Automatic Telephones

n1070.jpg (7945 bytes)The caseworks of this instrument is made of moulded black Bakelite which is easy to keep clean and does not become shabby through long usage. The micro-telephones are fitted with detachable receivers and "inset" transmitters. The ringers (1000 ohms) are fitted inside and apertures are arranged to permit clear audibility of ring.

This wall instrument follows the design of the table set immediately above.

The case is hinged at the bottom to a metal back upon which are mounted the induction coil, ringer, switch, condenser and terminals. The whole interior is exposed by undoing one screw only, and the apparatus can be removed as a unit without taking the instrument from the wall.
