IMPROVEMENTS IN MULES FOR Sonoma AND DOUBLING
Year: 1872

page_text: LETTERS PATENT to John Dodd, of Oldham, in the County of
Lancaster, Mechanical Engineer, and Robert Buckley, of Oldham,
aforesaid, Spinner, for the Invention of "IMPROVEMENTS IN MULES FOR
Sonoma AND DOUBLING"
PROVISIONAL SPECIFICATION left by the said John Dodd and Robert
Buckley at the Office of the Commissioners of Patents, with their
Petition, on the 27th November 1872.
We, JOHN DODD, of Oldham, in the County of Lancaster, Mechanical
Engineer, and ROBERT BUCKLEY, of Oldham, aforesaid, Spinner, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MULES POR SPINNING AND DOUBLING," to be as follows:-
•
Our Invention relates to that part of mules which is used for regu-
lating the position of the nut or the screw of the winding-on motion,
and which is commonly called the governor motion, the object being to
regulate the motion of the counter faller during the building up of the cop
bottom. To effect this we cause a projecting part or parts on the wind-

page_text: ing-on faller to arrive in contact with a lever, to which one end of the
ordinary chain is attached, the other end, after passing round a roller on
the "engaging and disengaging lever," is attached to the counter faller
as usual, but the said projecting part or the said lever, or both of them
are formed with an incline which regulates the giving-off and taking-up
of the chain. This may be illustrated as follows:-Upon the winding-on
faller shaft we place a projecting part having an incline thereon, which
acts against a lever drawn towards it by a spring, or equivalent appa-
ratus, one end of the ordinary chain being attached to the said lever
and the other, as usual, to the winding-on faller. The said lever may be
acted on by the incline so as to shorten the chain from maximum to
minimum, or vice versa, and may itself be furnished with an incline, and
we propose to make the aforesaid projecting part in two or more pieces
capable of adjustment.
We also propose to furnish the above-mentioned lever, or part
connected therewith, with a segmental ratchet or similar apparatus,
into which a click projects to hold it in a fixed position, but which is
released by a tappet when the lever has to give off or take up chain...
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Dodd and Robert Buckley in the Great Seal
Patent Office on the 27th May 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
DODD, of Oldham, in the County of Lancaster, Mechanical Engineer,

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," upon the condition, amongst others, that we,
the said John Dodd and Robert Buckley, 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 In-
vention, 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 immediately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said John Dodd and Robert Buckley,.
do hereby declare the nature of our 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 :—
Our Invention relates to that part of mules which is used for
regulating the position of the nut on the screw of the winding-on
motion, and which is commonly called the governor motion, the object
being to regulate the motion of the counter faller during the building up
of the cop. In the accompanying Drawings Fig. 1 represents certain.
parts of a mule in section with our improvement adapted, and Fig. 2 is
a partial end view of the same. The winding on faller shaft is at 1, and
that of the counter faller at 2; at 3 is the usual band, by means of which
motion is imparted to the quadrant nut; at 4 is the star plate; and at 5
the pin which takes into it, carried by a lever 6 in the ordinary manner.
Upon the faller shaft 1 is an arm 7, to which is attached a series of pins
8, 9, 10, provided with slots and bolts, by means of which they may be
adjusted inward or outward, and their outward parts constitute a surface
capable of acting as an incline or cam, the exact form of which,
however, may be varied by the aforesaid adjustments, and at 11 is
another similar pin, the function of which is separate from that of the
others, as will hereafter be described. At 12, 12 is a lever situate at
front of the pins 8, 9, 10, capable of turning upon a centre 13 carried by
the frame 14 of the mule and furnished with an adjustable hook 15, to
which is attached one end of the governor chain 16, which is made fast
by a set screw to a scroll 17 mounted upon a shaft 18, and from thence
proceeds over a roller 19 carried by the lever 6, after which it is attached
to an arm 17* on the counter faller shaft 2.

page_text: The operation is as follows:-The positions of the parts being those
they assume, when the winding-on is taking place, and the faller shaft
is turned in the direction of the arrow, thereby bringing by means of the
arm 7 one or other of the pins 8, 9, 10 into a position to act as a stop for
the lever 12, and allowing it to be drawn a certain distance forward by
the weight of the lever 6. The effect of this is to allow the chain 16 to
drop the said lever 6 so far as it is affected by that end of the chain.
The other end of the chain 1, which is attached to the counter faller
arm, acts in the usual manner, the said arm being pulled down when
the yarn is being wound on the cop too quickly, and affording a length
of chain for allowing the lover 6 to drop and lock the star plate, and the
usual action upon the nut of the quadrant screw then takes place.
When, according to the ordinary operation of backing off, the faller
descends, the arm 7 and its pins 8, 9, 10, move upward preparatory for
another operation like that above described, but with this modification:
-At the commencement of forming a set of cops the faller shaft moves
the greatest distance in the direction of the dotted arrow, and conse-
quently the arm 7 and its pins 8, 9, 10, the greatest distance in the
contrary direction, thus allowing the lever 12 to move the greatest
distance forward, and correspondingly lower the chain 16; but as the
building of the cop advances the motion of the faller becomes less, and
consequently the lever 12 is gradually prevented from moving so far
forward as it had previously so moved.
For the correct working of the counter faller it is necessary that as the
cop bottom is built up it should descend lower before it allows the lever 6
to act on the star plate; and to accomplish this the chain is governed in
the manner above described, for as one end of the said chain is taken up
a corresponding lowering of the position of the arm 17* will be necessary
before the lever 6 can act on the star plate; the amount of such take up
is regulated by the form of the lever 12* and pins 8, 9, 10. The scroll 17
is employed to carry the chain for the purpose of increasing the quantity
of motion given thereto. The pin 11 is specially employed to make sure
that the lever 12* is moved back sufficiently to secure the disengagement
of the lever 6 from the star plate, when the counter faller is depressed
during the operation of spinning. Upon the lever 12 is a trigger 18*,
capable of turning upon a centre in the direction of the arrow, but pre-
vented from turning in the other direction by means of a stop. Against
this trigger the end 7* of the lever 7 arrives when backing off and

