notes: label: Description (Brief)
content: This patent model demonstrates an invention for an artificial blast for typecasting machines; the invention was granted patent number 11955. This device was intended for small type molds, which were apt to overheat at fast casting rates. A blower, operated by a steam engine, drove air through a wooden tube around the casting room. Tin pipes from the tube supplied each casting machine with a double blast of air, one directed at the fuel to fire it, the second at the mold to cool it. George Bruce (1781-1866) followed his brother David to America from Scotland in 1795. The brothers first worked around the printing trades, and in 1816 set up their own type foundry. David retired in 1822 and was followed in the business by his son David Jr., author of the patents listed above.
