Patent model for divided type

Description (Brief)
This patent model demonstrates an invention for the method of casting divided type in order to prepare display type; the invention was granted patent number 200020. Display letters were to be cast in two parts so that a second line of type could be set between them, a style popular at the time. This invention was to replace the usual methods by which either a special block was engraved, or two forms were printed successively, each having the top or the bottom of letters masked off.
The patent was assigned to Carl Schraubstaedter and James A. St. John of the Central Type Foundry in St. Louis. The model and drawing advertised one of Central's products, "Copper alloy type."
