FRIEDRICH EDUARD AUGUST BUSCHE, 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 for machines
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 my Invention 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 regu-
lating 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 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, 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 machines.
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

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 employ as many
repeats of the said pattern apparatus as there are main or principal notched disc
wheels in the braiding machine. 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.
