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 consists partly of a new arrangement of one of the principal parts
in the lace or braid making machine described in the Specification to Letters
Patent granted to me the 14th July A.D. 1882 N° 3357 and partly of the com-
bination in one and the same machine along with the said improvements of the
peculiar apparatus described in the Specification to my patent N° 2568 A.D. 1881
for governing or regulating the pattern of the work produced and also the
combination therewith of the apparatus described in the Specification to my patent
No 2441 A.D. 1883 for pushing the crossings of the threads up to the braiding
point by which improvements and combinations I obtain a lace machine capable
of producing the lace in a more perfect and expeditious manner than has heretofore
been found practicable which machine may be used if desired for the making of
plain and ornamental braids.
The lace machine described in the Specification to my said patent N° 3357
A.D. 1882 effects the traverse of the bobbin carriers along the guide plate somewhat
after the manner of an ordinary braid machine and like that machine it possesses
also the characteristic feature that for obtaining the required interlacing of the
threads the bobbins can only cross one by one during their passage from one
position to another thereby requiring much time for the formation of a given piece
of the said lace wherein a woven ground is to be produced for which purpose the

page_text: thread of a bobbin forming the Weft must necessarily be passed alternately over
and under a great number of other threads forming the Warp. This objection is
completely obviated by my present improved lace machine since by reason of its
peculiar construction and combination of parts it enables any number of bobbin
carriers to pass at the same time (that is to say during one position) between any
number of other bobbin carriers like the shuttle of an ordinary loom and thus
renders the production of lace by this action of the bobbin carriers (which could
only be effected very slowly in the machine before referred to) nearly as expeditiously
as the manufacture of woven fabrics in an ordinary loom.
The frame of my present improved lace machine is by preference composed of
two side standards two intermediate standards and two back standards all
conveniently connected by cross bars or tie rods. In the lower part of this frame
are supports in the form of an arc the outer parts of which are fixed to the side
standards whilst the middle portions may be mounted on feet or bolted to the floor.
To the arc shaped supports are fitted radial plates or wings which carry between
them the mechanism for imparting the traversing movement to the bobbins and
which mechanism is driven through a series of short spindles carried in brackets
or pedestals fixed to the arc shaped supports. These spindles are connected
together by double universal joints and receive their movement from the main
driving shaft of the machine.
The actuating mechanism of the bobbin carriers is arranged as follows:-
The bobbin carriers whilst at work will be found in one or other of three
grooved or slotted guide plates which form part of a cylindrical surface the
geometrical axis of which is situate horizontally and at right angles to the main
driving shaft of the machine.
Two of the said three slotted guide plates are fixed and are situate outside
having between them a middle guide plate attached to a moveable bed, the
combination of which three guide plates constitutes the complete guides for the
bobbin carriers of the machine.
For this purpose each of the two fixed plates is at its upper part formed into a
series of tongues which leave cuts slots or grooves between them in which the
spindles or bobbin carriers slide as in the guide grooves of ordinary braid machines
constructed on what is known as the "German System."
These tongues terminate in points at their front ends directed towards the
moveable bed in such a manner that a core or centre piece disposed conveniently
between the points of two neighbouring tongues produces a bifurcation of said
grooves. These cores are mounted on arms attached to the outer fixed guide plates
and form a a part thereof.
As already mentioned there is disposed between the two fixed guide plates a
moveable bed which carries small middle guide plates forming grooves between
them corresponding to the grooves in the two fixed outer guide plates in such a
manner that the bobbin carriers can be pushed across to and fro from one of the
outer fixed guide plates to the other and consequently traversing the guiding grooves
or slots of the middle moveable guide plate. In order to regulate at will the
traverse of the bobbin carriers along the said grooves it is necessary on the one
part to employ directors or fingers carried on the tongues of the fixed guide plates
and suitably governed or controlled by convenient actuating mechanism and also
to employ automatic directors or fingers mounted on the before mentioned cores.
As the bobbin carriers always move towards the points of the directors which are
governed by actuating mechanism it is easily understood that a simple displace-
ment of such directors will conduct the bobbin carriers at will into one or the other
branch of the bifurcated grooves.
The automatic directors are shifted by the bobbin carriers themselves during
their passage from one fixed guide plate to the other and resume their original
positions under the action of a spring. These automatic directors prevent the
bobbin carriers from returning along the exit grooves and consequently they ensure
the continuity of their progress or course,

