3Q 12, 13, and 14. A tank, indicated generally bythe Vnumeral 15, is provided having av well 16 and a longitudinallyv extending portion 17, as shown clearly in Figure 1. The tank is provided with a perimetrical ange 13 having a depending portion V'19. As shown in Figure 3, the flange 18 on Y the right hand side of the tank is at an elevation lower thanthe portion on the left hand side of the tank, While theend portions of the ange at an angle as indicated by dotted lines Vin vsaid Figure 1. The flange 18 with the depending .por` tion 19 serves to entrap products of vcombustion and unconsumed gas and to conduct the same I .around the tank to the pipe 20 which is provided with an enlargement 21, by means of which such gases are conducted from the proof box. The diameter of the enlargement 21` is suniciently large to catch the gases escaping from the opening 18a during the slight to and fro movement of the tank which takes place during the use'of the apparatus. A e The arm 12 ofthe base 10 maybe' provided with a vgroove 12a'in its'uppersurface, asshownwin,`

If the arm 26 is over the full steam legend,

the operator will know that 'the burner 25 is ap-f proximately inthe position shown in Figure 2,

while if the arm` is over thehalf steam? legendhe will known that the burner is slightly removed Vfromlbeneath the'tank although in -sufellposii`- tion-that a small quantity of steam will be;pro'

duced. When the arm 26`is'over the dry neat legend the burner 25 is entirely removed from be# neath .the tank and serves to provide dryheatl for the proof box,1but1,not steam: As is shown-in FigureS, a baffle 43 vserves to protect the tank 1'5 From theabove it 'will be seenthatV a very comlpact humidifier has been provided'in which'a float controlled valve vhas been eliminated, which 'in the past has beenv thel source of considerable dif` culty in that waterdeposited material frequente ly caused the valves toclog :and the tanks thus to burnout. 'It will also; be apparent that vthe tank 15 can bei removed for cleaning or replace` Y ment'without the use of 'anytools since it merely rests upon the arm 12, being limited in its rocking movements by they stop 22 andthe valve 33.
