1. (Mech.) A rigid piece which is capable of turning about
one point, or axis (the fulcrum), and in which are two or
more other points where forces are applied; -- used for
transmitting and modifying force and motion. Specif., a
bar of metal, wood, or other rigid substance, used to
exert a pressure, or sustain a weight, at one point of its
length, by receiving a force or power at a second, and
turning at a third on a fixed point called a fulcrum. It
is usually named as the first of the six mechanical
powers, and is of three kinds, according as either the
fulcrum F, the weight W, or the power P, respectively, is
situated between the other two, as in the figures.

[1913 Webster]
Shepherds keeping watch by night. --Milton.
[1913 Webster]
All the long night their mournful watch they keep.
--Addison.
[1913 Webster]
Note: Watch was formerly distinguished from ward, the former
signifying a watching or guarding by night, and the
latter a watching, guarding, or protecting by day
Hence, they were not unfrequently used together,
especially in the phrase to keep watch and ward, to
denote continuous and uninterrupted vigilance or
protection, or both watching and guarding. This
distinction is now rarely recognized, watch being used
to signify a watching or guarding both by night and by
day, and ward, which is now rarely used, having simply
the meaning of guard, or protection, without reference
to time.
[1913 Webster]
Still, when she slept, he kept both watch and
ward. --Spenser.
[1913 Webster]
Ward, guard, or custodia, is chiefly applied to

[1913 Webster]
Note: Watch was formerly distinguished from ward, the former
signifying a watching or guarding by night, and the
latter a watching, guarding, or protecting by day
Hence, they were not unfrequently used together,
especially in the phrase to keep watch and ward, to
denote continuous and uninterrupted vigilance or
protection, or both watching and guarding. This
distinction is now rarely recognized, watch being used
to signify a watching or guarding both by night and by
day, and ward, which is now rarely used, having simply
the meaning of guard, or protection, without reference
to time.
[1913 Webster]

ward. --Spenser.
[1913 Webster]
