Patent Model for Molds for Casting Blocks for Printing Carpets or Wall Paper

Berry, James · ca 1854

This patent model demonstrates an invention for a mold that made blocks that were used in printing carpets or wall paper; the invention was granted patent number 10630. The design, formed of short and long pieces of type, was set up in a square casting box. The printing block was then cast in any suitable material such as type metal, plaster-of-paris, vulcanized rubber, or, by preference, gutta percha - a popular material in the mid nineteenth century.
