THE FIFTH OF A SERIES ON QUALITY REPRODUCTION fc y WESTERN ELECTRIC The finest commercial gears in the world were not good enough M AKE us the finest commercially practical gears in the world," ordered the engineers of the Bell Telephone Laboratories of the most skilled gear manufacturers in this country. The gears were to be used to connect the disc turntable with the drive motor. But the gears — the finest which modern engineering could manufacture — failed to meet the exacting standard set. It was found that even they produced a mechanical vibration, causing a slight flutter or quiver in the reproduced voice and music. Less exacting designers of talking equipment would have said, "good enough" — but not the engineers responsible This mechanical filter irons out vibrations caused by the action of the gears between motor drive and turntable. for the Western Electric Sound System. The problem of removing this flutter and quiver was finally overcome by designing an ingenious mechanical filter which successfully irons out all the vibrations and jars which otherwise would be transmitted to the turn-table. This mechanical filter also reduces to a minimum the possibility of needle jumping. Because of such efficient refinements as this mechanical filter the Western Electric Sound System is acknowledged the best reproducer of sound pictures —setting the standard of quality reproduction. Because of such refinements theatres everywhere prefer to use this system. No Wonder the Standard of Quality Reproduction is the Wcsten SOUND Wlectric SYSTEM Distributed by Electrical Research Products fttc. 250 West 57th Street, New York, IS. Y.
