1 JOSEPH JÖRG of Cornimont, Vosges in the Republic of France, Manufacturer, do
hereby declare the nature of this invention to be as follows.
This invention relates to mule spinning machines and consists in certain mechanism
hereinafter described to be combined with the sector in the said machines which,
having a continual movement regulates the thread, that is to say, gives to the spindles
the necessary rotary movement for the winding of the thread by means of a chain
connected to a sleeve attached to the sector and adjustable in a radial direction on the
latter.
The improved mechanism is destined to automatically adjust in a novel manner the
position of said sleeve so that the cop is correctly wound, especially when the yarn
slackens.
The regulator is composed of the following parts: A gudgeon is arranged on the
axis of the sector and on the latter is supported a double grooved pulley having an
eccentrically placed pin thereon serving as a pivot for a lever which supports a pawl
engaging in a ratchet wheel formed as an integral part with a hevelled wheel,
supported also by the said gudgeon. The bevelled wheel on the gudgeon gears with
a bevelled wheel on a shaft, journalled in a radial direction on the sector or on a
support fixed thereto, its inner end resting in a step bearing on the gudgeon aforesaid.
A portion of the said shaft is screw threaded and carries the sleeve to which the chain
before mentioned is attached.
This chain is fastened to a lever pivoted on the sector and carrying the ordinary
chain in connection with the barrel on the mule carriage. There is also a toothed
wheel with ratchet and pawl and grooved pulley on a gudgeon on the sector, said
grooved pulley connected by a band wound thereon with the grooved pulley on the
gudgeon at the axis of the sector. The toothed wheel last mentioned serves as a
counter and hand regulator. The pawl is held in engagement with the ratchet at the
D

page_text: axis of the sector by a sliding rod, held against the tail of the pawl by a finger
engaging behind a projection on the rod. When the thread becomes too slack, the
faller rises higher than the desired point, this causes a rod, to .descend on the finger
last mentioned. to liberate the same and a spring throws the sliding rod out of engage-
ment with the pawl. The latter falls and the regulator is thrown out of engagement
until the faller resumes its first position, the parts are then returned to their previous
position by a projection on the mule carriage abutting against the sliding rod when
the carriage is moved back, pushing back the sliding rod and allowing the finger
holding the same to fall by its own weight into its previous position.

Improvements in or relating to the Winding of the Cops in Mule
Spinning Machines.
I JOSEPH JÖRG of Cornimont, Vosges, in the Republic of France, Manufacturer
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 self acting mule spinning machines in which the spindles
are revolved from a barrel operated by a chain wound thereon and attached to a
continually moving sector that is to say to a sleeve engaging on a screw threaded
shaft journalled radially thereon whereby the point of attachment of the chain on the
sector may be adjusted in a direction radially on the sector according to the require-
ments of winding.
The invention consists in the addition of certain mechanism as hereinafter described
for the regulating of the winding and more especially in case of slackness in the
yarn.
Reference being made to the accompanying drawings.
Fig. 1 is an end elevation of the sector, and paris relating thereto.
Fig 2 is a side elevation thereof showing also part of the mule carriage.
Fig 3 is a plan view of part of the mechanism.
On the axis of the sector S is fixed a gudgeon A and on the latter is supported the
double grooved pulley Don which is eccentrically fixed a small gudgeon o supporting a
lever c pivoted thereon, the purpose of which is to support a gudgeon F on which the
pawl is pivoted. a is a step bearing in which the end of the screw threaded shaft 1
rests. B is a wheel having bevelled teeth and ratchet teeth, being the pawl to the
ratchet teeth. The collar N holds the parts on the gudgeon A.
A cast frame H is fixed to the sector and on the said frame is a bracket / carrying
a gudgeon on which is supported a grooved pulley d with ratchet teeth thereon, e is
a pawl thereto, and fan arm carrying a gudgeon on which said pawl is pivoted.
is
a toothed or serrated wheel serving as a counter or indicator of the position of the
apparatus. The pulleys I and d are connected by a belt wound on one of the grooves
of the pulley D and on the pulley d as shown in Fig. 1. The other groove on the
pulley D carries wound thercon a belt, terminating in a weight, so that the weight
may act to wind up slack in the belt connecting the pulleys. The moment of the
weight acting to revolve the pulley and so keep the latter belt in tension. I is the
screwthreaded shaft journalled in a bearing on the frame H and carrying the sleeve G
in engagement thereon. I is a shaft serving as a continuation of the shaft I, and
connected thereto by a pin 7 and carrying an endless screw engaging with the toothed
wheel y. and k are spur wheels for revolving the shaft by hand."
The chain t attached to the sleeve G is connected to the lever m to which the usual
chain for driving the barrel is attached, n are parallel guides to the sleeve G.

page_text: On suitable standards R R R111 fastened to the floor is supported the sliding rod u
abutting against the pawl and held in place by the lever against the pressure of the
spring P is a rod attached by chain to the faller 2.
When the thread becomes slack, the faller wire rises higher than the point desired,
in such case the rod immediately falls by its own weight and arrives on the lever v
disengaging the rod u which is then moved by the spring P, that it no longer serves
as an abutment for the pawl and the latter is rendered inoperative.
The regulator therefore stops until the faller resumes its original position.
When the mule carriage moves back, the projection e¹, thereon arrives against the
pink on the rod u, (Fig. 3) and pushes it back until the lever falls behind its pro-
tection on the rod u and holds the same in place.
The regulator remains stationary when the heart of the cop is finished. In this
case the workman therefore has to set the apparatus in motion. In my system it is
sufficient to take out the bolt coupling the spindles and I and to move back by
one or two teeth according to necessity the ratchet wheel B. The apparatus is then.
again set in action and the sleeve G descends again on the spindle I drawing with it
by means of the chain m the chain of the barrel; this movement continues until the
cop is completed.
Before commencing a cop, the sleeve G is moved back to its point of departure by
turning the ratchet wheel B, and the threaded shaft of the sector is therefore carried
back into its first position.
Then the wheel B is put back for the same amount as it was moved at the moment
of finishing the heart of the cop and the pin 7 is replaced connecting the shafts I
and the apparatus is then ready to start.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
In mule spinning machines:
1. The combination with the sector S of the regulator for moving the sleeve G
substantially as illustrated and described.
2. The combination of the pawl with the faller so that it is set out of action by
rise of the faller wire substantially as set forth.
