DESCRIPTION
FIELD OF INVENTION
This invention relates to a loom for weaving which is a modification on the traditional "Throw Loom with Fly Shuttle and Foot Treadle" commonly known as Handloom. It can function automatically or can be used manually as set by the user and thus serves better features for a weaver. It can be used at places where traditional handloom are still used where weft designs are done and also to train new weavers about traditional hand weaving techniques. Besides, at places where there are frequent power cuts, this invention can provide uninterrupted weaving.
PRIOR ART AND PROBLEM TO BE SOLVED ..
A traditional handloom was a necessity of a household in the past and is still in many areas of the world but notably in the north-eastern region of India. During festivals, giving homemade articles produced from the handloom as a sign of respect and gift was a ritual. In the state of Assam, during the Assamese festival- Bihu, presenting a hand-woven - Gamochq to others is a ritual. The same is also used as gift for guests and to welcome people besides using as a body wipe or informal wearing as a cloth. Also, during a wedding, hand-woven Mekhela Chadar are used for the bride and shirts for the groom. Such garments are woven at home in the traditional handloom known as Taat Xaal i.e. "Throw Loom with Fly Shuttle and Foot Treadle" which is widespread in the state of Assam and other regions of India. Such looms are manual in operation and requires the weaver to skillfully use both the hands and feet in synchronization- a traditional knowledge passed on to generations from centuries. They provide the weaver complete control on the weft density of the fabric and the ability to create weft designs known as Phools. They are often referred to as "Handloom" because of being complete manual in nature. However, this home production and such traditional practices is declining at an alarming rate due to the introduction of power looms in the production of such materials. Power looms are a boon to meet huge demands but to acquire it for a household as traditional necessity is tough due to lack of the 'hand woven' feel, high cost and complex automation. Besides, the traditional skill of weaving cannot be taught in a power loom; the skill which has increasing demands as hand woven clothing sells as a premium in the world.

Many patents provide semi-automatic and combined power and handlooms. In IN39304, a Semi-Automatic Weaving Loom is disclosed that is operated by hand and feet but does not provide full automation. Also, this loom differs in lifting system of warp and picking system of shuttle. In US 1763111, a Combined Power and Handloom is disclosed. But it does not match with the comfort of the traditional Handloom and involves use of advanced components and parts thus demanding higher production cost.
So, there is a necessity of the said traditional Handloom being automated to meet higher production rates but also being able to be operated in manual mode for creating weft designs and also train weavers about the traditional weaving skills.
This invention solves.the problems and meets the requirement as cited above. It is a modification on the traditional Handloom known as Taat Xaal i.e. "Throw Loom with Fly Shuttle and Foot Treadle" which is widespread in the state of Assam and other regions of India. It provides complete automation to the said Handloom but with the ability to convert back to manual mode when desired. This enables the weaver for faster automatic weaving of the fabric when desired or operate in manual mode to create weft designs or even provide training of weaving to the generations- a tradition for centuries. Besides, during power cuts weaving can continue uninterrupted. It uses simple components for lower cost of production. It can operate at a maximum of 120 Picks / minute and features automatic adjustable take-up system.
OBJECTS OF THE INVENTION
It has already been proposed that traditional handlooms allow for total manual control and facilitate hand-made weft designs but lack in weaving speed. On the other hand, power looms provide faster weaving but does not facilitate manual control.
The principal object of the invention is to provide a loom that can function automatically like a power loom or can be used manually like a traditional handloom thus providing the benefits of both the forms.
Another object of the invention is to provide a loom where weaving occurs faster when there is electricity for powering it but can be used in manual mode for uninterrupted weaving when there is a power cut or for creating weft designs or training weavers about the traditional weaving skills.

SUMMARY OF THE INVENTION
The Automated Handloom is a modification of the traditional handloom known as Taat
Xaal i.e. "Throw Loom with Fly Shuttle and Foot Treadle" which is widespread in the state of Assam and other regions of India and commonly known as "Handloom". Such a traditional handloom is manually operated and thus requires skill and experience. But it is slow in output as compared to power looms. However, hand weft designs can be made there, which has higher value. Besides, the tradition of weaving can be taught to next generations. Such a handloom is not affected by power cuts. Power looms on the other hand have high output but requires continuous power supply and lack the 'hand-made' feel and hand weft designs cannot be made. The invention provides best of the both worlds. It can operate automatically with a driving Motor(18) like a power loom and thus increase output. But when desired, it can be changed back to manual mode like the traditional handloom. The Automated Handloom comprises of a Handloom(l) having a Frame(15) where the Batten(6) is mounted. There are the Heddles(24) connected by Shedding Pedals(20) at the bottom. There is a Warp beam- let off(2) that supplies the warp yarn and Cloth roll- take up(12) that acquires weaved fabric- both mounted to the Frame(15). There is a Battening Drive System to drive the Batten(6), a Shedding Drive System that controls the Heddles(24) to create the shed, a Picking Drive System to create picking of a shuttle between the Shuttle Boxes(27) through the shed and a Cloth Roll-Take Up Drive System that provides automatic take up of completed fabric on the Cloth roll- take up(12) where the warp yarns is provided by the Warp beam-let off(2). All the above systems are automated by a Motor Drive Assembly. In automatic mode, turning on the motor allows it to weave continuously up to 120 picks per minute. It can be converted to manual mode by disconnecting the Shedding Pedal Propellers(28), removing the Lever(8) removing the Cable(16) and connecting the rope that is used in traditional loom to connect at the pickers, to the Shuttle Pushers(23). This process takes about a minute
and is easy for a weaver to perform:

