PROVISIONAL SPECIFICATION left by the said Friedrich Eduard August
Büsche at the Office of the Commissioners of Patents on the 13th June 18S1.
FRIEDRICH EDUARD AUGUST BÜSCHE, of Schwelm, Westphalia, in the Empire
of Germany, Manufacturer. "IMPROVEMENTS IN APPARATUS FOR REGULATING
OR GOVERNING THE PATTERNS OF WORK TO BE PRODUCED IN BRAIDING AND
OTHER LIKE MACHINES."
This Invention relates to a modification of what is known as a jacquard
machine, such modification being principally adapted for use in connection with
braiding machines and other machines of like character, but more particularly in
inachines of the construction described in the Specification to my Patent bearing date
the 12th of July 1880, No. 2864, for the purpose of actuating the various stop
actions and directors therein referred to. Heretofore it has not been found
practicable to employ the ordinary arrangement of jacquard apparatus in con-
nection with a braiding machine, as the course of the bobbin carriers and their
delivery from one notched disc wheel to another necessitates a peculiar action of
the pattern regulating apparatus, which action differs essentially from that of the
ordinary jacquard machine heretofore employed in connection with looms for fancy
weaving.
My improved apparatus consists generally of a standard or frame carrying a
horizontal rotary shaft driven from the braiding machine by suitable driving gear
and carrying a cam for imparting the required peculiar lifting motion to the slide
which carries the lifter bars. This cam is so shaped as to allow of the slide to
descend suddenly and be lifted again immediately afterwards, and to remain at
rest in its elevated position during the relative longer period required for the com-
pletion of the revolution of the cam, these motions corresponding to the quick and
D

page_text: sudden motion of the directing fingers or "directors" of the braiding machine,
and their pause or dwell during the time of the passage of the bobbin carriers, as
well as to the required motion of the stop actions in the said braiding machine.
The directing fingers as well as the stop actions are connected with the booked
wires of my improved pattern apparatus by wires or other suitable connectors
combined with the requisite bell crank or other levers or guide rollers. The said
hooked wires pass through loops or eyes in a series of horizontal wires or needles
acted upon by perforated pattern cards as in an ordinary jacquard, the hooked
wires being lifted by the lifter bars in the slide before referred to. The peculiar
movement of the lifting slide does not admit of the combining or connecting of
the movement of the card cylinder or prism with that of the said slide, therefore
the card cylinder receives its to and fro horizontal motion direct from an eccentric,
carried by preference on a separate horizontal shaft. In applying my improved
pattern apparatus to my before mentioned improved braiding machine I may
employ in small machines as many repeats of the said pattern apparatus as there
are main or principal notched disc wheels in the braiding machine, and in larger
machines one pattern apparatus may be made to operate upon two or more
principal notched disc wheels. All the repeats of the pattern apparatus disposed
on the same side of the braiding machine derive their motion by preference from
one shaft common to the series carrying the several lifting cams, and from a
second shaft also common to the series carrying the several eccentrics for actuating.
the card cylinder of each apparatus both shafts being driven from the braiding
machine. All the before mentioned cams and eccentrics are made adjustable round
their respective shafts for the facility of accurately timing their action.
This Invention also embraces a further improved modification or arrangement of
jacquard machine for the purposes hereinbefore set forth, whereby I am enabled to
allow the before mentioned hooked wires to remain elevated after having been
Jifted during any period of time required, although the slide with its lifter bars
continues its usual up and down movements produced by the action of the cam
before referred to, and as the stop actions and directing fingers are connected with
the said hooked wires these parts of the braiding machine will by this further
improvement be also enabled to remain stationary during any desired length of
time in the position into which they have been brought by the elevation of the
hooked wires, thereby considerably reducing the wear and tear chiefly of the stop
actions and ensuring a smoother and more regular action of the braiding machine.
