  • the nipple 22 also serves as means to Aestablish constant communication between the chamber
  • the tubular wall portion 24 of the uppermost chamber 25 is secured to the tubular wall portion I9 by means of the nipples 26 and 21 in the same manner as the tubular wall portion I9 is secured to the tubular wall portion I6, and the nipple 26 serves to maintain constant communiycation between the uppermost chamber 25 and the intermediate chamber 20.
  • the nipple 23 is internally threaded to receive lthe threads on the pipe or conduit 28 which is open at both ends thereof and extends from near the top .of the chamber l1 to a point a slight f ldistance above the axis of the chamber 25.
  • Said chamber 25 is provided with end walls 29 which are Xed to the tubular member 24 in liquidtight relation to complete said chamber.

  • heating device thus being mounted on the one end wall I8 and extending longitudinally of the steam generating chamber I1 to adjacent the other end thereof.
  • a plu- 4 rality of the heating elements 31 is shown as being provided on the member 36 and said heater elements are made in such a manner that the heat produced thereby becomes more intense toward the free ends 38 of said members, the portions of said members 31 having the greatest heating capacity being located in substantially vertical alignment with the inlet end of the conduit 28, the steam generated ⁇ thus passing vdirectly into the inlet end of the conduit 28 and through the same into the receiving chamber 25.
  • the means for controlling the liquid level of 'water in the water receiving chamber 29 is illustrated as being a well known liquid level control unit 39, that illustrated being what is known as a McDonnell No. 47-2 Feeder-Cut-oiT-Combination manufactured by McDonnell & Miller, in which a iioat 40 controls the operation of a switch 4

  • the Water level in the float chamber 5I will be maintained at the same height as the Water level 46 in the chamber 20 when the regulator is functioning.
  • The" water level regulator of the type referred to is also provided preferably with a connection from the steam collecting chamber, a nipple 52 being fixed liquid-tight in one of the end walls 29 of theY chamber 25 to which a pipe 53 is connected screwthreadedly which leads to the upper portion of the float chamber, as will be obvious from Fig. 2 of the drawings.
  • the conduit 44 is connected with the outlet opening 54 in the regulator 39.
  • the top steam collecting chamber 25, which constitutes substantially a steam dome for the generator, is also provided with a safety valve 55 which is mounted on the screwthreaded nipple 56 that is iixed liquid-tight in the tubular wall 24, and with a cuplike member 51 which is connected with the valve 58 leading to the nipple 59 that is mounted in liquid-tight fixed relation to the tubular wall 24 and extends through the same so that boiler compound can be supplied to the steam generator to remove scale from the tubular members that form the same.
  • a suitable electrical conduit 62 extends Afrom the switch so as to connect the same in series with at least one yof the line conductors extending through the electrical conduit 63 to the terminal box 64 provided on the member 36 in a manner so as to control the supply of electrical energy to the electric heating members in accordance with the position of the contacts in the switch 6l so that whenever the pressure in the chamber 25 is below the desired pressure to be maintained, the switch 6l will close the circuit to the electric heater members, and as soon as the pressure of the steam in the chamber 25 reaches the desired maximum, the circuit to both of said heater members will be open so as to deenergize the same.
  • the maximum pressure at which the switch open-s is preferably set so that the switch will deenergize the electric heater elements 31 when the pressure in the chamber 25 reaches a predeterminedr value below the water pressure in the supply line 43.
