PROVISIONAL SPECIFICATION.
Automatic Take-up Regulators, applicable to Tulle and other Looms.
I, JOSEPH ETIENNE PERRACHON, of 29, Rue Bugeaud, Lyon, in the Republic
of France, Mechanician, do hereby declare the nature of this invention to be as
follows:-
"
In order to regulate the diminishing velocity of the work beam upon which
the finished piece is wound as the, manufacture progresses, various means have
hitherto been employed, especially in tulle looms, all of which present numerous
defects, some because they deteriorate and tear the pieces of tulle during the
manufacture owing to the tractive action of an arrangement or urchin termed the
"herisson which serves to regulate the speed of winding, others because they
require frequent adjustment which has necessarily to be entrusted to the care
and experience of the operative. In this latter case, a single pawl is employed
which the operative displaces when he considers necessary, for the purpose of
actuating at the desired speed some one or other ratchet wheel; in addition to
this the operative is obliged to regulate each time the travel of the operating
lever, in order that the pawl may cause the corresponding wheel to rotate
efficiently.
Now all these defects are obviated by the employment of the automatic regula-
tor which forms the subject of this invention, by means of which the diminish-
ing velocity of the work beam is effected automatically by the increase of size
of the beam itself.
Two constructional forms of this regulator are hereinafter described both of
which are adapted to be employed in tulle looms. The regulator consists of,
a series of parts of which the form, arrangement and mounting vary according
to the special construction of the loom to which they are applied.
In order that the invention may be readily understood, I will now describe
separately each of the types referred to.
In the first form the regulator consists of a guide formed by two curved pallets
bearing lightly upon the work beam of the loom. This guide is pivoted to
an arm mounted at the extremity of a transverse shaft carried by a suitable
support, fixed to the loom. The movements of the said guide are transmitted
by means of a lever mounted at the other extremity of the transverse shaft,
to a longitudinal rod which being connected by means of pin to a vertical rod or
part, imparts to this latter its lateral movement in proportion as the work beam
increases its diameter owing to the winding upon it of the manufactured fabric.
The vertical part terminates at its lower portion in a circular rod sliding in a
pivoted socket carried by a support, and comprises at its upper portion two
axes, one of which enters a slide way in the pawl-carrier whilst the other enters
a slide way in a link which is connected to the framework of the loom by means
of an adjustable bracket.
Driving is effected by means of the aforesaid link which is capable of oscillat-
ing by means of the ordinary lever of the loom which has hitherto served to

page_text: actuate the winding pawl of the work beam, and of which the movement is
utilised for the operation of this novel regulator, its oscillatory movement. being
employed for the actuation of the pawl-carrier by means of the vertical rod or
part and the said link.
Owing to this arrangement, it follows that the ratchet wheels mounted upon
the shaft of the endless screw operating the driving wheel of the work beam,
rotates by a diminishing amount in a direct ratio with the increase of diameter
of the work beam, which, progressively raising the guide, displaces by the same
amount from right to left the lever on the transverse shaft and also the vertical
rod, these two parts being connected one with the other by means of the aforesaid
longitudinal rod.
It will be understood that the movement of the ratchet wheels diminishes
progressively and uniformly in proportion as the axes of the vertical. rod become
displaced from the right to the left hand in their respective slides, participating
as they do in the lateral movement of the said rod produced by the vertical
displacement of the guide which is raised by the gradual increase of diameter
of the work beam, as the manufactured fabric is wound thereon.
Finally it should be stated that by the combined employment of four driving
pawls and of four wheels similarly toothed but of which the arrangement of each
as compared with the other varies by a quarter tooth, first of all the constant
adjustments which have hitherto been necessitated are obviated, in addition
to which regular running without jerks is ensured, the pawls being all of the
same length but only one of them actuating. its corresponding wheel in turn
whilst the three others are running loose.
The second device still further simplifies the operation of the regulator and
enables it to be applied to looms in which, owing to the crowding together of
the parts, it would be difficult to employ the form of regulator described above.
With this object, the guides provided with its two pallets is pivoted to an arm
oscillating around the transverse axis. The movements of the guide are trans-
mitted by means of the lever to the longitudinal rod which carries at one of its
extremities a scale provided with a slide way which enables it to be displaced
along a block which is traversed by the second axis of the aforesaid lever. The
scale is provided with a certain number of divisions which enable the block to
be readily adjusted; when once this block has been placed in the desired position
it is maintained firmly in place by means of a screw or nut.
At its other extremity, the longitudinal rod is made wedge-shaped in such a
manner as to gradually force itself into the mortice of a lever in order to regulate
the travel of this latter. This lever is pivoted at its upper portion to a link
or part attached to the driving lever of the loom, and it is provided with a slide
way enabling the lever to assume any desired position with respect to the link
or part, being limited in its displacement only by the position occupied by the
wedge-shaped extremity of the longitudinal rod.
The lower extremity of the lever is pivoted to a second and bent lever pro-
vided with pawls for engagement with the ratchet wheels. Upon the axis of
Oscillation of this bent. lever is mounted a screw which operates, by means of a
helicoidal wheel, the work beam.
In order to cause the levers to turn to their normal position after each stroke
of the loom, a spiral spring is employed which is fixed on the one hand to the
extremity of the lever carrying the pawls and on the other hand to a metallic
plate maintained by set screws behind a bracket. This metallic plate also serves
to limit the extreme travel of levers which strike against it under the action of
the aforesaid spring.
The apparatus being mounted in the manner described, its operation is the same
as that of the device previously explained. In addition to this, the employment
of an adjustable rod terminating in a wedge-shaped part, presents the further
advantage of regulating immediately, and in a manner which is always certain,
the travel of the driving levers of the pawls, and consequently the velocity of

