Branca Turbine Model

Description
Giovanni Branca, a chemist of Loretto, Italy, suggested a steam engine in which a jet of steam issuing from a nozzle was directed against the blades of a paddle wheel. This is the earliest suggestion of an impulse turbine.
The model, made for the U.S. National Museum, shows such a wheel connected to the pestles of a chemist’s stamp mill. The nozzle is attached directly to a spherical copper boiler.
