  • the above-described operation is based on the assumption that there is thread still remaining on the supply spool 15. if, when the feeler lever 21 moves as described above in the case of a thread break, there is a downward movement of feeler lever 18. This indicates that the supply spool is exhausted and that there is no thread between the supply spool 15 and thread tensioner 19. in this case, the downward movement of feeler 18 causes the bell crank lever 41 to turn about pivot 42 in a clockwise direction, as viewed in Fig. 1, and this causes the rod 44 to swing to the left, as viewed in Fig.
  • lever 113, 114 when the lever 113, 114 is actuated by cam 63, asdescribed above, the clockwise turning of lever portion 114 produces a downward movement of rod 44 and a clockwise turning of lever 30, 31, 32 about pivot 29.
