ABSTRACT:
In an internal combustion engine, a combination of cylinders, pistons, rods, beams, gears and cams that are used for converting the reciprocating motion of the pistons into rotary motion of the drive shaft. One embodiment includes a block member that is fastened to four opposed in-line cylinders, that contain pistons that are attached to the ends of connecting rods and the opposite ends of the rods being attached to roller bearings and to the ends of two rocker beams. The beams, that oscillate in the same plane side by side, each have a separate shaft passing through their centers which are supported by the block member. Located at each of the two ends of the two rocker beams, there is a cam with shaft, that is placed between two of the roller bearings, and these two cams are connected by gears that cause the two cams to rotate in the proper position in relation to each other for the proper engagement of the cams bearing surfaces with the roller bearings. In an alternate embodiment, two rocker levers, which also pivot from their centers, have at one end a main cam with shaft and at the opposite end is placed a cylinder supporting two opposed pistons that are also between the ends of one end of the rocker levers. The improved features of construction includes a gear attached to the shaft of the main cam and this gear engages two gears placed opposite the main cam shaft gear, and connected to these two gears are shafts which are placed at the outer sides of the rocker levers. The shafts of the two outer gears have cams which are attached to them that engage the outer edges of the rocker levers and/or the rollers, urging the rollers attached to the ends of the rocker levers to make contact with the main cam.
