This invention relates more particularly to the beaters or mechanism employed in
lace and braid making machines for pushing the crossings or interlacements of the
threads towards the braiding point and to the mode of driving or actuating such
mechanism and governing its action by a jacquard machine or equivalent pattern
mechanism.
According to my invention I employ two swinging or oscillating frames vibrating
on centres near their upper ends and a series of beaters or fingers hinged to the
lower part of one of the said frames each heater being capable of being coupled at
any moment required with the second frame by means of a hooked coupler or
connecting rod jointed to the hinged end of the beater or finger which is bent at
that part to form a bell crank such hooked coupler being governed by a jacquard
machine or other pattern mechanism. An oscillating movement is imparted to
both these frames by crank pins working in slotted cam pieces attached to the said
frames thereby causing the beaters or fingers first to advance and pass their free
ends between the threads and beneath the crossings or interlacements of the same
and then by an upward angular movement on their centres to push up the crossings
towards the braiding point in order to tighten or secure the crossings already made.
The said hooked couplers are caused to engage with or are released from a plate

a series of upright sliding rods or wires converging towards the braiding point
which are maintained elevated by springs and are drawn down by the pattern
mechanism with which each rod or wire is connected by a bell crank and suitable
connectors. So long as any one or more of the rods or wires remain elevated the
corresponding hooked couplers passing through them will be disengaged from the
actuating plate in the second oscillating frame and will be engaged again when
the corresponding rod or wire is drawn downwards by the pattern mechanism.
The forward and backward motion of the beaters towards and from the threads
is derived solely from the oscillation of the frame to which they are hinged but
their upward and downward or angular motion on their hinged centres is imparted
by the action or pull of the hooked couplers when engaged with the second
oscillating frame. According to another arrangement the aforesaid movements of
the beaters may be obtained from slides or carriages caused to travel or move
horizontally or at a slight angle by the action of cams eccentrics or crank slots as
will be readily understood in lieu of the said beaters deriving their movements
from oscillating or swinging frames, the other arrangements remaining unaltered.
Having indicated generally the nature and mode of operation of my improve-
ments I shall proceed to set forth the manner in which I propose to carry out the
same. To the two cross bars which connect the standards of the lace machine,
that is to say to the upper one which carries the "take-up" mechanism referred
to in the specification to my Patent No 3357 A.D. 1882 and to a lower one serving
to strengthen the machine, I fix two brackets between which I dispose the beater
mechanism and accessory parts. The two oscillating frames before referred to when
employed are hung near their upper ends from adjustable centres in suitable side
uprights attached to the brackets. The motion is imparted to the frames direct
from the loom through suitable gearing rotating by preference at the same rate as
the shaft for actuating the jacquard. For this purpose the main driving shaft
actuates through spur or bevel gearing a second shaft which in turn drives a third
shaft working in bearings in the brackets above mentioned. To each end of this
shaft there is fixed a crank the pin of each of which, provided with an antifriction
roller works in a suitable slotted cam piece attached to the side of one of the
oscillating frames and imparts the requisite oscillating motion thereto. The said
crank shaft transmits its movement through a carrier wheel mounted on a cross
bar between the brackets to a corresponding crank shaft, which in like manner
actuates the second oscillating frame similarly mounted to the first but placed
slightly in the rear thereof. The front frame carries at its lower part the beaters
or fingers above referred to, each beater being hinged to the frame and having con-
nected to it a hooked coupler capable of sliding freely in a guide slot in a plate in
the second or rear frame but also capable of being hooked onto or engaged with
the said plate as required the oscillations of which plate determine the advance or
withdrawal of the said coupler and consequently the lifting or lowering of the
corresponding beater or finger. As it is desirable to be enabled to bring the
beaters towards the braiding point according to requirement the movement thereof
is governed by the following arrangement. The hooked couplers pass through the
eyes of the convergingly disposed rods wires or needles and these are each con-
nected with a jacquard by means of bell cranks. The said vertical needles are
guided by holes or slots in a suitable guide frame conveniently situate between the
brackets before mentioned. These needles are constantly pushed upward by
springs attached above the guide frame and remain in their elevated position until
drawn downwards by the jacquard or pattern mechanism. On drawing down any
of the needles the corresponding hooked coupler is also lowered which in its
elevated position was free to slide through its guide slot in the guide plate during
the oscillation of the same but when lowered it hooks itself onto the edge of the
said guide plate and imparts to the beater or finger the required upward and
downward movement.
