McDonald's ice cream machine
The McDonald's fast food chain has used multiple ice cream machines at its various locations, but the chain has primarily operated those made by the Taylor Company. In 1956, Ray Kroc, who would soon become the founding owner-operator of the McDonald's franchise business, made a handshake agreement with the Taylor Company to supply milkshake machines for the fast food chain as its exclusive supplier.