page_text: rotation of the work beam. It will, however, be obvious that this adjustable
rod may be employed with the first described device without departing from the
principle of the invention.

Automatic Take-up Regulators, applicable to Tulle and other Looms.
I, JOSEPH ETIENNE PERRACHON, of 29, Rue Bugeaud, Lyon, in the Republic
of France, Mechanician, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
"
In order to regulate the diminishing velocity of the work beam upon which
the finished piece is wound as the manufacture progresses, various means have
hitherto been employed, especially in tulle looms, all of which present numerous
defects, some because they deteriorate and tear the pieces of tulle during the
manufacture owing to the tractive action of an arrangement termed the
herisson which serves to regulate the speed of winding, others because they
require frequent adjustment which has necessarily to be entrusted to the care
and experience of the operative. In this latter case; a single pawl is employed
which the operative displaces when he considers necessary, for the purpose of
actuating at the desired speed some one or other ratchet wheel; in addition to
this the operative is obliged to regulate each time the travel of the operating
lever, in order that the pawl may cause the corresponding wheel to rotate
efficiently.
Now all these defects are obviated by the employment of the automatic take up
regulator which forms the subject of this invention by means of which the diminish-
ing velocity of the work beam is effected automatically by the increase in size
of the beam itself.
Two constructional forms of this improved take up regulator are represented
in the accompanying drawing both of which are adapted to be employed in tulle
looms
The device consists of a series of parts of which the form, arrangement and
mounting vary according to the special construction of the loom to which they
are applied.
In order that the invention may be readily understood, I will now describe
the same fully with reference to the accompanying drawings.
The first form of take up regulator shewn in Figures 1 and 2 consists of a
guide A formed by two curved pallets a bearing lightly upon the work beam M
of the loom. This guide A is pivoted to an arm B mounted at the extremity
of a transverse shaft C carried by a suitable support D, fixed to the loom, the
other end of the arm B carrying a counterweight b adapted to regulate the
pressure of the guide A upon the work beam M. The movements of this guide A
are transmitted by means of a lever E mounted at the other extremity of the
transverse shaft C, to a longitudinal rod F which being connected by means of
a pin f to a vertical rod G, imparts to this latter its lateral movement in proportion
as the work beam M carries in diameter owing to the winding upon it of the
manufactured fabric. The vertical rod G terminates at its lower portion in a

