Improvements in Apparatus for Punching Jacquard Patterns,
chiefly applicable for Perforating Jacquard Patterns for
Embroidering Machines.
I, JOSHUA ENTWISLE, of the Firm of E. K. Dutton & Co., of 5, John Dalton Street,
Manchester, in the County of Lancaster, Fellow of the Chartered Institute of Patent
Agents, do hereby declare the nature of this invention (a communication to me
by The Kursheedt Manufacturing Company, (Incorporated under the Laws of the
State of New York), of 356 to 360, West Broadway, New York City, United States of
America, Manufacturers), and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement and
accompanying drawings:-
The herein described invention refers to a punching machine for Jacquard patterns,
more particularly for perforating Jacquard patterns for embroidering machines, and
is combined with a control embroidering machine which enables the operator to see
at all times whether the Jacquard pattern has been perforated correctly or. not.
The drawings represent one form of this machine.
Figs. 1 and 2 are front and rear elevation some parts of the mechanism being
omitted.
Fig. 3 is a section on line U U, and Fig. 4 is a section on line V V of Fig. 2.
Figs. 5 and 6 are details of Figs. 1 and 2.
The other views are on a larger scale.
Fig. 7 is a horizontal section on line W W of Fig. 1.
Fig. 8 is a front view of the lower central part of the machine.
Fig. 9 is a sectional view on line X X of Fig. 8.
Figs. 10 and 11 are sectional views on lines Y Y and Z Z of Fig. 8.
Fig. 12 is a sectional view on line T T of Fig. 3.
Figs. 13 to 58 represent various parts of the machine.
Between the uprights A of the frame of the machine are transverse bars a to which
are secured the perpendicular bars a¹ a¹, between which a board a2 is guided and is
adjustable in a perpendicular direction.
A design can be secured to the front surface of the board from which a perforated
Jacquard pattern is to be punched. This board a² is shown in its lowest position in
Figs. 1 and 2. To the back of this board near its lower end, is secured a stud a³,
which is connected by means of a link a with a crank a5, the latter is secured to the
end of a rotatable shaft 6 to the other end of which is secured a hand lever a².
The one arm of this lever is provided with a handle, while the other arm is provided
with an adjusting screw. By means of this lever a the shaft a can be rotated about
180 degrees in the direction of the arrow (Fig. 2) and thereby the board a² can be
raised. The adjusting screw on the hand lever a by abutting against the upright A
limits the rotation. In front of the board a² are two rectangles B and B¹ which are
arranged to slide perpendicularly and are guided by ways b³ on the uprights A see
Fig. 7 the opposite sides of the rectangles are guided in grooves b*.
The rectangle B is provided with a diagonal bar from the upper left hand corner to
the lower right hand corner, while the rectangle B is provided with a diagonal bar

page_text: from the upper right hand corner to the lower left hand corner. These diagonal
bars are arranged to cross at an angle of 90 degrees. On the upper edges of these
two diagonal bars rests a slide 67 (Figs. 1, 14 and 15), the lower end of which rests by
means of a button 610 on the surface of the diagonal bar be. The slide 67 is provided
with a sight 61, movement of the one or the other or both of the rectangles B
and B will displace the slide 67 and bring the sight 611 to any desired point on the
surface of the design.
To the guides 6 and 6' of the rectangles B and B₁ are fastened steel bands 613 614
which are carried over pullies 15 and 66 to the rear of the machine, and are there
secured to weights 617 which balance the rectangles (Figs. 1, 2 and 4). Between the
lower ends of the weights and the lower steel band 64 are springs bls, which serve to
maintain an equal tension on the steel bands 613 614. Secured to the shafts of the
lower pullies 66 are gear wheels 619. The pinions 621 by means of intermediate
gears 620 are in mesh with the gear wheels 610. Each pinion 621 is secured to a
disc c¹. Similar discs c² are mounted loosely on studs secured to the upper ends of
the bars a', and endless cords c³ are carried over the upper and lower discs. By
means of these cords the discs c¹, and by means of the gearing above described the
corresponding pullies 616 can be turned by hand in the one or other direction. In
this manner each of the rectangles B or B¹ can be moved along its ways up or down.
One of the discs c¹ with its pinion 621 is secured to a shaft C¹, the one end of which
is made tubular and receives the end of the shaft C Fig. 16.
A sleeve c is loose on the shaft C and the other disc c¹ with its pinion is loose
on the sleeve. The ends of the shaft C and the sleeve c extend outside of the
upright A, and are provided at their ends with the pinions c³ and c respectively.
