A proposed design of the steam laboratory for the greater Armour Institute of Technology . h. .41. SPECIFICATIOUS OF CLASS CDE LAVAL7EL0QITY-3TAGE TUI3II1L.

It is peculiarly fitted to operate withhigh pressure steam exhausting to atmosphere oragainst back pressure or with low pressure steamexhausting to condenser, hut it is also built tooperate with high pressure steam when exhaustingto condenser and as a mixed-flow turiine receiv-ing both high and lov pressure steam and exhaust-ing to condenser. Also especially designed to se-cure simplicity, accessibilit y, reliability andsafety. All interior parts ai-e accessible uponlifting the casing cover and withovit distxobingsteam or exhaust connections. All parts subjectto wear, such as , buckets and guide-vanesare independently renewable without necessitatingrenewal of larger expensive parts, A siiort,thick ,42,. shaft ia used to prevent vibration and the v/heelaare surroiinded by an impenetrable steel armor .Thewheels together v/ith the manner of attaching thebuckets, form a most important element in turbinedesign. The v/heels of De Laval class G tur-inesare forged steel disks, finished and polished onall surfaces and designed to withstand safely rota-tive speeds far in e:;eess of the normal speed ofthe tuibine. Ihey are cantered on the shaft byground disks and are secured by Vvoodruff keys. Aside from shaft bearings and valves,theonly parts of the class C turbine that are sub-ject to wear are the buckets and gtiide of wear of such parts is largely a mat-ter of supplying dry steam and of using proper ma-terials having suitable finish. The buckets of De Laval class 0 tur-bines are made of nickel-broniie by this processand are secured to the rim of the wheel by bulbshanks inserted into
