[Class 88 (ii)] In an upright pianoforte of the type wherein a jack 6 is pivoted near the lower end of a wippen 4 actuated by a key tail 2, the jack carries a check 10 and is disengaged from the hammer butt 7 in a downward direction by the engagement of a projecting arm 6b with an adjustable stop 19, so that the check 10 is inclined towards the hammer and stops it almost immediately after it has struck the string. The damper 14 is moved by a rod 12 hinged to the key tail 2, and is returned by a spring 16.