The pinion c3 by means of intermediate gears and pinions c5, c and c', is in mesh
with the vertical rack c³ (see Fig. 3) while the pinion c4 by means of intermediate
gears and pinions c c and c² is in mesh with the second vertical rack c³. The upper
end of the rack c8 is fastened to a frame co while the upper end of the rack c is
fastened to a frame c¹¹. These frames (Figs. 1, 2, 3, 5, 6 and 12) are arranged to
slide vertically in ways c¹² and c¹³ secured to the upright A and each is provided with
two inclined parallel grooves c¹. The frames c10 and c¹ are arranged so that the
inclined grooves are placed opposite each other and cross at an angle of
90 degrees.
The ends of the upper and lower transverse bars c¹ and c¹7 of the fabric frame Co
of the control embroidering machine, are provided with projections c¹5 which
enter the grooves of the frames c¹0 and c¹¹.
Fastened to the upper ends of the frames c¹0 and c¹¹ are the ends of the a
belt cs which passes over a pulley c¹ the latter being mounted loosely in a
hanger attached to one end of a second belt c20. The belt c20 is carried over
a pulley which is mounted loosely near the upper end of the upright A. To the
other end of this belt c20 is attached a weight 22, which balances the weight of
the frames c¹0 and c¹ and of the fabric frame Co. When the rectangles are
being moved up or down along their ways by means of the cords, the frames
c10 and cl move in harmony, and by their combined action move the fabric frame
to the desired point. The gearing is so arranged that the displacement of the
frames co and c¹¹ is one-sixth of that of the rectangles.
The movement of the rectangles B and B is by means of the connections already
described and by means of the gear wheels 23 23 on the shaft C and sleeve
transmitted to the mechanism which determines the required perforations in the
jacquard pattern. The gear wheel c23 is secured to the shaft C and is by means of a
bolt c24 connected to coupling c25 on the shaft C¹. The head of the bolt c²+ enters
into a groove c² on collar 27 see Fig. 8 so that by sliding this collar on the shaft C¹
the gear wheel c23 can be disconnected from or connected to the coupling 25. The
other gear wheel is secured to the sleeve c and the corresponding disc c' is loose
on the same sleeve.
A bolt 2 whose head fits into a groove c20 of another collar c²7
is in the coupling 25 which is secured to the sleeve c. The two collars 27 are pro-
vided with arms and secured to a common rod c29, which is provided with a handle c³0

page_text: by which means both collars can be shifted at the same time in the one or in the
other direction.
To the foundation plate D which is held between the two uprights A are secured
side frames d d. To each of these side frames is secured a bearing d¹ d2 and between
these two bearings are placed four pin wheels e¹ e2e3e (Figs. 1, 8, 9, 16, 17, 18
and 19) The circumference of these pin wheels is divided into fifteen parts,
fourteen out of the fifteen divisions are provided each with a projecting pin e while
one division remains vacant.
The pins e are arranged in spirals running on one half of the circumference from
one end to the other and on the other half of the circumference back again. One
end (right) of each pin wheel is provided with a flange e extending over seven
divisions and which is of the same height as the pins.
The pin wheels e2 e3 are secured to shafts 3 and respectively while the pin
wheels e¹ and e' are secured to sleeves and mounted loosely on the shafts d³
and d (Fig. 16). The shaft d³ also carries loosely a pinion d' which is provided with
a disc d.
A similar pinion d with disc d8 is loosely mounted on the sleeve (6.
Each of these pinions is in mesh with a corresponding gear wheel 23 and is rotated
whenever the discs c¹ (by means of the cords) are turned in the one or the other
direction. The discs ds of the pinions d' are provided near their circumference with
fifteen holes do at regular distances from one another Fig. 20. A bolt 12 in the
double disc d¹ and d which is secured to the shaft d³ or to the sleeve d', is arranged
to enter any one of these holes. The discs d¹0 are provided with a stud d¹ which at
each revolution engages with one of the four slots d¹ (Figs. 22 and 22^) of a wheel d¹
and rotates the latter one quarter turn.
Each of these wheels 17 is secured to a shaft d18 which carries another wheel d¹⁹.
The circumference of the wheel d¹ is made to fit after each quarter turn on the
circumference of disc d¹, and prevents any accidental rotation of the shaft d18.
