发明名称 Restaurant telephone entertainment system
摘要 Disclosed are multiple combined telephone-speaker-lamp units for use in a restaurant having a telephone ordering system. A telephone switch board permits the feeding of a telephone conversation into the audio amplifier which drives the speakers so that a telephone conversation on other phones can be played on the speakers. The lamp blinks in response to telephone ringing current fed to the associated telephone. A lever-operated snap switch is responsive to the ringing current to blink the lamp. Each combined unit has a cable of sufficient length to extend via a hole in the table supporting the unit through a pedestal and past the pedestal's base to be plugged into the central cable system and then retracted beneath the base.
