Dual motor drive automatic beverage brewing apparatus

A beverage brewing apparatus of the type having a brew chamber with a brewing component being shiftable relative to said brew chamber, drive means being operatively associated with said brewing component for controllably moving said brewing component in at least two orientations, said drive means comprising:

• a first driving assembly of said drive means shifting said brewing component in a first orientation relative to said brew chamber;
• a second driving assembly of said drive means, being selectively operable to drive said brewing component independent of said first driving assembly, for shifting said brewing component in a second orientation relative to said brew chamber;
• a sensor assembly being operatively associated with said drive means for sensing the position of said brewing component relative to said brew chamber and producing a control signal indicating the position of said brewing component;
• and
• control means being coupled to said sensor assembly and to said first and second driving assemblies for selectively energizing and deenergizing said first and second driving assemblies in response to predetermined conditions being defined by said control signal.

A beverage brewing apparatus of the type having a brew chamber with a brewing component being shiftable relative to said brew chamber, drive means being operatively associated with said brewing component for controllably moving said brewing component in at least two orientations, said drive means comprising:

• a first driving assembly of said drive means shifting said brewing component in a first orientation relative to said brew chamber, said first driving assembly of said drive means shifting said brewing component in a direction defining a linear path in said brew chamber;
• a second driving assembly of said drive means, being selectively operable to drive said brewing component independent of said first driving assembly, for shifting said brewing component in a second orientation relative to said brew chamber, said second driving assembly of said drive means, rotating said brewing component in said brew chamber about said linear path, independent of said first driving assembly;
• said linear path of said brewing component defining a central axis extending through said brew chamber;
• said first driving assembly including a first drive motor and a linkage operatively associated with said first drive motor, said first drive motor operating said linkage to act on said piston to shift said piston along said central axis;
• and
• said second driving assembly including a second drive motor and gear means operatively associated with said second drive motor and said piston, said second drive motor operating said gear means to rotate said piston about said central axis.

A beverage brewing apparatus comprising:

• a brew chamber assembly having a top assembly and a bottom assembly, said top assembly having a throat extending therethrough, and said bottom assembly having a drain extending therethrough, said throat and drain being generally axially aligned and defining a central axis extending therethrough;
• a piston being axially and rotatably shiftable through said throat and said drain;
• a linear drive assembly being operatively associated with said piston for controllably linearly shifting said piston along said central axis through said drain and throat;
• a rotary drive assembly being operatively associated with said piston, independent of said linear drive assembly, for controllably rotatably shifting said piston about said central axis;
• a sensor being operatively associated with at least one of said linear and rotary drive means for sensing positions of said piston relative to said brew chamber assembly and producing a control signal indicating a corresponding position of said piston relative to said brew chamber;
• and
• control means coupled to said sensor and to said linear and rotary drive assemblies for selectively energizing and deenergizing said linear and rotary drive assemblies in response to predetermined conditions corresponding to said control signal.
