Hey gang, this may seem a little weird.
While scrounging the local auto-surplus place I came upon a hydraulic servo
cylinder made (presumably for an airplane) built by THE ELECTRIC AUTO-LITE
CO. Build date April 1945. The build quality and construction (lightweight
aluminum alloy) scream aircraft to me.
The box reads "SERVO, 4" AUTOMATIC PILOT."
The part reads
PART 644231
MFD BY
THE ELECTRIC AUTO-LITE CO.
TOLEDO OH.
UNDER LICENSE FROM
SPERRY GYROSCOPE CO. INC.
The part was brand new in the original sealed box (marked - "Must be
recalibrated if installed after X month 1945"). I took it home with me after
shelling out 15$ in canadian pesos. I proceeded to dismantle it completely
to figure out how exactly this thing did whatever it did. Turns out it's
almost perfect to act as a hydraulically operated clutch for Valdez, since
he suffers from a pretty darn heavy clutch pedal. By doing a bit of clever
plumbing off the power steering circuit I should be able to use it.
My question is - any idea what kind of machine this might be off of? There
are many mentions of it being for an "S-4" automatic pilot. I don't know
anything about aircraft so I wonder if this is an obscure part or something
fairly common. It looks like it might actually be a retrofit.
I know there are a few very knowledgeable people in regards to things
pertaining to aviation on this list, figured I'd try my luck. I know it's a
long shot.
This information is basically just for kicks...
thanks
J-L
