John Long and Eugene Converse from Oswego, New York, received a U.S. patent for an improved school desk. Patent no. 117090 was issued on July 18, 1871.
This patent features an adjustable tabletop. The desk sits on two shafts that feature groves. The desk can be raised and lowered as it locks into place with the groves. The model is made of unpolished dark wood and brass. The backrest and seat do not join so there is no lower back support. The attached desk folds down and the horseshoe-shaped brass legs are attached to the bottom of the seat. A silver plate on the desk has "John Long and Eugene Converse, Inventors" engraved on it.
In 1874, John Long was recorded as working with furniture, presumably as a carpenter or manufacturer.
In 1866, Eugene Converse was registered as a gunsmith, locksmith, and ornamental fence ironworker.
