The two rams of these cylinders pass through the ends of, and carry, a crosshead, upon which the main ram rests.
After the crosshead end is finished, the rod is reversed in the lathe for turning the piston end.
The piston rod and the crosshead obviously passed through its gun deck in a large hatch.
The crosshead was connected by two connecting rods to the side levers.
The test is made by removing the rod from the lathe and driving it tightly into the crosshead.
The crosshead of the reciprocating air pump is guided by a Peaucillier linkage shown at the center.
The strains are direct and the power and resistance are equalized by the inertia of the crosshead, piston, rods, and fly wheels.
A bar that forms a guide for the crosshead of an engine or other moving piece.
Alongside the steam cylinder is an air pump cylinder, also connected to the crosshead.
In Winwick Churchyard is a great fragment of a crosshead, consisting of the boss and two arms.
