The pro-peller is car-ried on a crossshaft at the front end of a trussed U-shaped frame. This frame canbe revolved on a sort of vertical turntable or fifthwheel, and it is readily turned by means of a shaft carrying the propeller is driven throughbevel gears by a driving shaft running along one sideof this frame, and which is in turn driven by a spurgear and pinion from a central shaft turned by themotor. When it is desired to direct the airship up-ward, the propeller-carrying frame is placed in a ver-tical position (as. shown in the lower photograph),thus placing the propeller in a horizontal position andcaus