The disc d has diametrically opposite the bolt d¹² a notch d which permits the
wheels d, d on the shaft d¹s to turn a quarter turn after every rotation of the
discs 10 and 11. The rotation of the shafts 18 is transmitted to the sleeve №5 or
the shaft d by means of the wheels 21 which are provided with four studs, which.
latter are arranged to enter spaces in the wheels 22
·
The wheels (722 are loose on the sleeve 5 or on the shaft and are connected
by means of bolts 23 with discs d2, which are provided with corresponding holes to
receive the bolts (Fig. 23) and are secured to the sleeve d or to the shaft d. The
heads of the bolts d¹2 23 enter in grooves in four collars d25 and d26 which are provided
with arms and secured to a rod d, which can be shifted in the direction of its axis.
By shifting this rod d¹³, the bolts d and d³ can be withdrawn from the holes in the
discs d8 and 24, so that the pin wheels e¹ e² e³ and e' can be turned to their normal
positions. For this purpose the discs d" and 24 are provided with noses d³ and d³7
(Figs. 16, 22, 22, 23) and tongs f f are provided, adapted to engage with the two
oppositely placed noses, (Figs. 8, 24, 25 and 26). The lower ends of the tongs are
pivotted to a lever f¹ secured to a rock shaft F. The tongs by means of the links f
are also pivotted to the brackets d¹ d².
The upper ends of these tongs are fork-shaped and are in their normal position,
shown in Fig. 25 above the noses d³ d.
During the downward motion one or the other side of the tongs f f engages with
the noses and brings thein back to their normal positions as shown in Figs. 16, 22,
23, so that the vacant division of the pin wheels brought to the top.
It will be understood from the above description that the pin wheels are set to
their proper position by hand, while the punching of the holes in the Jacquard
pattern is done by mechanical means. A pulley G (Figs. 2, 27 and 28) is rotatively
imounted in a bearing G which is fastened to the foundation plate D.
The pulley G is arranged to engage with the friction clutch G¹, which is secured
on a shaft G2, the latter being rotatably mounted in the bearing Go, and is besides
capable of being moved in the direction of its axis. G³.is a brake ring on the
bearing Go. To the shaft G2 are secured a collar g¹ and a pinion g². The drawing

page_text: shows the shaft in position when the machine is at rest, and in this position the
arm g³ of a bell crank lever g³ g4 bears against the collar g¹ and forces the friction
clutch G away from the driving pulley G and against the brake ring G³, so that the
driving pulley will rotate idly.
The bell crank lever g³g is held in this position by a shoulder g' on the two armed
lever g³ g bearing against a shoulder gs of the arm g'. When the lever g³, go is
moved so as to disengage its shoulder 77 from the shoulder gs of the lever g', then
under the action of a spring g', the shaft. G is pushed in the direction of the
arrow 910 (Fig. 28) so that the friction clutch G¹ leaves the brake ring G³ and engages
with the driving pulley G whereby the shaft G2 is rotated.
'
This movement of the lever g g6 is caused by hand by a pull downward of the
cord gl, which connects two levers g12 g17 which are pivotted to the upright A. The
other arms, g3 and g18 of these levers are connected by a rod g¹. The lever g12, 913
is provided with two other arms g14 g11 (Fig. 10). The end of the arm g" is fork
shaped and the end of the arm g5 of the lever g5 g engages with this fork. A pull
downward on the rope g15 will cause the arm gl to be lifted, the lower prong of the
fork lifts the arm g' and lowers the arm go, and disengages its shoulder g' from the
shoulder g*.
The pinion g2 transınits the rotation of the shaft G2 by means of the gear
wheel h to the shaft H. The shaft H is rotatably mounted in the side frames & d
and is provided with teeth h², and further carries the two cams h³ h5 and a chain
gear h. The latter transmits the rotation of the shaft by means of a chain h³ and
another chain gear he to the shaft h10 of the control embroidering machine.
Above the pin wheels e¹ to e¹ are arranged a series of small slides i, one of the latter
for each of the pins e in the pin wheels and one for the flange e° of each pin wheel.
These slides are placed loosely. in slots of a bar I and their heads ¹ rest on the
upper surface of the bar.
The flanges e serve to select a certain punch in the same manner as the pins e. If
the pin wheel is turned in one direction one of the pins e selects a certain punch.
On the other hand if the rotation of the pin wheel is reversed then the flange e°
selects an additional punch which indicates that the direction is opposite to the
normal and the perforations caused thereby on the pattern will on the jacquard
mechanism produce a movement in the opposite direction.
The bar I is secured to two arms 12 on a shaft 3, the latter is rotatively mounted
in the side frames & d, and is provided at its end with an arm it, which carries à bowl
which engages in the grooves h¹ of the gear wheel h (Fig. 10), so that the rotation of
the gear wheel h will cause the bar I and its slides i to be first lowered and then raised
again. Upon each slide i rests the front end of a bolt i³, 1 (Figs. 9, 32, 33). The
rear ends of the bolts at 7 are partly cut away. They are guided in slots of the
punching block I, a bolt being placed over each one of the punches Iº.
