Improvements in or relating to Jacquard Mechanism for Embroidery
Machines.
I HENRY HILL of the Firm of Balm Hill & Sons 63a Mansfield Road, in
the Borough of Nottingham, Lace Manufacturer do hereby declare the nature of
this invention to be as follows:-
This invention relates to what are known as multiple embroidery machines, in
which the tissue or fabric to be embroidered is mounted on a vertical frame which
is usually moved each stitch by means of a pantograph operated by an attendant,
and it has for its object to provide Jacquard mechanism for automatically moving
the embroidery frame each stitch in any direction required, either acting direct on
the frame or through the intermediary of a pantograph of the usual construction.
When the movement is imparted directly to the embroidery frame without the
intermediary of a pantograph I preferably employ a horizontal screw and nut for
moving the frame horizontally, a vertical screw and nut for moving the frame
vertically and the combined action of both screws for moving the frame in any
other direction.
The horizontal screw is preferably arranged at one end of the embroidery frame
and is carried in a threaded nut or sleeve which in turn is mounted in a bearing
secured to the end standard of the machine, the screw is preferably fixed and the
nut rotated, although this order may be reversed.
At the end of the screw is a block engaging with a vertical slide secured to the
embroidery frame, this block is also mounted on a pin or slide placed parallel to
the screw in order to steady it.
With this arrangement the frame may be moved horizontally by rotating the nut
without limiting its vertical movement, as the vertical slide on the frame is
capable of sliding vertically in the block at the end of the screw.
Secured to or formed on the nut or sleeve is a pinion and engaging with this
pinion is a second intermediate pinion mounted on an axle secured to a lever
pivotted on the nut or sleeve, or sleeve bearing. This lever is connected to the
jacquard and the pinion is thus moved into engagement with the teeth of one of two
racks placed on each side of the two pinions, both of which latter are normally out
of engagement with the former.
The two racks are mounted upon a preferably vertical slide which is connected
to the jacquard, the latter moves the slide from its normal position each stitch the
requisite distance but always in the same direction, and it is again returned to its
normal position by a spring or weight. The intermediate pinion is also moved
into engagement with the rack on one side or the other, by means of the jacquard
according to the direction it is desired to rotate the nut.
The vertical screw is preferably arranged centrally above the frame and it may
be connected to the frame and be mounted in the same manner as the horizontal
screw, the bearing for the nut or sleeve being in this case secured to the two top
rails of the machine.
In some cases the screw may be connected to the counterweight and its
movement be communicated to the frame through the weight and the levers which
connect the weight to the frame.
To reduce the vibration however I preferably employ a screw to move both the
weight and the frame simultaneously one part having a right hand thread and

page_text: the other a felt hand thread so as to raise the frame as the weight is lowered
and vice versa.
This screw is mounted near the middle in a bearing secured to the two top rails,
and at the upper end in a second bearing carried by two standards each secured to
one of the top rails before mentioned.
On the upper part of the screw is a nut secured to or engaging with the
counterweight, or the screw may pass axially through the weight and the levers
formed with forked and slotted ends to engage with pins on each side of the
weight. If preferred the levers may be arranged in the form of a parallel motion"
and the centre of the link be connected to the weight.
On the lower end of the screw is a threaded sleeve or plunger carried by and
sliding vertically in an extension of the screw bearing, the lower end of this sleeve
or plunger is connected to a horizontal slide secured to the frame.
Secured on the screw is a pinion by means of which it is rotated in either
direction by an arrangement which may be a duplicate of that used for operating
the horizontal screw.
The jacquard which may be placed in any convenient position is provided with
a cylinder for the pattern cards, a cage in which are droppers preferably arranged
in two rows parallel to the axis of the cylinder, which latter is formed with two
corresponding rows of holes.
Above the droppers is a slide which has a constant reciprocating motion in a
line parallel to the axis of the cylinder, facing the end of this reciprocating slide
are two stationary slides and the latter are moved by the interposition of the heads
of the droppers between the ends of the reciprocating and the stationary slides,
the length of the movement of the latter being determined by the number of
droppers raised by the pattern card.
