A CROSSHEAD PER SE, AND IN COMBINATION WITH A CONNECTING ROD ASSEMBLY AND A PISTON ROD

摘要

The crosshead (14) has a body (18) formed of solid, metal plate, and of substantially U-shape. It comprises a pair of spaced-apart parallel limbs (20) which are bridged between by an integral transverse member (22), and the latter is bored (as at 24) through to receive a piston rod (16) therein. Shoe plates (26) are joined to the limbs (20) to guide the body (18) in reciprocation. In the combination with a connecting rod assembly (12) and the piston rod (16), the end of the piston rod (16) is directly fastened to the connecting rod assembly (12), and the crosshead (18) is coupled to an intermediate portion (50) of the piston rod.
