WE, ROBERT ASHWORTH, of Rochdale, in the County of Lancaster, Engineer,
and SAMUEL STOTT, also of Rochdale, in the County of Lancaster, Cotton
Spinner, do hereby declare the nature of the said Invention for." CERTAIN
APPENDAGES TO AND. IMPROVEMENTS IN MACHINERY FOR PREPARING, SPINNING,
DOUBLING, TWISTING, AND WINDING FIBROUS SUBSTANCES," to, be as follows:-
: 2
Our Invention consists in the construction and application to spinning;
doubling, twisting, and winding machines of an apparatus whereby we are
chabled to take off or doff the bobbins, tubes or spools, or other equivalents
-from their spindles, rods, or tubes. The construction of this apparatus is as

page_text: It consists of a longitudinal spindle or shaft which traverses the whole
length of the machine, and is placed behind the bobbins or spools. This shaft
carries at intervals a number of fingers, in the ends of which a hole is drilled
for the reception of a wire, which also traverses the length of the frame. This
wire is on a level with the bottom part of the bobbins or spools, so that when
it is brought into action by hand or otherwise the wire strikes against the
bobbins, and throws them all off simultaneously intoapocketorreceiverplaced
in front and along the length of the machine. The spindles are so connected
to the lifting bar, and the traverse of this bar is such, that when it is desired
to throw the bobbins off, the spindles are all lowered to admit of their easily
being thrown off.
Our Invention consists also in adapting to these frames an appendage or
apparatus, whereby when the bobbins have been thus thrown off, fresh or empty
bobbins can be placed upon the spindles. To accomplish this object we place
behind the bobbins a longitudinal shaft or spindle carrying a number of fingers,
one finger to each spindle. In the ends of each of the fingers we place a pro-
jecting pin and spring, upon which the empty bobbins are placed, and there
retained until liberated by the putting-on action of the apparatus. When it
is required to place fresh bobbins upon the spindles, this shaft is partially
turned, either by hand or by being placed in connection with the moving
parts of the machine, which thereby brings the bobbins down upon the lifting
plates upon the spindles. This action also liberates the springs which hitherto.
held the bobbins upon the projecting pius, so that when the shaft is restored to
its first position the empty bobbins are all left upon their respective spindles,
and the machine is ready to be put in motion for winding on the thread.
Although we have explained one particular method of carrying this part of
our Invention into effect, we do not confine ourselves to this particular
arrangement, as other methods may be adopted, and found equally effective
in practice; but that what we claim as our Invention is, the doffing or
removing of the full bobbins or spools from off their respective spindles, and
replacing the same by 'empty bobbins by mechanical means.
Our Invention consists, secondly, in an elastic flyer, that is to say, we so
construct the flyer that the legs thereof are formed of an elastic substance,
so that the tops and curled portion of the legs approach each other, and
bear upon the thread as it is laid upon the bobbins, but at the same time
as the diameter of the bobbins increases as the thread is laid, these legs
are forced further apart. By this means the thread is laid tighter upon the
bobbins:
Our Invention also relates to an improved flyer top, and consists in giving

page_text: an extra twist or bend to the flyer legs between the ordinary bend and the
top of the flyer, also in so connecting this flyer that it admits of being readily
removed from off the spindle.

Office on the 30th November 1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, ROBERT
ASHWORTH, of Rochdale, in the County of Lancaster, Engineer, and SAMUEL
STOTT, also of Rochdale, in the County of Lancaster, Cotton Spinner, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirty-first day of May, in the year of our Lord
One thousand eight hundred and fifty-five, in the eighteenth year of Her
reign, did, for Herself, Her heirs, and successors, give and grant unto us, the
said Robert Ashworth and Samuel Stott, Her special licence that we, the said
Robert Ashworth and Samuel Stott, our executors, administrators, and assigns,
or such others as we, the said Robert Ashworth and Samuel Stott, our exe-.
cutors, administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereatter during the term therein
expressed, should and lawfully might make, use, exercise, and vend, within
the United Kingdom of Great Britain and Ireland, the Channel Islands,
and Isle of Man, an Invention for "CERTAIN APPENDAGES TO AND IMPROVEMENTS
IN MACHINERY FOR PREPARING, SPINNING, DOUBLING, TWISTING, AND WINDING
FIBROUS SUBSTANCES," upon the condition (amongst others) that we, the said -
Robert Ashworth and Samuel Stott, or one of us, by an instrument in writing
under our hands' and seals, or under the hand and seal of one of us, should
particularly describe and ascertain the nature of the said Invention, and in
what manner the same was to be performed, and cause the same to be filed
in the Great Seal Patent Office within six calendar months next and imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said Robert Ashworth and Samuel Stott, do
hereby declare the nature of our said Invention, aud in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement thereof, reference being had to the Drawings hereunto
annexed that is to say-