Each stationary slide is connected to one of the double rack-slides hereinbefore
described in connection with the horizontal and vertical screws, and the length of
movement of the double racks is thus governed by the number of droppers raised
by the pattern card.
The dropper cage is mounted loosely on two parallel shafts or a slide and is
connected to the reciprocating slide so as to reciprocate with the latter on the said
shafts or slide. The droppers raised in each row are maintained in their raised
position during this movement, by a pivotted locker bar which engages with a
recess in the body of each dropper in the row. Both locker bars are operated so
as to release the droppers by a vertical slider working in guides in the dropper
cage, and operated by the cylinder as it rises to select the droppers for the
next movement.
In addition to the above, four vertical sliders are carried in vertical guides in
the dropper cage, holes are also formed in the cylinder corresponding to the
position of the pins on these sliders. When the dropper cage is in its normal or
selecting position these sliders engage with four vertical selector needles carried in
fixed sleys or brackets secured to the framing, these selector needles in turn
engage with four selector bars each provided with a tooth or projection which
normally engages with a reciprocating block but miss it when raised by the pattern
card through the intermediary of the vertical sliders and selectors. The four
selector bars are arranged in pairs, one pair being connected to the intermediate
pinion lever of the horizontal screw and the other pair to the intermediate pinion
fever of the vertical screw. One selector bar in each pair is connected to an arm
on one side of its corresponding pinion lever, and the other to an arm on the
opposite so that by selecting either of the bars the pinion may be moved to one
side or the other and into engagement with either of the racks on the slide.
The operative parts in the jacquard are timed so that the movement of the
pinions immediately precedes that of the racks, and on the completion of the latter
movement, the selector bars are all returned to their normal position by the
reciprocating block, this movement returns the pinions to their normal position and
permits of the like return of the racks.

page_text: When the movement is imparted to the embroidery frame through the
intermediary of a pantograph, the free end of the operating arm of the latter is
provided with a pin or axle which engages in a horizontal parallel slot or slide in
a horizontal frame. The two ends of this frame are secured to two vertical racks,
which latter engage with pinions on a horizontal shaft.
By turning this horizontal shaft the horizontal slotted frame or slide may be
raised or lowered and a corresponding movement imparted to the free end of the
pantograph arm. The pin or axle at the free end of the pantograph arm also
engages with a vertical slotted frame or slide carried by two horizontal racks,
which latter engage with pinions on a vertical shaft, and is a duplicate of the
mechanism previously described but arranged so as to move the end of the
pantograph arm horizontally to the right or left.
The whole arrangement is carried by a vertical framing placed in front of or
substituted for the pantograph board.
By the independent or combined movements of the horizontal and vertical
slotted frames or slides, the free end of the pantograph arm may be moved in any
direction in a plane parallel to the embroidery frame and this movement is
imparted to the said frame by the pantograph in the usual manner.
The requisite movement may be imparted to the horizontal and vertical shafts
by the same mechanism as that described in the previous arrangement for
operating the screws.

Improvements in or relating to Jacquard Mechanism for Embroidery
Machines.
I, HENRY HILL, of. the Firm of Balm, Hill & Sons, 63a, Mansfield Road, in
the Borough of Nottingham, Lace Manufacturer, do hereby declare the nature of
this invention to be particularly described and ascertained in and by the following
statement.
This invention relates to what are known as multiple embroidery machines in
which the fabric to be embroidered is mounted on a vertical frame which is moved
each stitch, the needles being stationary.
In the present invention, the embroidery frame is moved each stitch in the
required direction by the action of two screws, one screw being arranged to move
the frame in a direction which is at right angles to the direction of the movement
imparted to the said frame by the other screw.
The frame is moved any intermediate distance between two extremes, in any
direction, by rotating either one of the screws or both screws together, through
the required angular space and also in the requisite direction.
The amplitude of the movement of the screws determines the length of the
movement of the frame, whilst the amplitude of the movement of one screw in
relation to that of the other and the direction in which each screw is rotated
determines the direction in which the frame is moved.
