  REPORT 
  OF 
  COMMISSIONER 
  OF 
  FISH 
  AND 
  FISHERIES. 
  [98] 
  

  

  J, 
  to 
  force 
  the 
  fish 
  down 
  into 
  the 
  compression 
  cylinder 
  below, 
  alter 
  the 
  

   fish 
  has 
  been 
  placed 
  beneath 
  the 
  plunger 
  by 
  a 
  reciprocating 
  carrier, 
  K, 
  

   which 
  moves 
  in 
  a 
  trough, 
  L, 
  and 
  is 
  operated 
  by 
  a 
  peculiarly-shaped 
  

   lever-arm, 
  M, 
  notched 
  or 
  forked 
  at 
  M', 
  so 
  as 
  to 
  be 
  driven 
  from 
  the 
  ver- 
  

   tically-reciprocating 
  bar 
  N". 
  A 
  horizontal 
  lever, 
  O, 
  actuated 
  by 
  a 
  spring, 
  

   P, 
  and 
  a 
  cam, 
  Q, 
  on 
  the 
  end 
  of 
  the 
  shaft 
  A, 
  moves 
  the 
  bar 
  N 
  up 
  

   and 
  down. 
  The 
  upper 
  end 
  of 
  this 
  bar 
  has 
  a 
  rack, 
  E, 
  formed 
  upon 
  

   it, 
  which 
  engages 
  with 
  teeth 
  S, 
  circularly 
  placed 
  upon 
  one 
  side 
  of 
  a 
  

   hinged 
  swinging 
  plate, 
  T, 
  and 
  by 
  the 
  vertical 
  reciprocation 
  of 
  this 
  rack 
  

   the 
  plate 
  T 
  is 
  caused 
  to 
  swing 
  up 
  to 
  admit 
  the 
  forward 
  movement 
  of 
  

   the 
  carrier 
  K, 
  with 
  the 
  fish 
  which 
  has 
  been 
  placed 
  before 
  it, 
  and 
  after 
  

   the 
  carrier 
  has 
  been 
  withdrawn 
  it 
  swings 
  down, 
  so 
  as 
  to 
  complete 
  the 
  

   movement 
  of 
  forcing 
  the 
  fish 
  into 
  the 
  chute, 
  and 
  also 
  to 
  form 
  a 
  wall 
  at 
  

   that 
  side 
  while 
  the 
  plunger 
  passes 
  down. 
  The 
  compression-cylinder 
  

   into 
  which 
  the 
  fish 
  is 
  forced 
  by 
  the 
  plunger 
  1 
  is 
  placed 
  at 
  the 
  bottom 
  of 
  

   the 
  chute, 
  similarly 
  to 
  the 
  one 
  shown 
  in 
  the 
  patent 
  referred 
  to,- 
  but 
  the 
  

   knife 
  V, 
  by 
  which 
  the 
  fish 
  is 
  cut 
  and 
  shaped, 
  is 
  a 
  single 
  one, 
  working 
  

   entirely 
  in 
  one 
  direction. 
  This 
  knife 
  is 
  in 
  the 
  form 
  of 
  a 
  cylinder, 
  hav- 
  

   ing 
  an 
  opening 
  cut 
  out 
  of 
  oue 
  side 
  equal 
  in 
  its 
  dimensions 
  to 
  the 
  size 
  of 
  

   the 
  chute 
  through 
  which 
  the 
  fish 
  is 
  forced 
  down, 
  and 
  as 
  this 
  cylindri- 
  

   cal 
  knife 
  has 
  its 
  open 
  side 
  uppermost 
  when 
  the 
  plunger 
  I 
  is 
  forcing 
  the 
  

   fish 
  down 
  it 
  receives 
  enough 
  to 
  fill 
  it. 
  The 
  knife 
  then 
  rotates 
  upon 
  its 
  

   axis 
  sufficiently 
  to 
  cut 
  off 
  the 
  cylinder 
  full 
  and 
  at 
  the 
  same 
  time 
  close 
  it 
  

   off 
  from 
  the 
  chute. 
  A 
  horizontal 
  knife, 
  2, 
  is 
  so 
  placed 
  that 
  its 
  edge 
  is 
  

   opposite 
  to 
  and 
  assists 
  the 
  cylindrical 
  knife. 
  This 
  knife 
  V 
  has 
  a 
  flange, 
  

