This is an engineering technical drawing for a Bottom Corner Seal for Gate, prepared by United Engineering Company. The drawing is dated July 1950 and references Contract 4, with document number 203D1011R.

The drawing depicts a bottom corner seal assembly designed for gate applications, shown from an elevation view looking downstream with the right-hand configuration illustrated. The design includes multiple sealed cross-sections (SEC. A-A, SEC. B-B, SEC. C-C, and SEC. D-D) that detail various components including side seal keepers (Part #20SD and #20SD), a bottom seal keeper (Part #20SD), mitered joints for the side and bottom seals, and 4-ply nylon reinforcement. The main elevation shows a 21-inch width dimension and includes notes specifying that the unit shall be triple pressure tested with natural rubber seals, with specifications for materials including brass and composition materials. The drawing contains detailed dimensional annotations, cross-sectional views showing the internal structure and seal configuration, and assembly instructions for fitting the mitered joints. Technical specifications and material callouts are referenced throughout, along with fabrication notes regarding the reinforcement materials and assembly procedures required for this gate sealing component.
