PROVISIONAL SPECIFICATION.
Improvements in Embroidering and Edging Machines.
We, EMILE CORNELY and ROBERT CORNELY, both of 87, Faubourg St. Denis,
Paris, in the French Republic, Manufacturers of Sewing Machines, do hereby
declare the nature of this invention to be as follows:-
The improvements hereafter described relate to the machine described in our
Specification No. 9848 of May 8th 1896, "Improvements in embroidering and
edging machines," and more particularly to the means of operating the thread
carriers F and G when they perform an oscillating motion around their needles.
In addition, we have also modified and improved the shape of the opened nipples C
and D, as hereafter described.
When the thread carriers F and G have an oscillating motion around their
needles, the stroke of this oscillation must be of about an entire circle around
the needle. Experience has shewn that the means described in the Specification
to Letters Patent No. 9848 of 1896 aforesaid, for driving the upper thread carrier
were too heavy when the machine was to be driven at high speed, and we have
therefore designed and combined a new mechanism which drives the thread
carrier F in the same manner, but allows at the same time the machine to be
driven at high speed; we have effected this in the following manner; -
The cam secured upon main shaft N drives, in the same manner as described
in Patent No. 9848 of 1896, the lever Z, a stud of which projects into collar 30
of sleeve 31 which thus receives a horizontal to and fro motion upon hollow shaft 32
(Figures 1 and 2).
Sleeve 31 is provided with a screw nut 33 (Fig. 2) which nut by following the
to and fro motion of sleeve 31 imparts an oscillating motion to screw 34. The
shaft of this latter is guided at one end in the casting 35 of the machine and at the
other end in the hollow shaft 32 (Fig. 2); this latter hollow shaft is itself guided
in the casting 36 of the machine.
The screw 34 transmits its oscillating motion to the bevel wheels 37 and 38
and to tube 39 upon which the thread carrier F is secured.
Whilst the thread carrier F performs its oscillating motion around the needle,
said thread carrier must at the same time be governable by the crank handle of
the machine. This is obtained in the following manner;
The turning motion of the crank handle X (Fig. 1) is transmitted in the well
known manner to shaft 40 which operates hollow shaft 32 by means of bevel
wheels 41 and 42; upon this hollow shaft 32 is secured a nut or collar 43 which
slides in a corresponding slot of sleeve 31 and transmits to the latter sleeve the
turning motion of shaft 32. Sleeve 31 transmits its turning motion to screw
nut 33, screw 34, bevel wheels 37 and 38 and tube 39 upon which the thread
carrier is secured.
The motion of the under thread carrier G is obtained from main shaft N which
operates the under main shaft 49 by means of wheels 43. 44. 45 shaft 46 and

page_text: wheels 47 and 48. This shaft is provided with a cam 50 which communicates
a backward and forward motion to lever 51, shaft 52 and worm 16; this worm
transmits an oscillating motion to worm wheel 17 and tooth wheels 18 and 20
upon which latter wheel the thread carrier G is secured. In consequence of this
arrangement the motion of the under thread carrier is entirely independent of the
motion of the upper thread carrier, which is of great importance for the regulating
and timing of the machine.
As this machine works without needlé plate and the cloth being therefore only
maintained by the pressure of the two nipples C and D against the other whilst
the needles A and B (Figures 3 and 4) pierce the cloth, these two needles have a
tendency to push the cloth in their respective directions, which is a great hin-
drance when the machine is driven at high speed.
In order to obviate this inconvenience, we have provided the nipples C and D
with a kind of shield or curved horn 53 and 54 which partly encloses the needles
Figures 3 and 4, and which press upon the cloth whilst it is traversed by the needles
so that the above mentioned inconveniences are entirely obviated.
The section across nipples C and D and their respective positions to each other
is represented at Figure 4, in which the upper nipple C is shown in full lines
and the under nipple D in dotted lines.
When the edging or embroidering seam is to be provided with a filling in
order to obtain a thicker or higher effect, said filling thread 53* (Figures 1 and 2)
comes through central tube 54* whence it passes out through opening 55; it
then traverses the opening 56 of tube 39 which supports the thread carrier F;
thence it comes through a passage arranged in the side of tube 60 which revolves
in the casting of the machine; it comes out from this passage at opening 61 and
goes finally through the guide 63 which is near the under end of nipple C. The
guide 63 of the filling 53* is governable from the crank handle X of the machine
by means of tooth wheel 64 which is secured upon tube 60, by means of tooth
wheels 65, 66 and 67, see Figure 1.
The thread of the thread carrier F passes also through the central tube of the
machine whence it comes out through an opening of nipple C and from there it
passes through the guide of thread carrier F.
On the accompanying drawings, Figure 1 is a side elevation of the machine, and
Figure 2 is a sectional elevation of a portion of the mechanism; Figure 3 is an
elevation of the nipples and thread carriers, whilst Figure 4 is a plan view of the
upper nipple.
Improvements in Embroidering and Edging Machines
We, EMILE CORNELY and ROBERT CORNELY, both of 87, Faubourg St. Denis,
Paris, in the French Republic, Manufacturers of Sewing Machines, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
:-
The improvements hereafter described relate to the machine described in our
Specification No. 9848 of May 8th 1896, "Improvements in embroidering and

