I, JOHN DODD, of Oldham, in the County of Lancaster, Mechanical
Engineer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN MULES FOR SPINNING AND DOUBLING COTTON AND OTHER FIBROUS
MATERIALS," to be as follows:-
My Invention relates,-
Firstly. To a method of governing the motion of the counterfaller
during the rise of the front or winding faller at the termination of the
inward run, and preparatory to making another stretch. For this
purpose I apply projections to the two faller shafts, and to which each
"

page_text: end of a chain is connected. Within the loop formed by this chain is a
roller carried by a lever capable of turning upon a centre on the carriage.
During the going in and coming out of the carriage the apparatus above
described is inoperative, the faller being allowed to move as required, but
when the carriage is arriving at the termination of its inward run the
aforesaid lever is no longer capable of turning upon its centre, and then
when the projection of the front faller pulls up the chain the other end
thereof will cause the counterfaller to be pulled downward. For the
purpose of preventing the said lever from turning upon its centre I
furnish it with a bowl which runs under an incline fixed to any stationary 1
part, and which may be made adjustable.
Secondly. My Invention relates to an improvement upon that arrange-
ment for taking up the slack of the breaking-off chain, for which Letters
Patent were granted to me dated 21st August 1872, No. 2482. I still
propose to use the bell-crank lever 28, 28, and incline 36, but instead of 1
using the backing-off chain as the medium for depressing the faller I
employ a jointed rod or other separate part, one end of which is attached
to the aforesaid lever, and the other to a finger extending from the front
faller.
Thirdly. My Invention relates to the third part of my former Patent 2
aforesaid, and consists in a method of giving motion to or governing the
motion when required of the volute wheels described by me in tho
Specification of the said Patent, or to equivalent apparatus. For this
purpose I employ a pair of friction cones, the one fast and the other
loose upon the axis of the tin roller. To the loose and sliding part is 2
connected a pinion, which by means of other gearing communicates
with the volute wheels as before, but upon the carrier is a tappet, which
by bearing against a flange of the aforesaid pinion keeps the sliding cone
out of gear when the faller is lifted and the carriage is coming out, the
said cone having a constant tendency to pass into gear by means of a 3
weighted lever. To this lever is connected a rod which carries a stud
situate within a slot formed in another rod which is connected to the
locking lever." One side of this slot at times prevents the friction
cones from passing into gear, but when that operation is to take place
the end of the said slot will have brought a recess opposite to the stud, 3
and thus the rod which carries it will be allowed to slide. When the
carriage is out at full stretch the friction cones are kept out of gear by
the lever arriving against a fixed incline. This part of my Invention
"

page_text: may be used in conjunction with other faller lifting apparatus used in
place of the volute wheels above referred to.
The fourth part of my Invention relates to the regulating screw and
nut of the quadrant when the said screw is of variable pitch. The nut
I make as a collar, which would of itself be capable of sliding upon the`
variable portion of the screw, but it carries a pin or swivel which
projects into the thread of the said screw, and so far this is the known
arrangement. This collar however I tap to take into that part of the
screw which is of uniform pitch, and which I accordingly make of
increased diameter. By these means a perfect nut is obtained when it
has the greatest amount of work to accomplish.
The fifth part of my Invention relates to the winding faller, and is
intended to govern its motion at the termination of the inward run, so
that the copping rail shall retain the faller in position until the friction
apparatus referred to under the third part of my Invention has control
over it, for which purpose I cause a catch to be situate under a projec-
tion extending from the winding sector while the locking lever rests
upon the usual bowl, and which catch subsequently detains the winding
sector until the friction apparatus is in full action. I propose to mount
the aforesaid catch on a lever capable of turning loosely upon the
winding faller shaft, and to press it towards the aforesaid projection by
means of a spring. The said lever is provided with a connecting rod,
the lower end of which is mounted on the stud of the locking bowl.
Upon this rod is a stop for regulating the position of the catch.

twenty-eighth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said John Dodd, Her special
license that I, the said John Dodd, my executors, administrators,
and assigns, or such others as I, the said John Dodd, my executors,
administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter 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 " IMPROVEMENTS
IN MULES FOR SPINNING AND DOUBLING COTTON AND OTHER FIBROUS MATERIALS,"
upon the condition, amongst others, that I, the said John Dodd, by
an instrument in writing under my hand and seal, 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 Scal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW, KNOW YE, that I, the said John Dodd, do hereby declare
the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement and accompanying Drawings, that is to say:
My Invention relates,―
Firstly. To a method of governing the motion of the counterfaller
'during the rise of the front faller at the termination of the inward rim
and preparatory to making another stretch. The arrangement I adopt
for this purpose is shewn at Fig. 1. At a is the counterfaller to which
is attached a projecting arm 6, and fixed to the front faller c is another
arm d; each of these arms carries a stud c, f, to which are attached
the two ends of a chain g hanging downward and within the loop thus
formed is a bowl carried by a lever i which is capable of turning
upon a centre supported by the square of the carriage. Fixed to the
stationary frame is a bracket m formed with an inclinen on one of its
ends, and beneath this bracket (at a time hereafter to be described) there
'arrives a bowl _carried by the aforesaid lever i which is consequently
under those circumstances prevented from turning upward on its centre,
but at other times it is free to do so."
It will have been seen from the above description that with the
• exception of the bracket m the several parts above referred to move
bodily together with the carriage, and the operation is as follows:-

