Device for extracting paste in particular from a kneading machine having a cylindrical vessel

A device for use with a kneading machine having a housing, a cylindrical vessel rotatable relative to the housing about a first vertical axis, a spiral kneading tool rotatable about a second vertical axis offset from the first vertical axis, and driving means mounted to the housing for rotating the kneading tool, said device comprising:

• a main cover having an edge with a first predetermined configuration;
• main cover pivot means for pivotably mounting said main cover to the housing for movement between a covering position in which said main cover is adapted to cover a major portion of the cylindrical vessel, and an access position spaced from said covering position wherein said main cover is adapted to allow access to the cylindrical vessel;
• an extractor arm having an edge with a second predetermined configuration complementary to said first predetermined configuration;
• extractor arm pivot means for pivotably mounting said extractor arm to the housing for movement between a working position in which said extractor arm is adjacent to said main cover when said main cover is in said covering position such that said edges of said main cover and said extractor arm are in a complementary relationship with one another, and a withdrawn position;
• paste extractor means, fixed to and extending from said extractor arm, for extracting paste from the cylindrical vessel when said extractor arm is in said working position;
• wherein said extractor arm pivot means further pivotably mounts said extractor arm to the housing such that said extractor arm is pivotable to an intermediate position between said working position and said withdrawn position;
• wherein an intermediate position covering means is associated with said extractor arm for covering, when said extractor arm is in said intermediate position, a portion of the cylindrical vessel not covered by said main cover when said main cover is in said covering position;
• and
• wherein said main cover pivot means and said extractor arm pivot means are respectively operable to mount said main cover and said extractor arm to the housing such that said main cover and said extractor arm are pivotable independently of one another and wherein said first predetermined configuration of said edge of said main cover and said second predetermined configuration of said edge of said extractor arm are such as to allow said extractor arm and said main cover to pass by one another when pivoted relative to one another.
