Abstract
Several panels are pivotably mounted on top of a dam spillway for movement by air pressure provided through bladders downstream of these panels. The bladders are made from an elastomeric sheet that is folded so that edge portions overlap one another. A clamping bar secures these overlapping portions to the dam spillway. The sheet is also secured to the panel and defines the pivot or hinge joint for the panel. Abutments or stops on the clamping bar engage a strap, that also secures the bladder to the panel, so that the panel will not move upwardly beyond a limit position. An air operating system is disclosed for moving the panels in response to changes in the height or head of water upstream of the panels.