When the bar I is moved downward the slides i meeting pins on the pin wheels,
will be prevented from going down with the bar, while all the others will follow the
bar in its downward movement. The front end of the bolts 252 resting on the heads
of the slides i, will be in the high or the low position, according to the position of the
corresponding slide i.
The bolts, are provided near the front end with notches 10, 10 (Figs. 32
and 33) and the lower edges of the two bars 112 enter these notches when the bolts
are in their higher position.
The bars 12 are secured to shafts 213 214, the latter are rotatably mounted
and at their ends are provided with arins 15, 16. The arm 15 by means of the
link is connected to the arm 18 of the two armed lever is, ¿19 mounted
loosely on a stud 220 of the side frame d (Figs. 11 and 34). The other arm 19
carries a bowl which engages with a cam h³. The arm by means of the link 221
is connected with the arm 22 of the two armed lever 122 22 (Figs. 11 and 35)
which is loosely mounted on a stud 23. The other arm 224 carries a bowl which
engages with a cam h³.

page_text: At each rotation of the cam the bars 11, 12 are made to oscillate but not at
the same time. By means of these oscillations the bolts 25, 26, which could not
follow the downward movement of the bar I, are pushed towards the rear and
afterwards towards the front again. The bolts are acted upon by the bar i
and the bolts 26 by the bar . The bolts 25, are further provided with a
nose 25 which limits their backward movement.
The notches 126, 127 of the bolts 15 26 admit of the free oscillation of that bar 11
or 12 which is not intended to act on the corresponding bolts 20 or 25.

punching one row of holes in the Jacquard pattern both rows of punches
co-operate. The object of this construction is to punch the perforations nearer
together than they could otherwise be. J is the die plate which is secured to the
block J¹ on the foundation plate. J2 is the presser plate provided with openings
allowing the punches to pass through and serves to hold the paper firmly to the die
plates while the perforations are being punched or to prevent the paper from being
lifted when the punches withdraw. It is secured to two rods jj (Fig. 9) which latter

arm j carrying a bowl which engages with the cam h³ (Fig. 11). The punch block I¹
is secured to two rods jo (Figs. 9 and 37) passing through corresponding holes in the
die block J. The punch block I¹ is by means of two links je connected to two
arms on a rock shaft j³. An arm secured to the end of this rock shaft carries a
bowl which engages with the cam h³, so that the punch block I¹ at each rotation of.
the cam is lowered and raised, preferably twice for each rotation of the cam.
punches which have been locked by their corresponding bolts are during the down-
ward movement of the punch block forced through the paper, while the punches
whose bolts have not been pushed towards the rear, will follow the downward
movement of the punch block until they reach the paper but will not be forced
through the paper.
The
In addition to the two rows of punches I° are two punches of larger size [5
(Fig. 38). The latter serve to make the perforations which are necessary for guiding
and carrying the Jacquard pattern over the Jacquard cylinder.
Their bolts 10 (Figs. 8, 9, and 39) have a notch j 18.
The bar 12 enters this notch when the front ends of the bolts are in their high
position. The front ends of the bolts 10 can be raised by arms j" on a rock shaft 12
which receives motion from a crank pin jo on a gear wheel 15 by means of a link j¹14.
5 The gear wheel j15 is mounted loosely on a stud 17 of the side frame d and meshes
with the teeth 2 of the shaft H. The bolts 10 are by this means raised and lowered
periodically and the corresponding holes are produced in a Jacquard pattern at
regular intervals. There are further provided four additional punches I° on each
side of the machine which are also arranged in two rows. They are also arranged to
0 be locked by means of bolts whose front ends also rest on slides i of the bar I.
These slides are not acted upon by the pin wheels e¹ to et but by pins e' which are
guided in a flange do of the bearing dd2 (Figs. 9 and 40). These pins can be
moved forward and will then reach under the corresponding slides i and prevent the
latter as also the front ends of the bolts from being lowered (Fig. 41). When
$5 these punches are not to be actuated, the pins e will be in the position shown in
Figs. 9 and 40. The rear end of each of these pins is linked to the lower end of a
two armed lever e' pivotted 'to a stud ee. The upper end of this lever is provided

page_text: with: a nose e8 which engages with a corresponding nose e of triangular piece ell on a
stud eo. By rocking the triangular piece e" the lever e and its pin can be brought
to the position shown in Fig. 41.
