ABSTRACT:
A device for preventing the rotation of the bobbin case member of a horizontally fully rotatable shuttle comprises a retaining member adapted to contact one portion of the inner shuttle member for retaining the bobbin case member against rotation. One of the contact faces of the bobbin case member and the retaining member is partly formed with a recess. The retaining member is reciprocally movable along the contact face of the bobbin case member to prevent the rotation of the shuttle member and permit release of an upper thread free of resistance.
