    levour, OF. leveor, prop., a lifter, fr. F. lever to raise,

    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.
    2. (Mach.)
       (a) A bar, as a capstan bar, applied to a rotatory piece

    {Lever watch}, a watch having a vibrating lever to connect
       the action of the escape wheel with that of the balance.
    {Universal lever}, a machine formed by a combination of a
       lever with the wheel and axle, in such a manner as to
       convert the reciprocating motion of the lever into a
       continued rectilinear motion of some body to which the
       power is applied.