DETAILED DESCRIPTION OF THE INVENTION
The Automated Handloom comprises of a Handloom(l) which is the traditional
Handloom known as Taat Xaal i.e. "Throw Loom with Fly Shuttle and Foot Treadle"
which is widespread in the state of Assam and other regions of India. The Handloom(l)
has a Frame(15) where the Batten(6) is mounted with the ability to perform the battening
motion. The Batten(6) has a Reed(25) through which the warp yarn passes and a shuttle movement channel. There are the Heddles(24) supported by Alternators(5) being
mounted to the Frame(15), and are connected by Shedding Pedals(20) at the bottom.
There is a Warp beam- let off(2) that supplies the warp yarn and Cloth roll- take up(12)
that acquires weaved fabric both mounted to the Frame(15).
The improvement involves addition of a Battening Drive System to drive the Batten(6), a Shedding Drive System that controls the Heddles(24) to create the shed, a Picking Drive System to create picking of a shuttle between the Shuttle Boxes(27) through the shed and a Cloth Roll-Take Up Drive System that provides automatic take up
of completed fabric on the Cloth roll- take up(12) where the warp yarns is provided by
the Warp beam-let off(2). All the above systems are automated by a Motor Drive Assembly. All of the above additions create the Automated Handloom.
Now, the Motor Drive Assembly comprises of a Motor(18), Shaft(10), Pulley(4) and a Primary Gear(9). The Motor(18) is a 0.5HP motor that drives the Shaft(10) by a Belt(3). to a Pulley(4). The Pulley(4) is attached at the said Shaft(10). There is also a Primary Gear(9) that is mounted to the Shaft(10). The Shaft(10) and the Motor(18) are mounted to the Frame(15). The size of the Pulley(4) to be used depends on the output drive pulley and the operating rpm of the Motor(18). So, the Pulley(4) is so chosen that the Shaft(10) rotates at 75 to 120rpm. The Primary Gear(9) attached at the Shaft(10) daves a Secondary Gear(l 1) which in turn is attached at a Secondary Shaft(17). Here, the gesar ratio of the Primary Gear(9) to the Secondary Gear(l 1) is 2:1 i.e. when the Shaft(10)
rbtates one rotation, the Secondary Shaft(17) rotates a half rotation. The Secondary
Shaft(17) is also mounted to the Frame(15) and is below and parallel to the Shaft(10). The Warp beam- let off(2) is kept under tension by a torque spring so that the
tension of the warp is maintained at all times.

The Cloth Roll-Take Up Drive System comprises of Increment Gear(7), Reducing
Gear(13), Cloth Roll Gear(22) and Cloth Roll lever(14). The Increment Gear(7) is a
coentric gear mounted to the Frame(15). Its outer gear has 100 saw teeth that facilitates
its incremental rotation by an arc motion of a lever pushing on the saw teeth. However,
the inner gear teeth varies from 26-35 numbers depending on the desired weft density. The Reducing Gear(13) is also a concentric gear mounted to the Frame(15). Its outer gear has 88 teeth and inner gear has 15 teeth. Its outer gear connects to the inner gear of the Increment Gear(7) and its inner gear connects to the Cloth Roll Gear(22). The Cloth Roll Gear(22) is mounted at the shaft of the Cloth roll take-up(12) and has 88 teeth. The Cloth Roll Lever(14) is a pivoted lever mounted to the Frame(15) whose one end is pushed down by the Lever(8) wherithe Batten(6) reaches the Fell(33) and then the other end pushes up at the saw teeth of the Increment Gear(7). The oscillation of the Cloth Roll Lever(14) can be limited by a Nut-bolt(26) pair placed below it. When the Nut-bolt(26) is fully lengthened, the Cloth Roll Lever(14) is limited to create only one increment of the Increment Gear(7) per oscillation. This increases the density of the weft yarns of the fabric to the maximum. On the other hand, shortening the Nut-bolt(26) decreases the density of the weft yarns of the fabric. The Nut-bolt(26) can thus be adjusted as per requirement of the weft density. If the range of adjustment of the Nut-bolt(26) does not meet the desired weft density, the Increment Gear(7) can be changed having different number of inner gear teeth.
The Shedding Drive System comprises of Shedding Pedal Propellers(28) that are attached on the Secondary Shaft(17). They are rods attached perpendicularly on the said shaft at the middle in opposite vertical direction aligned to the respective Shedding Pedals(20). With the rotation of the said shaft, the said propellers push their respective Shedding Pedals(20) alternately. Thus, rotation of the Secondary Shaft(17) creates shedding of the warp yarns alternately.
The Picking Drive System comprises of Shuttle Boxes(27), Shuttle Pushers(23),
Cable(16), Picking Pedals(21), Pulley Guides(29) and Picking Pedal Propellers(19). The Shuttle Boxes(27) comprise of the Picker(30) which is made of leather and has a hole in it It moves in a groove inside the Shuttle Boxes(27) along the shuttle movement axis.
The Shuttle Boxes(27) also has a gap in the base that is parallel to the said groove. The