page_text: circular rod sliding in a pivoted socket H carried by a support I, and comprises at
its upper portion two axes J and K, one of which J enters a slide way in the pawl-
carrier L whilst the other K enters a slide way in a link N which is connected
to the framework of the loom by means of an adjustable bracket O.
Driving is effected by means of the aforesaid link N which is capable of
oscillating at N¹ by means of the ordinary lever P of the loom which has hitherto
served to actuate the winding pawl of the work beam, and of which the move-
ment is utilised for the operation of this novel regulator, its oscillatory movement
being employed for the actuation of the pawl-carrier L by means of the vertical
rod G and link N.
Owing to this arrangement, it follows that the ratchet wheels R R¹ R² R³
mounted upon the shaft of the endless screw S operating the driving wheel T
of the work beam M, rotate by a diminishing amount in a direct ratio with the
increase of diameter of the work beam, which, progressively raising the guide A,
displaces by the same amount from right to left the lever E and also the vertical
rod G, these two parts being connected one with the other by means of the
rod F.
It will be understood that the movement of the ratchet wheels R R R³ R³
diminishes progressively and uniformly in proportion as the axes J and K.of
the vertical rod G become displaced from the right to the left hand in their
respective slides, participating as they do in the lateral movement of the said
rod G produced by the vertical displacement of the guide A which is raised
by the gradual increase of diameter of the work beam, as the manufactured
fabric is wound thereon.
Finally it should be stated that by the combined employment of four driving
pawls and of four wheels similarly toothed but of which the arrangement of each
as compared with the other varies by a quarter tooth, first of all the constant
adjustments which have hitherto been necessitated are obviated, in addition
to which regular running without jerks is ensured, the pawls being all of the
same length but only one of them actuating its corresponding wheel in turn
whilst the three others are running loose.
The second device represented in Figures 3 and 4 still further simplifies the
operation of the regulator and enables it to be applied to looms in which, owing
to the crowding together of the parts, it would be difficult to employ the form of
regulator described above.
With this object, the guide A provided with its two pallets a is pivoted to
an arm B oscillating round the transverse axis C. The movements of the guide
are transmitted by means of the lever E to the longitudinal rod F which carries
at one of its extremities a scale V provided with a slide way v which enables
it to be displaced along a block X which is traversed by the second axis Z of
the aforesaid lever E. The scale V is provided with a certain number of divisions
which enable the block to be readily adjusted; when once this block has been
placed in the desired position it is maintained firmly in place by means of a
screw or nut Y.
At its other extremity, the longitudinal rod F is made wedge-shaped in such
a manner as to gradually force itself into the mortice of a lever g in order to
regulate the travel of this latter. This lever g is pivoted at its upper portion
to a link m attached to the driving lever P of the loom, and it is provided with
a slide way o enabling the lever g to assume any desired position with respect to
said link m, being limited in its displacement only by the position occupied by
the wedge-shaped extremity of the longitudinal rod F.
The lower extremity of the lever g is pivoted to a second and bent lever L
provided with pawls 7 for engagement with the ratchet wheels R. Upon the
axis of oscillation of this bent lever is mounted a screw S which operates, by
means of a helicoidal wheel T, the work beam M.
In order to cause the levers L and g to return to their normal position after
each stroke of the loom, a spiral spring u is employed which is fixed on the

page_text: .
one hand to the extremity of the lever carrying the pawls and on the other
hand to a metallic plate c maintained by set screws behind a bracket d, as
represented in Figure 4. This metallic plate also serves to limit the extreme
travel of levers which strike against it under the action of the aforesaid spring u.
The apparatus being mounted in the manner described, its operation is the same
as that of the device previously explained. In addition to this, the employment
of an adjustable rod terminating in a wedge-shaped part, presents the further
advantage of regulating immediately, and in a manner which is always certain,
the travel of the driving levers of the pawls, and consequently the velocity of
rotation of the work beam. It is of course obvious that this adjustable rod
may be employed with the first described device.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
1. In automatic take up regulators for tulle and other looms, a guide adapted
to bear lightly upon the fabric or material manufactured, levers connected to said
guide, said levers actuating ratchet or other wheels, in combination with means
whereby the diminishing velocity of rotation of the work or receiving beam is
automatically produced during the whole course of operation of manufacture by
the increase in diameter of the work or receiving beam substantially as herein-
before described and illustrated by the accompanying drawings.
2. An automatic take up regulator for tulle and other looms constructed
arranged and operating substantially as hereinbefore described and illustrated
with reference to the accompanying drawings and for the purpose specified.
