With the old method the wire was

A telephone transmitter by Mr.. John
NJ. Graham, of Pittsburg, Penn, says
the Scientifc american, consists OF two
pairs of contact springs, arranged to
press opposite ends of electrodes carried
by springs bearing on the diaphragm,
one contact spring Of each pair being
connected with one terminal of the in
duction coil, the electrodes operated by
the diaphragm being connected with the
terminals of the local battery, whereby
the current in the local circuit is re-
versed during each vibration of .he
diaphragm.
