Sorry Boris. I was being facetious. Lotsa gas and the name "Coffman"
reminded me of another RCM poster.
Best regards,

Gosh, Boris,
I guess you didn't like it.

I recall this thread happening about five years ago, and IIRC
it was indeed Gary who pointed out the real way those work.
I'm suprised he hasn't commented here.

The Martin B-57 (and the derivative RB-57) twin jet bomber. These were
USA made versions of the British "Canberra" bomber. The biggest obvious
difference was that the Canberra had side-by-side seating for the
cockpit crew, and the Martin version used tandem seating. All were quite
advanced light bombers for the time.
The RD versions were modified with far larger wings, for high altitude operations. They were sort-of an oversized U2, for photo reconnaissance spy missions, and high altitude research.

The man responsible was Roscoe Alexander Coffman and his first patent
for the starter was #1776228 granted in 1930. Breeze Corp made starters
under his patents. Bendix-Pioneer were also licensees.

I have seen some Chinese tractors with an interesting variation- its a
spring starter- you wind up a coil spring with a ratchet and then release it
to spin the motor over-

The original was a classic and heroic production. Thanks for the warning about
the 'cover version' I won't be tempted by it.

Different system. The Coffman style starter utilised the gas of
the cartridge to power the starter which rotated the engine.
The Marshalls used a cartridge vented into the cylinder head to
act on the piston to start the engine.

I saw the original Phoenix, and it was pretty bogus, too. Almost
anything Hollywood produces that has airplanes and flying in it has
some outlandish flight behaviour, pilot talk and mechanical setups. As
a pilot and mechanic, it gets painful sometimes. No wonder the
non-flying public is so misinformed and scared. I would imagine that
Hollywood hires technical advisors to keep the aeronautical themes
accurate, and then ignores their advice anyway. Got to make it
spectacular, you know.

How bogus was the original? The actually built a Phoenix and flew it. As I
recall, a stunt pilot got killed in a crash of the Phoenix during the
filming. Beg to differ. Both the book and the movie (original) were well
researched and totally feasible. How about some examples of these putative
errors?

Yep, that's the fellow. He's distant kin. His line and mine both come down
from John Coffman. John Coffman was the first blacksmith in Kentucky.
John's grandson Jacob was Roscoe's father.
Roscoe not only invented the Coffman starter, he also invented the first practical variable prop pitch mechanism. Roscoe's son Morris at one time owned a chunk of what is now the Vegas strip. He sold it to Howard Hughes in 1968. I once met Morris at a Coffman family reunion in Henderson Kentucky.
(We used to have huge family reunions held at Audubon State Park each August. Coffmans scattered all over the country would come back to attend. Sadly, that ended a few years after my father died in 1962.)
