Well, being that that particular patent it title is: Coil For
Electromagnets, It is apparent to me, that he never intended this to
be a Tesla coil secondary. It could be useful for a primary coil
if you don't have the necesary primary capacitance to get your system
tuned, and have a limited amount of primary conductor for winding
that primary. For the size scale that Tesla built, It was likely
that he had a limited amount of primary cable. I seem to recall
reading in his CSN, that he would have parallel primary winding and
could choose to have them paralleled or connected in bifilar fashion
for a particular experiment.
The patent drawing shows a bifilar spiral coil but I can't find
any further statement about it or of any special properties attributed
Bottom line is that in 1894 Tesla apparently thought
self-capacitance was enough of a virtue to patent it. By 1916 he had
obviously learned otherwise.
