Abstract

109,672. Pybus, P. J., and Phoenix Dynamo Manufacturing Co. Sept. 30, 1916. Aerial machines without aerostat; captive balloons; propelling.-Observation machines of the helicopter type, or captive balloons having helicopter screws and propelling means enabling them to cruise within the limits allowed by the cable, are driven by direct-coupled highvoltage electro-motors supplied through the connecting-cable from a source of energy on the ground or on board ship. Fig. 1 shows a helicopter having two screws 6 direct-coupled to induction motors 2 driven in opposite directions and controlled by a handwheel 3 acting on resistances. A parachute 9 is provided for the observer should the motors stop. Propelling-screws may be provided.
