Directory Dials the Phone
A NEW desk telephone directory not only finds the number you want but actually dials it for you. All you have to do is slide the knob on the face of the device, called an Auto Dial, to the name you want, then press the small lever at the foot of the machine. When the lever returns to its normal position, in five or six seconds, your call is made and you pick up the phone.
The Auto Dial was invented by a German before the war. The only sample in this country is owned by Alfred Altman, President of the National Dairymen Association. The machine can handle any 50 telephone numbers desired by the user, and changes can be made at will.
The signals can be made up of any number of letters and digits, according to the system used in the local exchange. The regular hand dial on the telephone can be used in the ordinary way when the automatic device has been attached.
