herein may be utilized in connection with my
other systems. In one of those systems I
employ waves or flickerings of light for the
purpose of transmitting code-signals. In the
5present case I may employ the lamp E in a
similar manner, producing the initial changes
in current by the phonetic interrupter.
Should the pulsations of light be too rapid, the
adjustment of the fixed terminal and the 10dia-
phragm may be changed until the amplitude
of vibration is great enough to eliminate all
but the fundamental tones. In fact, the dia-
phragm may be weighted, if desired, or its
pulsations may be otherwise retarded. In
15case of transmitting by light-waves I use the
reflector and may also use screens of various
materials, such as slides of colored glass. And,
if desired, I may substitute for the lamps shown
a cathodic lamp of the kind described in my
20other application or other kind of light.
It will be observed that the most important
and, in fact, the essential feature of my in-
vention consists in the employment of a make--
and-break transmitter worked by sonorous
25vibrations, causing the transmitted electro-
magnetic or light waves to correspond closely
to the sound-waves by which they are pro-
duced.

30I claim, and desire to secure by Letters Pat-
ent, is--
