These are technical engineering design drawings for a Tape Sheave component, part of a federal contract (Contract No. F41608-80-G-0037-0029) issued to E.W. Bliss Company. The four-page document contains detailed mechanical specifications and technical diagrams for multiple related components including an End Plate, Deck Sheave, Shaft, and Sleeve, with precise dimensional measurements, manufacturing notes, and engineering specifications. Each drawing includes specific technical requirements such as material specifications (e.g., ASTM-A108 steel), surface texture standards (ANSI B46.1-1978), cadmium plating specifications, and notes for breaking sharp edges and maintaining dimensional tolerances. The drawings are part of the Engineering Research & Development Division's technical documentation for a mechanical component, likely for a military or aerospace application.
