  the 
  second 
  head 
  of 
  the 
  pair 
  upon 
  which 
  it 
  alternately 
  turns, 
  and 
  as 
  soon 
  

   as 
  it 
  is 
  thus 
  engaged 
  the 
  other 
  end 
  of 
  the 
  brocheur 
  will 
  be 
  disengaged 
  

   from 
  the 
  head 
  upon 
  which 
  it 
  has 
  made 
  a 
  quarter 
  of 
  a 
  revolution, 
  and 
  it 
  

   will 
  then 
  make 
  the 
  next 
  quarter 
  of 
  a 
  revolution 
  upon 
  the 
  second 
  head. 
  

   The 
  thread-bearer 
  and 
  the 
  brocheur-frame 
  then 
  separate, 
  the 
  latter 
  also 
  

   making 
  a 
  partial 
  turn 
  backward 
  about 
  its 
  axis, 
  whereby 
  the 
  hall-hitch 
  

   formed 
  by 
  the 
  weft-thread 
  around 
  the 
  loop 
  of 
  the 
  warp-thread 
  will 
  be 
  

   drawn 
  down 
  toward 
  the 
  first 
  part 
  of 
  the 
  knot 
  which 
  is 
  illustrated 
  in 
  

   Figs. 
  21 
  and 
  21 
  a 
  . 
  The 
  thread-leader 
  V 
  then 
  swings 
  back 
  to 
  its 
  first 
  

   position 
  near 
  the 
  feed-bar 
  roller, 
  and 
  the 
  brocheur-frame 
  and 
  thread- 
  

   holder 
  approach 
  each 
  other, 
  assuming 
  the 
  position 
  taken 
  in 
  forming 
  the 
  

   first 
  part 
  of 
  the 
  knot, 
  the 
  thread-holder 
  swinging 
  as 
  before 
  and 
  the 
  

   brocheur-frame 
  moving 
  toward 
  the 
  thread-holder 
  and 
  making 
  a 
  partial 
  

   rotation 
  about 
  its 
  axis, 
  to 
  bring 
  the 
  reels 
  underneath 
  and 
  in 
  a 
  vertical 
  

   position, 
  as 
  shown 
  in 
  Fig. 
  22. 
  The 
  thread-holder, 
  in 
  moving 
  toward 
  the 
  

   brocheur-frame, 
  makes 
  a 
  partial 
  rotation 
  about 
  its 
  axis, 
  so 
  that 
  it 
  will 
  

   slant 
  when 
  it 
  arrives 
  in 
  position 
  over 
  the 
  finger 
  of 
  the 
  brocheur-frame. 
  

   This 
  movement 
  on 
  the 
  part 
  of 
  the 
  thread-holder 
  is 
  caused 
  by 
  its 
  finger 
  I 
  2 
  

   striking 
  against 
  the 
  upper 
  end 
  of 
  the 
  vertical 
  slide-bar 
  I', 
  which 
  has 
  

   meanwhile 
  been 
  raised 
  for 
  such 
  purpose 
  by 
  the 
  cam 
  L 
  2 
  acting 
  upon 
  the 
  

   pin 
  I 
  on 
  said 
  bar 
  I', 
  already 
  described. 
  The 
  slant 
  of 
  the 
  thread-bearer 
  

   opens 
  the 
  loop 
  in 
  the 
  warp-thread, 
  as 
  shown 
  in 
  Fig. 
  22, 
  such 
  action 
  be- 
  

   ing 
  effected 
  by 
  means 
  of 
  a 
  pair 
  of 
  the 
  pins 
  that 
  close 
  the 
  slot 
  in 
  the 
  

   thread 
  -bearer, 
  it 
  being 
  seen 
  that 
  the 
  second 
  part 
  of 
  the 
  warp-thread 
  will 
  

   be 
  thrown 
  away 
  from 
  the 
  first 
  part 
  by 
  the 
  pin 
  nearest 
  the 
  outer 
  end 
  of 
  

   the 
  slot. 
  The 
  brocheur 
  is 
  then 
  caused 
  to 
  return 
  or 
  make 
  a 
  half-turn 
  in 
  

   the 
  same 
  manner, 
  but 
  in 
  a 
  reverse 
  direction 
  to 
  that 
  which 
  it 
  has 
  made 
  

   in 
  forming 
  the 
  first 
  part 
  of 
  the 
  knot, 
  the 
  secoud 
  star-wheel 
  coining 
  into 
  

   play 
  in 
  this 
  instance 
  for 
  the 
  purpose 
  of 
  actuating 
  the 
  rack-bars 
  that 
  

   cause 
  a 
  simultaneous 
  movement 
  of 
  the 
  pinions 
  carried 
  by 
  the 
  brocheur- 
  

   frame. 
  In 
  this 
  movement 
  of 
  the 
  brocheur 
  the 
  reel, 
  with 
  the 
  weft-thread, 
  

   is 
  carried 
  through 
  the 
  loop 
  formed 
  of 
  warp-thread, 
  and 
  this 
  forms 
  the 
  

   second 
  part 
  of 
  the 
  knot, 
  as 
  shown 
  in 
  Figs. 
  23 
  and 
  23 
  a 
  , 
  which, 
  when 
  

   tightened 
  up, 
  will 
  not 
  slip 
  under 
  any 
  circumstances. 
  The 
  brocheur- 
  

   frame 
  then 
  moves 
  back, 
  and, 
  making 
  a 
  partial 
  revolution 
  about 
  its 
  

   axis, 
  returns 
  to 
  its 
  first 
  position 
  ; 
  that 
  is 
  to 
  say, 
  the 
  one 
  which 
  it 
  occu- 
  

   pied 
  preparatory 
  to 
  tying 
  the 
  first 
  part 
  of 
  the 
  knot, 
  as 
  shown 
  in 
  Fig. 
  

   19. 
  The 
  thread-holder 
  swings 
  away 
  from 
  the 
  brocheur-frame 
  and 
  drops 
  

   the 
  warp-threads, 
  the 
  arm 
  C 
  8 
  striking 
  one 
  end 
  of 
  the 
  inner 
  section 
  of 
  

   the 
  thread-holder 
  to 
  effect 
  such 
  release 
  of 
  the 
  threads. 
  The 
  feed-roller 
  

   bar 
  also 
  moves 
  back, 
  thereby 
  drawing 
  th 
  a 
  warp-threads 
  and 
  tightening 
  

   up 
  the 
  knot. 
  The 
  knots 
  being 
  tied 
  upon 
  the 
  fingers 
  of 
  the 
  mold-bar 
  

   and 
  the 
  mesh 
  formed 
  around 
  them, 
  the 
  highest 
  mold-bar 
  upon 
  which 
  

   the 
  meshes 
  have 
  been 
  formed 
  drops, 
  and 
  is 
  also 
  shifted 
  back 
  a 
  sufficient 
  

   distance 
  to 
  cause 
  its 
  fingers 
  to 
  slip 
  out 
  from 
  the 
  meshes 
  formed 
  and 
  al- 
  

   low 
  the 
  same 
  to 
  be 
  taken 
  between 
  the 
  rollers, 
  as 
  shown 
  in 
  Fig. 
  24.
