Abstract
A bobbin and gripper assembly for a double-lock-stitch sewing machine has a stitch plate lying in a horizontal plane and a gripper rotatable in a horizontal plane below the stitch plate and receiving a bobbin housing. The latter is provided with a retaining finger which cooperates with abutments formed on the underside of the stitch plate to retain the bobbin housing against rotation with the gripper. In addition, the bobbin housing is held by a spring member which is effective to yieldably retard the bobbin against rotation in the direction of rotation of the gripper by friction therewith.
