  • Piston rod-connecting rod interconnections for internal combustion engines
    Patent number: 3971355
    Abstract: A piston has a pair of support members extending away from the piston head offset from a piston ring portion, a piston rod being carried on a connecting rod which is clamped between the support members by a bolt. The bolt is loosely received in a bore in the connecting rod, the force between the piston and the piston rod being taken by a frictional force between the connecting rod and the support members to prevent a bending force being applied to the bolt.
