Claims11
A mixing tool comprising:
- an elongated shaft having first and second ends, said first end being adapted for connection to a motor for rotating said shaft;
- and
- a link chain having an odd number of links, a central link of the odd number of links being fastened to the second end of said shaft for extension of the links radially from said shaft upon rotation in materials to be mixed.
A mixing tool for use with a hand held drill motor, comprising:
- an elongated shaft having first and second ends, said first end being adapted for connection to a hand held motor;
- and
- a link chain having an intermediate portion connected to said second end of said shaft to extend radially there from upon rotation of said shaft, the intermediate portion including a link attached to the shaft that is bisected by an imaginary plane perpendicular to the axis of rotation of the shaft.
A mixing tool for use with a hand held drill motor comprising:
- an elongated rigid shaft having one end adapted for being held in a chuck of a drill motor;
- a link chain having an odd number of links, a middle one of said links being attached to the other end of said shaft in a plane perpendicular to the axis of rotation of the shaft and such that the link chain extends radially from said shaft upon rotation of the latter.
