The helical blade stirrer of an automatic ice-cream machine is as is customary located for rotation in the refrigerating can to be tangential thereto so as to scrape the side of the can. To accommodate deformation of points on the side of the can without permanent re-location of the helical blade the bearing for the end of the blade shaft which is located in the can is arranged to float radially in its housing and is maintained in the housing by resilient annular means such as rubber rings interposed between the housing and the periphery of the bearing. |
