Mechanical appliances, mechanical movements and novelties of construction; a complete work and a continuation, as a second volume, of the author's book entitled "Mechanical movements, powers and devices" ... including an explanatory chapter on the leading conceptions of perpetual motion existing during the past three centuries. e peculiar in construction. Each consists of agun-metal sleeve prevented from turning by a loose-fitting dowel of this are three cylindrical tubes having a small clearancebetween them. These small clearances fill up with oil and permit aslight vibration of the inner shell, while at the same time restraining itfrom too great a movement. The shaft therefore actually revolvesabout its axis of gravity instead of its geometrical axis, as would be thecase with the bearings of the usual rigid construction. In case theshaft is a little out of balance the journal thus permits it to runslightly eccentric. The form of the rotating and stationary blades aremuch like those of the Curtis type, which are detailed in the followingcuts. The economy of the steam turbine has been greatly advanced byimprovements since its advent, so that it is now nearly in line with thebest quadruple expansion engines, and with it the highest speeds innavigation have been obtained. STEAM POWER APPLIANCES. 87. 3 . o < ?Z B I«0. 179. STEAM TURBINE. Curtistype, showing the arrangement of thesteam passages in the moving and sta-tionary blades in a three-disk engine. Claims are made that this type ofturbine with vacuum exhaust uses but12 pounds of steam per diverging nozzle is made of vari-able area by a slide valve and governor. A segment of one of the disksshown on a larger blades of the segmentsare cut in a milling machineof special design, and arebolted to the rim of the disk. A band incloses the outer end of theblades to prevent undue leakage between the disk and shell. 181. STEAM TURBINE. Multinozzle type. Showing position of blades
