Abstract: This invention is directed toward improved liquid sealing assemblies. The sealing assemblies are particularly useful in water control gates and in one embodiment have an elastomeric seal strip with a U-shaped cross-section defined by a web and a pair of arms extending transversely from the web. The seal strip is adapted to be fastened to a sealing location by mounting means located between the arms of the seal strip. The web of the seal strip is sandwiched between the mounting means and the sealing location, with the arms of the seal strip projecting just past the mounting means to effect sealing with their free ends.In another embodiment, the sealing assemblies have first and second elastomeric seal strips adapted to be mounted on two relatively movable members.

Abstract: A gate assembly has a frame with a sill and an opening for the passage of a fluid, and a gate slide mounted on said frame for movement toward and away from said sill, between open and closed positions. The improvement, in combination therewith, comprises a first flange projecting from the frame on both sides of the opening, a resilient sealing member fixed to the first flange, and a second flange substantially identical to the first flange projecting from the back side of the gate slide. The first and second flanges are so positioned that, when the gate slide is in the closed position against the sill, the first and second flanges overlap and the resilient sealing member is compressed so as to produce a water tight seal.
