PROVISIONAL SPECIFICATION left by the said Friedrich Eduard August
Büsche at the Office of the Commissioners of Patents on the 14th July 1882.
FRIEDRICH EDUARD AUGUST BUSCHE of Schwelm, Westphalia in the Empire"
of Germany, Manufacturer "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR
THE MANUFACTURE OF LACE AND OTHER LIKE ORNAMENTAL FABRICS APPLICABLE
ALSO TO THE MANUFACTURE OF ORNAMENTAL OR PLAIN BRAIDS "
This Invention relates to a peculiar construction and arrangement of machinery
or apparatus capable of being driven by hand or by power for the manufacture of
a class of Lace which has hitherto commercially only been made by hand such for
example as real "Torchon" lace "Valencienne" lace and the like.
In my improved machine the bobbin carriers are driven in a similar manner
to that adopted in what is known as the "German braiding machine" but
according to my invention I arrange the bobbin carriers and their driving wheels
in an arc or segment of a circle disposed in a vertical plane although in some
cases I may arrange them as in the common braiding machine and may employ
from 1 to 4 rows connected together or not as required and when connected
allowing or not the bobbin carriers to travel over any two or more of the
connected rows: in the latter case I introduce between each two pairs of notched
disc wheels a small upright or standard carrying the requisite guiding fingers or
directors.
In my improved machine some or all of the notched disc wheels employed for
driving the bobbin carriers are so arranged as to admit of their engaging with and
being disengaged from the said carriers by sliding along their fixed pivots or
D 1071

page_text: spindles or the rotary motion of the notched discs which are by preference separate
from their driving wheels is arrested by a sliding clutch arrangement.
I propose according to my invention to effect the sliding motion of the notched
disc by either or any of the following mechanical arrangements.
First. I employ a forked arm embracing the boss of the notched disc and acted
upon by a screw or spiral thread or threads the said forked arm being guided
by a fixed stud or pin at the opposite end to the fork. The notched disc is
separate or not from its driving wheel and slides when separate by a slot and
feather along the boss of the said wheel in company with which it is caused to
rotate. The said screw or spiral threads are carried by or formed on a rocking
spindle acted upon by jacquard mechanism through suitable connectors.
Secondly. The said screw or spiral threads form the upper part of a central
spindle passing through and resting upon the top of the fixed hollow pivot of the
notched disc wheel a travelling nut on the said screw being provided with forked
arms one passing down on each side of the screw through the disc of the guiding
plate situate on the said pivot the said forked arms bearing upon the notched disc
so as to move it downwards thus dispensing with the before mentioned sliding
The upward sliding motion of the notched disc may be effected by a spring
or both movements may be positive movements.
arm.
Thirdly. In lieu of a screw thread a collar is employed having one or more
lateral projecting studs and mounted so as to turn partly round upon the hollow
portion of the pivot of the notched disc wheel. The said collar is connected with a
rocking spindle inside the said pivot by a pin passing through a horizontal slot in
the side of the hollow pivot. The inner or rocking spindle is rocked or worked
by suitable connections from a jacquard machine. The lateral projecting studs of
the said collar engage into spiral or inclined slots formed in an outer collar which
acts as a travelling nut and is prevented from turning by a longitudinal slot and
guide fixed on the pivot just above the driving wheel. Two internal horizontal
grooves in the upper end of the said travelling nut serve to couple the same with
the notched disc which is free to turn therein. The required rotary motion of the
notched disc is obtained from the usual toothed driving wheel by a finger secured
to the boss of the said wheel and engaging at its upper end with a vertical slot in
a lateral projection on the lower part of the notched disc the said finger being free
to revolve round the outside of the travelling nut or collar containing the spiral or
inclined slots.
Fourthly. By a slight modification of the last described arrangement the spiral
or inclined slots can be made in the fixed hollow pivot the inner central rocking
spindle of which carries a transverse pin passing through such slots and secured to
the sides of a sliding collar having a partial rotary motion along with the said
rocking spindle and being connected as before described to the notched disc.
In cases where the rotary motion of the notched discs is arrested the actuating
or governing parts may be the same as above described and may operate upon an
intermediate sliding and rotating clutch provided with a finger engaging when
elevated with the projections on the notched disc such projections corresponding
with the notches in the said disc. Or fingers mounted on, turning with, and
'sliding along the boss of the driving wheel may be caused to engage with a small
ring forming the upper part of the sliding collar containing the spiral or inclined
slots. One of the sliding fingers being longer than the other its upper end when
lifted engages direct with one of the before mentioned lateral projections of the
notched disc.
In order that the bobbin carriers may more accurately adapt themselves to any
slight irregularities in the guide plate and to ensure greater steadiness and
stability of the said carriers in any position upon the guide plate I propose to
make one or both the sliding or supporting flanges of the bobbin carrier self
adjusting by means of a spring or springs. This arrangement although more
particularly useful when using a guide plate curved in a vertical plane may
obviously be employed in connection with a flat guide plate:

