  • Patent number: 4953985
    Abstract: An apparatus for mixing liquid paint colorant in a plurality of containers. Flexible cables are rotated about their length by a drive motor to rotate agitators in each container. The cable ends which drive the agitators are aligned with the rotational axes of the agitators. Each container has an open upper end which is closed by a cover having an attached mechanism for imparting rotation from the cables to the agitators. The agitators are disabled by disengaging one end of the cable from the drive motor, disengaging the other end of the cable from the mechanism on the container cover, or removing the cover with the cable intact to separate the mechanism from the agitator. The cables are bowed in an inverted U-shape between the drive motor and container covers. A lid extends over the bowed cables and has a rim that bears against the container covers to maintain them in closed position on the container during operation.

  • Patent number: 4941752
    Abstract: Improved mixing equipment of the wall-baffled, cylindrical, mixing-vessel type is provided. The novel baffles employed have a uniform cross-sectional form corresponding generally to a small geometric segment of a circle, the radius of which circle is substantially equal to that of the inner wall of said mixing vessel. A plurality (e.g., 2 to 4) of such baffles mounted at uniformly spaced locations around the periphery of said inner wall are employed together with a concentrically located, multi-bladed impeller capable of providing good axial and radial mixing within said vessel.The subject mixing equipment can deliver outstanding performance in terms of speed and completeness of mixing, as well as economy in power consumption and peak power requirements. Results are especially noteworthy when the equipment is used to mix chemical reagents (gaseous or liquid) with thick, non-Newtonian suspensions of solids and liquids; e.g., wet wood pulps and similar compositions containing fine, fibrous solid matter.

    Abstract: A paint cup adapted to be carried by a spray gun for use with coating materials requiring stirring to prevent separation. A reservoir is closed by a cover member which is mounted on the spray gun and, which in turn, mounts an agitator which projects into the reservoir. The agitator is driven by compressed air admitted to an impeller housing on the cover member. The reservoir is sealed except for means to introduce air to replace the coating material used in operation, and in this invention the air is introduced primarily through a separate check valve. Discharge ports in the impeller housing are made sufficiently large to assure at least atmospheric pressure in the reservoir. A separate check valve is provided to maintain the pressure within the reservoir at atmospheric pressure while preventing material leakage from the reservoir. The design of the cover assembly and its controls ensures easy flushing of the components with or without disassembly.

  • Patent number: 4398829
    Abstract: A can shaker kit includes a plate an elastomeric strap for holding the can against the plate so that vibratory motion of the sanding base of a vibrating sander is imparted to the can through the plate. Raised ribs are defined in the plate and strap to prevent lateral movement of the can relative to both plate and strap and, cans of various size can be accommodated. The ends of the strap have longitudinally spaced flanges integrally formed therein to secure paint cans of various heights.

  • Patent number: 4380398
    Abstract: A dispersion mixer is disclosed for breaking up and dispersing agglomerated particles in a liquid medium. The mixer has the capability of causing high speed particles to strike each other in such a manner as to develop their maximum shear energy potential and thus be more efficient than existing dispersion mixers. The mixer operates in a container and has a first rotor shaft extending downwards at the approximate center of the container, a second rotor shaft substantially parallel to the first rotor shaft, spaced from the first rotor shaft, at least one mixing rotor disc mounted on the first rotor shaft, and at least one mixing rotor disc mounted on the second rotor shaft, a first drive for rotating the first rotor shaft about its own axis, and the second rotor shaft about its own axis, and a second drive for moving the second rotor shaft in a circumferential path about the first rotor shaft.

  • Patent number: 4339992
    Abstract: A stirring apparatus includes a motive device, such as a motor, fixedly mounted on a support brace adapted to extend across the open top portion of a container. A paddle is connected releasably to a connector, which, in turn, is driven rotatably by the motive device. The paddle extends into the interior of the container for revolving about its axis for stirring the contents thereof. The support brace includes a device to enable the length of the brace to be adjusted longitudinally so that the brace can fit over different size container openings, and has devices for securing it releasably to the container. A plurality of different size interchangeable paddles are provided and each one is adapted to be connected removably to the motive means so that the paddles can be interchanged readily and can be cleaned easily.

  • Patent number: 4281936
    Abstract: A paint mixing and conditioning apparatus in which a paint filled container is simultaneously tumbled end over end while being rotated about its longitudinal axis. The container is clamped to a pulley shaped disc which is rotatably carried by spaced resilient wheels journaled in an upstanding plate. The container clamp is disposed to extend across openings in the upstanding plate and disc. The pulley shaped disc is driven peripherally by a resilient drive wheel coupled to a power source to tumble the container. A beveled friction wheel, coupled to the container clamp and in frictional contact with the upstanding plate, rotates the container as the pulley shaped disc is turned.

  • 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.
