Abstract
A two-armed lever which can be used as a rocker arm in the valve mechanism of a combustion engine has a central portion defining a rectangular passage for reception of a cam-actuated bearing on the rocker arm shaft. The first arm of the lever has a cupped motion receiving first portion which receives the complementary head of a push rod, and a second portion having an H-shaped cross-sectional outline and located between the cupped portion and the walls surrounding the passage in the central portion of the lever. The other arm of the lever has a first portion provided with an arcuate surface serving to transmit motion to the shank of an exhaust valve, and a second portion having an H-shaped cross-sectional outline and disposed between the first portion of the second lever and the walls surrounding the passage. The lever can be made by converting (by heating and extrusion or by drop forging) a block-shaped blank of steel into a second blank which is thereupon cold formed to more closely resemble or to constitute the lever.
