  screw, 
  /, 
  which 
  passes 
  through 
  slots 
  in 
  the 
  gear 
  a, 
  so 
  that 
  it 
  may 
  be 
  

   moved 
  around 
  the 
  axis, 
  and 
  thus 
  change 
  the 
  position 
  of 
  the 
  cam-lever 
  

   Z 
  relative 
  to 
  the 
  flange 
  W. 
  The 
  knife 
  is 
  moved 
  slowly 
  when 
  its 
  open 
  

   side 
  and 
  cutting-edge 
  arc 
  downward, 
  and 
  it 
  is 
  moved 
  at 
  its 
  greatest 
  

   speed 
  when 
  the 
  open 
  side 
  is 
  upward 
  and 
  the 
  inclined 
  cutting-edge 
  is 
  

   moving 
  across 
  the 
  chute 
  to 
  cut 
  off 
  the 
  supply. 
  The 
  piston 
  g 
  moves 
  

   through 
  the 
  center 
  of 
  the 
  cylindrical 
  knife 
  and 
  forces 
  the 
  fish 
  from 
  it 
  

   into 
  the 
  extension 
  h, 
  upon 
  which 
  the 
  can 
  fits, 
  as 
  described 
  in 
  the 
  former 
  

   patent 
  above 
  referred 
  to. 
  The 
  movement 
  of 
  this 
  piston 
  is 
  effected 
  by 
  

   means 
  of 
  a 
  pin, 
  i, 
  projecting 
  from 
  the 
  disk 
  j 
  on 
  the 
  end 
  of 
  the 
  shaft 
  A, 
  

   this 
  pin 
  striking 
  an 
  arm, 
  7c, 
  which 
  projects 
  downward 
  from 
  the 
  guide 
  

   extending 
  in 
  rear 
  of 
  the 
  pistons. 
  A 
  bent 
  arm, 
  I, 
  pivoted 
  to 
  the 
  frame 
  

   below, 
  has 
  a 
  pin 
  projecting 
  in 
  front 
  of 
  the 
  arm 
  fc, 
  and 
  the 
  arm 
  I 
  is 
  acted 
  

   upon 
  by 
  the 
  pin 
  upon 
  the 
  disk, 
  so 
  as 
  to 
  return 
  the 
  piston 
  after 
  it 
  has 
  

   been 
  forced 
  forward, 
  in 
  the 
  same 
  manner 
  as 
  shown 
  in 
  former 
  patent. 
  

   A 
  vertically-sliding 
  knife 
  or 
  plate, 
  m, 
  is 
  formed 
  across 
  the 
  space 
  between 
  

   the 
  cylindrical 
  forming-knife 
  and 
  the 
  rear 
  part 
  of 
  the 
  extension 
  h 
  upon 
  

   which 
  the 
  can 
  fits, 
  as 
  soon 
  as 
  the 
  piston 
  has 
  been 
  withdrawn 
  past 
  that 
  

   point, 
  and 
  thus 
  closes 
  the 
  end 
  of 
  the 
  cylindrical 
  knife 
  and 
  former 
  for 
  

   the 
  introduction 
  of 
  another 
  charge 
  by 
  the 
  plunger 
  moving 
  in 
  the 
  chute. 
  

   The 
  sliding 
  knife 
  m 
  has 
  a 
  stem 
  projecting 
  downward, 
  and 
  a 
  spiral 
  or 
  

   other 
  spring, 
  n, 
  acts 
  against 
  a 
  pin 
  or 
  shoulder 
  to 
  return 
  the 
  knife 
  after 
  

   it 
  has 
  been 
  drawn 
  down 
  and 
  then 
  released. 
  The 
  knife 
  is 
  drawn 
  down 
  

   out 
  of 
  the 
  cylinder 
  by 
  means 
  of 
  an 
  arm, 
  o, 
  one 
  end 
  of 
  which 
  is 
  connected 
  

   with 
  the 
  stem 
  of 
  the 
  knife, 
  while 
  the 
  opposite 
  end 
  is 
  curved 
  and 
  brought 
  

   into 
  such 
  a 
  position 
  relative 
  to 
  a 
  cam, 
  p, 
  upon 
  the 
  main 
  shaft 
  that 
  as 
  

   the 
  shaft 
  rotates 
  the 
  cam 
  acts 
  upon 
  the 
  lever, 
  moving 
  it 
  about 
  its 
  ful- 
  

   crum 
  until 
  the 
  knife 
  is 
  drawn 
  down, 
  and 
  then 
  releases 
  it, 
  so 
  that 
  the 
  

   spring 
  throws 
  it 
  back 
  again. 
  When 
  the 
  supply 
  of 
  fish 
  within 
  the 
  ver- 
  

   tical 
  chute 
  is 
  sufficient 
  the 
  swinging 
  gate 
  T 
  is 
  prevented 
  from 
  opening 
  

   by 
  a 
  latch, 
  r, 
  a 
  notch 
  in 
  which 
  engages 
  one 
  of 
  the 
  pins 
  or 
  teeth 
  S 
  (by 
  

   which 
  and 
  the 
  rack 
  R 
  it 
  is 
  operated), 
  and 
  thus 
  holds 
  it 
  against 
  the 
  

   action 
  of 
  the 
  spring 
  ? 
  until 
  the 
  latch 
  is 
  tripped 
  and 
  the 
  gear 
  released. 
  

   As 
  long 
  as 
  the 
  chute 
  contains 
  a 
  quantity 
  of 
  fish 
  the 
  plunger 
  I 
  will 
  not 
  

   descend 
  very 
  low; 
  but 
  as 
  soon 
  as 
  the 
  quantity 
  diminishes 
  to 
  a 
  certain 
  

   point 
  an 
  arm, 
  t, 
  which 
  is 
  secured 
  to 
  the 
  upper 
  part 
  of 
  the 
  plunger 
  and 
  

   moves 
  with 
  it, 
  passing 
  down 
  outside 
  the 
  chute, 
  will 
  strike 
  the 
  rear 
  end 
  

   of 
  the 
  latch 
  r, 
  and 
  thus 
  disengage 
  it, 
  so 
  that 
  the 
  gate 
  can 
  operate. 
  The 
  

   cam 
  which 
  moves 
  the 
  lever 
  by 
  which 
  the 
  plunger 
  is 
  actuated 
  may 
  be 
  

   turned 
  upon 
  the 
  shaft, 
  so 
  as 
  to 
  regulate 
  the 
  movement 
  of 
  the 
  plunger, 
  

   by 
  means 
  of 
  a 
  screw, 
  E', 
  passing 
  through 
  a 
  slot 
  in 
  a 
  disk 
  upon 
  the 
  main 
  

   shaft, 
  the 
  cam 
  lying 
  in 
  contact 
  with 
  the 
  disk.
