4. In a wireless-telegraph apparatus. a cas-
ing, a source of light therein, a source of cath-
ode-rays therein, discharge - terminals for
Hertz-wave propagation, therein, means to
5control the production of the waves and rays,
and means to direct said casing toward a dis-
tant station.
5. A wireless telegraph, comprising a spark-
ing apparatus for producing Hertzian waves,
10means for actuating said sparking apparatus
at will for the purpose of signaling, means
for producing a cathode-light substantially in
the path of said Hertzian waves, and a receiver
sensitive to said Hertzian waves and located
15at a distant station.
6. A wireless telegraph, comprising a spark-
ing apparatus for transmitting etheric waves
into space, means for actuating said sparking
apparatus at will for the purpose of 20signal-
ing, a Crookes tube for producing cathode--
rays substantially in the path of said etheric
waves, and a distant receiving apparatus sensi-
tive to said etheric waves.
7. In a wireless-telegraph apparatus an 25ex-
ternal casing having a reflector and a source
of violet rays, the internal casing having dis-
charge-points and an element sensitive to light--
waves, means to impress changes on the waves
of light or those due to discharges from the
points, and connections from the sensitive30
element and the casings for the conveyance
of incoming waves or their resulting effects
to suitable receiving apparatus.
8. A wireless telegraph, comprising mech-
anism for producing cathode-rays, a sparking35
apparatus for producing etheric waves sub-
stantially in the path of said cathode-rays, a
manually-operated key for controlling said
etheric waves, and a receiving apparatus sen-
sitive to said etheric waves.40
9. A wireless telegraph, comprising a spark-
ing apparatus, a Crookes tube actuated there-
by, a reflector adjacent to said Crookes tube,
means for generating etheric waves within
said reflector, a telegraphic key for controlling45
the generation of said waves, and a receiving
apparatus sensitive to said etheric waves.
In testimony whereof I have signed my name
to this specification in the presence of two sub-
scribing witnesses.
