Abstract: Adjustable coupling device for driving a stirrer rod shank of devices including a stirrer lid positioned on a tin of paint located in a paint stirring machine. A first tube has an upper fork capable of being coupled to a shelf drive plate of the stirring machine, and a second tube whose height is equivalent to that of the first tube has a reduced diameter so that it can slide at a slight clearance within the first tube, with the stirrer rod shank projecting from the stirrer lid so that it can slide with a clearance along the second tube.

Abstract: The invention relates to a machine for stirring paints.This machine is of the type comprising support racks (3) of cans of tints provided with an upper stirrer lid (5), and a mechanism for driving the stirrer lids on each of the racks, the stirrer lids (5) each being provided with a motion take-up pinion (27) for the stirrer shaft inside the cans. It is characterized in that said mechanism for driving the stirrer lids brings into play a set of endless screws (29) mounted one on each of the racks, these screws each coming to mesh with the driving pinions (27) of the stirrer lids of a same rack and being driven at an adequate speed of rotation, which is variable depending on the range of the cans of tints of the racks.
