Abstract: A combined manual and power starting device for a gasoline engine which may be started by rotating the crankshaft thereof, the starting device consisting of a pair of rotary drive members operable respectively by manual and power devices, the manual device consisting of a pulley and a rope wrapped around the pulley to be pulled to turn the pulley in one direction to start the engine, so that the pulley cannot be turned by any device other than the rope without unwinding the rope therefrom, a power train connecting the power drive member to the crankshaft through a primary overrunning clutch, and a power train connecting the manual drive member to the crankshaft through the primary clutch, and also a secondary overrunning clutch, the secondary clutch being in series with the primary clutch but not in the power train from the power drive member to the crankshaft.

Abstract: A starting device for gasoline engines which may be started by spinning the crankshafts thereof, and comprising a torque transmission device consisting of a male friction cone adapted to be fixed in and turned axially by an ordinary electric drill device, and a matching conical female cup adapted to be affixed concentrically to an engine crankshaft and to receive the male cone therein so that rotation of the latter rotates the former to start the engine. A novel connection of the cone to the electric drill permits misalignment of the drill axis with the crankshaft, and damps the application of rotary force to the cup to avoid shocks to the system.