page_text: I further employ in my improved machine a novel arrangement of beaters which
I work in a peculiar manner for pushing the crossings towards the braiding point
such beaters being controlled or not as preferred by a jacquard or pattern
mechanism. These beaters are mounted on and slide along adjustable guide rails
disposed radially from below the braiding point towards the notched disc wheels
the said rails being adjustable nearer together or farther apart at their upper ends
according to the class of work to be produced. Along each of these guide rails
works the slide of the beater to which slide there is hinged or pivotted on the
side towards the work a lever arm constituting the beater proper which is guided
and kept steady by a guide in the upper part of the slide. When not in action
(at the lowest position) the beater is kept by means of a stationary bar in an
outward position or away from the range of threads in order to allow the latter
to pass and cross freely. When the beater rises again by the upward movement
of the slide it releases itself from the stationary bar and is by means of a spring
forced inwards towards the range of threads and between the crossings of its
corresponding threads so that the continuation of the upward sliding movement
of the beater carries up along with it the crossing to the required position where
it is operated upon by other mechanism hereinafter described. When the slide
with the beater descends again one end of a bell crank lever by preference mounted
on the upper part of the slide comes in contact with a fixed pin or stud in the
guide rail which it had passed freely in its upward motion by reason of its being
provided with a self acting spring-jointed catch which moves out of the way on
the upward movement but is rigid when striking the stud in its downward
movement. The opposite end of the said bell crank lever by acting against
a stud in the beater arm draws the beater arm towards the guide rail and away
from the range of threads in which position it is maintained locked by a catch
on the lower end of the beater itself until the said catch is released by striking
against a fixed stop such release' taking place just before the slide reaches the
lowest position. The beater is then allowed to rise again slightly so as to bring it
in contact with the before mentioned stationary bar after which the operations
of the beater will be repeated when required as previously described. The upward
and downward movements of the slide along its rail are produced in the following
manner. On the opposite side of the slide to that which carries the beater proper
there is hinged at its upper end a vertical hooked lever guided or steadied below
the hook by a projection on the slide so as to form together with such hook
a notch for the reception of the edge of the lifter bar hereinafter referred to. The
tail or lower end of this vertical hooked lever is so bent or incliued as to slide
or not as required along the upper end of a controlling lever mounted on a fixed
axis and towards which the hooked lever is pressed by a spring the position of
such controlling lever being governed or controlled by a jacquard machine. When
the controlling lever is brought by the jacquard machine into such a position as
that the tail of the hooked lever (on the descent of the beater mechanism) shall
slide along it the hook will be thereby brought out of the range of the lifter bar
above referred to. This lifter bar is carried in a sliding frame which receives a
regular up and down movement from a rotary crank or other mechanical con-
trivance driven by suitable gearing from the main driving shaft of the machine.
and at such a speed as may be required for the pushing up of the crossings as they
occur. The said lifter bar is provided with springs which allow it to move a short
distance vertically downwards in its holders attached to the sliding frame when
it encounters fixed stops which occur a short time before the sliding frame
completes its upward movement this provision being made in order to allow of
a certain pause or dwell in the movement of the beaters at the termination of their
upward stroke for the purpose hereinafter described. The upper part of the before
mentioned vertical hooked lever is so inclined as that the lifter bar on its descent
shall be enabled to engage itself automatically with the hook of the said lever in
which condition the corresponding beater will be brought into action but it will

