How Inventive! (No. 12)

By Dan

Do domestic chickens naturally see clearly? Probably, so these patented spectacles are purely defensive weapons — "designed for fowls, so that they may be protected from other fowls that might attempt to peck at them … [but] will not interfere with the sight of the fowl."

We have Andrew Jackson to thank for this patent, U.S. Patent No. 730,918. No, not the former President. So far as I know, Abraham Lincoln is the only U.S. President who is the inventor on a U.S. Patent (No. 6,469).