page_text: This arrangement allows the bobbin carriers to be advanced in the longitudinal
direction of the guide plates by suitably displacing or adjusting the directors and
by imparting only a simple to and fro motion to the actuators of the bobbin carriers
in a transverse direction as hereinafter explained.
The bobbin carrier driving or actuating mechanism hereinafter described in
combination with the slotted or grooved guide plates further admits of the starting
and stopping of the bobbin carriers and consequently then advance in one or the
other direction as required in the production of the lace.
In my improved lace machine the bobbin carriers can be equally well arrested
on either of the two fixed guide plates or on the intermediate moveable guide plate
and as this last is so arranged as to allow it to be displaced at will longitudinally
in the manner hereinafter explained it will be understood that the threads can be
interlaced at will to produce such classes of lace work as have been made
hitherto by hand as for example real Torchon lace real Valenciennes lace and
the like
The mechanism for producing the transverse traverse of the bobbin carriers is
actuated by the before mentioned short spindles connected together by universal
joints and which for this purpose carry cams communicating a to and fro movement.
to a slide by means of levers mounted on a rocking shaft.
It is this slide which serves to impart motion to the various bobbin carrier
actuating mechanisms and as it is required to actuate a number of these at one
time it is furnished with a shaft disposed in a curved line towards the interior or
in the form of an arc to which shaft are jointed the rods or connectors of the
different mechanisms each rod actuating a like mechanism the number of which
corresponds to the number of guide grooves of the lace machine
According to the most simple of the bobbin carrier actuating mechanisms and
which I will first describe the before mentioned connector actuates a vibrating
slotted link formed somewhat similar to the link of the well known slide valve
motion of a steam engine within which link slides in two directions the slide block
of a connecting rod. The said slotted link vibrates on a centre or pivot in a
bearing fitted to a fixed bracket or part of the framing. The arrangement of the
slotted link is such as to allow the movement of the slide block without
impediment as far as the geometrical axis of vibration of the link-This link is
curved to the arc of a circle in such a manner that the slide block can further bo
brought into two other positions beyond that of the said geometrical axis of
vibration of the link. The connecting rod or bar actuates in its turn a lever
suitably guided by means of which a horizontal sliding bar which gives the
transverse traverse motion to the bobbin carriers can be alternately moved in one
direction or the other. This sliding bar is provided with a fork which embraces
a pin fixed to the lower end of the bobbin carrier which pin (hereinafter called
the "foot of the bobbin carrier") is not rounded as in the bobbin carriers of
ordinary braid machines but is of a flattened rectangular section having its larger
dimension placed perpendicularly or crosswise to the guide groove.
Below each slot or groove of the moveable bed or guide plate there is fitted one
of these horizontal sliding bars the connecting fork of which is as wide as the
distance between two arms carrying the core pieces with the automatic fingers in
the guide plate will admit, this width of the fork allows the latter to embrace the
foot of the bobbin carrier even when in position on one of the fixed guide plates
and it must be understood that thus each fork will always command in each of the
two fixed slotted guide plates two grooves corresponding with the grooves in the
moveable guide plate and that therefore each of the guide grooves of the two fixed
guide plates has at its disposal two sliding bars with their forks for moving the
bobbin carriers.
In order that the movements of the bobbin carriers in two adjoining grooves or
slots of the moveable guide plate may be in opposite directions as required for the
interlacing of the threads it follows that their actuating horizontal sliding bars
should only move the bobbin carriers in the direction required by their course,
5

page_text: But as the movements of the bobbin carriers in the transverse direction should be
effected simultaneously in order to economise time the movement of the two
adjoining sliding bars should also be in opposite directions
This result is obtained by joining the beforementioned connecting rod of one
of the slotted vibrating links to the said link at a point situate below the centre
of vibration of such link and connecting the rod of the neighbouring link at a point
situate above its centre of vibration
It also results from what has been above stated that each horizontal sliding bar
should pause during its backward movement and that the fork of this bar should
be disengaged or uncoupled from the foot of the bobbin carrier after having moved
the bobbin carrier into the desired position which disengagement is effected by
lowering the said horizontal sliding bar.
To this end each of the sliding bars is guided between antifriction rollers
mounted in upright suspended bars which are raised and lowered as required by
lever arms and a coupling rod.
One of the levers of the upright suspended bars is connected in any well known
manner with a governing or controlling mechanism which effects as required the
lowering of the upright suspended bars and consequently the disengagement of the
fork of the horizontal sliding bar whilst a spring effects the raising of the same
and consequently the re-engagement of the fork with the foot of the bobbin carrier
and vice versa.
Any of the well known controlling or governing mechanisms used in lace
machines may obviously be applied to the above purpose.
During the period of its return or back traverse the sliding bar remains lowered
and only engages afresh with the foot of the bobbin carrier during the change of
movement of its actuating lever the curve of the cam which works the said lever
being of such a form as to cause the lever to pause or dwell a short time at each
change in the direction of motion. The bobbin carriers should be capable of being
placed in position either upon one or the other of the two fixed guide plates as
also upon the moveable guide plate. Besides these three positions the before
described arrangement allows of another position upon each of the fixed guide
plates with a view to admit of the placing of bobbin carriers in reserve when
necessary. These five positions of the horizontal sliding bar necessitate three
positions of the slide block in the slotted vibrating link which are effected by
raising and lowering a vertical guide bar embracing the sliding connecting rod of
the slide block.
For this purpose the said vertical guide bar is connected at its lower part to a
lever arm which is maintained in its extreme elevated position by a spring and
thereby ensures also the extreme elevated position of the slide block in its slotted
link. This lever is provided with two adjustable regulating slotted links each of
which is connected to a suitable controlling or governing mechanism. The extreme
upper position of the said lever is assured by the engagement of these links with
studs or pins fixed in the framing and a regulating screw by means of which the
downward movement of the lever is limited. By drawing the outer regulating
link the slide block is brought into its middle position and on drawing the inner
regulating link the slide block will be brought into a position to coincide with the
axis of vibration of the before mentioned vibrating slotted link. This last
position of the slide block corresponds to the position of the bobbin carriers on the
moveable slotted guide plate, the middle position of the slide block corresponds to
what I have hereinafter called the inner or "internal position" of the bobbin
carriers on the two fixed slotted guide plates and the upper position of the slide
block corresponds to what I have hereinafter called the outer or " external
position" of the bottom carriers on the said fixed guide plates. The commencement
of each new position takes place during the movement of the slotted vibrating link.
During their traverse the bobbin carriers are guided in the ordinary manner by
means of moveable directors or fingers which are connected to a controlling or
governing apparatus.

