PROVISIONAL SPECIFICATION.
Improved Sewing Machine for Corsets.
I, PIERRE ALEXANDER DARRACQ of Le Pré St. Gervais, in the Republic of France,
Mechanical Engineer, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to provide machinery for producing the fan like
arrangement of stitches which occurs in the manufacture of corsets, the object of
which is to secure the ends of the whalebones or "stays," and the invention consists
essentially in an arrangement or mechanism for displacing the head of the machine
for producing the longitudinal stitches and the corset in a transverso direction either
to the right or left in such a manner that the needle descends at suitable places to
produce the peculiar fan-like arrangement of stitches, instead of displacing the corset
only in both directions as in the machine described in the specification of my former
Letters Patent No. 11446 of A.D. 1887.
The corset is placed in position upon the machine and when the machine is started
the needle will make two stitches in the same place so as to lock each other and thus
form a strong beginning, the corset is then displaced transversely to make the first
stitch of the fan, the head of the machine is then displaced without moving the corset
in the least, for making the second stitch, the corset is then displaced laterally a
distance equal to the thickness of the thread for making the third stitch and the head
of the machine is again displaced for making the fourth stitch, and so on until the fan
is finished, when the corset is once more displaced transversely and a double locking
stitch made the same as at the beginning.
The machinery that I have constructed has therefore to displace the corset in one
direction and the sewing parts of the machine in another direction, moreover the
longitudinal displacements must vary constantly in length to a considerable extent the
greatest displacement being between the first two stitches and the smallest between
the last two, moreover the stitches which are parallel to the edge of the whalebone
have to be in a straight line whilst those which confine the end thereof have to be
arranged in an are of a circle or in a form corresponding with the end of the bone;
lastly the machine must stop as soon as the fan is completed.
The machine essentially comprises all parts of an ordinary sewing machine and in
addition special mechanical arrangements for the automatic movement of the corset
and the sewing parts of the machine and for the stopping of the machine when the
fan is completed.
To effect the displacements of the head of the machine a cam wheel is employed.
This cam wheel is mounted on a horizontal shaft journalled suitably in the frame of
the machine, and at its side has secured to it a bevil gear wheel engaging with a bevil
pinion mounted on a shaft which receives its movement from the driving shaft by
means of intermediate gearing.
A small roller mounted on the end of a pivotted lever runs in the groove of the
cam wheel and communicates an irregular motion to the said lever corresponding to
the sinuosity of the groove. The end of this said lever, opposite to the small roller
is connected to the lower side of the head of the machine and thus communicates a
horizontal movement to the latter. By this arrangement the head of the machine is
displaced by the revolution of the driving shaft.
The pivot of the above mentioned lever is adjustable so as to enable its stroke and
consequently the amplitude of the longitudinal stitches to be regulated according to
requirements.
To produce the transverse stitches the corset itself is moved or displaced laterally
to the right or left by means of carriers in combination with the pressor feet.

page_text: Two arms or standards of about the same contour as the head of the machine are
fixed on the top of the machine and between these arms the head of the machine
reciprocates horizontally. Each of these arms or standards is provided with a presser
foot bar and presser foot arranged to work in the usual manner. Underneath each
of these presser feet is a circular serrated carrier or feed wheel mounted on a
horizontal shaft which carries gearing to communicate movement to the said shafts.
This gearing is operated through intermediate gearing from the driving shaft and
turns the carriers or feed wheels to the right or left under the influence of a pivotted
lever according to whether the corset is to be displaced to the right or the left. The
relative position of two slotted rods fastened together by a screw to form one rod of
the intermediate gearing permits the adjustment of the movement of the carriers or
feed wheels so as to produce longer or shorter transverse stitches.
The machine is stopped automatically when the fan is finished, by the following
arrangement:
A laterally projecting rod fixed to the before mentioned cam wheel which hori-
zontally displaces the head of the machine comes, after one revolution of said cam
wheel e. when the fan is finished, in contact with a pivotted lever operating a fork
which releases a clutch and thus instantly causes the machine to stop.

