  side 
  of 
  the 
  base 
  of 
  the 
  engine. 
  The 
  tank 
  is 
  of 
  heavy 
  galvanized 
  iron, 
  

   fifty-six 
  inches 
  long 
  by 
  twenty- 
  six 
  inches 
  wide, 
  and 
  twenty-seven 
  inches 
  

   deep. 
  Its 
  capacity 
  is 
  one 
  hundred 
  and 
  seventy 
  gallons. 
  A 
  partition 
  

   runs 
  crosswise 
  through 
  the 
  middle, 
  and 
  each 
  section 
  thus 
  made 
  has 
  a 
  

   twelve-inch 
  opening 
  in 
  the 
  top 
  and 
  a 
  cap 
  for 
  the 
  same. 
  In 
  the 
  left-hand 
  

   corner, 
  toward 
  the 
  rear, 
  each 
  section 
  empties 
  through 
  an 
  inch 
  pipe 
  inta 
  

   the 
  system 
  leading 
  to 
  the 
  pump. 
  A 
  valve 
  on 
  this 
  pipe 
  admits 
  the 
  shut- 
  

   ting 
  off 
  of 
  the 
  section 
  from 
  the 
  feeding 
  system 
  at 
  will. 
  Another 
  valve 
  

   allows 
  the 
  direct 
  emptying 
  of 
  the 
  section 
  without 
  passing 
  its 
  material 
  

   through 
  the 
  pump. 
  Each 
  section 
  of 
  the 
  tank 
  is 
  provided 
  with 
  like 
  valve 
  

   and 
  arrangements, 
  and 
  contains 
  a 
  strainer 
  so 
  placed 
  that 
  all 
  liquid 
  pass- 
  

   ing 
  to 
  the 
  outlet 
  must 
  run 
  through 
  it. 
  

  

  Beneath 
  the 
  tank 
  are 
  two 
  sets 
  of 
  gasoline 
  burners 
  (Plate 
  III., 
  Fig. 
  2), 
  

   each 
  set 
  having 
  twelve 
  burners, 
  all 
  constructed 
  on 
  the 
  same 
  principle 
  as 
  is 
  

   the 
  common 
  plumber's 
  torch. 
  Gasoline 
  comes 
  to 
  them 
  through 
  a 
  pipe 
  

   on 
  the 
  right 
  side 
  of 
  the 
  wagon 
  from 
  a 
  tank 
  under 
  the 
  seat. 
  To 
  this 
  tank 
  is 
  

   attached 
  an 
  air 
  pump 
  and 
  a 
  pressure 
  gauge. 
  While 
  in 
  use 
  a 
  ten-pound 
  

   pressure 
  is 
  maintained. 
  By 
  means 
  of 
  valves, 
  one 
  or 
  both 
  sets 
  of 
  burners 
  

   maybe 
  in 
  use 
  at 
  one 
  time, 
  and 
  the 
  construction 
  is 
  such 
  that 
  each 
  burner 
  

   may 
  be 
  shut 
  off 
  or 
  caused 
  to 
  burn 
  low. 
  The 
  floor 
  of 
  the 
  wagon 
  under 
  

   the 
  tank 
  is 
  thickly 
  covered 
  with 
  asbestos 
  and 
  cement, 
  which 
  protects 
  the 
  

   wood 
  and 
  forms 
  a 
  foundation 
  for 
  the 
  pipes 
  which 
  support 
  the 
  sets 
  of 
  

   burners. 
  Within 
  the 
  iron 
  frame 
  are 
  two 
  side- 
  and 
  two 
  end-strips 
  of 
  gal- 
  

   vanized 
  iron 
  which 
  protect 
  the 
  burner 
  flames 
  from 
  wind 
  and 
  help 
  retain 
  

   the 
  heat 
  beneath 
  the 
  tank. 
  

  

  The 
  pump 
  is 
  of 
  the 
  triplex 
  type, 
  having 
  three 
  one 
  and 
  three-quarter 
  

   inch-cylinders 
  capable 
  of 
  a 
  two 
  and 
  a 
  half-inch-piston 
  stroke. 
  The 
  

   pumping 
  capacity 
  is 
  0.07 
  gallon 
  per 
  revolution 
  of 
  crank 
  shaft, 
  or 
  from 
  

   2.8 
  gallons 
  to 
  4.2 
  gallons 
  per 
  minute 
  when 
  run 
  within 
  recommended 
  

   speeds, 
  and 
  the 
  pump 
  will 
  operate 
  against 
  one 
  hundred 
  and 
  fifty 
  pounds 
  

   per 
  square 
  inch. 
  A 
  one-inch 
  feed-pipe 
  enters 
  from 
  the 
  tank, 
  which 
  is 
  

   elevated, 
  in 
  the 
  manner 
  stated, 
  above 
  the 
  body 
  of 
  the 
  pump. 
  The 
  dis- 
  

   charge 
  may 
  be 
  through 
  a 
  one-inch 
  pipe 
  or 
  through 
  the 
  series' 
  of 
  four 
  

   quarter-inch 
  cocks 
  arranged 
  on 
  a 
  cross-pipe 
  which 
  is 
  connected 
  with 
  

   the 
  one-inch 
  discharge. 
  The 
  belt 
  runs 
  on 
  a 
  twelve-inch 
  pulley 
  with 
  a 
  

   two 
  and 
  a 
  half-inch 
  face. 
  There 
  are 
  two 
  pulleys, 
  one 
  loose 
  on 
  the 
  

   shaft. 
  

  

  A 
  three-eighths 
  inch 
  pipe 
  is 
  connected 
  up 
  with 
  the 
  discharge 
  and 
  

   the 
  water 
  jacket 
  of 
  the 
  engine 
  cylinder, 
  and 
  this 
  cylinder 
  again 
  with 
  the 
  

   feed-pipe, 
  thus 
  allowing 
  a 
  flow 
  through 
  the 
  water 
  jacket. 
  The 
  rate 
  of 
  

   this 
  flow 
  is 
  governed 
  by 
  a 
  shut-off 
  valve 
  on 
  the 
  jacket 
  feed-pipe 
  near 
  

   the 
  cylinder. 
  When 
  only 
  two 
  quarter-inch 
  hose 
  are 
  in 
  use 
  this 
  valve
