An Engine of Death Able to
Distinguish Friend from Foe
Professor Montraville Wood of Chicago,
Illinois, has just come forward
with this invention which is—if it can
live up to the claims made for it—the
most remarkable war mechanism yet
imagined. The torpedo possesses
"ears" and a "brain" which enable
it to follow the peculiar hum of the
propeller of any vessel at which it is
unched, striking and sinking the •
aft no matter what the latter may
). If the vessel should stop, the
torpedo would stop also, submerging
to a certain depth; then when the
vessel started again — exciting the
torpedo's microphone ears by the
same sound—the deadly mechanism
would start its hunt again.
THE SECRET OF THE "BLOODHOUND" TORPEDO
The upper photograph shows the polished front surface of the torpedo. The two circular appendages on
the sides are the microphones. These, by means of electrical connections, connect with the propelling
and steering mechanisms. When tuned to the hum of any particular propeller, these microphones manage
the steering and propelling in such manner that the torpedo speeds surely to its mark.
