Figure 1 illustrates the manual cleaning twisting gun of the existing art. According to the known art, the apparatus composed on the one hand, a hollow body 1 comprising a spindle 2 placed inside the body 1 fixed by means of removable fixing device 3. The spindle 2 is supported by at least two bearings 4 and 4’, also a counter bearing 5. The worm gear 7 and driven gear 8 are mounted on the pin 6 as shown in the fig and the driven gear 8 is in engaged position with spindle 2, the trigger 9 is fixed out of the body and the ratchet 10 is fixed on the trigger 9. The ratchet 10 has a tooth 10’ which engages with worm gear 7 as shown in the figure, the spring tension 11 is provided for trigger 9 with one end connecting the pin and other end to trigger 9. A similar hollow body is used to close the tool which is not shown in the figure.

When the trigger 9 is actuated against the force of the spring 11, the ratchet tooth 10’ moves and comes into contact with worm gear 7 which in turn is rotated and the driven gear 8 which is connected via shaft also rotated as it engaged with spindle 2 and causes rotation of spindle 2 which removes the fluff and waste particles stricken to the machinery.

Figure 2 illustrates the electrical cleaning twisting gun of the existing art. According to the known art, the apparatus composed on the one hand, a semi-circular hollow body 12 with rib slots 13 arranged in between the body to hold the components. The charging point 14, battery 15, switch 16, Motor 17 are in series connection. The output shaft 18 of the motor 17 is connected to spindle 2 by a connector 19. The spindle 2 is supported by at least two bearings 4 and 4’ as illustrated in fig 1. A similar semi-circular hollow body is used to close the tool which is not shown in the figure.

When the switch 16 is pressed ON the power from the battery 15 is supplied to motor 17 which in turn is rotates the output shaft 18 and the connector 19 which connects it to spindle 2, causes rotation of spindle 2 which removes the fluff and waste particles stricken to the machinery.

Figure 3 illustrates multi operational mode twisting gun of the present invention. According to the present invention the twisting gun comprises the features of mechanical and electrical system as multi operational mode system. Referring more specific to figure 3 the existing electrical and mechanical system is combined and facilitated with the cam arrangement 21. The present invention provides for switching from mechanical mode to electrical mode and vice-versa. By switching the modes, the idling of the apparatus is avoided, thus increasing the efficiency of the apparatus. The said cam arrangement 21 is attached to motor 17 and the coupling arrangement 20 is attached to the output shaft of motor 18. The knob 22 which controls the coupling 20 engages and disengages action. The knob 22 configured to be rotated to turn it ‘ON’ or ‘OFF’ for switching from one mode of operation to another as desired. During the mechanical mode of operation, the knob 22 is turned off and motor 17 gets switched off and the coupling arrangement 20 gets disengaged as shown in the figure. When the trigger 9 is actuated against the force of the spring (not shown) the ratchet tooth 10’ moves and comes into contact with worm gear 7 which in turn is rotated and the driven gear 8 which is connected via shaft also rotated as it engaged with spindle 2 and causes rotation of spindle 2 which removes the fluff and waste particles stricken to the machinery in the mechanical mode of operation.

Figure 4 illustrates multi operational mode twisting gun during electrical mode. When the knob 22 is turned ON the cam 21 pushes the motor 17 which in turn makes the coupling arrangement 20 gets engaged. During this operation when the switch 16’ is turned ON the power is supplied to the motor 17 from the source of electricity (15) such as a battery which in turn rotates the spindle 2 via coupling arrangement. The spindle 2 is used for removing fluff and waste particles stricken to the machinery in the electrical mode of operation. When operating in the electrical mode the driven gear 8 automatically gets disengages from the spindle 2 to avoid damage and trigger 9 is unoperatable.

Advantages of the present invention:
• The present invention provides for switching to mechanical mode or to electrical mode as and when required by a user.
• When the user is fatigued while operating the apparatus in mechanical mode, he/she can switch to electrical mode by simply rotating the knob to turn it ‘ON’ and the apparatus will continue to remove the fluff with the help of the motor powered spindle.
• When the user is operating in electrical mode, if the source of electricity such as a battery is exhausted, he/she can switch to mechanical mode by simply rotating the knob to turn it ‘OFF’ which provides continuous operation of the apparatus.
• By simply switching modes of operation idling of the apparatus can be avoided, thus increasing the efficiency of the apparatus and helping to maintain the quality in ring spinning.
