Rittenhouse Ambassador E-403-B
This handsome chime from Rittenhouse featured a translucent Catalin Plastic cover and a night-light feature. This was a direct competitor of the Nutone Trinity door chimes. A three tube variant with the same case was known as the Embassy. The three tube variation played a six note melody. A 1939 electrical goods catalog described these elegant vintage doorbells:
The new Rittenhouse Ambassador models provide a chime for those who desire the finest in electrical chime signals.
The housing is made of a beautiful cast plastic producing a very rich effect. Its styling has dignity which will be found in good taste in homes everywhere.
Another special feature of this chime is the night light which is provided under the housing. The glow of this light shining through the plastic housing and down upon the tubes provides a striking effect. A cord pull-switch is provided so that the light can be readily switch on or off as features.
Mechanical features include a patented synchronous motor mechanism which governs the accurate timing of the chime tones. An important feature of this mechanism is the magnetic motor brake which insures positive operation and control. This is one of the exclusive features found only on Rittenhouse models. A volume control is provided so that the tone can be easily adjusted to suit individual installations.
