Patent - Fountain Pen Cap Construction

It's fun and interesting to see patents - the originals behind the pens we love so much now. This patent was filed by Lester W. Ormsby, for The Parker Pen Company. Looking at the patent, one may recognize a Parker-like appearance about it. This was a novel cap construction to allow venting in the interior to maintain pressure, but without drying out the nib.
