The Sailor's Word-Book

In the marine steam-engine, the lever and counter-balance weight are fixed upon the wiper-shaft, to form an equipoise to the valves.


There is one on each side of the cylinder. (See spanner.)

Also, an inflexible bar of iron or wood to raise weights, which takes rank as the first and most simple of the mechanical powers.

♦ To lever. An old word for unloading a ship.
