Year: 1875

page_text: LETTERS PATENT to James Cryer, of Dukinfield, in the County of
Chester, Machine Maker, and Samuel Morris, of Mossley, in the
County of York, Mill Manager, for the Invention of "CERTAIN
IMPROVEMENTS IN SELF-ACTING MULES FOR SPINNING AND DOUBLING.
PROVISIONAL SPECIFICATION left by the said James Cryer and
Samuel Morris at the Office of the Commissioners of Patents,
with their Petition, on the 29th December 1875.
We, JAMES CRYER, of Dukinfield, in the County of Chester, Machine
Maker, and SAMUEL MORRIS, of Mossley, in the County of York, Mill
Manager, do hereby declare the nature of the said Invention for
"CERTAIN IMPROVEMENTS IN SELF-ACTING MULES FOR SPINNING AND DOUBLING,"
to be as follows:-
Our Invention consists in an improved self-acting apparatus for
regulating the tension of the yarn during the building of the bottom of
the cop and until it arrives at its full diameter.

page_text: Our improved apparatus consists of a worm fixed to the ordinary
strapping or winding band pulley mounted on the stud of the radial
or quadrant; this worm gears into a wheel on a short shaft, to the lower
end of which is fixed another worm gearing into a wheel on a hori-
zontal square or grooved round shaft passing under the carriage and to
the required length of the stretch. On this horizontal shaft is mounted
a lever, which is moved to and fro by the carriage; to the end of this
lever is connected the lower end of the regulating chain, which passes
over the counterfaller shaft over a pulley on an arm fixed to the counter-
faller shaft round the pulley on the ordinary strapping or winding
motion lever, and the other end of the chain is connected to an arm on
the copping faller shaft, which is placed in such a position that when the
faller locks it has given off all its chain; when the faller begins to wind
it draws the chain, which draws the strapping lever out of motion until
the winding has got past the lowest point on the cop, consequently
driving the regulating motion to the latter end of the winding on.
the regulating screw on the quadrant or radial arm is turned round by
the ordinary strapping or winding band to wind the nut upwards-the-
horizontal shaft is moved slowly partly round by the worms and wheels
above described, and in so doing the lever on the horizontal shaft is
drawn downwards to tighten the regulating chain, thereby-keeping the
yarn at the proper tension during the winding on.
As
Instead of the worms and wheels above described the horizontal shaft
can be acted upon by bevel pinions and a screw acting on a lever on
the horizontal shaft, the driving bevel pinion being fixed on the
strapping band pulley above referred to. Or the regulating chain can be
tightened by a worm fixed to the ordinary star wheel or break pulley in
the carriage square, this worm gearing into a wheel on a shaft, on
which is fixed another worm gearing into a wheel attached to a lever,
to which the end of the regulating chain above described is connected.
Or a bevel pinion may be fixed to the star wheel or break pulley above
referred to, and this bevel wheel may give motion to a screw connected,
as before described to a lever connected to the regulating chain. The
above details can be varied.

filed by the said James Cryer and Samuel Morris in the Great
Seal Patent Office on the 29th June 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JAMES
CRYER, of Dukinfield, in the County of Chester, Machine Maker, and
SAMUEL MORRIS, of Mossley, in the County of York, Mill Manager,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-ninth day of December, in
the year of our Lord One thousand eight hundred and seventy-five,
in the thirty-ninth year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto us, the said James Cryer and Samuel
Morris, Her special licence that we, the said James Cryer and Samuel
Morris, our executors, administrators, and assigns, or such others as
we, the said James Cryer and Samuel Morris, our executors, admini-
strators, 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 "CERTAIN IMPROVEMENTS IN
SELF-ACTING MULES FOR SPINNING AND DOUBLING," upon the condition
(amongst others) that we, the said James Cryer and Samuel Morris, our
executors or administrators, by an instrument in writing under our
or their, or one of our or their hands and seals, 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 calender months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said James Cryer and Samuel Morris,
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 (that is to say) :-
Our Invention consists in certain improved self-acting apparatus for
regulating the tension of the yarn during the building of the bottom of
the cop and until it arrives at its full diameter.

