The inventor was born 16 May 1762 (or '63 or '64) in Amesbury or Newburyport, Mass. After being granted this invention, he moved to Charleston, SC, and engaged in shipbuilding, and was a captain in the militia, serving in the War of 1812. He drowned in the Stone River in 1818. As best we can tell, Quinby's grandfather (also Joseph Quinby) had owned a sawmill but we do not know what our inventor did before moving to South Carolina. This patent's specification and drawings were lost in the Patent Office fire of December 1836, and so little is known about this patent.