page_text: remain at rest as long as the controlling lever keeps the hooked lever out of the
range of the lifter bar as before described.
I further employ in my improved machine a peculiar arrangement of needle
mechanism in combination with "take-up" rollers governed by a jacquard machine
for taking up the thread crossings or meshes and maintaining them in their proper
relative positions whilst the work is proceeding. The needle mechanism consists
of two ascending and descending frames each carrying a range of horizontal
needles. The vertical movements of the two frames are independent of each other
and take place alternately, they are governed by a jacquard machine which also
governs the movements of the needles contained in such frames. One range of
· needles is lowered to the position to which the beaters have brought the crossings
or meshes and such of the needles as may be required are then allowed to move
outwards either by the action of springs or by the positive action of the jacquard
machine so as to enter the corresponding crossings or meshes, the before mentioned
pause or dwell in the movement of the beaters affording sufficient time for the
needles to enter. In order to facilitate the engagement of the needles with the
said crossings or meshes I either form the head of the beater with a groove in a
line with its corresponding needle into which groove the needle enters when
pushed forward or I provide the head of the beater with a number of bristles or
their equivalent disposed close together longitudinally and in a line with the
corresponding needle in such manner as to allow of the needles penetrating the
bundle of bristles and engaging with the crossings or meshes which are left thereon
by the beaters in their descent. On the completion of the row of meshes in the
same line which I will call the first row the range of needles is lifted to the
braiding point situate just below the "take up" rollers. The second frame of
needles which is opposed to the first is now caused to descend and take the next
or second row of meshes it then rises and brings this row into the proper relative
position to the previous or first row of meshes. The needles of this first row are
now withdrawn and with their mechanism caused to descend to take up a third
row of meshes as before described. During this latter action the “take-up" rollers
which have been at rest since the taking up of the first row now commence to
rotate in order to take up the work and bring the second row into the position
previously occupied by the first row the range of needles of this second row rising
along with the work thus maintaining or preserving the meshes intervening
between the "take-up "rollers and these needles. The second row of meshes
having thus reached the previous position of the first row the rotation of the
take-up" rollers as well as the lifting motion of the said range of needles
ceases and the operations are repeated for the third row and so on as before
described.
«
The above described combination of "take-up" rollers and needle mechanism
with their driving gear is by preference carried by a slide having a to-and-fro
lateral motion governed by a jacquard machine in order to afford facility for
imitating in every respect the peculiarities of hand-made lace which frequently
require to work parts of the fabric at certain times closer together (in a lateral
direction) or farther apart than at other times.
According to another arrangement for fixing the rows of meshes and conducting
the work towards the "take-up" rollers I employ a hollow cylinder having its
circumference perforated with radially disposed openings containing each a needle
so made as to work with a certain amount of inherent elastic friction in the
cylinder whereby each needle will remain steady in its outward or inward position
in its corresponding opening. This cylinder is mounted on a horizontal axis
which receives a slow rotary motion in either direction required under the control
of a jacquard machine. Inside this cylinder there is provided a stationary bar
through which work radially to the cylinder a row of pushers governed in their
action by a jacquard machine such row of pushers corresponding to the different
longitudinal rows of perforations with their respective needles in the cylinder as

page_text: they are brought round. These needles are pushed outwards so as to protrude
beyond the surface of the cylinder by the pushers as the pattern may require the
pushers immediately returning to their normal positions whilst those needles
which have been protruded remain stationary until pushed inwards either by the
action of a curved eccentric surface or otherwise. The said radial needles are
protruded for the purpose of entering the meshes brought up by the beaters
directly or by the intervention of one of the herein before described needle
mechanisms. The needles of the cylinder thus maintain and fix the meshes until
the work is sufficiently stable to admit of its leaving the needles successively and
being drawn away by the "take-up" rollers which rotate in concert with the
needle cylinder.
The herein before described lace-making machine may be applied to the manu-
facture of plain or ornamental braids and when making plain braids it may be
greatly simplified by dispensing with the needle mechanisms, employing the
ordinary arrangement of notched disc wheels and imparting a regular movement to
the beaters, thereby dispensing entirely with the jacquard machine.

of Germany Manufacturer "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR
THE MANUFACTURE OF LACE AND OTHER LIKE ORNAMENTAL FABRICS APPLICABLE
ALSO TO THE MANUFACTURE OF ORNAMENTAL OR PLAIN BRAIDS

My said Invention relates to certain peculiar constructions arrangements and
combinations of machinery or apparatus capable of being driven by hand or by

the several figures on the explanatory sheets of drawings hereunto annexed the
same letters of reference indicating corresponding parts in all the figures.

line 33-34 in Figure 19. Figure 21 is an elevation of the mechanism for actuating.
the take-up rollers and Figure 22 is a transverse vertical section of a detail of the