This further improvement consists in the employment of one or more hooked stop
levers in combination with and passing down through loops or eyes in one or
more of the horizontal needles belonging to the hooked wires, the said hooked
stop levers being freely suspended at their upper ends from an axis common to the
series and having a hook formed at their lower ends. This hook is so shaped as
to engage with a pin connected directly with the vertical hooked wire or indirectly
therewith through the intervention of a lever arm. The act of lifting the vertical
hooked wires ensures the engagement of the pin with the corresponding suspended
stop lever when in its highest position, thereby maintaining the hooked wires in their
elevated position as long as required, but should an immediate descent of one or
more of the hooked wires be necessary, this can be effected with the requisite
promptitude, as the eccentric which actuates the card cylinder or prism is so
adjusted as to allow the latter to have completed its advance before the slide
carrying the lifter bars has commenced a fresh ascent, thereby allowing the said
hooked wire or wires to descend at the proper time.

by the said Friedrich Eduard August Büsche in the Great Seal Patent
Office on the 13th December 1881.
FRIEDRICH EDUARD AUGUST BUSCHE, of Schwelm, Westphalia, in the Empire
of Germany, Manufacturer. "IMPROVEMENTS IN APPARATUS FOR REGULATING
AND GOVERNING THE PATTERNS OF WORK TO BE PRODUCED IN BRAIDING AND
OTHER LIKE MACHINES."
My said Invention relates, firstly, to a modification of what is known as a
jacquard machine, such modification being principally adapted for use in connection
with braiding machines and other machines of like character, but more particularly
in machines of the construction described in the Specification to my Patent, bearing
dato the 12th of July 1880, No. 2804, for the purpose of actuating the various
stop actions and directors therein referred to. Heretofore it has not been found
practicable to employ the ordinary arrangement of jacquard apparatus in con-
junction with a braiding machine, as the course of the bobbin carriers and their
delivery from one notched disc wheel to another necessitates a peculiar action of
the pattern regulating apparatus, which action differs essentially from that of the
ordinary jacquard machine heretofore employed in connection with looms for fancy
weaving.
My improved apparatus, as comprised under the first part of my Invention,
consists generally of a standard or frame carrying a horizontal rotary shaft driven
from the braiding machine by suitable driving gear, and carrying a cam for
imparting the required peculiar lifting motion to tho slide which carries the lifter
bars. This cam is so shaped as to allow of the slide to descend suddenly and be
lifted again immediately afterwards, and to remain at rest in its elevated position
during the relative longer period required for the completion of the revolution of
the cam, these motions corresponding to the quick and sudden motion of the
directing fingers or "directors" of the braiding machine & their pause or dwell
during the time of the passage of the bobbin carriers as well as to the required
motion of the stop actions in the said braiding machine. The directing fingers as
well as the stop actions are connected with the hooked wires of my improved
pattern apparatus by wires or other suitable connectors combined with the requisite
bell crank or other levers or guide rollers. The said hooked wires pass through loops
or eyes in a series of horizontal wires or needles acted upon by perforated pattern
cards as in an ordinary jacquard, the hooked wires being lifted by the lifter bars
in the slide before referred to. The peculiar movement of the lifting slide docs
not admit of the combining or connecting of the movement of the card cylinder or
prism with that of the said slide, therefore the card cylinder receives its to and
fro horizontal motion direct from an eccentric carried by preference on a separate
horizontal shaft.
In applying my improved pattern apparatus to my before mentioned improved
braiding machine, I may employ in small machines as many repeats of the said
pattern apparatus as there are main or principal notched disc wheels in the
braiding machine, and in larger machines one pattern apparatus may be made to
operate upon two or more principal notched disc wheels. All the repeats of the
pattern apparatus disposed on the same side of the braiding machine derive their
motion by preference from one shaft common to the series carrying the several
lifting cams, and from a second shaft also common to the series carrying the
several eccentrics for actuating the card cylinder of each apparatus, both shafts
being driven from the braiding machine. All the before mentioned cams and
eccentrics are made adjustable round their respective shafts for the facility of
accurately timing their action.