page_text: On the axis of each finger is mounted a small lever which is connected by any
suitable connector (guided by guide rollers) with a controlling or governing
apparatus.
According to another modification of the arrangement for determining the
traverse of the bobbin carriers transversely to the fixed and moveable slotted guide
plates the slide block requires only two positions in the vibrating slotted link in
order to bring the bobbin carriers into all their required positions but in this case
it is necessary that the beforementioned horizontal sliding bar be provided with
two engaging forks and that the moveable slotted guide plates should be wide enough
to enable the bobbin carriers to take up two positions on the said moveable
guide plate.
Moreover all the positions of the bobbin carriers on the three slotted guide
plates should be situated at exactly the same distance from each other which
distance must correspond with the distance between the two engaging forks on
the horizontal slide bar.
"
These arrangements allow according as one or other of the two engaging
forks is used (in combination with the placing in suitable position of the respective
slide block within its vibrating slotted link) of giving to the bobbin carriers the
position which I have called the "internal position on each of the fixed slotted
guide plates as well as the second or "external position" on the same guide plate
so as to hold certain bobbin carriers in reserve just as in the arrangement
herein before (first) described. But in the present case the placing of the bobbin
carriers in the "external position" alternates in the guide grooves in such a
manner that the fixed guide plate of the one side allows only of this displacement
in the even numbers of its grooves or slots whilst the fixed guide plate of the
other side allows such displacement only in the odd numbers of its grooves
or slots.
The movements of the moveable bed or guide plate takes place during certain
periods of rest in the transverse movements of the bobbin carriers for which object
the actuating cam is of such a form that at each revolution the horizontal sliding
bars make in addition to two direct movements (for the displacement of the bobbin
carriers) two inverse movements and as they will be found during these latter
movements in their lowest positions two periods of repose will result at each
rotation of the cams which may be utilized for effecting the displacement of the
moveable bed or guide plate. It is evident that the lowering of the horizontal
sliding bars should be sufficient to allow of free play to the said moveable guide
plate.
The moveable bed or guide plate is composed of a series of slides connected by
means of pins or bolts and the bottom of each slide is arranged in the form of a
grate which allows a free passage of the engaging forks of the beforementioned
horizontal slide bars when in operation between the grate bars.
Each of these slides rests by four rollers in suitable guides which are joined to
the radial wings previously mentioned the guides being prolonged on both sides
sufficient to allow of the desired displacement of the moveable bed or guide plate.
This latter passes in its turn the fixed guide plates on both sides for the same
reason, and a certain number of the slides which are at the end of the moveable
bed are furnished on both their lateral faces with coupling or driving pins placed
at distances corresponding to the distances between the guide grooves.
The actuating of the moveable bed is effected by two special and similar
arrangements of mechanism one of which is disposed on each side of the machine so
that the movement of the bed towards the left shall be effected by the left hand
mechanism and towards the right by the right hand mechanism.
Each time that one of these actuating mechanisms is required to operate it is
coupled with the moveable bed by means of a governing or controlling apparatus
and can then effect the displacement of the said bed to the required extent.
The putting of this mechanism into action is effected through a vertical shaft
driven from the main horizontal driving or first motion shaft of the machine.

page_text: The said vertical shaft actuates through bevel gear a short horizontal shaft
which carries a cam making a number of turns equal to those of the before
mentioned cam which actuates the horizontal slide for traversing the bobbin
carriers. This cam imparts a continuous oscillating or vibrating movement to a
slotted link mounted on a stationary axis whilst the said vibrating link actuates
through a connecting rod a short lever arm on a horizontal rocking shaft carrying
also radial lever arms which can be suitably connected at their outer or free ends
with the beforementioned moveable bed or guide plate.
This connection of the radial lever arins with the said moveable bed may be
effected through the engagement of adjustable sliding forked pieces on such arms
engaging with the beforementioned driving pins or bolts in the said bed.
For this purpose the said sliding forked pieces can be moved along their radial
lever arms and engaged as required by bell crank levers and a controlling or
governing mechanism. These bell cranks rest in stirrups fixed to the radial levers
and engage with sliding collars on the horizontal shaft
Provision is made for regulating as required the amount of displacement of the
moveable bed by varying the position of the end of the connecting rod in the
vibrating slotted link which may be effected by a regulating sliding bar which
guides the said connecting rod along the slot by means of antifriction rollers. The
regulating sliding bar is connected to the lower end of a lever mounted on an axle
on which are carried freely other levers connected with a governing mechanism.
On pulling one of this range or series of levers say the shortest one a stirrup fixed
on the axle which carries the said levers is engaged and caused to move that axle
along with its vertical vibrating lever. Now the levers of the range being of
different lengths it is sufficient to actuate one or the other of them in order to vary
proportionately the movement of the vertical lever and consequently the position
of the end of the connecting rod in the slotted link. The said vertical lever is
disposed in such a manner as to be disengaged from the sliding regulating bar so
as to allow to this last the horizontal movement that it should make during the
working of the vibrating slotted link in accordance with the position of the slide
block therein.
For this object the said vertical lever slides on a tongue or feather on its axis
and it is disengaged during the operation of the slotted link by a cam or finger
which acts on it by means of special levers.
The fixing in proper position of the slide block in the slotted link has for its
object the allowing of the placing into exact position of the moveable bed and this
fixing is obtained by providing the slide block with a tooth capable of engaging in
a rack the teeth of which should correspond in position and number to the required
amount and number of the movements of the moveable bed. This rack guided as
it is on guide pins fixed to the slotted link is hung to bell crank levers connected
by a coupling bar and can be engaged and disengaged by means of tappets on the
cam which actuates one of the said bell crank levers. The engagement is effected
directly after the adjustment of the connecting rod by the vertical lever, that is to
say towards the end of the pause of the slotted link. The adjustment of the
position of the slide block in the slotted link having been effected the link
immediately commences its descent and maintains the slide block in place till it
again returns to its position of repose.
It is at the moment when the slotted link completes its ascent that the
disengagement of the rack takes place at the same time as the engagement of the
vertical lever connected with the before mentioned sliding regulating bar.
As each of the above described mechanisms only effects the movement of the
moveable bed in one direction as before stated it follows that the adjustable forks
of the radial levers should be disengaged during their return. This disengagement
takes place immediately after the completion of the movement of the moveable bed
and at the same time the engagement of another or stop mechanism is effected in
order to maintain the moveable bed in its new position and ensure the exactness
thereof.

