Regarding  U.S. ap    10/600036
 
Claims a hot air engine-powered rotisserie, roughly a heat driven spit.
 
De Vinci pondered and drew this one:

would have been a great non-patent citation.   Grin

Wow!  Cool!  A colleague once found Thomas Jefferson prior art, but I think this trumps that.
 
FWIW, there's enough stuff in the application to get around it, but Claim 1 looks like it's in trouble, assuming Da Vinci ever gets in front of the examiner.
 
Regards.

The case looks like it's been abandoned for failure to respond to the first non-final office action.

Maybe the inventor learned of the Da Vinci prior art and just gave up on the spot..  Smiley

No, the ap came to grief because of a prior U.S. patent.
 
I was scanning the titles of 99/$ aps and ran across the above and thought:  "hey, that's Leonardo's rig"
 
In New Orleans they have a kitchen antique store, a fabulous place for foodies like myself.  It's on the 600 block of Chartre in the French Quarter about a block from Jackson Square.  They always have at least one French made clock work spit in stock.  Fabulous contraptions, weights, pulleys, gears, escapements.  I've always wanted one.  They used to go for $1400.  Now $4500.   Sad
