Patent ID: 7325766

Claim:
An automatic bobbin winder system for replenishing a bobbin in a convenient and economical manner without unthreading a sewing machine comprising, in combination: a housing having a lower flat base and an upper surface with a periphery coupling the base with the upper surface to create a chamber; a motor secured within the chamber with a rotatable drive shaft extending upwardly through the upper surface; a battery removably secured within the chamber, the base consistituting a removable panel in the housing to permit access by a user to the battery for repair and replacement; electrical components including a button mounted on the upper surface with associated wires coupling the button and the motor and the battery to allow a user to selectively depress the button for energizing and de-energizing the motor to selectively start and stop the rotating of the drive shaft; removable bobbin positioned on the drive shaft above the minor surface for rotating to thereby wind a bobbin thread thereon with the starting of the motor; a generally U-shaped path on the upper surface, the path having an input end and an output end with a first linear extent beginning at the input end and a second linear extent ending at the output end with a semi-circular extent there between; and thread guides including a pair of elastomeric pads along the path adjacent to the input end for applying a restrictive force to a thread being pulled there through, the pads having resiliency and adapted to exert a force to the pads and thread there between, the guides also including a cylindrical post adjacent the midpoint of the semi-circular extent of the channel for thread guiding purposes.