page_text: Our Invention consists, firstly, in the constructionandapplicationtospinning;
doubling, twisting, and winding machines of an apparatus whereby we are
enabled to take off or doff the bobbins, tubes, or spools, or other equivalents,
from their spindles, rods, or tubes.
Our Invention consists also in adapting to these frames an appendage or
apparatus, whereby, when the bobbins have been thrown off or doffed, a fresh
supply of empty bobbins, tubes, or spools can be placed upon the spindles. In
order to receive the bobbins, tubes, or spools, when thrown off or doffed, we
place in front and along the length of the machine a receiver or pocket,
whereby all the bobbins, tubes, or spools are collected simultaneously. The
manner in which we carry this part of our Invention into effect is as follows,
reference being had to the Drawings hereunto annexed, in which similar
letters of reference iudicate similar parts.
Figure 1 represents an elevation of one end of a machine with our improve-
ments adapted thereto, and Figure 2 a section of one half of the machine.
A, A, is the general framework of the machine; B, the roller beam; C, C,
the roller stand; and D, D, the rollers; E, E, the roving bobbins; F, F, the
bobbins; G, the flyers; H, the flyer tubes; I, the lower rail; and K, the lifting
rail. The construction of these parts is similar in all respects to the machine
for which Letters Patent were granted to us of date the Fifth day of
January, One thousand eight hundred and fifty-five, and will therefore
need no further description, so we at once proceed to describe the manner
in which we construct our said apparatus. L is a longitudinal spindle
or shaft which traverses the whole length of the machine, and is placed
behind the bobbins or spools. This shaft carries at intervals a number
of fingers M, M, in the ends of which a hole is drilled for the reception of a
wire N, N, which also traverses the length of the frame. This wire is on a
level with the bottom part of the bobbins or spools, and when it is brought into
action by means of the gearing hereafter to be described, or by hand, the wire
strikes against the bobbins, and throws them all off simultaneously into a
pocket or receiver O placed in front and along the length of the machine.
This pocket or receiver, when not required for use, falls down in front of the
machine, as represented by the dotted lines in Figure 2; but when it is desired
to doff the bobbins, the pocket is raised up either by hand or by the gearing at
the end of the machine. The spindles P, P, passing through the flyer tubes H,
are so connected to the lifting bar K, and the traverse of this bar is such, that
when it is desired to throw off the bobbins the spindles are all lowered, to
admit of their being easily doffed when the doffing wire is brought up in con-
tact with the lower part of the bobbius, and throws them off the spindles.

page_text: In machines constructed in accordance with our Invention, and where the
flyers are inverted, the traverse or lowering of the spindles P,P,must be such
as to withdraw them from within the bobbins, tubes, or spools. This we
accomplish by working the copping or winding shaft K beyond the ordinary
traverse. But when it.is.desired.to.adapt.this.doffing arrangement_to.ordi-
nary spinning machines which have the flyers fixed on the ends of the spindles
and above the bobbins, the lifting plates or rails carrying the bobbins mustbe
raised sufficiently to admit of the bobbins being thrown off. Whenthebobbins
have been thus thrown off, it is necessary to place upon the spindles fresh or
empty bobbins. To accomplish this object we place behind the bobbins a
longitudinal shape or spindle Q, carrying a number of fingers R,R,one finger
to each spindle. In the ends of each finger we insert a projecting pin d and
spring e, upon which the empty bobbins are placed, and there retained until
liberated by the "putting-on" action of the apparatus. When it is desired
to place fresh bobbins upon the spindles, the shaft Q is partially turned either.
by hand or by being placed in connection with the moving parts of the
machine, to bring the bobbins down upon the lifting plates upon the spindles.
The spindles P, P, are then caused to rise and press the bobbins against the
front of the hent springs f, at the back of the fingers, which act upon the.
heads of the projecting pins d,and so serve to draw them through holes in
the fingers, whereby the springs e, which hitherto held the bobbins, become
compressed, and when the shaft Q is restored to its first position the empty
bobbins are all left upon their respective spindles. The thread is thenattached
to the bobbins, spools, or tubes, by inserting the end of it. between a small
steel spring g, and the bobbin as shewn in Figure 2a, and the machine-is
ready to be put in motion for winding on the thread. The shaft Q has a
slight-lateral motion, so that when the bobbins are placed by the fingers
upon the spindles, and the shaft restored to its first position, this shaft is
moved slightly to the right or left, which motion brings the fingers between
the bobbins; and thus sufficient space is left for placing fresh or empty
bobbins on the projecting pins during the working of the machine; but
when it is required to place the bobbins upon the spindles, the shaft is
again shifted so as to bring the fingers exactly in a line with the spindles P.,P.
The method which we adopt for connecting these various parts to thedriving
gearing of the machine is as follows:-S is an upright spindle;turning in a
step in the bracket St,and supported in its position by the bracket S2. T is-
a bevil wheel upon the end of the shaft Q, carrying the fingers R.This bevil
wheel gears into a similar bevil wheel on the spindle S when working the
shaft. U is a cam, also upon the spindle S, which bears upon the end of the
.

