' -.By m.eans-: of. an' application of : tho woll-kno'wn gyroscope a railway vehiclo is made" to run on a "single; rail apparently withoutthe;slightest danger; of toppling ovori and wifh such stability as to "tako" sharp curves or remain- upright when not prppclled. An engineering correspondent of "The Tjihos," in tho; course of ;a-'([escription of the mono-rail veujclo inHUe'.model form, said: "The;gyroscopic,; action of heavy rotating masses j.s the principle employed. '-.A. tingle gyroscope' with freedom of motion'of the axle in a plane'at right angles-to that of the rotating:disc would' not suffice,, but by tho coupling of. two gyrosoopes together, by.moans'of .gearing, so that any angular deflection'of. one is communicated to the: other'in the reyerse direction, tlio sustaining force >is developed for. inclinations on Iboth sides of the verticlo.,Each gyroscopo is separately driven by an electric motor, and the current is supplied to the.motors by the.cells, which also' furnish- the propelling energy. 'In the full-sized Vehicle which the mvontor contemplatos,' ■ the cells of- the .model. wi(l, : of course,: be-stiporsedo'd'-by current supplied from a trolly or.other means in the ordinary way."
