in the Empire of Germany, Manufacturer, for the Invention of "IMPROVE-
MENTS IN MACHINERY OR APPARATUS FOR THE MANUFACTURE OF BRAIDS."

PROVISIONAL SPECIFICATION left by the said Friedrich Eduard August
Büsche at the Office of the Commissioners of Patents on the 21st November
1879.
FRIEDRICH EDUARD AUGUST BÜSCHE, of Schwelm, Westphalia, in the Empire of
Germany, Manufacturer. "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR THE
MANUFACTURE OF BRAIDS."
This Invention relates to a peculiar construction and arrangement of what are
commonly known as braiding machines, & has for its object the enabling such
machines to be worked at a higher speed than heretofore, & affording a more ready
means of adjustment for making braids of different widths & patterns in one & the
same machine by the employment of certain parts, which are interchangeable, &
kept in reserve, so as to adapt the machine to the particular kind of braid or braids
to be produced.
In carrying out my Invention I provide the bottom or base plate of the braiding
machine with openings, the number & position of which correspond to the number
& position of the notched disc wheels which the machine is intended to contain, &
in some or all of these openings I introduce a metal or other holder or bush, within
which again there is accurately fitted a second or inner holder or bush, which is
easily removeable and interchangeable for the purpose hereinafter explained. If
desired this inner holder or bush may be fitted direct into the bottom or base plate,
but I prefer the arrangement above set forth. These removeable & interchangeable
holders serve to carry the pivots for the notched disc wheels (similar to those used
in German braiding machines), which I employ for carrying & imparting the
travelling motion to the bobbin carriers. Where these interchangeable holders are
not provided the pivots will be fitted to the base plate in the usual manner. The
said inner holders are so adapted as to enable the pivots (& their wheels) fitted
thereon to be brought nearer together or farther apart, as may be required, for

page_text: the grouping of the series of bobbin carriers into subdivisions, according to the
different widths & patterns of braids to be produced, provision being made for
adapting the usual thread guides to each group or subdivision of the entire series
of bobbin carriers.
In order to maintain the bobbin carriers perfectly steady I provide them with
two or more special supporting plates or flanges, resting either upon the toothed
wheel & notched disc, or upon the notched disc only, or upon a separate disc in
conjunction with the toothed wheel, thus affording a vertical support whilst the
lateral support is obtained by a fixed guide circle on the one side, & the arrange-
ment of wheel & notched disc on the other. This guide circle is composed of
a number of separate removeable & interchangeable plates or segments so arranged as
to be readily changed in correspondence with the before mentioned interchangeable
bushes in the bed plate, & adapted to the particular arrangement of notched disc
wheels to be employed. I also employ a peculiar self acting stop arrangement for
stopping the machine on the breakage of a thread, which consists in providing a
transverse pin held up by a spring situate near the bottom of each bobbin carrier, so
that when the thread tension weight falls, the spring will be deflected, & allow the
pin to descend & be brought within range of the end of an adjustable arm sliding
longitudinally, and connected with the general engaging & digengaging gear of the
machine, consequently as the travelling motion of the bobbin carrier proceeds, the
said pin will force the said arm inwards, & so stop the machine by any of the well
known arrangements. This stop pin may either be separate & distinct from the
'weight or be connected therewith either directly or indirectly.
In order to enable the machine to work in a proper manner at a higher speed
than heretofore, I combine metal or other springs with the tension weights in
such a manner that the spring shall be free to act independently of the weight in
cases where the inert force of the weight would prevent it from descending.
I also employ a self adjusting sliding thread guide in the upper part of the
bobbin carrier in order to ensure a more even & regular winding of the thread
from the bobbin under all circumstances.
In cases where patterns of braids are required involving complex motions of the
bobbin carriers, I propose to employ a fixed slotted guide plate situate beneath the
spur wheels of the notched discs, & to provide notches in the said spur wheels for
the reception of the lower portion of each bobbin carrier, thus allowing the bobbin
carriers to be guided by the lower slotted guide plate whilst deriving its lateral
support from a guide circle.

