inch deep and has a nominal diameter of 0 655 inch to provide a light press fit between adjacent pole segments 50 the pole segment 50 itself has a nominal cross sectional diameter of 3 4 inch and is formed from tubing as seen in fig4 the underside 20 of the base 12 has four holes 58 the holes 58 correspond vertically with the holes 48 the diameter of the holes 58 is preferably approximately 45 64 inch which is greater than the diameter of the reduced diameter section 54 of the intermediate pole segments 50 but smaller than the nominal diameter of the intermediate pole segment 50 returning now to fig2 and recalling that the steam generating unit is confined to the center of the interior of the base 12 leaving the peripheral portion open it can now be appreciated that the intermediate pole segments 50 are securely stored within the base 12 they are inserted in the holes 48 with the reduced diameter section 54 facing downward and extend through the base 12 through the holes 58 in the underside 20 of the base since the diameter of the holes 58 exceeds the diameter of the reduced diameter section 54 but is less than the diameter of the body of the pole segments 50 the pole segments 50 rest securely in the holes 58 and the holes 48 the upper pole segment 52 differs from the intermediate pole segments 50 in that instead of having a reamed opening 56 at the top end there is a narrow pin 60 which is used in connection with suspending the nozzle as discussed below the overall length of upper.