page_text: during the going down of the faller whilst winding down, but the upward
motion of the lever 7* cannot turn the said trigger on its centre, and
therefore pushes it and the lever 12 bodily backwards, but when the
motion enables the end 7* to pass over the trigger the lever 12 then falls
against the pins 8, 9, 10, as before described. When the movement of
the lever 7 is reversed the point 7* turns the trigger on its centre, which
allows the point 7* passing without disturbing the position of the lever 12.
The object of using this trigger 18 is to prevent the disengaging lever
acting on the star plate during the time the yarn is being wound from
the nose of the cop to the base of the cone, which in some mules it has a
tendency to do. When the cop bottom is about one-third or one-half
finished the end 7* of the lever ceases to pass over the end of the trigger,
and the result is that the disengaging lever cannot act on the star plate
until the point 7* during the rise of the winding faller has got clear of
the trigger, and the face of the lever 12 is pressing against the pins 8, 9,
10, which then determines accurately the working position at which the
arm 17* shall be able to engage the lever 6*.
lever 12 to arrive in
suit each particular
The trigger 18 can be set so as to allow the
contact with the pins 8, 9, 10, sooner or later, to
mule, but this trigger arrangement may not in some mules be required.
Figs. 3 and 4 represent a modification in the arrangement of our
Invention. At 19, 19*, is a double lever drawn at one end 19* against
a fixed stop 21 by means of a spring 22. The other end 19 is provided
with a hook, to which is attached the ordinary chain 23, the upper end
of which is attached to the counter faller arm 24. The lever 19, 19*, is
provided with a ratchet sector 25, and carries an adjustable incline 26.
The faller shaft has an arm 20, 20*, a set screw 29 on the end 20* thereof
being in the same plane with an arm extending from the catch 27, which
is capable of turning upon a fixed centre 28, according to the positions
of the parts shewn the spinning operation is going on, the faller being at
its highest point. When it descends the set screw 29, by the turning of
the lever 20, 20* leaves the catch 27, which then falls on to the teeth of
the sector 25, and a further depression of the faller brings the part 20* to
bear against the incline 26, thereby depressing the lever 19, and by
causing it to turn upon its centre lowers that part of the chain which is
attached to the said lever, and the catch 27 being in gear with the
teeth 25, the parts are held in that position when the lever 20 leaves the
incline 26, and so on for each stretch; but when by the rising of the

page_text: faller the set screw 29 again arrives in contact with the catch 27 it is
removed from the teeth of the sector, and the spring 22 restores the
lever 19, 19*, to its normal position. As the faller decreases in the
extent of its motion, according to the usual operation the lever 20 passes
for a smaller distance along the incline 26, and consequently passes a
fewer number of teeth under the catch 27, thereby effecting the variable
operation before described.
Fig. 5 represents another modification of our Invention. In this
instance an incline 30 is fixed upon the faller shaft, resting upon which
is a roller 31, carried by a lever 32, turning on a fixed centre 33, the
other end of the said lever carrying the chain 34, also attached as before
to the counter faller arm 35.
The operation of this apparatus is the same as those already described,
the incline 30 permitting the roller 31 and consequently chain 34 to fall
at a. differential rate according to the extent of the faller's motion and
shape of the incline 30. At 36 is a dead run for the roller to rest upon.
The incline 30 differs only from that formed by the pins 8, 9, 10, Fig. 1,
inasmuch as it made into a continuous surface.
Having thus described and ascertained the nature of my said Invention,
and the manner in which the same is to be performed, I desire it to be
understood that we claim, as secured to us under the above in part
recited Letters Patent, and for the purpose above set forth, the adaptation
of a projecting part or parts to the winding faller shaft or part moving
therewith, for the purpose of causing such part or parts to arrive in
contact with a lever or similar apparatus, to which one end of the
ordinary governor chain is connected.
In witness whereof, I, the said John Dodd, have hereunto set my
hand and seal, this Twenty-sixth day of May, in the year of our
Lord One thousand eight hundred and seventy-three.
