Eri Spinning Machine.
This invention relates to improvement in device for spinning of Eri.
Traditional system of spinning of Eri to produce Eri thread is prevalent in
village areas. In this method, spinning of Eri is done by rotating a reel ie. a small spindle
connected to a small wheel. The rotation of the reel is done by hand. It is extremely
cumbersome for a weaver to rotate the reel by hand after every interval of time.
There have been many proposals to spin the Eri thread but these are
unable to full fill the conditions for providing the desired level of spin to the thread. For
example- One previous device proposes for spinning Eri thread. But, remarkably, before
completion of the spinning of the thread, it starts storing the loosely spinned thread on a
small spindle ie. called Mohura and such loosely spinned threads are unsuitable for weaving
clothes. So, these proposals have the disadvantage.
These problems are overcome by the present invention which provides
desired level of spin to the Eri thread. This machine comprises of Foot rest, wheels, spindles,
ball bearings wooden or metallic frame, metallic bow having rubber belt, engagement clips
for fastening the spindle or Mohura, small iron bars and a key.
In one form of the invention, the spindle having 'U' shape at its middle
portion comprises of a small wheel having an engagement clip, a small iron bar for keeping
small spindle ie Mohura and another engagement clip attached to rear end of 'U'shape. Also,
having small hole along the front end of the spindle through which Eri thread passes.
In another form of the invention, comprises of a wooden or metallic frame,
a large wheel, foot rest connected to large wheel, "T" shape iron strip connected to the end of
the axle of the large wheel.
And also, there is a lever arrangement comprises of two nos. of iron bar, a
small bow made of metal having rubber belt which gives the reverse motion of the small
wheel fitted inside the 'U' shape of the spindle with the help of lever assembly.
Referring to FIG. 1 can be seen that the Endi spinning machine, according
to this invention comprises a large wheel (W1), Spindle (S1) having "U" shape at its middle
portion. A small hole and an engagement clip(C1) are provided inside the front and rear end
of "U" shape respectively for keeping Mohura in between with the help of a small iron bar
(B2). Another small hole(H) is made along the front end of the spindle (S1) through which
the thread passes. There is a groove inside the "U" shape where a small wheel (W2) having
an engagement clip (C2) is fitted which allows to revolve the wheel in a certain direction. A
guider(G) for Eri thread is attached to the back side of the 'U' shape of the spindle. This
spindle is fitted to a wooden or metallic frame(F) with bearings. The large wheel (W1) is also
fitted to the main frame(F) just below the spindle with two nos. of bearing and a key(K). An
iron strip (T) adjustable in height is attached to the end of the axle (A) of the large wheel. A

long iron bar (B3) is fitted behind the frame so that the lower end touches the 'T' strip. A
small metallic bow(Bo) having rubber belt (R) is attached to the frame just near the spindle
by pointing the bow towards the smaller wheel (W2). The upper ends of the metallic bow
(Bo) and the long bar (B3) are connected with a small bar (B1). A foot rest (FR) is connected
to the larger wheel (W1) with a small connecting rod (CR). The larger wheel (W1) is
connected with the spindle with a rope where the spindle acts as a small wheel.
FIG.2. Shows the Eri spinning machine in operation. When the large wheel (Wl) is rotated
with the help of foot rest (FR), the spindle acts as a small wheel starts revolving. The
unspinned raw fibre of the Eri being passed through the hole of the spindle and guider (G) is
fastened to the small spindle (S2) ie called Mohura. The revolution of such spindle starts
spinning to the Eri thread and it continues till it completes one revolution by the larger wheel
(W1). After completion of one revolution by the larger wheel (W1), the iron strip (T) fitted
on its axle pushes away the lower end of the connecting rod as a result the top end moves
away in opposite direction giving the rubber belt of the bow just to touch the small wheel
(W2) and then the small wheel revolves in reverse direction for a moment making store of
the spinned thread on the Mohura already attached to the spindle (S1) without hampering the
overall revolution of it. This way, the desired level of spinned thread is stored on Mohura
once after every revolution of the larger wheel (W1). The highest advantage of this machine
is that it gives sufficient time to spin the Eri thread as the Mohura waits for storing the
spinned thread till it completes one revolution by the larger wheel (W1). Supposing the raw
thread is spinned 40 times against every revolution of the larger wheel (W1). While operating
the machine if we don't allow the already spinned thread to store on Mohura, the rubber belt
easily slips on small wheel (W2) and unable to revolve it for which it will get one more
chance to spin the thread 40 times before storing thread. So, with this machine, we can easily
provide desired level of spin to the raw thread which is very suitable for weaving clothes.
ABSTRACT:-
It is very useful for spinning raw thread of Eri to the desired level. This
machine comprises of a wooden or metallic frame, spindle (S1) with a clip(C1), a large
wheel (W1) with an axle (A), a small wheel (W2) with an engagement clip (C2), metallic
bow (Bo) with a rubber belt (R), small iron bars (B1,B2, B3), foot rest (FR) and a key (K)
used for fixing the larger wheel (Wl) to the main frame. By using this machine, the raw
thread of Eri can be spinned to the required level and stored on Mohura for further use.
