[Class 88 (ii)] In a miniature piano, the keys and sub-key levers are both formed as bell-cranks a, e and j, k respectively. An intermediate vertical lever may be arranged between the leverparts e, j, the latter being then arranged upwards instead of downwards, as shown. The lever-part k may pull downwardly on an extension of the wippen instead of thrusting it upwardly as shown.