The triangular piece el receives its movement from a link e12. The links on each
side of the machine are jointed to common arms e¹³. The two arms e¹³ are secured
to a rock shaft e14 which is further provided with an arm e15 which carries a stud e16.
A bar e18 is pivotted to a bell crank lever e¹ while the front end of it engages with
the stud e on the arm e¹5. The bell crank lever e¹ is mounted loosely on a stud e20
and its other arın carries a bowl which engages with the cam h³.
On the rock shaft e¹ are also two pawls e21, (only one of which can be seen in Figs. 8
and 10). The object of the pawls is to engage with the gear wheels c23 and to pre-
vent any rotation of the pin wheels while the punching takes place. They also pre-
vent the punching mechanism from being set in action when the pin wheels are not
in the proper position. In that case they would strike on the point of the tooth
instead of entering into a space. When the punching mechanism is not in action the
downwardly extending arm of one of these pawls rests on the end of the arm g¹, of
the lever g¹² g³ and the arms e¹³ are thereby maintained in the position shown in
Figs. 9 and 40.
Each link e2 is by means of a rod e22 connected to the end of a lever e23 24 (Fig. 2).
The other end of these levers e23, e24 is connected to the lower end of a rod e25, the
upper end of which is pivotted to a crank pin e28 on a disc e26 (Figs. 3, 42, 43, 44). A
half turn of this disc swings the corresponding lever e³ and brings the link e¹ into
the one or the other of the two positions shown in Figs. 40 and 41. The discs c²0 are
rotated by means of small hand cranks c20.
When by rotation of the hand crank the end of the link e¹2 (Fig. 40) is raised,
then by the next rocking of the shaft e¹ the link e18 strikes against the upper corner
of the triangular piece el2 and rocks the latter into position shown in Fig. 41. The
nose e of the piece e¹¹ in passing the nose es of the lever e', swings the latter and
moves the pin e pivotted to its lower end to the position shown in Fig. 41, so that
the corresponding slide at the next downward movement of the bar I strikes
against the pines and is thereby maintained in its high position and the correspond-
ing punch will then be locked by the bolt. When the link e12 returns again to its
normal position an arm e30 of a link 33 on the lever e¹³ brings the lever e and its pin
back to the normal position, wherein the nose e* rests against the triangular piece e¹¹.
As long as the end of the link el2 remains in its raised position, so long will the trian-
gular piece not again be moved, but when by means of the hand crank e2, the end of
the link e2 is lowered then in its next movement it would strike against the lower.
corner of the triangular piece ell and will move the nose e upward and thereby bring
the lever e² and its pin e' again in a position shown in Fig. 41.
The perforations in the Jacquard pattern made by the punches on the margins are
for the purpose of initiating on the embroidering machines certain special
functions.
For example; stopping of the embroidering machine, connecting and disconnecting
bore attachments, change of shuttle motion, regulation of the tension and the
like.
These special functions by means of suitable connections are transmitted to the
particular mechanism of the control embroidering machine, so that at the same time
that the corresponding perforation in the pattern is produced, the special function is
executed on the controlling embroidering machine.
On a stud d27 of the side frame d is a two armed lever des 29 (Figs. 11, 45, 46).
Its object is to shift the rod d¹³ in the direction of its axis. The arm d2s is
provided with a bowl which engages in the cam h5, the end of its other arm 2
is spiral shaped and engages in or with the corresponding grooves d³ (Fig. 47)
of the collar 2 on the rod d¹³, so that by the rotation of the cam, the lever (28
and 2 oscillates and shifts the rod d¹³ axially.
-
The shaft F by means of the arms f¹ carries the tongs ff and is further provided
at its end with an arm f³ which by means of a link f* (Figs. 11 and 49) is connected

page_text: to an arm f of a bell crank lever f³ f6. The latter is mounted loosely on a
stud f and its arm f is provided with a bowl which engages with a cam h5.
By these means the tongs ƒ ƒ during the rotation of the cam h³ receive a
downward and an upward movement.
The
K and K are two feed cylinders for the perforated jacquard pattern.
shaft k of the lower cylinder is rotatably mounted in the side frames d d. To
the one end of the shaft is secured a ratchet gear k¹ (Figs. 10 and 50), which is
acted upon by two pawls k², k³. The pawl ² serves to retain the ratchet wheel in
position and is secured to the arm of a three armed lever kk ko which is
loosely mounted on a stud 3 of the side frame d. The arm 5 of this lever is
connected by means of a link with the lever . The pawl which serves to
rotate the ratchet wheel is secured to a link 8. This link at its one end is
connected to the arm ko and at its other end by means of another link k° with
the arm of the bell crank lever ko, k10 which is mounted loosely on the stud k¹¹.