COMPLETE SPECIFICATION.
Improved Sewing Machine for Corsets.
I, PIERRE ALEXANDER DARRACQ of Le Pré St. Gervais, in the Republic of France
Mechanical Engineer, 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 :-
The object of this invention is to provide a machine for producing the fanlike
arrangement of stitches which occurs in the manufacture of corsets, the object of
which is to secure the ends of the whalebones or "stays," and the invention consists
essentially in an arrangement or mechanism for displacing the head of the machine
for producing the longitudinal stitches, and the corset in a transverse direction either
to the right or to the left in such a manner that the needle descends at suitable places
to produce the peculiar fanlike arrangement of stitches instead of displacing the
corset only in both directions.

stay" confined by
The corset is placed in position on the machine and when the machine is started the
needle will make two stitches 0, 00 in the same place so as to lock each other and

page_text: thus form a strong beginning, the corset is then displaced transversely to make
stitch 1 of the fan, after this the head of the machine is displaced without moving
the corset for making stitch No. 2, the corset is then displaced laterally a distance
equal to the thickness of the thread and the sewing mechanism correspondingly in
the longitudinal sense for making stitch 3, the head of the machine is then displaced
again for making stitch 4, and so on until the fan is finished, when the corset is once
more displaced laterally to make a double interlocking stitch 25, 26 the same as was
made at the beginning.
The machinery that I have constructed has therefore to displace the corset in one
direction and the sewing parts of the machine in another direction, moreover the
longitudinal displacement must vary constantly in length to a considerable extent; the
greatest displacement being between the first two stitches of the fan and the smallest
between the last two stitches, moreover the stitches which are parallel to the edge of
the whalebone or stay have to be in a straight line, whilst those confining the end of
the whalebone or stay have to be arranged in the arc of a circle or in a form
corresponding with the said end; lastly, the machine is to stop automatically as soon
as the fan is completed.
The machine comprises essentially all parts of an ordinary sewing machine and in
addition special mechanical arrangements for the automatic displacement of the corset
and the sewing parts of the machine and for the stopping of the machine when the
fan is completed.
The horizontal displacement of the head A of the machine is effected by means of
a camwheel S which also regulates the amplitude of the stitches.
To this end the head A of the machine oscillates horizontally between the
centres a¹ a¹ of a vertical stirrup piece B fixed to the frame between the vertical
sides of which are mounted all the various parts of the mechanisın.
The shaft D which operates the sewing parts of the machine is by means of a link
and two knuckle joints M M or the equivalents thereof attached to the shaft L from
which it receives its movement, thus permitting the shaft D to follow the horizontal
displacement of the head of the machine.
On the shaft L is mounted a pitch wheel N receiving its motion from a pitch chain;
this wheel N is mounted loosely but can be engaged with and transmit motion to the
shaft L by means of the clutch coupling O which is capable of being moved longi-
tudinally on the shaft L but always turns with it. A spiral spring P interposed
between the clutch coupling and a collar Qon the shaft L tends to hold the coupling O
in engagement with the clutch face of the wheel N. The shaft L is mounted in the
journals R R forming part of the frame C of the machine.
The horizontal displacement of the head of the machine is produced by means of
the camwheel S the cam-groove of which is represented in projection or developed
view in Fig. 5. The horizontal shaft U of tho said cam wheel is supported in a
downwardly projecting arm V of the frame of the machine.
The cam wheel S carries on its face a bevil wheel V1 gearing with the bevil
pinion V to which motion is transmitted from the shaft L by means of the mitro
wheel X fixed on the shaft L and gearing with the mitre wheel X¹ mounted on the
shaft L the bevil wheel X" mounted on the same shaft and gearing with a bevil
wheel mounted on the shaft L which carries at its lower end the pinion VII.
A roller 1 mounted on the end of a lover 2 the pivot 3 of which is adjustable, is
guided in the cam-groove 4 of the cam wheel S the sinuosities of which cam groove
correspond with the desired displacements of the head of the machine. The pivot 3
of the lever 2 can be placed in either of the two holes 31 formed in the base of the
stirrup piece B. The end of the lever 2 opposite to that carrying the roller 1 being
attached to the bottom part 5 of the head of the machine the horizontal movements
of the roller 1 following the sinuosities of the cam groove 4 are transmitted to the
head of the machine.
Thus it will be seen that the so-called longitudinal stitches are regulated by the
revolution of the cam wheel S without the corset itself being moved in any way. To
produce the so-called transverse stitches of the fan the corset itself is displaced in a

