Milkshake machine

Milkshake machines are generally used in ice cream stores and fast food restaurants, and are not common as domestic appliances, where blenders are typically used instead.

The motor is connected to a vertical rod at the bottom of which is a small agitator of wavy metal or plastic.

[citation needed] Manual, crank-driven milkshake machines were introduced by James Tufts in 1884, under the name Lightning Shaker.

[1] The modern top-driven electric milkshake machine was invented by Frederick J. Osius in 1910, and commercialized by his Hamilton Beach company under the name Cyclone Drink Mixer.

[2][3][1] Hamilton Beach continues to be a major brand, as are Waring and Proctor Silex.
