  front 
  it 
  has 
  inward 
  

   inclined 
  or 
  deflected 
  rows 
  of 
  converging 
  staple-shaped 
  bars. 
  The 
  

   staple-shaped 
  bars 
  are 
  also 
  arranged 
  in 
  a 
  horizontal 
  position, 
  and

   at 
  their 
  looped 
  or 
  connected 
  ends, 
  while 
  their 
  other 
  portions 
  are 
  passed 
  

   through 
  a 
  second 
  upright

  the 
  cage,

  their 
  free 
  ends 
  extended 
  

   beyond 
  the 
  upright 
  to 
  a 
  point 
  a 
  short 
  distance 
  forward 
  and 
  at 
  one 
  side 
  

   of 
  a 
  vertical 
  plane 
  passing 
  centrally 
  through 
  the 
  cage. 
  The 
  opposite 
  

   row 
  of 
  staple-shaped 
  bars 
  is 
  similarly 
  arranged 
  and 
  secured 
  in 
  position, 
  

   whereby 
  a 
  chute, 
  having 
  a

  opening, 
  is 
  provided 
  to 
  

   direct 
  the 
  fish 
  into 
  the 
  cage 
  or 
  trap. 
  The 
  cage 
  is 
  suspended 
  and 
  verti- 
  

   cally 
  adjusted 
  or 
  raised 
  and 
  lowered 
  by 
  a 
  rope 
  or 
  chain, 
  passed 
  through 
  

   tackle 
  or 
  pulley 
  blocks 
  connected 
  to 
  a 
  cross-beam, 
  a 
  hook 
  and 
  ring, 
  

   and 
  to 
  the 
  top 
  crossing-bars 
  of 
  the 
  cage 
  or 
  trap 
  in 
  a 
  similar 
  manner. 
  

   The 
  beam 
  is 
  secured 
  at 
  one 
  end, 
  upon 
  an 
  upright, 
  fastened 
  to 
  the 
  boat 
  

   at 
  the 
  front 
  side 
  of 
  the 
  opening 
  therein, 
  and 
  upon 
  a 
  cross-bar 
  secured 
  

   to 
  uprights, 
  also 
  fastened 
  to 
  the 
  ponton 
  at 
  the 
  sides 
  of 
  the 
  opening 
  

   The 
  rope 
  or 
  chain 
  is 
  further 
  passed 
  over 
  a 
  pulley 
  supported 
  upon 
  the 
  

   upright, 
  thence 
  under 
  a 
  pulley 
  at 
  the 
  lower 
  end 
  of 
  the 
  upright, 
  and 
  

   finally 
  connected 
  to 
  a 
  winding 
  apparatus 
  upon 
  the 
  boat. 
  

  

  The 
  lead-net 
  B 
  is 
  hung 
  in 
  the 
  opening 
  in 
  the 
  boat, 
  with 
  its 
  upper 
  

   edges 
  connected 
  to 
  rods 
  secured 
  to 
  the 
  sides 
  of 
  the 
  opening, 
  while 
  its 
  

   bottom 
  may 
  be 
  made 
  of 
  slats, 
  G, 
  secured 
  in 
  a 
  bottom 
  frame 
  to 
  rods 
  to 
  

   which 
  it 
  is 
  attached 
  at 
  its 
  lower 
  side 
  edges. 
  The 
  bottom 
  of 
  the 
  net 
  is 
  

   connected 
  to 
  the 
  bottom 
  of 
  the 
  trap 
  at 
  one 
  end 
  by 
  eyebolts 
  and 
  hooks, 
  

   while 
  the 
  ends 
  of 
  the 
  sides 
  o± 
  the 
  net 
  are 
  connected 
  by 
  rings 
  to 
  bail- 
  

   shaped 
  rods 
  fastened 
  to 
  the 
  corner-posts 
  of 
  the 
  front 
  frame 
  of 
  the 
  trap 
  

   by 
  their 
  horizontal 
  portions. 
  The 
  lead-net 
  is 
  connected 
  near 
  its 
  outer 
  

   end 
  to 
  a 
  bail 
  to 
  which 
  is 
  attached 
  a, 
  rope, 
  passed 
  up 
  over 
  a 
  pulley, 
  hung 
  

   upon 
  a 
  beam, 
  secured 
  to 
  uprights, 
  fastened 
  to 
  the 
  sides 
  of 
  the 
  opening 
  

   in 
  the 
  boat 
  near 
  its 
  stern. 
  This 
  arrangement 
  permits 
  the 
  raising 
  and 
  

   lowering 
  of 
  the 
  lead-net 
  simultaneously 
  with 
  the 
  vertical 
  adjustment 
  of 
  

   the 
  trap 
  in 
  letting 
  the 
  same 
  down 
  into 
  the 
  water 
  to 
  entrap 
  or 
  impound 
  

   the 
  fish, 
  and 
  removing 
  the 
  same 
  from 
  the 
  water 
  to 
  enable 
  the 
  fish 
  to 
  be 
  

   taken 
  from 
  the 
  trap, 
  which 
  is 
  done 
  through 
  a 
  door 
  in 
  one 
  side 
  thereof. 
  

   The 
  lead-net 
  is 
  extended 
  beyond 
  the 
  stern 
  of 
  the 
  boat, 
  the 
  extension 
  

   being 
  connected 
  to 
  booms 
  anchored 
  and 
  hung 
  at 
  the 
  stern 
  of 
  the 
  boat, 
  

   on 
  the 
  sides 
  of 
  the 
  opening 
  therein, 
  by 
  swinging 
  which 
  inward 
  that 
  end 
  

   of 
  the 
  net 
  is 
  closed 
  as 
  the 
  same 
  is 
  elevated 
  to 
  prevent 
  the 
  escape 
  of 
  the 
  

   tisli. 
  The 
  extension 
  of 
  the 
  net 
  is 
  also 
  weighted 
  or 
  anchored 
  to 
  resist 
  

   the 
  action 
  of 
  the 
  current 
  by 
  means 
  of 
  iron 
  balls 
  and 
  chains 
  or 
  ropes, 
  

   with 
  the 
  ropes 
  or 
  chains 
  connected 
  to 
  the 
  extension. 
  An 
  oblique 
  brace, 
  

   of 
  which 
  there 
  arc 
  two, 
  has 
  its 
  upper 
  end 
  passed 
  through 
  the 
  slot 
  of 
  a
