  A 
  shaft 
  of 
  brass, 
  of 
  malleable 
  iron, 
  or 
  of 
  rubber, 
  has 
  a 
  recess 
  formed 
  

   by 
  overlapping 
  flanges 
  riveted 
  to 
  the 
  shaft, 
  and 
  of 
  such 
  width 
  as 
  to 
  

   cover 
  the 
  point 
  of 
  a 
  hook 
  and 
  prevent 
  its 
  reinsertion 
  in 
  drawing. 
  

  

  To 
  extract 
  a 
  hook 
  from 
  a 
  fish's 
  throat 
  the 
  line 
  is 
  drawn 
  moderately 
  

   taut 
  and 
  the 
  instrument 
  is 
  inserted 
  into 
  the 
  shank 
  of 
  the 
  hook, 
  em- 
  

   bracing 
  it 
  within 
  the 
  recess, 
  and 
  is 
  then 
  pushed 
  down 
  upon 
  the 
  inside 
  

   of 
  the 
  bend 
  of 
  the 
  hook 
  till 
  the 
  barb 
  is 
  liberated. 
  This 
  done, 
  the 
  ex- 
  

   tractor 
  is 
  withdrawn, 
  bringing 
  the 
  hook 
  with 
  it.

  (Louis 
  A. 
  Amouroux, 
  New 
  York, 
  N. 
  Y. 
  ; 
  patented 
  March 
  25, 
  1884 
  ; 
  machine 
  for 
  opening 
  

  

  oysters. 
  See 
  Plate 
  V. 
  ) 
  

  

  The 
  object 
  is 
  to 
  open 
  oysters 
  quickly 
  and 
  conveniently. 
  The 
  shell 
  is 
  

   separated 
  at 
  the 
  hinge 
  to 
  avoid 
  losing 
  the 
  juice. 
  

  

  A 
  frame 
  has 
  standards 
  for 
  supporting 
  a 
  fulcrumed 
  lever 
  having 
  a 
  ser- 
  

   rated 
  jaw, 
  against 
  which 
  the 
  oyster 
  is 
  placed, 
  and 
  an 
  adjustable 
  stand- 
  

   ard 
  is 
  rigidly 
  locked 
  to 
  the 
  slotted 
  base 
  of 
  the 
  frame, 
  and 
  provided 
  at 
  

   its 
  upper 
  end 
  with 
  a 
  twisted 
  and 
  pointed 
  knife 
  for 
  severing 
  the 
  butt 
  or 
  

   hinged 
  part 
  of 
  the 
  shell. 
  In 
  operation, 
  the 
  hook 
  d 
  of 
  the 
  detachable 
  

   upright 
  standard 
  D 
  is 
  first 
  so 
  placed 
  over 
  any 
  one 
  of 
  the 
  transverse 
  rods 
  

   « 
  2 
  , 
  as 
  to 
  be 
  at 
  a 
  desirable 
  distance 
  from 
  the 
  serrated 
  lever 
  B, 
  according 
  

   to 
  the 
  size 
  of 
  the 
  oyster 
  to 
  be 
  opened. 
  The 
  oyster 
  is 
  then 
  placed 
  with 
  

   its 
  mouth 
  against 
  one 
  of 
  the 
  teeth 
  of 
  the 
  jaw, 
  while 
  the 
  butt 
  or 
  hinged 
  

   end 
  of 
  the 
  shell 
  is 
  placed 
  against 
  the 
  knife. 
  The 
  lever 
  is 
  then 
  pressed 
  

   down, 
  and 
  the 
  butt 
  of 
  the 
  oyster 
  forced 
  against 
  the 
  knife, 
  whereby 
  the 
  

   muscle 
  that 
  holds 
  together 
  the 
  two 
  halves 
  of 
  the 
  shell 
  is 
  severed 
  by 
  the 
  

   point 
  of 
  the 
  knife, 
  while 
  the 
  sections 
  of 
  the 
  shell 
  are 
  separated 
  by 
  the 
  

   twisted 
  portion. 
  The 
  shell 
  is 
  then 
  opened 
  by 
  a 
  recessed 
  knife, 
  by 
  which 
  

   also 
  the 
  oyster 
  is 
  removed. 
  

  

  The 
  inventor 
  says 
  : 
  

  

  " 
  I 
  am 
  aware 
  that 
  oyster-openers 
  in 
  which 
  a 
  fixed 
  serrated 
  abutment 
  

   and 
  a 
  reciprocating 
  knife 
  are 
  employed 
  have 
  been 
  used 
  heretofore, 
  and 
  

   I 
  do 
  not 
  claim 
  the 
  same."