page_text: The bringing into action of this last mentioned mechanism is effected by one of
the series of short spindles carried on the arc shaped supports previously referred
to. This spindle carries a moveable cam which acts upon a bell crank and through
it and a connecting rod and lever imparts motion to a rock shaft.
On this shaft are mounted two levers which move the arresting teeth in their
guides and these teeth by entering during their descent between two of the
engaging pins or bolts of the moveable bed determine and ensure its being placed
in exact position.
When the moveable bed is to be fixed for a greater or less time then the cam last
referred to is moved together with the bell crank lever which is connected with a
controlling or governing mechanisn. Thus the stop tooth can remain in its place
as long as the work requires.
To effect the pushing of the crossings of the interlaced threads towards the
braiding point the arrangement of beaters described in the specification to my
patent No 2441 A.D. 1883 is employed and is actuated by the before mentioned
vertical shaft by means of two other horizontal shafts driven therefrom by bevel
gear
Further the fixing of the crossings and the taking up of the work as it is
produced is effected by means of the needle mechanism and take up rollers described
in the specification to my patent No 3357 A.D. 1882.
This mechanism is driven from one of the last mentioned horizontal shafts and
an additional short vertical shaft all geared together.
Finally the pattern governing or controlling mechanism in my present improved
lace machine may be similar to that described in the Specification to my patent
No 2568 A.D. 1881, and may be driven directly from the principal or first notion
shaft of the machine.
The connection of the various parts of the machine with the governing or
controlling mechanism is effected by the aid of cords chains or metal wire guided
where required by means of rollers levers or other suitable and well known
mechanical appliances.

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 "
My said Invention relates to certain peculiar constructions arrangements and com-
binations of mechanism constituting a new or improved machine to be employed in
the manufacture of Lace and other like ornamental fabrics and of plain or ornamental
braids and consists partly of a novel arrangement (hereinafter described) of one of
the principal parts of the lace or braid making machine specified under my Patent
N°3357 A.D. 1882, for effecting the guiding and traversing of the bobbin carriers,
and partly in the combination together in a lace or braid making machine of the
said novel arrangement for guiding and traversing the bobbin carriers with any
one or more of the following arrangements namely; the peculiar mechanism for
pushing the crossings or interlacements of the threads towards the braiding point,
described in the specification to my patent N° 2441 A.D. 1883-the peculiar
combined needle mechanism and "Take-up" rolles for fixing the crossings and
taking up the work as fast as it is produced, (also described in the specification to
my said patent N° 3357 A.D. 1882) and the peculiar arrangement of pattern-
regulating or governing mechanism described in the specification to my patent
No 2568 A.D. 1881 for actuating and controlling such parts of my improved
machine as have to be governed by a Jacquard or other pattern governing
mechanism in order to effect the required variations of pattern in the work
produced by which improvements and combinations I am enabled to produce
Lace work by machinery in a more perfect and expeditious manner than has
heretofore been found practicable.
In the lace making machine described in the specification to my said patent
No 3357 A.D. 1882 the traverse of the bobbin carriers along the guide plate is
effected somewhat after the manner of an ordinary braid machine and like that
machine it possesses the following characteristic feature namely that in effecting the
required interlacement of the threads the bobbins can only cross one by one
during their passage from one position to another hence the production in the said
machine of the class of lace wherein a woven ground is to be formed in which the
thread of a bobbin forming the weft must necessarily be passed alternately over
and under a number of other threads forming the warp is comparatively slow.
This objection is completely obviated by my present improved lace machine since
by reason of the peculiar construction arrangement and combination of its parts it
enables any number of bobbin carriers to pass at the same time (that is to say
during one position) between any number of other bobbin carriers like the shuttle
of an crdinary loom and thus renders the production of lace by this action of the
bobbin carriers nearly as expeditious as the manufacture of woven fabrics in an
ordinary loom.
And in order that my said invention may be fully understood I shall now
proceed more particularly to describe the same and for that purpose shall refer to
the several figures on the explanatory sheets of drawings hereunto annexed the
same letters of reference indicating corresponding parts in all the figures.

Figure 18 is a corresponding side view thereof.
In figures 1 to 3 the leading or essential parts only are shown in order that they
may be more readily understood and the small accessory parts which would have
rendered the drawings indistinct have been suppressed and form the subject of
special details.
As shown in figures 1 to 3 the frame of my present improved lace machine is by
preference composed of two side standards F F the intermediate standards H and
the back standards G suitably connected by cross bars or tie rods. In the lower
part of this frame are supports D in the form of an arc the outer ends of which are
fixed to the side standards F F whilst the middle portions are mounted on feet
resting on plates bolted to the floor. To the arc shaped supports D are fitted
radial plates or wings E which carry between them the mechanism for imparting
the traversing movement to the bobbin carriers which mechanism is driven by a
series of short spindles B carried in brackets or pedestals C also fixed to the arc
shaped supports D. These spindles B are connected together by double universal
joints and are driven from the main driving shaft A of the machine.
The actuating mechanism of the bobbin carriers is arranged as follows:-
The bobbin carriers whilst at work will be found in one or other of the plates
Q, Q, R, which form part of a cylindrical surface the axis of which is situate
horizontally above and at right angles to the main driving shaft A. of the machine
as shown clearly in figure 1. Two of the slotted guide plates QQ are fixed and
are situate outside and have between them a mid lle guide plate m (or m figures
7 to 11) attached to a moveable bed R the combination of which three guide plates
constitutes the complete guides for the bobbin carriers of the machine.
For this purpose each of the two fixed plates QQ is on its upper surface formed
into a series of tongues i having slots or grooves between them in which the
spindles or bobbin carriers slide as in the guide grooves of ordinary braid machines
constructed on what is known as the "German System."
The tongues i terminate in points at their front ends directed towards the
moveable bed R (or R' figures 7 to 11) in such a manner that a core or centre
piece k disposed conveniently between the points of two neighbouring tongues i

