Improvements in Embroidering Machines.
We EMILE CORNELY and ROBERT CORNELY, manufacturers, of 87 faubourg
St. Denis, Paris, of the firm of E. Cornely & fils, do hereby declare the nature of
this invention to be as follows:-
:-
Our invention relates to improvements in embroidering machines.
In the Patents No. 212 of 19th January 1876 and No. 2890 of 16th July 1879 a
machine has been described and claimed for winding a second thread around the
needle or the stitch of an embroidering machine for the purpose of producing a
cording work. Since that time modifications have been made to employ a large
thread bobbin on the central tube of the machine but which arrangements were not
without inconveniences.
When the central bobbin was arranged to turn on the lower end of the nipple
tube, it covered more or less the work, it could not be detached from the machine
for spooling the thread and besides the organs of the feed motion were so far above
the cloth as to render the feed more or less imperfect; when the bobbin was set to
turn on the upper part of the central tube, its thread was led down through the said
central tube and through the nipple tube which latter had then to turn with it and
with the nipple, whereby certain kinds of work could not be executed at all.
The object of the present improvement is to obviate the above difficulties.
Figure 1 of the accompanying Drawings represents a front view of the head of
the machine with a section through the central tube.
The other figures are detached views hereafter to be referred to.
To obviate the difficulties above stated it was found necessary to make certain
modifications in the organs of the "Bonnaz" embroidering machine on which all
the organs which produce the stitch and the feed are connected with the central
tube, therefore in the present improvements the organs of the feed are set upon a
separate shaft as will be described hereafter and as represented at fig. 1.
A, represents the needle bar of the machine, to which the needle B is secured.
The needle bar A is secured to the tube D, by means of the screw a, and the tube D
is operated by the ordinary heart slide for its up and down motion.
E E' represent
the nipple tube to which the nipple b is secured in the ordinary manner and which
nipple is indispensable to all machines which work with a needle hook.
The nipple
tube is composed of two parts E and E2 which are coupled together by means of the
hook shaped ends c and d represented at fig. 1 and in detached views at fig. 2. The
two parts of the nipple tube when coupled together cannot separate one from the other
after the needle bar A has been introduced into them, as it fills up the entire hollow
of the nipple tube; the latter is operated by means of its slide (figs. 1, 2 and 3)
in the usual manner, the fork H of the slide F entering into the collar g of the
nipple tube (figs. 1, 2 and 3).
G represents the pinion to which the revolving thread carrier C is secured as
described and shown in the letters patent mentioned above, the pinion. G turns within
the flange I, of the casting and has a revolving motion imparted to it by means of
gearings of any description from the main shaft of the machine, it is perforated
through the entire length of its hub, and through the hole h thus formed is passed
the thread n of the spool K which turns on the upper part E of the nipple tube. The
thread guide holder L is secured to the hub of pinion G, and the thread from
bobbin K passes through the thread guides 2 and 3 and the openings i and h, down
into the eye of the revolving thread carrier C.
This arrangement permits the bobbin to be easily withdrawn from or inserted into
the machine for renewing its thread, for by withdrawing the needle bar A the part E,
together with its bobbin can be taken from the fork H, and from the part E.

page_text: In this arrangement the nipple 6 does not turn with the revolving thread carrier
because the thread does not pass through the interior (as is the case in some
machines) but to the exterior of the nipple tube E2 in its way from the bobbin K, and
the advantage of this will be fully appreciated in reference to the machine shown and
described in specification to letters patent No. 2597 of May 24-1883 for producing
various kinds of work, and where a revolving thread carrier is employed in combina-
tion with several needles; it is certain that two or more needles B B2 passing through
the same nipple b fig. 4 could not work at all if the nipple was to turn together
with the rotating thread carrier in its revolving motion, nor would it be possible to
execute the work represented at fig. 5 where a cord M is secured to the seam of the
machine by means of a thread x, which is wound around said seam and around the
cord by means of the revolving thread carrier C, for if the nipple b would revolve with
the thread carrier C the cord M passing through the guide 4 of the nipple would be
constantly turned around the needle and the work described and shown in the speci-
fication of patent 2597 of May 24th 1883 could not be executed.
