IMPROVEMENTS IN MULES FOR SPINNING
Year: 1880

page_text: PROVISIONAL SPECIFICATION left by the said Robert Redford at the Office
of the Commissioners of Patents on the 18th February 1880.
ROBERT REDFORD, Sub-manager for the Reddish Spinning Co., Limited, Reddish,
near Stockport. "IMPROVEMENTS IN MULES FOR SPINNING."
This Invention consists in an apparatus for effectually preventing snarls in yarn
through careless winding, or in lifting the fallers with the yarn too slack, the
unlocking of the faller being governed by the tension of the yarn. In the ordinary
construction of the mule the unlocking of the faller is governed by the faller leg
striking against the fixed bracket. Snicks or snarls are made by slackening the
yarn too much by means of the quadrant. In my Invention I control the unlocking
of the faller by means of an automatic arrangement governed by the tension of
the yarn on the lower faller, thus being less dependant on the skill or care of the
minder.
On the under faller is a lever, and on the lower end of this lever is a chain
connected with an incline slide. The slide being fixed in the faller leg the rising
or falling of the slide causes the top faller to unlock sooner or later as the yarn is
tight or slack; thus the action of the top faller is controlled by the tension of the
yarn, making it impossible to put in snicks or snarls into the yarn through defective
winding.

SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Robert Redford in the Great Seal Patent Office on the 17th August
1880.
ROBERT REDFORD, Sub-manager for the Reddish Spinning Company, Limited,
of Reddish, near Stockport. "IMPROVEMENTS IN MULES FOR SPINNING.'
My Invention consists in causing the unlocking of the faller to be governed by
the tension of the yarn. I control the unlocking of the faller by means of an
automatic arrangement governed by the tension of the yarn on the lower faller,
thus being less dependant on the skill or care of the minder. On the same shaft
as and moving with the under faller is a lever, and attached to the outer end of
this lever is a chain connected to a sliding plate which slides on a fixed bar or
bracket on the top faller leg. The rising or falling of the slide causes the top
faller to unlock sooner or later as the yarn is tight or slack.
And in order that my Invention may be fully understood, and readily carried
into effect, I will describe the accompanying Drawing, reference being had to the
letters marked thereon. a is the under faller shaft; a' is the under faller; and a
is a lever fixed on the shaft a; b is the top faller shaft; b' is the top faller; and c
is the faller leg, on which is fixed a bar or bracket c', on which slides an angular
plate c; this plate is connected by a chain to the lever a³; d is a lever which
swings on a stud on the faller leg, and on d is fixed a pin e, which rests against
the edge of the plate c²; g is an adjustable stop piece, against which the extremity
of the lever d is pressed when the carriage runs in and the yarn is tight; is the
bowl on which the faller leg rests when it is locked.
.
The mode of operation is as follows:-When the carriage runs in if the yarn is
slack the under faller a¹ is raised, and consequently the lover a² is depressed, and
the plate c is so low that although the point of the lever d may be against the stop
piece g the pine does not bear sufficiently against the plate c³ to knock the faller
leg off the bowl h. When the yarn is tight it depresses the under faller a', and
thus raises the lever a², which by the chain flifts the plate c³, and the point of the
leverd being held by the stop piece g the plate c² acts as a wedge between the
pin e and the bar b¹, and forces tho faller leg off the bowl h, and reverses
the carriage.
Having thus stated the nature of my Invention, and described the manner of
performing the same, I wish it to be understood that I do not limit myself to the
details given, as the same may be varied or modified, and I declare that I claim,
causing the unlocking of the faller to be governed by the tension of the yarn, and
the mechanism for effecting the same, substantially as shewn and described.
In witness whereof, I, the said Robert Redford, have hereunto set my hand
and seal, this Fourteenth day of August, One thousand eight hundred and
