Scaled the 11th June 1880, and dated the 15th December 1879.
PROVISIONAL SPECIFICATION left by the said John Charlesworth and
William Butterfield at the Office of the Commissioners of Patents on the 15th

This Invention has reference to machinery for spinning and twisting yarn direct
from the doffer of a condensor carding machine, by which means we dispense with
the machine known as the mule.
The improvements consist in passing the yarn or thread (after leaving the doffer)
through a pair of rubbing belts or rollers, from whence it passes between two pairs
of drawing rollers placed at a suitable distance apart, then through guide eyes, and
is wound on to bobbins or spindles. The bottom roller of one pair of drawing
rollers is recessed or grooved, so that at certain parts of its revolution the top roller
will not touch its surface, but will allow twist to get into the yarn between the
spindle and back drawing rollers. The rings and flyers in connection with the
bobbins and spindles are raised up and down in the ordinary manner, but for
forming the cop we attach a screwed boss on the lifting 10d, by which means, and
by a pair of wheels or worm and pinion, the boss is gradually raised up the lifter
rod, and the cop is built or formed thereby into the proper shape.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said John Charlesworth and William Butterfield in the Great Seal Patent
Office on the 15th June 1880.
JOHN CHARLESWORTH, of Linthwaite, near Huddersfield, in the County of York,
and WILLIAM BUTTERFIELD, of the same Place. "IMPROVEMENTS IN SPINNING AND
IN MACHINERY OR APPARATUS EMPLOYED THEREIN."
This Invention has reference to machinery for spinning and twisting yarn direct
from the doffer of a condenser carding machine, by which means we dispense with
the machine known as the mule.

page_text: The improvements consist in passing the yarn or thread (after leaving the doffer)
through a pair of rubbing rollers, from whence it passes over rollers and between
rubbing belts, then through guide eyes, and is wound on to the bobbins or
spindles.
In order that this Invention may be better understood we will now proceed to
describe the accompanying Sheet of Drawings illustrative thereof. A is the
ring doffer of an ordinary condenser carding machine, and B are the strippers which
receive from the doffer the narrow width of fibre known as the condenser threads,
and B' is the divider for dividing the said threads. The threads then pass between
the rubbing rollers C, which have an oscillatory motion given to them, and over the
rollers D, and between endless rubbing belts E, and over the rollers F through
guide eyes G, and is wound onto the bobbins H by the rings and flyers.
The rubbing belt E will be better understood on reference to detail, Fig. 2, which
consists of an endless belt passing around rollers e at each end.
It will be seen that as the thread is passing between two leathers, which are
running in opposite directions, that any quantity of twist (according to the speed
given to the belt) may be put into the yarn. The requisite draught for drawing
the yarn is obtained between the rubbing rollers C and bobbins H. In order
that the bobbins may be removed from off the spindles the guide eyes G are
hinged at g, so that they may be lifted out of the way, as shewn at J. The lifting 1
rails K and L, employed for forming or shaping the cops, are connected together by
the rod M, such rod being connected to chain N, passing over pulley P. The
requisite rotary motion is given to the pulley by rack and pinion Q (see Fig. 3),
operated by lever R and cams S. The tapering or nosing motion is obtained
through the screwed shafts T entering the bosses U, which are caused to revolve a
by means of ratchet wheel operated by rod V and worm and wheel W, which
lengthens or shortens the distance between the rack Q and lever R, and consequently
the movement of the rack is varied.
We have shewn three rows of spindles, but more or less may be employed, and
although we have shewn them driven from two cylinders W, ✗, other methods of
driving the spindles may be employed. Fig. 3 is pard end view, and Fig. 4 is part
front elevation of our improved machine, shewing some of the means of driving the
various parts.
Having thus described the nature and particulars of our Invention and the
manner in which the same is to be performed, we would have it understood that 3
we do not confine ourselves to the number or positions of the spindles or to the
manner of driving the same, as other mechanical arrangements may be adopted
without departing from the main features of the Invention, but what we consider to
be new and claim as our Invention is,―
Firstly. The use and employment of apparatus for spinning condenser threads
direct from the doffer, substantially as herein shewn and described.
Secondly. The use and employment of the endless rubbing belt E for giving twist
to the yarn, substantially as herein shewn and described.
In witness whereof, I, the said John Charlesworth, for and on behalf of myself
and the said William Butterfield, have hereunto set my hand and seal, this
Twelfth day of June, in the year of our Lord One thousand eight hundred
and eighty.