My said improved machine consists of four principal parts working together to
produce the lace or other like ornamental fabric which parts are:-First, the
mechanism for actuating and guiding the bobbin carriers; Second the beaters and
mechanism for actuating the same; Third the take-up rollers in combination with
the needle mechanism for fixing the thread crossings pushed up. by the beaters
and for taking up the work thus produced; Fourth the jacquard or pattern
mechanism which controls the working of the apparatus comprised under the First
second and third parts of the machine.
The before mentioned four principal parts of the machine are fitted between two
pairs of upright standards connected together by cross bars so as to form the
general framing of the complete machine. These standards carry the driving
shaft B which actuates the mechanism for driving the bobbin carriers through the
mitre wheels at C, C, C, in combination with pinions disposed at an angle according
to the inclination in which the notched disc wheels are placed on their segmental
supporting plates (see figures 1 and 2). The making of a fixed guide plate for the
bobbin carriers in the form of an arc or segment of a circle disposed in a vertical
plane as in figures 1 and 2 constitutes one of the distinguishing features of my
improved machine.
I am aware that it has been proposed to arrange the bobbin carriers and their
driving mechanism in a segment of a circle placed horizontally but my arrangement
of bobbin carriers in a curved fixed guide plate disposed in a vertical plane admits
of the use of bobbin carriers and their accessories such as are employed in the
usual German Braiding machines whereby a quicker and more regular action with
fewer breakages of the threads can be obtained.
In my arrangement of the bobbin carriers it will be evident that the notched
discs with their driving wheels should he of a slightly conical form according to the
radius of the arc of the guiding plate. Although I have shown four rows of
notched disc wheels geared together in Figures 3 and 4 (each notched disc c having
two notches or propelling arms) it is obvious that the number of rows may be
increased or diminished, or a single row alone may be used. When using two
or more rows connected together I introduce between each two pairs of notched
disc wheels b, f a small standard h carrying two vertical rocking spindles & with
guiding fingers or directors i (see figures 3 and 4). In order to render the machine
capable of producing various different patterns of work I so arrange all the notched
disc wheels of the machine as to admit of the movement of the bobbin carriers
being arrested and started again as may be required by the action of jacquard
mechanism combination with springs controlling the notched discs for f¹. The
operation of the notched discs for arresting the bobbin carriers may be obtained in

page_text: various ways. All the notched disc wheels b, f, are mounted and turn freely upon
fixed pivots a permanently secured to the curved fixed bed plate of the machine.
In the arrangement shown at figures 4 and 5 the diameter of the pivot above the
wheel bis reduced so as to receive the collar d which carries the studs entering
inclined grooves in an outer collar e. The said pivots are moreover bored out
centrally to a certain distance to receive the rocking spindle a¹ and are formed with
two lateral or radial openings communicating with the upper part of the bore of the
pivot. Through the said lateral openings are passed studs or rivets which connect
the collar d with the rocking spindle a¹ in such a way that the collar shall rock
along with the said spindle the rocking of which is obtained by a jacquard machine
in connection with springs. As the collar d engages as above described with the
spiral or inclined slots or grooves in the collar e and as this collar e is prevented
from rotating by one or more guides g fixed on the pivot a in any convenient
manner it follows that the collar e will be caused to slide up or down on the collar
d by the rocking motion of the vertical spindle a'. The lower part of the guides g
also serve to keep the wheel b down in its proper place. The collar e is coupled to
the notched disc f by a projecting ring or shoulder on f which engages with suitable
grooves in the upper end of the collar e so that the notched disc f will be free to
rotate but must rise and fall along with the collar e. The notched disc f is forined
at its upper end with two opposite projecting arms so that when raised one or other
of the arms will be brought within the range of the lower end of the bobbin carrier
and by its motion will cause the bobbin carrier to travel but when the notched disc
f is lowered its projecting rotating arms will escape the lower end of the bobbin
carrier leaving it at rest. The rotary motion of the notched disc f is produced in
the following manner-On the boss of the driving wheel b there is fixed a collar c
carrying an upright finger which engages at its upper end with a slotted pro-
jection on the lower end of the notched disc f and carries it round along with it the
notched disc being free to slide up and down the said upright finger whilst the finger
also is free to turn round the collar e and its guide g. In the arrangement shown
at figures 6, 8, 9, and 10 the spiral or inclined grooves are made in the pivot a³ in
lieu of in a collar as before described. Into these grooves projects a transverse pin
or rivet carried by the rocking spindle a' and rivetted to the collar e¹ so that by
the rocking of the spindle a' the said spindle will be at the same time caused to
slide vertically and will consequently carry along with it the collar e¹. This collar
is coupled in the manner herein before described to an intermediate collar c¹ which
rises and falls along with the collar e¹ and is free to rotate such rotation being
produced by one or a pair of upright fingers c arranged as before described with
reference to figure 4. The upper end of the collar e' is provided with an upright
projection which engages with or becomes disengaged from lateral projections
formed on the lower part of the notched disc f₁ and causes it to rotate or not
according as the collar c' is raised or lowered. The notched disc f' in lieu of rising
and falling as in the previous arrangement rests upon a collar fixed to the pivot
u and its under projections correspond with the upper ones which drive the
bobbin carrier.
The lower part of the improved bobbin carrier shown in figures 6 and 7 is so
constructed as to ensure greater steadiness and stability to the said carrier in any
position upon its guide plate For this purpose I make one or both of the
supporting flanges of the bobbin carrier self-adjusting to the surface of the guide
plate by means of a spring or springs; in figures 6 and 7 I have shown the upper
flange only as self adjusting. The lower flange may be fitted to or formed on the
guiding part of the bobbin carrier in the usual way but the upper flange is free to
move up or down the guiding part of the bobbin carrier and is pressed downwards
by means of helical springs mounted upon vertical pins and pressing at their upper
ends against a fixed flange on the bobbin carrier there being sufficient play left
between the said fixed flange and the upper ends of the pins to allow of the self-
adjustment of the moveable flange.
This arrangement will also allow the bobbin carriers to adapt themselves to any.

