The Civil engineer and architect's journal, scientific and railway gazette . ter S,carrying two little weights /; h at its ends, and fixed horizontallyacross the top of the spindle by the middle part of the spring,which fits into a cleft in the to]) of the spindle, and is secured by asmall nut. When the spindle is made to revolve too fast, theweights at the end of the spring fly outwards by their centrifugalforce, and begin to touch and rul> against the sides of the circularbox I, which friction checks the motion. This description of go-vernor ))reserves the motion more uniformly than the ordinary sortof fly, which acts by the resistance of tlie air. Just below thiscentrifugal governor there is a cross-piece ), inserted through atransverse hole in the spindle X, so that when the spindle is at itsmedium degree of elevation, that is to say, when its two pinions Vand W are neither of tliem in gear with the crown-wheel, the endsof the cross-piece i meet a stop /c, which may project from any fixedpart of the apparatus, such as the cone D, and so stop the revolu-. geared tions of the spindle ; while, as soon as the spindle is raised or , the cross-piece i no longer meets the stop k, but passes overor under it, amd allows the spindle to commence its revolutionsjust before one of the pinions gears into the crown-wheel. Thespindle X is actuated and kept with a constant tendency to revolvein one direction by a toothed wheel Z, keyed on to it just below themiddle plate F, and this wheel is driven by a train of wheelworkW, supported lietween the middle and bottom plates F and G,similar to ordinary clockwork, and which is driven by a spring in abarrel /, acting on a fusee vi, driven by a cord or chain; or thewheelwork may have any other contrivance as its prime mover, as,for instance, a common barrel with a cord and weight. The wheelZ is of such thickness that the motion up and down, which thespindle X admits of, will not ungear it from the next wheel in thedriving tr