The movement of the beaters or fingers is also modified or controlled by the

page_text: oscillations of the frame to which they are jointed and the curved slots in the
slotted cam pieces are so constructed as to produce at each revolution of the cranks
the following positions:
First Position. The first or front frame is at the end of its movement to the
right near to the threads where it pauses or dwells for a certain time; the second
frame on the contrary is slightly in arrear as regards the first so that the hooked
couplers are still retained and compel the beaters to maintain their lowest position
outside the threads.
Second Position. The front frame remains in its terminal position to the right
whilst the rear frame completes its movement towards the threads and also reaches
its terminal position to the right where it pauses or dwells for a certain time. The
beaters or fingers are thus caused to rise and attain their highest position between
the threads at the braiding point.
.
Third Position. The front frame commences to retire as well as the rear frame
and by their simultaneous and uniform movements the beaters are withdrawn
nearly horizontally away from the threads.
Fourth Position. The front frame has reached its terminal position to the left
and begins to return to the right. The rear frame has also reached its terminal
position to the left where it rests for a moment.
Fifth Position. The front frame is advanced in relation to the rear one a certain
distance referred to in the first position. The beaters or fingers are brought to
their lowest position by reason of the retention of the hooked couplers. The rear
frame has completed its period of rest and commences to advance.
In order to maintain the hooked couplers steady after having been elevated so
that the ends of the beaters or fingers shall maintain their lowest position without
interfering with the braiding or intercrossing notwithstanding the oscillations of
the front frame, the said couplers are provided with a projection by which they
bear against a plate attached to the front frame so soon as they are elevated by
the needles.

FRIEDRICH EDUARD AUGUST BÜSCHE of Schwelm Westphalia in the Empire
of Germany Manufacturer. IMPROVEMENTS IN MACHINERY OR APPARATUS FOR
THE MANUFACTURE OF LACE AND OTHER LIKE ORNAMENTAL OR PLAIN FABRICS
APPLICABLE ALSO TO THE MANUFACTURE OF ORNAMENTAL OR PLAIN BRAIDS
رو
My said Invention relates to the beaters or mechanism employed in lace and
braid making machines for pushing the crossings or interlacements of the threads
towards the braiding point and to the mode of driving or actuating such mechanism
and governing its action by a Jacquard machine or equivalent pattern mechanism.
According to my invention I employ two swinging or oscillating frames vibrating
on centres near their upper ends and a series of beaters or fingers hinged to the
lower part of one of the said frames each beater being capable of being coupled at
any moment required with the second frame by means of a booked coupler or
connecting rod jointed to the hinged end of the beater or finger which is bent at
that part to form a bell crank such hooked coupler being governed by a Jacquard
machine or other pattern mechanism. An oscillating movement is imparted to both
these frames by crank pins working in slotted cam pieces attached to the said
frames or by any other suitable cam arrangement causing the beaters or fingers
first to advance and pass their free ends between the threads and beneath the
crossings or interlacements of the same and then by an upward augular movement
on their centres to push up the crossings towards the braiding point in order to
tighten or secure the crossings already made. The said hooked couplers are caused
to engage with or are released from a plate or bar in the second oscillating frame
by passing thein separately through eyes in a series of upright sliding rods or wires
converging towards the braiding point which are maintained elevated by springs
and are drawn down by the pattern mechanism with which each rod or wire is
connected by a bell crank and suitable connectors. So long as any one or more of
the rods or wires remain elevated the corresponding hooked couplers passing through
them will be disengaged from the actuating plate in the second oscillating frame
and will be engaged again when the corresponding rod or wire is drawn downwards
by the pattern mechanism. The forward and backward motion of the beaters.
towards and from the threads is derived solely from the oscillation of the frame to
which they are hinged but their upward and downward or angular motion on their
hinged centres is imparted by the action or pull of the hooked couplers when
engaged with the second oscillating frame.
