The next figures show the valve-stem guides, rocking-levers, coupling-rods and gab, which latter when thrown over unhooks the link-rod, as is done on steamboat engines.
The following [figures] show the construction of the main bearing with adjustments on opposite sides, by which the shaft is kept in exact line, and shows also the solid support of the shaft quite out to the hub of the crank. This view contains one error. The cap is not made a binder. I relied on the strength of the thick continuous web of the bed under the boxes in addition to the depth of the bed. But we once had a bed break right here under enormous strain, and since then the caps have been made binders. It will be observed that the wedges are drawn upward to tighten the boxes. It is not necessary to explain why.
