AUTOMATIC ELECTRIC TYPE: An early Sydney workshop type introduced for use around
Sydney in the late 192O’s was the distinctively Automatic Electric instrument (Fig.13)
This public telephone was designed by local engineers to overcome the operational
shortcomings of earlier manual types and take advantage of the improved facilities
offered by the newly provided automatic exchanges. Some of the advantages listed for
the introduction of this type:-
a) Prevented use of bent or misshapen coins(washers).
b) Allowed coin to be inserted prior to connection and connection was automatically
made by pressing a button marked ‘service’.
c) The instrument had provision for coin return which earlier instruments
lacked.
This type was however, quickly abandoned probably due to heavy maintenance, and perhaps,
because the concept was too advanced for the existing exchange network of the
time. The mechanism was different to that already described and because it was little
more than an experiment will not be described here. Note the penny coin head which
was also widely used on other one penny coin collectors.
