Another Century-Old Invention Still In Use…

Posted by innovativeip on January 28, 2011

I love old patents, and I especially love “antique” inventions that remain relevant.  One has to wonder what portion of today’s innovations will remain in use 100 years from now?

Today’s Patent of the Day is U.S. Patent 982,593, issued January 24, 1911, to J.G. Griesinger for a “Loose Leaf Binder”. 

Issued January 24, 1911

This is not today’s discount store school supply three-ring binder, but is a sturdy spring post binder still common to professionals, such as for organization of real estate or other legal documents, or for sample books, such as for invitations.  The binders allow for page removal and replacement, yet deliver a “bound” experience during routine page perusal.  A simple, yet effective design.  Timeless qualities.

If you’d like to read the patent text, it is posted at, along with previous “Patents of the Day”.  Enjoy!
