Electrical news and engineering . lbs. Theshipping weight of each turbine with its accessories is lbs. The water enters the turbine through concretescroll cases and will be guided into the movable guide vanesby individual stay vanes, imbedded in the concrete at their upper and lower ends. The stay vanes will be providedwith foundation bolts and adjusting screws at the upperend for adjusting the cast iron pit liners before pouring thercincrctc. The runner will have six blades, cast separately,and securely bolted to the runner hub. The operating gearfor the guide vanes will be of the oflf-set type, which dif-fers from the usual construction in that the guide vane lev-ers are offset from the radial position, and as the vanesclose the levers turn in a direction still further away fromthe radial position, resulting in a toggle action. This actiongreatly improves the speed regulation of the unit, due totlie fact that at large gate oiienings the movement of theguide vanes is greatest and the amount of this movement. Section through Generator decreases as the vane closes. Furthermore, as the guidevanes close the torque increases, reaching a maximum valuein the closed position where the hydraulic load is also The links connecting the guide vane levers witlithe operating ring are of the double-shearing :—The governors will be of the double floatinglevel type, with relay belt drive from the main shaft.