The main object of this invention is to provide improved means for automatically
imparting the requisite movement to each screw each stitch.
The invention will be best understood by reference to the accompanying
drawings in which :—
Fig. 1 is a front elevation showing my invention applied to a multiple shuttle
embroidery machine, parts only of the latter being shown.
Fig. 2 is a front elevation, and

Fig. 10 is a vertical cross section showing a detail of the jacquard construction.
Fig. 11 is an elevation and
Fig. 12 a plan showing change gear applied to the screw operating mechanism.
Figs. 2 to 12 inclusive are drawn to a larger scale than Fig. 1.
Like letters indicate like parts throughout the drawings.
The embroidery frame A. Fig. 1, is moved in a horizontal direction by a
horizontal screw B, and in a vertical direction by a vertical screw C and in any
other direction intermediate between the horizontal and vertical, by the combined
action of both screws.
In the latter case the frame A makes a movement which is the result of the
action of the two screws, one moving the frame at right angles to the other.
The horizontal screw B (Figs. 1, 2 and 3) is preferably placed at one end of
the embroidery frame, and is carried in a threaded nut or sleeve E, which in turn
is mounted in a bearing B' secured to the end standard D of the machine. The
screw B is preferably fixed and the nut or sleeve rotated as shown, although this
order may be reversed if desired.
Secured to the end of the screw B is a block B2 which engages with a vertical
slide A on the embroidery frame A, this block B2 is also supported by mounting
it loosely on a fixed pin B³ or a slide, placed parallel to the screw.
With this arrangement the embroidery frame A may be moved horizontally by
rotating the nut or sleeve E without limiting or interfering with its vertical move-
ment, by reason of the vertical slide A on the frame A being free to slide in the
block B at the end of the screw B.
Secured to or formed on the end of the nut or sleeve E is a pinion E¹, and
engaging with this pinion E' is a second intermediate pinion E³, the latter is on a
pin or axle E3 secured to one arm F of a three armed lever FF1 F³ pivotted on
the exterior of the bearing B'.
The arms F F are connected by rods F3 F4 to the jacquard hereinafter
described, so that the intermediate pinion E' may be moved from its normal
position in which it is shown, into engagement with the teeth of either of the two
racks G G¹ which are on opposite sides of the pinions E¹E².
The racks G G are secured to or formed on a frame G³ provided with
shafts G3 G3 which are carried by and slide longitudinally in bearings GʻGʻ,
secured to the standard D of the machine.
The frame G2 is connected to the jacquard by a chain G³ attached to a boss G
secured on one of the shafts G³.
The vertical screw C (Fig. 1.) is preferably arranged centrally above the
embroidery frame A. and it may be mounted and connected to the frame in the
same manner as the horizontal screw, the bearing for the nut or sleeve being in
this case secured to the top stays H of the machine.
To reduce vibration however I preferably employ a vertical screw to move both
the frame and counterweight C³ simultaneously as shown, one part of the screw
having a right hand thread, and the other a left hand thread, so as to raise the
frame and at the same time lower the weight and vice versa.
The vertical screw C (Fig. 1, 4 and 5) is mounted near the middle in a bracket
bearing Csecured to the two top stays H, and at the upper end in a second
bearing H carried by two standards H2H secured to the before mentioned
stays H.
On the upper part of the screw C is a nut C² secured to the upper part of the

page_text: counterweight C the latter being formed with an axial hole for the passage of the
screw. The levers I are formed with forked and slotted ends I¹ which engage
with pins I2 on each side of the weight, or the levers may be connected to the
weight by links preferably arranged in the form of a parallel motion.
On the lower end of the screw C is a threaded sleeve or plunger C+ carried by
and sliding in an extension C of the bearing C¹. The lower end of the sleeve C
engages with a horizontal slide A² (Figs. 4 and 6) secured on the frame A, so that
it may raise or lower the frame A without interfering or limiting its horizontal
movement to the right or left.
