Crosshead Guides. A form of marine crosshead guide, differingfrom that ordinarily used in stationary work, is shown in Fig. crosshead used with thisguide is known as the slipper has but one bearing surface,and this runsin the space betweenSS and A. In the guide the plateP is bolted to the engine frameso that it receives all the cross-head pressure when the engine isrunning ahead. For backward motion of the engine the flangesFF are provided to receive the thrUst. Cranks. In marine work side cranks are not used. The con-necting rod is always connected between two crank arms.
