Jiffy Stand

Have I spouted off about this before?

When did people start calling kickstands "jiffy stands"?

Is that some deal from a regional vernacular I am not familiar with?  I mean, I kinda grew up around motorcycles.  They all had kickstands, just like every other bike I came across since.
Is there some historical context, that describes a kickstand as a jiffy stand in some old advertisement or brochure?

Jiffy stand.  Weird.