page_text: slight irregularities in the curve of the guide plate and is equally applicable to a
flat guide plate. In the arrangement of notched disc wheel shown at figures 11
and 11 the mechanism for raising and lowering the notched disc is situate
outside the pivots in lieu of being centrally disposed. It consists of a forked
arm e² embracing the boss of the notched disc f' and raised or lowered by a
quick pitched screw thread on a vertical rocking spindle a³ which is actuated by
jacquard mechanism through suitable connections. The outer end of the arm e² is
guided by a fixed pin as shown along which it is free to slide up and down. It
will be understood that this arrangement is only applicable where not more than
two rows of notched disc wheels are used. The notched discs may either be in
one with or separate from the driving wheels but when made in one therewith the
breadth of the spur teeth should be sufficient to allow of the rising and falling of
the wheel without interfering with its engagement' with its adjoining driving
wheels. In figures 12 and 12" I have shown an external central arrangement
for raising and lowering the notched disc it consists of a hollow pivot through
which passes a rocking spindle a having a quick pitched screw thread at its
upper end upon which screw slides a travelling nut e³ having a vertical descending
arm on each side thereof. These arms pass through suitable guide openings in the
corresponding disc of the guide plate and bear upon the notched disc so as to press
it downwards or allow it to rise again by the action of the screw according as it is
turned in one direction or the other by the jacquard mechanism as will be readily
understood. It will also be readily understood from the arrangements hereinbefore
described for starting and arresting the motion of any one or more of the bobbin
carriers in combination with the guiding fingers or directors i governed by jacquard
mechanism that the course of the bobbin carriers can be governed at will and hence
it is desirable to push and fix the crossings of the threads up to the braiding point
at will and as required.
The arrangements for effecting this are represented in detail at figures 13 to 22
and consist generally of beaters for pushing the crossings towards the braiding
point further of two needlo mechanisms working independently the one from the
other and serving to fix temporarily the crossings and thirdly a system of take-
up rollers to take up the work as required.
The beaters K are actuated or driven from the first motion shaft B gearing with
the vertical shaft D which rotates at double the speed of the shaft B and drives
the jacquard machine X as well as the horizontal shaft E. This shaft E drives
through mitre wheels the short spindle F carrying the crank F' which imparts the
up-and-down motion to the vertical slide G guided in the frame H (see figures 13,
14 and 15). This slide is provided with two holders G₁ which carry the lifter
bar G² to which are fitted the guide pins 7 sliding freely through bosses in the
holders G¹ so that the lifter bar though constantly pressed upwards by helical
springs is free to yield or descend slightly when pressed downwards. The lifter
bar G² moves up and down along with the slide G and is intended to actuate the
beaters proper K which are mounted freely on the guide rails J disposed radially
from below the braiding point towards the notched disc wheels. These guide
rails at their lower ends rest upon and are attached to a cross bar fixed to the
supporting frame L' whilst their upper ends are attached to the supports L both
which supports are attached in any suitable manner to the main upright
standards A. At their lower ends these guide rails J are maintained at the
required distance one from the other by intermediate pieces m whilst at their upper
ends they are capable of being adjusted nearer together or farther apart (according
to the fineness of the work to be produced) by the aid of moveable intermediate
washers or otherwise. Each beater consists of a hollow slide n of the form shown
in figure 16 which embraces and is free to slide along the guide rail J. To the
lower part of this slide and on the side towards the work there is hinged or
pivotted the moveable beater arm proper n' which in its position of rest is retained
by the cross bar r fixed to the framing L'. On the opposite side of the said slide
there is hinged or pivotted a vertical hooked lever o. The upper end of the said

