  • Patent number: 5865394
    Abstract: A self contained bobbin winder including at least one spool rod coupled at an end thereof to a self contained housing. Each rod is adapted to removably insert within an axially aligned aperture formed in a spool of thread. At least one bobbin rod is coupled to the housing. Each bobbin rod is adapted to removably insert within an axially aligned aperture formed in a bobbin for winding thread therearound. At least one motor is adapted to rotate the bobbin upon the activation thereof. Also included is at least one switch coupled between a power source and motor. The switch has a first actuated orientation for providing power to the motors thereby rotating the bobbin rods and a deactivated orientation for precluding power from being supplied thereto. Finally, a cutoff mechanism is included to preclude operation of the device once the bobbin is fully wound with thread.