page_text: The second part of my Invention also embraces a further improved modification
or arrangement of jacquard machine for the purposes hereinbefore set forth, whereby
I am enabled to allow the before mentioned hooked wires to remain elevated after
having been lifted during any period of time required, although the slide with its
lifter bars continues its usual up-and-down movements produced by the action of
the cam before referred to, and as the stop actions and directing fingers are con-
nected with the said hooked wires these parts of the braiding machine will by this
further improvement be also enabled to remain stationary during any desired
length of time in the position into which they have been brought by the elevation
of the hooked wires, thereby considerably reducing the wear and tear chiefly of the 1
stop actions, & ensuring a smoother and more regular action of the braiding.
machine. This further improvement consists in the employment of one or more
hooked stop levers in combination with and passing down through loops or eyes in
one or more of the horizontal needles belonging to the hooked wires, the said
hooked stop levers being freely suspended at their upper ends from an axis common
to the series, and having a hook formed at their lower ends. This hook is so
shaped ns to engage with a pin connected directly with the vertical hooked wire or
indirectly therewith through the intervention of a lever arm. The act of lifting
the vertical hooked wires ensures the engagement of the pin with the corresponding
suspended stop lever when in its highest position, thereby maintaining the hooked
wires in their elevated position as long as required; but should an immediate
descent of one or more of the hooked wires be necessary this can be effected with
the requisito promptitude, as the eccentric which actuates the card cylinder or
prism is so adjusted as to allow the latter to have completed its advance before the
slide carrying the lifter bars has commenced a fresh ascent, thereby allowing the
said hooked wire or wires to descend at the proper time.
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.
The first part of my Invention hereinbefore referred to is illustrated by Figures
1, 2, and 3 of my Drawings. Figuro 1 is a vertical section taken along the line 3-4
in Figure 3 of my said improved jacquard machine or pattern regulating apparatus ;
Figure 2 is a front elevation of the same; and Figure 3 is a general plan and
partial horizontal section thereof taken along the line 1-2 in Figure 1.
One of the most important features of this the first part of my Invention consists
in the employment of a cam u fixed on the rotary shaft W, driven by any suitable
driving gear from the braiding machine for the purpose of imparting to the slide 9
the peculiar lifting motion hereinbefore referred to, and causing it to slide up and
down vertically within the main frame or standards A of the jacquard machine.
Another important feature consists in the employment of an eccentric y or its
equivalent fast on the separate horizontal shafts, also driven from the braiding
machine, from which eccentric the card cylinder x, resting with its axis in the
horizontal sliding pieces ¹ (as shown in Figure 3) receives separately its to-and-fro
horizontal motion. When in motion the cam u rotates along with its axis W, and
bears on its periphery the slide g through the intervention of the anti-friction
roller. The slide g carries the lifter bar or bars f, which when lifted lifts with
it or them all the hooked wires & which have not been pushed back by the cards s
on the card cylinder x, as is well understood, the booked wires d being returned to
their former position by means of springs or weights suitably adapted to the parts
of the braiding machine with which they are connected. These hooked wires d
pass through loops or eyes in the horizontal wires or needles 7, as shown clearly in
Figure 1, acted upon by the cards 8 on the usual jacquard cylinder or prism x, the
needles being guided by the plates t¹, t², t³. The hooked wires d are by preference
combined as shown with the lever arms d', such arms being guided by the guiding
plate d, which at the same time limits their downward motion. The hooke

page_text: lovers g, one of which may be disposed on each side of the machine, serve to impart
the requisite impulse to the card cylinder x to cause it to make a quarter of a
revolution during its backward stroke, as in the ordinary jacquard. The bar q³
(see Figure 2) which is disposed so as to facilitate the rotating of the card cylinder
and to impart steadiness thereto in its final position rests upon four pins or studs in
the card cylinder as in ordinary jacquards, and is pressed against them by the action
of sliding pieces or pins passing through and guided by the plate or bar q¹, the said
sliding pieces or pins being constantly pressed downwards by springs, as shown
clearly in Figure 2. The horizontal slides a' (Figure 3), in which the axis of the
card cylinder rotates are caused to slide within corresponding guiding slots or
grooves in the said standards A by the action of the forked arms of the eccentric
ring disposed round the eccentric y. In certain cases, as, for example, where an
irregular motion of the card cylinder might be found desirable the eccentric y might
be replaced by a cam, such cam or cams being provided with a groove or grooves
for imparting the peculiar motion to the driving arm or arms of the card cylinder.