Or the aforesaid movements of the beaters may be obtained from slides or
carriages caused to travel or move horizontally or at a slight angle by the action of
cams eccentrics or cranks and differential slots as will be readily understood in lieu
of the said beaters deriving their movements from oscillating or swinging frames
the other arrangements remaining unaltered.
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 sheet of drawings hereunto annexed the same
letters of reference indicating corresponding parts in all the corresponding figures.
Figure 1 is a vertical section taken along the line 3-4 in figure 3 of my
improved machine. Figure 2 is a vertical section of the same taken along the
line 5-6 in figure 3. Figure 3 is a corresponding plan of the machine and
figures 4 and 5 are details of a portion of the mechanism employed for pushing the
crossings or interlacements of the threads towards the braiding point.
To the cross bar A (figures 1 and 2) which corresponds to one of the two cross
bars marked V V in the drawings annexed to the specification to my patent
No 3357 A.D. 1882 which connect the columns or standards of my lace machine
and which carry the "take-up" mechanism as described in the said specification

page_text: and also to a lower cross bar B (figures 1 and 2 of the drawings hereunto annexed)
which serves to strengthen the machine I fix two brackets M between which I
dispose my improved heater mechanism and accessory parts hereinafter more fully
described consisting of two swinging or oscillating frames QQ vibrating on centres
near their upper ends in the upright supports M' M' fixed to the said brackets M.
Motion is imparted directly to these frames from the machine by bevel gearing
arranged by preference to rotate at the same rate as the driving shaft of the
Jacquard machine. For this purpose the shaft J which is driven from the main
vertical shaft of the lace machine actuates the shaft i¹ which transmits rotary
motion to the shaft a suitably mounted in bearings near the brackets M. To each
end of the shaft s is fixed a crank the pin of which carries an antifriction roller
and travels in its revolution along the curved slotted cam pieces t (Figure 5.) fixed
laterally to the frame Q and determining the particular oscillating motion of the
same. Figure 5 shows the curved slot t and crank a in detail on a larger scale.
The shaft a transmits its motion to the shaft s¹ (figure 1) through an intermediate
spur wheel carried by the cross bar N. This shaft s is also provided with cranks
the pins of which carrying rollers working in the curved slots of the cam pieces t¹
impart the required oscillating movement to the frame Q₁ as shown more clearly in
the enlarged detail figure 4. The front frame Q carries the fingers n (figures 1
and 2) the function of which is to bring the crossings of the threads towards the
braiding point. For this purpose the fingers n are each hinged to the lower part
of the frame Q and are each connected by a short lever arm to a hooked coupler u
which is capable of sliding freely through a guide slot in the catch plate z fixed to
the rear frame Q¹ and of being hooked onto or engaged with the edge of the said
plate as required the oscillations of this frame Q thus determining the forward and
backward motion of the said coupler as well as the rising and falling of the end of
the corresponding finger n. As it is desirable to be enabled to move the fingers n
towards the braiding or crossing point according to requirement this movement of
the fingers is determined by the following mechanism.
The hooked couplers u pass through the eyes of the convergingly disposed rods
wires or needles and these latter communicate with a Jacquard or other pattern
mechanism through the intervention of bell crank levers as shown in Figure 1.
The needles are themselves guided by slots. or holes in the segmental or curved
guide frames w conveniently placed for this purpose between the brackets M.
