  pieces, 
  these 
  are 
  placed 
  in 
  the 
  breaks 
  and 
  business 
  proceeds 
  without 
  

   delay." 
  

  

  At 
  the 
  lower 
  ends 
  of 
  the 
  slide-pieces 
  C 
  is 
  a 
  frame, 
  II, 
  having 
  a 
  pin 
  at 
  

   its 
  upper 
  end 
  in 
  each 
  side 
  piece, 
  and 
  below 
  it 
  rests 
  on 
  the 
  floor 
  of 
  the 
  

   fish-way, 
  and 
  in 
  it 
  are 
  placed 
  two 
  or 
  three 
  grates 
  hinged 
  at 
  the 
  upper 
  

   ends, 
  the 
  lower 
  ends 
  being 
  loaded 
  to 
  keep 
  it 
  from 
  floating. 
  When 
  a 
  

   snag 
  or 
  stone 
  comes 
  through 
  the 
  road 
  these 
  open 
  and 
  let 
  it 
  go 
  through 
  

   without 
  breaking 
  the 
  grates. 
  The 
  grates 
  form 
  a 
  weir 
  to 
  make 
  the 
  fish 
  

   rise 
  toward 
  the 
  wheel. 
  This 
  is 
  necessary 
  on 
  account 
  of 
  raising 
  the 
  

   wheel 
  from 
  low 
  to 
  high 
  water. 
  The 
  wheel 
  is 
  inclosed 
  on 
  each 
  side 
  to 
  

   insure 
  the 
  fish 
  taking 
  to 
  the 
  way. 
  

  

  " 
  On 
  each 
  side 
  of 
  the 
  wheel 
  is 
  an 
  upright 
  timber 
  M, 
  on 
  which 
  is 
  

   uailed 
  a 
  strip 
  for 
  a 
  tongue, 
  D, 
  and 
  on 
  the 
  central 
  face 
  of 
  each 
  of 
  the 
  

   slides 
  C 
  are 
  two 
  similar 
  pieces 
  spiked 
  thereto 
  for 
  guides, 
  fitting 
  over 
  the 
  

   first, 
  and 
  on 
  the 
  side 
  of 
  C 
  next 
  the 
  wheel 
  (on 
  either 
  side) 
  are 
  two 
  

   wrought-iron 
  hooks 
  (not 
  shown) 
  which 
  pass 
  around 
  to 
  back 
  or 
  down- 
  

   stream 
  side 
  of 
  M 
  and 
  prevent 
  the 
  loose 
  sliding 
  pieces 
  C 
  from 
  becoming 
  

   disengaged. 
  C 
  is 
  always 
  on 
  the 
  upstream 
  edge 
  of 
  M. 
  At 
  the 
  top 
  of 
  

   M 
  a 
  cap, 
  K, 
  is 
  placed, 
  having 
  sheaves 
  L, 
  over 
  which 
  chains 
  or 
  ropes 
  

   pass 
  to 
  a 
  windlass 
  on 
  the 
  shore 
  for 
  raising 
  or 
  lowering 
  the 
  wheel. 
  

  

  ''The 
  wheel-arms 
  G 
  are 
  so 
  placed 
  that 
  they 
  meet 
  the 
  cross-pieces 
  

   supporting 
  the 
  ends 
  of 
  the 
  pieces 
  O 
  at 
  the 
  outer 
  edge 
  of 
  the 
  baskets 
  

   F, 
  where 
  the 
  arms 
  and 
  cross-pieces 
  are 
  clamped 
  together 
  with 
  a 
  piece 
  of 
  

   wrought 
  or 
  cast 
  iron, 
  N, 
  and 
  at 
  the 
  back 
  of 
  the 
  baskets 
  are 
  similarly 
  

   fastened. 
  The 
  pieces 
  are 
  all 
  bolted 
  together 
  wherever 
  they 
  cross 
  each 
  

   other, 
  and 
  so 
  form 
  strong 
  braces 
  for 
  keeping 
  the 
  wheel 
  firm. 
  

  

  " 
  The 
  fish 
  are 
  discharged 
  at 
  points 
  E 
  E, 
  on 
  the 
  shore 
  side 
  of 
  the 
  wheel, 
  

   behind 
  and 
  below 
  the 
  shaft, 
  by 
  sliding 
  down 
  an 
  incline. 
  (Shown 
  by 
  

   dotted 
  lines 
  in 
  Figs. 
  1 
  and 
  2.) 
  This 
  incline 
  is 
  a 
  board 
  floor 
  placed 
  in- 
  

   side 
  the 
  baskets 
  F 
  at 
  the 
  back 
  side 
  or 
  shaft 
  side, 
  and 
  in 
  such 
  a 
  way 
  

   that 
  the 
  fish 
  do 
  not 
  discharge 
  until 
  a 
  certain 
  point 
  is 
  reached, 
  when 
  

   they 
  slide 
  out 
  readily 
  into 
  a 
  box 
  placed 
  at 
  the 
  side 
  to 
  receive 
  them. 
  In 
  

   this 
  they 
  are 
  sorted, 
  and 
  the 
  small 
  ones 
  returned 
  to 
  the 
  stream. 
  The 
  

   sides 
  of 
  the 
  baskets 
  F 
  arc 
  made 
  of 
  strips 
  of 
  plank 
  screwed 
  or 
  nailed 
  on 
  

   the 
  inside 
  of 
  the 
  wheel-arms, 
  the 
  outer 
  ends 
  being 
  between 
  two 
  of 
  the 
  

   segments 
  O 
  and 
  the 
  inside 
  one 
  bolted 
  to 
  the 
  outer 
  one." 
  

  

  The 
  inventor 
  says 
  : 
  

  

  " 
  I 
  am 
  aware 
  of 
  many 
  forms 
  of 
  fish- 
  wheels, 
  but 
  that 
  in 
  which 
  my 
  in- 
  

   vention 
  consists 
  is 
  the 
  circular 
  and 
  partially 
  spiral 
  shape 
  of 
  the 
  bas- 
  

   kets 
  (so 
  that 
  the 
  fish 
  are 
  taken 
  without 
  injuring 
  them), 
  and 
  the 
  baskets 
  

   themselves, 
  made 
  of 
  pieces 
  of 
  wood 
  or 
  metal 
  in 
  the 
  form 
  shown, 
  with 
  

   the 
  slats, 
  arms, 
  and 
  braces 
  at 
  the 
  sides, 
  and 
  in 
  combination 
  the 
  slide- 
  

   pieces 
  and 
  rising 
  and 
  falling 
  grates 
  in 
  the 
  fish-road, 
  as 
  stated, 
  all 
  made 
  

   in 
  a 
  similar 
  manner 
  of 
  bars 
  and 
  slats."