page_text: The
slide is prolonged and has hinged thereto a bent lever q. In order that the beaters
may be capable of being worked or left at rest as required there is provided a
lever o' (one for each beater) mounted on a horizontal spindle and actuated
as required by jacquard mechanism and suitable connections. The levers o'
belonging to those beaters which are to be lifted by the lifter bar G² in order
to push up their corresponding crossings to the braiding point are drawn
away from the hooked levers o by the action of the jacquard machine the
said levers o having been previously pressed towards the rails J and out
of the range of the lifter bar G2 by the upper ends of the levers o¹.
result then is that the levers o take their opposite extreme position (shown
at figure 16) by the action of a spring and their hooks are brought over the
edge of the said lifter bar G². This bar when at its lowest position is free to play
in the space between the hook of the lever o and the projecting portion of the
lower edge of the slide n. In this position it will be readily understood that
the slide n will be lifted by the bar G2 during the rising motion of the slide G
and will allow the beater proper n¹ on leaving the cross bar to be pushed inwards
towards the range of threads by a spring to its full range limited only by the upper
front part of the slide n in which position the head of the beater proper n' will be
brought between the corresponding crossing of the threads and will push such
crossings by its continued ascent towards the braiding point. Shortly before
reaching the braiding point a selfacting spring-jointed catch lever forming part of
the bell crank lever q comes in contact with a stop q' fixed to the guide rail J but
as this catch is hinged by a spring joint so as to yield to any downward pressure
thereon it passes such stop freely. The beaters proper are so adjusted as that when
in their highest position their heads will be in one and the same line such position
being attained slightly before the slide G has arrived at its highest position for
during the completion of the upward motion of the slide the lifter bar G³ yields (as
herein before described) under the pressure of the two fixed studs 21 attached to a
cross bar z fixed to the framing and thus maintains its position as well as that of
the beaters K whilst the slide G completes its upward motion. The lifter bar G²
having been arrested by its contact with the studs 21 (see figure 2) retains this
position until the slide G in its descent arrives at the corresponding position where
the lifter G2 first encountered the studs ¹ when it will be drawn down along with
the slide G and will draw down with it the beaters K that had been lifted by
pressing against the projection on the beater slide n opposite the hook of the
lever o.

It will be obvious from what has been above described that the beaters will
have a certain pause or dwell at the termination of "their upward stroke the object
of which I shall hereinafter describe.
As the beater descends the before mentioned spring catch of the bell crank
lever q encounters the stop or fixed pin q' in the guide rail and as it is rigid in its
downward movement it causes the longer arm of the bell crank g to strike against
a stud in the beater arın n¹ and draws it towards the guide rail J and away from
the range of threads in which position it is maintained locked by a spring catch p
at the lower end of the slide n (as shown in figure 16) until the said catch p
encounters a corresponding projection formed on each of the before mentioned
distance pieces m between the rails J whereupon the beater arm n¹ is released (sec
figure 13) and allowed to take its position when at rest against the bar r. If the
beater K be not required to be lifted again the corresponding lever o¹ will have
been allowed by the jacquard machine to move back to its original position towards
the rails J in time to operate upon the inclined lower end of the hooked lever o
which in its descent slides against the head of the lever o' and the hook of the
lever o will thereby be removed out of the range of the lifter bar G³ the corre-
sponding beater being thus allowed to remain at rest as long as may be required.
As the upper part of the hooks of the levers o is inclined the lifter bar on its
descent will readily engage itself under the hooks of such levers o as have been
again brought into position for lifting their beaters as before described.

