  • Patent number: 6390663
    Abstract: Mixing machine (10) for mixing or amalgamating varnishes, paints and the like comprising two coaxial shafts (14, 15) each one being operated by an electric motor (18, 20), a support (36) for a rotatable lower cap (29) that can be manually moved forward to load a can of varnish and cooperating with a top support (35) carrying a rotatable upper cap (28) to secure the can. The shaft (14) transmits the motion to the upper cap to turn the container about its longitudinal axis; the shaft (15) transmits its motion to a spindle (32) provided with worms (33, 34) in the ends thereof to approach or move away the caps. A fork (39) operated by the shaft (14) turns the caps about an axis which is perpendicular to the axis of the can of varnish. The can is therefore rotated about its longitudinal axis when secured between the lower cap and the upper cap and the can is turned about an axis which is perpendicular to the longitudinal axis of the can.

  • Patent number: 6193410
    Abstract: The invented apparatus can be used to agitate the liquid contents of paint balls to mix and evenly distribute their liquid contents so that the paint balls will fly in a true trajectory when shot from a paint ball gun. The invented apparatus also helps to remove or prevent the formation of dimples on the outer shell of the paint balls caused by sitting for extended periods of time in storage boxes, for example. The invented apparatus can thus be used to repair defective paint balls and to extend the useful life of such paint balls. The apparatus includes a support member, a motor, and a container. The motor is mounted to the support member, and the container is supported for rotation by the support member and the motor's drive shaft. Paint balls are placed in the container which is rotated by the motor during operation of the apparatus to move the paint balls to agitate their liquid contents. The invention also includes a related method.

    Abstract: An agitator for a paint mix tank is characterized by a paddle that has passages in it extending between opposite sides thereof and that is reciprocated up and down in the tank to keep the paint mixed and pigments and fillers in the paint in suspension. The paddle is reciprocated in the tank in linear directions generally along paths through its passages. Reciprocation is provided by a motor operating through a gearbox, and the speed of the motor is adjustable to control the reciprocation rate of the paddle. The passages through the paddle improve its agitation performance and enable its linear speed to be sufficiently low during agitation of the paint to eliminate foaming of and entrapment of air in the paint. A process is also dislosed for mixing the liquid contents of the tank without foaming and aeration by providing the above apparatus.

A drive motor is mounted on the main frame, and a container receiving and securing support is mounted on the subframe. A transmission mounted on the main frame operably connects the motor and the subframe, and converts the rotary output of the motor to a circular motion of the subframe. In operation, the circular motion agitates the fluent material in the container to mix it in a short period without producing the destructive forces leading to mechanical breakdowns associated with other mixers.

  • Patent number: 5727878
    Abstract: A flexible liner for use with a mixing container of the type having a bottom wall and a post extending inwardly of that bottom wall. The liner comprises a sleeve closed at its bottom end and open at its top end, and has a configuration generally complementary to the interior configuration of the container. The bottom end wall of the liner carries a fitment that has a tubular portion which has a closed top end and an open bottom end, and which has a configuration generally complementary to the configuration of the post. The bottom end of the sleeve has a hole in alignment with the tubular portion of the fitment. The liner is insertable into the container and conforms generally to the interior of the container, and the fitment fits over and receives the post. The tubular portion of the fitment receives a shaft that carries mixing blades for mixing fluids in the container. The flexible liner constitutes a barrier between the container and a fluid substance mixed therein.

  • Patent number: 5711601
    Abstract: Mixing apparatus develops a clamping pressure on a container to be mixed by bringing a pair of pressure plates together through the application of driving force developed by cranking a crank arm. A pawl and rachet arrangement prevents rotation of the crank arm in a direction which would loosen clamping pressure, unless a pawl unlocking knob is activated. Clamping pressure is limited by a clutch plate arrangement. Mixing apparatus is enclosed within a cabinet having a door interlock system which also automatically activates a brake for positively stopping further movement of the mixing apparatus.

  • Patent number: 5507575
    Abstract: An agitator for mixing or blending various products, in particular paints, varnishes or the like, disposed in a container, has a fixed support structure which is resiliently connected to a first framework which in turn supports a second framework in a generally oscillatory manner. An upper plate and a lower plate, rotatable about a vertical axis and mounted on the second framework, hold the container. When the machine is in use, an electric motor, mounted on the first framework, rotates a shaft provided with pins which are eccentric relative to the axis of rotation of the shaft and are connected to the second framework. The actuation of the motor gives rise to an orbital oscillatory motion of both frameworks together and the intermittent and unidirectional rotation of the lower plate about a substantially vertical axis. This promotes quick and homogeneous mixing of paints, varnishes or other such products in a broad range of quantities.
