per three pieces are handled as one. the vertical jointsnever being disturbed after they have been once assembled. The turbine rests on four supports applied directly below the horizontal joints, on each side of the exhau.st chamber,and in line with the center of the exhaust opening. It is freeto expand axially, sliding on these supports, with the turbineanchored to the inboard generator pedestal. A system ofradial and axial stays in the exhaust chamber gives amplesupport for the spindle bearings and produces extreme rigid-ity in the whole structure, minimizing the possibility of dis-tortions with change of load, or due to external pressure. The low pressure rotor is composed of a central hollowdrum rigidly secured to spindle ends on each of which ispressed two blades or discs carrying the low-pressure blades.The maximum mean velocity of the blades is only 515 feetper second which precludes the necessity of using other thana good grade of cast steel in the blade rings, as the rotative

Fig- 2—Section through low-pressure double-flow turbine Stresses do not exceed 20,000 lbs. per square inch at 20 percent, overspeed. This has a distinct advantage over a designcontaining special grade steels, which are not only hard toget, even in normal times, but in the use of which a certainhazard is always taken, through the possibility of an unde-tected flaw, or some part not being up to specification, andbesides a little abuse in the way of improper heat treating ona highly stressed part may result in a costly failure. Owing tothe double flow feature, ample blade area is provided to takefull advantage of a high vacuum and still maintain a reason-able blade length in the last rows. Phosphor bronze bladesare used, except in the last three rows of the spindle, whichare drop forged steel. Automatic Cut-out One of the principal features of interest on this turbineis the means whereby, in case of necessity, either machinemay be automatically or manually cut out of service withoutdis
