Foundation Thread.
1 GOTTHELF STEIN of 24 Blumenstrasse Berlin in the Kingdom of Prussia and
German Empire, Manufacturer do hereby declare the nature of my said invention
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
Bead work has heretofore been made either only by hand or the beads have been
sirung upon warp threads and woven. The present invention has for its object the
construction of a machine whereby threads that may serve either for the warp or for the
weft of such fabrics, are strung with beads according to a definite prescribed pattern.
These single threads of beads, which together form a definite pattern, may then be
used either for weaving in a loom or for embroidery machines and the like, or
generally in upholstery or fancy work manufacture.
The fixing or tying on of the beads is effected by the machine in such a way that
beads or other suitable perforated objects are automatically conveyed by a special
mechanism to a particular, part of a thread determined by a pattern card and are
secured in that position by a knotting mechanism.
For this purpose the beads for the separate threa is are strung upon a yarn serving
as foundation thread, which is wound upon a spool shown at a in Fig. 1. 2 and 3 of
the accompanying drawings. This thread passes from the spool or roller a over the
roller b and through the locking plate c carried by the bar C, in front of the conveyor d
which has a slot; thence it passes through the tube L of the knotting mechanism
Figs. 4 and 1 to 3 over the drawing roller f to the taking up roller g, carried by a
pivotted frame and driven by the roller in order to attain as uniform an action as
possible.
Below the rollers a and b is a third roller Figs. 1 and 2 which contains a
secondary thread, that also passes into the tube L as indicated by a dotted line, and
then passes together with the foundation thread carrying the beads on to the taking
up roller
This secondary thread is however not indispensably necessary and only
g.
serves the hetter to secure the beads.

page_text: The construction of the machine is as follows: The wheel i Figs. 1, 2 and 3 on
the crank shaft gears with the wheel on shaft and drives the wheel on the same
shaft which in its turn drives shaft n Figs. 1 and 4 having bevil wheels at both ends.
This shaft drives by means of its bevil wheels the fixing or tying mechanism situated
on the vertical tube L Figs. 1. 2. 3 and 4.
This consists of two flyers oo¹ rotating in contrary directions and having tubular bosses
and a pin for the reception of the thread reel j. The boss ẞ of the upper flyer o revolves
upon the tube Land receives its motion from the lower conical wheel ¹, while the boss S
of the lower flyer o revolves upon the boss ẞ and also carries a bevil wheel k² at its end.
By this arrangement the two flyers are made to revolve in contrary directions so that
each bead is secured by a crossed thread. The desired pattern is punched upon card
strips like those of a Jacquard apparatus, which are fixed side by side in any desired
number upon the drum Figs. 1 to 3, which is rotated by the shaft » situated above
it. The Jacquard holes may also be formed otherwise upon the drum, as for example
they may be holes or recesses directly on the metal surface thereof. In the case of
broad fabrics and long patterns to be produced, the drum might become too large and
in that case the usual Jacquard apparatus may be employed without causing any
difficulty.
The wheel Fig. 2 and 3 gears with wheel u on the axis of which is a wheel w
having eight tappets which act successively upon a stud z on a lever a pivotted at A.
and having at its free end a finger y the end of which bears upon the surface of the
drum t so that when in the descent of the lever by its own weight one of the holes
of the cards happens to come opposite the finger y, it allows this to pass through so
that the lever can descend lower than is otherwise possible, and can then act upon the
short arm of an elbow lever B the long arm of which is connected to a bar
carrying the locking plate e so that as the short arm of B is depressed by the lever x its
long arin is made to move the bar C with the locking plate to the left, while when the
lever arises, a spring moves these parts to the right again. The locking plate
shewn detached at Fig. 5-6 and 7 has at its underside two slit-iongues D D' adjustable
by set screws in order to be applicable to beads of different sizes. When moved as
indicated, the upper slit tongue D separates a bead on the thread at each to and fro
urovement; on its moving from left to right the lowest bead on the thread passes
through the widened end of the slot of D on to the lower tongue D', while on moving
from right to left the bead on tongue D¹ is first separated by D from the other
beads on the thread and then falls from the widened end of D' slot under the
holder which seizes it and leads it into the fixed tube L of the tying mechanism
whereupon the bead is at once, tied in position underneath d by the two threads of
the flyers o and o'.
The conveyor d has two motions; the one is that shewn at Fig. 2. 8, 9 and 10
namely a forward motion for seizing the bead, and a downward motion for bringing
the bead into the tube.
These motions are effected as follows: the conveyors d are fixed on an upper bar s
which slides on transverse pins in the forks F on a lower bar s² which is capable
of rocking on trunnions at its ends. The bar s₁ has a vertical arm connected by
link N to a lever M fixed on a rocking bar L¹ on the one end of which is fixed an
arm H, that is drawn against studs on a disc G revolving with the shaft v.
Thus on
the rotation of G its studs push the arm H backwards causing M and N first to slide s'
and consequently the conveyers d forward, until s butts against F whereupon the
further motion of M causes to rock, thus imparting to d its downward motion.
the arm H being released by the stud of G the spring J¹ brings it as also L' and M
back into their original position, and a light spring J also moves s' with the conveyors
back again.
Un'
The machine consequently operates as follows: Part of the beads coming from a
are placed above the locking plate e in order to facilitate the falling of the single
beads. The crank shaft being rotated, the flyers have continuous motion imparted to
them, and the conveyors will also receive their compound motion continuously, but
the locking plate c will only effect the separation of a bead from the pile above it

pattern cards.
now particularly described and
this
Having
of
ascertained the nature
invention and in what manner the same is to be performed, I declare that what I
claim is:
1. In machinery for fixing beads or similar perforated bodies upon one or more
foundation threads according to a definite pattern the combination of a locking plate
for separating the beads singly from a row thereof on the upper part of the thread the
action of which locking plate is regulated by a pattern card or Jacquard apparatus a
conveyor for conveying the separated bead down the thread into a tube and a fixing or
tying mechanism, consisting of two fleyers that twist two threads round the founda-
tion thread so as to tie the bead in the position in which it has been placed by the
conveyor, substantially as herein described with reference to the accompanying
drawings.
2. In machinery for fixing beads upon one or more foundation threads the use of a
tying mechanism for fixing the beads in position, consisting of a tube through which
the beaded thread passes and on which are mounted the tubular bosses two flyers
carrying reels of thread, the flyers being made to rotate in contrary directions so as to
twist the threads upon the foundation thread and thus secure the beads in position
thereon substantially as herein described.
3. In machinery for fixing beads on one or more foundation threads, the use of
locking mechanism consisting of two slotted tongues arranged one above the other
upon a plate receiving a to and fro motion in accordance with the holes upon a
pattern card of Jacquard apparatus the slotted ends of the tongues being arranged in
opposite directions, so that when moving in one direction the upper tongue liberates
a bead from its slot and allows it to fall on to the lower tongue, while on moving in
the contrary direction, the bead on the lower tongue is liberated by its slot, while the
upper tongue at the same time passes underneath and holds another bead on the thread,
substantially as herein described.
4. The machinery for fixing beads on one or more foundation threads the use of a
conveying mechanism, consisting of a slotted arm carried by a sliding bar which in
its turn is carried by a rocking bar, so that by the movement of the first bar the arm
is advanced so as to embrace the foundation thread while by the movement of the
second bar, it is moved downwards so as to push the bead below it down to the fixing
apparatus, substantially as herein described.
