US Patent 1991511, filed in 1933, shows a modern push-pin shape with a head made out of celluloid.

ETA: Also, previous push pins were made of glass, which could look quite similar to a plastic headed one. I didn't see any previous patents with a "modern" shape to them except one which had a roughly similar shape but a metal body.