page_text: edging machines," and more particularly to the means of operating the thread
carriers F and G when they perform an oscillating motion around their needles.
In addition, we have also modified and improved the shape of the opened nipples C
and D, as hereafter described.
When the thread carriers F and G have an oscillating motion around their
needles, the stroke of this oscillation must be of about an entire circle around
the needle. Experience has shewn that the means described in the Specification
to Letters Patent No. 9848 of 1896 aforesaid, for driving the upper thread carrier F
were too heavy when the machine was to be driven at high speed, and we have
therefore designed and combined a new mechanism which drives the thread
carrier Fin the same manner, but allows at the same time the machine to be
driven at high speed; we have effected this in the following manner;-
The cam secured upon main shaft N drives, in the same manner as described
in Patent No. 9848 of 1896, the lever Z, a stud of which projects into collar 30
of sleeve 31 which thus receives a horizontal to and fro motion upon hollow shaft 32
(Figures 1 and 2 of the annexed drawings).
Sleeve 31 is provided with a screw nut 33 (Fig. 2) which nut by following the
to and fro motion of sleeve 31 imparts an oscillating motion to screw 34. The
shaft of this latter is guided at one end in the casting 35 of the machine and at the
other end in the hollow shaft 32 (Fig. 2); this latter hollow shaft is itself guided
in the casting 36 of the machine.
The screw 34 transmits its oscillating motion to the bevel wheels 37 and 38
and to tube 39 upon which the thread carrier F is secured.
Whilst the thread carrier F performs its oscillating motion around the needle,
said thread carrier must at the same time be governable by the crank handle of
the machine. This is obtained in the following manner;
The turning motion of the crank-handle X (Fig. 1) is transmitted in the well
known manner to shaft 40 which operates hollow shaft 32 by means of bevel
wheels 41 and 42; upon this hollow shaft 32 is secured a nut or collar 43 which
slides in a corresponding slot of sleeve 31 and transmits to the latter sleeve the
turning motion of shaft 32. Sleeve 31 transmits its turning motion to screw
nut 33, screw 34, bevel wheels 37 and 38 and tube 39 upon which the thread
carrier F is secured.
The motion of the under thread carrier G is obtained from main shaft N which
operates the under main shaft 49 by means of wheels 43, 44, 45, shaft 46 and
wheels 47 and 48. This shaft is provided with a cam 50 which communicates
a backward and forward motion to lever 51, shaft 52 and worm 16; this worm
transmits an oscillating motion to worm wheel 17 and tooth wheels 18 and 20
upon which latter wheel the thread carrier G is secured. In consequence of this
arrangement the motion of the under thread carrier is entirely independent of the
mation of the upper thread carrier, which is of great importance for the regulating
and timing of the machine.
Since this machine works without needle plate and the cloth being therefore only
maintained by the pressure of the two nipples C and D against each other whilst
the needles A and B (Figures 3 and 4) pierce the cloth, these two needles have a
tendency to push the cloth in their respective directions, which is a great
hindrance when the machine is driven at high speed.
In order to obviate this inconvenience, we have provided the nipples C and D
with a kind of shield or curved horn 53 and 54 which partly encloses the needles
(Figures 3 and 4), and which press upon the cloth whilst it is traversed by the
needles so that the above mentioned inconveniences are entirely obviated.
The section across nipples C and D and their respective positions to each other
are represented on Figure 4, in which the upper nipple C is shown in full lines
and the under nipple D in dotted lines.
When the edging or embroidering seam is to be provided with a filling in
order to obtain a thicker or higher effect, said filling thread 53 (Figures 1 and 2)
comes through central tube 54* whence it passes out through opening 55; it

page_text: then traverses the opening 56 of tube 39 which supports the thread carrier F;
thence it comes through a passage arranged in the side of tube 60 which revolves
in the casting of the machine; it comes out from this passage at opening 61 and
goes finally through the guide 63 which is near the under end of nipple C. The
guide of the filling 53 is governable from the crank handle X of the machine
by means of tooth wheel 64 which is secured upon tube 60, by means of tooth
wheels 65, 66 and 67, see Figure 1.
The thread of the thread carrier F passes also through the central tube of the
machine whence it comes out through an opening or nipple C and from there it
passes through the guide of thread carrier F.
On the annexed drawings, Figure 1 is a side elevation of the machine, and
Figure 2 is a sectional elevation of a portion of the mechanism; Figure 3 is an
elevation of the nipples and thread carriers, whilst Figure 4 is a plan view of the
upper nipple.
It is evident that the mechanism herein described for operating the upper thread
carrier can also be employed for the operation of the under thread carrier, or
rice versa.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is :-
(1). In embroidering and edging machines, the mechanism for driving the
upper oscillating thread carrier F by means of screw 34 which is guided at one
end in the casting of the machine and at the other end in the hollow shaft 32
so that the thread carrier F whilst oscillating, is still governable by the crank
handle of the machine, substantially as above described.
(2). In embroidering and edging machines, the shield or curved projections 53
and 54 of nipples C and D which partly enclose the needle and maintain the cloth
whilst it is being pierced by the needles, substantially as above described.