The end of the arm 10 carries a bowl which engages with the cam h.
The arm i
serves to alternately engage the pawls, with the ratchet wheel and the bell
crank lever 10 serves to move the pawl ³ so as to rotate the ratchet wheel.
The shaft of the upper cylinder K¹ is rotatably mounted in two arms 13. These
arms are secured to a shaft 14. Springs 15 draw the arms 3 downward and force
the cylinder K¹ against the cylinder K. The cylinder K' is provided with spurs
which engage with the large perforations of the jacquard pattern. The cylinder K
has corresponding holes into which the spurs can enter. The cylinders K K¹ are
provided with gear wheels 17 which are in mesh.
A cylinder 18 serves to receive the jacquard pattern, it can be placed in one or
the other of the bearings 1920 of the side frames d. The cylinder 18 is turned
by means of one of the pawls 21 which act on the ratchet wheel 22 which is
frictionally connected to the cylinder.
These pawls 21 are on a common arm k23, which receives a reciprocating motion
from the eccentric 24 on the shaft H see Fig. 11. The blank paper K2 required for
the jacquard pattern is placed on a cylinder mounted in bearings 25 (Figs. 2 and 3).
It is from there carried down towards the punch block and is passed between
the die plate J and the presser plate J, and from there passed between the
cylinders K and K' to the cylinder K18.
The stopping of the punching mechanism after each action is done automatically.
For this purpose the lever g³ go (Figs. 10, 28, 51) is mounted loosely on a stud 10
on an arin 920. The arm 920 is pivotted on a stud 2 of the side frame d. Its end
is provided with a bowl which engages with the cam h so that at a certain time the
arm g20 moves towards the rear whereby the bell crank lever g³ g4 is turned oppositely
to the arrow (Fig. 28).
The friction clutch G₁ is thereby disengaged from the driving pulley G and
engages with the brake ring G³.
The shaft 10 of the control embroidering machine, by means of the gear h¹ and
intermediate gear h° (Figs. 1, 2, 52, 53, 54) transmits its motion to a gear 12, which
drives the embroidering mechanisın or bore attachment.
The gear 2 is loose on the shaft 13. The shaft h3 operates the needle as
well as the shuttle. On the shaft h¹3 is an arm h which carries a bolt h¹5 which
- can engage with a corresponding hole 1 of the gear h¹ see Fig. 54. The head of
the bolt engages with a slotted block h" on a rod 18. The rod is linked to a
crank pin of one of the discs e26 (Figs. 42 and 43), so that by the turning of the hand
crank 29 the embroidering mechanism may be connected to or disconnected from
the driving gears and at the same time the corresponding punch will be selected to
make the proper perforation in the jacquard pattern at the next action of the
punching mechanism.
To the frame of the control embroidering machine is secured a stud 19 which
is on a line with the shaft h13.
On the stud is mounted loosely a cam h20, to this is secured a disc h21 and in a
hole is carried loosely a bolt h22. The head of the bolt fits into a slotted block 23 on

page_text: a rod h24 which is pivotted to a crank pin on a disc e2 Fig. 42. By rotating the hand
crank the bolt h22 can be shifted and by that means the cam h20 be engaged
with or disengaged from the gear h¹. An interlocking mechanism is provided on
rods 18 and 2 consisting of blocks 25 h25 which prevents the bore attachment
being set in action while the embroidering mechanism is operating and vice versa
(Figs. 52 and 54).
To prevent accidental rotation of the shaft h¹³ or of the cam 20 when disengaged,
there are provided notches h26 on the frame L into which the heads of the bolts are
inserted.
Against the periphery of the cam 20 an arm * carrying a bowl 1 is pressed by a
spring. The arm 2 is secured to a rock shaft 13, which also carries an arm (Fig. 55).
During each rotation of the cam h20 the shaft 3 is rocked and by means of a pawl l³
transmits motion to a boring bar 16. The bar is provided at its end with bore
points. The other end of the bar in its normal position rests against an adjustable
arm 10 drawn against that by a spring 19. The bar is at this end provided with a
number of teeth 12 with which the pawl 15 can engage. In the position shown in
Figs. 55 and 56 the pawl 1 strikes against the stationary stud 13 on the frame I.
and is held disengaged from the teeth (12.
