  opposite 
  to 
  the 
  base 
  plate, 
  to 
  bold 
  the 
  heads 
  at 
  a 
  

   proper 
  distance 
  apart. 
  This 
  tie 
  may 
  be 
  a 
  piece 
  separate 
  from 
  the 
  other 
  

   parts 
  of 
  the 
  frame, 
  in 
  which 
  case 
  the 
  frame 
  would 
  consist 
  of 
  but 
  two 
  

   pieces 
  ; 
  or 
  the 
  tie 
  may 
  be 
  produced 
  as 
  a 
  narrow 
  tongue 
  projecting 
  from 
  

   one 
  of 
  the 
  disk-like 
  portions 
  of 
  the 
  blank, 
  and 
  after 
  these 
  are 
  bent 
  into 
  

   positions 
  parallel 
  with 
  each 
  other 
  to 
  form 
  the 
  heads 
  the 
  tie 
  is 
  bent 
  down 
  

   to 
  extend 
  between 
  them, 
  and 
  is 
  secured 
  at 
  its 
  free 
  end 
  to 
  one 
  of 
  the 
  

   heads. 
  The 
  frame 
  would 
  then 
  be 
  composed 
  entirely 
  of 
  one 
  piece 
  of 
  

   metal.

  ; 
  trawl-roller.

  Plate 
  LXXI 
  II.) 
  

  

  By 
  making 
  the 
  trawl-roller 
  in 
  three 
  different 
  parts, 
  that 
  is, 
  a 
  central 
  

   one, 
  d, 
  and 
  side 
  rollers, 
  e 
  e, 
  all 
  secured 
  to 
  the 
  spindle 
  c, 
  a 
  very 
  strong 
  

   and 
  durable 
  trawl-roller 
  is 
  produced 
  from 
  smaller 
  pieces 
  of 
  lignum-vitae, 
  

   as 
  compared 
  with 
  a 
  continuous 
  solid 
  roller, 
  and 
  thus 
  pieces 
  of 
  wood 
  are 
  

   utilized 
  that 
  otherwise 
  would 
  be 
  wasted 
  ; 
  and 
  if 
  a 
  portion 
  of 
  this 
  roller 
  

   should 
  get 
  damaged 
  or 
  broken 
  such 
  injured 
  part 
  may 
  easily 
  be 
  replaced 
  

   with 
  another 
  at 
  a 
  small 
  expense, 
  as 
  compared 
  with 
  an 
  entire 
  new 
  roller. 
  

   By 
  securing 
  the 
  roller 
  to 
  the 
  spindle 
  and 
  locating 
  the 
  bearings 
  outside, 
  

   it 
  will 
  run 
  without 
  much 
  friction, 
  as 
  compared 
  with 
  rollers 
  running 
  

   loosely 
  on 
  a 
  fixed 
  spindle. 
  The 
  bearings 
  are 
  self-lubricating.