page_text: produces a bifurcation of said grooves. These cores are mounted on arms k¹
attached to the outer fixed guide plates and forming a part thereof.
As already mentioned there is disposed between the two fixed guide plates Q a
moveable plate or bed R (or R2 figures 7 to 11) which carries small middle guide
plates m (or m³) forming grooves between them corresponding to the grooves in the
two fixed outer guide plates in such a manner that the bobbin carriers can be
pushed across to-and-fro from one of the outer fixed guide plates Q to the other
and consequently traverse the guiding grooves or slots of the middle moveable
guide plate. In order to regulate at will the traverse of the bobbin carriers along
the said grooves it is necessary to employ on the one part directors or fingers ¿¹
carried on the tongues i of the fixed guide plates Q and suitably governed or
controlled by Jacquard or other convenient pattern regulating mechanism, also on
the other part to employ automatic directors or fingers 2 mounted on the before
mentioned cores k (figures 10 and 11).
As the bobbin carriers always move towards the points of the directors i¹ which
are governed or controlled by pattern mechanism (by preference of the kind
described in the specification to my Patent N° 2568 A.D. 1881) it is easily
understood that a simple displacement of such directors by the said mechanism will
conduct the bobbin carriers at will into one or the other branch of the bifurcated
grooves.
The automatic directors K are shifted by the bobbin carriers o themselves
during their passage from one fixed guide plate Q to the other and then resume
their original positions under the action of a spring. These automatic directors k²
prevent the bobbin carriers from returning along the exit grooves and consequently
ensure the continuity of their progress or course.
This arrangement allows the bobbin carriers to be advanced in the longitudinal
direction of the guide plates by suitably adjusting by the pattern mechanism the
directors and by imparting only a simple to-and-fro motion to the actuators of the
bobbin carriers in a transverse direction as hereinafter explained.
The interlacement or crossing of the threads in a lace or braid machine necessitates
however as is well known the advancing of two series of bobbin carriers in
opposite directions and the alternate passage of each bobbin carrier of the one
series above and below or on opposite sides of a bobbin carrier of the other series.
The path or course of the bobbin carriers thus forms two uniform undulating
lines which intersect at the changing points of the curves.
Figure 20 (sheet 6) shows the undulating course that the bobbin carriers follows
in the present case it being remarked that the changing points of the curves are
prolonged in straight lines.
The bobbin carrier driving or actuating mechanism hereinafter described in
combination with the slotted or grooved guide plates further admits of the starting
and stopping at will of the bobbin carriers and consequently their advance in one
or the other direction as may be required in the production of the lace.
In my improved lace machine the bobbin carriers can be arrested on either of
the two fixed guide plates or on the intermediate moveable guide plate or bed R
(or R2) and as this last is so arranged as to allow it to be displaced at will longitu-
dinally in the manner hereinafter explained, it will be understood that the threads
can be interlaced at will to produce such classes of lace work as have only been
made hitherto by band as for example real Torchon lace real Valenciennes lace and
the like. The diagram figure 22 (sheet 6) illustrates the interlacing of the threads
in the simple style of lace (shown in the diagram figure 21) such as can be executed
by the present lace machine. As the mechanism hereinafter described and
illustrated at figures 7 to 11 for guiding and actuating the bobbin carriers is more
simple the present diagram is based thereon.
The diagram figure 22 represents the successive displacements of the bobbin
carriers for the production of the class of work indicated by diagram figure 21.
The twelve threads of this diagram or the bobbin carriers to which they appertain
are each marked with a number so as to enable their course to be more easily

page_text: recognized in figure 22 as well as their corresponding positions in figure 21. For
the same object the positions of the threads in figure 21 corresponding to each
position of the bobbin carriers in figure 22 are indicated by the corresponding
numbers of position. In the example figure 22 the guide grooves of the
plates QRQ are represented by transverse vertical lines connected together by
arcs, and the arrows drawn thereon indicate the direction of the course of the
bobbin carriers. The plate R³ must be considered as situate between the two
longitudinal horizontal lines and the direction of its movement is indicated by the
horizontal arrows drawn thereon. Thus for example the places of the bobbin
carriers 1, 2, 5, 6, 7, 8, 9, 10 and 11 correspond in the "position" N° 1 to the
internal position of the said bobbin carriers in the fixed plates Q and those of
the bobbin carriers 3 and 4 to the external position on these plates whilst on the
moveable plate R2 is found the bobbin carrier 12 the initial and terminal position
of which is indicated by the N° 12 placed on the corresponding guide grooves in
front of and in rear of the horizontal arrow. The mode of production of the
example of interlacing (Figure 21) will be readily understood on examining the
diagram Figure 22 where in the "Position" N° 24 the series is completed and where
the plate R which during its working was advanced towards the left to the extent
of two guide grooves in excess returns empty to its original "Position" N° 1 to
recommence the series.
The mechanism for producing the transverse traverse of the bobbin carriers o
(figures 7 and 10) is actuated by the before mentioned short spindles B connected
together by universal joints a figures 4 and 5) and which for this purpose carry
cams communicating a to-and-fro movement to the slide d by means of levers 6¹
and c¹ both mounted on the rocking shaft c.
It is this slided which serves to impart motion to the various bobbin carrier
actuating mechanisms and as it is required to actuate a number of these at one
time it is furnished with a connecting spindle or spindles d' disposed in a curved
line towards the interior or in the form of an arc (figures 4 to 6) to which spindles
are jointed the rods or connectors d² of the different mechanisms each rod d²
actuating a like mechanism the number of which corresponds to the number of
guide grooves of the lace machine.
The modification figure 7 being the most simple I will describe it first.
The rod d² actuates in this case the slotted links e' in which may be adjusted in
two directions the slide block of the rod e¹. The link e' is fixed to the lever e*
the pivot of which turns in a bearing fitted to the framing P¹. The arrangement
of the slotted link e' is such as to allow the movement of the slide block without
impediment as far as the geometrical axis of vibration of the link. This link is
curved to the arc of a circle in such a manner that the slide block can further be
brought into two other positions beyond that of the said axis of vibration of
the link.
The connecting rod e¹ actuates in its turn the lever f which is guided between
two plates f by means of which a horizontal sliding bar g₁ which gives the
transverse traverse motion to the bobbin carriers can be alternately moved in one
direction or the other through the intervention of the connecting rod f¹. This
sliding bar g' is provided with a fork or notch engaging with a pin fixed to the
lower end of the bobbin carrier (figure 7) which pin (hereinafter called the "foot
of the bobbin carrier") is not rounded as in the bobbin carriers of ordinary braid
machines but is of a flattened rectangular section having its larger dimension
placed perpendicularly or crosswise to the guide groove (figures 7 to 10).
Below each slot or groove of the moveable bed R2 or guide plate formed by the
plates m there is fitted one of these horizontal sliding bars g' (figures 8 and 9)
the connecting fork of which is as wide as the distance between two arms k¹
carrying the core pieces with the automatic fingers in the guide plate will admit
this width of the fork allows the latter to embrace the foot of the bobbin carrier
even when in the position shown in figure 10 or on one of the fixed guide plates.
and it must be understood that thus each fork will always command in each of

