Coin Operated Phone for Home (Mar, 1933)

Coin Operated Phone for Home
TO PREVENT excessive phone bills and to lessen the “Can I use your phone” nuisance, a coin-operated lock can now be obtained for either the French cradle type phone or the standard type. In operation, a nickel is inserted in the slot after removing the receiver from the hook and the plunger is pushed down with the finger.
The device can be applied in a few seconds to all types of standard phones. It is used in offices, stores and homes where, the meter system is employed.

    They need to invent a modern version of this for cell phones.
