Abstract (en)
[origin: EP0459129A2] The invention relates to a mechanical return aid assembly for the actions of mechanical keyboard instruments, in particular for organs, with an arrangement for activating and deactivating this assembly. The assembly consists of a lever joint (6), which is activatable by means of the working travel of a pneumatically operated working bellows (3) integrated into a housing (2) and by means of the closing and opening movement of shut-off valves (4, 5), and of control cams (7). The lever joint (6) has a pull (8) which moves the actions (11) into the starting position and a control cam (7) connected to the valve (4) and adjustable by the latter and by the lever joint (6) is provided underneath the working bellows (3), a lever (9) which is connected to the actions (11), activates the valve (5) and can be brought into engagement with a tension arm (10) being arranged underneath the housing (2). <IMAGE>
