John Piehl from Richmond, Indiana, received a U.S. patent for an improved combination desk and seat. Patent no. 106403 was issued on August 16,1870.
This patent featured a school desk and seat that had a clam-hinge, holding the desk more firmly in place. This design created a longer lasting hinge. There are four cross members that form the folding seat. It has a swiveling book compartment, decorative brass supports, and is mounted on a wooden platform. The plate on the backrest is ripped off. There is storage underneath the desk, but the top does not lift up.
We are not aware of any additional information about the inventor/patentee.
