When part A is lifted when the key is struck and the pusher B acts on the hammer, the rocker C is lifted at the same time, which again acts on the adjustable stilt D, which is connected to the hammer L , until the rocker passes through the Stop F is triggered. The hammer is held by the usual catcher G after the pusher B is triggered by the stop ..//.

When the key is released, i.e. when part A and the parts attached to it sink, the rocker C at the front end is first lifted a little by the spring attached under its center, as a result of which the stilt D moves the hammer a little bit further leads to the strings and carries it for a moment, so that the pusher can be brought into its operative position by the spring M. As part A continues to sink, rocker C is released from stop F and is then held by pin K. The hammer can therefore fall back freely, while a new strike can still be made without the key being completely released.

In addition to enabling rapid repetition, the mechanics should offer the advantage that by the action of moisture on the instrument the type of playing is not as it is with others Mechanics is impaired. If z. B. lifted the buttons at the back by moisture and 'the hammers themselves led halfway from the drop bar to the strings have been, the mechanics should still be effective.