The vertical screw C is operated by an arrangement which is a duplicate of that
employed for operating the nut or sleeve E of the horizontal screw, and comprises
a pinion J secured to the screw C, an intermediate pinion J2 mounted on a pin or
axle J3 secured to one arm K of a three armed lever K K K2, which is pivotted
on the exterior of the bearing C₁, rods K3 K for connecting the armз K' K' to
the jacquard, and racks L L carried by a frame L' provided with shafts L³ L³
mounted in bearings L secured to the cross stays H³ of the standards H³.
The rack frame Lis connected to the jacquard by a rod L' attached to a
boss L secured to one of the shafts L³ in the same manner as the rack frame of
the horizontal screw.
The racks and screws are operated by the jacquard as follows:-
In order to move the frame A horizontally to the right or left, the pinion E' is
moved into engagement with one of the racks G G₁, the rack frame G is then
moved from its normal position in which it is shown, to a point which is deter-
mined by the length of movement it is desired to give the frame A, the pinion E'
is then first returned to its normal position followed by a like movement of the
rack frame G2 ready for the next movement. The return movement of the rack
frames G2 and L' may be performed by weights or springs which are not shown.
In order to raise or lower the frame A in a vertical direction, the pinion J³ and
rack frame L2 are operated in like manner.
In order to move the frame in a diagonal direction both pinions E' and J' and
both rack frames G2 and L' are operated, and the frame A will be moved in a
direction which is diagonally across a rectangle the two sides of which correspond
to the direction of and length of the two movements imparted to the frame by the
horizontal and vertical screws.
It will be seen that the direction of the movement of the frame A, is
determined by moving the intermediate pinions E2 and J' into engagement with
one of the two corresponding racks, and that the extent of such movement
of the frame is determined by the length of the transverse of the rack frames G³
and L.
These movements are given by a jacquard of special construction which is
placed at the end of the machine and is carried on two horizontal rails M M.
(Figs. 1, 7, 8 and 9) which are secured at their inner ends to the standard D of
the machine and supported at their outer ends by a pillar M.
The frame of the jacquard is formed by two plates M2 M2 secured to the
beforementioned rails M M, and the driving shaft M' of the jacquard which is
carried in bearings M³ secured to one of the plates M2, is connected to the main
driving shaft M of the embroidery machine by a vertical shaft M³ and toothed
wheels M M* M* M*.
In embroidery machines which vary in construction from the one shown, the
driving shaft M' of the jacquard may be connected to the embroidery machine by
other means if found more convenient.
The jacquard (Fig. 7, 8 and 9.) is provided with a pattern card cylinder N and
a dropper cage N¹ in which the droppers N are arranged in two rows parallel to
the axis of the cylinder N, the latter being formed with two corresponding rows of
holes N³ N³.
The dropper cage N¹ is mounted loosely on two shafts N* N* which are
supported in the two end plates M. Above the dropper cage N' is a horizontal

page_text: driving slide O which is supported in guides O' secured to or forming part of one
of the plates M2, this slide O is reciprocated by a lever O² (Fig. 7) actuated by a
cam 03 on the main shaft M².
The slide is connected to the dropper cage N¹ by a pin 01' on the former
engaging with a slot in the latter, and the cage N¹ is thus reciprocated
longitudinally on the shafts N' simultaneously with the driving slide O.
Opposite to the slide are two abutments P P secured to shafts P2 p³
respectively, the shafts P2 P3 are mounted loosely and are capable of being moved
longitudinally in bearings P P P P secured to or forming parts of the
plates M² M².
The abutments P P' and corresponding shafts P2 P3 are moved longitudinally
by the interposition of the two rows, of droppers N2 between the driving slide O
and the abutments, the distance of the movement of each abutment being
determined by the number of droppers N' raised in each corresponding row by the
pattern card."
The shaft P2 (Fig. 8.) is connected by the rod L' to the rack frame L2 (Fig. 1)
of the vertical screw C, and the shaft P³ by the chain G' to the rack frame G² of
the horizontal screw B, the said chain G being carried over a pulley S pivotted
on a bracket secured to one of the rails M.
The length of the movement of each rack frame L2 and G2 is therefore
determined by the number of droppers raised by the pattern card in each
corresponding row.
