Abstract (en)
[origin: EP0357563A2] The pinion (15) meshing with the rack (16) drives, via the coupling (12, 13, 14), the arm supporting the bell. The detector (25, 27, 28) detects returns of the oscillating movement of the supporting arm, whereas the detectors (23, 24) detect a pressure threshold reached in the chamber (18b) of the twin pneumatic jack which drives the piston (17). The key valve (20) causes, when it is triggered, the starting-up phase of the ringing which lasts until the amplitude of the oscillation reaches a limit value and the push-rod valve (22) is actuated by a cam integral with the bell. The second phase is then a pealing phase. The third phase is a braking phase, triggered by the return of the valve (20) to the stop position. Lastly, the time-delay relay (21) causes the circuit to return into the starting position after the device has been stopped completely. <IMAGE>
