Hi Dave

I happen to have in front of me a Siemens engine design of about
1860
with the same layout (with 4 cylinders), the only difference is
that
this one uses a bendy coupling, whereas the 1860 version used a
rigid
coupling with a ball pivot in the centre. As far as I can see,
anything else claimed (and there is a lot) is either baloney or
irrelevant to the patent, which is just the bendy bit. Siemens was
trying to invent the IC engine, the drive system wasn't the novel
part
of his design, it probably dates way back to the days when there
was a
patent on the crankshaft.

Steve

Am I missing something, or is the bendy bit actually superfluous ?
And I cant see how having a spring being bent like that would
contribute
any return of energy.

Dave

You are right, the bendy bit returns no energy. The mechanism doesn't
have the friction that might arise in a ball swivel, but the main
thing is that it might just be novel enough to gain a patent, unless
you can show someone used a bendy rod before. To patent something it
doesn't have to be useful, just novel, and on your own web page you
can claim anything else you like.

You don't even need a patent, but some people will add one to the
other and think the patent backs up the misleading claims - which it
doesn't - it just applies to the bendy bit.

Max efficiency of a heat engine is temperature difference divided by
the higher temperature (and we are talking degrees absolute here).
Minor variations in friction within engines is tiny compared to that
fundamental limit.

Steve

Its amazing how much money people must have spare. Patents are
not cheap (Ive looked into it for something Im developing), and
whilst
using a spring might be 'novel' the engineer in me cringes at the
claims
on the website....
Ive not built a swashplate engine, but I cant see how you even need
the
'bendy bit' There must be a pivot / bearing in the flywheel, which has
to
take the thrust. And as for not needing 'crossheads' whats that bolted
to
the back of the cylinders?

Hi Dave,

I like the grumpy old man with glass of wine attitude - can go for
that myself.

I have bunged a copy of the Siemens engine drawing from 1860 on the
web at
http://uk.geocities.com/oldnoccer@xxxxxxxxxxxxxx/Siemens/SiemensEngine1860.jpg

You will see the similarity (assuming the link works)

Steve

Isn't the Bendy Bit the steam pipe from the valves in the flywheel?
For more swashplate engines see "The Knife and Fork Man" by Bill Fairney,its
the story of Charles Benjamin Redrup.