The droppers N in each row (Fig. 9.) are held in their raised position during
the traverse of the cage N' by longitudinal locking bars N³, the upper edges of
which engage with the catches N° on the droppers.
The locking bars N³ are pivotted at N' in the frame of the dropper cage N¹ and
are opened out in order to release the droppers, by a vertical slide Q (Fig. 10)
which is raised by the cylinder, this slide Q is provided with two pivotted
catches the movement of each of which is governed by stops Q2 Q2 so that the
said catches Q1 Q¹ open out the locker bars N' as the slide Q is raised by
the cylinder, and fold on the slide as the latter returns to its normal position.
In addition to the parts of the jacquard herein before described for operating the
rack frames L2 G2, is the mechanism for moving the intermediate pinions J2 E³
into gear with the racks, the latter being arranged so as to be governed by the
same pattern card as the former.
For this purpose mounted loosely on the shafts P2 P3 is a block R (Figs. 6, 7
& 8) which is reciprocated longitudinally on the shafts P2 P3 by a cam R¹ (Fig. 7.)
on the cam shaft M' through a lever K2 and link R³. Resting on the upper face
of this block R are the ends of the rods F F K³ K* previously described which at
this point are each provided with a catch K to engage with the edge R₁ of the
.block R.
The ends of the rods F3 F* K* K* may be raised as desired so that their catches K³
are not engaged by the block R, by vertical selectors U. U. U. U. carried in
frames U Usupported by brackets U2 U2 secured to the rails M. When the dropper
cage N is in its normal position the selectors U. U. U. U. engage with the upper ends
of four corresponding vertical T shaped slides V. V. V. V. carried in the middle of the
dropper cage, these slides are together with the selectors raised by the pattern card
in the same manner as the droppers, holes V₁ being formed in the cylinder N
corresponding to the position of the said slides. It will be seen that the
rods F3 F4 K3 K4 are arranged in pairs both rods F³ and F* operating the
pinion E and the rods K³ K the pinion J', it will thus be understood that by
selecting either of the rods in each pair each pinion may be moved into engage-
ment with either of its two operating racks.
For example if the rod engages with the block R, the pinion E will be
moved into engagement with the rack G¹, if on the contrary the rod F³ were
engaged with the block R the pinion E would engage with the rack G. It will
also be seen, for example, that if the rod F' be moved by the block R the rod F

page_text: will also be moved in the reverse direction. In order therefore to return the
pinion E to its normal position it is only necessary for the block R to return until
it engages with the rod F which has now been released by its selector U and by
means of the said rod F return the pinion to its normal position, before the return
movement of the rack frame G2 commences. The pinions E2 J2 may however be
returned to their normal position by springs.
The horizontal and vertical parts of the rods F3 F4 (Fig. 1.) are connected by
bell crank levers Fe (one only of which is shown) pivotted to the bracket S¹.
It may be noted that the racks must be traversed through a space equal to the
pitch of the rack or a multiple of the pitch, and that each screw will move the
frame through a space which is a fraction of the length of movement of the rack,
the value of the fraction is constant, it being determined by the pitch of the screw
and the number of teeth in the pinion on the screw.
In order that the length of the fractional movement of the frame with respect to
that of the rack may be conveniently adjusted to suit different classes of work, the
pinion J2, for example, (see Figs. 11 & 12) instead of gearing directly with the
pinion J¹ on the screw C as previously described, may be connected by two change
wheels Y Y as shown.
The pinion Y may be mounted on the same axle J³ as the pinion J2 and be
connected to the latter or be mounted on a sleeve or boss of the pinion J2 so as to
be.readily detached. The pinion Y₁ is mounted loosely on an axle Y³ which is
adjustable in a slot in an arm Y* and the latter is mounted loosely on the screw C,
the arm Y may be held in position by a slotted link Y one end of which is
pivotted on the upper end of the axle J3 and its slotted end is bolted to the
arm Y
With this arrangement wheels having the requisite number of teeth to give any
required result may be substituted for the wheels Y Y¹ the position of the axis of
the latter being adjustable.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
