Spons' dictionary of engineering, civil, mechanical, military, and naval; with technical terms in French, German, Italian, and Spanish . back-water, as they cannot work under water (being supplied upon only a small portion of their circumference), and the hydro-pneumatic apparatus is not applicable to them. Turbines with a vertical axis possess adelicate part, namely, their pivot, which, if ithas to support too heavy a load, or if it turnstoo rapidly, is liable to become Thisdefect is of great importance in high-fall tm*-bines, the vertical spindle of which is often verylong and heavy, and has to carry besides theweight of toothed wheels or pulleys. M. Girardhas completely removed this difficulty by theapplication of two hydraulic pivots, representedin Fig. 4065. This pivot is placed at the bottomof the hollow spindle, that is, upon the floor ofthe lower mill-race. It consists of two cast-iron plates, P and P,provided with grooves. The upper plate P iswedged upon the bottom of the hollow spindleM, beneath the revolving wheel. The lowerplate P is cast with the part which receives the 4065. representedfrom which.
