US Patent 1,026,185, Type-Casting Machine
This is a 1912 United States patent specification for a type-casting machine, filed and granted to John S. Thompson, reprinted digitally from the Internet Archive's type catalogues for engineers and printing-trade readers. Its two pages of patent drawings show mechanical assemblies with numbered parts, perspective views and sectional elevations of the casting mechanism, with labelled reference lines that a designer could use as a diagrammatic, technical-drawing texture.