   W, 
  upon 
  one 
  end, 
  the 
  flange 
  having 
  notches 
  X 
  X 
  upon 
  opposite 
  sides 
  of 
  

   its 
  periphery, 
  as 
  shown, 
  and 
  these 
  notches 
  are 
  engaged 
  successively 
  by 
  

   the 
  point 
  y 
  of 
  a 
  curved 
  cam-shaped 
  lever, 
  Z, 
  which 
  is 
  pivoted 
  to 
  a 
  disk, 
  

   i, 
  on 
  the 
  side 
  of 
  the 
  eccentric-gear 
  wheel 
  a 
  and 
  rotates 
  with 
  it. 
  A 
  

   spring, 
  b, 
  holds 
  the 
  point 
  y 
  in 
  contact 
  with 
  the 
  periphery 
  of 
  the 
  flange 
  

   W, 
  and 
  when, 
  in 
  the 
  rotation 
  of 
  the 
  gear-wheel, 
  it 
  reaches 
  one 
  of 
  the 
  

   notches 
  X 
  it 
  will 
  fall 
  into 
  it 
  and 
  carry 
  the 
  knife 
  along 
  until 
  the 
  point 
  y 
  

   is 
  lifted 
  out 
  of 
  the 
  notch 
  by 
  the 
  action 
  of 
  a 
  stationary 
  pin, 
  c, 
  on 
  the 
  back 
  

   of 
  the 
  cam-lever 
  Z, 
  the 
  pin 
  being 
  fixed 
  to 
  the 
  outside 
  of 
  the 
  chute. 
  When 
  

   this 
  occurs 
  the 
  knife 
  remains 
  stationary 
  until 
  the 
  point 
  y 
  engages 
  the 
  next 
  

   notch 
  X 
  and 
  again 
  moves 
  the 
  knife. 
  By 
  this 
  action 
  the 
  knife 
  is 
  left 
  

   stationary 
  when 
  its 
  open 
  side 
  is 
  uppermost 
  and 
  in 
  line 
  with 
  the 
  chute, 
  

   so 
  as 
  to 
  receive 
  the 
  fish, 
  and 
  again 
  when 
  in 
  the 
  opposite 
  position 
  and 
  

   while 
  the 
  fish 
  is 
  being 
  forced 
  out 
  of 
  the 
  compression 
  and 
  forming 
  cylin- 
  

   der 
  into 
  the 
  can. 
  The 
  knife 
  is 
  driven 
  at 
  a 
  varying 
  rate 
  of 
  speed 
  by 
  

   means 
  of 
  the 
  two 
  eccentric 
  gears 
  a 
  a', 
  one 
  of 
  which 
  carries 
  the 
  actuat- 
  

   ing 
  cam-lever, 
  as 
  before 
  described, 
  while 
  the 
  other, 
  a', 
  which 
  is 
  the 
  

   driver, 
  is 
  mounted 
  upon 
  a 
  shaft, 
  this 
  shaft 
  carrying 
  a 
  bevel-piniou, 
  d, 
  

   and 
  the 
  bevel-gear 
  wheel 
  e 
  upon 
  the 
  main 
  shaft 
  A 
  meshes 
  with 
  and 
  

   drives 
  it. 
  The 
  disk 
  i 
  upon 
  the 
  side 
  of 
  the 
  eccentric 
  gear 
  a 
  is 
  held 
  and 
  

   adjusted 
  so 
  as 
  to 
  regulate 
  the 
  movements 
  of 
  the 
  knife 
  by 
  means 
  of 
  ;i