page_text: shaft Q,and serves to give to this shaft the requisite lateral notionforbringing
the fingers between the bobbins, and also for throwing the bevil wheel Tout
of gear with the wheel on the spindle S. V is a handle upon the end of the
spindle L, for the purpose of bringing the doffing wire into action against
the bobbins when it is desired to throw them off. W is a bevil wheel on the
shaft carrying the spur pinions, for giving the rising and falling motion to
the spindles P, P. This bevil wheel gears into and is driven by a similar
wheel W on the spindle S. W is a cam on the spindle S, for throwing the
bevil wheel W out of gear when not required to use the doffing apparatus.
X is a cam upon the bottom part of the spindle, which comes against the stop
pin Y,and thus-determines the position of the working parts, to cause them
all exactly to correspond and act in their order and time. Z is a hand wheel,
for giving motion to the spindle S. Z4,Z2, are springs placed at the back of
the fingers M, M, and the shaft Q, and are for the purpose of restoring these
parts to their positions when not in action.
Our Invention consists, secondly, in an elastic flyer, that is to say, we so
construct the flyerthat the tops thereof are formed of an elastic substance, so
that the legs, which we prefer to make tubular, approach each other as repre-
sented in Figure 3,and bear upon the thread as it is laid upon the bobbins,
but at the same time, as the diameter of the bobbins increases as the thread is
laid, these legs are forced further apart, as shewn by the dotted lines. A is
the spindle; B, the bobbins; C, the flyer; and D, the roving yarn. By this
means the thread is laid tighter upon the bobbins.
Our Invention also relates to an improved flyer top, and consists in giving
an extra twist or-bend to the flyer legs, between the ordinary-bend and the
top of the flyer, also in so connecting this flyer by making the top of the
spindle slightly conical,and forming the whole through the flyer of a corre-
sponding shape, so that it admits of the flyer being readily removed from off
-the spindle, as shewn in Figure 4.
And having now described the nature of our said Invention, and in what
mauner the same is to be performed, we declare, that although we have
explained and represented in the Drawings hereunto annexed one particular
method of carrying the first part of our Invention into effect, we do not.
confine ourselves to this particular arrangement, as other methods may be
adopted, and found equally effective in practice; butthat what we claim is,
First, the doffing or removing of the full bobbins, tubes, or spools, in
machines for preparing, spinning, doubling, twisting, and winding fibrous sub-
stances, from off their respective spindles,and replacing the same by empty
bobbins, tubes, or spools, by mechanical means. We also claim the particular

page_text: arrangements of machinery for doffing the full bobbins and replacing them by
empty bobbins, herein-before described.
Second, we claim the placing in front of machines for preparing,spinning,
doubling, twisting, and winding fibrous substances, of a pocket or receiver, to
receive-the-bobbins, spools,-or-tubes-when-thrown-off.or.doffed._
Third, we claim forming either the legs or tops of flyers of an elastic
substance, so.that the legs, which may be tubular or otherwise, approach each
other,and bear upon the thread in the manner and for the purpose herein-
before described, and represented in the Drawings hereunto annexed.
Fourth, we claim the improved construction of flyer top represented in
Figure 4 of the Drawings hereunto annexed, and herein-before described.
And, fifth, we claim the application and use of a spring attached to bobbins,
tubes, spools, or other equivalents, in order to secure the thread to the
bobbins, tubes, or spools, as herein-before described, and represented in
Figure 2 of the Drawings hereunto annexed.
In witness whereof, we, the said Robert Ashworth and Samuel Stott,
have hereunto set our hands and seals, this Twenty-seventh day of
November, One thousand eight hundred and fifty-five.
