that,  will  hold  the  pressure  at  250  pounds 
with  nozzles  that  will  spray  out  at  the 
rate  of  a  thousand  gallons  an  hour.  The 
engine  may  be  connected  to  the  pump  in 
various  ways.  It  may  he  set  with  the 
crank  shaft  lengthwise  of  the  wagon  and 
have  the  pump  crank  shaft  solidly  at¬ 
tached,  attached  by  a  di,sk  clutch  or 
geared  to  it.  Where  the  engine  is  set 
with  the  crank  shaft  across  the  wagon  it 
may  have  a  jack-shaft  and  pitman  to  run 
the  pump  with  or  without  a  clutch  on  the 
jack-shaft  gear.  It  may  be  geared  to  a 
jack-shaft  on  the  pump,  with  or  without 
a  clutch.  It  may  drive  the  pump  by  a 
chain  or  belt.  One  of  our  rigs  (the  best  I 
drives  the  pump  by  a  belt  with  a  heavy 
"idler”  to  keep  it  tight.  When  the  rig 
at  this  rate  the  changes  of  pressure  when 
opening  or  closing  the  nozzles  are  very 
great,  and  an  efficient  relief  valve  is  ab¬ 
solutely  needed.  If  one  does  not  work 
right,  it  is  very  poor  economy  not  to 
change  it.  The  common  types  of  rcli.ef 
valves  are  essentially  a  piston  or  plunger 
working  in  a  chamber  with  two  ports. 
A  spring  ordinarily  holds  the  end  of  the 
pisi<  n  between  the  inlet  and  outlet  ports. 
The  inlet  port  is  connected  to  the  air 
chamber  of  the  pump  so  as  to  be  subject 
to  the  working  pressure  of  the  liquid. 
The  outlet  port  is  connected  to  the  tank. 
When  the  pressure  gets  too  great  it  forces 
the  piston  back  against  the  spring  until 
it,  passes  the  outlet  port  and  lets  part 
of  the  liquid  back  to  the  tank.  Using 
lime-sulphur  or  Bordeaux  this  valve  is

was  new  the  bolt  was  quite  tight.  Thus 
was  all  right  until  the  pistons  began 
to  leak.  As  the  canvas  belt  got  wot  it 
drew  up  so  that  it  made  tlie  pump  bear¬ 
ings  heat  and  finally  the  belt  began  to 
tear.  A  longer  belt  was  put  on  and 
stopped  the  trouble.  Our  other  outfit  lias 
a  jack-shaft  and  pitman  with  a  dutch 
mi  the  engine.  It  is  satisfactory  except 
that  once  or  twice  it  has  been  necessary 
to  tighten  the  clutch,  and  this  is  a  very 
delicate  job.  A  fraction  of  a  turn  too 
much  on  the  set  screws  will  break  some¬ 
thing. 
The  Pump. — The  important  parts  of 
the  pump  are  the  pistons  and  valves. 
Ball  valves  are  sn  much  superior  that  no 
other  type  should  be  used  at  least  for  the 
outlet  and  inlet  to  the.  pump.  The 
valves  should  be  easily  reached  for  clean¬ 
ing.  In  many  machines  it.  seems  as 
though  the  designer  had  put  some  im¬ 
portant.  part,  where  it  eon  be  reached  only 
by  a  special  tool  which  is  not  likely  to 
be  in  the  ordinary  tool  box.  A  span¬ 
ner  may  be  needed  to  take  off  the  stuffing 
box  rings,  but  the  rest  of  the  pump 
should  be  so  that  it  may  be  com¬ 
pletely  dismounted  with  ordinary  wrench¬ 
es  and  screw-drivers.  One  spray  rig 
with  which  wo  have  had  some  experience 
has  one  of  the  cylinders  on  the  pump  so 
placed  that  the  packing  rings  can  be 
tightened  or  loosened  only  by  stopping 
the  engine  and  then  working  a  24-inch 
wrench  through  a  four-inch  opening.  It 
is  possible  to  turn  the  ring  only  about  a 
sixteenth  of  an  ip  oh  at  a  time.  Wear¬ 
ing  parts  in  the  cylinders  should  be  so 
arranged  that  they  may  be  replaced 
easily.  If  the  wear  comes  on  the  cylin¬ 
ders  they  should  have  removable  linings. 
