  lessened. 
  This 
  is 
  especially 
  true 
  when 
  the 
  fish 
  have 
  become 
  decom- 
  

   posed. 
  It 
  has 
  been 
  claimed 
  that 
  the 
  use 
  of 
  the 
  curbs 
  yields 
  fully 
  10 
  

   tons 
  more 
  of 
  scrap 
  from 
  a 
  million 
  of 
  fish 
  than 
  the 
  screw 
  presses. 
  The 
  

   mass 
  of 
  fish 
  drops 
  from 
  the 
  cooker 
  to 
  a 
  screw 
  conveyor, 
  which 
  feeds 
  

   it 
  to 
  a 
  bucket 
  conveyor 
  to 
  be 
  carried 
  to 
  the 
  second 
  floor, 
  where 
  it 
  

   passes 
  to 
  a 
  second 
  screw 
  conveyor 
  extending 
  tlirough 
  the 
  center 
  of 
  

   the 
  room 
  over 
  the 
  draining 
  tanks; 
  the 
  box 
  containing 
  this 
  conveyor 
  

   is 
  provided 
  with 
  troughs 
  through 
  which 
  the 
  mass 
  drops 
  to 
  the 
  tanks, 
  

   where 
  it 
  remains 
  over 
  night, 
  during 
  which 
  time 
  a 
  considerable 
  quan- 
  

   tity 
  of 
  the 
  oil 
  and 
  water 
  drains 
  off 
  and 
  is 
  carried 
  through 
  troughs 
  to 
  

   the 
  oil 
  tanks. 
  

  

  In 
  the 
  morning 
  the 
  men 
  get 
  into 
  the 
  draining 
  tanks 
  and 
  throw 
  the 
  

   cooked 
  mass 
  over 
  into 
  the 
  curbs, 
  using 
  a 
  large 
  fork, 
  the 
  tines 
  of 
  which 
  

   are 
  close 
  enough 
  to 
  retain 
  the 
  solid 
  matter 
  and 
  yet 
  permit 
  a 
  portion 
  

   of 
  the 
  oil 
  and 
  water 
  to 
  run 
  through. 
  The 
  most 
  common 
  form 
  of 
  curb 
  

   now 
  in 
  use 
  is 
  a 
  cylindrical 
  tub 
  provided 
  with 
  four 
  wheels, 
  about 
  20 
  

   inches 
  in 
  diameter, 
  so 
  as 
  to 
  run 
  on 
  a 
  tramway 
  which 
  is 
  built 
  alongside 
  

   the 
  draining 
  tanks; 
  the 
  tub 
  is 
  40 
  inches 
  deep, 
  35 
  inches 
  diameter 
  at 
  

   the 
  top, 
  and 
  slightly 
  wider 
  at 
  the 
  bottom; 
  it 
  is 
  constructed 
  of 
  100 
  

   beveled 
  iron 
  staves, 
  three-eighths 
  inch 
  thick, 
  seven-eighths 
  inch 
  

   wide 
  on 
  the 
  outer 
  side, 
  and 
  slightly 
  wider 
  on 
  the 
  inner 
  side, 
  with 
  

   sufficient 
  space 
  left 
  between 
  the 
  staves 
  to 
  permit 
  the 
  escape 
  of 
  the 
  

   oil 
  and 
  water. 
  The 
  staves 
  are 
  securely 
  riveted 
  to 
  heavy 
  iron 
  bands 
  

   which 
  encircle 
  them, 
  and 
  every 
  tenth 
  stave 
  widens 
  from 
  the 
  center 
  

   toward 
  the 
  lower 
  end, 
  thus 
  giving 
  the 
  curb 
  an 
  increased 
  width 
  at 
  the 
  

   bottom 
  so 
  that 
  the 
  hard 
  cake 
  remaining 
  after 
  the 
  pressure 
  is 
  relaxed 
  

   can 
  be 
  more 
  easily 
  expelled. 
  A 
  hollow 
  core, 
  about 
  12 
  inches 
  in 
  

   diameter 
  and 
  33 
  inches 
  long, 
  fits 
  in 
  the 
  center 
  of 
  the 
  curb; 
  this 
  is 
  made 
  

   of 
  staves 
  similar 
  to 
  those 
  already 
  described 
  and 
  has 
  a 
  rounded 
  top 
  

   of 
  iron 
  in 
  the 
  center 
  of 
  which 
  is 
  an 
  eyebolt; 
  a 
  hook 
  which 
  may 
  be 
  

   attached 
  to 
  a 
  chain 
  working 
  in 
  a 
  pulley 
  suspended 
  from 
  above, 
  or 
  to 
  

   a 
  piece 
  of 
  wood 
  which 
  is 
  laid 
  across 
  the 
  top 
  of 
  the 
  curb, 
  is 
  caught 
  in 
  

   this 
  eyebolt 
  when 
  the 
  pressed 
  mass 
  is 
  released, 
  to 
  prevent 
  the 
  core 
  

   dropping. 
  The 
  bottom 
  of 
  the 
  curb 
  is 
  simply 
  a 
  piece 
  of 
  heavy 
  sheet 
  

   iron 
  attached 
  to 
  the 
  lower 
  band 
  of 
  the 
  curb 
  by 
  means 
  of 
  a 
  loose-pin 
  

   hinge; 
  the 
  opposite 
  side 
  of 
  the 
  bottom 
  is 
  held 
  in 
  place 
  by 
  a 
  lathe 
  

   which 
  is 
  opened 
  by 
  a 
  lever 
  when 
  the 
  curb 
  is 
  to 
  be 
  emptied, 
  permitting 
  

   the 
  bottom 
  to 
  swing. 
  The 
  curb 
  is 
  attached, 
  by 
  means 
  of 
  stays 
  on 
  

   one 
  of 
  the 
  iron 
  bands 
  referred 
  to 
  above, 
  to 
  a 
  square 
  frame 
  of 
  ^ 
  inch 
  

   by 
  2 
  J 
  inch 
  iron, 
  which 
  is 
  built 
  about 
  it; 
  this 
  frame 
  also 
  serves 
  as 
  the 
  

   axles, 
  and 
  the 
  spindles 
  on 
  which 
  the 
  wheels 
  revolve 
  are 
  bolted 
  to 
  it 
  

   at 
  the 
  corners. 
  

  

  When 
  the 
  curb 
  is 
  filled 
  it 
  is 
  run 
  on 
  the 
  railway 
  to 
  a 
  point 
  under 
  a 
  

   stationary 
  head 
  which 
  fits 
  closely 
  inside 
  the 
  curb; 
  as 
  the 
  latter 
  is 
  

   slowly 
  raised 
  by 
  a 
  powerful 
  hydraulic 
  press 
  the 
  fish 
  are 
  pressed
