Repetition mechanism for piano

摘要

The mechanism has a reduced resolution friction and bending resistance. On engagement the impact reed (402) acts upon a repetition lever (403) and only then the latter acts upon the hammer bar (140a). The structure is supplemented by a stop (416,417) for the repetition lever.On the repetition lever is secured a bending spring (413) which stitches the bending screw closely before the hammer has reached the string. Then it prevents the repetition lever to press the hammer against the spring.