page_text: the two fixed slotted guide plates Q two grooves corresponding with the grooves
in the moveable guide plate and that therefore each of the guide grooves of the
two fixed guide plates has at its disposal two sliding bars g' with their forks
for moving the bobbin carriers. It results from the example of interlacing herein-
before described with reference to figures 21 and 22 that the movements of the
bobbin carriers in two adjoining grooves or slots of the moveable guide plate are in
opposite directions as required for the interlacing of the threads hence their
actuating horizontal sliding bars g' should only move the bobbin carriers in the
direction required by their course but as the movements of the bobbin carriers in
the transverse direction should be effected simultaneously in order to economise
time the movement of the two adjoining sliding bars g¹ should also be in opposite
directions.
This result is obtained by connecting the before mentioned connecting rod d² of
one of the slotted vibrating links to the said link at a point situate below the
centre of vibration and connecting the rod of the neighbouring link at a point
situate above its centre of vibration. Figure 7 shows the first arrangement and
figure 6 the last.
It also results from what has been above stated that each horizontal sliding bar g¹
should cease to act during its backward movement the fork of this bar being
disengaged or uncoupled from the foot of the bobbin carrier after having moved it
into the desired position which disengagement is effected by lowering the said
horizontal sliding bar.
To this end each of the sliding bars is guided between antifriction rollers mounted
in upright suspended bars h h which are raised and lowered as required by lever
arms h¹ h¹ and he h² and the coupling rod h*.
One of the levers h2 of the upright suspended bars h is connected in any well
known manner with a pattern governing or controlling mechanism which effects
as required the lowering of the upright suspended bars and consequently the
disengagement of the fork of the horizontal sliding bar g¹ whilst a spring effects
the raising of the same and consequently the re-engagement of its fork with the
foot of the bobbin carrier and vice versa.
Any of the well known pattern controlling or governing mechanisms now used
in lace machines may obviously be applied to the above purpose.
During the period of its return or back traverse the sliding bar remains lowered
and only engages afresh with the foot of the bobbin carrier during the change of
movement of its actuating lever f the curve of the cam 6 which works the said
lever being of such a form as to cause the lever f to pause or dwell for a short
time at each change in the direction of motion. It follows from the example of
interlacing shown at figure 22 that the bobbin carriers o should be capable of being
placed in position either upon one or the other of the two fixed guide plates Qor
upon the moveable guide plate R or R2. Besides these three positions the before
described arrangement (figure 7) allows of another position upon each of the fixed
guide plates Q with a view to admit of the placing of bobbin carriers in reserve
when necessary.
These five positions of the horizontal sliding bar necessitate three
positions of the slide block in the slotted vibrating link e which are effected by
raising and lowering the vertical guide bar e which embraces the sliding connecting
rode of the slide block by a pair of antifriction rollers as shown in figure 7.
For this purpose the said vertical guide bar e³ is jointed at its lower end to a
lever arm e which is maintained in its extreme elevated position by a spring and
thereby ensures also the extreme elevated position of the slide block in the slotted 5
link. This lever e is provided with two adjustable regulating slotted links e each
of which is connected as indicated by the dotted arrows to a suitable pattern
controlling or governing mechanism. The extreme upper position of the said
lever e is assured by the engagement of these links with studs or pins fixed in the
framing P¹ and a regulating screw by means of which the downward movement of 5
the lever is limited... By drawing, the outer regulating link e' the slide block is
brought into its middle position and on drawing out the inner regulating link then