page_text: In figure 17 I have shown a slight modification of the catch p which is here
represented as a notched flat spring p' fixed to the lower end of the beater proper n
in lieu of being a hinged catch as in figure 16. The crossings of the threads having
been pushed up to the braiding point as described must be there secured and
delivered to the take-up rollers in such a manner that the work shall not suffer
any contortion or other derangement.
The arrangement which I employ for this purpose consists of two systems
of take-up rollers Q and Q¹ and of two needle mechanisms R the whole being
controlled by jacquard mechanism and mounted on a slide M. supported by
cross bars V secured to the columns A A of the main framing as shown at
figures 1 and 2 and in detail at figures 18 to 22. This slide is free to travel to-
and-fro (by the action of a jacquard mechanism) along the said cross bars with a
view to facilitating the imitation of that kind of hand made lace which is produced
by the aid of bobbins as this class of lace frequently requires that parts of the
fabric shall be worked at certain times closer together (in a lateral direction) or
further apart than at other times. The take-up rollers as well as their accessory
parts are driven from the horizontal shaft N which derives its motion from the
vertical shaft D by mitre wheels. On the shaft N there is mounted by a slot and
feather arrangement a longitudinally sliding tubular shafts which rotates along
with the shaft N. This tubular shaft a carries the whole of the gearing requisite
for actuating the take-up rollers and the needle mechanism and is carried along
with its supporting shaft N in suitable bearings mounted on the slide M the said
tubular shaft being fitted with adjustable collars on each side of the said bearings
so as to ensure the longitudinal movement of the said shafts along with the
slide M (see figures 18 and 19). The two systems of take up rollers Q Q' are
driven from the said tubular shaft by the vertical spindle P and suitable bevel gear
which transmit motion to the horizontal axis P' and thence to the vertical spindle P²
carrying endless screws or worms which gear into worm wheels on the axis of one
of the take-up rollers in each system. The arrangement of the two systems of
rollers QQ is such that the system Q can be thrown out of action whilst the
system Q' continues to take up the work as it is produced the object of this and
the mode of carrying it into effect being fully explained in the specification to my
Patent Dated July 12th 1880 N° 2864.
In my present arrangement I control the motion of the system Q of take-up
rollers by a clutch arrangement on the axis P governed or controlled by jacquard
mechanism and I effect the bringing together and separation of the rollers of the
system Q by an arrangement of toggle jointed levers connected through the link t'
to a bell crank lever t2 (see figures 18, 20 and 21) the entire system of take-up
rollers and their accessories being carried by suitable supports attached to the
slide M. The needle mechanism is driven by two groups of mitre or bevel reversing
gear u umounted loose upon the tubular shafts and gearing with the bevel
wheels u which will be driven in one or the other direction according as one or the
other of the corresponding sliding clutches on the tubular shaft 8 is brought into or
out of action by the usual clutch actuating mechanism which I control or govern
by jacquard mechanism (see figures 18 and 19). On the opposite ends of the
spindles which carry the wheels u, are mounted the bevel or mitre wheels u³ which
drive the vertical spindles vv at the same speed as the tubular shaft s.
vertical spindles vv transmit motion to their corresponding vertical spindles vi v¹
by spur wheels gearing into corresponding spur wheels loose upon the spindles v¹.
I have shown in my drawings three sets of spur wheels so arranged as to give three
different speeds to the spindles v' with which the loose spur wheels are coupled by
the usual clutch arrangement governed by jacquard mechanism. The rotation of
the spindles vis transmitted by intermediate or carrier wheels w to the vertical
screw spindles xx working in footstep bearings and gearing into the travelling
nuts carrying each a cross bar which bars are fixed by set screws to
the vertical sliding rods guided by lugs or projections on the supporting
frame of the take-up rollers. At the lower end of each pair of vertical rods ² there is
The

