  • Patent number: 4230084
    Abstract: An engine starting device for starting an engine by connecting an output member on the side of a spiral spring and an input member on the side of the engine with each other when the force accumulation by the spring is released. A driving member is driven by the output of the engine. An automatic force accumulating operation for the spiral spring is driven by the driving member. A one-way clutch mechanism connects the automatic force accumulating operation means in a winding pressure accumulating mechanism for the spiral spring with each other.

  • Patent number: 3962932
    Abstract: Reaction moment, acting upon the crankcase of a conventional engine when the crankshaft is accelerated or decelerated, is minimized by the provision of a balance shaft carrying a weighted mass and arranged in parallel with the crankshaft and transmission means including a pair of intermeshing gears of an appropriate gear ratio mounted on the two parallel shafts. One of the gears in mesh is divided in two gear sections which is resiliently connected to the associated shaft normally to have an appropriate amount of phase shift therebetween to eliminate backlash.
