Among the records of the Architectural Glass Patent Index, you’ll find several patents by Joshua King Ingalls, as well as a much greater number by his friend, associate, and fellow reformer, Thaddeus Hyatt. The illustration (taken from the site) is of a design by Ingalls, Patent 146,074, Dec. 30, 1873, for “Improvement in Illuminating Vault-Covers.”
