A venetian blind mechanism having a lead and a plurality of auxiliary carriers supported for traversing movement along a header between a retracted and an extended position and vane supports mounted on the auxiliary carriers for turning about an upright axis for light control. An operating chain is connected intermediate its ends to the lead carrier and has first and second chain portions extending lengthwise of the header in meshing engagement with sprockets on the auxiliary carriers to control spacing between the auxiliary carriers. Chain operating means is associated with the ends of the first and second chain portions for moving them in relatively opposite directions to effect rotation of the vane supports. A chain locking device is provided for automatically locking the chain to the sprocket on an auxiliary carrier when the carriers are retracted, to restrain movement of the operating chain by the chain operating means.
