Sperry Gyro-Stabilizer
Installed in the engine room of USS Aramis (SP-418), "350
ton guardship and Admiral's barge in New York Harbor", circa
1920.
The ship's diesel engines are partially visible in the right
and left foreground, with the engine room workshop in the left
background.
"The little control gyro shown immediately over the main
gyro between the two tanks is the 'mind' of the equipment, and
acts to start the precession of the main gyro before the roll
of the ship takes effect. This photo shows the mounting of the
gyro in the ship on the two gudgeon bearings at either side which
allows the gyro to precess or turn in synchronism with the roll
of the ship." (quoted from the original caption)
