Tainter Valve Side Seal.pdf

This is a technical drawing/blueprint for a side seal gate for a McNary Lock & Dam, prepared by Union Engineering Company. The document is marked as Contract 4 and includes detailed mechanical specifications and assembly instructions for the gate seal system.

The drawing depicts a 12-foot-0-inch wide gate seal assembly with 4-ply nylon duck reinforcement. Key specifications include 45-degree angle cuts on the sides, drill holes at assembly using side seal keeper strips, and right and left hand designations determined by drilling at assembly. The blueprint contains notes regarding rubber and reinforcement materials, compression specifications, and dimensional tolerances. The document is dated May 1950 and includes manufacturer signatures and certification stamps. This appears to be a historical engineering specification document rather than a solicitation or contract opportunity document.