page_text: mounted one of the needle mechanisms R which are consequently moved up or down
according to the direction in which the screw spindles a are rotated. Each needle
mechanism is provided with the needles y which are disposed in a straight
horizontal row and guided between upper and lower guide plates (see enlarged
detail Figure 22). The distance between the needles depends upon the fineness of
the work to be produced and therefore I prefer to make the needle mechanisın
readily removeable from the rods so as to be replaced by others of different
gauge. Each needle is connected with a corresponding lever which keeps it always
in its outward position by the action of spring pushers and is withdrawn by
jacquard mechanism by the aid of suitable connectors passing through the
perforated plate W attached to the slide M (see figures 1, 2 and 20). It will be
understood from the description of the driving gear of the needle mechanism R
that the vertical movements of the said two mechanisins are also independent of
each other and may take place alternately. When it is required to fix the crossings
of the threads brought up by the beaters as herein before described one of the needle
mechanisms R is lowered so as to bring its range of needles (which at this moment
are kept withdrawn by the Jacquard) to the position to which the beaters have
brought the crossings or meshes and such of the needles as may be required are
then allowed to move outwards and enter the corresponding crossings or meshes by
the action of their springs, the pause or dwell in the movement of the beaters K
herein before described affording sufficient time for the needles to enter. In order
to facilitate the engagement of the needles with the said crossings or meshes I
either form the head of the beater with a groove in a line with its corresponding
needle into which grooves the needlo enters when pushed forward; or I provide the
head of the beater with a number of bristles or their equivalent disposed close
together longitudinally and in a line with the corresponding needle in such
manner as to allow of the needles penetrating the bundle of bristles and engaging
with the crossings or meshes which are then left on the needles by the beaters
in their descent. On the completion of the row of meshes in the same line which
I will call the first row the range of needles is lifted to the braiding point situate
just below the take-up rollers Q and coincident with the centre of the arc or
segment of the slotted guide plate, and the second frame of needles R which is
opposed to the first is now caused to descend and take the next or second row of
meshes in the same manner as previously described it then rises and brings this
row into the proper relative position (according to the fineness of the work to be
produced) to the previous or first row of meshes the second fow being thus
sustained by its needles ensures also the stability of the first row from which the
needles are now withdrawn and caused to descend with their frame and mechanism R
to take up a third row of meshes as before described. During this latter action
the take-up rollers QQ which have been at rest since the taking up of the first
row now commence to rotate in order to take up the work and bring the second
row into the position previously occupied by the first row the range of the needles
of the second row rising along with the work and at the same rate thus main-
taining or preserving the meshes intervening between the take-up rollers Q' and
these meshes. The second row of meshes having thus reached the previous position
of the first row the rotation of the take-up rollers QQ¹ as well as the lifting
motion of the said range of needles ceases and the operations are repeated for the
third row and so on as before described.
• When I require to make at certain times parts of the work closer together
laterally or further apart than at other times it becomes necessary that the take up
rollers as well as the needle mechanism shall move laterally in either direction and
to any extent required for it will be understood that as the beaters K always push
up the crossings to a given point such crossings will be fixed at a different lateral
position to the previous ones when in the meantime the take-up rollers in
combination with the needle mechanism have changed their lateral position. For
this purpose the frame which carries the take-up rollers and needle mechanism is
fixed-to the slide M which is formed with a nut engaging with a screw thread on

page_text: the shaft T. This shaft is rotated in either direction by suitably arranged gearing
from the shaft N which revolves in one direction only and may therefore either
transinit its motion through the intermediate shaft S directly or indirectly by
intermediate gearing so as to rotate the shaft T in the direction required. This
change of motion is effected by. a sliding clutch (see figure 18) worked by a lever
on a rocking shaft the movement of which is produced and governed by a jacquard
machine. The intermediate shaft S, transmits its motion to the scrow. shaft T by
different sets of spur gearing which ensure different speeds and consequently
different ranges of motion in the slide M and these different sets of gearing are
separately brought into action as required by clutches governed by jacquard
mechanism. In order to compensate for any slight variation in the distance
between any of the before mentioned sliding parts (whether sliding vertically or
horizontally) and the jacquard machine or the guide for the connectors I introduce
belical springs or other yielding couplings of suitable resistance into the cords or
other connectors. The jacquard or pattern governing or controlling mechanism
which I prefer to employ for controlling the various parts of my machine as
herein before described is that for which I obtained Letters Patent bearing date
June 13th N° 2568 A.D 1881.
The herein before described Lace making machine baving a fixed slotted guide
plate curved in a vertical plane for the bobbin carriers to slide along the centre of
the arc or segment formed by such slotted guide plate coinciding with the braiding
point of the machine, may be advantageously employed in the manufacture of plain
or ornamental braids by substituting for the hereinbefore described arrangements
of notched disc wheels having two notches or propelling arms the ordinary
arrangement of notched disc wheels as employed in the usual German braiding
machines in combination with beaters having a regular to-and-fro movement and
with the ordinary arrangement of take-up rollers thus dispensing with the
needle mechanism and the use of a jacquard machine or pattern governing
apparatus.
Having now described and particularly ascertained the nature of my said
invention and the manner in which the same is or may be used or carried into
effect I would observe in conclusion that what I consider to be novel and original
