Abstract
A device for preparing a beaten product and including a beater assembly driven rotatively about a generally vertical axis, with the beater assembly including a rotor body having vertically spaced upper and lower portions containing recesses, and a blade unit having upper and lower projections receivable within said recesses to connect the blade unit to the body, and with the blade unit being adapted for connection to the body by insertion of an upper one of the projections into an upper recess followed by swinging movement of the lower portion of the blade unit from a position in which a lower one of the projections is offset horizontally from a corresponding one of the recesses to a position in which the lower projection is above and can be moved downwardly into the lower recess.
Claims16
In apparatus for preparing a beaten product including a chamber into which the ingredients of said product are introduced, a motor, and a bearer assembly within the chamber driven rotatively by said motor, an improved beater assembly comprising:
- a rotor body driven by said motor rotatively about an essentially vertical axis and having a generally vertically extending portion and vertically spaced upper and lower portions projecting laterally therefrom;
- and
- at least one blade unit detachably connectable between said upper and lower portions of the rotor body and including a generally vertically extending structure and angularly disposed blade means projecting outwardly therefrom toward a side wall of said chamber to beat the ingredients as the assembly turns;
- said upper portion of the rotor body having a first recess facing downwardly, and said lower portion of the rotor body having a second recess facing upwardly;
- said blade unit having an upper projection adapted to extend upwardly into and be retained within said upper recess in a predetermined connected position of the blade unit in which it is carried and supported by the body, and having a lower projection adapted to extend downwardly into and be retained within said second recess in said connected position of the blade unit;
- said body and said blade unit and said projections and recesses being constructed and dimensioned to enable movement of the blade unit upwardly and downwardly between said connected position and an elevated position in which said upper projection remains in said first recess but said lower projection is above the level of and withdrawn upwardly from said second recess;
- said blade unit in said elevated position being free for swinging movement of said lower projection horizontally between a location above said second recess and an offset position in which the blade unit is insertable upwardly into and removable downwardly from said upper recess for rapid detachment of the blade unit from and rapid attachment to, the body.
In apparatus for preparing a beaten product including a chamber into which the ingredients of said product are introduced, a motor, and a beater assembly within the chamber driven rotatively by the motor and having blade means, the improvement comprising:
- a product discharge element connected to the lower end of said beater assembly and having at least one arm extending generally arcuately about the axis of rotation of the beater assembly and advancing downwardly to an extremity of the arm, said arm having an under surface which presses downwardly against the delivered product in a container thereof and shapes the upper surface thereof, said under surface of the arm near said extremity thereof having two radially spaced generally coplanar portions and an intermediate portion radially between said spaced portions projecting downwardly beyond the common plane thereof to form a circular depression in the upper surface of the product.
