  — 
  Improved 
  Rook 
  Cutter 
  and 
  Trimmer. 
  

  

  Two 
  forms 
  of 
  cutter 
  were 
  made, 
  and 
  a 
  duplicate 
  set 
  of 
  each 
  

   was 
  provided. 
  The 
  working 
  drawings, 
  tig. 
  2, 
  show 
  the 
  details 
  

   of 
  cutters 
  so 
  clearly 
  that 
  further 
  description 
  is 
  unnecessary. 
  

   The 
  specification 
  required 
  that 
  these 
  cutters 
  should 
  be 
  of 
  the 
  

  

  best 
  quality 
  Jessop's, 
  Stubb's, 
  or 
  Mushet's 
  steel, 
  tempered 
  very 
  

   hard. 
  It 
  might 
  be 
  better 
  for 
  some 
  kinds 
  of 
  work 
  to 
  have 
  

   another 
  form 
  of 
  cutter, 
  with 
  edges 
  at 
  an 
  angle" 
  of 
  45° 
  with 
  top 
  

   edge 
  of 
  jaws, 
  but 
  the 
  two 
  forms 
  already 
  mentioned 
  have 
  so 
  far 
  

   answered 
  all 
  requirements.

  Cutters

   There 
  should 
  be 
  also 
  two 
  pins, 
  \" 
  diameter,

  for 
  holding 
  cutters

  Unless 
  a 
  large 
  amount 
  of 
  work 
  is 
  to 
  be 
  done, 
  it 
  will 
  be 
  

   advisable 
  to 
  order 
  only 
  a 
  single 
  set 
  of 
  cutters. 
  This 
  will 
  make 
  

   a 
  material 
  reduction 
  in 
  the 
  first 
  cost 
  of 
  the 
  machine, 
  and 
  one 
  

   set 
  of 
  cutters, 
  if 
  properly 
  cared 
  for, 
  will 
  last 
  for 
  ye 
  ars.
