Gassman, W J

This patent describes a improved double acting piston internal combustion engine. It comprises: a least one double acting piston positioned in an internal combustion engine cylinder having first and second combustion chambers located at opposed ends thereof, the at least one double acting piston having first and second piston heads on opposed ends thereof, the first and second piston heads communicating with the first and second combustion chambers respectively, and cam drive means operably associated with the at least one double acting piston, the cam drive means operably converting a combustion actuated reciprocable movement of the at least one double acting piston into a rotational drive movement, thereby to effect a rotation movement of a drive shaft means so that the drive shaft means functions as a power takeoff for the internal combustion engine, and further including cam groove means positioned in the cam drive means, the follower means operably engaging the cam groove means to effect the rotational drive movement, and wherein the follower means comprises a radially extending pin orthogonally positioned relative to a reciprocable movement axis of the at least one double acting position, and further including a drive ring means slidably movable over a circumferential surface of the cam drive means, the drive ring means retaining the follower means therein and directing the follower means into the cam groove means.