page_text: transverse senso under the influence of carriers or feed wheels arranged underneath
the presser feet.
Two arms or standards 6 6' of about the same contour as the head of the machino
are fixed to the top of the stirrup piece B and between these arms the head of the
machine reciprocates horizontally. Each of the arms or standards 6 6' is provided
with a presser foot bar and presser foot 7 71 arranged to work in the usual manner.
Underneath each of these presser feet 7 7' is a circular serrated carrier or feed
wheel 8 8 mounted respectively on the shafts 9 91 which transmit their movement to
the wheels 8 81 for the displacement of the corset in a sense transverse to the fan to
be formed.
To this end the gear wheels 10 10' are secured on the shafts 99¹ and receive their
movement from the corresponding gearwheels 11 11' fixed on the shaft 12 journalled
in the supports 13 13' mounted on the shafts 9 9.
On each side of the gear wheel 11 one of the supports 14 14' is mounted on the
shaft 12; these supports carry at their lower ends a shaft 15 on which is mounted
loosely a gear wheel 16 in the same vertical plane as with the wheels 10 and 11; the
shaft 15 is attached to a lever 17 pivotted at 18 and adapted to be adjusted to two
different positions by means of the spring button 19 which it carries at its end and
which may be engaged with either of the openings 20 or 21 formed in the
indicator 22.
Movement is transmitted to the wheels 10, 11, 16 by means of a pinion 23 mounted
on a shaft 24 journalled in one side of the frame and a support 25 attached to the
said frame.
As represented in Fig. 2 the pinion 23 operates the wheel 10 through the wheel 11
which is always in gear with the wheel LG which in this case turns loosely on its
shaft. It follows therefore that when the pinion 23 turns in the direction of the
arrow 26, the wheel 11 turns in the direction of the arrow 26' and the wheel 10 in
that of the arrow 26 that is towards the left. The lever 17 is in this Fig. 2 repre-
sented as having its spring button 19 in the opening 20 of the indicator 22, if tho
lever 17 be turned on its pivot 18 so that the spring button 19 would engage with the
opening 21 of the indicator 22 it would follow by the arrangement of the supports
and lever 13, 14, 17 that the angle formed by the supports 13 14 would become more
acute, while that formed by the support 14 and lever 17 would become more obtuse
and consequently the wheel 11, although always gearing with the wheels 10 and 16
would be thrown out of gear with the pinion 23, while the wheels 16 would be thrown
into gear therewith and thus would transmit motion to the wheel 10 by means of the
wheel 11. The wheel 10 would therefore turn in the opposite direction because the
rotation of the pinion 23 being always in the direction of the arrow 26 the wheel 16
will turn in the direction of the arrow 27, the wheel 11 in that of the arrow 27¹ and
10 in that of 27". The two wheels 11 11' being both secured on the same shaft 12
their movement will be transmitted to the wheels 10 10¹ and through these to the
feed wheels or carriers 8 8'.
From the preceding explanation it will be understood that the feed wheels 8 8' can
be made to revolvo to the right or the left according to the desired displacement of
the corset to the right or the left by the adjustment of the pivotted lever 17.
The pinion 23 receives its motion in the following manner: on the shaft 21 of this
pinion 23 is mounted a disc 28 formed on its face with a recess 29 in the interior of
which engages a sector 30 operating by friction on the wall of said recess. This
sector is mounted loosely on the eccentric socket 30' of the lever 31 pivotted on the
shaft. 24. This lever is connected to the lever 32 by means of slots, and bolt, and
nut 36 the lever 32 being pivotted to the side of the frame at 33. The oscillation of
the lever 32 is produced by means of a cam wheel 34, the cam groove of which
operates on a roller 35 carried on the said lever. The two levers 31 32 are adjustable
as regards their length by means of the bolt and nut 36. The oscillation of the
lever 32 produced by means of the cam 34 is transmitted to the lever 31 which by
means of the eccentric socket 301 and the sector 30) operates the disc 28. The moving
of the sector 30 is effected as follows:-the lever 31 moving from its lower to its