Pistons  should  be  easily  changed  if  likely 
to  wear.  Where  a  piston  is  worn  it  is 
impossible  to  keep  it  packed,  and  the 
pr'c-e  of  a  new  set.  may  be  quickly  lost  if 
a  half  pint  or  so  of  spray  material  is 
thrown  out  at.  each  stroke.  Modern  spray 
materials  and  pressures  are  very  hard  on 
the  working  parts  of  the  pump. 
Pressure  and  Relief  Valve. — The 
capacity  of  the  pump  should  be  such  that 
the  pressure  can  be  held  at  250  to  300 
pounds,  with  a  nozzle  capacity  of  a  thou¬ 
sand  gallons  an  hour  or  more.  Working 
sure  to  get  filled  with  sediment  after  a 
time  and  get  to  sticking.  When  it  does  this 
it  is  no  longer  a  relief  valve,  and  should 
be  replaced  if  it  cannot  be  cleaned.  Oil 
sprays  do  not  attack  this  part  of  the  out¬ 
fit.  A  new  type  of  relief  shown  this 
Winter  at  Rochester  consists  of  a  dia¬ 
phragm  with  a  linger  which  almost  touch¬ 
es  the  ball  of  the  inlet  valve  of  the 
pump.  The  pressure  of  the  liquid  comes 
against  the  opposite  side  and  springs  the 
diaphragm  until  it  lifts  the  ball  and 
stops  the  pumping.  Tin's  has  several  dis¬ 
tinct  advantages.  We  have  not  tried 
it  and  do  not  know  where,  if  at  all.  it 
may  fail.  The  greatest  advantages  are 
that  il  apparently  cannot  clog,  and  that 
it  removes  all  pressure  from  the  cylin¬ 
ders  when  they  are  not  actually  pumning. 
This  should  greatly  increase  the  life  of 
the  pump.  With  all  other  types  of  relief 
the  pressure  on  the  pump-parts  is  kept 
up  at  all  times. 
IIose  Connections  and  Couplings. 
— Use  rubber  hose  only  where  absolutely 
necessary.  Many  manufacturers  will  at¬ 
tempt  to  sell  outfits  with  a  rubber  suc¬ 
tion  pipe  from  the  tank  to  the  pump. 
The  only  advantage  of  rubber  is  that  it 
is  flexible,  and  a  flexible  suction  pine 
is  not  needed.  The  hose  leads  from  the 
pump  to  the  spray  rods  should  be  re¬ 
paired  as  soon  as  they  start  leaking.  In 
many  eases  it  is  enough  to  cut  off  a  few 
inches  of  the  hose,  but  soon  the  whole 
piece  must  be  replaced.  It  is  poor  econ¬ 
omy  to  buy  cheap  hose.  The  nipples  that 
go  inside  the  hose  must  be  of  proper 
length  and  pattern.  The  nipple  should  be 
long  enough  to  permit  at  least  two  hose 
clips  to  be  used.  The  ordinary  corru¬ 
gated  kind  will  usually  hold  fairly  well 
with  Bordeaux  or  lime-sulphur,  but  for 
oil  sprays  it  is  essential  to  use  a  type 
tv '.tli  a  seat  for  each  hose  clip.  These 
seats  should  be  separated  by  bumps  so 
large  that  the  clip  will  hardly  pass  over 
them  when  drawn  up  tight.  When  put¬ 
ting  on  new  hose  it  will  be  found  ne¬ 
cessary  to  tighten  the  clips  a  few  times 
at  first.  A  cut-off  should  be  provided  at 
the  end  of  the  hose  nearest  the  pump, 
and  should  be  in  good  working  order  and 
easily  reached.  When  a  hose  blows  off 
much  snrny  material  will  be  lost  at  fe^.t
