  which 
  the 
  catch 
  -hook 
  is 
  held 
  by 
  means 
  of 
  a 
  clamp. 
  In 
  using 
  this 
  class 
  

   of 
  hooks 
  it 
  is 
  desirable 
  to 
  be 
  able 
  to 
  set 
  the 
  catch-hook 
  so 
  that 
  it 
  will 
  

   be 
  released 
  and 
  strike 
  the 
  fish 
  biting 
  on 
  the 
  bait-hook, 
  while 
  it 
  is 
  at 
  the 
  

   same 
  time 
  desirable 
  to 
  have 
  the 
  catch-hook 
  set 
  in 
  such 
  a 
  manner 
  that 
  

   it 
  will 
  not 
  strike 
  the 
  fish 
  which 
  may 
  only 
  be 
  nibbling 
  at 
  the 
  bait. 
  To 
  

   this 
  end 
  the 
  clamp 
  is 
  made 
  adjustable 
  on 
  the 
  shank, 
  so 
  that 
  it 
  may 
  

   clamp 
  the 
  catch-hook 
  farther 
  from 
  or 
  closer 
  to 
  the 
  fulcrum 
  of 
  the 
  latter, 
  

   according 
  to 
  the 
  nature 
  and 
  manner 
  of 
  biting 
  of 
  the 
  fish 
  for 
  which 
  the 
  

   bait 
  is 
  set, 
  more 
  force 
  being 
  required 
  to 
  release 
  the 
  catch-hook 
  when 
  it 
  

   is 
  clamped 
  far 
  from 
  the 
  fulcrum 
  thamwhen 
  it 
  is 
  clamped 
  near 
  to 
  it. 
  The 
  

   spring-catch 
  F 
  consists 
  of 
  a 
  strip 
  of 
  spring 
  metal 
  forming 
  an 
  eye, 
  F', 
  

   at 
  its 
  inner 
  doubled 
  end, 
  which 
  slides 
  upon 
  rod 
  D. 
  The 
  ends 
  are 
  held 
  

   together 
  by 
  a 
  small 
  set-screw, 
  G, 
  while 
  its 
  outer 
  ends 
  form 
  wings 
  /, 
  

   which 
  clasp 
  the 
  shank 
  of 
  the 
  hook 
  C, 
  when 
  inserted, 
  in 
  such 
  a 
  manner 
  

   that 
  by 
  a 
  slight 
  pull 
  it 
  may 
  be 
  drawn 
  out 
  of 
  the 
  said 
  clamp. 
  As 
  the 
  

   fish 
  takes 
  the. 
  bail 
  and 
  pulls 
  upon 
  the 
  bait-hook 
  A, 
  this 
  in 
  turn 
  pulling 
  

   upon 
  the 
  enlargement 
  B 
  of 
  the 
  upper 
  hook, 
  0, 
  will 
  tilt 
  this 
  upon 
  its 
  

   fulcrum 
  in 
  the 
  eye 
  d, 
  so 
  as 
  to 
  release 
  it 
  from 
  the 
  spring-clamp 
  F 
  on 
  rod 
  

   D, 
  thereby, 
  by 
  the 
  leverage 
  between 
  the 
  points 
  b 
  and 
  d, 
  throwing 
  the 
  

   upper 
  hook 
  downward 
  with 
  considerable 
  force, 
  causing 
  its 
  barbed 
  point 
  

   to 
  penetrate 
  the 
  body 
  of 
  the 
  fish 
  caught 
  on 
  the 
  bait-hook, 
  so 
  that 
  it 
  

   will 
  be 
  impossible 
  for 
  the 
  catch 
  to 
  escape. 
  

  

  CLAIM. 
  

  

  "The 
  combination, 
  in 
  a 
  fish-hook 
  of 
  the 
  described 
  class, 
  of 
  the 
  spring- 
  

   clamp 
  F, 
  forming 
  eye 
  F', 
  and 
  clamping-wings 
  /, 
  having 
  set-screws 
  U 
  

   and 
  sliding 
  adjustably 
  upon 
  rod 
  D, 
  with 
  the 
  catch-hook 
  hinged 
  to 
  

   the 
  end 
  of 
  rod 
  D, 
  and 
  having 
  bait-hook 
  A 
  hinged 
  near 
  its 
  fulcrum, 
  as 
  

   and 
  for 
  the 
  purpose 
  shown 
  and 
  set 
  forth."
