     Mangle rack (Mach.), a contrivance for converting
        continuous circular motion into reciprocating rectilinear
        motion, by means of a rack and pinion, as in the mangle.
        The pinion is held to the rack by a groove in such a
        manner that it passes alternately from one side of the
        rack to the other, and thus gives motion to it in opposite
        directions, according to the side in which its teeth are
     Mangle wheel, a wheel in which the teeth, or pins, on its
        face, are interrupted on one side, and the pinion, working
        in them, passes from inside to outside of the teeth
        alternately, thus converting the continuous circular
        motion of the pinion into a reciprocating circular motion
        of the wheel.
