Sealed the 20th October 1871, and dated the 25th April 1871.
PROVISIONAL SPECIFICATION left by the said Caleb Norris and
Jolin Seed at the Office of the Commissioners of Patents, with their
Petition, on the 25th April 1871.
We, CALEB NORRIS, of Farington, near Preston, in the County of
Lancaster, Overlooker of Mules, and JoшN SEED, of the same Place,
Foreman Mechanic, 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:-
Our Invention relates to that part of the mule called the winding-on
motion, and the object thereof is to regulate the speed of the spindles

page_text: during the formation of that part of the cop called "nosing." For this
purpose we attach a lever (curved by-preference) by means of a joint to
the nut of the ordinary radial arm, and to the end of this lever the
winding-on chain is attached. Bearing against the said lever is an arm
which is jointed to a bracket fixed to the "radial arm," and its position
may be altered by a set screw or by similar means, As the nut is moved
upward on the "regulating screw it carries with it the aforesaid lever,
which by bearing against the above-mentioned arm at different distances
from the centre of of motion is caused to turn upon its said centre and
take up sufficient chain for varying the speed of the spindles.

SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Caleb Norris and John Seed in the Great Seal
Patent Office on the 25th October 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, wc, CALEB
NORRIS, of Farington, near Preston, in the County of Lancaster, Over-
looker of Mules, and JOHN SEED, of the same Place, Foreman Mechanic,
send greeting.

WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fifth day of April, in the year
of our Lord One thousand eight hundred and seventy-one, in the
thirty-fourth year of Her reign, did, for Herself, Her heirs and succes-
sors, give and grant unto us, the said Caleb, Norris and John Sced,
Her special license that we, the said Caleb Norris and John Seed, our
executors, administrators, and assigns, or such others as we, the said
Caleb. Norris and John Seed, our 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 law-
fully 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 we, the said Caleb Norris and John Seed, by an instrument
in writing under our hands and seals (or under the hand and seal of

page_text: 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 Scal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YẺ, that we, the said Caleb Norris and John Seed, 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 self-acting mules called the
winding-on motion, and the object thereof is to regulate the speed
of the spindles during that part of the formation of the cop called
"nosing."
In the accompanying Drawing our Invention is shewn at Fig. 1.
in two positions of the winding-on, the full lines representing the parts
as they are just before the winding on commences, the carriage being
run out, and the dotted lines reprosent the positions the parts assume
when the said winding is taking place upon the nose of the cop, and
at which time our Invention comes into operation. The period at which
our Invention begins to act may be varied, as will hereafter be seen,
but we will suppose it to commence when the yarn is being wound
about one-third of the way up the conical part of the cop, that being.
the position where other nosing arrangements usually commence. At 1
is the usual quadrant, and at 2 the radial arm turning upon its centre 3.
At the upper end of this radial arm is a bracket 4, which carries a
nut o mounted so as to be capable of swivelling upon a centre. In
this nut is a screw 6, the lower end of which is connected by a ball
joint to a lever 7, jointed at S to the bracket 4, and therefore owing to
this ball joint the screw 6 may be turned and moved upward or down-
ward so as to carry with it the lever 7, the nut 5 admitting of this motion
by swivelling upon its centre. At 9 is a part projecting from the usual
nut of the regulating screw, and to it is jointed an arm 10, to the other
end of which is fastened the winding-on chain 11, passing as usual to
the drum 12.
The operation is as follows:-On the commencement of winding-on
the radial arm 2, as is well understood, turns over in the direction of the

page_text: arrow, and the operation proceeds as usual until the motion of the spindles
is required to be accelerated in order to wind the yarn firmly on the nose
of the cop. When this point has been arrived at, the turning over of the
radial arm 2 will have brought the arm 10 into contact with the lever 7,
as shewn by the dotted lines, and thus a certain amount of leverage is
brought to bear against the said arm, which leverage will increase as the
radial arm 2 continues to turn downward, the lever 7 approaching
nearer to the centre of motion 9, and thus a certain amount of chain
will be taken up by the turning of the arm 10 upon its centre, and
the speed of the spindles will be proportionately increased. The time
at which the operation of our Invention shall come into action may
be regulated by turning the screw 6 upward or downward and so
adjusting the lever 7 nearer to or further from the arm 10 and the
spinner may therefore alter the action of the apparatus as he finds it
necessary. Fig. 2 represents a modification of our Invention, the
difference being that in this instance the action effected by the screw 6
is rendered elastic by the use of a weight and stop pin. The parts
which agree with those of the previously described arrangement are
marked with the same letters of reference, but to the lever 7 is connected
a rod 13 which carries at its upper end a weight 14, and is provided
with an adjustable stop 15 which rests upon the bracket 4. When
the radial arm 2 turns over as above mentioned it takes the weight 14
with it, but it is prevented from falling over beyond a certain point
by the stop 15, as seen by the dotted lines, which as before represent
the positions of the parts when our Invention first comes into operation,
the lever 7 being just in contact with the arm 10. The winding-on
proceeding, and the radial arm turning further over the lever 7 as before,
exerts an increased leverage and commences to take up the chain, but
at the same time the stop 15 becomes free of the bracket 4, and the
lever 7 is kept against the arm 10, not as before by a rigid screw, but
by a yielding adjustment in the weight 14 which is so adjusted upon
its rod 13 as to exert a sufficient pressure for winding on the yarn tight.
The time at which our Invention shall come into operation is regulated
by shifting the stop 15 on the rod 13, and so moving the lever 7 upward
or downward.
Having thus described and ascertained the nature of our said Inven-
tion and the manner in which the same is to be performed, we desire
it to be understood that we claim as secured to us under the above

page_text: in part recited Letters Patent, and for the purpose above set forth, the
usc of the lever 7 and arm 10 regulated in their action by a screw
weight or equivalent apparatus.
In witness whercof, I, the said John Seed, have hereunto set my
hand and seal, this Twenty-fourth day of October, in the year
of our Lord One thousand eight hundred and seventy-onc.