the said Friedrich Eduard August Büsche in the Great Seal Patent Office on
the 21st May 1880.
FRIEDRICH EDUARD AUGUST BÜSCHE, of Schwelm, Westphalia, in the Empire of
Germany, Manufacturer. "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR THE
MANUFACTURE OF BRAIDS."
My said Invention relates, first, to a peculiar combination and arrangement of
tension weight and spring to be used in connection with the bobbin carriers of braid
making machines, whereby I am enabled to work such machines in a satisfactory
and proper manner at a higher speed than heretofore.
4
Secondly. To a peculiar arrangement of self adjusting sliding thread guide to be
adapted to the upper part of the bobbin carriers, whereby I ensure a more even
and regular unwinding of the thread from the bobbins under all circumstances.
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 Figures.
Figure 1 of my Drawings is a vertical section of a bobbin carrier and bobbin, showing
the application thereto of my improved combined tension weight and spring, and also
of my improved self adjusting sliding thread guide; Figure 2 is a side elevation
corresponding to Figure 1; Figure 3 is a plan and partial section taken along the
line 1-2 in Figure 1; Figure 4 is an enlarged sectional elevation of my improved
combined spring and weight, and portion of the bobbin carrier, and Figure is a
horizontal section taken along the line 3-4 in Figure 4.
In these Figures a is the bobbin, and b the hollow bobbin carrier, to which is
attached the upright arm c, having the usual catch lever d hinged to its upper
end; e, e¹, are the usual thread guide eyes; f is the tension weight, the upper end
of which is, by preference, made hollow to receive the rod g, with its enlarged
shoulder or collar formed thereon, and the helical spring h, which bears at its lower
end against the said enlargement or other fixed point in the rod whilst the upper
end of the said spring bears against any fixed point i above in the said weight.
The gravity of the weight is sufficient to maintain the spring fully or nearly
compressed, so long as the weight is suspended by the rod g, which is hung from
the thread by an eye in the upper end of such rod, as is clearly shown in Figure 1.
I am aware that it has been proposed to combine springs with the tension weights
used in braid making machines, but the manner of effecting such combination was
not adapted to produce the peculiar beneficial effect which I obtain, for the reason that
in such former combinations the spring could not act without acting upon the weight,
and influencing the action of the same, whilst by my mode of combining the weight
and spring, the spring is allowed to act independently of the weight when the bobbin
carrier passes through the inner circle, and is driven at such a speed as to prevent
the weight from acting by reason of its inert force. In this case the spring by its
reaction will always take up the slack of the thread, at the same time allowing the
weight to perform its proper function without any sudden strain on the thread when
the bobbin carrier returns to the outer circle.
In order to facilitate the unwinding of the thread in a regular manner from off
the bobbin when the machine is running at a high speed, I employ a peculiar self
adjusting sliding thread guide, which I shall now proceed to describe. This guide
consists of a piece of metal k, sliding freely in a vertical slot l, made in the upright
arm c of the bobbin carrier, such slide being provided with a thread eye at its
upper part, as shown clearly in my Drawings. The thread passes direct from the
bobbin a through the eye in the sliding thread guide k, thence upwards and
through the eye e in the top of the slotted arm c, downwards through an eye
in the catch lever d, thence through the eye in the upper end of the tension rod g,

page_text: and up through the eye e¹ in the top of the bobbin carrier, as is well understood.
The weight of the sliding thread guide k is such as to maintain the thread always at
right angles to the bobbin whilst unwinding, thus ensuring a more smooth and
uniform unwinding of the thread from off the bobbin.
Having now described and particularly ascertained the nature of my said 5
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 peculiar combination and arrangement of tension spring and weight, 1
as and for the purpose herein before described and illustrated by my Drawings.
Secondly. The peculiar arrangement of self adjusting sliding thread guide, 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 Thirteenth day of May, in the year of 1
our Lord One thousand eight hundred and eighty.