But when the arm 4 with the pawl 15 moves away from the stud (13, then the
pawl 15 is caused to engage with the teeth 12 by a spring and pushes the bar l
forward, whereby one of the bore points 17 or 1 penetrates into the fabric at the
same time compressing the spring 1°. When the pawl 15 returns to the position
shown in the fig. the tooth 12 remains in contact with the pawl under the influence
of the spring 19 until the pawl striking against the stud 113 is disengaged from the
tooth and then the bore will continue its movement until it rests against the
arm (10
By adjusting the position of the arm (10 the relative position of the bore point to
the fabric can be adjusted and thereby the depth of penetration of the bore point
into the fabric. When the position of the arm 10 is changed, then the pawl 15 will
engage with a different tooth. The arm (10 is secured to a shaft which by
means of gearing (15 is connected to the axle of one of the discs e20, Figs. 42, 43 and 44
so that every half revolution of the corresponding hand crank 29 adjusts the
arm 10 to a different position. At the same time the corresponding punch is
selected, which at the next action of the punching mechanism perforates the
jacquard pattern.
The bore point is of square section, having four cutting edges, while the bore
point 18 is round. They are placed at an angle to one another and are secured to a
collar mounted loosely on a stud 110 on the boring bar 16. An arm m on the collar
engages with a slot m¹ of the horizontal arm of an L shaped slide M on the frame L.
(Figs. 2 and 55). The slide M is connected by means of a bell crank lever m² and a
rod m³ with a crank pin on one of the discs e26 (Fig. 42), so that by turning the hand
crank 2 of the disc e26 the slide M can be moved perpendicularly and by that
means, the one or the other of the bore points 17 18 can be brought into the active
position.
The thread is on a bobbin N (Fig. 56), and is carried around a tension n to the
needle bar n¹ and to the needle n².
To regulate the tension a brake n is provided, and bears against the disc n³ by the
action of a spring n5.
The other end of the spring n is connected to an adjustable arm n which is
secured to a rock shaft n which is connected by gearing to the axle of one of the
discs 26. By turning the corresponding hand crank e29 half a revolution at a time, the
arm can be adjusted and thereby the tension regulated. At the same time
the corresponding punch is selected so that during the next action of the punching
mechanisin the proper perforation is made.
The shuttle o in the rear of the control embroidering machine (Figs. 2 and 57)
receives its motion from a cam O.
The shuttle carrier o² is connected to a bar o'. The other end of this bar is connected

page_text: to a sliding block o³, which is provided with a bowl of which engages with grooves oⓇ 07
on cam O. A rotation of the cam gives the shuttle a to and fro motion. According
to the particular kind of stitches to be produced a different movement of the shuttle
is required. For this purpose two cams are provided. The bowl can engage with one.
or the other of these cams by being shifted in the direction of its axis.
This is accomplished by means of a bar o10 having a cam o¹¹ engaging a stud 012 on
a slide carrying the bowl.
The bar 10 is pivotted to a bell crank lever the other arm of which by means of a
rod 08 is pivotted to a crank pin on one of the discs e20, so that by turning the corres-
ponding hand crank e, the bowl can be shifted from one cam to the other and at the
same time the corresponding punch be selected, so that during the next action. of the
punching mechanism the proper perforation is made.
Having described the various parts of the machine, I will now describe its operation.
The design for which a Jacquard pattern is to be perforated is secured to the board a²
and by moving the rectangles B and B' by means of the cords c³, the sight 611 can be
brought to the desired position opposite the design. In doing this, the fabric
frame C of the embroidering machine is brought to its proper position, and the pin
wheels e¹, e, e³, et, are moved from their normal position to the one corresponding to
the distance which the two rectangles have been moved. The pin wheels e¹, e³ are
moved one step after the first half revolution of the pin wheels e², e4, and then one
step after every whole revolution.
The rectangles having been set the cord g15 is pulled whereby the friction clutch
At the same time,
engages with the driving pulley which then rotates the shaft H.
the arm g4 causes the pawl e² to slightly enter spaces of the gears c23. The movement
of the pawls e21 is then completed by the action of the cam h5 on the lever e¹9 and on
the shaft e14, and the pawls are thereby fully entered in said spaces of the gears, while
at the same time the links e13 are pushed, and one or more of the pins e brought in
position shown in Fig. 41. The cam h by means of the lever lowers the bar I
whereby the slides i which meet no pins, on pin wheels e¹-e, are lowered while those
which meet such pins remain in their raised position, together with the ends of the
bolts 25, 26. Then the pawl 2 is withdrawn from the gear and the pawl k³ is
entered. By means of the levers 19 18 15 the shaft 13 is rocked and thereby the
bolts which have remained in the raised position are pushed towards the rear and
the corresponding punches 20 are locked. The cam h³ then acts on the arm Jº
whereby the punching block I¹ is lowered. The punches in the front row which have
been locked perforate the pattern. The punching block is raised again, the bolts 25
are returned to their normal position. The cam acting on the arm 920 moves the
lever g g towards the front.
