Victorian illustration to download showing a crowd of men watching the demonstration of a bread-making machine. This large cast iron mechanism is worked by one man turning a wheel, which powers blades within the machine to knead the dough. A tray on top of the machine holds dough formed into loaves or rolls. A perforated cylinder holds flour for dusting the finished loaves. The wheel is geared so that the kneading speed can be varied. This demonstration took place in 1858. The machine was invented by Mr Stevens, who used it at his own bakery; he also invented small machines for family use.
