Hand-cranked ice-cream maker
The first hand-cranked ice-cream maker, in which ice and salt chill the cream as it is churned.
Nancy Johnson, an American in Philadelphia, patented in 1843 a machine in which a container of cream and sugar is turned in a tub of ice and salt. The movement and the cold make the ice cream smooth and creamy.
The machine made it possible to make ice cream at home, which had earlier required much work. The design was used for over a hundred years, until electric machines took over.
Materials: Wood (tub), sheet metal or tin (container), iron (crank)
Manufacture: Patented by Nancy Johnson in the USA in 1843 and then made in many variants.
