respectively the elements 30 31 32 and 33 are preferably constructed of aluminum which heats both evenly and quickly when steam is allowed to enter the channel such that substantial condensation is avoided on the sides of the elements 30 31 32 and 33 facing the chamber 40 the table 2 includes an upper planar surface 54 on a top 55 supported by legs 56 an intermediate shelf 57 is also connected to the legs 56 and utilized herein to support the steam generators 12 and 13 although the table 2 is illustrated in conjunction with the apparatus 1 in the illustrated embodiment it is foreseen that the apparatus 1 could be utilized in conjunction with virtually any structure having a substantially planar upper surface such as 54 capable of supporting the carpet 3 and apparatus 1 and also adapted to seal with the cover support structure 11 when the apparatus 1 is in the dye setting orientation thereof to prevent excessive escape of steam the hinge mechanism 16 comprises a pair of support struts 61 and 62 secured to opposite sides of the tabletop 55 near the back thereof an elongate pivot bar 63 extends between the struts 61 and 62 in spaced relationship to the surface 54 hinge elements 65 are secured to the rear element 31.