page_text: And in order that our Invention may be fully understood we will
proceed to describe the accompanying Sheet of Drawings, in which,―
Fig. 1 is an elevation of the principal, parts of a self-acting mule to
which our improvements are applied; and Fig. 2 is a front view of part
of the same.
a is the framing of the headstock; b, the front drawing roller; c, the
radial arm or quadrant; d, the strapping or winding band pulley
mounted on the stud of the radial arm or quadrant; and e is the band
passing around the pulley d, then around the driving pulley ƒ mounted
on a stud fixed to the carriage 7, and then around the tightening
pulley / mounted on a stud in the weighted lever i; j are the spindles ;
k, the counterfaller shaft; b, the copping faller shaft; and m, the
winding on chain. To the pulley fis fixed the break pulley f' which is
acted upon by the strapping or winding motion break lever f². All
the parts above enumerated, and the others not particularly referred to.
hereafter, are made in the ordinary manner.
Our improved self-acting apparatus for regulating the tension of the
yarn during the building of the bottom of the cop consists of the
following parts: The worm n is fixed to the strapping or winding band
pulley d, and this worm gears into the wheel o on the short shaft o¹, to
the lower end of which is fixed another worm o³ gearing into the wheelp
on the horizontal square or grooved round shaft p¹ passing under the
carriage and to the required length of the stretch; on this horizontal
shaft is mounted the lever på which is moved to and fro by the carriage.
To the end of this lever is connected an adjustable slide, to which is
secured the lower end of the regulating chain 7 which passes over the
counterfaller shaft k over a pulley on the arm k' fixed to the counterfaller
shaft round the pulley on the ordinary strapping or winding motion
lever f, and the other end of the chain is connected to the arm lon
the copping faller shaft 7. The object of the adjustable slide at the
end of the lever p² is to vary the action of the counterfaller. The arm l
is placed in such a position that when the faller locks it has given off
all its chain, and when the faller begins to wind it draws the chain 9,
which draws the winding motion break lever f' out of motion until the
winding has got past the lowest point on the cop, consequently driving
the regulating motion to the latter end of the winding on.

page_text: In Fig. 1 the parts are shewn in the positions they occupy when the
carriage is running in, and when the bottom of the cop is about half
made the winding motion break lever f' is in contact with the break
pulley f', consequently the band e is carried forward with the carriage
to impart motion to the strapping or winding band pulley d. As the
regulating screw on the quadrant or radial arm c is turned round by the
ordinary strapping or winding band e to wind the nut upwards the
horizontal shaft p' is moved slowly partly round by the worms and
wheels above described, and in so doing the lever p² on the horizontal
shaft p' is drawn downwards to tighten the regulating chain q, thereby
keeping the yarn at the proper tension.
By means of this improved apparatus the counterfaller wire is held in
the desired position at the end of the stretch so as to prevent any slack
yarn when the winding faller is unlocked, thereby avoiding snarls.
Fig. 3 represents a modification of our Invention. Instead of the
worms and wheels above described for actuating the horizontal shaft p¹
it is turned round when required by a mitre pinion on the band
strapping pulley & gearing into a similar pinion on the end of the
shaft p'; on this shaft is also mounted the bevel pinion p³, which slides
to and fro with the carriage and transmits motion to the screw » which
passes through a swivel nut in the lever p² to which the end of the
regulating chain q is attached. The lever p² is mounted on a stud fixed
to the carriage.
Fig. 4 represents another modification of our Invention. In this
instance a toothed chain e' of the ordinary description is used instead of
the band e. This chain imparts motion to the star wheel ƒ when
required, and to this wheel is fixed a worm gearing into the wheels,
fixed to the same shaft as the worm &' gearing into the wheel which is
fixed to the boss of the lever p².
Fig. 5 represents another modification of our Invention. In this
arrangement a mitre pinion on the star wheel f gives motion to the
screw r, the nut of which swivels in the lever på, as in Fig. 3.
Having thus stated the nature of our Invention, and described several
modes of performing the same, we wish it to be understood that we do
not intend to limit ourselves to the details given, as they may be con-
siderably modified according to the peculiar construction of the self-
acting mule to which our improvements are applied; and we claim, the

page_text: improved self-acting apparatus described and shewn for regulating the
tension of the yarn during the building of the bottom of the cop and
until it arrives at its full diameter, and particularly the lever marked p³
and the parts acting in combination therewith.
In witness whereof, we, the said James Cryer and Samuel Morris,
have hereto set our hands and seals, this Twenty-seventh day of
June, One thousand eight hundred and seventy-six.
