Abstract
A mixer is provided having a main frame and adjustable means for supporting the frame on the edges of a container. The frame serves as a mounting for a motor and a drive assembly, the latter converting rotation of the motor into simultaneous rotation of mixing blades and movement of the blades in an orbital path.
Claims11
A mixer adapted to rest on an edge of a container holding materials to be blended, said mixer comprising:
- a frame;
- means provided at one end of said frame for engaging the container edge at a first location;
- means projecting outwardly from opposite sides of the frame adjacent the opposite end thereof, said projecting means being adapted to engage the container edge at additional locations;
- a motor mounted on the frame;
- a drive assembly rotatably supported by said frame in sapced relationship with respect to said motor and a bottom of said container, said drive assembly being rotatable about a first axis and including a shaft rotatable about a second axis parallel to said first axis;
- means coupling the motor to said drive assembly for translating operation of the motor into rotation of the drive assembly about said first axis and displacement of said shaft in a path concentric with respect to said first axis, said shaft simultaneously rotating about the second axis;
- and
- a blade assembly secured to an end of said shaft and positioned between the drive assembly and the bottom of said container, said blade assembly being dimensioned to project outwardly from the shaft a distance greater than the distance between said first and second axes whereby rotation and displacement of the shaft results in turning of the blade assembly and movement of the blade assembly in an orbital path to encompass the area beneath said drive assembly.

A mixer adapted to rest on an edge of a container holding materials to be blended, said mixer comprising:
- a frame;
- means provided at one end of said frame for engaging the container edge at a first location;
- means projecting outwardly from opposite side of the frame adjacent the opposite end thereof, said projecting means being adapted to engage the container edge at additional locations;
- a motor mounted on the frame;
- a drive assembly rotatably supported by said frame in spaced relationship with respect to said motor, said drive assembly being rotatable about a first axis and including a shaft rotatable about a second axis parallel to said first axis;
- means coupling the motor to said drive assembly for translating operation of the motor into rotation of the drive assembly about said first axis and displacement of said shaft in a path concentric with respect to said first axis, said shaft simultaneously rotating about the second axis;
- and
- a blade assembly secured to said shaft whereby rotation and displacement of the shaft results in turning of the blade assembly and movement of the blade assembly in an orbital path, said blade assembly including a blade support member secured to the end of said shaft, and means joining at least one blade to said blade support member, said joining means comprising a flexible connection between a first point on said blade and a first point on the blade support member and a non-flexible connection between a second point on said blade and another point on said blade support member whereby said first point of the blade floats with respect to the second point.

- a frame;
- means provided at one end of said frame for engaging the container edge at a first location;
- means projecting outwardly from opposite sides of the frame adjacent the opposite end thereof, said projecting means being adapted to engage the container edge at additional locations;
- a motor mounted on the frame;
- a drive assembly supported for rotation about a shaft non-rotatably secured to the frame along a first axis, said shaft having a first gear fixedly secured thereto, the drive assembly including:
- an additional shaft rotatable about a second axis parallel to said first axis and a second gear secured to said additional shaft and engaging the first gear;
- means coupling the motor to said drive assembly for translating operation of the motor into the rotation of the drive assembly about said first axis and displacement of said additional shaft in a path concentric with respect to said first axis whereby the second gear moves with respect to the first gear to impart rotating to said additional shaft, said coupling means including means for converting the operating speed of the motor to the desired rotational speed of the drive assembly;
- and
- a blade assembly which includes:
- a blade support member secured to said additional shaft, at least one blade, and means joining said blade to the blade support member, said joining means comprising at least one connecting link pivotally connected between first points on said blade and the blade support member and a non-flexible connection between second points on said blade and the blade support member whereby said first point on the blade floats with respect to the second point on the blade, said connecting link being adjustably secured along a radially extending slot in said support member in order to vary the position of the blade with respect to the blade support member, said blade assembly being responsive to rotation and displacement of the additional shaft so as to move in an orbital path while simultaneously turning.