But for executing those kinds of work the nipple 6 not only must not turn with the
revolving thread carrier C, but it must also be made to be governed by the crank-
handle of the machine so as to turn in conformity with the direction of the feed as
described in specification 2597 of 1883, which in the present machine is obtained in
the following manner. The movement of the crank handle is transmitted by any
kind of gearing to the pinions N, O, P, Q and R which latter turns the tube D by
means of a projection in its interior bearing against a flat side 5 of the tube D and a
similar arrangement exists at 6, between the needle bar A and a projection in the
interior of the nipple tube E' which is thus turned by the motion of the crank handle
of the machine.
The slide F can be raised by means of the lever S to lift the nipple tube E E' to
facilitate the operation of the setting or of withdrawing the bobbin K.
As above mentioned the organs of the feed U, V, and W are set upon a separate
shaft T and the part W is operated by means of the slide X, while the slide Y
operates the foot bar Z and its foot m; as the organs U, V and W are very near to
the material the feed thus obtained is very perfect.
In the machines in which the nipple tube revolves with the revolving thread carrier
the collar and the fork H are subject to a rapid wear by reason of the constant
rotation of the collar g and thus the regular operation of the nipple is impeded, which
difficulty cannot occur in the present machine."

Improvements in Embroidering Machines.
We EMILE CORNELY and ROBERT CORNELY, Manufacturers, of 87 Faubourg
St. Denis, Paris, of the firm of E. Cornely & fils, do hereby declare the nature of
this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement:-
Our Invention relates to improvements in embroidering machines.
In the Patents No. 212 of 19th January 1876 and No. 2890 of 16th July 1879
a machine has been described and claimed for winding a second thread around the
needle or the stitch of an embroidering machine for the purpose of producing a
cording work. Since that time modifications have been made to employ a large
thread bobbin on the central tube of the machine but which arrangements were not
without inconvenience.
When the central bobbin was arranged to turn on the lower end of the nipple
tube, it covered more or less the work, it could not be detached from the machine
for spooling the thread and besides the organs of the feed motion were so far above
the cloth as to render the feed more or less imperfect; when the bobbin was set to

page_text: turn on the upper part of the central tube, its thread was led down through the said
central tube and through the nipple tube which latter had then to turn with it and
with the nipple, whereby certain kinds of work could not be executed at all.
The object of the present improvement is to obviate the above difficulties.
Figure 1 of the Drawings left with the Provisional Specification represents a front
view of the head of the machine with a section through the central tube.
The other figures are detached views hereafter to be referred to:
To obviate the difficulties above stated it was found necessary to make certain
modifications in the organs of the "Bonnaz" embroidering machine on which all
the organs which produce the stitch and the feed are connected with the central
tube, therefore in the present improvements the organs of the feed are set upon a
separate shaft as will be described hereafter and as represented at figure 1.
A, represents the needle bar of the machine, to which the needle B is secured.
The needle bar A is secured to the tube D, by means of the screw a, and the tube D
is operated by the ordinary heart slide for its up and down motion. E E' repre-
sents the nipple tube to which the nipple 6 is secured in the ordinary manner and
which nipple is indispensable to all machines which work with a needle hook. The
nipple tube is composed of two parts E and E3 which are coupled together by means
of the hook shaped ends c and d represented at fig. 1 and in detached views at
fig. 2. The two parts of the nipple tube when coupled together cannot separate one
from the other after the needle bar A has been introduced into them as it fills up the
entire hollow of the nipple tube; the latter is operated by means of its slide F
(figs. 1, 2 and 3) in the usual manner, the fork H of the slide F entering into the
collar g of the nipple tube (figs. 1, 2 and 3).
G represents the pinion to which the revolving thread carrier C is secured as
described and shown in the Letters Patent mentioned above, the pinion G turns
within the flange I, of the casting and has a revolving motion imparted to it by
means of gearings of any description from the main shaft of the machine, it is per-
forated through the entire length of its hub, and through the hole thus formed is
passed the thread n of the spool K which turns on the upper part E of the nipple
tube. The thread guide holder L. is secured to the hub of pinion G, and the thread
from bobbin K passes through the thread guides 2 and 3 and the openings i and h,
down into the eye of the revolving thread carrier C.