Shuttle Pushers(23) are flattened rods having a pivot and mounted to the Batten(6). The long end of the Shuttle Pushers(23) pass through the hole in the Picker(30) an then through the gap of their respective Shuttle Boxes(27) and emerges a little portion below. There is a Plate(34) at the side of the Shuttle Boxes(27) and forms a part of that face and is held by a Tension Lever(31). The Plate(34) receives and holds the shuttle in place. The Cable(16) connects the Shuttle Pushers(23) and to Picking Pedals(21). The Picking Pedal Propellers(19) are rods attached perpendicularly on the Secondary Shaft(17) at both the ends in opposite vertical direction. When the Secondary Shaft(17) rotates, the Picking Pedal Propellers(19) push their respective Picking Pedals(21), alternately. When the Picking Pedals(21) are pushed, through the respective Cables(16), the respective Shuttle Pusher(23) is pulled arid the shuttle present in that respective Shuttle Box(27) is propelled to the other end.
The Battening Drive System comprises of two 'L' shaped Levers(8) attached and
pivoted at the lower body of the Batten(6) at both the sides. The said Levers(8) connect
to the Shaft(10) by a Crank(32) -mechanism that transforms the rotation of the Shaft(10)
to battening motion to the Batten(6). At the end where the Cloth Roll-Take Up Drive
System is present, the Lever(8) also pushes the Cloth Roll Lever(14) when the Batten(6)
is fully towards the Cloth roll- take up(12). Thus, when the Shaft(10) rotates, battening
motion is produced in the Batten(6). The three functions viz. Shedding, Picking and Battening are completed during
one complete rotation of the Shaft (10) and half rotation of the Secondary Shaft (17)
respectively. The picking of the next weft will be completed during the next half rotation
of'the Secondary Shaft (17). The functions covered during one complete rotation of the
Shaft (10) is said to be "One Beat". During one beat, the Cloth roll take-up(12) is also
rotated simultaneously by the Batten (6) through the Cloth Roll Lever (14) by the Cloth
Roll-Take Up Drive System(12x). One complete rotation of the Shaft(10) creates one
pick. Hence, as the Shaft(10) can be operated at a maximum of 120rpm, the loom can
operate at a maximum of 120 picks per minute. The setting of timing of Shedding, Picking and Battening is crucial in this loom.
To do that, at first the Primary Gear(9) is fitted and Crank(32) of the Levers(8) is brought
in such a position that the it remains vertical at the top most position. Let this position be

"Zero" (0). While working, the Primary Gear(9) rotates anti-clock wise (as viewed from
right side of the loom). The whole or full one rotation of the Primary Gear(9) is 360
degrees. Let the other seven position of the Crank(32) be from l(one) to 7(seven) at an
interval of 45 degrees(Figure 3). When the Crank(32) is at '0' position, the Shedding
Paddles (20) will remain at same height, the Alternators (5) will remain parallel to the
horizon, all warps will remain at a horizontal plane and the Batten(6) will remain
pierpendicular to the horizon. When the Crank(32) is at position T the Shedding
Paddles(20) are ready to move (one up, other down) causing the alternators (5) ready to move for splitting the alternate warps up and down. When the Crank(32) is at position
'2', the Batten(6) keeps the' previously weaved weft nearest to the cloth. The Cloth Roll
Leyer(14) is driven by the'Batten(6) to move the Cloth Roll- take up(12). In this position
the warps are split moderately and will open fully when the Crank(32) reaches the
position '3'. Here, the warps remain fully split until the Crank(32) reaches the position
'5'. When the Crank(32) crosses the position '4' the shuttle moves from one Shuttle
Box(27) to the other, before the Crank(32) reaches the position '6'. When the Crank(32)
is at '6' position the Batten(6) goes farthest away and starts to come near and reaches the
perpendicular position to the horizon. During the whole operation the Secondary
Gear(11) rotates only 180degrees and once more the same steps are repeated except the
movement of Shedding Paddles(20). Now the Shedding Paddles(20) move in opposite
direction and the other Peaking Cable(16) of the other side will work at this time,
Alternator(5) will move in opposite direction as well as the shuttle will also be launched back.
To convert the loom to manual mode for manual weaving or designing with the
help of J-Card Machine i.e. using Dobi, the Shedding Pedals(20) are pushed aside so that
the Shedding Pedal Propellers(28) do not touch them or Shedding Pedal Propellers(28)
are removed. Next, the Batten(6) is disconnected from the Shaft(lO) by removing the
Lever(8) and the Cable(16) may be removed. The rope that is used in traditional loom to
connect at the pickers is now connected at the Shuttle Pushers(23). Now the loom can be
operated in manual mode. This process takes about one minute and is easy for a weaver
to perform.
