. American engineer and railroad journal . Fio. -DETAILS OF THE REGU-LATOR. rigid shafts would be heating in the bearings and a breakageof the shaft. M. de Laval lias overcome this difficulty in avery ingenious manner and with entire success, by utilizingthe gyrostatic properties of bodies and by mounting his wheelin a certain way upon a very small, and consequently veryflexible shaft. If a body which is symmetrical about an axis held at its ex-tremities and passing through the centre of gravity is made torevolve, it will tend, as its velocity isincreased, to turn about its axis of prin-cipal inertia, which is the line perpen-dicular to the plane and passing throughthe centre of gravity. The physicalaxis being flexible will take on thedeformation necessary to permit of thisadjustment, as shown in fig 23. Theposition of the disk which, for the sakeof simplicity, we have taken as an ex-ample, is a matter of no moment. Thisdisk may be at the centre of the axis,as in fig. 23, at a distance of one-thirdfrom one end, as in fig. 24, or on
