& Co., 30, Boulevard Magenta, Paris, in the Republic of France, for an
Invention of "IMPROVEMENTS IN REGULATOR FOR SPINNING ENGINES,

Germany.
PROVISIONAL SPECIFICATION left by the said Maurice Bauer at the Office
of the Commissioners of Patents on the 7th July 1880.
MAURICE BAUER, Civil Engineer, of the Firm of M. Bauer & Co., 30, Boulevard
Magenta, Paris, in the Republic of France. "IMPROVEMENTS IN REGULATOR FOR
SPINNING ENGINES, SELF ACTING." A communication from Joseph Jaeglé, of
Mulhouse, Alsace, Germany.
This Invention relates to certain improvements in self acting regulator apparatus
for spinning machines.
In carrying the Invention into practice there is employed a carrier with spindle.
A sector with a winch handle fixed on a screw puts the step of the screw rod into
operation upon the sector. To the main support of the regulator is fixed a bar to
stretch the thread, and a similar one to guide it. A rocking lever mounted on the
main support is moved and put in position by the guide bar when the bobbins
placed on the empty spindles have begun to revolve and have too little thread
during their unwinding, whereby the guide bar presses the lever arm which then
comes below the stretching bar, which then engages with a hook in the rocking
lever or a toothed wheel fixed to draw to itself an endless chain which passes over
toothed rollers to and over a toothed wheel (on axis of the sector with its screw
step rod), which is thereby turned a quarter of a circle from bottom to top, and as
this each winding until the bobbins have attained the required size.
The endless chain is tightened by one of the wheels being adjustable in its
bearing. An inclined plane fixed on the bed of the machine raises a bar in
connection with a pivoted catch piece engaging with a rack on the rocking lever,
so as that a spiral spring returns the rocking lever in position for the next winding.
A joint which is in the rocking lever is kept straight by means of another spiral
spring, so that in case there is too little thread during the winding it yields softly
and slightly, and does not give too tight a strain to the thread.

MAURICE BAUER, Civil Engineer, of the Firm of M. Bauer & Company, 30,
Boulevard Magenta, Paris, in the Republic of France. "IMPROVEMENTS IN
REGULATOR FOR SPINNING MACHINES, SELF ACTING." A communication from
abroad by Joseph Jaeglè, of Mulhouse, Alsace, Germany.
This Invention relates to certain improvements in self acting regulator apparatus
for spinning machines of the kind known as self acting mules.
In the Drawing, Figure 1 shews an end elevation partly in section of so much
-of the-mechanism of a self acting mule as is necessary for the clear elucidation of
the present Invention, and Figure 2 a side elevation of the essential. .parts... a.
represents in transverse section the mule carriage with its spindles mounted in the
usual way; b, the sector or quadrant; c, the traversing screw, the turning of which
raises or lowers the traversing nut d in the usual way; e is the main support of the
regulating apparatus; f, the "faller" arm, and g the "counter fuller" arm. Both
arms fand g are extended downwards, as shewn, and carry studs at their lower ends
which come to press on the parts h and ' of the regulating apparatus, as hereinbefore
described; h is a rocking lever mounted on the main support e; it is acted upon by
a spring fixed to the support e, which tends to turn it on its fulcrum in the direction
of the arrow; q is a ratchet segment fixed on the lever h, and into the teeth of which
gears a pawl or click connected with the lever p. The lever h carries at its lower end
-a-stud-round which_another lever h¹ turns. The lever ' consists of two parts
connected together by a joint at 8. Between these two parts-is arranged. .a
spring 8', which tends to keep both parts in a straight line.
Between hand h' there is also a spring h², which tends to keep these two levers
in a straight line. At the lower end of thero is a stud u, on which a small
lever vis free to turn; a slot in this lever takes over the shaft of the ratchet
wheel j.
of
On the same shaft is a chain wheel over which passes a chain t, which then runs
over the chain wheels i, k, l, and also over another chain wheel m loose on the axis
of the quadrant. So long as the mechanism occupies the position shewn in the
Drawing, the inward movement of the carriage causes the ratchet wheel ; and the
chain wheel connected to the same shaft to turn, the chain t remaining stationary.
If the yarn threads become too tight the lower end of the "faller arm "f moves
towards the left hand, and its stud moves the upper end of the lever h backwards
so as to bring the entire lever into a vertical position; the small arm at the upper
end of the lever ¹ then comes against the stud on the lower end of the lever
the "counter faller." By this movement of the parts the lower end of h¹ and the
stud u are moved to the right, and the stud takes into the teeth of the ratchet
wheel j, so as to provent the latter from being turned by the further inward
movement of the carriage. In this manner the chain being held by the teeth of
the chain wheel becomes, as it were, fixed to the carriage, and is drawn by it so as
to turn the chain wheel m on the axis of the quadrant; this chain wheel is
connected to a bevil wheel which gears into another bovil wheel fixed on the screw
spindle c, which is thereby turned and moves the traversing nut d upwards, so as
to relax the winding on chain in a manner that will be readily understood by
persons conversant with this class of spinning machinery. The mechanism is held
in this position by the pawl or lever p taking into the teeth of the ratchet segment q
on the lever h. Towards the end of the inward traverse of the carriage an inclined
plane o pushes up the rod p¹ connected to the lever p, which has its fulcrum on the
support e; the pawl is thereby released from the ratchet segment q, and the whole
mechanism is returned by the springs into the position shewn in the Drawing.

page_text: Having now described the nature of the said Invention, and the manner in
which the same is to or may be carried into effect, I would have it understood that
what I claim is,―
The self acting regulating apparatus for mule spinning machines consisting of
the parts e, f, g, h, h¹, j, p, p, t, o, and a combined, arranged, and operated
substantially as herein before described and illustrated in the Drawing, and for the
purpose set forth.
In witness whereof, I, the said Maurice Bauer, have hereunto set my hand
and seal, this Fifth day of January, in the year of our Lord One thousand
eight hundred and eighty ouo.