By means of the levers 224, 222 and 16 and link 21 the cam 5 rocks the shaft 14 and
thereby pushes the bolts which are in the high position towards the rear and locks
the corresponding punches. At the same time the shaft j2 is rocked and lifts the
pressure plate J2, and then the cam acting on the arm 10 moves the pawl thereby
turning the gear k¹ and the cylinders K K¹ thereby drawing the paper K2 one step
towards the rear, so that that part of the paper which had been under the front row
of punches is now brought exactly under the second row of punches, so that any per-
forations made by the second row of punches are exactly in line with per-
forations made by the front row, then the punch block I¹ is again lowered. The
punches which are locked perforate the paper, the pressure plate. in the meantime
having again been lowered is forced on the paper by the springs j¹. The punching
block I is again raised and the bolts are drawn back to their normal position.
The further rotation of the cam h acting on the arm d, causes the spiral shaped
end d30 of the other arm 24 to act on the corresponding grooves 31 of the block d³2
and thereby to shift the rod 13 in the direction of the arrow u (Fig. 16) causing the
bolts d1, d23 to be withdrawn from the holes in the discs ds, d24.
The pin
wheels e¹, e², e, e are thereby disconnected from the gears c23 so that the pin wheels
may be returned to their normal position. The bar I will now be raised and the arm it

page_text: lowered, whereby the pawl k³ is disengaged from, and the pawl k² engaged with the
gear ¹.
By means of the arms ƒ³, ƒ³, ƒ³ and the link f, the cam h³ rocks the shaft F moving
the arms f' downward.
The tongs ff connected to said arms f¹, return the pin wheels, e¹, e², e³, e¹ to their
norinal position.
The arm 29 now moving downward enters the bolts d¹², 23 into the corresponding
holes of the disc d³ d24, and then by rocking the shaft F the tongs ff are again
returned to their normal position, (Figs. 10, 11, 24, 25). By the return movement of
the lever e¹8, the pawls e21 are withdrawn from the gear wheels c23. By the action of
the cam on the lever 920 the lever 95, 96 is pushed towards the rear, whereby the
shoulder g' of the arm 9 acting against the shoulder gs of the arm g' brings the bell
crank lever g, g3 into the position shown in Figs. 27 and 28, and thereby withdraws
the friction clutch from the driving pulley and engages the same with the brake ring,
whereby the machine is stopped.
The rectangles can now be moved to the position corresponding to the next
stitch and so on.
During every action of the machine, while the punching mechanism perforates
the jacquard pattern the complete embroidering corresponding to the design is
produced on the control embroidery, machine, which stitches, bores and performs
the other functions that may be necessary so that the operator can at all times
verify the correctness of the work done.
When any of the special functions already referred to such as stopping of the
machine, disconnecting of the sewing inechanism and the like, are required, a
corresponding perforation in the pattern is made and the corresponding action on
the control embroidering machine performed.
When the bore attachment needs to be put in action, the operator moves the
corresponding handle e29, whereby the boring mechanism of the controlling machine
is connected and a corresponding punch of the punching mechanism is selected.
On the control embroidering machine, the bore point is some distance below the
needle and in changing from stitching to boring, the fabric frame is to be lowered
that much.
Then it becomes necessary to move the board the corresponding distance. The
hand crank a and its connections are provided for this purpose. After moving the
board the rectangles B B' are brought to the same point on the design where they
were previous to the board being moved. The distance which the board a² is moved
and the distance which the fabric frame C° is moved corresponds exactly to the
distance between the bore point and the needle. Changing back from the boring
action to embroidering the board a² will be again returned to the former position,
and the rectangles likewise.
Large designs, that is, designs of greater dimension than can be accommodated on
the machine, will be put on in parts. When the rectangles B B¹ have reached
their limit, the pattern can be taken off and a new portion put in its place on the
board. By shifting the handle c30 on the rod c in the direction of the arrow v
(Fig. 8) the discs c¹ and the rectangles B and B' will be disconnected from the pin
wheels e¹, e², e³, e, and the fabric frame of the control embroidering machine. The
teeth on collars c³1 engage with gears 23 preventing the latter from accidental
rotation. The rectangles may now be moved so as to bring them to the
proper point on the new design, whereupon the discs c may again be connected with
the other mechanism.
