  • Home rotary paint mixer
    Patent number: 4265548
    Abstract: A cage of spaced rods is proportioned to fit a gallon can of paint. A stand of formed rod supports the cage and an electrical, gear-reduction motor. The motor is connected to the cage, and a can of paint to be mixed within the cage is rotated about its axis by operation of the motor. A rotational speed of 25 to 30 revolutions per minute is fast enough to mix paint in a moderate amount of time with this inexpensive mixer.