page_text: slide block will be brought into a position where its central part will coincide with
the axis of vibration of the slotted link e. This last position of the slide block
corresponds to the position of the bobbin carriers o on the moveable slotted guide
plate R whilst the iniddle position of the slide block corresponds to what I have
hereinafter called the inner or "internal position" of the bobbin carriers on the
two fixed slotted guide plates Q and the upper position of the slide block
corresponds to what I have hereinafter called the outer or "external position" of
the bobbin carriers on the said fixed guide plates Q. The commencement of each
movement into a new position takes place during the movement of the slotted
link e*.
During their traverse the bobbin carriers are guided in the ordinary manner by
means of moveable directors or fingers which are connected to a pattern
controlling or governing apparatus. The detailed construction of these fingers is
shown in figures 10 and 11.
On the axis of each finger i is mounted a small lever i which is connected by
any suitable connector (guided by guide rollers ³) with a pattern controlling or
governing mechanism or apparatus.
The arrangement shown in figures 4 to 6 for determining the traverse of the
bobbin carriers o transversely to the fixed and moveable slotted guide plates Q R Q
differ from those described with reference to figures 7 to 11 in that the slide block
to which the rod e¹ is connected requires only two positions in the vibrating slotted
link e (Figure 6) in order to bring the bobbin carriers o into all their required
positions but in this case it is necessary that the before mentioned horizontal
sliding barg or g¹ be provided with two engaging forks and that the moveable
slotted guide plates of the bed R should be wide enough to enable the bobbin
carriers to take up two positions on the said moveable guide plate.
Moreover all the positions of the bobbin carriers o on the three slotted guide
plates QQR should be situated at exactly the same distance from each other,
which distance must correspond with the distance between the two engaging forks
on the orizontal slide bar g.
These arrangements allow (according as one or the other of the two engaging
forks is used in combination with the placing in suitable position of the respective
slide block within its vibrating slotted link) of giving to the bobbin carriers o the
position which I have called the "internal position" on each of the fixed slotted
guide plates Q as well as the second or "external position on the same guide
plates with the object of holding certain bobbin carriers in reserve precisely as in
the arrangement hereinbefore first described, But in the present case the placing
of the bobbin carriers in the "external position" alternates in the guide grooves
in such a manner that the fixed guide plate of the one side allows only of this
displacement in the even numbers of its grooves or slots whilst the fixed guide
plate of the other side allows such displacement only in the odd numbers of its
grooves or slots.
The moveable plate R² receives two positions and the rest will be readily
understood on referring to the diagram Figure 19 (sheet 6) which shows at the
lower part the various possible positions of the before mentioned horizontal sliding
bars gorg in relation to the slotted guide plates Q R Q which are indicated in
the upper part of the said diagram where are also shown the combinations or
permutations of displacement of the bobbin carriers corresponding to these
positions. Finally the diagram figure 22 shows further that the passage of a weft
of thread is effected by means of the moveable plate R2 which can be displaced in
a longitudinal direction as already described.
The longitudinal shogging movements of the moveable bed or guide plate R³
(or R figures 4 to 13) take place during certain periods of rest in the transverse
movements of the bobbin carriers for which object the actuating cam b is of such
a form that at each revolution the horizontal sliding bars gl make in addition to
two direct movements (for the displacement of the bobbin carriers) two inverse
movements and as they will be found during these latter movements in their

page_text: lowered positions two periods of repose will result at each rotation of the cams
which may be utilized for effecting the displacement of the moveable bed or guide
plate R (or R²). It is evident that the lowering of the horizontal sliding bars g¹
should be sufficient to allow of free play to the said moveable guide plate.
The arrangement of the moveable bed R is shown in figures 4 to 13 and as the
bed R2 differs only from R in the dimensions of its guide plates m' it follows that
what has been said with reference to the bed R applies equally to the bed R² and
vice versa.
The arrangement of moveable guide R or R$ consists of two sets or series of
slides the slides in each set being jointed together end to end by means of pins or
bolts m (figures 9 and 12). The opposite slides of each set are connected together
at the bottom by transverse bars so as to form a grating which allows a free passage
between the said transverse bars for the engaging forks of the before mentioned
horizontal sliding bars g' when in operation.
Each of these slides rests by four rollers m' (figures, 7, 9 and 12) in suitable
segmental shaped guides R¹ which are secured to the radial wings E previously
mentioned the guides being prolonged on both sides or ends sufficient to allow of
the desired displacement of the moveable bed or guide plate R. This latter passes
in its turn beyond the fixed guide plates Q on both sides for the same reason and a
certain number of the slides which are at the end of the moveable bed R are
furnished on both their lateral faces with driving pins or cogs m³ placed at
distances corresponding to the distances between the guide grooves (figures 7, 8, 12
and 13).
The actuating of the moveable bed R is effected by two special and similar
arrangements of mechanism one of which is disposed on each side of the machine
so that the movement of the bed towards the left shall be effected by the left hand
mechanism and towards the right by the right hand mechanism.
Each time that one of these actuating mechanisms is required to operate it is
coupled with the moveable bed R by means of a suitable pattern governing or
controlling apparatus or mechanism and can then effect the displacement of the
bed to the required extent which is also governed by the controlling mechanism.
The starting of this mechanism into action is effected through a vertical shaft K
driven from the main horizontal driving or first motion shaft A of the machine as
shown in figures 12 and 13.
The said vertical shaft K actuates through suitable bevel gear a short horizontal
shaft S which carries a cam S¹ making a number of turns equal to those of the
before mentioned cam b which actuates the horizontal slide for traversing the
bobbin carriers. This cam S' imparts a continuous oscillating or vibrating
movement to a slotted lever arm T mounted on a stationary axis T' by means of
the special coupling T¹ (figures 12 to 16) whilst the said vibrating slotted lever
arm T actuates through the connecting rod p a short lever arm U₁ fixed on a
horizontal rocking shaft U carrying also radial oscillating lever arms U³ which can
be suitably connected at their outer or free ends with the before mentioned
'moveable bed or guide plate R.
This connection of the radial lever arms U' with the said moveable bed R may be
effected by engaging the forked outer ends of the adjustable sliding forked pieces t
on such arms with the before mentioned driving pins or bolts m³ in the said bed
(see figure 12). For this purpose the said sliding forked pieces t can be moved
along the radial lever arms U2 as shown in figures 17 and 18 and brought into
action as required by the bell crank levers t¹ and a suitable pattern controlling or
governing mechanism (figures 12, 13, 17, and 18). These bell cranks t¹ work in
brackets fixed to the radial levers U2 and engage with sliding collars t2 on the
horizontal shaft U which collars again engage with the levers u coupled together
by a bar U (figures 12 and 13) so that the engagement and disengagement of the
two sliding forked pieces t shall take place through a movement of one of the
levers which is effected by the aid of suitable pattern controlling mechanism as
indicated by the arrow in figure 13.

