US Patent 1,029,243. Metal-Pot for Type-Casting Machines and the Like
This is a 1912 United States patent specification by John S. Thompson for a metal pot used in type-casting machines and similar equipment, issued as a digital reprint from an Internet Archive type catalogue collection. Its pictures are patent drawings in black line, with two views of the pot and its mechanism labelled with numbered reference callouts. A designer might take from them the clean technical diagram style of early twentieth-century engineering, with numbered leader lines and exploded cross-sections.