page_text: higher position forces the sector 30, by means of the eccentric socket 30' against
the outer wall of the recess 29 of the disc 28, the upward movement of the lever 31
continuing, the sector 30 will in consequence of the eccentricity of the socket 30¹
force the disc 28 to turn from right to left and this rotary movement will continue
until the lever 31 has attained its highest point; during the downward movement of
the said lever the sector is drawn back by a suitable spring 29' until the next upward
movement of the lever commences. The movement of the disc 25 is regulated by a
suitable brake 28¹.
The manner of adjusting the combined length of the levers 31 32 by means of tho
bolt and nut 36 permits of the amplitude of the oscillation of the lever 31 being
regulated, and consequently provides for the necessary regulation of the rotary
movement of the disc 28 and that of the feed wheels 8 8' by means of the above
described intermediate gearing.
The can 34 is mounted on the shaft 36' on which is also mounted a bevil wheel 37
gearing with a bevil pinion 38 mounted on an inclined shaft 39 carrying at its other
end the bevil pinion 40 gearing with the hevil pinion 41 mounted on the shaft L'
which receives its rotary motion as before described.
It has herein been previously explained that as soon as the last double stitch 25-26
of the fan has been made the machine stops automatically; this automatic stopping
is effected by the following arrangement; The principal camwheel S is provided with
a spring button S¹ to which is fixed a pin S" which when the cainwheel has completed
its revolution i.e. when the fan is finished, comes in contact with the end of a lever T
pivotted at T and extending above this pivot. This upward extension of the lever T'
bears against an arm U¹ mounted on the shaft U which carries the uncoupling
fork V which turning with the said shaft from right to left immediately disengages
the clutch sleeve O from the wheel N and instantly stops the machine.
To start the machine again it is only necessary to draw forward the pin S₁ by the
spring button S¹ when the said pin ceasing to bear against the lever Tis (the lever T¹)
will immediately return to its normal position under the influence of the spring P
which also again throws the coupling sleeve O into engagement with the clutch face
on the wheel N thus turning the fork V with the shaft U" and the arm U' which
latter returns the lever T¹ to its normal position.
This operation of starting the machine instead of being done by drawing the spring
button S forward by hand, may be done by a simple movement of the knee, which
arrangement is represented in Fig. 8 and has the advantage of leaving the hands
entirely free for the maintaining and guiding of the corset on the machine. This
arrangement consists of a lever 50 pivotted at about its middle at 51 to a bracket or
projection 52 on the frame of the machine. One end 50¹ of this lever is bent
inwards toward the camwheel S the extreme end of it standing exactly opposite the
pin S where the latter has pressed the lever T' aside and thus stopped the machine.
The other end of the lever 50 is pivotted to a bell crank lever 53, 54 pivotted at 55 to
a bracket or projection on the frame C of the machine. The arm 54 of the bell
crank extends to the front of the machine where it is provided with a plate 56 against
which the knee of the operator is pressed when it is desired to start the machine.
A suitable spring 57 returns the lever 54 to its normal position.
It is evident that a pressure on the plate 56 will have the same effect as the
drawing forward by band of the spring button S₁ as the end 50' of the lever 50 will
push the pin S" as soon as the lever 4 is pressed aside by the knee of the operator.
The shuttle carrier E which acts in combination with the needle K is operated by
the shaft D and receives a differential intermittent movement with reference to the
said shaft D. The object of this differential intermittent movement is to seize the
needle thread sharply and to pass it rapidly round the shuttle and then to give time
to the needle and to the tension device to draw the thread and to displace themselves
in the longitudinal sense for the next longitudinal stitch. To this end the shuttle
carrier E is mounted on a small spinelle E journalled in a support E". The said
spindle E extends beyond the support E" and carries on its extreme end a pinion F".
On the forward end of the shaft Dis mounted a disc F formed with a recess in its

