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.
