A mixing bucket holding means, subject of this petition for letters patent, consists of gripping jaws mounted on a platform/tray/frame holding a cylindrical bucket container in a manner to resist rotation of the container while a motor rotates a mixing paddle in the contents of the container. A human operator holds the mixing motor and space may be provided for the operator to stand on the frame. The claimed invention is to the combination comprising the cylindrical bucket holding means and the frame for mounting the bucket holding means. The jaws are easily engaged to grip the container and easily disengaged to release the container after mixing the contents. One version comprises two elastomeric bands facing one another. Movement of a lever causes one band to advance toward the other band so as to encircle the cylindrical container at its base region. A spring loaded latch holds the gripping force after the activating lever has been applied. A trip release of the latch enables a spring loading to retract the jaws. Another design places the bucket container cornered between two fixed stops while a third toggle member presses against the container to create a gripping force directed inward against the cylindrical container. Of other variations of the invention, each version has bucket clamping means, clamping means connected to a frame, and frame resting on the work area floor. Clamping means as taught by prior art include two jaw vise, three jaw chuck, collet chuck, pipe clamp, hose clamp, pipe vise, chain vise, strap wrench and more. The unique, inventive quality is the portable combination of any such clamping means with a frame which together can hold fast a mixing bucket of approximately five gallon size. The combination eliminates the hazard of a workman being injured by uncontrolled spinning of the bucket. If the bucket is held only by the legs of the human operator, relaxing of grip allows the bucket bail and handle to strike against the shin of the workman causing serious injury.