page_text: face part of the wall G' of which recess is provided with teeth G" which gearing
with the pinion F' extending into the recess turns this pinion and with it the shuttle
carrier E.
The rotary movement of the pinion F' of course ceases as soon as the last tooth of
the sector Ghas passed it and the said pinion remains stationary until the teeth
engage again with it during the next revolution of the disc F".
The feeding of the thread as in the ordinary machines, is effected by means of the
tension device H H" the latter being operated by the cam wheel H mounted on the
shaft D.
With the intention of allowing a greater variation in the amplitude of the oscillatory
movement of the lever 2 and consequently a greater variation of the dimensions of
the longitudinal points of the fan the pivot 3 of the lever 2 is placed on a carriage 70)
whence the longitudinal movement according to requirements by help of the scrow 71
is controlled from the exterior of the machine by means of the screw and worm
wheel 72, 73.
With the view of permitting a greater variation in the cam wheels S which may be
used on the machine the shaft U of the said cam wheels is mounted in the carriage 74
in such a way as to be capable of occupying in height all the desired positions
according to the diameter of the cam wheels S employed.
For producing the fan whether to the right or to the left the movement of the
corset can always be effected in the same direction in which case the direction of the
working of the fan will depend on the direction of rotation of the cam wheel S; this
result is obtained by means of the following arrangement. On the shaft L a sleeve 75
will be fixed having a little pinion 76 76 at each extremity the throwing of one of
these pinions into gear with the wheel X' transmitting motion to the cams S and to
the feed wheels 8 8 will be produced by means of the forked lever 77 pivotted on a
fixed point 78; the throwing into gear respectively of the pinions 76 76' with the
pinion X, will be determined by the position of the lever 77 at one of the
positions 79 79¹ of the framework.
The shaft L turning always in the same direction according as one of the
pinions 76 76' engages with the pinion X this latter and consequently the cam
wheel S will turn either one way or the other and will operate the lever 2 by
beginning with the little longitudinal points of the fan if the rotation is made in ono
way, or by beginning with the large longitudinal points if the rotation of the cam
wheel S takes place in a contrary direction; by these means in order to obtain the
working of the fan either to the right or left. the rotary movement of the feed
wheels 8 8 will be effected in the same direction. The displacement of the corset
being effected in the same manner, and consequently the order of this rotatory
movement can be considerably simplified by the adoption of the following arrange-
ments. Inside of the feed wheels 8 8¹ and on the same shafts 9 9' two sets of
gear 80 80 will be fixed which will be respectively thrown into gear with two other
sets of gear wheels 81 81' fixed on the same shaft 24 bearing the friction operated
disc 28. In front of this disc 28 on the same axis 24 a lever 82 is carried which by
its oscillation will cause the disc 28 to move, and in consequence thereof also move
the feedwheels 8 8'; the oscillation of this lever is produced by a cam 83 fixed to
the shaft 36 which controls the gears 37 and 38 &c., as before. The set screw 84
serves to regulate the amplitude of the rotatory movement of the feed wheels 8 81
and of the transverse displacements of the corset. A spring 85 serves to draw back
the lever 82 to its normal position.
The operation of the needle can be effected by means of an oscillating lever 86
attached at one end by a double joint or link 87 to the needle bar J. and at the other
end by the joint 87' to a vertical rod 88 which is moved vertically by a cam 89 the
point 90 being the pivot of the oscillating lever 86.
The raising and lowering of the presser feet 7 7' can be effected by means of the
fore arm which resting on the socket 91 of a bent rod 92 will move the connections
and levers 93, 94, 95, 96, 97 the latter carrying a pin abutting on the crank lever 98
for raising or lowering the presser feet; this arrangement leaves the bands perfectly

page_text: free to support the corset on the machine. In order to make the working of the
points of the fan more certain there is provided a kind of rest 100 which may be
termed a thread regulator, its aim really being in working with the needle holder to
prevent the thread twisting; for this purpose it is attached to the head of the machine
by an oscillating lever 101 which accompanies it in its descent and compels it to
oscillate at the same moment that the needle is going to enter the fabric in such a
way as to carry the well extended thread towards the place where it is to penetrate;
the slight oscillatory movement of the thread-regulator 100 is effected by the cam
groove 103 through which passes the pin 104. This latter moreover having for its
object while pressing on the fabric with its base 105 in the shape of a rest and
crossed by the needle to properly maintain the fabric on the work plate whilst the loop
forms itself which prevents the marks of the needle showing.
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;

the whole arrangement being such that if the fan is to be produced to the right and
the feedwheels 8 8¹ consequently must turn to the left to displace the corset in that
direction, the spring button 19 is placed in the opening 20, and in consequence of the
position of the levers 17, 14 and 13 relative to each other, the wheel 11 will gear
with the pinion 23 and transmits the movement to the feed wheels 8 8' by the
wheels 10 10 or if the fan is to be produced to the left, the spring button 19 is
placed in the opening 21, when by the position of the levers 17, 14, 13 the wheel 16
will gear with the pinion 23 while the wheel 11 is thrown out of gear with the
pinion 23 but still gearing with the wheels 10 and 16 the movement of the pinion 23
which does not change its direction is transmitted to the feed wheels 8 8¹ by means of
the wheels 16, 11 and 10 thus turning the said feed wheels in the opposite direction
substantially as herein described and illustrated in the accompanying drawings.
