Spinner, for an Invention of "IMPROVEMENTS IN APPARATUS FOR SPINNING,
DOUBLING, AND PREPARING COTTON, WOOL, FLAX, SILK, OR OTHER FIBRES."

JOHN BASTOW, of Bradford, in the County of York, Spinner. "IMPROVEMENTS
IN APPARATUS FOR SPINNING, DOUBLING, AND PREPARING COTTON, WOOL, Flax,
SILK, OR OTHER FIBRES."
The improvements relate to what is known as "cap spinning," and the objects
thereof are to obtain greater uniformity of spin or twist, and to enable a longer
length to be spun on one bobbin than is usually done with the method now in use:
To accomplish this and to effect my improvements I so construct apparatus that
it will vary the speed of the roller or rollers delivering the fibre to the cap spindles,
as the amount of yarn, or the diameter on the bobbins or tubes thereof, is increased
by the winding on process; by which moans the proportion of speed of delivery
to the speed of the spindles is caused to vary according to the thickness or diameter
of yarn upon the bobbin or tube, thereby making it possible to spin a longer length
of yarn on one bobbin without the same relatively varying strain on the yarn as
at present obtains. The improvements also are applicable to the spinning of cops,
on the same class of machinery, by causing the speed of the roller or rollers to
deliver the yarn to the "cap "spindles at varying speeds, according as the yarn is
traversed from the base to the nose of the cop. The arrangement of apparatus for
this purpose can be varied, but I prefer to fix, in any convenient position, a pair of
suitably formed driving cones, which shall act as an intermediate gearing between
the driving shaft and the wheels actuating the delivery rollers, one cone to bo
suitably geared to the driving shaft, and the other to the delivery rollers aforesaid,
with a driving strap from one cone to the other. This same driving strap is passed

page_text: through a suitable guide, which is connected by means of lever or other arrange-
ment to the traversing motion in such manner that in case of cop spinning the
strap connecting the cones is traversed the required distance for a sufficient
variation of speed to be communicated to the delivery rollers as the yarn is moved
from the base to the nose of the cop, and vice versa; and in the case of spinning
on bobbins the same strap guide is connected with a ratchet and pawl motion, or a
clutch and friction motion, or other mechanical equivalent thereto, whereby the
strap is moved a proportionate distance at every traverse of the yarn, or as the
thickness or diameter of the bobbin is increased. This varying speed of the
delivery rollers, for the purpose already described, can be applied to the spinning, 1
doubling, or preparing of cotton, wool, flax, silk, or other fibres.

JOHN BASTOW, of Bradford, in the County of York, Spinner. IMPROVEMENTS
IN APPARATUS FOR SPINNING, DOUBLING, AND PREPARING COTTON, WOOL, FLAX,
SILK, OR OTHER FIBRES."
The improvements relate to what is known as "cap" spinning, and the objects
thereof are to obtain greater uniformity of spin or twist, and to enable a longer
length of yarn to be spun on one bobbin than is usually done with the method
now in use.
To accomplish this and to effect my improvements I construct apparatus in
such manner that it will vary the speed of the roller or rollers delivering the fibre
to the cap spindles, as the yarn in amount or the diameter thereof on the bobbins
or tubes is increased by the winding on process; by which means the proportion
of speed of delivery to the speed of the spindles is caused to vary according to the
thickness or diameter of the yarn upon the bobbin or tube, thereby making it
possible to spin a longer length of yarn on one bobbin without the same constantly
increasing strain on the yarn as at present obtains.
The improvements also are applicable to the spinning of cops on the same class
of machinery, by causing the speed of the roller or rollers to deliver the yarn to the
cap" spindles at varying speeds according as the yarn is traversed from the base
to the nose of the cop.
"
The arrangement of apparatus for this purpose can be varied, but I prefer to fix,
in any convenient position, a pair of suitably formed driving cones, which shall act
as an intermediate gearing between the driving pulley or shaft and the wheels
actuating the delivery rollers; one cone to be suitably geared to the driving
shaft, and the other to the delivery rollers aforesaid, with a driving strap from one
cone to the other. This same driving strap is passed through a suitable guide,
which is connected by means of lever or other arrangement to the traversing
motion, in such manner that in case of the cop spinning the strap connecting the
cones is traversed the required distance for a sufficient variation of speed to be
communicated to the delivery rollers, as the yarn is moved from the base to the
nose of the cop, and vice versa; and in the case of spinning on bobbins the same
strap guide is connected with a ratchet and paul motion, or a clutch or friction
motion, or other mechanical equivalent thereto, whereby the strap is moved a
proportionate distance at every traverse of the yarn, or as the thickness or
diameter of the bobbin is increased.
This varying speed of the delivery rollers, for the purpose already described, can
be applied to the spinning, or doubling, or preparing of cotton, wool, flax, silk, or
other fibres.
But that the improvements may be better understood I will, by the aid of the
accompanying Drawings, proceed more fully to describe means employed by me.
DESCRIPTION OF DRAWINGS.
Fig. 1 shews an end view, & Fig. 2 a front or back view, as the case may be,
of portions of apparatus employed by me.

page_text: main driving shaft of the machine, on which are affixed the driving pulleys e, e.
The strap b, 61, passes through or under a guide f, f, actuated so as to be capable of
shifting the position of such strap on the cones c, c, and d, d, by means of which
the speed transmitted may be varied.
To effect this in the case of spinning on bobbins, as the yarn is increased thereon,
a tappet or striker g, g, is attached to the traversing rail h, h, or to any other
suitable part of the machine, which tappet is made to strike or push the paul
lever j, j, of the ratchet and paul motion, at every traverse of the yarn, or at any
other suitable interval, by which means the ratchet wheel k, k, is driven forward
the distance required. This ratchet wheel is attached to the lever 1, 1, which is 1
deflected by the ratchet & paul motion, and thus by means of the rod m, m, to
which the strap guide f, f, aforesaid is affixed, controls the position of the strap on
the cones, and thereby varios the speed of the delivery rollers in such manner that
the same shall gradually alter as the bobbin is filled with yarn. In place of the
ratchet and paul motion shewn, a clutch motion, or other equivalent, may be 1
employed.
In the case of spinning cops the variation of speed between the nose and the
body of the cop may be effected in the following manner:-
The lever, is connected at its upper end by me. us of the link n, n, to the
traversing rail h, h, as shown in dotted lines (for which purpose the ratchet & 2
paul would be thrown out of gear), in such manner that the strap b', b', is traversed
to & fro on the cones at every traverse of the yarn on the cop, either with a
uniform or irregular speed of traverse, as determined by the actuating traversing
cam or tappet.
Having now described my improvements and means I adopt in carrying the 2
same into effect, I would have it understood that I do not confine myself to the
exact details shown and described, as variations may be made without departing
from the peculiar character of my Invention,
But what I do claim is,-
1st. The use of cones geared in any suitable manner between the driving shaft 3
and the roller or rollers delivering the yarn to the " caps," in cap-spinning &
doubling machinery, whether in combination or not with other portions of
apparatus shown for the purpose of varying the speed of delivery of fibre to the
caps," substantially as shown and described.
ff
2nd. The use of a ratchet & paul motion, or an equivalent clutch motion, in 3
combination with a lover, whereby the speed of the delivery roller or rollers may
be varied in "cap" spinning machinery, whether through the intervention of cones
or other variable speed motions, in manner substantially as shown and described.
3rd. The combination of the parts for the purpose named, and in manner
substantially as shown and described.
In witness whereof, I, the said John Bastow, have hereunto set my hand
and seal, this Twenty-second day of March, in the year of our Lord One
thousand night hund and night ton
