  — 
  An 
  automatic 
  arrangement 
  

   for 
  discharging 
  from 
  the 
  steam 
  heater 
  was 
  described 
  in 
  

   1910, 
  12 
  in 
  which 
  a 
  heavy 
  pendulum, 
  released 
  by 
  the 
  act 
  of 
  

   opening 
  the 
  calorimeter 
  jacket, 
  was 
  pulled 
  along 
  by 
  a 
  

   cord 
  attached 
  to 
  the 
  container.

  The 
  latch

  rotates 
  counter-clockwise, 
  

   pulling 
  its 
  bent 
  end 
  from 
  under 
  the 
  bail

  the 
  container

  the 
  divided 
  

   bar

  the 
  bail

  If 
  the 
  tops 
  of 
  L 
  and 
  E 
  are 
  in 
  the 
  same 
  plane 
  

   there 
  is 
  no

  tainer 
  was 
  thus 
  almost 
  unvarying, 
  was 
  rapid, 
  and 
  yet 
  

   slowed 
  up 
  at 
  the 
  end, 
  as 
  the 
  container 
  reached 
  the 
  water 
  

   in 
  the 
  calorimeter, 
  so 
  that 
  splashing 
  was 
  avoided. 
  At 
  

   the 
  end 
  the 
  container 
  was 
  released 
  by 
  automatic 
  tongs, 
  

   and 
  sank 
  by 
  its 
  own 
  weight. 
  This 
  arrangement 
  has 
  

   proved 
  to 
  be 
  all 
  that 
  could 
  be 
  desired, 
  but 
  the 
  special 
  

   pendulum 
  first 
  used 
  has 
  been 
  advantageously 
  replaced 
  by 
  

   a 
  simple 
  ball 
  and 
  cord. 
  At 
  the 
  top 
  this 
  cord 
  was 
  looped 
  

   over 
  a 
  bar 
  ; 
  by 
  sliding 
  it 
  along 
  the 
  bar 
  the 
  length 
  of 
  the 
  

   swing 
  could 
  be 
  quickly 
  and 
  easily 
  regulated
