This series contains a multitude of patents, trademarks and correspondence, as well as blueprints of a nailing machine, two Orchard King Citrus labels, trademark republications and renewals. The correspondence includes official certificates from the Washington Patents Office to the inventors of citrus labeling mechanisms from 1926-1930 and renewals of various apparatus for painting or stamping. It also contains two undated Canvas Handling Mechanism blueprints by E.E. Evans and official letters patents from 1929-1931 between Evans and the Riverside commissioner of patents for the canvas handling mechanism, automatic box stamping machines and devices. Although the blueprints are untitled and undated, the figures can be inferred from his correspondence with the Washington States Patent Office. This series also includes documented communications between Jackson, Midas, Minier & Fihe trademark and patent bureaus with Orchard King and Covina Orange Brand Trademarks and contains miscellaneous material such as: incomplete patent applications (both signed and unsigned) business cards, letters, a booklet and the envelopes themselves that contain the topical material.
