  • Bobbin winding actuation by buttonhole selection
    Patent number: 4503793
    Abstract: A method for implementing winding of a lower thread bobbin in place in a looptaker of a sewing machine from an upper thread supply. A buttonhole pattern in which at least one initial stitch is effected at one end of the buttonhole prior to holding needle bar reciprocation in abeyance while feeding the work material to the other end of the buttonhole, is selected but is utilized without a traveling buttonhole foot which would reinitiate stitching and feeding of the work material. Instead, any other presser foot, or no presser foot, is used so that bobbin winding may proceed after upper thread is initially brought to the lower bobbin, without having thread flow interferred with by needle bar reciprocation.

  • Expanded interval timer drive mechanism
    Patent number: 4500212
    Abstract: An expanded interval drive mechanism for a program timer includes a lift cam which periodically engages a pawl lifter to move the pawl lifter so as to lift the drive pawl away from the ratchet teeth. The ratchet teeth are at two levels. Where the ratchet teeth are at the lower level, operation of the pawl lifter prevents the drive pawl from engagement with the lower level ratchet teeth. However, the higher level ratchet teeth are always engaged by the drive pawl regardless of the operation of the pawl lifter. Therefore, an expanded interval is achieved in the region having the lower level ratchet teeth.

  • Balanced armature winding for motors
    Patent number: 4495430
    Abstract: The back EMF generated in armature coils is substantially balanced by causing the coils located a greater distance from the axis of rotation of the armature to have fewer turns than the coils located closer to the armature axis of rotation. Alternatively, rather than decrease the number of turns in the coils, the same balancing affect can be achieved by increasing the electrical resistance of the coils located a greater distance from the armature axis of rotation.
