I CARL ENGSBERG, HERMANN MÜLLER and CARL SPEISER all of Nuremberg
in the Kingdom of Bavaria & Empire of Germany Manufacturers do hereby declare
the nature of this invention and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement:-.
This Invention has for its object simplifying and improving the manufacture of
twisted fringes by means of looms or apparatus which complete the manufactured
article by one operation as hereinafter explained-The fringe is twisted by a
rotating hook which is caused to engage with loops formed in the fringe thread
which is interwoven with a suitable number of warp threads to form the edging
or fabric from which the fringe depends.

Figure 1 of the accompanying drawings represents in plan and figure 2 in
vertical section of the same mechanism constructed or arranged according to this
Invention.
Figure 3 is a front view of a modified arrangement-Figure 4 is a plan of the
mechanism employed in this modification and Figure 5 is a vertical section of the
same.
K, K Figures 1 and 2 represent the longitudinal or warp threads and 7 is a
shuttle or bobbin carrier working in a race in a lathe or batten m forming part of
a loom or apparatus such as is commonly employed for weaving narrow fabrics
such as braid edgings and the like-The twisted fringe is produced according to
this Invention by providing the loom with a rack a a to which a reciprocating
motion is imparted by means of a lever c operated by a cord d connected to a
lever e provided with a friction roller f acted on by a cam or tappet g, the return
motion of the rack being produced by a spring h connected to the rack a by a
cord i whereby a rapid movement of rotation is imparted to a pinion n on a spindle
one end of which is bent at right angles so as to form a twisting hook o.
The twisted fringe is produced simultaneously with the weaving of the band,
the weft thread in the shuttle also forming the fringe thread-When the shuttle
with its spool has moved through the open shed from left to right the fringing
thread is laid hold of by the hook o as the spool is drawn back. Figure 1 shews
the parts in this position-Before the shuttle reaches the end of its travel towards

page_text: the left hand side, the pinion n and hook o begin to rotate and complete the
twisting of the fringe by the time the shuttle has completed its motion towards
the left. At the same time the batten beats up the weft and by means of a pin p
disengages the twisted loop of fringe from the hook o by which it has thus been
twisted Whilst the batten then retires to its original position and whilst the
shuttle again passes through the warp the rack a is drawn back to its former
position A wire qr is placed over the pinion n in order that the pinion teeth
may not become entangled with the fringe.
Figures 3 to 5 illustrate a somewhat modified construction of the mechanism
herein before described-The fringe thread also forms the weft and is not carried
by a shuttle as in the arrangement previously described, but passes from a spool A
in a direction parallel with the warp and over a guide roller B to a book D arranged
on the batten and employed in place of the shuttle-This hook has á motion like
that of the shuttle figures 1 and 2.
When the hook D moves from left to right it draws the fringe thread in front of
the guide roller B and forms a loop between the roller B. and the completed
portion of the fringe band at C. figure 4 As the hook D moves back from right
to left during which motion the thread is maintained tant the loop is transferred
to a hook o connected to a pinion n and is twisted by the action of a rack a as
described with reference to figures 1 and 2-For throwing off the completed fringe
from the wire book o a lever E figure 5 is employed which by means of a cam
or tappet M acting on a friction roller N on a lever L operating the lever E by
the intervention of a lever J and cords K. H (the upward motion of the lever E
being produced by means of a spring F and cord g) is caused to oscillate upwards
and downwards at the necessary intervals.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
we claim is
First. In a loom or apparatus for making edgings or fabrics with twisted
fringes formed from loops of a thread interwoven with suitable warp threads
a revolving hook for twisting the loops arranged and operating substantially as
hereinbefore described with reference to the accompanying drawings.
Second. The arrangements and combinations of parts constituting the apparatus
herein before described and illustrated by Figures 1 and 2 and Figures 3. 4 and 5
of the accompanying drawings for the purpose specified.
