We RICHARD LEACH HOLT of 3 Adelaide Street Southport in the County of
Lancaster Mechanic, and JAMES CARTER of Atlas Works Stalybridge in the County
of Chester Brass Founder do hereby declare the nature of this invention to be as
follows:
This invention relates to the construction of self-acting mules used for spinning
cotton and other fibrous substances and the object of the invention is to equalize by
automatic means the tension of the yarn during the winding on so as to prevent the
formation of "snarls."
For this purpose we employ in connection with the finger on the "counter-faller
shaft," the following arrangement, which is entirely automatic, and is so regulated, that
the action of this improved apparatus is gradually increased so as to compensate for
the increased tendency to "snarl" as the winding-on proceeds.
Instead of resting on the usual stud or support the counterfaller finger rests upon
a long lever one end of which is pivotted to a bracket bolted to the headstock.
The other end of this lever is supported by means of a short foot or projection,
which rests upon a stepped cam or "snail" mounted on a stud carried by the same
bracket.
The upper side of this lever is so formed that as the spindle carriage runs up
to the rollers if there is too much "slack" in the yarn the counterfaller finger comes
into contact with the surface of the said lever which causes it to draw the counter-
faller wire into such a position as to prevent the "snarling" of the yarn.
It is well known however to self-actor "minders "that the tendency to "snarl" is
at a minimum when a fresh set of cops is commenced and that this tendency increases
as the building up of the cop proceeds, and in order to compensate for this, the
following automatic arrangement is employed to gradually increase the action of the
counter-faller wire as the winding on proceeds.
The free end of the lever as before mentioned is supported by a stepped cam or
snail to which is attached a second lever pivotted to the same bracket and provided
with a spring which has a constant tendency to raise the same but which is held down
by a stud or projection from a finger on the faller shaft.

page_text: When this second or lower lever is at its lowest position (as it is when commencing
a set of cops) the stepped cam or snail is held in such a position that its lowest step is
beneath the projection under the first named or upper lever and this lever is
consequently at its position of least action on the counter-faller finger, but as the
winding proceeds the faller finger is raised higher and allows the spring to raise the
second lever higher also and thus to bring a higher step of the cam or snail beneath
the projection of the first named or upper lever and thus increase the action of the
counter faller wire. By the time that the cop is finished or nearly so the highest step
of the cam would have been brought beneath the foot of the first named or upper
lever and the action of the counterfaller would be at the maximum point.
In order to allow the counter faller wire to be raised above the point of the spindle
as is necessary after piecing up when there no coils of yarn on the point of the
spindles, the end of the counterfaller finger does not rest directly upon its lever, but
is provided with a short tongue which is jointed to its end from which it hangs down
and supports the finger but upon moving this tongue out of the way the finger
can be lowered sufficiently to raise the counterfaller wire above the point of the
spindle.

page_text: Improvements in Self-acting Mules.
We RICHARD LEACH HOLT of 3 Adelaide Street Southport in the County of
Lancaster Mechanic and JAMES CARTER of Atlas Works Stalybridge in the County
of Chester Brass Founder do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :—
This invention relates to the construction of self-acting mules used for spinning
cotton and other fibrous substances, and the object of the invention is to equalize by
automatic means the tension of the yarn during the "winding on so as to prevent
the formation of "snarls," the cause of "snarls" being that when the counter-faller gets
too high the yarn becomes slack.
To obviate this we employ in connection with the finger on the counterfailer-shaft
an arrangement which is entirely automatic, and is so regulated that the action of this
improved apparatus is gradually increased so as to compensate for the increased
tendency to snarl as the winding-on" proceeds.
"
The manner in which our invention is to be performed or carried into practical effect.
will be readily understood on reference to the drawings hereunto annexed and the
following explanation thereof.
Fig. I is an elevation (partly in section) of so much of a self acting mule as is
necessary to illustrate our invention and Fig. 2 is a slight modification (hereinafter
more particularly referred to) of a portion of the same, a is part of the framing of
the headstock of the mule, is the counter faller shaft and the faller shaft. The
position of the counter-faller d, faller e spindle and lower spindle rail gare shown
in dotted lines is the faller finger and i the counter-faller finger.
C
The latter instead of being raised by a stud or support is acted on by a lever k
one end of which is pivoted to a bracket bolted to the headstock a or attached to the
floor: the other end of this lever is supported by means of a stud or projection m,
which rests upon a snail forming part of a lever o mounted on a stud carried by
the same bracket or instead of a snail we sometimes employ a stepped cam 7 as
shown at Fig. 2.

The upper side of the lever is so formed that as the spindle carriage runs up to
the rollers, if there is too much slack in the yarn the counter-faller finger i
comes into contact with the surface of the said fever which causes it to draw
the counterfaller wire into such a position as to prevent the "snarling" of the yarn.
It is! well known however to self-actor "minders" that the tendency to snarl is at a
minimum when a fresh set of cops is commenced and that this tendency increases as
the building up of the cop proceeds, and in order to compensate for this, the following
automatic arrangement is employed to gradually increase the action of the counter-
faller wire as the winding-on proceeds.
The.free end of the lever as before mentioned is supported by a stud m resting on
the stepped cam y or snail n which is attached to or forms part of a second lever o

tendency to raise the same, but which is held down by a stud or projection from
the faller finger h, which gradually causes the finger to rise as the cop is.
built up.
When this second or lower lever o is at its lowest position (as it is when
commencing a set of cops) the stepped cam g or snail n is held in such a position
that its lowest step or portion of the curve is beneath the stud or projection m on
the first named or upper lever, and this lever is consequently at its position of
least action on the counterfaller finger but as the winding proceeds the faller
finger his raised higher and allows the spring to raise the second lever o higher
also, and, thus to bring a higher step or portion of the cam 7 or snail.n beneath
the projection or stud m, on the first named lever k and thus increase the action of the
counter faller wire.
By the time that the cop is finished or nearly so the highest step or portion
of the cam or snail would have been brought beneath the stud m of the lever k
and the action of the counterfaller would be at the maximum point.
In order to allow the counterfaller wire to be raised above the point of the spindle
as is necessary after piecing up when there are no coils of yarn on the point of the
spindles, the end of the counterfaller finger instead of resting directly upon its lever
may be provided with a short tongue which is jointed to its end from which it hangs
down and supports the finger, but upon moving this tongue out of the way the finger.
can be lowered sufficiently to raise the counterfaller wire above the point of the
spindle, but the same object may be attained by pressing down the end of the lever >>
so as to bring the lowest portion of the cam or snail under the stud or projection mon
the lever k
It will be evident that instead of operating the stepped cam or snail n (which
supports the lever k) by means of a finger h fixed upon the faller shaft c the same
effect will be produced if it be operated by any other convenient part of the faller or
copping mechanism, the object being to cause the position of the counterfaller wire to
he controlled automatically by means of the faller or copping mechanism.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
"
The combination with the counterfaller finger, of a lever the free end of which is
supported by a stud or projection resting upon a stepped cam or snail, the position of
which cam or snail is automatically adjusted as the "winding on proceeds by means
of a finger or its equivalent connected to and operated by the faller shaft, or by any
other convenient portion of the faller or copping mechanism, substantially as herein-
before described and illustrated by the annexed drawings.
