Abstract
A device mixing ingredients for coloring hair includes a mixing bowl and a housing removably placed atop the mixing bowl so that a pair of agitators rotatably and coaxially mounted within the housing extend downward into the mixing bowl, being driven in opposite directions at the same speed by a mechanism powered by a hand crank, which can be turned in either direction to cause one of the agitators to move a liquid inward within the mixing bowl while the other agitator moves the liquid outward. In an alternative version of the device, the agitators are driven by an electric motor.
Claims14
Mixing apparatus comprising:
- a mixing bowl having an open top and a and a central lower portion having a flat inner surface;
- a housing, removably attached to extend over the open top of the mixing bowl,
- a pair of agitators, comprising an upper agitator including a tube rotatably attached to the housing, a lower agitator including a shaft extending upward within and beyond the tube, attached to rotate within the tube, wherein each of the agitators additionally includes a central hub pair of arms extending outward from opposite sides of the hub, with each of the arms including spaced-apart upward and downward facing flat surfaces extending between a pair of spirally curved mixing surfaces extending outward from the hub, including first and second mixing surfaces, each spirally curved in a common direction while extending outward from the central hub, and
- a drive, operatively connected to each of the agitators, causing the agitators to rotate at a common speed in opposite directions.
Mixing apparatus comprising:
- a mixing bowl with a round open top and a central lower portion having a flat inner surface;
- a housing including a lower cover, a ring extending downward from the lower cover within the round open top of the mixing bowl to hold the housing in place atop the mixing bowl, an upper cover including a truncated spherical surface extending outward beyond the mixing bowl to facilitate moving the housing upward, off the mixing bowl, with finger tips, and a handle, extending outward and downward to facilitate holding the housing,
- a crank, extending outward above the housing, attached to the housing to rotate about a crank axis of rotation;
- a pair of agitators, each attached to the housing to rotate about a common axis of rotation and to extend downward within the mixing bowl, wherein each of the agitators comprises a centrally disposed hub and a air of arms extending outward from opposite sides of the hub, wherein all arms within the agitators are identical, with each of the arms including spaced-apart upward and downward facing flat surfaces extending between a pair of spirally curved mixing surfaces extending outward from the hub, being spirally curved in a common direction, and wherein each of the upward and downward facing flat surfaces is parallel to the flat inner surface of the mixing bowl;
- and
- a drive, operatively connected to each of the agitators, causing the agitators to rotate at a common speed in opposite directions as the crank is rotated.
