Definitions

  • This invention relates to automatic icecream machines and in particular to an automatic ice creammaking machine of the kind in which an ice-cream mixture is contained in a rotatable refrigerated can provided with a rotatable helical blade arranged to exert a mixing action on the ice-cream mixture tangentially to the wall of the revolving can.
  • the rotating helical blade in order to obtain a goodmixing action, is required to scrape the can wall.
  • the end of the shaft carrying the helical blade and which is located in the can is usually supported by a ball bearing seated in a housing formed in a mounting member which is eccentrically arranged with respect to the shaft axis, so that by rotation of the mounting member relative to a stationary support therefor an accurate location of the helical blade relative to the can can be obtained.
  • the bearing for the end of the helical blade carrying shaft which extends into the refrigerating can is so located in a housing in a mounting member therefor that it is free to move radially relative to the housing and resilient means is located between the housing and the periphery of the bearing to maintain the helical blade in scraping relation with the can wall.
  • FIG. 1 is a diagrammatic view of an automatic icecream machine, the can of the machine being shown partly in section, and
  • FIG. 2 is a section illustrating a bearing for the lower end of a shaft carrying a helical blade forming a part of the automatic ice-cream machine shown in FIG. 1.
  • the helical blade 4 is rotated tangentially with respect to the inside wall of the can 1 so that during every turn thereof the blade 4 thoroughly scrapes ice-cream adhering to the inside wall of the can.
  • the end of the shaft 3 which extends into the can 1 is supported by a mounting member 5 which is accommodated in a cylindrical recess formed in a base plate 6 and whose axis is eccentric to the axis of shaft 3.
  • a mounting member 5 which is accommodated in a cylindrical recess formed in a base plate 6 and whose axis is eccentric to the axis of shaft 3.
  • the mounting member 5 forms a housing which seats a ball bearing 7 (FIG. 2) which supports the lower end of the shaft 3. Adjustment of the position of the blade relative to the can in the manner just described is adequate while the can 1 remains truly cylindrical throughout its length. However, it happens that sometimes the can may become deformed at some points. Should this occur then during the operation of the machine the blade 4 will violently strike such deformed points.
  • this disadvantage is removed or at least considerably reduced by providing a resilient member between the outer race of the ball bearing 7 and the housing in the mounting member 5 in which the bearing 7 is seated.
  • the resilient member is made in a manner such as to allow a lateral movement, of the order of about 1 millimeter, of the bearing 7, that is movement radially of the housing in the mounting member 5.
  • the mounting member 5 is, as stated above, provided with a circular recess in which the ball bearing 7 is seated.
  • the recess has a diameter greater than that of the ball bearing 7 and is divided into two annular grooves by an annular rib 8 whose internal diameter is slightly greater than the outer diameter of the ball bearing 7.
  • the grooves formed by the rib 8 are fitted with rings 9 and 10 of circular cross-section and made of soft rubber or similar resilient material which retain the bearing 7 in its seating by resilient pressure exerted on the bearing. If desired more than two rings may be used the grooves therefor being provided by appropriately disposed annular ribs similar to rib 8.
  • both resilient rings 9 and 10 are compressed, so that a lateral movement of the bearing 7, and therefore of the helical blade 4, is effected, while the pressure exerted by the rings 9 and 10 on the bearing 7 is sufficient to assure a correct scraping of the can by the blade 4.
  • the helical blade is continuously maintained in contact with the can walls, even at eccentric points thereof.
  • a resilient sleeve or like member for example a rubber sleeve, may be provided instead of the rings 9, 10.
  • an automatic ice-cream machine including a rotatable can and a rotatable shaft one end of which extends into the can and carries a can wall-scraping helical blade, and a mounting for said one end of the helical blade shaft
  • said mounting comprises a mounting member carried by a fixed part of the machine, a bearing seated in a housing formed in the mounting member and arranged to be movable in a radial direction relative to its seating, and resilient means interposed between the housing and the outer periphery of the bearing to maintainv the helical blade in scraping relation with the can wall.
  • a mounting according to claim 1, wherein the resilient means comprises a rubber sleeve.
  • a mounting according to claim 1, wherein the resilient means comprises at least two rings of circular cross-section made of soft rubber or similar resilient material.
