Definitions

  • a reciprocatory needle cooperating with said needle in the formatio of lock-stitches, a thread-case journaled in said rotary hook, means for confining the thread-case to limited oscillation, an opener-finger adapted to engage the thread-case to oscillate it in one direction, a pivotal rocker carrying said openerfinger, a reciprocatory pitman, a cushioned swivel-connection between said rocker and the pitman, and means for reciprocating said pitman,
  • a needle means for reciprocating said needle, a hook performing a plurality of rotations for each needle reciprocatiom'a thread-case journaled in said hook, means for restraining the thread-case against rotation with said hook, an opener-finger adapted to turn the thread case in a direction opposite to the direction of rotation of the book, a rocker carrying said finger, a pivotal support for said rocker upon opposite sides of the hook, a reciprocatory pitman, a universal-joint connection between said pitman and the rocker, and means for reciprocating said pitman once for each needle reciprocation.