The second part of my Invention heroinbefore referred to is illustrated by
Figures 4, 4, and 5 of the Drawings. Figure 4 represents a vertical section of one
arrangement thereof. Figure 4ª is a similar view of a modified arrangement taken
along the line 5-6 in Figure 5; and Figure 5 is a general plan of the arrange-
ment shown in Figure 4. The most important feature of this part of my
Invention is the making provision for allowing the hooked wires d to remain
elevated during any desired period of time after having been lifted, although the
slide with its lifter bars continues its up and down motion under the action of the
cam, herein before referred to. In carrying out this second part of my Invention,
1 suspend freely from an axis situate between the standards A, hooked stop:
levers, which pass down through eyes or loops in the horizontal needles r,
whether such needles be the needles belonging to the hooked wires d as shown in
Figure 4, or whether they be separate or special needles r, as in Figure 4º.
These suspended stop levers 7 are formed with a hook at their lower free ends,
so shaped as that when the hooked wire and its lever arm dare lifted, the
said hook engages with a pin in the lever arm d¹ thus maintaining this lever d',
and with it the hooked wire d stationary in an elevated position, so long as the
horizontal needles are not forced back by the cards on the card cylinder in the
usual way. When the card has no perforation therein corresponding to the needle
r, the said needle will be pushed back and thereby disengage the corresponding
stop lever r, thus allowing the hooked wire d to descend to its former position
under the action of a spring or weight with which it is connected in the braiding
or other machine. All the other parts of the pattern apparatus may be the same
as already described under the first part of my Iuvention with reference to
Figures 1, 2, and 3, and are marked with corresponding letters of reference.
It will be obvious that a reverse arrangement of the stop lever I might be
readily effected without altering the principle of the apparatus. For this purpose
the stop lever might be pivotted freely at its lower end to the lever d', in lieu of
being suspended from above, and have its hook formed at the upper end of such
stop lever in lieu of at the lower end as before. This hook is to be placed in the
same direction as the hook of the hooked wire d, and bears against a bar fixed
between the standards A of the machine in place of the axis of suspension of the
stop levers, shown in Figures 4 and 4. It will thus be seen that when d and d¹
are lifted, the reversed stop lever r will be also lifted and its upper hooked end
will, by the action of the spring of the needle r engage with the before mentioned
bar which is fixed between the standards and is common to the series of stop levers.
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 Lotters Patent is,-
First. The peculiar construction and arrangement of Jacquard or pattern

page_text: regulating apparatus and mode of applying the same for regulating or governing
the patterns of work to be produced in braiding and other like machines,
substantially as hereiubefore described and illustrated by Figures 1, 2, and 3 of
the Drawings hereunto annexed.
Secondly. The imparting a differential motion by means of a cam on a rotary
shaft to the slide which carries the lifter bars of a jacquard or pattern regulating
apparatus to be used in connection with a braiding or other like machine, whereby
the said slide shall be caused to descend suddenly, to be lifted again immediately
after, and to make a pause or dwell in its elevated position during the relatively
longer period required for the completion of the revolution of the actuating cam,
substantially as and for the purpose herein before described.
Thirdly. In a jacquard or pattern regulating apparatus wherein the lifting slide
partakes of the peculiar differential movement above set forth, I claim imparting
the to-and-fro horizontal motion to the card cylinder by an eccentric or cam on a
separate rotary shaft, substantially as hereinbefore described.
Fourthly. The construction and arrangement of jacquard or pattern regulating
apparatus generally in such manner as that the hooked wires shall be allowed to
remain elevated after having been lifted during any desired period of time whilst
the lifter bars continue their up-and-down movement, substantially as and for the
purpose herein before described.
Fifthly. The combination of hooked stop lever, horizontal needle r, lever
arm d', and hooked wire d, when arranged and caused to operate together,
substantially in the manner and for the purpose herein before described and
illustrated by Figures 4, 4ª, and 5 of the modified reversed arrangement thereof,
as specified.
In witness whereof, I, the said Friedrich Eduard August Büsche, have here-
unto set my hand and seal, this Fifth day of December, in the year
of our Lord One thousand eight hundred and eighty one.
