The invention relates to known signal appliances comprising chime tubes which are fixed in a circle and chime by means of a centrally mounted, motor-driven striking element. The aim of the invention is to use a novel arrangement that omits striking elements, whereby space is saved, and uses chime tubes of essentially different diameters for producing very big differences in tone levels, whereby said chimes have constant lengths. Five chimes are suspended from a carrier plate. The carrier plate is swivelled around a predetermined area by means of the drive motor and a pinion that engages with the gear ring. The carrier plate is mounted on an axle which is fixedly arranged in a stationary holding device that is fixed to a vertical wall by means of screws. The inventive arrangement is especially useful as door bell or a glockenspiel.
A device for producing signal tones of different tone levels comprising chimes (2) suspended from a shared carrier plate (1) in an oscillating manner, said chimes ring when striking, opposing surfaces, said carrier plate (1) being rotatably held on an axle (6) that is rigidly arranged in a stationary holding device (3), said carrier plate being able to oscillate over a predetermined range together with the chimes (2) by means of a power transmitting element that engages on the carrier plate (1).