page_text: Provision is made for regulating as required the amount of displacement of the
moveable bed R by varying the position of the end of the connecting rod p in the
vibrating slotted lever T which may be effected by a regulating sliding bar pl
guiding the said connecting rod along the slot by means of antifriction rollers. The
regulating sliding bar p' is connected to the lower end of a lever q mounted on an
axle r on which are carried freely other levers q¹ to q connected with a pattern
governing or controlling mechanism.
On pulling one of this range or series of levers say the shortest one q³ as shown
in figure 12 the stirrup r¹ fixed on the axler which carries the said levers is
caused to move that axle along with its vertical vibrating lever 9; Now the
levers q to q being of different lengths it is sufficient to actuate one or the other
of them in order to vary proportionately the movement of the vertical lever q and
consequently the position of the end of the connecting rod p in the slotted lever T.
In the arrangement shown in figure 12 there are eight different causes possible
for the levers q which correspond to 8 different movements of the bed R increasing
regularly by the distance which separates two guide grooves.
The lever Չ is disposed in such a manner as to be disengaged from the sliding
regulating bar p¹ so as to allow to this last the horizontal movement that it should
make during the working of the vibrating slotted lever T according to the position
of the slide block z¹ therein.
For this object the lever q slides on a feather on its axis and it is disengaged
during the operation of the slotted lever T by a cam or finger & which acts upon it
by means of the levers s¹ s2 §³
The fixing in proper position of the slide block z¹ in the slotted lever T has for
its object the allowing of the placing into exact position of the moveable bed R
and this fixing is obtained by providing the slide block z with a tooth capable of
engaging in a rack z the notches of which should correspond in position and number
to the required amount and number of movements of the moveable bed R. This
rack z is guided on guide pins fixed to the slotted lever T and hung to bell crank
levers y and y connected together by a coupling bar y' and can be engaged and
disengaged by means of tappets on the cam S which actuates the said bell crank
levers as shown in figures 14 to 16. The engagement is effected directly after the
adjustment of the connecting rod p by the vertical lever q that is to say towards
the end of the pause of the slotted lever T allowed by the cam S¹ in the position
shown in figures 12 and 14. The adjustment of the position of the slide block z¹
in the slotted lever T having been effected the said lever immediately commences
its descent and maintains the slide block z¹ in place till it again returns to its
position of repose. It is at the moment when the slotted lever completes its ascent
that the disengagement of the rack takes place at the same time as the
engagement of the lever q with the sliding regulating bar.
As each of the above described mechanisms only effects the movement of the
moveable bed R in one direction as before stated it follows that the adjustable
forks of the radial levers U should be disengaged during their return. This
disengagement takes place immediately after the completion of the movement of
the moveable bed R and at the same time the engagement of another or stop
mechanism is effected in order to maintain the moveable bed R in its new position
and ensure the exactness thereof.
The bringing into action of this last arrangement is effected by the shaft B which
carries a cam v (figures 12 and 13) acting upon a bell crank which in turn
produces the oscillation of the shaft w by means of the rod v² and lever w
On this shaft ware mounted two levers w² which move the arresting tooth w³
in its guides w' and this tooth by entering during its descent between two of the
engaging pins or bolts m³ of the moveable bed R determines and ensures its being
placed in exact position.
When the moveable bed R is to be fixed for a greater or less period of time then
the cam vis moved together with the bell crank lever v3 which is connected with a
suitable pattern controlling or governing mechanism as shown by the arrow in

page_text: figure 12. Thus the stop tooth 203 can remain in its place as long as the work
requires.
In order to effect the pushing of the crossings of the interlaced threads towards
the braiding point I combine with my said improved machine the arrangement of
beaters described in the: specification to my patent No 2441 A.D. 1883 the position
of which is indicated by the letter M in figures 1 to 3 of the drawings hereunto
annexed. This arrangement is actuated by the before mentioned vertical shaft K
through the two horizontal shafts L L¹ driven therefrom by bevel gear.
Further the fixing of the crossings and the taking up of the work as it is
produced is effected by the needle mechanism and take up rollers described in the
specification to my patent N° 3357 A.D. 1882 which mechanism and take-up rollers
I also combine with my said improved machine.
The position of this needle mechanism and take-up rollers is indicated by the
letter figures 1 to 3. It is driven from the horizontal shaft L and the short
vertical shaft N all geared together.
Finally I combine with my said improved lace machine the pattern governing or
controlling mechanism described in the specification to my patent N° 2568
A.D. 1881 for bringing into action as required the various parts or groups of
mechanism of my present machine according to the requirements of the pattern or
nature of the work to be produced therein. Its position and mode of driving or
actuating the same is shown at I in figure 3. It is driven direct from the principal
or first motion shaft A of the machine. The connection of the various parts of the
machine with the said pattern governing or controlling mechanism is effected by
the aid of cords chains or wires combined where found requisite with guide rollers
levers or other suitable or well known guiding appliances.
If desired my improved lace machine may be simplified by replacing the
moveable guide plate R or R2 by a fixed guide plate and by uniting the three fixed
plates in one, said plates being provided with guiding grooves or slots either
intercrossing each other or bifurcated at their extremities and with directing
fingers such as I have already described the whole being used in combination with
the before mentioned mechanism for effecting the traverse of the bobbin carriers.
Having now described and particularly ascertained the nature of my said
