reverse hanger derailleur?
another of those "what's the real name of this?" questions.
you know when the rear wheel dropouts face the rear of the bike, and you use a rear derailleur that clamps on the axel and the opening faces backward too? I've always called it a reverse hanger, but I guess that's not the real term 'cause I can't look it up on ebay or doing a quick google search.
I know they make (or at least made) them 'cause I have a couple, but need another for a new project. can anyone help me with the name of it, if I have it wrong? thanks.

No, the cost advantage is to use common parts ..
the Add on deraileur hangers have a small bolt hole in the back
That is for a clamp in the back of a Front opening dropout
Used on a rear opening one, like DaHon's Folding bikes
It follows the wheel into the dropout so sits in the back Open End.
It then keeps the RD hanger Piece in position .. the hanger still faces forward
held in place By the Wheel axle , mostly + the small bolt in the Back and it's D schaped nut.

Looks like the primary use is as a Emergency Replacement when you Break off the stock Derailler Hanger .
But it may be applied in the OP's case , If its a QR hub
Fyxation offers a whole Kit to put a Derailleur drive train on a Track frame
when the Fixie thing gets Old.

Track bikes don't have dropouts.

That's not what the people who sell framebuilding supplies say. E.g.:
