He’s using the telephone that lends an extra hand
For people who want to keep both hands free when they telephone, Bell Telephone Laboratories engineers have devised a new telephone with a sensitive microphone in its base.
To use it, simply press a button. The microphone picks up your voice and sends it on its way. Your party’s voice comes to you through a small loudspeaker. Both hands are left free.
The volume can be adjusted to suit yourself. If privacy is needed, you simply lift the handset; this shuts off the microphone and loudspeaker and you talk just as you would on a regular telephone.
This new development of Bell Laboratories increases the number of ways your local Bell telephone company can serve in businesses and homes.