This arrangement permits the bobbin to be easily withdrawn from or inserted
into the machine for renewing its thread, for by withdrawing the needle bar A the
part E, together with its bobbin can be taken from the fork H, and from the
part
In this arrangement the nipple 6 does not turn with the revolving thread carrier
because the thread does not pass through the interior (as is the case in some
machines) but to the exterior of the nipple tube E2 in its way from the bobbin K,
and the advantage of this will be fully appreciated in reference to the machine shown
and described in Specification to Letters Patent No. 2597 of May 24th 1883 for
producing various kinds of work, and where a revolving thread carrier is employed
in combination with several needles; it is certain that two or more needles BB2
passing through the same nipple 6 fig. 4 could not work at all if the nipple 6 was to
turn together with the rotating thread carrier in its revolving motion, nor would it
be possible to execute the work represented at fig. 5 where a cord M is secured
to the seam of the machine by means of a thread, which is wound around said
seam and around the cord by means of the revolving thread carrier C, for if the
nipple would revolve with the thread carrier C the cord M passing through the
guide 4 of the nipple would be constantly turned around the needle and the work
described and shown in the Specification of Patent 2597 of May 24th 1883 could not
be executed.
But for executing those kinds of work the nipple 6 not only must not turn with
the revolving thread carrier C, but it must also be made to be governed by the
crank handle of the machine so as to turn in conformity with the direction of the
feed as described in Specification 2597 of 1883, which in the present machine is

page_text: obtained in the following manner.
The movement of the crank handle is transmitted
by any kind of gearing to the pinions N, O, P, Q and R which latter turns the
tube D by means of a projection in its interior bearing against a flat side 5 of the
tube D and a similar arrangement exists at 6, between the needle bar A and a pro-
jection in the interior of the nipple tube E2, which is thus turned by the motion of
the crank handle of the machine.
The slide F can be raised by means of the lever S to lift the nipple tube E E² to
facilitate the operation of the setting or of withdrawing the bobbin K.
As above mentioned the organs of the feed U, V, and W are set upon a separate
shaft T and the part W is operated by means of the slide ✗, while the slide Y
operates the foot-bar Z and its foot m; as the organs U, V and W are very near to
the material the feed thus obtained is very perfect.
In the machines in which the nipple tube revolves with the revolving thread
carrier the collar g and the fork H are subject to a rapid wear by reason of the
constant rotation of the collar g and thus the regular operation of the nipple is
impeded, which difficulty cannot occur in the present machine.
On the accompanying Sheet of Drawing,
Figure 6 and Figure 8 represent certain modifications in those shown and
described in Figure 1 and on which thinner and lighter needle bars can be employed.
Figures 7 and 9 detached parts.
In Figure 6 the needle bar is entirely cylindrical and does not make the nipple
tube E turn, when it is turned by the crank handle of the machine. The upper part
of the nipple tube is provided with two flat faces q which are fitted into two pro-
longations p of the hub of pinion R and when the latter is turned by the crank handle
turns the nipple tube with it.
In Figure 8 the central tube is represented with a nipple tube which does not turn
with the crank handle as may be employed in machines which make the plain cording
work out of two threads only.
It is evident that on any of these arrangements a spool K may be employed also
which does not turn on the central tube but which may turn on a spool pin f which
is secured to plate L fig. 6 and several spools may be employed on the plate L'with
a variety of different colored threads to produce various effects.
t
As tension a weight may be employed which turns upon a fixed stud s fig. 8 and
the pressure of which may be adjusted by means of a counterweight such as a screw
nut y.
Instead of a weight an adjustable spring may he employed upon spool K, said
spring being fixed upon a support on stud s.
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 :-
1. In a sewing and embroidering machine, the combination, with stitch-forming
devices and a rotating thread-carrier for winding a second thread around the needle
thread, of a spool for said second thread, and a pinion carrying the thread-carrier
and having an opening or passage for the thread from said spool to said thread
carrier, substantially as described.
2. In a sewing and embroidering machine of the character described, a nipple tube
in two parts rigidly fastened together by a detachable connection, substantially as
set forth.
3. The combination, with stitch-forming devices and means for winding a second
thread around the sewing thread, of a nipple tube in two detachable parts, and a
spool for supplying the winding-thread, said spool surrounding one part of said tube,
substantially as described.
