Abstract
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.
