Victoria Street, London, E.C., Consulting Engineers and Chartered Patent Agents,
do hereby declare the nature of this invention to be as follows:-
In the manufacture of textile goods, whether in preparation, spinning or twist-
ing, great inconvenience is brought about by the breaking of the threads or
meshes.
In the first place there is the waste of material caused by the continuance
of the feeding forward of the thread or by the feeding cylinder after breakage
has taken place, so that the material delivered between the time of breakage
and of re-attachment, is wasted. Secondly, the thread or mesh can become rolled
around the feeding cylinder and produces what is called a knot, which causes
great waste, whether by the deterioration of the material or by becoming en-
tangled with neighbouring threads and causing them to break.
But the greatest inconvenience is caused when the broken thread becomes united
with a neighbouring thread, forming what is called a "marriage." The double
thread formed in this way does great harm to the texture and occasions great
waste when it is discovered.
In order to avoid the above inconveniences I employ the device which forms
the subject of is application.
When a thread or mesh breaks, the feeding cylinder stops and revolving no
longer, the delivery of the thread ceases.
The parts of this device are for each spindle as follows:-
1st. A clutch cylinder adjusted on the shaft, carrying a projection on one
end and having its end cut in the form of a portion of a spiral.
2nd. A spiral spring which pushes the clutch against
3rd. A driving collar made solid with the shaft and also carrying a projection.
4th. A lever for guiding the thread pivotted about an axis, having at its front
end a fork or claw for guiding the thread and at its rear end a counter weight,
it carries also at its centre a projection.
5th. A bolt which can displace itself in a direction longitudinal of the machine,
so as to prevent the levers tipping over during the working of the machine.
The device operates as follows:
When the machine is working the spring pushes the clutch against the collar
producing the engagement of the tenons or projections which are on the clutch
and the collar and therefore the engagement of the clutch is effected.
The thread which is delivered between the clutch cylinder and the pressure
roller passes over the guiding fork of the lever and by its tension inclines the
latter in a forward position. If the thread is broken, the lever being only thus
retained hinges backward and brings its projection against the helical end of

page_text: the clutch, this latter draws back and ceases to receive its movement from the
collar, and therefore the cylinder stops turning and delivering the thread.
In order to put the apparatus into action after having reattached the thread
it is sufficient to rest the thread on the lever.

Improvements in Preparing, Spinning, Twisting, and like Machines.
A communication from abroad by AUGUSTE LEPOUTRE, of 19, Rue Cambon, Paris,
France, Manufacturer.
I, REGINALD WILLIAM JAMES, of the Firm of Fell and James, of 1, Queen
Victoria Street, London, E.C., Consulting Engineers and Chartered Patent Agents,
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:
-
In the manufacture of textile goods, whether in preparation, spinning or twist-
ing, great inconvenience is brought about by the breaking of the threads or
meshes.
In the first place there is the waste of material caused by the continuance
of the feeding forward of the thread or by the feeding cylinder after breakage
has taken place, so that the material delivered between the time of breakage
and of re-attachment, is wasted. Secondly, the thread or mesh can become rolled
around the feeding cylinder and produces what is called a knot, which causes
great waste, whether by the deterioration of the material or by becoming en-
tangled with neighbouring threads and causing them to break.
But the greatest inconvenience is caused when the broken thread becomes united
with a neighbouring thread, forming what is called a "marriage." The double
thread formed in this way does great harm to the texture and occasions great
waste when it is discovered.
In order to avoid the above inconveniences I employ the device which forms
the subject of this application.
When a thread or mesh breaks, the feeding cylinder stops and revolving no
longer, the delivery of the thread ceases.
In order that this invention may be the better understood I will now proceed
to describe the same in relation to the drawings hereunto annexed reference being
had to the letters and figures marked thereon.
Figure 1 shows front and side elevations of the apparatus when the thread
is intact.
Figure 2 shows similar views when the thread has broken.
The parts of this device are, for each spindle, as follows
1st. A clutch cylinder M adjusted on the shaft A carrying a projection Con
one end and having its end cut in the form of a portion of a spiral.
2nd. A spiral spring R which pushes the clutch cylinder M against
3rd. A driving collar B made solid with the shaft A and also carrying a
projection D.
4th. A lever for guiding the thread pivotted about an axis E, having at its
front end a fork or claw for guiding the thread and at its rear end a counter-
weight, it carries also at its centre a projection T.

page_text: The device operates as follows:-
When the machine is working, the spring R pushes the clutch cylinder M
against the collar B producing the engagement of the tenons or projections which
are on the clutch cylinder and the collar and therefore the engagement of the
clutch cylinder M is effected.
The thread which is delivered between the clutch cylinder and the pressure
roller passes over the guiding fork of the lever and by its tension inclines the
latter in a forward position. If the thread is broken, the lever being only thus
retained, hinges backward and brings its projection against the helical end of
the clutch cylinder M, this latter draws back and ceases to receive its movement
from the collar B, and therefore the cylinder stops turning and delivering the
thread.
In order to put the apparatus into action after having reattached the thread,
it is sufficient to rest the thread on the lever.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what
I claim is:-
1st. In preparing, spinning twisting and like machines a device adapted to
stop the feeding cylinder supplying the thread to each spindle, by the release of
tension of the thread, when the said thread breaks, in order to prevent the loss
of thread and the formation of marriages, substantially as described.
2nd. A device as claimed in Claim 1 constructed and arranged, substantially
as described and illustrated in the accompanying drawings.