These needles are each constantly pressed upwards by a spring fixed to the upper
side or the frame w (see figure 1) and remain in this elevated position until lowered
by the actuating mechanism. On causing any one of the needles v to descend its
corresponding hooked coupler u is also lowered which whilst in its elevated position
is free to slide through its guiding slot during the oscillation of the frame Q¹ but
which when lowered becomes hooked onto or engaged with the edge of the plate z
and is moved along with it thereby imparting to the corresponding finger its
upward or downward motion. This movement of the fingers n is still further
modified by the oscillations of the frame Q to which they are hinged and the
curves of the slots in the cam pieces t t¹ are so designed as to produce the following
positions at each revolution of the cranks.
First Position. The frame Q will be found at the extreme limit of its course or
movement to the right or towards the interlacing threads in which position it pauses
or dwells for a certain time; the frame Q on the contrary has not yet completed
its course being in arrear to a certain extent in relation to the frame Q so that the
engaged hooked couplers u being retained compel the fingers n to maintain their
lowest position away from the braiding point of the threads.
Second Position. The frame Q remains in its extreme position to the right
whilst the frame Q1 completes its course or movement towards the threads and
attains its terminal position to the right where it pauses and dwells for a moment.
The fingers are thus caused to move upwards on their binges whilst between the
threads and thus reach their highest position at the point of interlacement or
crossing of said threads.

page_text: Third Position. The frame Q commences to retire as well as the frame Q¹ and
by their simultaneous and uniform backward motion withdraw the fingers n in a
nearly horizontal direction from the crossings of the threads. Figures 4 and 5
illustrate the corresponding positions of the two cranks x x in their respective
slots t¹, the cranks revolving in the direction of the arrows.
Fourth Position. The frame Q has reached the end of its course to the left and
commences its return movement towards the right. The frame Q¹ has also reached
the end of its course towards the left where it pauses or dwells for a moment.
Fifth Position. The frame Q is advanced in, relation to the frame Q¹ a certain
distance corresponding to the distance which the frame Q¹ was in arrear thereof in
the first position already described. The fingers n are turned down to their lowest
position by reason of the retention of the hooked couplers u. The frame Q¹ having
completed its period of rest commences to advance towards the right and the
several movements are repeated as before. In order to maintain the hooked
couplers firm and steady after having been elevated by the needles vso that their
corresponding fingers n shall be kept in their lowest position without interfering
with the braiding or intercrossing notwithstanding the oscillations of the frame
the said hooked couplers are provided with a projection which encounters a stop
plate fixed to the frame Q so soon as the couplers are elevated by the needles v.
The engagement of the hooks with the plate z can be most conveniently effected in
the First Position or a little before whilst their disengagement should be effected
in the Fifth Position.
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
and therefore claim as the invention secured to me by the hereinbefore in part
recited Letters Patent is :-
First. The application and use to and in lace and braid making machines of the
peculiar mechanism for pushing the crossings of the threads to the braiding point
consisting of two swinging frames or traversing carriages actuated independently
by cam surfaces to one of which frames are hinged a series of fingers connected by
hooked couplers with the second frame and brought into action as required by a
Jacquard machine or other pattern mechanism substantially as hereinbefore
described. -
Second. The combination of two swinging frames or traversing carriages moving
independently of each other so as to impart a forward and backward and an
upward and downward motion to the fingers which push the crossings of the
threads to the braiding point substantially as hereinbefore described.
Third. The combination of a slotted catch plate mounted on one of the said
swinging frames or traversing carriages with hooked couplers traversing a series of
vertically moving needles or wires governed by pattern mechanism and springs
for bringing into or throwing out of action any one or more of the fingers as
required substantially as herein before described.
Fourth. The general combination and arrangement of fingers and their actuating
mechanism as and for the purpose hereinbefore described and illustrated by my
drawings.
In witness whereof I the said Friedrich Eduard August Büsche have hereunto
set my hand and seal this eleventh day of November in the year of our Lord
one thousand eight hundred and eighty three.
