waste, whilst the tube itself
forms a means of placing the cop upon the skewer of the reeling machine without
the possibility of snarling, as herein before described.
Having thus particularly described and ascertained the nature of this my said
Invention, together with the best methods with which I am acquainted for
carrying the same into practical effect, I wish it to be distinctly understood that
I claim,―
1st. The improved method of spinning cops of extra hard twisted or "wig" yarn
upon the mule, and of transferring the same to the reeling skewers, as hereinbefore
described.

In witness whereof, I, the said Henry Wkitaker, have hereunto set my hand.
and seal, this 13th day of June, in the year of our Lord One thousand
night hundred and seventy nine