page_text: During the inward run or until just before that motion is completed, and
during the outward. run, the bowl o is away from the bracket m so that
the lever i is free to turn upon its centre k and the fallers are at liberty
to move as may be required, the bowl hanging in the loop formed by
the chain g. The weight of the lever i however being checked by the
set screw p just before the completion of the inward run the bowl o
arrives against the incline n and passes under the bracket m so that the.
said lever is no longer capable of turning upward, and the bowl o
becomes practically stationary. The front faller c now beginning to
rise to coil the yarn upon the spindle will by means of the arm & draw
upward the chain g over the bowl h, and the other end of the said chain
being consequently drawn downward will pull down the arm and
depress the counterfaller. The arm & may be made in a curved form
with the chain passing over it in order to make the action variable.
The second part of my Invention relates to an improvement upon
that arrangement for taking up the slack of the backing-off chain,
for which Letters Patent were granted to me, dated Twenty-first
August, One thousand eight hundred and seventy-two, No. 2482.
I still propose to use the bell-crank lever 28, 28*, and incline 36,
described in the Specification of the said Patent, and indicated by those
numbers of reference, but instead of using the backing-off chain as the
medium for depressing the faller I employ a jointed rod or other separate
part, one end of which is connected to the aforesaid lever and the other
to a finger extending from the front faller. The arrangement I adopt
for this purpose is shewn at Fig. 2, which is the same as that repre-
sented at Fig. 3 of my former Specification aforesaid, with the exception
of an added part which constitutes my present Invertion; and I shall
use the same numbers of reference for the same parts where they occur,
and letters for the parts now added. At 20 is the backing-off chain
which after passing over a guide pulley 22 is connected to the lever 21
of the front faller. At 28, 28*, is the bell-crank lever provided with the
bowl 29, which when the outward run is nearly completed runs up the
incline 36 to take up the slack of the chain 20 through the agency of
the chain 27, the action of all of which parts is fully explained under
5 my former Patent above referred to; and for the simple purpose of
taking up the slack of the backing-off chain the arrangement is
satisfactory. When however it is desired in addition to that to pull
down the faller by means of the said chain I find that the pressure on

page_text: "
the "
snail causes the tin roller shaft and the said "snail" to be heated,
and it is to obviate this result that my present Invention is designed.
Upon the lever 28 I form a second slot a, to which is connected one
end of a rod b, its other end being connected by means of a pin c situate
in a slot to the arm 21 of the faller. When the bowl 29 arrives against
the incline 36 the first action of the lever 28, 28*, by turning upon its
centre 30 is to take up the slack of the backing off chain 20, as described
under my former Patent, but at the same time the turning of the said
lever 28, 28*, will draw downward the rod 6 and with it the lever 21,
and cause the faller lever to be depressed; the result of course will
be that a certain length of the chain 20 is given off by the arm 21
which would again slacken the said chain 20, but at the same time that
this is being done the chain 27 continues taking up the slack; and
these motions are so arranged that the chain 20 is practically ready to
start, but sufficiently loose to take the strain off the tin roller shaft.
The rod is provided with a double joint f, g, to enable its end to move
with the arm 21, and its position on the lever 28 may be adjusted by a
set screw.
Instead of the rod a chain or similar connexion may be
established between the lever 28 and arm 21, the essential character of
this part of my Invention being the employment of the said lever for
pulling down the faller independently of the backing-off chain.
The third part of my Invention relates to the third part of my former
Patent aforesaid, and consists in a method of giving motion to or
governing the motion when required of the volute wheels, described by
me in the Specification of the said Patent or to equivalent apparatus,
and is shewn at Figs. 3, 3*, and 4, this, my present Invention, being
intended to take the place of the click, plate, and spring, described in
the Specification of my former Patent. The Drawing is precisely the
same as that of my said former Patent in general character, and the
same numbers of reference are used to indicate the same parts, thoso
which are necessary for my present Invention being marked with
letters. At 41 and 42 are the volute wheels connected by gearing 44,
45, to the pinion 46. At 47 is the tin roller shaft on which is fixed a
hollow friction cone a, and within which is the other cone 6 adapted
so as to slide loosely on the tin roller shaft 47, and is fast to the
pinion 46. This pinion is made long enough in the tooth to allow the
friction to be slided in and out of gear with the other friction, and
also to keep in gear with the wheel 45. The pinion 46 is formed with a

