  • ABSTRACT A sewing machine so designed as to cause an arm shaft to be subject to different drive controls according to the operating position of a selection knob, though a controller may be continuously depressed in the same manner, wherein, under the first operating position of the knob, the depression of the controller effects continuous normal stitching and the release of the controller brings the'arm shaft to rest at a predetermined angular position; under the second operating position of the knob, the depression of the controller causes the arm shaft to make one rotation and be brought to rest at a predetermined angular position regardless of the succession of the depression of the controller; and under the third operating position of the knob, the bobbin winder is actuated with the arm shaft kept inoperative at a predetermined angular position independently of the depression of the controller.
  • SEWING MACHINE WITH A NEEDLE POSITIONING DEVICE This invention relates to a sewing machine capable of resting the arm shaft at a predetermined angular position thereof and more particularly to a household sewing machine. It is a well-known process to automatically bring, upon completion of sewing, the arm shaft to rest at a predetermined angular position, for example, with the needle positioned above a work fabric. A device for carrying out said process is generally referred to as a needle positioning device.
  • this device With a household sewing machine, however, this device has not yet been made commercially available, except for a few cases. This may be due to, among other things, excessive cost, complicated operation and insufficient structural durability. Particularly, the fact that the cost of providing said needle positioning device is too high for the value derived from its use poses the most difficult problem to resolve.
  • said needle positioning device comprises a first electric circuit for driving the motor at a speed according to the manner in which the controller is depressed; a second electric circuit for operating the motor at a fixed low speed when the controller is released from depression; and switch means for deenergizing the second electric circuit when the arm shaft is brought to rest at a predetermined angular position. From the viewpoint of utility value, however, said needle positioning device is still too expensive to be deemed fully successful in terms of cost.
  • This invention relates to a sewing machine and more particularly to a needle poitioning device for a household sewing machine, said device being so designed as to cause the arm shaft of the machine to be subject to different drive controls according to the operating position of a selection knob, though a controller may be continuously depressed in the same manner.
  • the sewing machine of this invention has a device for controlling the drive of the arm shaft in many ways, whereby, when the controller is depressed with the selection knob set at the first operating position, the arm shaft of the sewing machine is driven at a speed corresponding to the manner in which the controller is depressed, so as to perform normal stitching; upon release of the controller from depression, the arm shaft makes several rotations at a slow speed to be brought to rest at a predetermined angular position; when the controller is depressed with the selection knob set at the second operating position, the arm shaft makes just one rotation to be brought to rest at a predetermined angu lar position, regardless of the succession of the depression of the controller, so as to form a single stitch, thereby enabling basting to be carried out utilizing said single stitch forming operation; and when the controller is depressed with the selection knob set at the third operating position, the arm shaft is not driven at all, though the controller may be continued to be depressed, but brought to rest at a predetermined angular position, thereby permitting the bobbin winding utilizing the