page_text: flange c,
and upon the rim of the wheel 45 is an incline d capable of
acting on the said flange of the pinion 46. When the faller is lifted and
the carriage is coming out the incline d is situate against the flange c,
and so prevents the two friction cones being put into gear.
The boss
The bracket g

of the sliding friction is provided with a groove for the reception of a
fork 55 extending from a lever 58, which is weighted or drawn by a spring
so as to impart a constant tendency to the sliding friction 6 to pass.
into gear.
To the upper part of the lever 58 is connected by a stud, a
rode, the other end of which carries a stud f, and this rod e is mounted
so as to slide in a bracket g. The parts just alluded to are shewn broken
off in Fig. 3, in order to bring them nearer to the other parts, as seen
at Fig. 3*, in which they are also in a different position.
also supports another sliding rod h which is connected to
lever 91 in connection with the locking lever 101. As the faller is
unlocked and locked the rod h slides in and out across the end of the
other rod e, and its end is formed with two steps i, k, the stud f at times
resting upon the former, and at other times passing into the space
formed by the latter, but not touching it. When the carriage is out at
full stretch the friction cones a, b, are kept out of gear by the lower
end of the lever 58 arriving into contact with an incline 70 in order to
prevent the said cones from going into gear during the backing off.
The object of this part of my Invention is to lock the tin roller and
winding faller together by means of the volute wheels and gearing or
by any similar contrivance in such a manner that if one moves the
other must move, and so act perfectly together, but of course so
soon as the faller is lifted this positive connexion must instantly be
severed.
The Drawing, Figs. 3 and 4, shew the parts in the positions they
assume when the carriage is out, but I will first describe the operation
at the termination of the inward run. When the lever 101 is, almost
liberated from the bowl 102, and about to be disengaged from it as is
well understood, the end of the rod will be just liberating the stud fon
the rod c, as shewn at Fig. 3*, which stud by passing into to the space k
by means of the weighted end of the lever 58 will allow the fork 55 to
place the friction cones a, b, into gear, and at once couple the faller and
tin roller together, and so enable the yarn to be wound perfectly on the
spindles. Just before the faller wire has arrived at the termination of
its lifting motion the incline d on the carrier wheel 45 will have arrived

page_text: As
in contact with the flange c on the pinion 46; and will have forced the.
sliding friction cone out of gear, and the connection then ceases.
soon as the outward run is completed the lever 58 arrives in contact
with the incline 70, and when on backing off the incline d leaves the
flange c of the pinion 46 the friction cones are prevented from gearing.
As soon as the fallers are locked the slide rod e is secured by the step i,
and so keeps the sliding cone out of gear until again liberated by the
unlocking of the faller.
The fourth part of my Invention according to my provisional Speci-
fication related to the regulating screw and nut of the quadrant when
the said screw is of variable pitch. The nut I proposed to make as a
collar, which of itself would be capable of sliding on the variable part of
the screw; but it carried a pin or swivel which projected into the thread
of the screw, and so far this was the ordinary arrangement. This collar
however I tapped to take into the part of the screw which was of
uniform pitch, and which I accordingly made of increased diameter.
Since the filing of my said provisional Specification I have had doubts
as to the novelty of this arrangement, and therefore make no claim
thereto:
.
The fourth part of my Invention relates to the winding faller, and is
intended to govern its motion at the termination of the inward run, so
that the copping-rail shall retain the faller in position until the friction
apparatus referred to under the third part of my Invention has control
over it. This part of my. Invention is shewn at Figs. 5, 6, and 7, of which
Fig. 5 shows the parts in the positions they occupy when the spinning
operation is going on during the outward run of the carriage; Fig. 6,
the position of the said parts at the instant they are to come into
action; and Fig. 7, a front elevation of the parts. The black lines
which represent the locking lever indicate that the action has not
begun, and the blue lines shew the said lever when it is unlocked and
at the moment when the action is to begin, that is to say, at a time
when a preparation has been made for the operation of those parts
constituting my Invention. At a, b, are the two faller shafts, and at c
the usual locking lever, which, as shewn in Fig. 7, is resting upon the
usual bowl for supporting it when the faller is locked. Upon the
winding faller shaft is mounted loosely a lever d, shewn by red lines,
and to this lever is connected by a stud a bar e, the lower end of which

In witness whereof, I, the said John Dodd, have hereunto set my
hand and seal, this Twenty-third day of February, in the year
of our Lord One thousand eight hundred and seventy-five.
